The conference was held at the Aberdeen Exhibition and Conference Centre from 27 to 29 March 2001 and was supported by UKOOA, TUC, IADC, OCA, IMCA, BROA and WSCA. This event followed the successful Occupational Health Offshore conference held in 1996. Twenty-nine papers were presented and over 160 delegates attended. The range of papers reflects diverse areas of interest: • • • • • • scene setting - policy, strategy and leadership the management and implementation of occupational health (including use of data, performance measures, cost effectiveness, health promotion etc) occupational health in the offshore design process practical control of health risks (e.g. noise, radiation, chemicals) the occupational health and human factors interface (e.g. how attention to human factors can address health issues such as those related to stress and shift work) well being and fitness for duty The range of speakers was also wide, including representation from offshore operators and contractors, occupational health practitioners, trades unions, academics, consultants and regulators from Britain and Norway. The aim of the conference was to raise the profile of all aspects of occupational health offshore. It provided an opportunity for everyone - including managers, supervisors, occupational health managers and practitioners and workforce representatives - to share views, challenges, successes, case studies and research findings. The conference was not designed to develop solutions to specific problems or find ways forward on contentious topics. However, some of the presentations and audience comments do offer such opportunities. These will be addressed by the HSE and carried forward by various routes (e.g. OIAC and Step Change). The proceedings are a mixture of formal papers and presentations; the decision on which format was used for the individual papers was the author’s. The papers published here have not been subject to peer review - although some have the support of various committees. They have been subjected to some editorial work, mainly to ensure consistency of textual presentation. The question and answer sessions, which were transcribed from audio tapes, have been edited to convert, so far as is possible, the spoken word into a readable text.

I endorse his view that this is an ideal opportunity to reflect on what has happened in the last five years and to refocus your attention on the important issues today. Revitalising and Securing Health Together The Commission and the Government strongly support work to address ill-health in the workplace. Last year the Deputy Prime Minister and I launched the Revitalising Heath and Safety initiative. I was in Edinburgh two weeks ago hearing from a range of Scottish organisations about how they are putting into action Securing Health Together, the occupational health strategy for Great Britain. It injects new impetus into the health and safety agenda and identifies new approaches to reduce further rates of accidents and ill-health caused by work. Especially approaches relevant to small firms - although there are relatively few of these offshore. I was impressed by the partnership activity in Scotland, for example, through organisations such as Scotland’s Health at Work. Partnership is central to our strategy. So far as Securing Health Together is concerned, to borrow the phrase from the (Ronseal) advert, ‘it does what it says on the tin’. Securing Health Together. The watchword is together. Revitalising aims to ensure that our approach to health and safety regulation remains relevant for the changing world of work over the next 25 years. It also aims to gain maximum benefit from links between occupational health and safety and other Government programmes. You may be interested that one of the delegates in Edinburgh, from Strathclyde Fire Brigade, said they had trialed providing injured firemen with physiotherapy. They found a payback of two pounds for every pound spent. We will be following up for more details. But it is an interesting indication of how investment in occupational health can pay. Securing Health Together is an essential part of Revitalising. Work that contributes to it will ensure that we meet targets to reduce the cases of work-related ill-health and absence. You will hear more about Securing Health Together from Sandra Caldwell later today. This conference gives you the opportunity to consider how we can Secure Health Together on the UK sector of the Continental Shelf. Let me ask you to consider why occupational health is important. Around two million people in Great Britain suffer from some form of work-related ill-health. These two million people are not on their own. At home their illhealth will affect their families. At work it means their skills and experience are likely to be wasted. Can your company afford this loss? Can we as a nation afford it? Occupational health in Great Britain I’m going to consider: - Revitalising and Securing Health Together - occupational health in Great Britain and offshore - how the industry has moved on in the last five years - how legislation relating to health has changed - ill-health issues offshore - baseline data and targets - the way forward and the key challenges Occupational health Offshore Occupational health is vitally important for the offshore industry. Unless you see it as such, progress will be limited. If this conference is the success that it deserves, and which I’m sure you all want, it will raise the profile of ill-health offshore. If this increased awareness prompts everyone involved with occupational health to do 3 As a result some platforms belonging to BP, Conoco, Marathon and Shell have progressed, through bronze and silver, to reach the gold award. This is exactly what Securing Health Together is all about. something, there will be fewer cases of occupational ill-health among the offshore workforce. The offshore industry, industry associations, trade unions and HSE, over the last five years, have all done an excellent job of raising awareness and developing action plans. But there is no room for complacency. There is much more to be done. Later I will challenge you to move occupational health offshore forward. If the number of cases of ill-health is to be reduced, everyone’s recent efforts need to be maintained or increased. Also, Step Change has been working on the Vantage card system - the Offshore Passport. The information this will carry means it has the potential to become a very valuable tool. All these developments indicate that companies recognise that a healthy workforce is good for business. Ill-health is as likely to occur from work offshore as it is onshore. The reasons for tackling it are no different. It is in everyone’s interest to do this for sound moral, legal and economic reasons. Step Change provides valuable support. It is an industry initiative, funded and voluntarily staffed by the trade unions and the industry to improve offshore health and safety performance. It has taken on responsibility for catalysing and monitoring progress with the industry’s contribution to Revitalising, and for keeping HSC’s Offshore Industry Advisory Committee (OIAC) abreast of developments. It has also worked jointly with OIAC to develop and run a workshop to set offshore Revitalising targets, which are an important part of developing a way forward for occupational health offshore. I hope Malcolm Brinded will say more about Step Change. Improvements can only be achieved if the offshore industry and everyone involved in it takes occupational health seriously. People’s health at work must be properly managed. This does not mean it is the sole responsibility of offshore managers and the medical profession. Everyone has a role to play, by which I mean everyone in the industry, industry associations, trade unions as well as HSE. Partnership is at the heart of Revitalising and Securing Health Together. You must look for opportunities to improve existing partnerships or forge new ones and decide what you are going to do to help reduce the incidence of ill-health offshore. How the industry has moved on in the last five years The offshore industry has changed in the last five years. Much more use is made of new and developing technology. Oil and gas are also now being sought in new locations - for example west of Shetland where the weather conditions are more extreme and travel times can be lengthy. Today much greater use is made of contractors. The number of people working offshore has come down from around 27,000 in 1996 to 19,000 today. The demands on these people have for the most part increased, for example by multi-skilling, team working and through more campaign based maintenance. The effect of one person’s inability to perform their duties is likely to be more noticeable today, than five years ago. As there are fewer people offshore, absences create extra pressure and increased stress levels, and the length of tours may increase. The last conference, in 1996, raised the profile of occupational health offshore. It gave all those with an interest a chance to be heard. At that time, many delegates felt that occupational health was a "Cinderella" subject offshore. But this was not surprising in view of the industry’s need to focus on controlling major hazards. The conference was a good starting point for the offshore industry. It encouraged discussion of occupational health offshore. But progress has been slow. It is essential that this conference stimulates action by those who can influence occupational health offshore. There is no quick fix for occupational health - securing improvement takes much time and effort. But there have been some significant developments. Today health certainly has a higher profile offshore. The industry has done much good work in raising awareness of health. Some offshore companies have taken up the challenge of Scotland’s Health at Work scheme, which focuses on health promotion. How legislation relating to health has changed On the legislative side there have been changes too. New and revised legislation applying both on and offshore has come into force, such as 4 the revised Control of Substances Hazardous to Health Regulations and the regulations aimed at controlling the health risks of asbestos and lead. The Noise at Work Regulations now apply offshore and the Approved Code of Practice on offshore health care and first aid has been revised. All these require people to focus on health. as a result, fatigue and stress. Difficulties with manual handling arise for catering staff because of the lack of space. This is a significant list of problems for a group of people who do one of the jobs that is traditionally seen as less demanding! The results from HSE’s inspections indicate that there are still areas where improvements are needed - especially in terms of assessing and controlling risk. This is true of even well known hazards such as noise, vibration and hazardous substances. Last year about 25% of the improvement notices issued by HSE’s offshore inspectors were related to health or welfare. Effort needs to be concentrated on all health and welfare issues and not just those covered by specific legislation. Currently our main source of information on ill-health and injury is the reports legally required under the RIDDOR. Each year HSE publishes a summary of these as offshore statistics on reported injuries, ill-health and incidents. The latest report indicates that last year the main reported cause of ill-health was chicken pox. Whilst the cause is beyond our control, it highlights the problem of transmission of diseases in the unique offshore environment. HSE is playing its part in other ways too. Not just through Revitalising, Step Change and the other initiatives I have already mentioned. But also through routine work on inspections and seminars to launch case study guidance - for example, “Sound solutions offshore” (noise control case studies) and “Well Handled” (manual handling control case studies). HSE was surprised at the low level of the number of cases of work related dermatitis being reported. Dermatitis is a disease that occurs at a significant level in other related industries and other countries’ offshore industries. From the reports that are being made, or rather not being made, it seems very likely that some work-related illness is not being reported. Some of this may be partly related to legal requirements. For example, for a disease to be reported the regulations say that it must have been diagnosed by a doctor. As you know there are no doctors offshore, and in many cases people will have recovered before they go onshore. Ill-health issues offshore HSE is working in partnership with the industry on a number of joint research projects to examine aspects of health. A number of these will be covered later in the conference, for example, on the health effects of exposure to toxic substances in drilling muds, and on adaptation to shift work. HSE and some individual companies are also developing partnerships, as part of the philosophy of Securing Health Together. For instance, the guidance on health in design will be piloted by two companies. You will hear more about this tomorrow. Companies tell us they see stress and musculoskeletal diseases as important. Work related stress is not reportable, but we are aware of individuals with stress being medivaced from offshore. We know that musculoskeletal disorders and stress cause the greatest number of cases of work-related illhealth across all industries. Let’s now look at one area of occupational health in the offshore industry. I’ve been offshore several times, and know something of the realities of working offshore. I’ve seen how in many ways offshore working conditions have no onshore parallels. Consider catering staff, a perhaps less obvious group of people, who perform a key role offshore. Many of the risks they face will be found onshore, for example, slips, trips, cuts and burns. We know too that noise and vibration are important offshore hazards. They can lead to hearing loss and hand-arm vibration syndrome. Reports of injuries indicate that manual handling is a major source of accidents and consequently ill-health. Manual handling represented 28% of all injuries reported last year and in many cases will lead to long term absence from continuing back pain. HSE is dedicating a seminar to the very important topic of offshore manual But offshore catering staff also face additional stressors like vulnerability to complaints of their colleagues, absence from their families for weeks at a time, low manning levels, and, 5 handling later this year, where it can be explored further. ideas and approaches aimed at improving offshore health and safety. Our experience is that all involved in Step Change are committed to making real improvements. Baseline data and targets Targets are powerful tools. If they are palpable they can bring people into partnership, allowing them to consider radical changes, helping to avoid the temptation to blame others and enabling people to share and be involved in meeting those targets. Once set, targets are an incentive and allow people to measure their progress. Later this afternoon you will hear about the “Challenge of setting Occupational Health Targets”. To achieve these improvements requires the commitment of the most senior people in the industry. I therefore welcome the attendance today of Malcolm Brinded and Roger Spiller. I find when people at the top are involved and prepared to commit resources in order to change attitudes and culture, then things begin to happen. I’m sure everyone here is committed to reducing ill-health amongst the offshore workforce. We all need to spread this message, not just to our immediate colleagues, but throughout the industry. I hope what you hear in the next three days will help you do this. The Revitalising workshop identified the lack of baseline data on work-related ill-health as a major hindrance to setting offshore targets. It concluded that a cross-industry database would enable the industry to establish a baseline against which it could measure its progress. Key challenges Such a database would capture all the data at present recorded by offshore medics in their logbooks or other ways, and data arising from sickness absence. The workshop agreed it would be a good idea to develop a scheme for classifying, coding and collating reports. It also agreed that the proposed database should be managed by an independent academic body, to ensure both confidentiality and quality. To summarise: In the next three days I would ask you to consider occupational health in the context of working offshore on the UK sector of the Continental Shelf, in order to identify ways to reduce occupational ill-health there. This work will be taken forward by a working group under the auspices of Step Change. A pilot study will be carried out and evaluated in the next year. Then the database will be launched in spring 2002. To measure your success in dealing with occupational health offshore, you will first need to establish a baseline and I support your plans to do this. Once you have determined the baseline, I challenge you to improve on it. Industry is of course also free, if it wishes, to develop other more stretching targets than those under Revitalising. What is vital is not to lose the momentum. Improvements can only be achieved if everyone involved in the offshore industry takes occupational health seriously. People’s health at work must be properly managed. I challenge you to decide what are you going to do to help manage ill-health offshore and then do it. I challenge you to move the topic of occupational health offshore forward. The way forward So how can we deal with the significant issues offshore? I believe it comes down to management of the issues. There are three main groups of people who can provide leadership to achieve this: employers, trade unions and the regulator - HSC and HSE. Providing effective management and leadership not only requires the three groups to work independently, but also to do so in co-operation with one another, for example through OIAC and Step Change. Finally, I challenge everyone involved in occupational health offshore, to make sure that the next five years are marked by a significant reduction in the number of people who become ill as a result of working offshore. Thank you for your attention. I believe it is right that the offshore industry and trade unions should be driving forward 6 Answer – Mr Bill Callaghan, HSC Some people say there are too many conferences. I think the important point is not the frequency of conferences, but the point I was trying to emphasise in my talk about what action happens in between. I think we do need conferences every now and again to raise the profile and raise the awareness. But I hope you will have taken from my talk that it's not just enough to have conferences. The important thing is what action flows from conferences. Today and the next couple of days need to establish a sense of common purpose. What I'm looking for is not more conferences necessarily, I'm looking for more action. QUESTIONS AND ANSWERS SESSION Question - Chris Hopson, Upstream Newspaper Bill, you've talked about these five-year targets just now. Could you elaborate a bit more on the kind of measures that the Commission and Government are looking at, to enforce those targets in the longer term. Answer – Mr Bill Callaghan, HSC Well the Commission has recently discussed its strategic plan and we discussed this at an open meeting with our stakeholders – Paul (Davies), you were part of the panel on that day. In terms of the commitment of HSE resources, we are clear that we need to prioritise our activities in three key sectors and on five major hazards. I can perhaps go through what those are at a later stage. I think the important point to stress to this conference is that achieving our outcome targets is not just a matter for HSE and its enforcement effort. This is why I'm delighted to accept invitations to speak to audiences such as this. Question - Mark Gibb, Blowout Magazine So what can be done about keeping informed about what is actually happening? Answer – Mr Bill Callaghan, HSC Later this afternoon you'll hear from Roger (Spiller) and some others about the Step Change initiative and the monitoring and arrangements that are going to be put in place to provide feedback and to keep information coming, so we can track performance against our aspirations. Achieving the targets is going to be brought about by our stakeholders, industry, employers and trade unions representative of employees, improving their health and safety. I strongly believe that's the main way we are going to meet those targets. It is not for us from the Commission to come and say your target for the next five years is 'n' percent. What we want to happen is our stakeholders to be working together to develop and own their own targets for their particular sector. Then drive through those management and culture changes which are needed to achieve the targets. So yes, we're going to prioritise our efforts, but we see a key role for our stakeholders. Question - Mr Graham Cowling, Acoustic Technology Ltd On your last slide you specifically referred to a managed approach to reducing health risks offshore. Is your request to see that approach, based on any concern about the way things are being handled at the moment? Answer – Mr Bill Callaghan, HSC The key point here is that occupational health is not just a medical issue. The danger is that people see occupational health as a question of doctors and nurses and of course yes, that's important. The key point I want to emphasise is that if occupational health is going to be improved it needs a concerted management effort. That means finding out where you are at the moment. That's the importance of base line data, setting what I hope are stretching targets to then improve from. It's having a proper approach to do this, so that's the importance of managing this process. A fundamental part of health and safety management is continuous improvement. So I do hope that we can engender that spirit through this conference and encourage all those offshore to see occupational health and safety as a key performance indicator for managers offshore. Comment – Dr Paul Davies, HSE If I could just add, I think also the government is committed to making a major contribution itself. The government is a big employer both directly and through contracts. It will seek to ensure that it is an exemplary employer by exceeding the target that is set for the country as a whole and ensuring that its contractors do as well. Question - Mark Gibb, Blowout Magazine Five years between conferences doesn't seem to impart a sense of urgency to finding solutions? 7 8 SECURING HEALTH TOGETHER – AN OCCUPATIONAL HEALTH STRATEGY FOR GREAT BRITAIN Mrs Sandra Caldwell, Director of Health, HSE I am going to give a brief overview of the Securing Health Together Strategy – as, though I know many of you will already be familiar with it, there are some of you who may not be. I will outline some of the key aspects of HSE’s contribution. Work has already begun to implement the Strategy and so I can share with you some of the early actions and finally I would like you to be considering how this applies to your work as I will conclude by asking you what you can contribute. Costs of occupational ill health Unfortunately we can be certain that the trend in the rate of deaths from mesothelioma continues to rise steeply (as it has since 1968). In 1998, 1527 people died from mesothelioma – a legacy from their exposure to asbestos in the period from the 1930s to the early 1980s. Though we are hopeful that the falling number of under-50s affected may reflect better control of more recent exposure to asbestos this is an area in which we will continue to be vigilant. Nationally, if we are going to make a difference to the overall levels of work-related ill health we must tackle the causes of the big two – Musculoskeletal disorders and ill health arising from stress at work. I will tell you more about HSE’s plans – but you will also want to consider if the national picture is reflected in the offshore industry and whether you are currently looking at the right priorities. We know that despite good progress in reducing the numbers of accidents at work, we still need to strive to achieve a similar success in tackling the high level of work-related ill health we face today. From the self reported work related illness survey of 1995 we estimate that over two million people in Great Britain suffer from an illness they believe is caused by or made worse by the work they do. A study carried out by the water industry found that on average a case of work-related ill health cost a company at least two and a half times that caused by an industrial injury. Behind these figures is a great deal of personal suffering and family hardship, and cost to the individuals themselves, their employers and society at large. You may be interested to know about a major chemical company that improved their own system of using the data they collected on sickness absence to identify the causes of ill health in their workforce. Though they found that the work they had done to control exposure to sensitisers very effectively kept the numbers of asthma and dermatitis cases low they actually had large numbers of people with musculoskeletal disorders. This information prompted a change of approach and they introduced an early intervention programme that helped prevent ill health and got people back to work faster. The better targeting of their resources meant they found they got return for the money they spent. Musculoskeletal disorders were by far the most common self-reported illness, affecting an estimated 1.2 million individuals. The second most commonly reported condition affecting just over ½ a million was stress, depression and anxiety and those who reported that stress arising from work made existing conditions worse, such as hypertension, heart disease or stroke. We have not yet solved the problems of occupational diseases that arise from exposure to hazardous substances. We can estimate with some certainty that we have upwards of a thousand new cases a year of work-related asthma and some 3000 cases of occupational contact dermatitis are seen by dermatologists or occupational physicians each year. This is likely for both these diseases to be an underestimate. This type of approach is welcomed and we hope will be taken up by more organisations in order to contribute to Securing Health Together. I have heard a little about OIAC’s plans to introduce a new system of recording the health issues that cause workers to visit medics whilst offshore – this should lead to better data – making it easier to make decisions about what your priorities must be. I look forward to 9 hearing more about how the OIAC project develops. Of course these targets will only be achieved at the national level if action is taken at the workplace level. Securing Health Together Securing Health Together was developed through an open public discussion process to which I know some of you contributed. We heard and understood that what we needed to do to make a difference to this heavy toll of ill health was to think innovatively, be flexible and respond to both the complexity of occupational health problems and changes that arise from modern work patterns and working conditions. I would like to clarify that the second target concerning ill health to the public caused by work relates mainly to illness arising from hospital-acquired infection and therefore is unlikely to be a priority for the offshore industry. I hope that you will sign up to meeting the other targets. Targets are important because: • they act as motivators for action, • they make us focus on what we know about the current situation and whether we can affect the causes of the big problems; and • we must evaluate what we do against outcomes: we ask “does what I am doing really stop people being made ill, or help them to return to or take up work?” In light of this, Securing Health Together takes a broad understanding of occupational health embracing both the effects of work on health and health on work. Its overall aims are: • A reduction in work-related ill health to workers and to the public • A reduction in sickness absence • A culture where people are: o rehabilitated back to work following illness, or o provided with opportunities to work despite health conditions or disability. Partnership Securing Health Together is based on a partnership approach and will only succeed if the existing successful partnerships flourish and we take up the opportunities that new partnerships have to offer. At the national level there have been some events at which we have seen Partnership beginning to take the Strategy forward. I won’t dwell on these, but in brief: The offshore sector has of course always had a rather broader view of occupational health than many sectors onshore. As the offshore installation is the workers’ home as well as their workplace the employer has to partly replace the usual health support functions of the NHS on a day-to-day basis. Also the captive audience has already led to a tradition of good health promotion initiatives. That said, the setting of targets should stimulate you to review your approach to ensure you do have the right priorities. The Partnership Board, of which I am a member, has the role of producing strategic ideas; championing the cause; providing oversight on the progress that is being made and having a challenge function. We meet again next week and I look forward to having some feed back from today that I can add to the other conferences I have attended recently – we are keen to hear feedback on Securing Health Together and what you can do or are already doing to play your part. Targets We are clear about what needs to be achieved. Challenging national targets have been set and are supported by nine Government Ministers. By 2010 we want to • cut by 20% work-related ill health for workers; • and the public; • cut the number of working days lost due to work-related ill health by 30%; and • create a culture of rehabilitation, by ensuring that opportunities for rehabilitation or access to work are extended to everyone who has been ill or who has a disability – where it is necessary and appropriate. In December we held a workshop at which a wide range of stakeholders met who have an interest in how we can measure progress against Securing Health Together’s targets. We’ve not solved all the difficulties yet, but we learnt a lot and will soon be publishing a technical note that will set out what HSE in cooperation with other organisations and government departments will be doing. But 10 method will suit everyone, it will require flexibility and a multidisciplinary approach. Meeting the needs of small firms will be central. after all the best source of data is often the industry itself. Conferences to discuss Securing Health Together in action have been held • in Cardiff in October, hosted by HSE in partnership with the National Assembly for Wales; • and at Murrayfield just a fortnight ago, hosted by HSE with the Scottish Executive. Both events were well attended. At the latter I was pleased to hear from a selection of Scottish organisations about the actions they have already been taking to really reduce the number of people made ill by work or help them get back to work when they have been ill. I’ll say a little more about this later. HSE’s contribution I think it’s helpful to understand how the five programmes are going to be followed through to give you some examples of what HSE is planning to contribute to reducing the incidence of ill health arising from workrelated stress. • For Compliance we are working to develop standards of good management practice for a range of stressors. • For Continuous Improvement we will pilot local benchmarking groups to share good practice and knowledge about work-related stress in small and medium enterprises and between trade union safety representatives. The five programmes of work To explain how each of these bits of the puzzle fit together to contribute to Securing Health Together’s overall targets. We have set out five programmes of work. Over the next few weeks the Programme Action Groups will each meet for the first time. The membership of each is made up from leading players in the respective fields and they will oversee and facilitate the delivery of the Strategy's five programmes of work by identifying and outlining what actions must be taken. The five programmes of work each deal with aspects of what we need to do. • For Knowledge we are starting a programme of research to pin down some of the remaining questions about stress and its relationship to ill health. • For Skills we are developing training materials for managers and safety representatives on how to carry out a stress risk assessment. • For Support we will publish guidance to assist employers to manage stress that will keep up to date with the developments that arise from our other work. This approach is important because it helps to demystify health issues. We will concentrate on practical solutions where we have them as this helps managers and others to see how they can contribute. First we must improve the law on occupational health and the level of compliance with it. We are considering here not just the Health and Safety at Work Act and related Regulations, but also provisions under the Disability Discrimination Act. Second we want to move to a culture of continuous improvement where people collaborate, form partnerships and share best practice – often taking action above the legal minimum. We have already begun to plan our other key work along these lines, for example our strategies for tackling musculoskeletal disorders and asthma. Third we must share our knowledge and collect the data and other information that will help us reach the targets and evaluate how we are doing. The examples I’ve referred to on costbenefit analysis would contribute here. Examples of others’ contributions But I have focussed on what HSE has been doing. As I have already stressed the targets are only going to be achieved if others work in partnership to deliver them. Fourth we need to achieve a better spread of competence and skills – we want to have the right person for the right task. I said I’d heard some interesting examples of effective work to improve occupational health at the recent Scottish conference and I’d like to Finally we want to improve the delivery and targeting of advice and support. No single 11 tell you a little about those and some others of which I’m aware. What the offshore industry can do So there are many contributions at many levels. I would like you to consider how you, your organisation or the offshore industry as a whole can contribute. I know that over the next few days you are going to hear more about work that has already begun. The Scotland Back in Work campaign, run by the Health Education Boards on the basis of research by the Faculty of Occupational Medicine, was able to show that their simple message – that the best action to take if you have back pain is to get mobile and take normal pain killers – delivered through the right campaign – using local radio – had raised awareness and that resulted in changed behaviours. I recognise the achievements that many of you have made by taking part in Scotland’s Health at Work awards scheme and progressed through from bronze to gold. I am sure that you already value the benefits to the general health and fitness of your workforce. I think the message we can take from this is that efforts to manage risks can make a real difference – even in areas where the manager does not have direct control of the cause of the risk. If the same approach is applied to risks arising from the work processes the returns could potentially be even greater. Lothian Occupational Health Forum, a joint trade union and local health authority initiative, explained how their advisors had approached the issue by contacting the worker at their GPs’ and helping them explore the causes of their ill health and the ways of overcoming it. This did help individuals to return to work and in some cases the advisors were invited into the workplace to help advise on changes that could be made there to prevent further ill health. For example, you can look for ways of improving your compliance with existing health and safety law: • A major current programme of work for my colleagues in the Offshore Inspectorate includes investigation of manual handling accidents and their prevention. You can take up this and the existing case studies guidance and apply it to your own workplace – don’t wait to be inspected! You may need to consider if you have set up the arrangements you need to comply with the Disability Discrimination Act. I was particularly interested that speakers from the floor took up the need to look at costbenefit analyses for occupational health interventions. We heard the concerns about the costs of interventions. What we need to hear about are the costs of ill health – and the savings to be made if we prevent that. One consultant occupational physician referred to some work he’d done to establish a physiotherapy service that was so successful he’d lost the contract to in-house providers! It may not be possible to do cost-benefit analysis alone – a group of major UK companies are in the process of establishing a common set of data on their staff’s ill health and absence. They are intending to use this as the basis of research into the effectiveness of occupational health and health promotion interventions. So far they are in the development stage, but we will be keeping in touch with them and they have agreed to share their results with us all. You may be able to participate in initiatives that contribute to continuous improvement in the standards of occupational health practice • I know the industry and HSE’s Offshore Shore Directorate has already run some seminars for companies that manufacture equipment that is associated with hand-arm vibration on the best ways to assess and control exposure. • I also know that Offshore Directorate has projects with various offshore companies and industry associations developing standards and guidance on a range of topics, including stress management, manual handling aspects of scaffolding work, assessment and control of exposure to mud chemicals and design. Indeed you will hear more about some of these later in the conference. On a bigger scale again the companies in the water industry have signed up to Clearwater 2010 – a campaign to reduce the ill health caused by work in workers in the water industry and allied construction workers. They have set targets and are concentrating on tackling priority ill health issues by setting specific goals across the industry. I am sure you can think of more examples. 12 you can overcome any difficulties. Often occupational health problems need solutions from multi-disciplinary teams. Do you understand the services that your partners provide and how to access them? Are you one part of the solution and can you improve how you work with others? As I mentioned earlier I am very pleased to hear about OIAC’s cross-industry initiative to improve our knowledge about the sorts of ill health that occur offshore, by recording the reasons for visits to medics. Data collection is not straightforward. We need it to measure trends so we can show what we do is working – or learn if it is not. We also use it to choose our priorities and you’re probably already in a position to do this – if you reflect the national situation those will be stress related ill health and musculoskeletal disorders. I suspect the answer will often come in the form of partnership. In particular, partnership is likely to be the answer to how we get the message across to all parts of the offshore industry – the smaller enterprises as well as the big players. This is one of our biggest challenges to which I know we do not yet have the right solutions. On the last two programmes of work I am going to suggest areas that I would like you to consider: Concluding remarks There are a wide range of skills that are required if we are going to have the right people to do the work that is needed to reduce the toll of work-related ill health and get people back to work who have been ill. However, at the centre of any action is the manager at the workplace and all our efforts hinge on his or her understanding of the causes of ill health absence (whether that is work or home related) and whether the right techniques are being used to encourage people to return to work when they have been sick without increasing risks to themselves or others. Do you have access to the sorts of management of attendance courses that you or your managers need? Do you support managers to attend such courses? Can you provide this sort of training? I have run briefly through the key aspects of the Strategy at a national level, some of the first actions taken in partnership and what HSE is planning to contribute. The five programmes of work are the key to the way that we will begin to make progress. When I began I asked you to consider how this applies to your work and what you could contribute … I would be delighted to hear from you as individuals if you can catch me in the margins here. Or our Securing Health Together Team at HSE, London are collecting examples of work that people are contributing – you can find out more and submit an example by visiting our website at www.ohstrategy.net. I would like you to consider whether or not you have the support that you need to improve your occupational health record. By support I mean access to information, advice, skills or resources. I would like you to consider how QUESTIONS AND ANSWERS SESSION Delegates were asked to save their questions for later. 13 14 KEYNOTE SPEECH Mr Malcolm Brinded, Managing Director, Shell U.K. Exploration and Production 15 16 • • • • • • • Thank you Paul (Davies) I am very pleased to be speaking at a crucial conference on a topic which is so very personally important to us all In the coming thirty minutes, I hope to present how Shell Expro is tackling the challenges of occupational health onshore and offshore, how managing health plays a key role in our companies values, and especially the key role of leadership in helping progress the agenda on occupational health. This last issue is of crucial importance since it is so easy for company managers to assume that because they are not themselves experts in the field of health, that therefore Health Management is not something they need to be involved in. This is quite simply wrong. 27 M arch 2001 Occupational Health Offshore Shell U.K . Exploration and Production M anaging Director M alcolm Brinded D eliver ing on H ealth • • • • • • I would like to start by reminding ourselves why it is that we believe occupational health is so important - indeed why the conference here these three days is so important to us as an industry compliance with legislation is the beginning and a key driver for us - but we will not limit our ambition to compliance. Later I will discuss the needs for a more rigorous system to ensure improvement in our health management we must control our losses through direct and indirect absence cost and lost business opportunities - several millions of pounds per annum We are committed to protecting all the people involved with our operations - a moral imperative of leadership at the core of Shell’s Business Principles Health management is not just about being reactive - it is a key factor in unlocking potential - helping our people in giving their best So where does health management fit in our agenda?... • unlocking potential • protecting people • loss control • compliance Tackling the need… seizing the opportunity W hy manage health? 17 • • • • Respect for People Fair L eadership Honesty and Openness Integrity Pride Clarity of Purpose Sustainable Development Teamwork and Prof essionalism Trust • • • • • • • • • EXPRO VALUES DRIVE LOCAL BEHA V I OURS Shown here are what the people who make up Shell Expro determined to be our key values. Thousands were involved - evaluating behaviours of staff against these values is part of their annual appraisal One of the absolute values we hold is our respect for people This means that in all our operations, we must ensure the safety, and the health, of all our staff, and all those who are affected by our business, including our contractors and our communities close to our plants and facilities Outstanding Business Performance • T eam E xpr o V alues • • • • • • • • • Improved Staf f Commitment, M otivation & Performance Recognition & Rew ard M ore Stimulating W ork Environment The key values and behaviours I have shown are an integral part of that we call our Employee Value proposition - what is the deal between our company and the people who work for us: Attitudes and behaviours has particular relevance for personal health and levels of psychological illness in the workplace. We cannot be serious about this strategy unless we protect and enhance our people’s health. What is the purpose of our focus on our Employees - it is the abilility to unlock potential and achieve an improved Staff commitment, motivation and performance This has been instrumental in Shell Expro’s successful transformation over the last decade, and will be vital in meeting the challenges ahead of us Other elements of the Jigsaw are also relevant to health: A stimulating work environment, with a healthy work-life balance, thoughtful ergonomics, encouragement for health and personal fitness improving health is a natural fit to this whole agenda and we see it as a prerequisite for the success of our other key strategies, such as Step Change in Safety In short, not only will we comply with the law but will seek all opportunities to add value to our business through our people.

Earlier this year our Shell Tankers and Trading lost a court case concerning mesothelioma - more than 45 years after the period of employment. The crux of the case concerned whether the company should have known the link between exposure to asbestos and mesothelioma in the mid 50’s. This is not a complaint, but a comment on the need to recognise the tong term implications of getting health management wrong We see Managing Occupational Health as an absolute necessity, and increasingly prominent on our agenda. So what do we in Shell Expro believe falls under the management of Occupational Health... • Renewed focus on health – impact of poor management is not immediately visible – health is very personal • K ey Challenges • Health is in “ supporting cast” • Safety gets “ top billing” • Integrated Health and Saf ety management O ccupational H ealth • • • • • • • • • Reducing the impact of illness or injury Promoting health and healthy behaviours First of all our vision: "people giving their best" through improved health and performance. An ambitious target not restricted to loss control. adopt an inclusive, accessible and far reaching agenda, we must include contractors and business partners in our ideas, including them in our key activity programmes - we are extending the role of our off shore medics to include health promotion and safety at work. Our philosophy is to take the message to the workplace. Work on health in three key areas preventing work related illness limiting impact of illness though early intervention promoting health and healthy behaviours First I shall describe Shell Expro’s approach to these three areas I shall then go into the role of leadership, and some of the five key areas highlighted in the HSE’s strategy as outlined in the Securing Health Together document C o m p liance C o n tinuous improvement Knowledge Skills Support Leadership Preventing work related ill health People giving their best through improved health and performance A strategic approach to health 19 Inc g sin r ea So p tic his ati on preventing work related illness • We are continuously progressing the boundaries and becoming more sophisiticated in our understanding and approach to work related illness • noise, vibration, COSHH have been managed for a longer period • especially we recognise we must still tackle musculo-skeletal illness • A Manual handling initiative in being progressed in the Northern Sector • Programmes are in place for Display Screen Equipment Risk Assessment and training • a key role in this is ergonomics - getting it right from the outset in the design stage - for example on Shearwater, we invested heavily in an ergonomics study. Key outcomes were a maintenance philosophy of ship-to-shore for equipment repair, minimising manual work in sub-optimal confined spaces, and consideration for the location of valve handles. A great help in defining the ergonomics was the significant involvement of offhore operators in the design • Our latest work is also focussing on Mental health issues - and I will return to this later • An important step in all these programmes is full involvement and participation in the offshore environment. • We are utilising our offshore medics as an invaluable resource in this respect with their role being enhanced and developed to include health promotion and training skills Noise COSHH V i bration M usculo-skeletal Ergonomics M ental health Pr eventing wor k r elated ill health • • • • • • 0 40 60 80 1998 2000 fa v o u r a b le r e s p o n s e s (% ) 20 100 These are some results from our 2000 Shell People Survey, which is vital in showing the experience and feelings of our staff and contractors vs two years ago Shown here the relative movement on key questions from the survey relating to our commitment to the safety, and to the health, of our staff, two key measures on whether we are meeting our objectives of demonstrating our respect for people There are two points I would like to highlight: firstly, we can be quite proud of the significant improvement in Staff belief in our commitment to safety, relative to early 1998 - with our attention moving to leading vs lagging indicators secondly, there is clearly a lot of work to be done before we are at the same level with health 1998: 47% feel excessive pressure, in 2000: 53% G o o d W o r k / life b a la n ce N o t Ex c e ssive W o r k Pr e ssu r e N e v e r i g n o r e sa fety r u l e s Sa f ety T a k e s Pr i o r i t y Shell Survey R esults - Expr o 20 limiting impact of illness though early intervention • excellence in first aid and emergency response Expro welcomes the new approved code of practice in offshore first aid • effective April 2001, in particular risk based approach. This supports our view and practice that effective casualty management starts with the immediate aid of a colleague, and progresses through to the offshore medical support and evacuation from the installation as necessary. UKOOA are also working on medic training and competencies and we welcome this • expertise in offshore emergency medicine • Key to offshore medicine is communication and effective links with secondary and tertiary care centers on the beach. We like the look of BP's "Way 2 Go" project looking at the increased use of telemedicine in the offshore environment and we look forward to seeing and understanding the opportunities this will give us. • early and active rehabilitation of the ill/injured • We have very few injuries /absences through ill health - about 1% of the workforce at any one time. However the costs of an absence in the offshore industry are very high - about £700 per day. So early and active rehabilitation is vital. We utilise flexible working practice (part time, work from home ) for our on shore staff and offshore are using detailed case risk assessment to decide when we can safely return employees to the offshore environment. We are challenging previously held beliefs that some illnesses prevent offshore working - e.g. on diabetes. Of prime importance is what the individual wants. We should remember that it is the "safe functional capacity that counts and not the illness label" – “ safe functional capacity” counts, not “ illness label” • early and active rehabilitation of the ill/injured – communication and secondary/tertiary care centres • expertise in offshore emergency medicine – new approved code of practice • Excellence in first aid and emergency response L imiting impact of illness thr ough ear ly intervention promoting health and healthy behaviours • challenging health behaviours • obesity, inactivity, smoking, alcohol and substance abuse • Awareness programmes • Health promotion programmes - in the current year we are running programmes on healthy eating, exercise, travel health, infectious diseases and drug and alcohol awareness • A key area to focus is on our work/life balance - and there is a key role here for leadership by example - I know how I struggle • The provision of sports facilities on and offshore, and the encouragement for Sports is key, in Aberdeen through the Pecten Club and the Woodbank facilities • I know that I should do more here myself! • you may find it hard to believe that I used to run marathon’s - 15 years and 3 stone ago! • that may not easily return, but personally I am committed to my step change personal contract - including regular exercise, and I am very lucky to have received the commitment of my colleagues to help support me achieve those goals • Sports facilities • W ork/life balance • A w areness programmes – substance abuse – alcohol – smoking – inactivity – obesity • Challenging health behaviours Pr omoting health and healthy behaviour s 21 • ng asi cre e D inf nce lue It is vital to recognise that the three areas of focus I have just described apply to all people involved in our operations offshore – we have traditionally focussed on our Shell staff, but have recognised that we have life of field alliances with our integrated service contractors, and we are well advanced in ensuring like-for like treatment, encouraging our core contractors to adopt policies and practice to at least our standard – our influence on itinerant offshore contractors is smaller • as a minimum, we provide identical offshore medical facilities and care - but we are increasingly checking on the wider health management practices of such employers – the hardest group to influence are the contractors on the ships, rigs and barges involved in our operations • we will encourage our regular contractors to develop health management systems comparable with our own to ensure the protection of their staff Shell staff offshore Itinerant offshore contractors Core offshore contractors Contractors on their installations H ealth management thr ough the supply chain • • • • Common to managing the three areas: – preventing work related health – reducing the impact of illness – promoting health and healthy behaviours first of all leadership, and the five key programme topics from the HSE strategy I shall first of all focus on the role of leadership, then I shall discuss managing continuous improvement and competence and skills development, presenting some key data from Expro • Support • Skills • K nowledge • Continuous improvement • Compliance • L eadership M anaging Occupational H ealth 22 • • • • • • • Vital that all companies have clear leadership on HSE and especially health, which can be neglected part.

This is a measure of psychological health and shows a stable trend over five years with the Expro population comparing well to the general population. There are however significant numbers of people in the company who are operating with significant levels of distress and this is wasteful. Not only is there a human cost but a lost business opportunity as 15% of our human resource will be performing at less than optimal levels. We consider that Expro is a leader in this area.

Work place examples include Display Screen Equipment programme utilising a computer based training package which is simple, effective and highly accessible to all of the workforce via our intranet page. A review of manual handing in the offshore environment is underway to attempt to reduce injuries and absence from this activity. It will look at both organisational issues - the workplace, the way we do the job but also personal skills including risk assessment and safe lifting. Managers have received specific training on stress during change management, for example for the move of our staff from London to Abderdeen following the sale of our London Head Office in 1999 competence is more than knowledge - it involves behaviour modification to achieve this we need buy in and active participation.

I don't know whether there's anyone who can give me a supplementary comment on that? Una? Question - Gareth Powell, BP One of the things you mentioned was making greater use of your offshore medics and increasing their skill base. I just wondered if you would like to comment on two aspects of that. One is when multi-tasking of medics is required and whether being asked to do nonmedical functions might detract from their medic functions. There is also the question of outsourcing as against direct employment of medics. Comment - Una Corpe, Senior Occupational Health Nurse, Shell Expro The sickness absence rate for Shell Expro in 2000 was just about 1%, which has dropped from previous years. The sickness absence rate is very low by comparison to national figures. As regards occupational health reporting, we've got a system in place where all cases that are reported through the offshore medics and through the onshore occupational health focal points are screened thoroughly and investigated to identify the causation for the reported cases. All cases that are reported through the occupational health system are actually then recorded. There isn’t under reporting unless they haven't been brought to our attention. Answer – Mr Malcolm Brinded, Shell Yes I think they are both important. I'll take the second one first. I think in the end, the key is getting the right skills. Wherever you obtain that from, you want to have the right skills, the right levels of performance and the right commitment. If you outsource because you regard it as more likely that you'll get long term the quality of people that you want, it's no good saying it's no longer my problem. It may actually give you more issues to focus on than if you had traditional in-house capability. I think multi-tasking is an important issue. It is a reality that we have reduced numbers offshore. On some installations, where 10 or 20 years ago there were 200 on the installation and a high degree of activity - and unfortunately of safety incidents and injuries, the medic was 100% occupied as a medic. Comment - Malcolm Brinded, Shell I suppose my only comment would be I suspect there still is under reporting. I don't think it's any worse, so I think that trend is fair. But I suspect all of us have an intrinsic under reporting in some ways, particularly because of this lag effect that I referred to earlier in terms of time delay. I feel good that the trend is right but I'm sure that there are more cases than those statistics pick up in one way or another. Where I think we have gone wrong, is to miss where the workload on those individuals becomes unmanageable and their core role as a medic is in some way diluted by the other tasks they're asked to take on. That can happen particularly during periods of upmanning to, say, do a summer shutdown. We've got the same medic that we've always had, then comes the summer shutdown, two or three times the manning on the installation, and you've not actually changed and supported the medic to take on that additional burden. That's the way I see it. Question - Jake Molloy - OILC Offshore Union Malcolm, I was wondering if there is any significant difference between the statistics for Shell staff and those of contractor staff on sickness absence etc. If so, would you hold with the view that perhaps this is as a direct result of the significantly less hours exposure for Shell staff compared with their contractor compatriots. Question - Dr Eirik Bjerkeboek, The Norwegian Petroleum Directorate You showed us that you have quite a clear-cut decrease in the case rate of work-related illness during recent years. You also touched on the issue of under reporting, and that you don't reckon that has increased, but do you see a comparable drop in sickness absence? Answer - Malcolm Brinded, Shell My understanding is that where we've got good data, which is around offshore staff of our core contractors, then we don't see such a difference. To go on to your second part, I don't think there is a factor there in terms of difference in the hours worked. I think it is a 28 on our installations. We've got good data for those, with no obvious difference in statistics but we haven't got data that extends properly into further up the staircase that I referred to earlier. It took us a long time to get there on safety, but I think we have to get there on health as an industry. concern that we've not done as well in really capturing what is happening on the contractor managed installations and perhaps to a certain extent the itinerant work force that comes and goes around the patch. So in terms of 80% of staff offshore, typically 20-25% are Shell staff and of the remaining 75–80%, the majority, 80%, of those are core staff who are long term 29 30 OFFSHORE INDUSTRY ADVISORY COMMITTEE PERSPECTIVE Mr Roger Spiller, MSF Offshore Team Leader insurance premiums; reduced productivity/efficiency; higher safety risks. The role of OIAC The Offshore IAC is part of an extensive network of Advisory Committees which the Health and Safety Commission, the Executive’s governing body, set up to provide advice to the Commission, issue industry guidance and to promulgate best practice not good practice. An important point – As low as is reasonably practicable. Health not occupational health – cause is irrelevant if the worker is unable to work or is ineffective – cost/inconvenience to employer are the same. Integral to success is rehabilitation which is not good due in large part to perhaps to the historic organisation of the industry where operators gave responsibility but often little authority to Contractors who simply recruited a replacement. Not any more. All ACs are tripartite bodies with employers, government and the trade unions represented. Additional members representing the wider public interest are now being introduced along with greater transparency. Last year change in name from “Oil” to “Offshore” to focus more clearly. Post Piper Alpha the emphasis was on new regulations and guidance promoting safety resource shortage inevitably meant too little regard for Health. Unique series of problems for OIAC – workers spend half their life offshore including leisure time. Revitalising Health and Safety and Securing Health Together – Cross departmental commitment from Government. Ministers are involved and remarkably well briefed - not leaving it to others and they expect action. Keeping an eye on what we do. Health (physiological and psychological) of families also relevant Review of IACs. Are we effective; are relationships too cosy; is our work relevant to the needs of the industry? If not, then they will either act without us, in spite of us or find a more effective mechanism for action. Gone are the days when if we couldn’t agree or reach consensus nothing happened. Government now want the range of options not the conventional wisdom a la MAFF. Revolution in working methods – maintenance, vendor, campaign and less planned; floating systems, sub sea; reliability. Globally mobile workforce – increasing proportion due to more overseas work with Aberdeen and elsewhere as source of expertise. But we have older platforms and smaller numbers with ageing plant tied in to a Changed workforce – higher proportion of contractors; ageing workforce; long service workforce. OIAC therefore has to prove itself dealing with Health Reduced numbers (35,000 reduced transport; greater reduced flexibility First is Problem identification – what problem? RIDDOR; cause and effect; short working life offshore; often long development time for disease; presentation of disease when the worker is out of the industry or retired. to <20,000); responsibility; Perception of Stress; insecurity; uncertainty; unreliability Costs to industry – skill shortage; training and assimilation; loss of knowledge; higher 31 The aim of this Conference is to raise profile and create an awareness of health as an issue as well as looking at the problems and some solutions Vantage Card both for storage of information and access to it Conclusion Problem solving – OIAC unique ability – Operators-various varieties of Contractorunions and various regulators (policy and operations). (HSE; CAA; MCA; DTI) All adds credibility to the total package thus better received by the workforce, not just further exhortation from employer. Industry is beginning to recognise the costs of ill health A partnership beginning to develop born out of OIAC and nurtured by Step Change Only way of tackling the problems brought about by – declining fields; reduced numbers; multi-tasking; additional pressures- stress; remote fields; incorporation of Working Time Regulations. OIAC in conjunction with Step Change – SC needs to focus on the practical avenues for improvement uniting the whole industry and all stakeholders about the issues and solutions. OIAC to take the political and more contentious issues forward. Big challenges will be how to deal with producing an integrated rehabilitation policy and programme and preventing psycho-social problems, some of which seem inherent in the industry, as required under “Securing Health Together”, securing the Offshore Industry’s contribution to Revitalising Health and Safety Workforce and management networks – best practice and informality Target setting criteria in hand – realistic yet stretching A great asset is the existing high standards of Occupational Health provision by some operators. Even greater is the availability of medics on each installation for recording; health promotion; consistent interpretation and a humanitarian approach to health issues. Conference will have succeeded if we are able to identify issues and develop ways of working together without fear of the consequences, but confidence in the outcome. 32 DAY 1 SESSION 2 SESSION THEME – OCCUPATIONAL HEALTH MANAGEMENT AND IMPLEMENTATION 33 34 THE MEDICAL MANAGER’S PERSPECTIVE Dr Jim Keech, BP, Manager Health BP Upstream UK, Chairman of UKOOA HAC cost' and 'bad cost' are often lost. We need to improve our financial management. As health managers, we need to understand about financial management, we need to talk to the accountants. They have, after all, been managing to convince the industry over the years to move forward, to invest in projects. Project Way to Go was mentioned earlier. For that project to move forward I have to complete financial memorandums, I have to learn the techniques, I have to find the 'switches and buttons' that make my management move. Unless I can learn that language, and unless I can find those switches and buttons I am not going to succeed. And health will not succeed - for us in BP at least. We had to get to materiality and to explain that we often work with very small budgets compared with the enormous prizes that there are in our industry - the millions and billions that we hear quoted. Very often our health budgets - and I control a budget of about £1 million - are small beer. Because it's small beer, and because it doesn't add in the extended health team, the medics offshore, the health spending (where the total health spend is somewhere in the region of £5-6 million), it doesn't reach materiality. It's too small therefore we can ignore it, therefore we can outsource it, therefore we don't need to worry. In business, if you cost a lot, somebody takes some notice. Maybe I don't cost enough! The management of occupational health is an aspect of my task which I take most seriously. We hear - and it has become somewhat cliched - that 'good health is good business'. Unfortunately at times that seems to have been the business of cost accounting rather than what I think the authors of the statement really meant. Proactive versus reactive The value of a medical has often been simply paraphrased to its price. That clearly isn't right. We have to change, to be proactive and not reactive. 'Medical' has been long associated with the oil industry but not necessarily 'health' and this is where we need to change. 'Health' is no longer something indistinct from safety. To perform, we need to ensure that health is seen as distinct from safety, no longer that silent 'h' in HSE. But health should not be separated from safety - it should learn and move forward together with safety. Managing risk - understanding the complexities Health is a complex issue but it's not helped by being seen as only the preserve of doctors and nurses. Many doctors and nurses are poor at explaining the complexities to their partners and to other managers. We can use the same business principles in health as are used elsewhere in our industry. But it is necessary for us as health managers to learn those business principles and apply them. Health and safety is very much about caring for people. 'Caring' is an awkward word for many. People feel uncomfortable and think it means 'motherhood and apple pie'. But it is about caring for people getting sick, it's about caring for people getting injured. Do you care enough to prevent them getting sick and injured? I think, as you'll see later, that there is a link into some processes which I hope you will take forward in your respective companies. Meaningful metrics How excited are you by the term 'occupational illness frequency rate'? It doesn't excite me much. This isn't the end of the truce between BP and Shell by the way. It's simply that, as a metric, this doesn't excite. It may be meaningful because this is what we have to be absolutely intolerant of. We cannot have occupational illness. Occupational hazards are not acceptable. They show that we are not caring enough. Occupational illness is what we caused, it's what we did, it was the work that made them ill. People shouldn't come to work to get ill, to get sick, to get injured. After all there is a healthy worker effect. Those in employment are healthier than those who are not, so let's build on that. Why not have those Value demonstration We have had difficulty in health with demonstrating value. When the oil price is up, we can talk about 'value'. When it's down, we only hear about 'cost'. The concepts of 'good 35 Occupational Health. His faculty is shared with the Faculty of Family Medicine and Community Medicine. So, within the same faculty, general practice and public health are all included. That is the place we are at in an offshore setting, where non-holistic is not an option. You do have to cover health - as health defined by the World Health Organisation, as a state of total physical, psychological and social well being. There is nothing wrong with that as a definition of health. Those of you who work in health offshore know you cannot get away with just focussing on one aspect of that definition. people who come to work going home healthier? What is wrong with that? Maybe we can make those kinds of differences. I think meaningful metrics will be a key. Sometimes we are very good at presenting metrics which we like and which we know we can manage. Sometimes we are going to have to get into the meaning. 'Sickness absence' is a preferred metric of mine, simply because it means a lot. If somebody is not at work a lot of money and a lot of pain are involved. We need to use that sort of meaningful metric - which is simple to understand and use and doesn't involve deciding what's an occupational illness and what isn't. After all, unless you can have clear definitions of occupational illness then your occupational illness frequency rate is not going to change and may be subject to manipulation. We need to provide a breadth of service. We are there 24 hours a day for a couple of weeks a month. There isn’t access to the general practitioner, to the counsellor, to all the services that are commonplace in an onshore setting. It's the whole person who comes to work, it's the whole person who gets sick, it's the whole person that needs to be dealt with. So 'holistic' could have a 'w' at the front of it we need to look at that totality of care. This brings us to the fact that we hear a lot about psychological health. It is said that psychological health is important. Many of our companies lack psychological health plans, because we have been dominated by physical health in the past. We need to work on this. I'm glad to say the HSE is stimulating us. They tried to stimulate us with an ACOP but fortunately other methods are now to the fore. I have worked hard with psychological health plans myself. I don't know if it's been making a difference yet but certainly we are tracking the data in the same way as Shell and others are, to see whether the plans are working. Managing to perform We have to manage to perform. We have to learn to start setting targets in health. Previous speakers have mentioned this. We are encouraged to do this by government. I'm not particularly happy with 'wet finger' estimates and Labour Force Surveys being used as the drivers but we have to start somewhere. We've heard the excuses and we can work with it. We are trying to do better in the industry. The work we are trying to do with Step Change and formation of a Step Change Occupational Health Steering Group is a way forward. I hope that we will be setting targets. But, each of us in our individual companies, and certainly in my own case in BP, needs to think about setting targets for ourselves. In BP, we have been working to a performance contract. It hasn't been easy. Three years ago when the first performance contract was demanded by my then line manager I thought 'Oh dear, now what'. It had to go on one side of A4. Everything goes on one side of A4 these days and no more than 4 bullets on a slide. My performance contract in Year 1 was no different. But over the years I have become used to it, and those on my team will know how much value we have got out of the performance contract. We have linked performance contract to terms, and to our own pay at times - and that focusses the mind somewhat! Inclusion of all stakeholders So, the services need to be holistic, broad and to include all the stakeholders. In the past the term 'medical' was used. What was 'medical'? It was some medics and the UKOOA MAC as it was called then. Health clearly has to include a lot more than that. Everyone is a stakeholder in their own health. There are many groups professional groups, employment groups - who have something very positive to add. I am pleased to say that the Step Change Initiative and the work group we are trying to pull together is going to be a broad church. It will include stakeholders who have traditionally not been included. This encompasses the NHS - a body that has picked up our problems year on year and dealt with them, with very little support from ourselves. We need to recognise their input in terms of a stakeholder. Non-holistic is not an option Along with previous speakers, I do not see that the classification 'occupational' is particularly useful in our environment. In fact, there is a professor in Singapore who runs the Faculty of 36 areas that we are moving into. Evidence-based practice and evidence-based medicine are the 'in terms', the buzz words in the learned journals. The offshore industry needs evidencebased practice, and we have heard about our lack of baselines. We are getting together the cross-industry health database and I appeal for volunteers. Those who want to work in a working group who are in this audience, please let me know because I need people to help us in that endeavour. Demographic challenges We have some interesting demographic challenges. The ageing workforce is mentioned frequently. In BP the average age of an offshore worker is about 46 now. We have small specialist teams formed from the more experienced older men. The so-called SWAT teams, that go fixing problems, tend to be older people. Thus right sizing and specialist teams bring with them their own health problems. Contractorisation has been mentioned at length and does give us issues around control. But I'd like to mention another challenge - the war for talent - getting the right people to come into the industry. Many of us, and BP is certainly no exception, are after increased production. We can't grow production as a global company unless we maintain the base of production we presently get out of the North Sea. We have to maintain that base and grow from it. To do so, we need people, and there is a war for talent. That is an area where health can positively contribute. It can be seen as a benefit. The health benefits you can provide for your employees can help win that war for talent. Sharing best practice This conference is going to be about sharing best practice. There is much that you are going to hear over the next two days which is all about sharing best practice. Hand arm vibration, Noise, Health planning - all of these things we share. As an industry the last five years has seen big changes. It has certainly seen some changes on OIAC (the Offshore Industry Advisory Committee). Echoing the words of previous speakers, we have moved much better together, we have had the public agreement of Shell and BP, we have had the public agreement of Roger (Spiller) and myself on matters during consultation on the ACOP. I think we all agree that the Regulations still got the wrong name being called 'First Aid', but the ACOP actually says 'health care', which is a very big move forward. Performance beyond compliance Looking at performance, we have heard that the industry under-reports. I would challenge that. But part of the problem has to be our regulatory systems. If we only use a regulatory system to manage performance perhaps that is not the right tool. Perhaps we need to look at other tools. We need to set up to manage beyond the compliance. Health is somewhat different in that, unlike safety, it goes beyond 'No (ill health)', it goes beyond zero. You can enhance health, which can be difficult in the safety arena and certainly in environment. One person's environmental enhancement is another's environmental destruction. We need to be more imaginative in our goal setting for continuous improvement. There are some signs that we are willing to do so. I recently took part in a workshop within BP where safety and health professionals worked together and, to my surprise, decided that we would work on 'wellness'. These were some serious hard-edged safety guys who I didn't think knew what wellness meant. But we are looking at a new paradigm to try to improve performance beyond the regulation, beyond compliance. Some of the work that was done during the consultation on medic training will be taken forward by the UKOOA Health Advisory Committee. We hope that will bring in a new era in medic training - more appropriate, more embracing, more about multi-skilling rather than multi-tasking, and recognising the importance of health promotion and matters such as hygiene. In my own company, we use our medic staff a great deal to deliver hygiene performance on our offshore installations. Managing challenges We have some real challenges to manage. Managing the fitness to work - especially at present, firefighter fitness - raises issues, e.g. if putting people into firefighting training exposes them to the risk of having a heart attack as a result of the exertion of the training. The date of knowledge has passed, we are not arguing whether it is bad for you or not. This isn't the same as mesothelioma and asbestos exposure - we know that if you push someone to climb up and down a ladder while carrying a hose etc they may well have a heart attack. This may not occur while they are doing the training but afterwards. If we know that this is I titled the final slide 'Plan, Do, Measure, Learn, Improve' - a simple mantra that we often quote as the way to fix things. Hopefully, I have included in my list some of the positive 37 a possibility, we have a duty of care to protect the individuals from it. That means needing to find a way of determining the underlying level of fitness. This is not easy, it can mean having to discriminate, but we have to do that against the background of the Disability Discrimination Act. We have been done no favours as an industry by not having the Disability Discrimination Act enacted offshore. Many of us in health management in the offshore industry have taken it on in broad principle. We are moving now to a position where, for example, we will look at stable diabetics being able to work offshore, we will look at not excluding epileptics who have been fit-free for many years, we will look at taking people who are on anti-depressant medication and where is no safety contra-indication for them being offshore. An SAS-type selection should not be applied before you are able to go offshore. There is an ageing workforce so be sensible. We have to deal with rehabilitation. Many of the companies are doing so as part of their case management. Sustainable development For those of you who follow things like sustainable development, I have included this as I think it may be one of the keys to the future. Triple bottom line economics Economic prosperity, Environmental quality and Social justice - are known to our industry. We have a Sustainable Development Group in BP who talk about this topic all the time, maintain websites, and run conferences. Despite the taxation, and despite the oil price's cyclical nature, I think we have been pretty good at economic prosperity. In relation to environmental quality, we have learnt how to play the green card. But what about social justice? I see social justice as the key. It's about what I said earlier, about being intolerant to occupational hazards, being intolerant of hurting people and of making them sick. It's about giving them justice. 38 T he Business of H ealth ♥ Good H ealth is Good Business ♥ Proactive versus Reactive ♥ Prof i l e putting the H i n HSE ♥ M anaging risk, understanding the complexities, clarity of processes ♥ V alue demonstration ♥ Good cost bad cost: getting to materiality ♥ M eaningful metrics ♥ M anaging to perform ♥ Setting targets ♥ The Performance Contract O ffshor e O ccupational H ealth ♥ Non holistic not an option ♥ Definition of Health ♥ Breadth of service provision ♥ All Stakeholders ♥ Demographic challenges ♥ A geing workforce ♥ Right sizing ♥ Contractorization ♥ War for Talent ♥ Performance beyond regulation, beyond compliance, setting the right goals f or continuous improvement Plan, D o, M easur e, L earn, Improve ♥ Evidence based practice ♥ Cross industry health database: Step Change ♥ Sharing best practice ♥ H A V S, Noise (NEM S), Health Planning ♥ M anaging challenges ♥ Fitness to Work, Disability, Rehabilitation ♥ New ACoP: Health care and first aid … ♥ Sustainable development ♥ Triple bottom line ♥Economic Prosperity, Environmental Quality and Social Justice 39 40 THE CHALLENGE OF SETTING OCCUPATIONAL HEALTH TARGETS Mr Stephen Williams, Step Change Support Team [Paper given on behalf of Paul Blakeley, Talisman (UK) Ltd.] The subject I have been asked to talk about is the challenge of setting occupational health targets. I think that I should first dispel some expectations that you may have. My paper is about the challenge of setting the targets - I don't have the answer. I'm not going to be able to tell you what the targets are. Also, in the light of the comments from previous speakers, it is perhaps also appropriate for me to dispel some other expectations you might have about Step Change; about who or what Step Change is. ð How are you going to measure it? ð Where is the data going to come from? ð What baseline should you be using? Step Change is not an organisation that is set up to solve the industry’s problems. Step Change was a commitment by the whole industry to improve safety so it basically includes all of you and all other people in the industry. It's all of us who are going to have to work the issues and develop the solutions. The small support team that I am part of will help to facilitate that process. Some of the things I will talk about this afternoon will be about the ways in which the support team can try to facilitate the process of setting of the targets and then the delivery against them. But, unfortunately, we are not going to be able to do it for you. The current reporting requirements are inadequate. We have heard how, according to the RIDDOR statistics, chickenpox is the issue for the offshore industry. Fortunately, I think none of us believe that is the real challenge. But then, what is the challenge? There are lots of data within companies but there is a lack of consolidated data for the industry. The figures that were mentioned by speakers earlier this afternoon - on musculoskeletal issues and others - are based on estimates of what we think are the main problems. But we lack the data. The same issues now apply for occupational health. The targets may have been set for us but what else do we need to do? The experience we had with Step Change suggests that the simple target is not sufficient. The challenge is to interpret the target and make it meaningful and something that we can work with. There is another problem with the targets which are set in 'RHS', and that is that they are measuring outcomes. These are occasions when things have gone wrong and we have observed a consequence. Yet we know that for many occupational illnesses there can be many years between the observable effects and the exposure that gave rise to them. If we wait until we have observable outcomes, we may build up another 10 or 15 years of unavoidable consequences that we don't want. Relying on the outcomes, therefore, is not sufficient. We need a mixture of both proactive and reactive measures. By proactive measures, I mean the type of measures that are sometimes referred to as leading indicators. These are things that we can monitor now to give advanced warning of future potential problems and allow corrective What's the challenge? Why is there a challenge for setting occupational health targets? They have been set for us, haven't they? 'Revitalising Health and Safety' (RHS) and 'Securing Health Together' (SHT) contain the targets - what else is there left to do apart from deliver against them? Well, I'd like to share with you a little of the experience of the Step Change in Safety initiative. This was started in 1997 with the target of improving safety by 50% over 3 years. Clear enough? It sounds clear enough until you get down to the detail of thinking through: ð What does it actually mean? ð 50% of what? 41 actions to be taken before the unwanted outcomes occur. group would need to understand the issues and find ways of sharing data. It would need very broad participation, not only from the partnering groups that are active within the industry, but also other ones, such as the National Health Service, that are outside the industry but who have a very real role to play. The Step Change support team has been asked to help co-ordinate the process. As I mentioned earlier, the support team can’t solve the challenges for the industry but it can help facilitate the process through the mechanisms that have been developed for engaging different participants and through the networks that enable greater workforce participation in the debate. Partnership The need for partnerships has been referred to several times this afternoon. Building effective partnerships will be a major part of the challenge. There have been major changes in the industry over the past five years or so. The demarcation lines between different parts of the industry are now very different from what they were. The sources of expertise and the people who can contribute to the debate and the solutions are now very varied. We need to engage all parties to participate in the discussion, to share their information, share their learning and insights to develop an effective way forward. What is the scope of work that the Occupational Health working group has set itself to do? The first activity is to develop common classification codes for occupational health. Many companies are already gathering occupational health data but do it in different ways. We need to agree a common way in which we can classify the information so that it can be shared and we can try to understand the causation as well as the outcomes. The need to work together and share information brings up the point of confidentiality, particularly with the medical issues, where there are obligations of confidentiality to the individuals. It's difficult to share the information and yet, if we are to understand what are the proactive things we should look for, we need to understand not only the outcomes to be avoided but also the causation that leads to them. This will need analysis of information about the circumstance that may have contributed to the outcome, not just the outcome itself. So there are confidentiality issues to be overcome to enable information to be shared whilst still protecting the confidentiality of personal information. There is also a debate on what kind of indicators can be used. What is the right mix of reactive and proactive indicators that can both inform our actions and engage people's interests? Which indicators will help to make the issues real and motivate effort to deliver the targets? How are we actually going to measure the data? What baselines are we going to use? I don't have the answers to these questions but they are part of the scope of work that the working group will be addressing over the forthcoming months. First steps What has the industry done to tackle these issues? There was a workshop on 11 January 2001. Fifty people from across the industry came together to talk about the challenges facing the industry and the processes for delivering on the targets that are contained in the RHS and SHT documents and the other targets from the HSE's Offshore Division. A database will probably be required to collect and handle the data. The issue of confidentiality of personal information will need to be considered. It is likely that the database will need to be held by a respected and trusted third party that can be independent and can address the confidentiality issues. There were three groups at the workshop: ð One considering the major hazards and what needs to be done to improve integrity; ð Another dealing with occupational safety; ð And, the third one on occupational health. I've got no answers to the OH challenges that have been identified, but I do have a timeline for how we are going to move forward. It is this last one that we are really addressing today and in the subsequent days of this conference. One of the main outcomes from that workgroup was the recognition that we need to have a broad-based working group to address the occupational health challenge. This The first part of the work will be a pilot study. A pilot is needed because we are not going to get it right first time. We are not going to get it right in all the details of the information that needs to be gathered. As we collect data we are 42 much measurable progress by 2004. Indeed, it is likely that, during the first couple of years of gathering data, there will be an increase in the amount of reported occupational health data. This is the final challenge that I want to highlight for setting the occupational health targets; the challenge of communicating what is being done. also going to develop additional insights into what the data means for the offshore industry and the actions that will be necessary to improve occupational health in the industry. The proposal is to gather data for 6 to 9 months through to the early part of 2002. Following analysis of the pilot study, the industry will then be in a position to: § evaluate the information, § finalise what the indicators should be, § confirm the way data will be collected, § confirm the ways of interpreting the data, § initiate full implementation during Q2 of 2002. It will be a challenge to communicate the actions being planned by the industry in a way that makes it clear that real progress is being achieved despite numbers that may appear to say the opposite. It may be difficult to explain that an increase in the reported occupational health data is actually a positive sign of the increased reporting rather than an indication of an increasing problem in occupational health. We have undertaken to develop this plan further and to report on progress to the Offshore Industry Advisory Committee (OIAC) in time for their July meeting. This milestone will help to maintain a sense of urgency and ensure that, although it's a 10-year programme for RHS, we start to take actions now. I think the plans being developed by the offshore industry provide a sound way forward to address the RHS challenges but - because of the time required to compensate for the initial lack of data and to get a good understanding of what are the real issues and challenges - we are going to have to take care to communicate very clearly: what it is that we are doing; why we are doing it; and why, initially, there may be an increase in the incidence of occupational health issues which are reported. Communication of progress. There is a recognised lack of reliable occupational health data. Without data it is difficult to know what the problem is and what can be done to improve performance. This leads to the ‘chicken and egg’ situation referred to earlier by Sandra (Caldwell); What do you do first, gather the information to establish a baseline or set the targets? Thank you for your attention. The way the UK offshore industry proposes to move forward is to accept the national improvement target and then collect data to establish the baseline and identify actions to deliver the required improvement. Once the database and data collection process have been put in place, further time will be required to build up the level and quality of the reporting. As a consequence, it will probably be 2003 before a reliable baseline will be established. It is not suggested that the industry waits until the baseline is available before developing an improvement programme. Preliminary actions to improve occupational health can be initiated in parallel with the pilot phase of the data collection activities. However, the delay in knowing what the baseline will be does have an important consequence for the industry. One of the RHS targets is for 50% of the improvement to be achieved halfway through the period, that is by 2004. With no existing baseline, it will be difficult to demonstrate 43 The Challenge What Challenge? • Current reporting requirements inadequate • Lack of data • What indicators to use?

Abstract This paper describes the general reasons for, and aims of the “National Inspection Projects” (NIPs) run by OSD over the past few years. The findings and conclusions are summarised from NIPs on the management and control of: noise, hazardous substances, asbestos, dermatitis, vibration and food hygiene. The findings were useful for considering best practices and in providing lessons for feedback to duty holders. The latter can include both strengths and weaknesses, so that the former can be built on and the latter corrected. The NIPs reveal where the Regulator may need to put more effort, whether by inspection, enforcement, or guidance. As well as ensuring compliance with health related legislation, the key aims of the HSE in the North Sea have therefore been to raise the profile of occupational health in the sector and to improve the assessment and control of health risks by line management. NIPs have been one element in achieving these aims. The nature of NIPs NIPs are focused inspections designed to examine a specific risk area in some depth. Various types of NIP can be devised, but those that have provided the information for this paper were targeted inspections examining the management and control of specific health risks using a structured questionnaire. Some of these NIPs had two parts: part for application at the duty holder’s onshore offices and part for application on one of their offshore installations. This allowed the application of company wide policies to be tested on selected installations. The questionnaires, while focusing inspection effort, were not intended to constrain the inspector, but provided a probe to open up the topic as necessary. Because no duty holder preparation was required, special visits were not necessary. Hence the NIPs were applied during normal preventive inspections over a period of one work-planning year. Introduction HSE’s early experience (Gardner, 1997) of the way occupational health was handled by offshore duty holders suggested that the sector were good at the person orientated aspects of occupational health such as fitness for work, provision of first-aid and medic support, and emergency response. However, the assessment and control of recognised and potential health risks in the workplace was less well developed and managed. There are various reasons for this. For instance, there was a view among many managers that “health” was a difficult topic that should be left to the health professionals. Line managers are also less likely to be involved in the investigation of cases of work-related ill health than they are in workplace accidents. The fact that work-related ill health may only appear years after the individual’s exposure to the causative agent(s), also means that managers are less likely to be faced with the results and costs of ill health arising from causes in the workplaces they currently manage. This latter effect may be exacerbated in the offshore sector by the selfselecting nature of the work and the potential “healthy worker” effect generated by the fitness for offshore work medical requirements (UKOOA, 2000). This latter effect may Since raising the profile of the topic was an important aim NIPs have rarely been standalone initiatives. For instance seminars, or other meetings, on the topic of interest were held during the periods over which NIPS on dermatitis, noise and HAV were run, and initiatives were supported by publications such as “Sound Solutions Offshore” (HSE, 1998a). Aims of the NIPs The principal aims of inspection are to influence duty holders to comply with legal provisions for the health safety and welfare of 47 though a limited number of upstream workers have been included in some epidemiological studies of refinery workers (Divine and Barron 1987; Schnatter et al. 1992; Divine and Hartman 2000 and references therein). A Norwegian prospective study of cancer among offshore workers has begun, and data from the Norwegian Petroleum Directorate (NPD) (Wiige 1996; NPD 2000) does include some information on chronic work-related conditions. The findings from the latter are broadly in-line with onshore findings in the UK (HSC, 2000); thus the main concerns relate to musculoskeletal diseases and stress. the workforce, and to encourage them to improve performance. The aims of individual NIPs varied within this envelope, but the basic aims of all of them were to raise the profile of the topic considered and to test compliance with the appropriate Regulations. In some cases (e.g. the asbestos NIP) an additional aim was to assist in assessing the potential impact of possible changes to Regulations. Testing compliance was mainly done by examining the adequacy of duty holders risk assessments and the controls put in place as a result of these. In most cases the NIP was constructed around the elements of a health and safety management system using the model of policy, organising, planning, measuring performance, and auditing and reviewing performance as described in HSE’s “Successful Health and Safety Management” (HSE, 1997) and the Oil Industry Advisory Committee publication “Management of occupational health risks in the offshore oil and gas industry” (OIAC, 1996). Most of the available published offshore data (HSE 2000; NPD 2000) relates to acute accident events collected through statutory reporting schemes. Some of these accidents/incidents may be the result of, or result in, chronic conditions, but it is not usually possible to judge this from the available reports. Studies of medical evacuation from offshore installations (Norman et al, 1988; HSE 1999) include diseases as well as accidents, but it is not necessarily clear whether or not they are work-related. Topics included in NIPS The topics covered by the 6 NIPS considered here were: noise (1994 - 1995 and again in 1999 - 2000), dermatitis (1996 - 1997) asbestos (1996 - 1997), COSHH (1997 1998), Hand Arm Vibration (HAV) risks (1998 - 1999) and food hygiene (1998 - 1999). In the absence of good risk data the HSE has approached the management of health risks offshore by “reading across” from known onshore risks (such as those from noise, vibrating tools, asbestos, etc.) and monitoring the assessment and management of these by offshore duty holders. This approach ties in well with the aim of improving occupational health management, but means that the NIPs discussed here have been designed to examine quite well established hazards. However, these could be regarded as a good test of how well health issues are managed at installation level on the basis that if well-known hazards are not well managed then newly emerging issues (such as stress) may be even further behind. Prioritising target topics for NIPs Various factors were taken into account when deciding on the target topic for individual NIPs. These included: the nature and extent of the hazard; HSE wide campaigns; the need to follow up compliance with new, or newly applied legislation; and general offshore intelligence from other sources. For a NIP to be worthwhile several of these factors usually needed to be significant. Campaign basis for NIPs Hazard basis for NIPs Over the past few years the HSE has run a major campaign to improve health risk management in the workplace under the banner “Good Health is Good Business” (GHGB). While the general aim of the campaign was to raise the profile of occupational health and improve its management, specific health risks were targeted each year. Many of the risks targeted were important offshore (e.g. noise, HAV, dermatitis, asbestos). The campaign generated publicity and guidance that was generally applicable to the offshore situation. There has been a range of reports on the general health of offshore workers (see for instance HSE 1994; Hahn 1987; HSE 1998; Wiige 1996; Horsley and MacKenzie 1997) and psychological and psychosocial aspects of offshore work (Lauridsen et al, 1991; Parkes 1998). However, published data on chronic work-related ill health in offshore workers is scarce. Thus we are not aware of any epidemiologicaI studies of the mortality/morbidity of offshore workers, 48 Hence it made sense to take the campaign plans into account when planning NIPs. Dermatitis Relatively few companies had specific policies on dermatitis, but over 70% of respondents carried out assessments that included dermatitis risk. However, these were often hazard assessments using the Material Safety Data Sheets (MSDSs) as a prompt for the use of PPE. In fact all the companies questioned used PPE as the main, or only method of controlling skin exposures. There were few examples of other methods such as substitution and better housekeeping. Compliance basis for NIPs Although no new health related legislation has been applied offshore for some years, certain existing onshore Regulations have been extended to the sector; notably The Control of Substances Hazardous to Health Regulations and The Noise at Work Regulations (NAWR). The need to check how well these were understood and being complied with was a factor in deciding to have NIPs on COSHH and noise. Also, HSE is committed to checking the impact of new, or newly applied, legislation, including post-implementation assessment of the costs and benefits. COSHH NIP was thus also designed to collect some information on implementation costs. Risks to the skin from hazardous substances were generally included in COSHH assessments, however, this meant that the issue was rarely addressed in detail. Barrier creams were in widespread use and around 50% of the companies had unwritten objectives concerning them. No other objectives or targets relating to dermatitis were noted. In some cases barrier creams appeared to be regarded as PPE. Intelligence needs A secondary, but sometimes important, reason for choosing a topic for a NIP was the need to gather intelligence in that area. An example was the NIP on noise where the information obtained was useful as part of the HSE regulatory impact study before extending the legislation offshore. About half the companies said that they used solvents or abrasives for hand cleaning. This appears to have been a misunderstanding, but some companies were using these inappropriate methods Other intelligence as a basis for NIPs Employees were comfortable to go to medics for advice and treatment of skin problems, but the level of formal reporting to the regulator did not reflect the number of visits to the medics. (Note: this was before the application of RIDDOR offshore). Intelligence from a range of sources also suggested that some topics justified closer inspection. An example was feedback from inspections which suggested that the risk assessment and control of vibration from hand tools needed improving Another example was our understanding of the views of offshore occupational health professionals in relation to noise on offshore installations. Training and awareness of employees to skin disorders was on an ad-hoc basis. Conclusions a) Companies that had carried out specific skin related risk assessments had benefited by developing more effective methods to prevent and control the risk. b) Duty holders needed to consider risk reduction methods other than PPE such as substitution, closed systems, mechanical aids and better housekeeping). c) The use of barrier creams required careful monitoring since, in some cases, they were regarded as a form of PPE hence giving a false sense of security. d) Work-related dermatitis seems to occur more often than it is reported to the Regulator. Findings Tables 1 (Annex 1) summarises the findings from the dermatitis, asbestos, COSHH and food hygiene NIPs, while Table 2 (Annex1) summarises those from the noise and HAV NIPs. Findings and conclusions from individual NIPs The findings from the NIPs were very detailed, so only selected points and the main conclusions are given below. 49 was a belief that the installation had been stripped some years before Management of asbestos seemed to be largely a reactive process. c) Few companies (24%) had ongoing programmes to survey and maintain asbestos on their installations. It is vital when surveys are done that the condition of any asbestos found is noted and acted on. d) The number of companies saying that they have made use of their Own expertise (71%) for information on measures to control asbestos was high compared with the number saying that say they had made asbestos assessments (47%). It is likely that this reflected expertise being used only on an ad hoc basis (e.g. when asbestos is found or suspected during ongoing work). Asbestos Findings 82% of companies questioned said that they still have asbestos on one or more of their installations. This was most commonly Chrysotile (white asbestos) but Amosite (brown asbestos) and Crocidolite (blue asbestos) were also widespread. Uses current at the time of the NIP included lagging (35%), ceiling tiles (35%), insulation boards ( 41%) and in items such as compressed asbestos fibre (CAF) gaskets, acoustic hoods, and brake and clutch linings. All but one of the companies had some sort of policy on asbestos and 82% had policies on asbestos substitution or were in the process of producing them. Only 18% of the companies had set specific objectives in relation to asbestos, but this lack of objectives had to be set against the fact that all the companies having asbestos on an their installations reported some action. 41% had programmes for removal of all asbestos on their Installations or selective removal where this was considered necessary. Control of Hazardous substances Findings All companies had a system in place to implement COSHH requirements, including some form of audit and review, or (in one case) were in the process of planning a system of audit and review. The majority (52%) of companies used COSHH re-assessments, or general HS&E audits, to trigger the review procedure All the companies had also carried out COSHH assessments, but, the quality of assessments was patchy with some being hazard assessments based on information in the MSDSs rather than risk assessment of the process using or producing the hazardous substance. External consultants had been, or were being, used to carry out full or part surveys on 71% of the Installations. In only 36% of the reports was the condition of the asbestos noted and most of the reports lacked recommendations. Most survey work seems to be triggered by finding suspect areas or word of mouth reports about asbestos. It was common for companies to appoint someone to “be responsible for” COSHH. However, they often had a range of other responsibilities to handle as well. Just over half (55%) of the installations had labeled asbestos containing materials. Most installations had no one trained in what to do if asbestos was damaged. However, awareness of asbestos hazards among employees offshore was quite high and concern low. But they were often not aware of its presence except when planned work on asbestos was going on. The most common activities assessed were related to drilling (e.g. mixing mud chemicals and related activities, work on the drill floor or in shaker houses and cleaning mud pits) and general workplace maintenance processes (e.g. painting; welding and cleaning. Conclusions A range of controls were reported as having been introduced post COSHH, suggesting that the Regulations had considerable impact. Outside consultants were widely used and generally thought to provide value for money. However, the information provided on costs was surprisingly sparse and were obviously loose estimates. For instance, the provision of LEV was generally considered to be expensive, a) It was likely that even if they are not aware of it most offshore companies will have asbestos on some of their installations, albeit in low hazard forms (e.g. brake and clutch linings). b) Asbestos was still present in structural features (e.g. ceiling tiles and wall boards) on some mobile installations were there 50 based company which was the subject of enforcement. but quoted costs ranged from £50,000 per rig to £500,000 on one installation, though the latter included some improvements to the general ventilation. The problems noted were at the contractor/client interface. Examples included: a lack of clarity over who had what responsibilities in emergencies such as an outbreak of food poisoning; maintenance of galley equipment not being seen as a priority by clients; and lack of client facilitation in getting catering company managers offshore to carry out audits, even when the clients required these. Economic pressures could also lead to a reduction in manning levels in hotel/catering staff on some installations. This was a cause of potential stress and a reduction in food hygiene. Another effect of this was a growing use of stewards as food handlers. While their training was good, this was not ideal because it potentially introduced a new risk of cross contamination. Eight companies had introduced new maintenance records as a result of the COSHH assessments, but some others had not added new LEV to their maintenance regimes. Some reported benefits of introducing COSHH included more efficient use of chemicals and reduction in stocks (up to 30% in one case). Also, 19% of the companies reported a reduced number of chemical incidents. Some companies had introduced new health surveillance, because of COSHH This ranged from simply monitoring the medic's log to periodic skin checks and 6 monthly lung function tests. However, there was much confusion in this area with many companies interpreting periodic offshore medicals as being appropriate health surveillance. Since temperature control regimens are vitally important to good food hygiene this was specifically targeted in the NIP as a “marker”. In general temperature controls were good though, though a range of relatively minor faults were noted on different installations. Examples included questions in individual cases on: the effectiveness of the methods used to clean thermometer probes between uses; the calibration of temperature probes and the provision of a back-up; and the effectiveness of checking the acceptability of incoming food. Conclusions a) There have been significant improvements as a result of COSHH being applied offshore but this is patchy. Overall the picture presented by the survey may be best summarised by inspectors’ opinions. No company presented an 'exemplary' assessment, six were considered 'satisfactory' and all the others required some rectification. b) The responsibility for implementing COSHH onshore and offshore is one of a number of responsibilities within staff portfolios, and this dilutes the effort given to COSHH. c) There were areas where improvement was required, particularly related to the standard of assessments (which were occasionally only hazard based) and the quality and understanding of health surveillance. Conclusions a) The FSMSs and HACCPs put in place by the catering companies were, with a single non-UK exception, very good. b) There were some problems of understaffing (often cost based) that could potentially result in stress among catering staff and a reduction in food hygiene. c) Most problems arose at the interface between contractor and client Safety Management Systems (e.g. difficulties in maintaining galley equipment and in getting Senior managers from catering offshore to carry out necessary audits). d) Temperature control (a critical element of food hygiene) was generally well addressed with only relatively minor and scattered faults being found. Food Hygiene Findings All but one of the catering companies had well developed food safety management systems (FSMSs) covering policy, aims and objectives, risk assessment - in this case HACCP (hazard and critical control point) assessments, organisation, performance measures and audit systems. The only exception was a non-UK 51 on the periodic UKOOA medicals for fitness to work offshore to provide audiometry. This could be building problems for the future since hearing damage by noise is usually most at an early age i.e. at the time when the periodic medicals are furthest apart. Noise Findings Perhaps the most interesting findings relate to the two noise NIPs. The first NIP (1994 – 1995) was carried out before the NAWR were applied offshore and most of the organisation on noise matters related to the requirements of the then Certifying Authorities (CAs). So at that time only about a third of the installations covered by the NIP had a policy specifically mentioning noise, but virtually all of them had regular surveys of area noise levels by the CAs. Also, half of them had other area surveys beyond the CAs requirements. The CAs generally used the area noise level standards given in Den/HSE guidance on design, construction and certification of offshore installations (DEN/HSE, 1990), but CA recommendations often seem to have been repeated over several years with little apparent action. Most companies were also using the action levels of the then onshore NAWR with the area noise surveys to identify areas where hearing protection had to be worn. Conclusions The general conclusion to the 1994- 1995 Noise NIP was that: “Three quarters of the reports indicated a need for the operator to take further action. A wide range of topics was noted, of which dose assessment and control of noise at source were prominent.” The overall conclusions from the 1999 – 20001 NIP on noise were: a) Compliance with the Noise at Work Regulations can be improved b) Duty holders should improve management of noise risks their c) Better ALARP demonstrations should be demanded by inspectors As might have been predicted, there were some marked differences between these pre- NAWR findings and the post-application of the NAWR offshore. d) Duty holder s should have better systems for providing education and information to their employees HAV Given that the NIP was carried out only 2 year after the NAWR was applied offshore there were some very positive findings. These included: the percentage of duty holders with policies and procedures on noise had doubled and others were developing; all but one had completed noise assessments and included exposure assessments; around 20% had identified further potential noise control measures; and some had targets for assessment and training. It was also evident that workforce awareness was higher than before. Findings and conclusions Early in the NIP it became apparent that although c 30% of the companies had some policy/assessment on HAV, little exposure assessment had been done, few controls put in place and little training given. Interestingly, c25% of the companies had some health surveillance in place, suggesting that health professionals were aware of the problem but that it had not become a matter for line management. Some 65 % had appointed a “Responsible person” for noise matters, but this person was not necessarily a “Competent person” and often had limited authority. Only 15% of respondents said they had seen at least one of HSE’s publications. The situation was such that of the 19 companies investigated inspectors judged that 15 had made little or no attempt to comply with the applicable legislation. Over the course of the NIP a meeting was held with industry representatives and the situation improved markedly. By the end of the year systems to Rather disappointing was the fact that the basic control measure was still delineation of hazard areas based on the action levels in the NAWR and the provision of PPE and a lack of recognition of the need under NAWR to reduce noise exposure as low as reasonably practicable. There was also much dependence 52 with - they are simply stand-alone results. The findings do, however, provide a benchmark for future follow up. assess the risks (including measuring or otherwise assessing the vibration levels of equipment), purchasing new lower vibration tools and controls (e.g. limiting and recording the time spent using vibrating tools) were becoming widespread. The effects of these initiatives are the subjects of other papers for this conference. Even with these provisos some general trends can be discerned. 1 A number of the findings would suggest that the more specific (if not prescriptive) the legislation the better the assessment and control. This is best illustrated by comparing the extreme cases of food hygiene and HAV. In the former the detailed onshore legislation does not apply offshore, but is used as the standard for enforcing offshore provisions; in the case of HAV only the general provisions of the Health and Safety at Work Act 1974 and the Management of Health and Safety at Work Regulations 1999 apply and assessment and control regimes were not well developed. Comparison of the situation before and after the application of the Noise at Work Regulations offshore highlights the same point. A somewhat unexpected conclusion was that the use of hand held vibrating tools was much more widespread than had been thought before the survey. Among the companies surveyed, which included contractors, about 1800 workers were reported as using hand held vibrating equipment. Scaling this up across the sector would suggest 2000-3000 workers are regularly exposed to the risk of HAV. The most frequently used equipment known to have high vibration levels were grinders, needle guns, impact wrenches, air drills and chipping hammers. Also reported in use less were, nibblers, scrabblers, air drills, jigsaws, a floor polishing machine and an engraving pen. Discussion 2 There were few targets or objectives set on health matters at the installation level and few specific performance measures in relation to the topics covered. In considering the findings from NIPs we need to bear in mind the nature of the exercise. 1 The NIPs described were not statistically based surveys designed to provide scientific data. The cover achieved was, however, reasonable, with returns in the range of c 28 - 40% of duty holders and c 10 - 19% of manned installations. (In the case of the food hygiene NIP all the then extant catering companies were included and the number of occasions when the NIP was applied to each of them was proportionate to the scale of their presence in the North Sea.) 3 There was considerable confusion about health surveillance with many duty holders quoting the annual offshore medicals as their health surveillance. This is unlikely to be satisfactory for conditions such as dermatitis that can develop rapidly or for the early detection of hearing loss in younger workers. 4 It was evident that there was still some confusion between hazard and risk as a basis for COSHH assessments. Examples were the existence of some substance based COSHH assessments (essentially using the MSDS without reference to the way the material was used) and the fact that most inspectors thought that one of the strongest elements of the way duty holders handled COSHH was in the computerisation of data. 2 The NIPs are a snapshot of an ongoing process - stills from a moving picture. Hence some of the findings were already becoming out of date by the end of the year the individual NIPs were applied in - this was particularly the case with HAV. Indeed the NIPs, with other activities, contributed to the process of change, for example they often led to companies re-examining the way they approached the topic being examined and on several occasions to formal enforcement activity on the part of inspectors. 5 The NIPs suggest a quite heavy reliance on PPE for control - particularly with respect to hazardous substances (including skin protection) and noise. General inspection experience supports this. Many exposures offshore are of short duration and PPE may be a quite satisfactory method of control. However, PPE use can lead to a false sense 3 Except in the case of the two NIPs on noise there was nothing to compare the findings 53 Horsley, H., and MacKenzie, I. G., 1997 “Lifestyle Survey Amongst North Sea Oil Workers”, Proceedings of the Occupational Health Offshore Conference: Aberdeen 26 - 28 March 1996, HSE Offshore Technology Report, HSE Books, p161 (ISBN 0 - 7176 1423 - 9). of security - after all the cause of the risk is still there. An extreme example, noted during the NIP on dermatitis, was the use of barrier creams as if they were PPE. 6 Some of HSE guidance had not really penetrated – for instance there seemed to be little awareness of HSE guidance on HAV. HSC 2000 “Health and Safety Statistics 1999/2000” HSE Books (ISBN 0 – 7176 – 1867 – 6). Conclusion The NIPs have provided good intelligence for inspection purposes in highlighting deficiencies in the management of various health issues and provide a benchmark for future comparisons.

At the 1996 Offshore Occupational Health Conference a number of speakers commented on the “Cinderella status” of the topic compared with safety (HSE 1997a). With other information (e.g. from general inspection) the findings from the NIPs suggest that this is changing and that the management of occupational health matters at installation level has improved in the last five years. The targets given in the recently published long-term occupational health strategy for England, Scotland and Wales (HSC 2000a) should provide further impetus for improvement.

The generic table is modified to reflect the needs of each business unit and it then becomes the BU Specific Planning Matrix, which is used by the site health planning team to develop their needs on a three year rolling timeline. Abstract BP commitment to Health, Safety and Environment (HSE) performance is simply stated: No accidents; No harm to people; No damage to the environment. Everyone who works for BP anywhere is responsible for getting HSE right and BP’s business plans include measurable HSE targets. Therefore where ever BP operates or whenever it enters into new and different ventures and countries; management systems for implementing the relevant HSE programmes, procedures and legislative requirements should be either already in place or being initiated. In addition, seven specialist appendices ranging from Occupational Hygiene to Stress Management have also been prepared as further guidance. The pack also contains an introductory brochure, several health planning graphics, an outline of a health planning seminar or workshop and reference materials. Introduction Normally, of the three HSE elements, ‘Health’ is the least well understood and resourced, and is therefore given the least attention. To help ensure that health aspects in BP Exploration (BPX) are initially identified, easily understood and then addressed in an ongoing and suitable, sufficient and timely manner, a Health Planning process has been developed. Safe and efficient operations depend on people and BP attempts to operate its facilities in a way that minimises health risks to employees, contractors and the community, and encourages people to adopt a healthy lifestyle. Thus enhancing operations integrity, BP’s reputation and productivity, and establishing a firm foundation for growth. Health encompasses a spectrum of states ranging from extremes of premature death to optimum health. Preventing work related ill health is a recognised management responsibility and is specifically stated in the Company HSE Commitment of “No Harm to People....”. There is also potential to achieve distinctive performance by addressing positive prevention and health enhancement. Good health benefits the individual and plays an integral part in delivering successful business performance by minimising loss and maximising gain. The concept of health planning is important for three reasons: • It is based on examined practice; • It is an effective way of managing the business issues of health; • It shares a common language with that of safety. The Health Planning Resource Pack (BP) was developed as a practical tool for implementing health planning. It also works well as a marketing vehicle or device to raise the profile of health as a business performance issue. Each pack contains an overview of the health planning process and offers a number of tools to assist Business Units (BU’s) in constructing their own specific health plan. The principal planning tool is a Generic Planning Matrix or The full BP management HSE expectations are given in the internal guidelines ‘getting HSE right’ (BP, 1999a) and the management health strategy in ‘getting Health right’ (BP, 1999b). The three elements of health management being designated as: 61 • Prevention; • Management; • Promotion. 4. Audit & Monitoring - Regular review, audit and surveillance programmes to verify and provide assurance of performance against expectations. 5. Data Management - Methods adopted should be simple but provide for accurate and efficient recording and speedy retrieval of information. The ‘Health Planning Resource Pack’, if utilised fully and correctly, will ensure that all three are carried out correctly and effectively. Health Planning Resource Pack 6. Accident Investigation - Health input as part of an interdisciplinary team approach to accident awareness and prevention. The Resource Pack contains planning sections set out as generic templates, which consist of tables with columns, entitled; 7. Compliance - Familiarisation with all new and current health and safety legislation. 8. External Communication & Networking Liaison with regulatory bodies, industry associations, health professionals etc. Expectations - Set objectives. Activities objective - Task(s) required to achieve the The pack also contains specialist appendices prepared to assist in planning key health risk areas: Outcome - Goal or deliverable. Responsible Persons - Who is accountable for delivery. • • • • • • • Both the core elements and the specialist Appendices use the same format. Prevention of Injury and Ill Health This forms the first core element of the health planning process. It utilises an established risk management approach; risk assessment, planned intervention and evaluation by audit. The plan includes contingencies for the following: Occupational Hygiene Ergonomics Environmental Health Stress Projects Normally Unmanned Installations (NUI’s) Indoor Working Environments Developments for further specialist planning appendices are dealt with on request. Management of Injury and Illness The second core element ensures that sick or injured personnel are managed to ensure costeffective utilisation of health services and a prompt and safe return to work. First aid and emergency care are included in this element, which is sub-divided into: 1. Evaluation & Control - The identification, measurement and appraisal of risk. An ability to control the physical, chemical and biological factors arising in or from the workplace which may effect the health or well -being of those at work, or those in the community. 1. Primary Care - Provision of treatment facilities for immediate care and arrangements for first aid and resuscitation where medical facilities are remote. 2. Assessment of Fitness to Work Recognition and diagnosis of occupational medical conditions and the early stages of occupational disease. 2. Oil Industry Specific - Development of specialist expertise to cope with emergencies unique to the industry. Participation in developing contingency plans for major disasters in collaboration with external emergency services. 3. Projects - Minimise health risks by the application of sound standard, procedures and management systems for the design, procurement, construction and start up of BPX facilities. 3. Management & Administration of Ill Health - Provision of information, advice or 62 counselling and referrals of illness. Assessment of employees’ health following absence from work and re-settlement of sick or injured worker in collaboration with other health professionals and management. Health Planning Workshops Health planning is a process by which the BPX Health Team along with key HSE and management BU personnel can work together to achieve the timely production of a business specific health plan. The objective being to deliver a draft plan with clear deliverables and performance measures. Resource management, budget and time can be included if required. Plans should then be reviewed regularly i.e. on a quarterly basis. 4. Rehabilitation - Manage return to work. Medical pension and medical early retirement, and consultation with specialists. Health Promotion Health Management Health promotion focuses on significant modifiable health factors and aims to help employees help themselves. Quality assured health promotion is one of the few tools for managing the health of the ageing workforce where the diseases of lifestyle are increasingly important. Management of health risk is a continuous process, and it is hoped that line managers and HSE personnel will use the BPX Health Planning Resource Pack to identify relevant health protection operating procedures, assessment forms and BP best practice documents. In addition, occupational medicine and hygiene expertise will be harnessed as necessary to help ensure not only legislative compliance and with the full requirements of BP “getting HSE right” (BP, 1999a) and ‘getting Health right’ expectations (BP, 1999b), but most importantly, active protection of the health of the workforce and local community will be achieved. 1. Marketing Health - Promote a healthy lifestyle at work and at home. Deliver a strategic quality assured risk based programme with the emphasis on a holistic approach to wellness including physical, psychological and social well-being. 2. Health Screening - Programmes include a variety of screening interventions ranging from questionnaires to consultations with health professionals. Focus is on the major health risks: coronary heart disease, stroke, stress and cancers. These risks are associated with modifiable lifestyle factors: smoking, alcohol, diet and exercise. Health Performance Improvement In the BP HSE expectations (BP, 1999a) it states that the Company will periodically assess the implementation of and compliance with the expectations to assure employees and stakeholders that management processes are in place and working effectively. It will then use such information to improve its performance and processes. Furthermore, in the first element of the HSE Management System Framework it specifically states that leaders should continuously strive to improve HSE performance. 3. Needs Based Campaigns - Reinforcing the maxim that ‘Good Health is Good Business’ through the use of health promotion campaigns based on identifiable needs. Links maintained with occupational health hazards where relevant, such as noise, stress and musculoskeletal disorders. Cost effective campaigns to be delivered through the range of resources available via the ‘Alive and Kicking’ project (additional material is contained within the pack). Businesses are therefore recommended to prepare a one-page summary of their health plan these to focus on the key health risks, opportunities and resulting performance measures can then form part of their HSE performance contracts. 4. Raising Local Health Profile - Engaging in health award campaigns e.g. Health at Work Award Schemes. Utilising campaigns to maintain a longer term focus on health awareness. Participation in local charitable events. BP now requires all business units to develop and have a Health Plan in place. The next stage, already in progress, is to develop an electronic version of the process. 63 Conclusion References The Health and Safety Executive in the United Kingdom use the slogan “Good Health is Good Business”. BP states that “Health is an Integral Part of Business Activity” and we hope that with the correct use of the planning tool described within, that this will be true for all BP Exploration activities.

Again, people and time above certain vibration levels. To me those are the sorts of ways we need to be thinking for performance standards. They are some examples of the way we can think of performance standards that we could measure and hopefully see an improvement as time goes by, making due allowances for decreases in numbers of people. Is there anything in the work that either of you two have come across that involves something like that? Question - Chris Hopson, Upstream Newspaper I wonder if I could ask Steve Williams just to comment a little bit about worker involvement in offshore safety, in particular where the Changing Minds initiative has got to. I thought that leaflet was due to be produced before Christmas. Perhaps you could just comment a bit on that? Answer – Mr Stephen Williams, Step Change Support Team The Changing Minds document has been released. Copies are available for people who want them and it's publicised via the flyer and the website, so if you want a copy let me know and you can have a copy. It was published at the end of last year, about November I think. Answer - Lindsay Ross, BP Yes, well certainly in the area of noise Kevin. We have developed systems that have helped produce those performance standards now. There's the Noise Exposure Management system which can deliver quite a lot of data on people’s exposure levels above first and second action levels etc, the amount of training that's on the go and all the rest of it. We have built them into some of our business plans already. On the hand arm vibration side we're just on the verge of launching a management system for that, so as a follow on to that we would obviously look at putting in some performance levels there as well. The hygiene lends itself to developing these key performance indicators and we have got a number of them spread through our business plans. About workforce involvement in it. Sticking with the occupational health side because that's what we're debating today, there is definitely a need to get workforce involvement in agreeing the targets that we should be setting. The way that we're proposing to do this is through three work groups that are being established. There is one for each of the three major target areas for the industry; one being occupational health, another occupational safety and the third the major hazards. Those work groups will involve a broad spread of stakeholders to put together a proposal for both the indicators and the targets. That will be consolidated into a consultation document which will then be sent out to trade associations, the various networks and other stakeholders to get feedback. This will allow consolidation into an overall position which we hope will reflect all parts of the industry and which can be taken to OIAC in July. Answer – Mr Stephen Williams, Step Change Support Team I can't really add to that in that the performance standards will tend to be issues for individual companies and, whereas within the networking and the working together as an industry we're sharing that information, ultimately the decisions of what individual companies implement will be a decision for those companies. Question - Kevin O'Donnell, Offshore Safety Division HSE A question possibly for Stephen but certainly for Lindsay. There's obviously quite a lot of detail behind the occupational health plan that you explained, but is there anything in it that might work towards performance standards? Some things I've got in my mind are noise and vibration. Noise - for example, the number of people, or the decrease in exposure in people offshore to first and second action levels or specific noise levels. Or, for example, hand Answer - Dr Jim Keech, BP, Chairman of UKOOA HAC As one of the architects I suppose of the idea of a coherent cross industry database - as it was myself that facilitated the workshop that decided that that was a way forward - we are very clear that, with a lack of baseline and a lack of clear sharing of the data that is out there already, it is very difficult to set realistic targets. I think we were surprised at the way 65 material to their own benefit and development of trust is absolutely essential. that that particular working group at the workshop on 11 January actually came together. Despite being from across the industry and with many different stakeholder groups represented, there was good agreement as to what the way forward was. a Answer - Dr Jim Keech, BP, Chairman of UKOOA HAC Yes I'd like to respond on the confidentiality issue. Although I appreciate the sentiment and certainly it is the intent to use the database in a proper and appropriate manner, it is a sensitive issue. If we are to use that database in a way that is going to allow us to track back - maybe if in years to come we find that there was some particular exposure, some particular event that may not even come under the general hygienelike exposure classification - then we have got to solve the problem around names, around being able to link back. As a country we've got some good stuff to go on. There are some cross-industry databases already out there in terms of reporting occupational disease. Occupational physicians reporting activity (OPERA) has just produced a report that's been published and there's some interesting stuff in there. We hope, with the guidance of the very people that have produced those databases, to try and do something equivalent for the offshore industry. The specifics of the performance indicators will have to wait until we have actually got some baseline data to work with. Meanwhile, certainly individual companies I know are already working these issues. If I take our own example we have focused, for instance on dealing with a particular problem - low back pain. By having a classification system in place, we were able to see what our low back pain figures actually were. In that performance contract I mentioned, we looked to how could we contribute, what could we do, and the target we set was to reduce the severity index, to reduce the days lost per case of low back pain. Last year we paid out on the gain share on the basis that we had managed our stretch target of reducing that not just by the 25% that we set out in the beginning of the year, but by 30%. My team benefited around this time of the year when our bonus gets paid. I'm sure mine is not the only company that is able to set specific targets and I think when we get the database together, then we as an industry can start to look at what those targets might be. To take the point about contractors, I would hope - well I can hand on heart say as far as BP’s concerned - you don't sit for 12 months without any contact. However, I appreciate that for many of the contractor organisations they frankly don't have that level of follow-up. I think as we move together and as we share with our contractor colleagues then standards, new standards in case management, are being introduced into many of the contractor organisations. It's not going to happen overnight and I'm sure you can give me evidence and examples of horror stories. But I think it is moving and there is a great deal more social justice being introduced into the industry than clearly ever was before. Comment - Jake Molloy - OILC Offshore Union Firstly I'd just like to say I support everything that you're saying here today - commendable, very laudable sentiments. However I think you will continue to struggle significantly in certain areas, unless something tangible, demonstrable is done for the offshore workforce as a whole. You talked about under reporting. I have absolutely no doubt in my own mind that there is significant under reporting, wholly and simply because of the financial penalties which individuals incur simply by going sick. They will harbour and hide illnesses and conditions in order to avoid loss of income. That's a simple plain fact. Care is significantly lacking, significantly lacking. People, members of this organisation and others in this room, have been sitting effectively disabled for year upon year with no contact from their employers, no support, no backup, no rehabilitation. That brings me to my final point, Jim. If you want evidence-based practice put my name on your list. I will provide you with more evidence than you could ever imagine because we don't have a problem with confidentiality, simply because the membership trust us to use that Comment - Jake Molloy, OILC Offshore Union Could I just say one thing there. We are moving in actual fact. Sick pay has gone up from £50 to £60 per week, so thank you. Comments – Dr Ron Gardner, HSE Could I make a couple of comments there. First of all, on confidentiality in this context. The sort of database that's being developed. Confidentiality is important to individual companies, but what I would hope to see, whether the data is confidential or not, is that it’s accurate, that it's presented and that in 66 have any performance indicators in there and yet some are very obvious. Have we actually reduced exposure? Many companies have put LEV in (Local Exhaust Ventilation) and yet they didn't check how effective it was and that's necessary under the regulations. Is it every 14 months? In fact they've not put any system in place to do that, yet it was a very obvious measure of performance. So perhaps I start from a slightly lower baseline than you are thinking of. Does that answer your question? particular it gives trends once we get over some period of time. It's not just for seeing how well you do against your baseline but it can give you early warning of problems that may be developing. I think that's absolutely key to that sort of database. The other point is on the reporting or under reporting. Jim and I had various discussions about this. We have some disagreement about this. In some areas I think there is under reporting and I'm pretty certain RIDDOR is under reported, but that's not just offshore but onshore as well. There are all sorts of reasons for that. In some cases it's misunderstanding, in some cases it may be purposeful, I don't know. In other cases it's the regulation itself, it’s not particularly useful for the offshore world. I think that's something that as regulators we need to look at and think about, just whether RIDDOR is really fit for purpose. I think that comes very squarely under the Compliance programme of Securing Health Together. Question - Dr Ron Gardner, HSE A question for Lindsay and Jim really. When/how long's this programme been in place? What I didn't pick up (maybe trying to read at an angle doesn't help), is how do you audit it? How do you check with the business units how well they're doing or do they do that themselves? Is there any central view of this? Answer – Dr Jim Keech, BP, Chairman of UKOOA HAC The Health summary sheet went into all the exploration business units globally, who were required to submit a summary of their health plan. We managed to get all the business units in our area to submit. It was remarkable when we examined the health risk matrices that were behind those, how right across the globe we had the same issues; psychological health, stress, musculoskeletal injury and disease were top right hand issues. That was common whether it was Venezuela, Angola or Bruce, Brae or Miller. It was that summary that was in there. Different business units have chosen different routes to get to the summary. We have taken exception when we have found that all they've got is a summary because frankly that's not good enough. Question – Mr Graham Cowling, Acoustic Technology Ltd A question for Dr. Gardner. Your presentation indicated that if we're talking about a target, that the real target actually is the condition of ALARP (as low as reasonably practicable). How does that sit with the fact that perhaps the ALARP situation may mean that different companies set different targets? How would you resolve them having different targets? Answer – Dr Ron Gardner, HSE I have no great difficulty with different targets. I'd be happy if there were the targets! I'm starting from that sort of baseline. Gradually over a period of time with sharing of practice, with sharing of best practice, with sharing of such targets, I think those targets would equalise. It's getting those targets and the indicators there in the first place and sharing them. To be fair a lot of companies do have all sorts of targets on health and some have performance measures, but often they're not shared and I think that's something that this conference could be very useful for and something certainly the Step Change initiative would be very useful for. Comment – Lindsay Ross, BP We do actually internally audit as well. We have an audit group within BP in HSE, getting HSE right. The group go round and obviously they look for the detail behind the summary health plans, making sure that they're meeting the company expectations. Question – Dr Ron Gardner, HSE Are lessons from those passed back generally across the other units as well? Again coming back to best practice. People sometimes lack a bit of imagination I think in setting targets or indeed performance measures. I was very startled at a different example to noise, but with COSHH. A large number of companies have done some good work since COSHH was applied. Very few Answer – Lindsay Ross, BP I think we'll be able to facilitate that much better once we get it onto a shared electronic basis. At the moment it's hard copy and each keep their own systems so that limits the 67 works very well, we just take the one we have, interface it with the one that the client has, and let them both perhaps exhibit their best points or work together effectively. So thank you for answering the question. amount of sharing that goes on. As an Occupational Health team we can obviously help facilitate that sharing as well. Where we see a good performance measure somewhere we can maybe suggest that to another business unit that has similar risk scenarios, so there is a degree of sharing that goes on. Comment - Dr Ron Gardner, HSE Dennis, it is interesting that you mentioned interface documents. I had experience of looking at safety management systems, when I first joined OSD, before getting into the health bit. It was very interesting that the health topics were often the ones that didn't get covered particularly well in the interface document. If there is going to be a hole anywhere it's often related to something to do with health. The sort of message you're giving me now is quite encouraging. If either side can provide the management system to cover some of these topics, that’s excellent. But it was an area, certainly historically, where there was often a hole in the interface. Question - Dennis Krahn, International Association of Drilling Contractors A question for Jim Keech. I'm sorry I didn't think of the question after Malcolm Brinded's presentation, but it was during the coffee break that I was having a discussion with some of my members. There was the implication in Malcolm's presentation that their systems were superior to those that hadn't heard the gospel yet. So those that had installations that weren't company installations were perhaps inferior, implied maybe but you could draw that conclusion. Now some of my members tell me that they have very good systems and so my question is this. Do you think that you are concentrating on your own systems and may not be able to recognise those of the contractors who have very good systems? And if they have very good systems, could you leave them functioning like they are or maybe even in an ideal world learn from them by sharing best practice? Comment – Mr Taf Powell, HSE I've been away from Offshore Division for a while. I came back last summer and have just a couple of observations that I'll share with you. First of all I've not seen Step Change. It was invented, or discovered while I was away, but it certainly has impressed me in a sense that it has joined up a lot of people under a common enterprise. It started with senior leadership and that was very good. However, one thing I thought about Step Change was that perhaps some of the leading indicators tended to be on a softer side, things that we were doing well as a good leading indicator perhaps rather than measuring some of the precursor failures, where you get a lot of data about trends and where that might be taking you. If there was one extrapolation into the health area where you need to develop leading indicators clearly to make a difference in the future, is that some of those leading indicators probably do need to be the harder side, where things are going wrong, of no consequence maybe, but nevertheless not just where we're showing signs of doing things well like training, worker involvement and so on. Answer - Dr Jim Keech, BP, Chairman of UKOOA HAC I assure you we do, and I would take the example of the drilling contractor on the Faeroes operation, who demonstrated an excellent health surveillance scheme. This is a great model and a model that certainly I will be adopting in BP where it makes sense. I think it has been alluded to already, the confusion that there has been in an industry that has had a fitness-to-work medical which has nothing to do with health surveillance. What we saw with that particular drilling contractor was an excellent attempt at managing the whole issue of health surveillance. I don't think that necessarily we are superior because we've got better resources, because we're big operators. We're learning all the time and I'm sure Malcolm was not suggesting that we have nothing to learn from your members. That's certainly not the case. Comment – Mr Stephen Williams, Step Change Support Team Leading indicators are something which have incredible power and benefit to help us move forward, providing they're used correctly. There are a lot of ways, a lot of pitfalls in their use, one of which is measuring something which we're already doing well in that the main value for leading performance indicators to me Comment - Dennis Krahn, International Association of Drilling Contractors Thank you for that. It just came to my mind that for safety management systems we have an interfacing document. That was what was at the back of my mind. If we find something that 68 stinging papers to people who then don't publish them so I'll have to take my opportunity. First off yes, we are very good as an industry at measuring what we didn't want to have happened and this gives us a very negative view of safety which is very often unhelpful when it comes to improving performance. The same can be said of health as well. is to actually drive the improvement process and therefore they need to be measuring something which you feel is relevant for improving performance and something which you could do better. Additional guidance is being developed on leading performance indicators, both for safety and for health. The draft consultation document for that is being prepared at the moment. If there are people who would like to obtain copies of that, during April we're basically trying to seek input on the guidance we're giving for the more effective use of Leading Performance Indicators, to try and counter the shortcomings and potential pitfalls and get more effective use. I think they are potentially very powerful vehicles for both engagement and workforce participation in identifying what the important issues are and then having identified them, are giving recognition for where there is improvement in performance on those. Two things - one is that many of us, as health professionals, safety professionals etc., seem to have forgotten all that statistics and epidemiology as too difficult. It was in a book that we probably didn't read and how often do we actually use the techniques of the analysis of variance, of determining whether a significant change has actually happened? It is in all the scientific literature, it's there but do I ever see it in health and safety data in the industry? No, so a lot of the time we chase our tails on things that have happened by chance. We've ignored those techniques in our pursuit of the Holy Grail. We could learn something from the marketers. We could learn something from the social scientists. We could learn from those people that sell us things we never knew we wanted by analysing their questionnaires in a very clever way. I mean, I would love to know how they keep selling new boxes of soap powder with no real significant difference and it still just cleans your kit, but they do. So why can't we learn from those folks as to how to produce leading indicators, how to interpret data to make some meaningful change? Comment - Dennis Krahn, International Association of Drilling Contractors IADC was pretty instrumental in leading indicators. Charlie Mearns was the one that led intellectually on that. The inspiration was that in the beginning of a contract process we would often be asked by the clients about our lost time injury frequency and of course they have a right to know that and you gather statistics and do an excellent job. But it was not what they were doing offshore with their workforce to inspire better performance, so it didn't feel right. It was backward looking and measured failure etc so we wanted to get away from that. Now you're quite right in that they are imprecise and that they tend to measure what you're already doing well. However, I think Stephen is right in the inspirational bit that they have for your company and for your workforce - you know the positive feeling and the desire to excel and perform well instead of the kind of negative feeling that comes with things that happen so that's how we use and how we think of those. Comment – Dr Kathryn Mearns, University of Aberdeen Can I say something as a social scientist who has been working with the industry. We've just completed a benchmarking study where we've looked at a number of different leading indicators and we've been using some of the statistical techniques you've just mentioned in terms of regressions and analysis of variance. There is a lot of value in that, in understanding actual relationships between variables and what has the impact, which variables have an impact on another. So I would very much support your comments. For lots of Leading Performance Indicators we don’t have the right metrics yet. We know what we want to talk about but we don’t yet know how to measure progress quite so well. Comment - Dennis Krahn, International Association of Drilling Contractors It's visible when I go round to my members' offices. Now I see fruit out. It brightens up the place and is an indication of healthy eating. I see people having competitions at lunchtime, riding stationary bicycles for charity. In terms of leading indicators for health performance, Comment – Dr Jim Keech, BP, Chairman of UKOOA HAC I would just like to share some thoughts on the leading indicator argument because it's something that I've been contributing some 69 statistical association on its own means nothing, unless you've actually got some mechanism that makes the association sensible. But to be honest I see far too much scientific work that doesn't have that. It just has the statistics. This is just a health warning. If you are going to use it, make sure you understand. Have your hypothesis first and test it. Don't come up with lots of associations. It just confuses everybody. hopefully that will feed into our ideas about how to do what Jim said, market safety. Safety for some people I've heard say, offshore at least for the workers, it's kind of a burden now. We need to take some of these ideas which health seems to have and capture those for how to make safety fun and interesting and get people to contribute with the same kind of enthusiasm. Comment - Dr Ron Gardner, HSE Can I slightly play devil's advocate with a word of caution here. I agree with Jim in the sense that you need a very scientific approach to this. But I spent a fair part of my life using things like regression, analysis of variance and I see a lot of work now which worries me. There is lots of data. The world is awash with data and people mine that data rather unthinkingly and they come up with associations like ‘the analysis of variance supports an association between X and Y’ and you look at it and you think how on earth can they be associated? A Comment – Dr Jim Keech, BP, Chairman of UKOOA HAC My appeal was not for associations necessarily, but understanding the difference between association, correlation and causation. As some of my poor health and safety colleagues know I am likely to send out, I think it’s the Bradford Hill Postulates (I see Nerys nodding). I send those around the globe every now and again just to keep them on the right tracks. 70 DAY 2 MORNING SESSION SESSION THEME – OCCUPATIONAL HEALTH IN THE OFFSHORE DESIGN PROCESS 71 72 OCCUPATIONAL HEALTH IN THE ENGINEERING PHASE OF OFFSHORE DEVELOPMENT PROJECTS – LEGISLATIVE BASIS AND EXPERIENCE FROM PROJECT AUDITING IN NORWAY Mr Sigvart Zachariassen, Mrs Anne Myhrvold, Norwegian Petroleum Directorate, Stavanger, Norway Why focusing the engineering phase? Abstract Many employees on offshore oil and gas installations have to rely on personal protective equipment to avoid work related diseases. This is not recognised as a proper prevention strategy. High noise levels and bad ergonomic solutions are often deeply grounded in the design of the installation and type and arrangement of machinery. Technical modifications in order to achieve significant reduction of exposure and risk levels are difficult to achieve and expensive to perform. Occupational health achievements seem not to fit well into traditional cost benefit based decision-making. Based on audits and follow up activity mainly directed at occupational health conditions in the operating phase of offshore installations through the eighties and beginning of the nineties, we realised several characteristics of the existing occupational health conditions: • • The Norwegian Petroleum Directorate (NPD) has since 1995 enforced an occupational health legislation that focus in particular on a systematic approach to the design and engineering phase in offshore development projects. The NPD has followed most of the recent offshore projects closely by audits and verifications. • • The industry has followed up the legislative initiative by developing a specific standard for how to deal with occupational health aspects in the engineering phase. Occupational overexposure and work related illnesses/injuries due to poor arrangements in areas and poor design of machines and equipment Occupational health requirements not regarded as hardcore technical requirement and consequently not identified and followed up through formalised management systems Modification work to rectify bad occupational health conditions in the operating phase is expensive and troublesome Weaknesses are copied to new installations These observations gradually led to a change in focus from the operating phase to the engineering phase. The last years the NPD have closely followed most of the main offshore development projects from an occupational health point of view. Lack of legislative framework and requirements was one of the problems we faced in the first phase of applying the new strategic approach. Over the last few years there has been observed substantial improvements of the engineering practice. A common understanding and structured co-operation between project management, experienced workers, design engineers and occupational health experts seem to be important pre-requisites for success. Legislative framework Regulation relating to systematic follow-up of the working environment in the petroleum activity (SAM-regulation) was issued by the NPD and entered into force August 1st 1995. This paper will describe and discuss key elements of the Norwegian legislative basis and discuss the Norwegian approach for implementation of occupational health requirements in the planning phase of offshore installations and modifications. One important aspect of the regulation was to apply the quality assurance and internal control principles and terminology on the occupational health area. Specifically the regulation addresses requirements on occupational health 73 in connection with planning of installations and main modifications: • • • • • • • • new Systematically transfer of experience Occupational health programme describing goals, requirements, responsibility and list of planned activities Requirement to define specific requirements Occupational health related analysis and assessments applied as decision support Active involvement of personnel with operational experience and workers representatives Illumination Indoor climate and outdoor operations Radiation The Norsok S-002 is the main design standard with regard to occupational health, but there are several other standards that give relevant support: • • • The climate in the industry was at this point of time positive; - several of the main oil companies had competent and experienced professionals with quite a good influence on decision makers. They contributed very actively to the implementation of the new regulation, but the most important thing they did was probably to develop occupational health design standards and requirements. Norsok S-005 Machinery – working environment analyses and documentation Norsok C-002 Architectural components and equipment Norsok C-001 Living quarters area The Norsok standards are available in English on http://www.nts.no/norsok The NPD was involved in the development of the standards and the SAM-regulation now refers to the relevant Norsok standards as recognised practise. This means that the Norsok standards reflect the level of occupational health conditions. If the level is reached by other means, it is accepted, but should be documented. On the other hand, if the level is not achieved, the oil company has to apply for deviation from the relevant section in the regulation. Standards – recognised practice It is not possible to discuss design standards without mentioning NORSOK – the parallel to the UK Crane initiative. The NORSOK process had several elements, some of them with a contradictory relationship. One part of it was the new cheaper/faster/simpler – philosophy that indeed had implications for design; mostly negative. Another part was the development of industry standards (NORSOKstandards), which in many cases resulted in improvements. The Norsok Standard S-002 – Working Environment was issued in 1996 and represented a specification of the functional requirements in the new regulation (above). The standard is split into two parts: Resources One important criteria for success is a proper combination of and co-operation between different kinds of personnel that have knowledge and common understanding of the relevant legal and contractual requirements • The discipline design engineers • The experienced operator/workers representative • The safety/occupational health specialist 1) Requirements related to management of occupational health in the engineering and construction phase • Procedures and work instructions for studies and analyses including scope, timing, resources etc. • List of studies and analyses to be performed • Verification activities, design reviews etc. • Working environment area charts for documentation and follow up Most commonly an HSE/occupational health co-ordinator in the oil company and a similar position with the main contractor organises the different activities and order resources. One challenge is to secure that operational staff are available on short notice to take part in design reviews etc far from where they normally work. Availability of personnel at the right time is critical for proper timing and quality of the design input. It is our experience that a clean-cut consultant based approach is not the best way to achieve good results. Consultants are often working with a too long geographically and mental distance to the project and are not in a position 2) Specific requirements on factor level • Arrangement, layout, ergonomics • Noise and vibration • Chemical hazards 74 which allows him to follow up on a continual basis and actively influence the decisions. Full or part-wise integration of occupational health specialists and operating personnel within the project team is a key aspect, but it is challenging and requires well defined rules for co-operation. • • • Cultural differences between countries and continents and between industry traditions Different approaches and methodology Lack of occupational health expertise The NPD has experienced that contractors and suppliers have been claimed for contractual violations in a way that obviously is unfair. It has been necessary to focus the role of the oil company as facilitator in order to improve the work processes and the purpose of the proactive approach necessary to achieve the best occupational health solutions. The oil company should together with the main contractor communicate the requirements and expectations and give relevant and specific advice to sub-contractors. Management tools Systematic follow up of observations and recommendations from studies, analyses, reviews etc are essential in order to prioritise, decide and implement the best solutions. In most project organisations there are established computer based follow up systems that make it simple to follow status, responsibility, deadlines etc. If this system is actively used as a management tool, it can be an effective driving force for solving outstanding issues and hit the imaginary point between too early and too late. Although significant improvements have been achieved by implementing new regulations, new standards and systematic methodology in offshore development and modification projects, this strategy is still challenged by a narrow-minded cost-benefit attitude. It is important to remind us on the probably best arguments to resist the everlasting doubt whether or not occupational health conditions contribute to increased economical values: It is a general experience that existing and common project management systems should be utilised for occupational health matters. Specialised systems will very often lose attention from the engineers and the line management. Contractual power and professional deficiency? • The Norsok standards are laid down as contractual requirements in most offshore development and modification projects. Depending on specific needs, the operator also defines addendums to the Norsok standards. In principle violations of the standard are treated as violation on the contractual requirements. This is a very strong enforcement tool, in some cases we have experienced that it is misused. • Good occupational health conditions are a pre-requisite for productivity and safe operation Due to best technical/economical practise the proper way of achieving best solutions is to implement sound requirements in the design basis QUESTIONS AND ANSWERS SESSION Question – Dr Ron Gardner, HSE That was a very interesting presentation. I don’t want to pre-empt Kevin but you’ll find a lot of parallels with our experience. I have a question for you. Have you any thoughts on how experience from one design situation can be passed onto the next, because what we come across is that teams come together, do a design job then break up so there’s no memory of what they did carried forward into other jobs. So in effect you have to repeat the whole process or they take things off the shelf. In an offshore project the contractual structure is very complex, normally with an EPCIcontract between the oil company and the main contractor as the top level. The main contractor places contracts with a lot of sub-contractors and suppliers. The “back to back” contractual principle is most often applied. This means that every small sub-contractor and supplier has the responsibility to fulfil the full scope of requirements in the original contract. Answer – Mr Sigvart Zachariassen, NPD We experience that bad solution, transferred to new projects over and over again. That’s why we have focused in our regulations, and also the Norsok standard has focused, on a systematical experience transfer. If the understanding of requirements is not the same through the contractual hierarchy, the results might well become insufficient. There are several barriers for a mutual understanding and implementation of requirements: 75 some formal analyses into the design basis. I was wondering how much success you’ve seen of that being adopted within the design process? Comment - Dr Ron Gardner, HSE Could I just say, that transfers the standards and knowledge. It doesn’t transfer experience. Answer - Mr Sigvart Zachariassen, NPD Well maybe I did not get your question right, but from our point of view it is important to collect experience data from a former project actively and document it and take it on board in new projects. Answer – Mr Sigvart Zachariassen, NPD I think it differs a lot. With regard to noise, we have a very well established methodology for estimating noise levels and also for estimating noise dose, but with regard to other factors this is not simple. We are not satisfied with the situation for chemical exposure for instance. We think that there are tools available for modelling exposure that are not as fully utilised. Question – Mr Ed Terry, Sauf Consulting Ltd You mentioned one phrase about many occupational health issues weren’t recognised as formal analyses. I think we’ve seen that maybe the Norsok standard is trying to drive 76 SYSTEMATIC FOLLOW-UP OF WORKING ENVIRONMENT ACTIVITIES DURING DESIGN OF OFFSHORE INSTALLATIONS Mrs Claudia C. González Hague and Wenche Solberg, Scandpower AS, Norway Introduction specialist is integrated in the project team during the entire project. In Norway, working environment has had special focus during design and construction of offshore installations during the last five years. Poor design solutions with respect to working environment represents a risk for occupational accidents and diseases. In the engineering phase, decisions are made that affect the occupational health standard on the installation, both during operation and construction. Implementing a high occupational health standard during the engineering phase avoids expensive modifications in the operation phase and reduces the risk for occupational accidents and diseases, which are economically beneficial for the operating company. We have also experienced that it is good practise for the occupational health specialist to give training courses to the discipline engineers in the beginning of the project to make sure that all members of the project team have necessary basic understanding of the working environment requirements in the project. Roles and Responsibilities in the Design Process The Operator has the overall responsibility for implementing authority requirements with respect to occupational health. The Operator specifies working environment requirements to the new installation in the contract with the contractor. During the engineering and construction periods, inspections and audits are performed to verify that requirements are implemented in the design. The operator shall also provide experience data from installations in operation to the project. Occupational Health Requirements Authority regulations together with the Norsok standard for working environment, S-002, apply to design of new offshore installations and modifications of existing installations. This standard is referred to as recognised practise in the NPD regulations. The engineering company shall identify all occupational health requirements to the installation and perform the required activities to make sure that the requirements are implemented in the design. During the design phase, the engineering company shall also make sure that working environment requirements are understood and implemented by their vendors. The engineering company shall also conduct audits and inspections in their own organisation and towards their vendors to verify the level of implementation of working environment requirements. The standard addresses design principles related to occupational health and working environment. The standard also covers requirements to the procedures for control and verification of design in order to ensure that the principles are implemented. The purpose of the standard is to ensure the quality of the working environment during the operational phase and that this complies with the applicable regulations. Occupational Competence in the Engineering Phases Working Environment Activities during the Engineering Phases Working environment analyses in the engineering phases may be performed by an occupational health specialist as an integrated part of the project organisation or performed on consultancy basis. When designing new offshore installations, a series of analyses and studies are to be performed and documented in order to control and verify that the design principles are met. Responsibility and schedule for analyses, control and verification activities shall be Our experience as consultants is that the best result is achieved when the occupational health 77 defined in Programme. a Working functions, needs of stairs and access platforms, lifting and transportation aids. Environment Systematic activities within working environment to be performed include: - Human-machine interface analysis for control rooms – to ensure that the working environment in the control room(s) are in accordance with requirements from the authorities, and to evaluate the control rooms’ ability to handle abnormal situations. - Analysis of handling hazardous substances/chemicals – to ensure that the risk of exposure from use, storage, handling and disposal of chemicals and other hazardous substances are eliminated or reduced to a minimum. - Outdoor operations analysis – to evaluate weather exposure at outdoor workplaces in order to identify and remedy potential problem areas related to wind chill and hypothermia. - Noise and vibration control – to identify potential sources of noise and vibration and recommend remedial measures. The work includes: « preparation of preliminary predictions of personnel noise exposure; « specification of requirements to sound insulation, sound absorption and vibration isolation; « follow-up of procurement and design of equipment packages to ensure that noise and vibration limits are adhered to as closely as possible by suppliers; « using all available data, calculate predicted area noise levels for all main areas/rooms on the platform; advise the project on noise and vibration control related matters and « witnessing equipment noise tests as part of the projects QS activities. - Material handling study - detailed evaluation of transport routes, transport methods and equipment for handling/transport of heavy items above 25 kg during operation and maintenance work onboard the installation in order to ensure safe and efficient operation as well as obtaining an acceptable working environment. - Updating of working environment area limits with predicted values and results from performed audits. Concept Phase: - Concept working environment analysis – to identify and evaluate potential problem areas as input to concept selection and verification of design. Main focus in this phase should be: location of noisy equipment, living quarter and Central Control Room; distribution within LQ; transport and transportation ways; permanent work places in respect to wind and weather. Basic Engineering Phase: - Specify working environment area limits – to establish specific limits for working environment factors such as illumination, temperature, concentration of chemical substances in the working atmosphere, ventilation, noise and vibration for each room/area on the installation as input to engineering. - Noise and Vibration control – coarse noise prediction including identify noise and vibration sources and evaluate principal acoustic, vibration and noise control solutions; prepare specific package requirements for noise emitting items for inclusion in inquiry documentation (Noise Data Sheet). − Coarse working environment evaluation – systematic evaluation of the selected concept design with respect to working environment factors in order to identify possible problem areas for further analyses or report recommendations to the design. Detailed Engineering Phase: - Detailed job safety analysis – systematic analysis of selected areas or equipment packages to ensure that risks for occupational injuries are eliminated or reduced to a minimum. - Ergonomic analysis – to identify potential problem areas in design of workplaces with respect to ergonomic factors, including evaluation of layout, clearances for performance of tasks, location of work 78 Scandpower has developed and documented methods and guidance (internal) within working environment activities in design. This documentation includes: working environment programs, checklists, specific working environment requirements (for rooms/areas on the installation(s)), working environment analyses and evaluations, working environment audits, working environment courses and electronic follow-up systems. These methods and guidance have been used in a series of projects and have proved efficient. Experience from previous projects Experience from previous projects show: - Fewer changes needed to be made during fabrication if follow up for access and ergonomics is conducted during detail engineering. - Experience and input from operators and maintenance personnel during the engineering period is important. - Difficult to follow-up space requirements of the single components/equipment packages due to total space allowed by the project. - Requirements to vendors should be followed up closely even if the vendors actually have the responsibility to comply with the EU Safety of Machinery Directive. - Material handling and transportation of all heavy equipment needs to be considered throughout the engineering phases. - Competitive requirements between technical requirements and working environment requirements, e.g. location of safety relief valves. - Useful to have an electronic follow-up system for actions. Performing Working Environment Analyses A high level of co-operation between persons from different disciplines in the engineering team, operation representatives and occupational health specialist is an important criterion for success in performing working environment evaluations. Therefore most evaluations are conducted in form of review meetings with participants from the different disciplines in the project team and from operations representatives. A working environment specialist will plan, conduct and report the meeting. HSE is a line responsibility in projects so implementation of actions from reviews is the responsibility of the engineering disciplines. Special checklists are prepared and used to be able to carryout the evaluations in a systematic way. In most projects, an electronic follow-up system is required to have an overview the status of implementation of the actions from reviews. Conclusion Working environment analyses/evaluations aid in improving working environment and help improve the quality of design. By improving working environment during the design phase, occupational health problems during installation’s operation are prevented. Follow-up activities Working environment follow up activities: - Working environment status reporting, e.g. on implementation of actions. Inspections at the construction site(s) and at vendors to ensure, that working environment requirements are implemented in design. Working also: - Verifications and audits towards the engineering team and towards vendors - - Design reviews, e.g. 3D-model reviews to verify implementation of actions from performed analyses and other working environment requirements. - 79 environment analyses/evaluations Allow experience transfer through: « participation from operation « survey (mapping) reports from existing installations « HSE data from operations Stimulates multi-discipline co-operation with occupational health/working environment in focus - Is a systematic approach to occupational health in the design process Answer - Mrs Claudia C. Gonzalez Hague, Scandpower AS, Norway Norsok came in in ‘96 and I think it’s taken a period of time to ensure that you have the right methodology, that you have the right competence in the project. I think from experience, the more active the different disciplines are, the more education and training they get in the early phase, the more effective the design reviews can be. From my experience I think they’re quite effective but you don’t get everything. There are always issues that you need to follow up in the fabrication phase and during the operational phase. Performing these working environment analyses during engineering phases is cost beneficial due to reduced need for changes during fabrication, installation and operation. It ensures improved compliance with applicable standards and regulations and also ensures that client’s requirements are also included as part of design. QUESTIONS AND ANSWERS SESSION Question - Dave Freeman, Norwich HSE Can you comment on the Norwegian state on the company losses for occupational health figures? Do you get data banks of why you have the different accidents? Can you say you prioritise them? Then can you comment on the project costs, the percentage that’s put forward for occupational health compared to the rest of the project costs please? Also can you comment finally on wind chill? Why is this so critical in the Norwegian waters? Question – Michelle Gibbs, University of Surrey In the design of an offshore installation, what consideration is given to the illumination in different areas – are the levels of lighting based on research of appropriate light levels for different work? Answer - Mrs Claudia C. Gonzalez Hague, Scandpower AS, Norway Norsok has highlighted for the various rooms and areas in the installation, there’s a different requirement with respect to lux values. For offices, let’s say, you have much higher requirements in respect to illumination than you have in access ways for example. But in terms of how they’re based on scientific research, I’m sure they’re based partly on scientific research and on experience I would assume. Answer - Mr Sigvart Zachariassen, NPD Well that was about the data collected from occupational diseases and injuries. Did I get you right? What is the basis? (Dave Freeman That’s correct). Well we have for many years collected information about both occupational diseases and injuries and we analysed the results and in both the databases we find that the design aspect is a main cause for a lot of the injuries and diseases and that is our basis. I don’t think that we have any specific figures related to cost for those. Question - Tony Garner, Conoco Do you have any input into the psychosocial well-being of the people before the engineering standards are made, such as gymnasiums or living quarters accommodation, space - bed space, personal space. Does this matter to you? Question - David Freeman, HSE: The fourth question was wind chill. Why is it so critical on the Norwegian shelf? Answer - Mrs Claudia C. Gonzalez Hague, Scandpower AS, Norway Well it’s very important because of the temperature. We are located quite far north and the wind is very strong. We have very high levels of high velocity winds in the North Sea. It is important to ensure that you protect the workers when they are performing their maintenance activities and their operations. Answer - Mrs Claudia C. Gonzalez Hague, Scandpower AS, Norway There are requirements in the living quarter Norsok standard. There are requirements related to square metres per person and also requirements for size of cabins. There’s description of activity rooms, what kinds of activity rooms are on the installations? With respect also to psychosocial, the operating company has responsibility for carrying out a psychosocial evaluation to look at manning on the installation and the type of work that they carry out. Question - Kevin O’Donnell, HSE The systems you have described - could I ask how long have they been in existence and what is the general experience with running them so far? Are they reasonably successful or is it too early to tell? 80 report and go through the systems, the methodology, the competence etc. Comment -: Dr Eirik Bjerkeboek, NPD Maybe I could comment on the psychosocial aspect. The Norsok S002 standard requires as Claudia mentioned that kind of analysis to be carried out. This is of course referring to several of the speakers yesterday. The focus on mental health should have a large focus also on the side effects. But it is extremely difficult to forecast what kind of stress level or what kind of health output you will have from the psychosocial working environment. One of the companies that has at least tried to develop a methodology here is Norsk Hydro, where they use a kind of comparing analysis with working and psychosocial environment on existing installations, and try to adapt stress levels and work load levels there into the new design. Answer - Mrs Claudia C. Gonzalez Hague, Scandpower AS, Norway I’d like to answer that. During the engineering phase, for me sitting in the project, what is required from the engineering company is to submit non-conformance requests. So throughout the design the different disciplines, when they cannot comply with the regulations, they submit a non-conformance request to the operating company for approval. It’s a system that is going throughout the entire project during the design and fabrication phase so you’re always aware of where you are actually not complying with the regulations. Question – unknown speaker Obviously the Norsok standard is in Norway. There are also other standards around in the North Sea. Can you tell us a little bit about how your efforts are to harmonise all these regulations instead of changing rules every time you cross the border. Question - Mr Curt Robinson, Acoustic Technology Ltd Does the NPD have any input during the design stage, or is it similar to the HSE where I guess the first time they get to see whether the design’s been successful is when the platform is first operating? Answer - Mr Sigvart Zachariassen, NPD I don’t think I’m the right person to explain that, but that is a matter that is discussed almost continuously and we are being told that it’s very expensive to come from UK waters into Norwegian waters. A study has been performed, I think about one year ago and it shows that the difference is not as big as it’s claimed, so I don’t think it’s a very great problem at all. Answer - Mr Sigvart Zachariassen, NPD Well it’s when the installation is operating that it is finally possible to verify. However, in our follow up activity we look very closely at how the work is being performed and if there are set requirements, for instance, for equipment depending on the layout and several things. So we pick up things in the engineering and construction phase but at the end of the day it is the level that is verified at the end when the installation comes into operation that is final. If there is some exceedance from the limit values, the operator has to apply for nonconformance and normally we do not give that in the case of a new installation. Question – unknown speaker But you have a lot of rules up in Norway with Norsok but the results in health and safety are not different. I mean the rules that you implement are not proving that it makes better health and safety. Question - Mr Curt Robinson, Acoustic Technology Ltd That strikes me as almost too late, especially I guess for some instances, mainly noise. It is very difficult to then actually apply litigation measures after the platform has been commissioned. So the designers don’t have to submit anything to you during the actual initial design stage and say this is how we’d like to set out our platform, so that they can perhaps use the experience from the NPD? Answer - Mr Sigvart Zachariassen, NPD Well the Norsok standard which we have talked about today is a design standard and it doesn’t apply for existing mobile units for instance so maybe that is sorting out some of the problems. The requirements in the Norwegian regulations are not very much stricter than the UK regulations but maybe there’s a difference in the practice of the regulations, the enforcement of the regulations. Answer - Mr Sigvart Zachariassen, NPD No they do not have to submit as a normal routine. But when we have an audit at that specific project, we normally ask for a noise Comment - Kevin O’Donnell, HSE I just want to make a comment in relation to the point the gentleman has just raised. I don’t want to pre-empt what I am going to say but 81 having heard the last two speakers, there’s a lot of common elements in what they’ve said and what we’re looking at. In seeking to follow consistency we will look very closely at what has been done in the Norwegian sector to see where we can learn and what things we can do in conjunction with the industry to try and maximise the consistency between the regimes. We’ll have to look at it very carefully. Comment – unknown speaker It’s a comment actually on the documentation of the effect of the Norwegian regulations and whether we have actually improved our health outcome from these regulations. I think you’re right in that this has not been documented on a broad basis. However, we’ve had one study on automatic pipe handling systems which demonstrates very clearly that there has been a reduced rate of injuries and accidents when this type of equipment was introduced. The results of this study are very well agreed upon by all parties. 82 DESIGN OF OFFSHORE INSTALLATIONS – DON’T FORGET OCCUPATIONAL HEALTH Mr Kevin O’Donnell, OSD, HSE Abstract health risks during design. A number of Occupational Health specialists, engineers and project staff from offshore design contractors and operators were interviewed and they explained their experiences concerning Occupational Health requirements and the offshore design process. This paper outlines the background to the consideration of Occupational Health issues in the design of Offshore Installations, and raises some of the problems and difficulties with this process. The provision of Occupational Health design guidance for Offshore Installations is outlined. HSE’s Offshore Safety Division’s Key Programme of work includes this objective and offshore design safety cases will be reviewed using these guidelines. Occupational Health risks associated with, for example, noise, manual handling, hazardous substances, food contamination, radiation, general welfare should all be addressed during the design stage, well before any metal cutting begins. Basic guidance on some Occupational Health issues is provided in the 4th Edition Guidance on design, construction and certification (HMSO, 1990) but the design guidance given for Occupational Health issues is not comprehensive, and in some cases is outdated. In some areas it has been superseded by Regulatory changes or more modern ways of thinking. The application of the Design and Construction Regulations (1996) offshore offered a new opportunity to raise Occupational Health on the agenda, but the Regulations and Guidance only address some of these issues in limited detail. Introduction Since the review of the safety regime of the UK offshore industry about ten years ago, a tremendous amount of work has been done to address the numerous hazards to safety that exist. Most safety hazards are well recognised and the industry has done a great deal in recent years to reduce the risks from these hazards. During this time Occupational Health has tended to be overlooked, particularly in the early 1990’s, largely because of the drive to address safety issues. Within Offshore Safety Division a small team has worked to raise the profile of offshore Occupational Health issues, so that they receive proper consideration both as part of routine operational work, and during the offshore installation design process. We have initiated a project to bring together good design procedures and practice for Occupational Health issues as well as addressing regulatory requirements. This paper describes the reasons for this work and introduces the next stage, the production of Occupational Health guidelines for offshore installation designers. The review concludes that the biggest single factor influencing the overall risk of occupational illness is the original design of an installation, rather than the procedures and health management systems implemented during its life. Assessment, removal and control of Occupational Health risks on the job are important, but by then installation operational staff are usually presented with a ‘fait accompli’ and must make the best they can out of the situation they face. Fundamental changes to a task may not be feasible or reasonably practicable at this stage of the operational phase. Review of Oil Industry Guidance and Approach to OH and Design Factors affecting occupational health considerations in design: There are a number of factors that can affect how well Occupational Health is considered in the design of offshore installations. These include: Recently OSD conducted a detailed review (HMSO, 1998) of how Occupational Health is considered during the design of offshore installations. The aim of the review was to identify opportunities and problems with current design methods and to recommend ways to improve consideration of occupational 83 • Occupational Health is not seen as a core design topic and there is a general lack of awareness of a problem by designers; Occupational Health requirements can be poorly specified by the operator; There can be insufficient feedback from previous installations regarding occupational health problems and their causes on existing installations; Communication and co-operation within operating companies can be poor, contributing to lack of feedback; Budgetary constraints and conflicts (eg CAPEX vs OPEX conflicts) may compromise Occupational Health consideration during design; Poor communication between the operator, design contractor and other parties involved in the design; Design reviews may not be conducted in a way which focuses on Occupational Health risks; Delaying action on Occupational Health design problems can leave them unresolved until too late in the design process; Conflict between design requirements can compromise consideration of Occupational Health; Contractors, subcontractors and suppliers may not provide adequate Occupational Health consideration; Design conservatism may hinder development of innovative solutions; Occupational Health specialists may not be consulted, or not consulted early enough in the design process; Occupational Health controls may not be installed correctly during the fabrication and construction stage. This has been illustrated by cases where Occupational Health provisions, particularly in accommodation areas, do not seem to have progressed much in some cases since early designs. One recent example of an accommodation re-design was almost a perfect carbon copy of earlier sister installations. This can lead to mistakes being repeated, and takes little or no account of previous problems and experience. There are other issues that will influence these points, one of the most important being the contractual agreement between the operator and design contractor, and the working relationship that develops during the contract. These issues are directly dependent on the financial and resource constraints imposed by the contract and project. Exploration and development offshore is hugely expensive. The costs involved in exploration, production development and associated infrastructure can be enormous. But the potential rewards are enormous and returns can be expected for a considerable period from most developments. Initial financial capital required for a development is often huge, and all attempts are usually made to minimise this. When production is underway money may be available to spend to address issues that were not properly considered at the design stage. This background encourages the tendency to delay the consideration of perceived nonessential items during initial planning and design until production has started and there may be more time and money available to • • • • • • • • • • • • Many equipment suppliers have ‘off the shelf’ design of equipment such as valves, pumps and compressors and these may cost considerably less than, for example, a ‘noise reduced’ bespoke version, and have a much quicker availability. The review indicated that this would more often be the automatic way ahead, rather than considering an alternative that might cost more in the short term, and initially take longer and more effort to procure, but would be likely to bring long term benefits in terms of reduced health risks. Fast-tracking and CRINE These concepts for projects have among their objectives those of achieving fixed, often tight timescales, and of removing any unnecessary expenditure. This may mean that tasks of perceived lesser importance may be put back, or worst still, left to look after themselves, and will tend to drive designers in the ‘off-theshelf’ direction. This can easily result in Occupational Health topics getting pushed to the back of the queue. Design contractors will be constrained by what is in their contract, and they will not get paid for what isn’t included. The financing of development projects ‘Off the shelf’ solutions When new projects or redevelopment work are being considered in some situations there is understandably is a tendency to go for ‘off the shelf’ solutions whether for complete installations (drilling rigs) or for specific equipment such as pumps or compressors. 84 through collaboration, partnerships and innovation. Promoting good physical and mental health at work is central to this programme. There is a lot being done in the industry through collaboration and partnerships, not necessarily on Occupational Health though, but the basis is there to work on. address them. Occupational Health issues often fall into this cul-de-sac, in that they are parked until it is more convenient to deal with them. This can be false economy because subsequently much time and effort can be consumed dealing retrospectively with problems at the operational stage that have not been properly addressed at the design stage. A lot of these issues clearly fall into the Regulatory framework and enforcement action by HSE inspectors can occur. Programme 3 of SHT aims to increase knowledge of Occupational Health by improving data processing methods, but this assumes the data is there in the first place. This is an area we have been working on in OSD. Another relevant factor is the way the industry has been influenced by dramatic fluctuations in the oil price, and has had to address ways of working to ensure that oil and gas can continue to be delivered to markets from marginal fields. This has not surprisingly led to cost controls and manning reductions, which must be acknowledged. But the old proverb ‘a stitch in time saves nine’ is relevant here, and spending time and effort at the design stage will pay dividends in the long term. So it should be recognised that making economies in the design phase will create problems in the future, and time and effort spent at the design stage will produce benefits in the longer term. Short term views over a 3-4 year period, reflect short-term economics and will often lead to greater costs in the long term. Purchase and supply of equipment that is potentially harmful to health is controlled by the Supply of Machinery (Safety) Regulations 1992. These Regulations require that relevant machinery meets essential health and safety requirements. For example the supplier of noisy machinery must be able to show that it is designed and constructed so that risks from noise are reduced to the lowest level taking account of technical progress and the available means of reducing noise. Health related civil compensation claims for Occupational Health issues such as Noise, HAVs, back injuries and stress are rising all the time. All of these are real issues and their causes can be found on most offshore installations. Why bother about Occupational Health at the design stage? Legal requirements In the UK there is a legal framework that requires the risks to workers’ health and safety to be reduced to as low as reasonably practicable. A company must have a written Health and Safety Policy outlining the company aims and objectives with respect to the health and safety at work of employees and the organisation and arrangements in place for implementing that policy. It is essential that Health and Safety issues be addressed at the design stage of a project if they are to be properly controlled during the life of the installation, and it is important to look at the Health and Safety Policy to see how it addresses design activities. Taking proper account of Occupational Health issues at the design stage is the most effective way of dealing with them. The problem is that time and resources are often limited. But it is much more cost effective to plan and integrate measures at this stage than later in the life of an installation. But perhaps the most important reason for properly addressing Occupational Health issues is the well being of the workforce. Who are the key people that any organisation depends on to get things done, keep production going, to deliver the goods? Investment in them, keeping them healthy (and happy) and in place, doing their job has got to be worth a lot to any company. In the short-term corner cutting may apparently pay, but in the long term it is a false economy. By reducing exposure to health risks, wear and tear on workers is reduced, their well-being is raised, and the likelihood of an employee feeling valued will rise. The Securing Health Together (SHT) initiative is very important here. The Compliance Programme (number 1) is important but in the context of issues we are discussing here the other Programmes are more directly relevant. Programme 2 of SHT aims to promote a culture of continuous improvement achieved 85 • It may be a cliché to state that the workforce is the most important asset of any company. However, an office or item of equipment can be replaced relatively quickly, but if an employee is lost either due to ill-health effects, or due to a move (particularly to a competitor), then finding a replacement and then bringing them up to speed in the job is an expensive and time consuming process. Investment in human resources will bring benefits in these areas. To address these recommendations HSE have commissioned production of design guidance for Occupational Health issues and the first stage of this work has produced guidance for noise, manual handling, and hazardous materials. This guidance will be tested on at least one development in the UK sector of the North Sea, and will be reviewed using the feedback. Next other Occupational Health issues will be dealt with, and the guidelines will then be published. Recommendations to improve Occupational Health control during design The Occupational Health design review made a series of recommendations to improve the consideration of Occupational Health during offshore installation design, and if these are put into practice they will help to address the main problem areas that have been identified, which are: • • • • SUMMARY This paper outlines the background to the consideration of Occupational Health issues in the design of Offshore Installations, and raises some of the problems and difficulties with this process. The methodology being used by Offshore Safety Division to approach these issues is outlined. The detail will be given in the following presentation. Lack of awareness by designers and project managers of Occupational Health issues and lack of effective control systems; Addressing Occupational Health too late in the design process; Lack of feedback on Occupational Health aspects of previous installations; Poor communication between operational and project teams. On a wider front HSE and HSC are leading the Securing Health Together initiatives and in Scotland this is being jointly promoted with the Scottish Executive. This is a government initiative to reduce costs to the nation of people having time off work, or being unable to work due to health problems. To ensure adequate attention to Occupational Health an offshore installation design programme should include the following key features: • • • • • • Active efforts to gather feedback from previous and similar installation design projects. Programme 1 of Securing Health Together aims to improve laws concerning occupational health compliance, including developing best practice, legislation support and law enforcement. Priorities include revising existing or introducing new health related legislation or guidance. Commitment of design contractor and operator senior management to improved Occupational Health; Awareness of Occupational Health issues within the design team, and education of engineers at the start of the project; Easy access to information on Occupational Health specifications, design guidelines and examples of successful application; Use of structured design review procedures and tools to capture potential Occupational Health related design defects; Early and active involvement of operational personnel in the design process; An expert in Occupational Health as a core member of the design team; Offshore Safety Divisions intervention strategy for the next three years includes activities to support these aims.

Relatively small sums spent during design and build (for example a slightly higher cost for lower noise plant) are known to significantly reduce or even remove the longer term costs arising from inadequate occupational health risk management. However the position often arises where there the organisation liable to the long-term costs has no link with the organisation benefiting from the short-term savings or indeed may not even be involved at the point where the decision is made to go for short-term savings even though they are likely to predispose long-term cost. The process of design, build and operate for offshore operations is extremely complex, extremely costly (with considerable financial penalties for failure to meet contractual obligations) and involves a considerable timeframe. In addition, given the enormous capital investment required in what is always, to a degree at least, a potentially risky exercise, it is not surprising that major capital investment and major builds are becoming more commonly based on consortia than individual companies acting within their own resource. Introducing a systematic structured and rational approach to improving occupational health risk management in this context is, therefore, not merely about the provision of information but also about the inclusion of the consideration of occupational health risk management as an integral part of the design to operate life cycle. The extremely complex engineering considerations involved have also created a situation where much of the design and build operations are contracted out to specialist organisations. Moreover it is not uncommon for the operation to be manned (wholly, or in part) by contract staff. Unless this is achieved, the risk remains that even ideal guidance incorporated at one point will be “lost” in the transition from phase to phase or will be “sacrificed” for (apparently legitimate) budgetary reasons at one phase without due consideration of the longer-term cost. The net result is an extremely complex project management operation involving numerous organisations many of which are involved for only a limited period and, often, only within a single phase of the Concept Design – FEED – Fabrication – Commissioning – Operation life cycle. It is essential therefore that any occupational health risk management guidance provided must come “ready packed” in a process which will allow/encourage its incorporation within the overall project management process to ensure that the provision made at one stage will be carried through to implementation at the next. Keeping track of the engineering and the cost is, in itself a major task and it is hardly surprising if “peripheral” issues such as occupational health risk management are “sidelined” either within the whole process or at one or other of the various interfaces between the stages. Even if such a process/procedure is provided, improvements in occupational health provision cannot be guaranteed unless the contract brief for each stage specifically includes the need to deliver best practice standards in occupational health. Although there can be considerable cost implications (arising from lost time, compensation etc.) from inadequate consideration of occupational health risk management even these, hard, business considerations can become “lost” in the clear demarcation maintained between CAPEX and No matter how good the information, how useful and practical the process, there is a need 89 • for overt corporate commitment to improved occupational health. An acceptance and shared ownership of the fact that detailed consideration of and expenditure on occupational health assurance in the early, design stages, is essential to deliver not only a healthy workforce but also the significant operating cost reductions that arise therefrom. • The problems in providing occupational health assurance • • This project was developed to provide both guidance on three occupational health issues (i.e. manual handling, noise and COSHH) and a framework by which the guidance could be systematically considered as an integral part of the overall project management process. • • • • • The brief given was to develop a new approach to the provision of occupational health guidance to the off-shore oil and gas industry which would take cognisance of the differing needs at the various stages in the life-cycle from Concept Design to Operation. • Manual handling Noise COSHH • The study consisted of a series of discussions with representatives of major oil and gas companies, the Regulators and a number of oil and gas industry support companies to identify: • • • • Current practice in integrating occupational health risk management into the Design-Operate life-cycle Perceived limitations on the introduction of improved occupational health risk management Perceived motivators for the improvement of occupational health provision Examples of successful risk control measures and procedures in relation to the three case-study topics • • • The results of the discussions can be summarized under three headings as follows: • The cost of inadequate occupational health assurance • • generic action-based approach based on existing good practice compatible with familiar processes and procedures capable of integrating into standard project management techniques This information was collated and used to develop a Framework for the incorporation of occupational health risk management into the design-operation life cycle. A number of conditions were established for the Framework as follows: Three topics were to act as case studies for the development of the approach: • latency period for occupational ill-health increasing frequency of consortia based projects / contracting out sidelining of occupational health clear demarcation between CAPEX and OPEX Needs in moving toward a solution Project Approach • • • increasing frequency of ill-health retirement extended periods of sickness absence It must be a process rather than a procedure. It must be a generic approach which can be tailored to any design programme (e.g. platform, rig, FPSU etc.) and any occupational health issue. It must be sufficiently structured to allow specific activities and specific decisions/actions at each of the stages in the life cycle (e.g. Concept Design – FEED – Fabrication – Commissioning – Operation). It should be linked into an accepted model of occupational health and safety management (e.g. HS(G)65). It should be built around standard health and safety practice compliant with current regulations (e.g. risk assessment techniques). It should, ideally, not use processes and procedures unfamiliar to the industry. It should be compatible with standard project management techniques.

The basic principles of risk management were applied, i.e. remove, reduce, protect with the assumption that the earlier in the DesignOperate life-cycle that risk management is applied the more likely that opportunities to remove or reduce risks will be viable. The examples below indicate the type of question asked in relation to remove, reduce, protect: Remove • Is the operation / process essential? • Will other aspects of the process train, for example, need to be adapted if selected item is removed? • Does the benefit of reduced exposure merit the potential costs? Reduce • • Can the exposure level be reduced? Are identified control measures appropriate / effective? • Are there any risk management lessons arising from past experience? • Are there any costs implications? Protect • Nuisance Noise – high noise levels impinging on, for example, accommodation areas can interrupt sleep patterns, disrupt leisure activities etc. and thereby increase fatigue and stress. The long-term implications of such problems are known to include increased accident potential and reduced general well being (potentially increasing sickness absence). • Environmental Noise – offshore operations by their nature can be subject to very high levels of wind noise which will exacerbate each of the above, although little can be done to remove such problems they need consideration in design, layout etc. to do whatever is possible to reduce the effect. This is followed by a section dealing with the costs, the problem and the approach to solution. This section is largely generic to all three sets of guidelines as the problems and, in deed, the solutions to occupational health problems are, generally, common (almost) regardless of the particular hazard. PPE, for example, should only be considered after all other alternatives have been exhausted and higher level protection is in place Following these orientation sections, the actual guidelines begin with the emphasis placed on the description of a design based risk management process which can be tailored to any particular facility. The Guidelines Each of the three sets of model guidelines produced (noise, manual handling and COSHH) begins with a listing of the relevant Regulations and an outline of the general steps necessary to achieve compliance with the Regulations. This is then followed by a section covering the general issues to be considered. For example, in relation to noise there are more considerations than the potential for hearing loss and, ideally, the influence of high noise level on communications, nuisance noise and environmental noise, should also be considered. Each of these is dealt with briefly, at a level which, hopefully, will ensure that they are considered, as shown below: • • The Guidance begins with a diagram which summaries the process as a whole. An example of this diagram, taken from the Manual Handling Guidelines is shown in Figure 2. Each major element in the design-to-operate life cycle is then presented as individual sections covering: Concept Design FEED Fabrication Commissioning Operation Communications – high noise levels can detrimentally affect both verbal and nonverbal (e.g. warning signals) communication. Such disruption can have safety implications or, potentially, increase stress levels through frustration and increased error probability. Allowance should also be made for the fact that the use of personal protection (e.g. hearing Each section is divided into three sub-sections. The first deals with the Risk Management Objectives for that stage in the design-tooperate life cycle. 92 The second deals with the Risk Management Process (the issues to be addressed to meet the above objectives) for that stage in the designto-operate life cycle. The outcomes from each stage become the inputs to the next. In this way it is possible to incorporate the noise risk management into standard project management techniques. The third deals with the required Risk Management Outcomes for that stage in the design-to-operate life cycle. 93 Concept Design Agreement of Manual Handling Policy & CAPEX / procurment constraints Examine total supplies & equipment movement requirements - create inventory Specify those items which on first principles (e.g. size, shape, weight) need mechanical handling FEED Specify non-mechanical handling operations Specify mechanical handling needs Design / procure mechanical handling and/or transport equipment / systems Monitor implementation of action from ouptut of FEED Fabrication Conduct task based risk assessments Commissioning Identify retrofit improvements to design, workplace or environment Operation Idenitfy mechanical handling Identify training needs - design courses Audit / Review Figure 2. Example of the Risk Management Process (in this case, Manual Handling) 94 The guidelines are deliberately designed to be concise, providing a top-level route map which can be used to check-off what needs to be done when, and to confirm completion. Clearly, on some designs, the work required at any one stage may be considerably greater than on other configurations however if each of the issues raised in the process is completed, and followed throughout the design process then it is likely that all the necessary steps to minimise noise risk will have been accommodated within a few weeks of the start of operations thus ensuring a high level of compliance. The main questions that should be addressed at this stage are: Additional information to expand on the points provided in the guidance and some examples of successful noise risk management control initiatives are provided in the Appendices to the Guidance. The COSHH guidelines have been used below to provide an example of an Objectives section. The COSHH objectives at Concept Design are divided into two steps: COSHH Objectives (Concept Design) STEP 1: The four primary considerations for STEP 1 are shown in the box below: • Agreement on initial COSHH policy • Creation of an initial inventory of hazardous substances across all aspects of work on the facility covering operation, maintenance and services • Collation of existing and potentially relevant COSHH assessments from all participating organisations • Agreement on purchasing policy (e.g. agreement not to enter any supply contracts without receipt of relevant Hazard or COSHH data sheets) • Is the proposed installation likely to present any potential risk to health from the use / storage / transportation and/or disposal of controlled substances? • Is any health problem in the industry traceable to the use / storage / transportation and/or disposal of controlled substances likely to be used? • Can past experiences from participating companies / organisations / industry be utilised to eliminate / substitute or control the identified risk? • Does the proposed installation present any new risks arising from the use / storage / transportation and/or disposal of controlled substances? • How can the workforce be ‘best protected’ from potential exposure (eliminate / substitute/control)? An example of the Process description, in the form of a flowchart, which links in with Step 2 above (from the COSHH guidelines dealing with Concept Design), is shown in Figure 3. The final section within each of the DesignOperate phases is that detailing the expected outcomes from that phase. It is important to note that, although presented in a general form, these outcomes are crucial in that they provide the input to the next phase. As such they become the critical information in the transition from design phase to design phase, which is, as described in the Introduction, the most likely failure point in developing a seamless programme of effective occupational health assurance which capitalises on all the opportunities available. COSHH Objectives (Concept Design) STEP 2: On this basis the importance of building the occupational health risk assessment/management assurance into the project design process becomes critical, without such inclusion (and the associated discipline of signing-off and transferring-on), the probability of control action failing to find its way through into operation increases considerably. The principle aim of STEP 2 is to start the process of converting the initial policy into practice and aims to address the question of whether to: • Eliminate • Substitute • Engineering Control 95 Outcome from STEP 1 Yes Can task / operation be eliminated? No Yes Can task / operation be substituted by lessless Less hazardous substance? No Yes If TLV's* available is likely exposure acceptable? Can hazardous be substance substituted?

Having worked through Concept Design, FEED, Fabrication, Commissioning and Operation, detailing the Objectives, Process and Outcomes of risk assessment/management for the particular topic, the guidelines then provide a series examples of how the process could operate based on a series of HAZOP/HAZID style exercises, again working through each phase in the Design – Operate life cycle. At the end of each of these sections a series of examples, taken from the industry, of good occupational health design practice are provided, not as a definitive listing of good An example of the material presented in the approach to implementation section of the Manual Handling guidelines, dealing with the Concept Design phase is presented below. HAZID 1 The first essential step is to establish links within all collaborating parties in order to freely share past experience on manual handling hazards and risk control measures used. It is also useful at this point to establish similar links with both cross-industry bodies 96 reduce-control hierarchy of best practice in risk management. (such as the Step Change Programme) and the Regulators to seek information on their experience of best practice standards. • Assess practicality of selected mechanical handling equipment in current context – initiate further examination where problems arise (where possible resolve before completion of FEED or document for future action) • Review all operations / tasks for which manual handling is unavoidable with regard to the possible provision of mechanical handling aids • Specify and review risk control measures • Optimise internal layout of storage areas / loading bays etc. to reduce manual handling requirements and/or to minimise restricted movement and constrained/awkward postures • Specify operational and maintenance activities that may present musculoskeletal risks beyond load lifting/carriage • The Policy should include, as well as standard requirements such as high level corporate commitment to reducing manual handling injury etc., the establishment of a Manual Handling process/programme and the mechanisms for signing-off actions and transferring actions from one stage to the next. This is essential to ensure that the development of a comprehensive risk management programme is maintained regardless of the principals involved at each stage. Identification of Potentially at-risk operations/tasks The past experience of collaborating parties in terms of previous manual handling risks on similar operations should be collated as a start point to identify an initial suite of potential risk management requirements. For example, information can be obtained from: • • • Actions above to be formally signed-off, documented and transferred to Fabrication Where possible similar information should be sought from cross-industry bodies and from HSE. The latter should not only include crossindustry accident data but also information from specific projects commissioned by them (for example HSE research project: ‘Ergonomic Issues in the Design and Operation of FPSOs’ includes consideration of potential manual handling problems on FPSOs). Below are the four principal issues to be addressed in HAZID 1: • • • • Previous risk assessments conducted for similar operations/tasks Past sickness absence information relating to musculoskeletal problems Past injury/accident data involving manual handling activities Agreement on manual handling policy to be used across the project up to and including operation Identification of potential manual handling at-risk tasks/operations based on previous experience Creation of an inventory of potential risk items to be moved (supplies, replacement parts heavy/awkward manual operations etc.) Agreement on the extent to which purchasing policy can be used to remove/reduce manual handling risk and top-level specification of such policies. Creation of an inventory of potentially risky items to be moved HAZID 1 should initiate the process of creating a complete schedule of items of equipment, supplies etc. (for both operational and maintenance requirements) which will need to be moved on the facility. Each of these issues is expanded briefly below: The list should, initially, make no distinction between items which could be moved manually (if necessary) and those which will clearly require mechanical handling (e.g. major items of replacement plant). The reason that all should be included at this stage is to ensure that Establishing Project Policy It is essential that a Manual Handling Risk Management Policy is established at the onset of the project to fully capitalise on the remove- 97 mechanical handling requirements are also considered systematically through the process. It is not uncommon for oversights to lead to the use of sub-optimal mechanical handling aids which can often introduce additional, unforeseen, manual handling risks. These outputs from HAZID 1 become the inputs to HAZID 2. HAZID 2 The purpose of HAZID 2 is to start establishing the detailed suite of issues to be examined fully during the remaining stages. The output from HAZID 1 should be used to further examine the following primary issues: It is highly unlikely that any list will be complete at this stage, it will be refined as the process develops, however it is essential to start as early as possible so as many potential problems can be considered during the design process. • Purchasing Policy The potential value of a purchasing policy aimed at reducing the manual handling risk of an operation is often under-estimated. A policy which requires the supplier to conform (where possible) to maximum packaged weights can significantly reduce risk. Similar benefits can be obtained from maximum packaged size and the nature of the outer packaging (in terms of allowing a good grip etc.). • • • Clearly there will be items (particularly replacement plant) where little can be done to reduce the size or weight etc. However even in some of these apparently “impossible” circumstances improvements can be made with some imaginative forethought – for example fitters occasionally need to partially strip components to get them in situ. Therefore there are potential operational benefits as well as manual handling benefits to having them delivered appropriately “semi-stripped”. • • Each of the above are expanded below: Detailed listing of potentially at-risk loads/operations/tasks Although it will not be possible to address such specific issues at this stage the establishment of a purchasing policy (where appropriate/feasible) will help to reduce the manual handling risk. HAZID 1 will have identified candidate tasks/operations from accident/sickness absence data, from previous risk assessments etc. This base needs to be developed and put into the new context. This should include the specification of areas which will involve major manual handling (including, for example, loading/unloading areas on deck and helipad, stores etc.) and the definition of start and end points of major manual handling transhipment routes. Early identification of both of these issues will enable initial specifications to be developed for use during FEED. For example: The minimum output from HAZID 1 (once all the actions have been signed-off) should be as follows: • • • • Collation of detailed listing of potentially at-risk loads/operations/tasks – identification of major manual handling sites and major manual transhipment routes. Assessment of utility and practicality of previously used control measures in the new context. Comparison of the above against Manual Handling Regulatory requirements to identify risk reduction priorities. Detailed listing of equipment, plant, supplies requiring mechanical handling facilities for design specification and purchase during FEED/Fabrication. Identify requirements for additional risk assessment in relation to “new” plant, equipment, systems where there is no past experience within participating companies. Develop outline risk control specifications for development during FEED. A draft Manual Handling Risk Management Policy for the Operation (and, thereby, for the Project) agreed, as a working draft, by all parties to the project. An initial listing of potentially at-risk operations/tasks (from past experience). An initial listing of potentially risky items to be moved. A decision on the use of purchasing policies as an aid to the removal or reduction of risk. • • 98 consideration should be given to overall storage requirements in relation to the limits on the height of racking, major manual handling routes may need additional consideration in relation to Identify risk reduction priorities • • • • Clearly, given the nature of off-shore operations involving everything from the operation and maintenance of often heavy, bulky and awkward equipment through to the “everyday” chores of housing and feeding the crew, a large number of potential manual handling risks are likely to emerge. It may make operational sense to prioritise risk mitigation action to ensure that the initial focus is on the higher risk areas and that potential risks do not get overlooked during the extremely complex process of moving through the design to operation process. floor surface, protection from the worst of the external environment, load/unload areas may need to include space for turning loads and/or consideration of the access to the route from the loading area to point of use/storage etc., consideration will also need to be given to non-normal operations such as patient evac and the need to manhandle a stretcher from almost any point on the facility to the helipad. consideration will need to be given to space requirements in manual transhipment areas where the size of the load (in particular the length) may require extra provision in relation to turning etc. where possible consideration should be given to the minimal use of stairs on major manual handling transhipment routes (negotiating stairs while carrying a load, especially if exposed to the weather can add a significant further risk) – although avoiding stairs completely will be impossible unless the issue is raised little thought will be given to alternatives. The secret in adopting a practical approach to manual handling risk assessment/prioritisation is to start with, as is emphasised in the Regulations, a systems based approach. The importance of this is that it ensures that the risk factors are dealt with at an appropriate level. For example, if it has not been possible at the early stages to reduce the weight or size of the material to be handled (e.g. by purchasing policy or by agreement with suppliers on packaged weight of material) then there is little which can be done at the task level – such risk factors may have to be taken as a given fact and other aspects of the risk equation addressed to find practical means of risk mitigation. If nothing can be done about the weight of the load early in the risk management programme, it must be considered during task based risk assessment. Some possibilities may emerge – for example, in dealing with bulk material only handling the amount that is required for the job in hand. In other circumstances there may be nothing that can be done as will be likely in relation to component weights during maintenance activities In this case it is necessary to consider other aspects of the task-load-environment-personal factors for possible avenues for mitigation. Utility and practicality of previously used control measures Previous operations will have used a wide range of manual handling risk control measures, some of which may be equally applicable in the new context. Care should be taken however to avoid the assumption that they will be as effective without considering their use in the new context. Where previous control measures do appear valid then there may be requirements which need to be fed forward into the detailed design. For example, stair climbing stack trolleys may need more lateral space than is normally allowed on walkways, stairs etc. They will certainly need more turning space than would be needed by an operator. Manipulation at the task level should however only be considered when all other avenues to deal with the issue have been shown to be impractical. Other mechanical aids, e.g. a scissor lift used for unloading from helicopters, may need considerable for and aft space for positioning etc. Other mechanical handling aids may require minimal clearances or may need temporary anchoring – all such considerations are best dealt with during design rather than as retrofits. To establish an initial risk prioritisation it will be necessary to undertake some early manual handling risk assessments covering classic risk assessment issues such as the risk factors, the frequency of exposure and the potential severity of injury. This may seem daunting at such an early stage however simple but effective approaches are possible. An initial assessment need not cover all of the task-load-environment-personal factors but 99 rather focus on a smaller suite of well established influential factors judged against a simple subjective scale as shown below: 1 low Primary Risk Factors 2 3 4 5 high Keeping the object close to the body Bending Twisting Lifting above shoulders Co-ordination Environment Carrying, moving each (e.g. on a 1 – 6 scale) and then take the product of the two. This is potentially misleading, as the subjective numbers used to describe the scale points have no mathematical meaning. The result is that if 1 = low likelihood/severity and 6 = high then 1 x 6 gives the same risk “score” as 6 x 1. On this basis then a low likelihood of a major severity has the same risk “value” as the high likelihood of a minor severity. One or more risk factors scoring 4 or 5 in the above table will merit a detailed risk assessment of that task. This will involve estimation of the frequency of the operation and the severity of the likely injuries. To calculate where the priority focus should be, it is necessary to consider both the severity of risk severity (obtained, for example, from accident/sickness absence data) and the likely frequency of occurrence (using for example with information obtained during HAZID 1). There are a number of techniques for achieving this, however when combining severity and frequency (likelihood) into a subject risk “score” many approaches assign a value to One of the best ways to avoid this is to use a matrix as shown below: Likelihood Severity 1 2 3 4 5 6 1 1 2 4 7 11 16 2 3 5 8 12 17 22 3 6 9 13 18 23 27 4 10 14 19 24 28 31 5 15 20 25 29 32 34 6 21 26 30 33 35 36 rational and practical system which can be used easily with available or, at least, accessible data. In this way each combination of likelihood and severity has a unique “score” and the potential confusion described above is avoided. To make the situation easier and provide an initial prioritisation the matrix can be blocked off in priority bands ( see below). The number of scale points or actual boundaries used to describe the priority bands is a matter of preference – there is no right or wrong, the important point is the creation of a 100 Likelihood Severity 1 2 3 4 5 6 1 1 2 4 7 11 16 2 3 5 8 12 17 22 3 6 9 13 18 23 27 4 10 14 19 24 28 31 5 15 20 25 29 32 34 6 21 26 30 33 35 36 High Priority Medium Priority Low Priority Detailed listing of equipment, plant, supplies requiring mechanical handling facilities used to develop the detailed design during FEED. Further Development. This action is self-explanatory however the importance in identifying the needs early in the process should not be under-estimated. Without such early intervention it is likely that the adequacy of provision will decrease and the cost of installation and/or the need for expensive modification will increase. It is the intention of HSE to trail the three modules during a major design process to assess the potential of the approach in practice. Should these trails suggest benefits will arise then the likelihood is that further modules, dealing with other occupational health issues will be developed along similar lines. Identify requirements for new risk assessment in relation to plant, equipment, systems Acknowledgements. The authors would like to express their thanks to the many people in the industry, from a wide range of companies, who through their willingness to discuss their actions and concerns in relation to occupational health assurance, helped considerably in framing the approach presented here If “new” plant, equipment, systems or indeed operations or layouts are envisaged where there is no operational experience held by any of the participating companies it will be necessary to charge someone (as part of the HAZID 2 actions) to undertake an initial desk-top risk assessment which can be checked, refined and developed as the design hardens during the remaining stages of the process. QUESTIONS AND ANSWERS SESSION Comment - Geoff Simpson, Amey Vectra As third author of this paper I feel obliged to say something, it’s not a question, just a comment. In Mel’s section in particular it was extremely difficult for us to get a real picture of the guidance on slides especially as someone in our parent organisation decided to use a style guide which doesn’t allow us to use portrait slides and made it a lot more difficult. Develop outline risk control specifications for development during FEED This step is essentially a collation of the outputs from HAZIDs 1 and 2 and forms the outline (or initial) risk control specification 101 There is not a specific element as such Graham. But the way regulations are now, we can say something equivalent to that. The guidance is based on the regulations as they are now. Having said that, the Securing Health Together compliance programme does say ‘examine existing legislation to see that it’s satisfactory’ and I’m sure that will be a byproduct of this process and other processes. The messages and lessons that we may be able to learn from other areas we’ll look at. We have got hard copies of the draft guidance with us, so if anybody would like to see what it really looks like, as opposed to how we had to shoehorn it on the slides, then please just give either Mel or me a shout and we’ll show you what it looks like. Question – Fiona Davies, AEA Technology Environment When you are actually at the stage of having the guidance agreed and to be made available, what form are you thinking of having it available in. Conventional reporting format or potentially the software tool? We were talking about the problem of trying to capture it on screen, but it does actually look like something I could imagine being web-based and working through the stages and that would actually enforce the carrying through from each stage to the next. Question - Chris Freeman, Phillips Petroleum You were talking about the transfer of experience and knowledge from one project to another. You mention the idea of using operational personnel who’ve worked on one project to review new designs but implied that you didn’t feel that was a particularly satisfactory method. Are you thinking of any other methods? Answer – Mr Kevin O’Donnell, HSE I think it would have to be available in all commonly used media. Personally I would like to see it available on a CD-ROM so that you are not carrying round a considerable amount of paper work at any one time. It would fit with modern working practices and be very flexible to use. It is also interesting to hear that the Norwegian standards are available on the internet as well, so I think we’ve got to consider all ways of using it. I wouldn’t say we’d set a hard and fast way, saying that people must use it this way. They can use the principles and adapt them to their own systems. I don’t want to impose changes on the existing company systems just for the sake of it. Answer - Mr Kevin O’Donnell, HSE I hope I didn’t give you the wrong impression. I think it’s a very valid method but only as part of the overall process, part of looking at health incidence data as well as using operational experience. I think it is a very valid method using operator experience, but not the only method. It should be supplemented by others. Comment - Dr Ron Gardner, HSE Can I just add a comment to that since I raised a question earlier. Trevor Kletz on the major hazards side always used to say industry doesn’t have a corporate memory and that’s a thing that always concerned me about the design side. Bringing in operational people as Kevin says is only part of it, because they only have a partial experience of their particular area. I think wherever feasible what I want to somehow see is the experience of the whole design team being captured. We need to retain corporate memory between design jobs and design teams. Question – Mr Graham Cowling, Acoustic Technology Ltd We’ve worked on designs both on the Norwegian method using the work area environments chart and on the UK systems where basically we do a lot of the engineered post build stage. One of the elements of the Norwegian system is the systematic following up of the gradual meeting of various noise limits which actually have a legal significance in the Norwegian sector. Those limits are there to be met. The requirement effectively is to apply for a deviation if you can’t meet those limits. In the UK system though, which is proposed to be based on a design process which has documentation at various stages, is there an element where the HSE are likely to say no, we don’t like what’s going on with this design? Comment – Geoff Simpson, Amey Vectra What we’ve tried to do in the guidelines that we’ve produced is that as part of the process, part of the definition of the objectives and the processes of each stage, there is capture of successful control measures that have been used before, and control measures that have been used before which haven’t proved successful. So, what we’ve created is a process that will allow that collective memory to be captured. Whether of course it is captured depends upon the people that are actually Answer – Mr Kevin O’Donnell, HSE 102 operating the system and there’s no way we can go much further than that. But the ‘aide memoire’ is now built into the process if you like. 103 104 THE DEVELOPMENT OF A HUMAN FACTORS ENGINEERING STRATEGY IN PETROCHEMICAL ENGINEERING AND PROJECTS PART 1 Mr Harrie J T Rensink, Group Advisor Human Factors Engineering, Shell International Health Services, The Hague and Martin E J van Uden, Co-ordinating Process Engineer, Shell International Chemicals, Amsterdam human factors engineering in smaller and larger petrochemical projects. Summary Introduction Although the human-machine interface in petrochemical manufacturing projects has always been considered to be an integral part of a sound engineering design, many misfits in operability and maintainability have been experienced after implementation. Although the human-machine interface in new petrochemical manufacturing projects was considered to be an integral part of sound engineering design, many misfits in operability and maintainability have been experienced after implementation. Based on that experience a vision and policy was developed by Technical and Occupational Health management at Shell Nederland Refinery Pernis and Shell Nederland Chemicals Moerdijk resulting in a human factors engineering strategy integrated in the early development phases of the business process project preparation and execution. Engineers and constructors have to deal with many (technical, legal HSE, etc.) constraints during their work, one of the constraints being the human-machine interface. Technical designers however: • are by nature more interested in the technical performance of their products, • do not have to operate or maintain the facility/installation after implementation and are therefore unconsciously less motivated to take care of the humanmachine interface, • have insufficient knowledge of people’s physical and mental behaviour. The benefits of this strategy are identified both in business terms (economics) and in working conditions; e.g. improvement of Health, Safety and Environmental (HSE) aspects. Based on historical data it is now identified that for a typical $ 400 million petrochemical project the strategy can result in a reduction of : • • • 0.25 - 5 % of capital expenditure (CAPEX), 1 - 10 % of engineering hours and 3 - 6 % of life-cycle costs of facilities (OPEX). For these reasons, application of human factors and ergonomic principles is 'easily forgotten' when decisions are made during design. In 1992 the Technical management and Occupational Health management at Shell Nederland Refinery and Chemical complex at Pernis and Moerdijk set up an Ergonomics Steering Committee (STER) based on a defined policy. Further a multi-disciplinary working group, reporting to STER, was installed to improve the implementation of ergonomics in projects as well as to train and give information about ergonomics to project staff and engineering contractors. At Pernis and This paper consists of two parts. Part 1 describes the main drivers of the development of a human factors strategy within Shell Pernis and Moerdijk organisations. Part 2 will give a detailed view on the actual management of human factors in petrochemical projects and will evaluate the costs and benefits based on the experience of implementation 105 Moerdijk, the goal is to integrate human capabilities in the design of work systems, like production facilities, workshops, laboratories and offices. Systematically integrated in all project and design phases, human factors engineering principles results in an effective, safe and healthy functioning of people. The benefits are identified both in business terms (economics) and in working conditions (HSE aspects), resulting in a reduction of life cycle costs of facilities. the current definition at Shell Pernis based on the ISO-6385 standard: ‘Ergonomic principles in the design of worksystems’ [ISO, 1983]. This ISO-standard describes the starting points and applications of human factors engineering principles in the design of worksystems. Before defining the scope of human factors engineering it is necessary to discuss terminology. Human factors engineering and ergonomics were originally two fields of study, which have evolved into one. Why Human Factors Engineering Human factors engineers and ergonomists use the same techniques but the origin of the two fields differ: • Human factors traditionally emerged from a military background and concentrates on human performance- i.e. the effect humans have on their working environment. • Ergonomics focuses on the safety and comfort of workers- i.e. the effect the working environment has on humans. In practice these two disciplines are inseparable and they have therefore evolved into one single discipline. For this reason the terms ‘human factors’ and ‘ergonomics’ tend to be used synonymously in this paper. At Pernis and Moerdijk sites the ergonomics working group (WEER) listed a number of maintenance misfits, the so-called Ergonomics "Top Ten". Inefficiencies in the field of material handling, vertical pump lay-out, hoisting equipment and valve operations were identified. Results of task analysis studies revealed problems in control room buildings with regard to the lay-out of the panel room, noise, lighting and console lay-out. In the field of 'human/computer interaction', inconsistencies were found in the coding of information, as well as a lack of standardisation in the design of the graphical displays. In other businesses, for instance Information Technology, Human factors engineering is also called ‘Usability engineering’ or ‘User centred design’. Also pre-start-up and post implementation reviews indicated efficiency problems as the result of sub optimal human machine interface design. E.g. in the Pernis HYCON plant (Shell 1986) many pre-start-up audit recommendations focused on improvement of operability, accessibility and maintainability. It was concluded that during engineering phases opportunities could have been taken to optimise the design without increased capital expenditure in many cases. Even in recent post implementation reviews of some international projects the same conclusions were drawn. After start-up of a brand new refinery in the Far East in 1996 the following statement is illustrative: “Basic concept is not an operationally friendly machine”. Human factors engineering is above all aimed at optimising the part of a work system called Human machine Interface (HMI). In particular, it is concerned with cognitive (information and knowledge transfer) and physical interactions that occur at the interface of the human with technical systems. Also environmental factors such as noise, light, climate, vibrations and organisational aspects may play an important role designing an optimal human machine interface. In the design of work systems and work places, know-how of various sources is being used, such as psychology, physiology, anatomy, labour-organisations, information-transfer and knowledge about environmental factors (see figure 1). To effectively apply ergonomics, know-how is also necessary of design techniques, project management and businesseconomics (investment decisions). Definition of Human Factors Engineering Human factors engineering is an applied science aiming at the integration of knowledge of human capabilities and restraints with product design, workplaces and installations in order to improve the efficient, comfortable, safe and healthy functioning of people. This is 106 Figure 1: Knowledge areas of Human factors engineering • Causes of Resistance Against Human Factors Engineering Lack of competence of design technicians Probably one of the most important reasons for this is that designers of machines and tools often have received only technical education. By nature, technicians are more interested in the technology involved in their design than the user-friendliness. As the designer usually will not work with or maintain the machines and tools designed, he will not be confronted with the shortcomings. Therefore, a designer often hardly realises the consequences of certain design decisions have for the users. This is amplified by having insufficient knowledge of people’s physical and mental behaviour. There is a wealth of literature describing ergonomic research dedicated to the correction of existing problems. These problems arose as a result of lack of attention for the user in the design. Few literature references can be found describing human factors engineering as an integral part of the total engineering process. By paying attention to the capabilities and constraints of the user during the conceptual design phase, problems during life cycle of a facility have been be prevented. As will be shown later, the efforts and costs by following this philosophy are much smaller than in the corrective mode. • Lack of focus of the Human factors engineering discipline Not only technicians, but also human factors engineers and ergonomists are to blame with respect to the low human factors input in design and engineering. Too much effort is put in research identifying and solving existing problems. Ergonomists should strive to convince ‘champions’ in the organisation of the We may ask ourselves why preventive human factors engineering is not always selected over curative human factors engineering. A number of arguments for this will be given in the following sections. 107 factors implementation being costly and having a negative effect on project schedule. added value of an ergonomically designed work systems or products. This may be done by transferring knowledge about human factors principles and ‘best practices’ to project managers, construction managers and line managers of organisations. • An overestimate of the designers own competence Research shows [Slappendel, 1994] that a majority of the designers think that the intuitive application of ergonomics is possible (the common sense approach). Results of pre-startup reviews of petrochemical facilities demonstrate that this is a misconception. Often, a multi-disciplinary task force performs such a review prior to the start up of a petrochemical facility as a final check on safety, operability and maintainability. In particular the lack of structural application of ergonomics in the design may be regarded as the cause of poor operability of some new facilities [Shell, 1986]. • Lack of ‘fit for purpose’ standards and guidelines Technicians hardly have knowledge of the physical and mental behaviour of people, necessary for designing a proper human machine interface. The existing ISO-standards [ISO, 1983] and technical approaches - aimed at assisting the technicians - are poor. The reason is that the level of these ISO-standards is rather abstract. Therefore the guidelines do not have sufficient added value to be incorporated in a list of technical design specifications. This situation does not promote the integration of human factors in design. Ergonomists working in the field should undertake action to ‘translate’ the ergonomic standards so that they can be used by technicians. This “translation” should be focused at frequently occurring operational and maintenance problems. To this extent, an analysis of frequently occurring problems may be useful, however existing rules and regulations of governing bodies may help to set priorities, too. Success Factors for the Development of a Human Factors Engineering Strategy After many years of experience with implementing human factors in design and engineering of petro chemical facilities it has been identified that a number of key factors enabling the successful and effective implementation of human factors in an engineering project need to be fulfilled. • Image problem Another reason for human factors engineering not being fully exploited in new designs of production facilities is due to the fact that line management, and people in general, do not well understand the art of ergonomic engineering and still relating it to the design of tables and chairs. People underestimate the power of application of human factors principles in the design of production-facilities. There is a clear image-problem! • Realising management commitment One of the most important conditions is the (active) support and involvement of line and project management. Without this support most initiatives are doomed to fail. Involvement should not only come from top management, but also from middle management and project leaders. Management support can be obtained or increased by reports about demonstration projects. These demonstration projects should clearly show the benefits of the human factors design strategy. The key-figures in an organisation (managers of design-, production and maintenance departments, occupational health service) should be fully informed about the of ergonomic integrated design and engineering. It is important that they know were to obtain knowledge about human factors in order to be able to identify problems and to deal with them in an adequate manner. • Awareness problem Another serious problem related to a successful implementation is that line management often considers of human factors as a kind of luxury with little added value. It is sometimes addressed in terms like “the ribbon on a gift parcel’ or ‘we do this only to satisfy the plant personnel’s wishes’. In projects which do not have ergonomic principles integrated during the front end loading we often see that end users criteria are being developed during detailed engineering, thereby frustrating project managers and as a result unwanted scope changes and extra investments. These experiences do enforce the idea of human • Providing a clear vision statement; priority to new plants An organisation should give priority to the integrated implementation of human factors in new construction projects over the solution of existing problems [Rensink, van Eijsden, 108 ergonomics platform was founded in which workfloor employees from operations, maintenance and various engineering disciplines work together in order to define norms, standards and tools to help designers to apply plant user’s experience. 1991). This is supported by economic analyses. A number of so-called post-implementation investigations showed that in the first few years after starting up a factory often problems occur with the lay-out and operation of equipment having a negative effect on the efficiency of the company as well as on the health and safety of the employees. These problems are subsequently cured at high cost or remain to exist throughout the entire life cycle of the plant, with all negative consequences. Experience so far shows that the participative ergonomics approach has led to the necessary support within the Shell Pernis and Moerdijk organisation. The understanding by both middle-management as well as the end users of the importance of ergonomics in business has increased significantly. The plea to give priority to new constructions is also based on the vision that specifications for new plants will result in simple and applicable guidelines and tools for assessment of existing plants. • Management of ergonomics in the design process To manage the integration of human factors in the design process efficiently, a number of specific conditions have to be met: • Making available practical tools and techniques Human factors engineering offers a number of design methods taking user demands into account in a structural way. An example of this is shown in literature as the Doering approach. However, this method is rather complex and theoretical and not designed to function in petrochemical design and engineering. Therefore, at Shell Pernis and Moerdijk, a number of ‘fit for purpose’ engineering and management tools were developed that are specifically aimed at the design of petrochemical plants. • • Ensuring structural input of end users in projects Recent publications report positively about projects applying the principle of so-called ‘ “participative ergonomics”. This approach values the structural participation of (end)users during all phases of improvement or construction projects. This multi-disciplinary approach uses knowledge from all organisational layers to realise an innovation. • In the international literature the participative approach is sometimes called ‘sharing ergonomics’. Some ergonomic scientists reject this approach as it is considered to be ‘giving away the art of ergonomics’. This defensive attitude is counteracted by the statement: ‘ergonomics is nothing unless it is applied’ [Wilson, 1994]. This contradicting vision of Wilson supports participative ergonomics as an effective strategy for implementation. • In the conceptual phase of a design it is necessary to conduct an analysis of all tasks that have to be performed (operation, maintenance, inspection, transport, cleaning etc.) in the future plant. HMI's identified as ‘critical’ should be analysed and translated in ‘user demands’. These specifications should be part of the ‘basis of design’ document of a project. The user demands should meet equal treatment and impact as technical and other specifications during the design and project phases. This is a difficult task since designers and builders already meet a wide variety of conditions, such as economical, technical, legal, safety, health and environmental demands. Adding end user demands will however balance these conditions and lead to a more effective design. The technical disciplines, vendors and subcontractors should all work together and concurrently to guarantee the incorporation of human factors in the design. Experiences of the group of end-users should be taken into account. A design and project approach in which the above conditions are taken into account and anchored in the procedures of the Quality Management System will result in a design guaranteeing an efficient task-performance. This will be visible in improvements in all related areas. Shell Pernis and Moerdijk vision also means that participative ergonomics is applied. To explicitly use the practical experience of the workforce during design and engineering an 109 Management of Human Factors Engineering in Projects Interfaces forms part of the Basis of Design (BOD). It was learned that it is important to address human factors engineering right from the conceptual phase of the project. In Pernis this experience resulted in the development of a standard procedure, the Front End Ergonomic Evaluation Matrix (FEEEM ) design analysis. This design analysis identifies operational and maintenance tasks at an early stage of a project, that is during the feasibility and/or definition phase, and is the 'motor' for a sound ergonomic design. The FEEEM is executed by a multi-disciplinary team and the results, i.e. potential bottlenecks and recommendations on human-machine At this moment, based on further experience with several smaller and larger projects, the development of, the so-called Ergonomics Management and Information System SNR/C (EMIS), is ongoing. The procedures, design tools, standards and guidelines within the system are considered to be necessary for assuring a proper human factors design. The EMIS scheme is shown schematically in table 1. Table 1: Ergonomic Management & Information System (EMIS ) Guideline on the implementation of ergonomics in engineering and projects Information and training tools Project management & Quality tools Engineering tools Necessity of the Quantification of the Benefits of Human Factors Engineering: The Development of a Cost Benefit Model Procurement management tools Construction management tools economical facts, we will now focus on this question. At Shell Netherlands Refinery and Chemical complex in Pernis and Moerdijk the benefits of efficient design as a result of the application of human factors have been demonstrated in a number of projects [Rensink 1992, Rensink 1994, WEER 1995]. Based on many case studies it was obvious that application of ergonomics may realise considerable savings on the cost of production and maintenance in combination with increased safety and reduction of physical strain to workers. The advantages for the employees are fewer health complaints and workplaces which are more safe and comfortable. For the company the benefits will be expressed in terms of increased efficiency and reliability leading to reduction in life-cycle costs. [Rensink, 1996]. Moerdijk, in co-operation with the NAM has recently developed a cost-benefit model (Rensink, van Uden, Aartsma, van Eijsden, Dekker 1996). One of the initial starting points of developing a cost benefit model was for awareness purposes. However it is now experienced that the model is of value not only In many cases, ergonomics is incorrectly regarded as an additional cost to the design. The benefits offered by ergonomics are not always clear to all. A complication in this respect is that not all benefits can be directly expressed as tangible financial savings. Many benefits are intangible and not easy to use to justify an ergonomic approach. In the above we have seen that it is imperative to convince ‘champions’ within the organisation of the benefits of ergonomically design. The better the arguments, the more effective one can carry this message. Since many decisions in business are based on These case studies have led to the opinion that the application of ergonomics may reduce lifecycle costs of petrochemical installations as shown in figure 2. To support this opinion Shell Netherlands Refinery and Chemical complex Pernis and 110 during project preparation, but also during the execution of projects. The goal of the method is to visualise the potential benefits of ergonomically design and to serve as an aid to process technicians, human factors engineers and project managers who have to take decisions about the design in new construction or improvement projects. Figure 2 Cash flow during the life cycle of a petrochemical installation comparing an ergonomically and a non-ergonomically design. Note : for trend indications only [Shell, 1995]. Similar to the description of the case studies a distinction is made in the cost-benefit model between tangible and intangible economical benefits of ergonomics. A number of main areas are acknowledged in the model with potential exploitation benefits by application of ergonomics. These main areas have been listed together with examples of these benefits as shown in table 2. With regard to the economically intangible benefits - to be found mostly in the main areas of health, safety and environment - the risk must be determined with respect to the frequency, the number of people involved and the consequences for individuals, environment or hardware. In the case of non-feasibility of the investment, the risk should be avoided some other way. This may be done by nontechnical means such as instructions, requirements or procedures. In most case studies, the economically tangible exploitation benefits can be calculated easily from reduction in time or material that was spent and loss reduction. These benefits should fit the return-on-investment policy of the company. If not, the criteria may be relaxed depending on the impact of the economically intangible risk or danger. In part 2 of this paper the use of the cost benefit model and the evaluation of human factors implementation in projects will be discussed in more detail. 111 Table 2. Benefits resulting from the application of human factors engineering by main area Main area Example of possible savings 1. Operations less waste decrease in number of failures increased productivity 2. Maintenance less labour less waiting less material necessary less administration improved quality of maintenance 3. Reliability less mistakes less machine failures 4. Health Reduced risk of accidents Increased motivation less sick leave less physical load 5. Safety better visibility Improved safety Reduced risk of accidents Reduced risk of stumbling 6. Environment less waste 7. Legislation Comply to the legal rules Comply to the legal rules 8. Labour Reduction of labour expenses Improved functioning of personnel Reduced sick leave fees Conclusions and Recommendations It is essential to define and analyse the critical human machine interface in the conceptual phase of the design. To assure these procedures properly, a quality system is needed. The profit of a production system is largely determined by the people working in it. To optimise the performance of these people, human capabilities and technical equipment should be fully compatible. It is therefore imperative that in addition to financial and technical aspects, human factors are also taken into account in the design of a production system. The challenge for human factor engineers and ergonomists within large organisations would be to motivate ‘key people’ in project management to implement human factors in the business process preparation and execution of projects. A human factors policy and quality assurance program is needed to support this. This means that fit for purpose engineering tools and techniques have to be developed and training of the various target groups plays an essential role. Self management of human factors issues should be one of the drivers. Many work situations currently considered to be problematic were caused by insufficient attention for the design of Human machine interfaces. Such problems can be prevented by structurally applying ergonomics in the design. 112 EMIS.MG1, Technical Projects Department (TAP) Shell Nederland Refinery, Pernis, 1996. Vendors and equipment suppliers should be informed about the significance of taking userdemand structurally into consideration during the development of a product. A simple (3 D CAD) prototype or mock-up to be used in the test phase by future users may offer an inexpensive and effective method to alleviate the reduction of user-unfriendly designs. In prioritising solutions to potential problems it is recommended to focus on deleting future tasks thereby reducing capital expenditure as well as life cycle costs. Whenever a decision on investment in ergonomics is to be taken, these aspects should be considered explicitly.

However, especially for projects in the petrochemical industry, a clear recipe cannot been found in literature. Much wise words have been written but an incorporated control system is not found. Although the man-machine interface in petrochemical manufacturing projects has always been considered to be an integral part of a sound engineering design, many ergonomic misfits in operability and maintainability has been experienced after implementation. Based on that experience a vision and policy was formulated, which resulted in a human factors engineering strategy integrated in the front end loading (the early development phases) of the business process of “project preparation and execution”. In chapter 2 the project business process is analysed. It will be discussed where and how ergonomic principles should be integrated in the process. Chapter 3 will further give the total framework in terms of a warranted quality system, including management monitoring tools and system auditing. The benefits of this strategy are identified both in business terms (economics) and in working conditions; like improvement in Health, Safety and Environmental (HSE) aspects. Based on historical data it is now identified that for a typical $ 400 million petrochemical project the strategy can result in a reduction of : • 0.25 - 5 % of capital expenditure (CAPEX), • 1 – 10 % of the total engineering hours and • 3 - 6 % of operational and maintenance life-cycle costs of facilities (OPEX). In chapter 4 the main driver for integrating human factors in the technical design process is discussed, being the benefits of integrating ergonomic principles in the business process. One could discuss to deal with costs and benefits in the first place as well, but in this article we have chosen not too, as the cost/benefits are probably better understood after reading about the management system and underlying tools. In chapter 5 an example of integration of Human Factors Engineering into new engineering developments will be given. This paper consists of two parts. Part 1 describes the development of the strategy starting with creating awareness within an organisation up to the general approach based on a developed vision and policy. Introduction The traditional ‘design process‘ After the birth of an idea to invest in a petrochemical plant, either for economic or other reasons, a conceptual design is made, on basis of existing, improved or new technology (ies). The conceptual design is normally followed by a study into the feasibility of the project and an early (economic) evaluation will indicate whether to proceed with the basic Part 2 will give the reader insight in the actual Project Management and Quality Assurance of Human Factors Engineering in petrochemical projects. 115 engineering study during which the project is further defined in terms of scope, implementation and financing.

In most petrochemical companies this evaluation is the basis for approval of the project. During this front end engineering phase typically some 5% of the capital is spent. After approval of the project the implementation phase is started including the detail engineering, during which the equipment and material specifications are completely described in requisitions, being the starting point for the procurement. It should be noticed that many petrochemical companies have slimmed down their engineering strength, relying more and more on the aid of engineering contractors. Although this is attractive from a staffing point of view some "punishment" for this policy is received as well. During detailed engineering drawings (or nowa-days drawings based on data) are produced to enable the constructors to build the petrochemical facility. During the last decades (two dimensional) computer techniques have been increasingly used and during the last decade graphic oriented 3D computer imaging has been used, while today 2D and 3D design is integrated on basis of object oriented design and engineering. Today virtual reality is commonly used on the construction side as well after construction the new facility is tested and started-up. Engineering contractors "unfortunately" do not operate the plant and are therefore not obtaining enough feedback (as a company engineer will) to improve the level of his engineering skills with respect to anticipating life-cycle operations, maintenance and other risks. Therefore and further greatly depending on the type of the contract, EC's are not always too interested in the plant life after construction has finished. The process as described above can be shown in relation with time schematically, showing the deliverables of each process step on the right hand, as shown in figure 1. The above constraints definitely influence the quality of the projects. The input of engineering disciplines in the design process Those who have read the previous paragraphs seriously may have noticed that some important participants in the project have not been mentioned yet. This important group of, let us say "potential" contributors to the design, are often NOT, TOO LATE or in only a COMMENTING WAY involved during the design process. They are those who have to operate and maintain the plant for many years to come. Lack of user participation in design During the process of design, engineering, procurement and construction many engineering disciplines are involved, e.g. process technologists/engineers, mechanical, electrical, civil and instrumentation engineers. Cultural, strategic, and logistic considerations give a continuous input during the design process, resulting in decision mostly influenced by conflicting arguments or constraints. Often the capital investment must be incorporated into existing infrastructure and especially in recent years much capital investment is spent in retrofitting and de-bottlenecking existing units. Of course these ‘end users’ were always recognised as participants in a project, but more in the sense of giving comments to a design or a document. Seldom have they been recognised as really contributing to the design as a demand defining participant. Good engineering is considered when all disciplines mentioned are working integrally and where mutual empathetic behaviour is shown. Although it is sometimes said that this is the project managers role, we have noticed and are of the opinion that the system (organisation and availability of the correct procedures and behaving culture) in which the responsible project manager has to work is of determining influence to the success. From interviews with designers, engineers, constructors and project managers as well as operators and maintenance workers it can be concluded that there is a difference in attitude between the two groups, in that the first group is motivated to deliver a product that full fills the "basis of design" and concentrate themselves on those issues but that the endusers are motivated to operate and maintain the plant in an efficient and effective way and are 117 even after already making use of graphic but static oriented 3D computer programs. This is due to the fact that project and design organisations and their engineering contractors have not the appropriate business controls in place to make sure the defect is addressed properly. Furthermore those who might contribute to avoid ergonomic misfits, the endusers of a work system, are not often consulted. more concentrated towards the life-cycle. Although engineers told and apparently thought that they had sufficient empathy for the life-cycle, more detailed questioning brought them into the situation in which they concluded and confessed they were not enough taking the life-cycle of the plant under design into consideration. The attitude of the engineer can be generally explained as an attitude in the sense of : “......as long as it’s working I did a fine job.....” Operators and maintenance workers on the other hand complain that they need more effort to do their job during the exploitation as a result of user unfriendly designs. They also claimed that this increases exploitation costs. This can only be best achieved by an ergonomic awareness program for all those involved in projects, through organisation and management procedures and last but not least by showing the economical and noneconomical benefits of human factors engineering in projects. Furthermore the application of new simulation tools based on data centric and object oriented, and thus 2D/3D integrated (dynamic) engineering systems, with a proven history in the automobile, aircraft and shipbuilding sectors of the industry, will lead to extremely simple and early 3D simulation of the plant under design. This leads to better understanding an early “design out” of ergonomic misfits as well as optimised life cycle oriented designs. The fact is that if end-users, as being the representatives of the operator/owner, are insufficiently involved during the design and construction phases, this results in a negative influencing factor what is generally identified as limited ‘client commitment level’ (CCL). However a new dilemma exists in view of availability of operational and maintenance staff during the design and methods should therefore be developed to overcome this dilemma efficient. Management of Human Factors Engineering in Projects; The Procedure to Follow Problem definition Introduction Ergonomics or human factors engineering is "easily forgotten" during all phases of a project (Refer to Part 1 of this article for the arguments leading to this statement). This leads to many disadvantages, amongst others extra costs during the further life cycle of the plant for operations and maintenance, and additional health and safety risks. Conclusion of the above analysis In this procedure, the human factors engineering activities, as experienced in a number of recent projects, are described in relation to the project phases. On the left-hand side the status of the project is given, ranging from the feasibility phase, through the definition (basic engineering) phase into the detailed design, procurement and construction phase. It can be noticed that already early in the design ergonomic demands have to be specified; the main reasons being : • that it is in this phase that inside battery limit (IBL) operational and maintenance philosophies are being defined • that the design is still flexible in its scope definition, so that ergonomic demands, especially on IBL philosophy level can be easily and at no cost be integrated in the design • demands and scope ergonomic categorisation can be set for use in the basic and detailed engineering phases Too many ergonomic misfits exist in petrochemical plants, even those recently built The business process flow diagram as given in the centre part of figure 2 can be followed to Furthermore those who might contribute to avoid ergonomic misfits are not often consulted. Not enough emphasis is paid to the many tasks which have to be done when the plant is in operation and has to be maintained. It can be concluded that the design process should have incorporated more means to assure the knowledge of ergonomics, human factors engineering, task analysis of which the results have influence on the design and user participation. 118 understand the scope, purpose, organisation and management of human factors engineering in projects. Keywords in this procedure are : Plant lay-out, Human Machine Interface design, Control room and Human Computer Interface design, Ergonomics, User participation, Client commitment level, Operability, Maintainability and System Reliability. The purpose of this procedure is to integrate the user’s requirements into the design of a system at the right time, well in balance with the technical and economical constraints, with respect to project investment as well as life cycle cost savings and occupational health and safety benefits. In doing so, the design will also reflect the way the future operators and maintenance people of the system want to utilise their system effectively while at the same time they understand and accept that impossible demands in view of additional investment versus low benefits, are not implemented. The procedure in general leads to lower Capital expenditure (CAPEX) as well as lower life cycle costs of installations and costs of plant change (Shell, a). Below the activities found back in the procedure are discussed; a good quality control is guaranteed when there is proof in the form of deliverables, sometimes integrated in general reports, like BDEP packages or Project Specifications. The type of deliverables is indicated on the right hand side of figure 2. Identify necessary human factors engineering input with respect to the project scope The person responsible for putting together the Basic Process Design Package (BDP or often called BOD) and/or the Basic Design and Engineering Package (BDEP), often the process engineer or the project coordinator/manager, should discuss and evaluate with the human factors engineer, the necessary effort for the project. Within our Company protocols and checklists for facilitating this discussion are available. Inform project meeting team/manager/Kick off The process engineer informs the project team leader or manager about the proposed strategy, including the initial costs (it is assumed that the project team leader or manager is an experienced professional and relates the initial costs to the benefits to be captured later, although many times the challenge from the project team leader indicated differently. The agreed Human Factors Engineering plan of action is then part of the agenda of the project kick-off meeting. Within larger projects (> $ 50 million) the human factors engineer often plays a co-ordinating role. Executing a Human Factors task analysis in basic design and/or definition phase is crucial for catching the technical/usability requirements of the human machine interfaces early. After these requirements are identified and recorded, there is a standard approach to follow during the proceeding phases. This procedure is applicable for new grass roots projects as well as for brown fielders and de-bottlenecking or major retrofitting. The procedure demands the co-operation between operations/maintenance, process engineering, project management, construction management and the engineering contractor. Discipline engineers normally do not participate during the analysis or audits, but are consulted along the road. Nominate the Project Ergonomics Team (PET) The person responsible for drafting the BDP and/or BDEP should nominate (in consultancy with the appropriate discipline managers) the participants of the PET. The Project Ergonomic Team normally consists of a (lead) process engineer, participants experienced in operations and maintenance, sometimes specialists (mechanical, instrumentation) depending on the type of project and the human factors engineer. The policy with respect to human factors engineering is geared towards achieving an optimal Human Machine Interface for installations, control rooms, work places, laboratories, and offices. It is essential that the persons who are ultimately responsible for ensuring a user friendly design are the designers, engineers and project managers executing the project; they need the input of life-cycle users in time to avoid later changes during detailed engineering or even worse during construction, not to speak about changes during the life cycle as such. Decide the necessary training for the project It is necessary to decide what kind of training is appropriate for the project, based on the project scope and the competence of project participants. For example, before the execution 119 delivery items and (critical) Skid packaged units should be part of the report (Shell, f). In case of control room or re-instrumentation projects the management of information needed for graphical display design is of utmost importance to achieve an effective human computer interface along with the more traditional design tools like e.g. link analysis methods aiming at an efficient control room building lay-out for human efficiency improvement during normal and emergency operations. of the FEEEM ® design analysis, it is necessary that the nominated participants of the PET meet several criteria: Operations/maintenance personnel should have followed a training module focussing on their function within the PET team (Shell, b; Shell, c) Process engineer/discipline engineer and project manager should have participated in a full scope human factors competence improvement training, focussing on costs/benefits and implementation procedures with respect to management of Human Factors engineering during all phases of a project. It should be considered to have engineering contractor and/or vendor representatives participating during ergonomics workshops, if thought relevant. The human factors engineer will co-ordinate the execution of the training requirements as specified in this step of the procedure. Normal training is ranging from 4 to 8 hours. Include the FEEEM report in the BDP or BDEP/PS document The person responsible for co-ordinating the BDP or BDEP/PS document incorporates the FEEEM® report into the BDEP document. At the end of the BDEP phase the FEEEM report will be up-dated and the resultant actions derived by the FEEEM® report should be verified in relation to the scope of the BDEP/PS and integrated into the initial plot plan. Assure FEEEM® analysis results, for instance identified ‘soft boxes’ of critical maintenance or logistic routing are integrated in the layout of plant. Execute FEEEM ® design analysis This analysis should be implemented by the PET according to the procedure. The Frond End Ergonomic Evaluation Matrix design analysis describes a multi-disciplinary task analysis method to be apply during feasibility or definition phase to evaluate potential ergonomic bottlenecks in the design. This procedure is part of the Pernis Projects Quality system (Shell, d). A standard part of the FEEEM® design analysis is implementation of the Identification of Valves Analysis (IVA®) (Shell, e). The results of the FEEEM® design analysis along with the IVA® are documented in the FEEEM report. Also the strategy with respect to implementing ergonomics in long Determine Ergonomics Implementation Plan End of BDEP/PS phase the Ergonomics Implementation Plan is set up to secure the ergonomic requirements and demands, resulting from the FEEEM analysis, during detail engineering, procurement and the construction phase. For projects less than $ 5 million CAPEX, it is in general sufficient to include the FEEEM® report into the Project Execution Plan/Project Implementation Plan. The project manager should be committed to and is responsible for the execution of the Ergonomic Implementation Plan. 120 Project preparation START Determine HF input Inform project team 1 2 Nominate PET 3 Determine training program Execute training PET Feasibility phase depending on decision Basic engineering phase EPC phase post implementation phase 4 5 execute FEEEM 6 Include FEEEM report in BDEP 7 Update FEEEM report 8 Ergonomics implementation plan 9 Quality doc.

Ergonomics Implementation Plan Requisitions: Vendors and Construction Contractors Q doc. Ergonomics Construction Plan PIR report RR1464-a.af3 Cost and Benefits Execute model reviews/audits To ensure that the ergonomic requirements are met within the project, a 3D CAD model review is used during 30%, 60% and 90% of the detailed engineering phase (see chapter 5 for special integration of ergonomic analysis with state of the art 2D/3D integrated CAE systems). Critical operations and/or maintenance activities should be simulated (preferably dynamically) during detailed engineering making use of new technologies in order to check the operational and maintenance procedures as indicated in the FEEEM® report. Often the life-time proves that impressive constructed procedures do not work in the life-cycle and have to be violated through safety and health risks and costs; dynamic functional simulation, now-a-days becoming available, will be more and more used. Special attention should be given to Skid packaged units. Showing costs and benefits of programs normally motivate professionals to apply or not apply programs. To demonstrate the benefits of the implementation with respect to costs an extensive study was done into the cost and benefits items by Shell Nederland Raffinaderij and Shell Nederland Chemie in Pernis and Moerdijk, in cooperation with Nederlandse Aardolie Maatschappy Assen some three to four years ago (Shell, g). Generally it was found that benefit/cost ratio for new (grass roots or brown field projects) are high, but that also in de-bottlenecking or retrofitting projects the balance between costs of analysis and their benefits for CAPEX and life-cycle exploitation costs are still very favourable. More critical were small projects or so-called plant changes, normally directly paid out of the exploitation budget, which were meant to abandon ergonomic misfits existing in plants in operation. Justification of such investments was often done on rather soft grounds, based on a kind of common sense and understanding rather than backed by economic or other calculations. It was there were the study team concentrated themselves. It was believed that a model able to discriminate between the justification of these type of exploitation costs or not, could certainly also be used for the larger grass roots or brown field projects. Execute the Ergonomic Construction Plan This plan’s purpose is to guide the construction contractor about installing “field run” equipment which is not always shown in the physical computer models, but only in the functional models. This concerns mainly “field run” installed items like small bore piping, lighting fixtures, secondary cable trays etc. The plan normally includes : • inserting ergonomic requirements into standard paragraphs of contracts with installation contractors, including procedures how to handle diagnosed misfits • awareness sessions with on site contractors. • use physical (3D) model on site for reference • execution of “ergonomic verification rounds”. Benefit Areas As costs can normally be estimated up front on basis of scope and hours, the team first concentrated on the benefit areas; three levels of benefit areas were established. The high level of benefit areas were defined at stakeholder level, where a rough definition of a stakeholder is that this is anyone or any group sharing the costs and other disadvantages and/or the benefits and other advantages of the business. Evaluate the application of human factors engineering The human factors engineer, the project manager and/or client’s maintenance manager normally will decide to evaluate the successes or failures of the ergonomics program during the post-implementation period. In figure 3 below a graphic representation is given of the high level benefit area’s in relation to the main stakeholders. 122 Relation to stakeholders Safety Operability shareholders & clients personnel Health society Maintenance Environment Legislation government Reliability Labour turnover Quantify or rank Figure 3 This cross-reference benefit table, given below in figure 4, is an example how benefits are ranked. A third level of benefits are long checklist, belonging to each of the second level benefits on the left hand side of figure 4. This third level of benefits are of great help to identify benefits, which are then classified in the matrix shown below. The next level was determined by investigating the benefits, tangible or intangible, within the main (high level) benefit areas. It appeared that many second level benefits were found to benefit more than one of the main benefit areas. A cross reference graph was constructed, which became the foundation on which the benefit identification process was built. 123 Figure 4 124 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 operationsmaintenancereliability safety Saving time/human resources Saving product Waste reduction Reducing/preventing errors Reducing/eliminating physical/mental stress Reducing training costs (requirements/time) Improving the quality of the end-product Preventing damage/risk to plant Making operators’ inspection rounds more effective Improving maintenance quality/life-cycle extension Parts savings Saving on hoisting/transport costs Saving on tools Saving on dirty work/cleaning/PPE costs Saving on workshop costs Saving on scaffolding costs Reducing the risk of trips Preventing/shortening plant shut-downs Preventing temporary capacity reductions Savings on monitoring on job-related risks Reducing unauthorised overrides of protective systems Increasing process safety Increasing operational safety Fewer control measures required Reducing the risk of accidents Preventing health-related absenteeism Reducing occupational diseases Preventing compensation claims and related internal discussions Reducing the number of employees who become unfit for work Reducing the number of days of adapted work Preventing impaired performance Improved occupational hygiene (toxicity, noise, etc.) Reduced pollution of the soil/water/atmosphere Reducing the probability of environmental incidents Reducing the number of environmental complaints Improving the company’s image/reputation Preventing/reducing notices/sanctions from the HSE authorities Improving the staff motivation Reducing the number of vacancies which are hard to fill Improving the performance of older/sick personnel Reducing demurrage no. Description of benefit health environmentlegislation labour turnover operations and maintenance organisation, own project management and the engineering contractor involved in basic engineering, detailed engineering, procurement and construction. Although in such an exercise costs and benefits are sometimes partly intangible, many tangible costs and benefits have been identified. Although the contents of the complete report can not be disclosed in this article, it can be mentioned that during engineering approximately 150 man days were used for analysis and engineering follow-up and approximately one man year for follow-up during construction. Minor costs, e.g. for making CD-ROM with animated training material for construction firms, are not included. After the identification of the benefits, the benefits need to be quantified. If the identified benefits are to a great extent feasible to be estimated, the benefits are outweighed against the estimated costs. In many cases however the benefits are rather intangible, e.g. “What is the $ value of safety ? “. In cases where no tangible figures can be derived from the benefits, the benefits are simply ranked according according to a system valuating : • the exposure class, showing the risk of exposure. This exposure class is determined taking the frequency of the task to be judged and the number of exposed people into account. • the effect level, showing the effect on people, environment, etc. should the task fail. • the total risk factor, being a ranking on basis of the exposure class and effect level. The “LOOK BACK” exercise/analysis showed (ABB LUMMUS): • Costs and ranked or quantified benefits • As mentioned above benefits with a tangible content may already simply justify the cost of ergonomic improvement in existing plant or in design. When a ranking exercise is needed only the highest risk factor is used to determine the payout criteria, which have been agreed before with management. So for intangible benefits, only the benefit with the highest classification counts, while for tangible benefits benefits ($) can be added. The payout criteria just mentioned are also dependent of the height of the costs. If payout criteria are reduced to zero a full intangible benefit has justified the costs to be made. In most cases there is a combination of intangible and tangible benefits, which justify or not justify necessary costs. The total procedure takes approximately 5 to 10 minutes. • • • Identified CAPEX saving were in the order of $ 2 million or 0,25 % of capital (it is believed that this figure is higher due to material wastes resulting from construction REDO. Additional CAPEX was estimated to be $ 60,000.- to improve operations and maintenance Identified savings during the first ten years of operation amounted to $ 0.9 million Identified cost savings during two four annual major shutdowns were estimated to be $ 460.000,A large list of intangible benefits, related to safety, health and environment. Integration of Human Factors Engineering into New Enginering Developments In figure 5 the procedure is shown in more detail how ergonomics has been integrated in a single object oriented database driven CAE system with integrated and thus consistent functional and physical design and engineering capabilities. The CAE system, CC Plant based on the CATIA kernel of object oriented design and engineering, has the availability to capture design intent and apply Knowledge Based Engineering (KBE). During a recent project using these advanced, fully Product Data Model based, techniques a plant was designed and engineered and the Human Factors Engineering Discipline was participating in a true concurrent mode with other disciplines as explained below. The tables and matrixes as discussed in 4.2 and 4.3 have not been further shown as the application and threshold levels are fully dependent on Company policy. Identified benefits for a large grass root project, implemented in an existing site. After having completed an ergonomics program as mentioned above on an $ 400 billion investment, the costs and benefits have been analysed together with the future 125 The participation of ergonomics all started with the given area for the plant to be built, because this will put the spatial constraints on the table. It can be mentioned at this stage that given typical areas for known plants and technologies normally used are not at stake, because experience with the ergonomic analysis shows that this will certainly not lead to the need for more area. 126 Figure 5 127 (workspace, firefighting, utility systems) Build 3D equipment catalog Make intelligent PEFD FEEEM Make intelligent PFD Process optimalisation Transpositions Lay-out constraint analysis optimalisation of piping and connectivity, incl OBL trenches, piperacks, ducting. safety showers, firefighting equipment, main E/I trenches/trays drain channels, utilities, standard safety distances, etc Other lay-out considerations Place equipment = final block model to start routing Define structures for piping and equipment area softboxes: lay-down, operational rounds, emergency routes, hoisting, transport logistics Operating & maintenance philosophy (work to man) (incl. lay-out safety considerations) Process preliminary block model Overall plotplan, including relationships between units, substations, FAR’s, utilities, etc , In the case of the particular project to be built at an existing plot after demolishment of a former plant, the existing residual existing buildings, etc had to be taken into account and to be used if needed and attractive (e.g. substations, field auxiliary rooms, analyser houses, etc.). In figure 5 it can be seen that on basis of the PFD an initial 3D block model was made very early during the feasibility phase as discussed before. With fully integrated intelligent 2D/3D engineering (one single database) this effort is negligible. the “final constraint analysis” necessary to define the plant’s civil “building”, including the often COMBINED soft boxes necessary for optimal piping, ergonomics or statutory demands. Only when the “building” with all its soft boxes is defined it is time to place the equipment finalised in the equipment catalogue. It is obvious of course that this exercise, as simply explained above, is not a straight or “from start to finish” exercise, but that a number of recycles, as a result of work in progress, exist to make further optimalisations. The procedure shows how this preliminary block model, after it had served to save some 2 to 3 % on capital investment during the process optimalisation, is used to define further refinements. On basis of the analysis based on the FEEEM matrix, demands are being defined to equipment on the one hand and detailed operating and maintenance (life-cycle) philosophies on the other hand. It can be noticed from the figure that the FEEEM ® design analysis is done in a concurrent mode with the development of the PEFD’s and that some constraint handling between ergonomic, operational, maintenance and engineering demands is already taking place at that moment. In fact at the right moment, thereby excluding a number of engineering recycles or even worse.ending with a less optimal design. Although the suspicious reader may doubt the efficiency of the procedure it can be said that, due to the fact that the approach is very structural and professional, considerable time is saved, not only during the procedure itself, by avoiding many conventional and ‘out of sync’ recycles, but especially by avoiding a lot of recycles during the later detailed engineering. It should be mentioned that apart from the defined ergonomic demands on equipment and general lay-out as used in the above procedure, the FEEEM analysis also generated many detailed demands for the detailed engineering phase on piping, instrumentation and so-called ‘ field run’ (e.g. small bore, secondary cable tray, lighting fixtures, etc.) items. Ergonomic analysis (as well as other types of analysis) and the use of a data centric object oriented single database can be considered synergetic.

With respect to spatial equipment design, which at the same time (concurrently) is developed as well, the ergonomic analysis leads to demands on free areas needed around equipment and these design intents are defined as part of the equipment in the equipment catalogue. With respect to the operating and maintenance philosophies the ergonomic analysis yield spatial demands in terms of soft boxes (a technique also used in conventional 3D systems, however at a much later stage in this project), based on identified needs for lay down areas for inspection and maintenance, operator rounds, emergency routes, logical safety shower positions, hoisting and transport needs.

Dr Ian Randle, Hu-Tech Associates Ltd and Mr Ed Terry, Sauf Consulting Ltd Introduction The regulators have an interest in this area as a means to foster improved safety and environmental performance, this approach brings 2 current strands of thinking together; Human Factors (HF) input is now realised to be the common factor, in its broadest sense, of the remaining barriers to excellent safety and environmental performance. Many issues arise from an individual’s performance in certain contexts, but there remains the opportunity to include HF in the design of systems, what is sometimes termed the Man-Machine Interface (MMI). These issues have been dealt with in engineering of new plant and equipment but much of the focus has been on direct interfaces, notably control systems. F W e e s i g n a s i b h a t c o w o r k i l i t y u l d P r o è C • Facilitating the incorporation of HF into all project system characteristics. n W c e p t u h a t w w o r k a l D the The method will allow the HF consultant to consolidate the inputs and inclusions, confirm that they are appropriate and to deal with novel and innovative issues. This process therefore reflects a “bottom-up” approach for incorporating Human Factor’s considerations into the design. Fitting into the design process The HF considerations must meet the needs of the stage in the design lifecycle, so it is pertinent to reiterate what the demands of each design are, these are described below. c e s s o of The method will look to define categories of design deliverables and will also look at the importance of CAD deliverables. The method intends to outline some basic requirements that discipline engineers can then incorporate without recourse to specialist HF advice. Using this approach, whereby the discipline specialists implement HF themselves into their traditional discipline deliverables, allows the technical and management teams to identify where HF will benefit their particular areas of responsibility and also allows HF considerations to benefit from their expertise and their specialist activities. Implementing this process will, in addition, spread the awareness and understanding to other technical and management disciplines. D Raising the understanding importance of design, and This paper presents the outline of the method currently under development and which is the subject of an industry proposal. The paper describes the steps to be taken to facilitate or support individual engineering discipline contribution to include Human Factors in the traditional deliverables of the design process for oil and gas installations. There remains an alternative approach; typical design deliverables and activities prepared or undertaken during the design of an offshore oil and gas platform are the mechanisms by which design decisions are generated, reviewed and implemented. Individual technical and managerial discipline specialists can themselves consider and incorporate (or not) solutions for areas where HF issues should be key. The project team considering these issues can then note the solution of the issue and the manner in which the solution can be incorporated. 4 • e s i g n i l l è F H 131 o E w w E D w i l l r k o è i t D e t a i l M D e s i g n a k e i t w o r k ! It is a base assumption of this method that the CAD model can function as the main vehicle for collating and consolidating HF inputs. The relationship to the information held in the CAD model to each of the above design stages must also be understood carefully. The information required and available at each stage contains varying detail and is based on varying uncertainty. The HF issues must recognise this evolution of data. Understanding the key objectives of each design stage is paramount. The inclusion of HF must be targeted precisely to meet the overall objective of the design stage being undertaken. This paper has proceeded on the basis that the above objectives hold true. The potential HF inclusions are detailed further in the tables later in this paper. The key to the successful implementation of this approach is to have a clear definition of the design phases, the related deliverables and their dependence upon the CAD model. Further detail on the objectives of each of the design stages is contained in the figure overleaf. 132 133 • Schedule • W eight • Cost • Coarse risk ranking of options • Demonst rate selected concept is ALARP • Select concept (using inherent safety principles) • Identify design options D evelop and justify selected concept D evelop a range of studies • D evelopment options ident ified è C o n c e p t u a l D e sign F e a sibilit y FEED • ALARP process • Set Performance Standards • Eliminate and prevent hazards • Identify / assess hazards Confirm design of chosen concept è 4 What is the design pr o cess? • Confirm risks a re ALARP • Confirmation of Performance Standards • Reduce and mitiga t e hazards • Confirm hazards assessment Specify & purcha se è D e tail D e sign The issues defined in the figure above also serve to reiterate that much more influence is available early in the design phase. It should be noted at this time that this paper does not address project stages beyond design. 4How is safety incorporated into the design process? D esign activities T he design process Safety activit ies T he safety process Iterates towards design goals Iterates towards safety goals aspects of safety can be successfully integrated into the design process but some aspects actually benefit from remaining independent. As education and awareness of safety has improved, the ownership of aspects of the process has and should be taken over by others with a direct impact on the outcome. The skill is to balance which tasks fall into which category. A distinctive attribute of the method proposed is the manner in which the inclusion of HF issues is undertaken. To illustrate this approach, a traditional view of implementing safety has been set out above. It can be seen that traditionally, the safety process tends to run in parallel with the design process where the activities within the design and safety processes inform each other. Each parallel process encompasses iterations that progress towards the defined goals being achieved. The figure above reinforces the concept that design and safety are rolling iterations. It must be realised that not all information will be available early in a project or will be available with acceptable levels of certainty. It is our contention that the engineers responsible for that information may be the best ones to make the judgement of what they can demand and use by way of HF information. It is our suggestion that there is an opportunity for HF studies to develop an integrated process at this point in the evolution of HF in design. The potential for merging HF directly into the activities of other disciplines within the design process is in our view even greater and may even precede the incorporation of the safety process. This approach could then build on the experience of the safety teams where some 134 4 T h e D esign Pr o cess is St aged 3 In t h e ear ly st ages, Feasibilit y and C o ncept u al, it is open to influence and change 3 T h i s is w her e H F input w ill be m o st c o st -effect ive, but w here least effort is undertaken The figure above summarises and emphasises the points discussed in the previous section.

The incorporation of HF has often been through the safety discipline and has focussed on major hazards (as required by the Safety Case). There has been more emphasis on high profile HF usability issues such as control room layout, access to large valves and handling access for equipment replacement. reporting requirements. Thus it should be noted that the key customers for reporting only are the regulators. Linking HF to deliverables In order to execute their projects effectively, engineering contractors have planning systems that have been built from lists of typical project deliverables and activities, these listings form the basis of a planning network that governs the smooth running of the project. A typical network will show the activities listed by discipline and it will identify the inputs and outputs for these activities. This information will be compiled into a detailed planning network. The remaining 2 points in the figure above are self evident and reflects the often inadequate feedback mechanisms between operations and design. The paper discussed earlier the reasons for deliverables. For many years the industry has produced deliverables for reporting, contractual fulfilment and passing on information, with fabrication, construction, installation, hook-up & commissioning and operations being the real customers. It has been a trend of recent designs to reduce unnecessary work and a success has been to simplify The planning networks have changed in character over the last few years and now tend to deal in a more focussed fashion with 135 It is therefore key to; activities rather than individual project deliverables. For example the main deliverable is the 3 dimensional model produced by the CAD system. In many design contractors the piping and layout discipline holds ownership over this model with other specialists contributing as their skills and knowledge demand. So in this case, the planning network defines the contributing activities but would register only one deliverable. The proposed method will need to ensure that project personnel work to the guidance or protocol developed. This means that the method must be demonstrably easy for them to implement. The method must therefore identify the benefits arising from the inclusion of HF during each activity and where in the project lifecycle that benefit will be felt. This will entail identifying the differences that HF will make in content and form to the outputs of each activity and then assessing the benefit that has accrued. It may be that the benefit is not felt in the immediate output of each activity but needs to be consolidated with other activities and outputs before some benefit can be identified, this “roll-up” effect will also be reviewed as part of the exercise. • Collect existing and typical planning schedules and other supporting information • Identify the areas where HF should and could be considered in the activities on those schedules • Identify the benefits that may accrue, using a wider and critical forum to review those benefits • A more tentative step will be to benchmark the value added from HF so that the worth of the activity can be demonstrated This information will enable appropriate areas to be listed where HF analysis can contribute (given the quality of information on the project at that time) and will facilitate the generation of a checklist in matrix form to show where HF contributions can take place and what they would contribute. In addition, the activities will need to be classified by their position in the project lifecycle, the figures below and the tables overleaf identify some considerations. 4 Feasibility D esign and H F input F e a sibilit y Gener ic H F T asks • • • • • System Requir ement s A n alysis Funct ional Analysis U ser Requirements A n alysis Ident ify all U ser s and St akeho lder s Ident ify T asks and H uman Interventions 136 4 Conceptual Design and HF input C o n c e p t u a l D e sign Gener ic H F Tasks • A llocat ion of Funct ion • Manpo w er Planning • Task D escr ipt ion and Synthesis • Human Fact o r s Specificat ion 4 FEED a n d D e t ail D esign a n d H F in p u t G e n e r i c H F T ask s FEED & D e t a il D e sig n • W o r k st at io n d esign • E q u i p m e n t d esign • H u m an Er r o r A nalysis (fo r Q R A ) • U ser M anuals & T r ain i n g 137 Engineering Design Stage Feasibility Key Tasks • • • • • • • Conceptual Design • • • • • • Detailed Design • • • • Human Factors Tasks Define basic process from reservoir fluids Confirm location & orientation Estimate basic size (footprint) Estimate basic weight and organise lift vessels Determine suitable structure for support (or mooring if a vessel) Identify coarse import & export requirements Use benchmark accommodation sizing (i.e. comparative platform types) • • • • • System Requirements Analysis Function analysis User Requirements Analysis Identify Users and Stakeholders Identify tasks and human interventions Confirm process requirements and specification Fix orientation, footprint and location Reduce uncertainty on weight & therefore on structural requirements Confirm accommodation and survival craft sizes Identify long lead purchase time equipment and determine preliminary specifications for them Confirm capacity and type of import/export arrangements • • • Human Factors specification Allocation of function Manpower planning – numbers, job functions Task description / synthesis Translate process requirements into detailed specifications and purchase orders for equipment Confirm and freeze weight if necessary, buy steel and confirm fabrication arrangements Place sub-contract for accommodation unit and place purchase orders for any related safety equipment Set in motion, complete purchase and QA programmes and arrange systems for material delivery to site for building. • • • • 138 • • • Equipment / Interface design Task design Workplace / workspace design Human error and reliability analysis Manpower planning - job definitions, teams, organisational structure, skills and training needs Design of user manuals / training programme Construction Fabrication / • • • Testing Commissioning & • • • Operation Maintenance / • • • • • • • Allocate contract & set in place progress monitoring arrangements Build main steelwork in-situ, add larger modules and equipment packages (having arranged delivery).

The CAD model is the most powerful vehicle for illustrating the final product. It provides a (relatively) realistic facsimile of the plant. Other information can be attached to items on the model, so that other engineers can retrieve information based on layout and equipment location. It is our proposal that added into these demarcations, each individual discipline attach the HF information relating to issues under its control. The model can be constructed in stages or layers to illustrate the construction, models have been used to track material on its way to the fabrication site, e.g. structure that was in place and built showed as one colour, material that was ordered and on its way was another colour, and material yet to be bought (i.e. where most flexibility still existed) would be a third colour. 139 Reference information example standards from the military, nuclear and aerospace industries. The inclusion of HF has some precedents from other industries.

The discipline engineers will have the advantage of seeing benefits deriving from their own actions in a specialist area with which they were not initially familiar. This in turn will build their understanding and awareness of HF issues. The guidance should provide a toolkit for discipline engineers to use. The toolkit should be designed to be readily used by many discipline engineers with a low starting awareness of HF. 4 W h a t i s t h e g u i d a n c e p r o p o sin g t o d o ? 3 Pr o v i d e a t o o l k i t f o r d e sign e r s t o a p p l y H F c o n si d e r at io n s t o t h e ir o w n d e l i v e r ables & act ivit i e s 3 Illu st r at e t h e b e n e fit s ar ising fr o m an ear l y c o n sid e r at io n of H F 3 Im p r o v e e d u c at io n and aw ar e n e ss o f H F am o ngst o t h e r d isc i p l i n e specialist s Benefits of the guidance significant and will follow the points in the figure below.

By adopting the bottom-up approach we consider that the disciplines will deal with many lower hazard issues as well as those associated with major accident hazards. The model should be integrated into the project life cycle, and the HF issues contained in the guidance should be appropriate to the stage in the life cycle. Our conclusions are summarised in the figure below. 4 C o nclusions 3 M o del addr esses gaps in H F input int o d esign 3 Individual engineer ing disciplines can t ake co n t r o l o f H F in their o w n pat ch 3 The form of deliverables facilit ates the inclusion of H F as never b e f o r e 3 The focus is o n m aking it easier for discipline engineer s t o integr ate H F int o t he pr o ject 3 There ar e benefit s fo r t he user , the operat o r , the const r uct o r and the r egulat o r QUESTIONS AND ANSWERS SESSION Question - Ian Loughran, Phillips Petroleum In a previous life I had experience of the use of 3D CAD modelling on a project that I worked on as a project engineer. However, my recollection when we used the CAD model, from the point of view of human factors I think, is that we didn't really know what we were looking for when we were going through it, because we're all engineers basically. What's your experience in trying to educate, and perhaps providing check sheets etc., so that people can make the most of the tools available? Question – Dr Ron Gardner, HSE A question probably to both speakers really, but especially Ian working a sort of bottom-up approach. I just wonder about the language you use when you talk about human factors or health to engineers because I've found that on occasion a problem. I come in to this as an occupational hygienist and I find we talk different languages, sometimes even using the same word to mean entirely different things. I just wondered if you've come across that, what sort of views you have and how you might tackle it. Answer - Ed Terry, Sauf Consulting Ltd Perhaps I can answer that. I think one of the things we don't use with the CAD model is the visual aspect and I was interested you immediately said ‘should we use some sort of checklist’? An example I'd seen my old team use was on aligning gas detectors. As you are probably aware, you fit gas detectors over offshore platforms and they don't always look at the piece of kit that you are supposed to be protecting. What they ended up doing was publishing a pamphlet of views that the gas detectors should see, straight out of the 3D model. So, when it went to the fabrication yard, the guy who was fitting the detectors just had to line up his eye along the axis and if he saw exactly the same picture that he had in his pamphlet, it was looking at exactly the right Answer - Dr Ian Randle, Hu Tech Associates Ltd It's a point very well made. It's got to be framed in terms that are understandable. I think that's very much the focus of the project using terminology, their terminology and not our terminology, making it user friendly for the discipline engineers. It’s kind of practising what we preach as human factors professionals. It’s about the user-centred design for the information we're providing for that set of users. The secret, the solution? Well you've got to get in amongst them. You’ve got to learn their terminology and you've got to get integrated and trusted and get critical feedback from what you are presenting to them and ensure that it does meet their needs. 141 chap operating the valve manually. There is that level of capability and so that will help to guide us. We wouldn't have to wait until he's actually doing it, to see the posture and the hazards. We could do that at the CAD stage. piece of equipment. Now that's an obvious example. I'm sure there are many more where we could actually make use of the visual aspect of the model. As you know models are extraordinary these days, the detail is phenomenal. Comment – Mr Harrie Rensink, Shell International There is also the economic rule - don’t think that with the pace that we are having to do today in project management that during a review you can change valve layouts. So, before detailed design starts you must have made clear to the layout designers which of your valve layouts should be a hundred percent according to the rules and which of them we can more or less forget. In the old days we were told we will design all valves according to the rules. That is an unrealistic statement because then our plants would be from Aberdeen to Edinburgh. A typical ergonomic activity would be to identify real critical human machine interfaces and one of them should lead to identification of what we call category 1 valve layout. That information should be passed over to the layout guy so that he can really work with it before the layout is frozen. The layout is frozen at the end of project specification. Keep in mind that everything changed after freezing of your project spec will result in extra rework and we can't afford it. So, everything you think is relevant for the design should be brought up before that’s finished. I think the trick is to try and pick something that's visual to help the guy who is actually fitting it together and then help the guy who is doing the job. That's why we think that's going to be such a good vehicle. It has been used and the move is there but I think with recent turn down in activity it might just need an extra little push back again to get back on track. Comments - Mr Harrie Rensink, Shell International May I add some remarks. First, the model is as bad as its input. In the old days we had a plastic model, now we have a 3D model. Fine. Something more flexible but it's as bad as its inputs. Now I'll ask the second question to you and that is, you didn't know where to check against. Now I'll ask you if you are a process engineer or instrument engineer? (Ian Loughran - process engineer) That's good. So where do you check your design against then? Against your process engineering spec’s I assume. So the answer to what would you be using during model reviews is the spec’s that should have been developed/implemented in an earlier phase. That's the way to do a proper design. It's interesting that, now we are talking about ergonomics or health or whatever, you think you can do this with a check list instead of following your own discipline engineering process? Being at least one of the steps produce specs. And in another remark because I like process engineers very much, you will see that one is one of the co authors of my paper. I even think that's its very important to have these types of activities integrated in the process engineering process because it's the same type of analysis and it should have been the same type of deliverables. It also makes use of the same type of input being a process flow scheme, at least in our approach. So please address this type of activity the same as you would do with any other engineering discipline would be my final statement. Question - Mr Colin Burgess, Shell Expro One for Harrie really. How do you sell the benefits of human factors engineering to a main contractor who's responsible for engineering, procurement, installation, commissioning and fit for purpose? Answer - Mr Harrie Rensink, Shell International That's indeed a problem. If you really want to have the proper answer you should have been able to identify all the goals of the various stakeholders. I touched on the fact that sometimes an engineering contractor’s goal is quite different from an operator’s goal. It may look a little bit basic too. I'm not asking engineering contractors to do more than they should do, but there are differences in goals. What we have learnt is that, if there is a contract type that enhances ‘right first time’, then a contractor will be willing to get operators, maintenance and human factors engineering activity up in the process (80% of misfits during detailed engineering are related Comment – Dr Ian Randall, Hu Tech Associates Ltd Just one tiny bit to add to that building on what Ed has said. The complexity of the CAD models now could mimic the posture of the 142 to operability and maintainability). In other words, look into the contract - the type of contract - and that will guide you at least to check the willingness of the contractor. At the end of the day if you look at our figures related to Capex and related to total cost of ownership reduction, the plant owner should be the driver of all this type of activity. But, the type of contract is important for how the contractor will act and react on proposals. Does that help you a little bit? Answer – Mr Colin Burgess, Shell Expro Yes, thanks. Comment – Dr Ian Randall, Hu Tech Associates Ltd Can I just add something very quickly to that. I've been involved over the years in producing responses to human factor specifications from operators on behalf of design houses. Quite often those specifications can require a lot of detail but are not very specific in what they require and obviously one does one's best. What strikes me is that there is then a gap in terms of the enforcement of that, the verification of that, later on. I don't know if it is just that I've not won that sort of work. But I've not really been involved in verifying that what was asked for was actually being delivered from the human factors perspective. 143 144 DAY 2 AFTERNOON SESSION SESSION THEME – PHYSICAL, CHEMICAL AND BIOLOGICAL AGENTS – CASE STUDIES 145 146 EXPERIENCE FROM SUPERVISION OF OPERATOR COMPANIES' ASSESSMENT OF CHEMICAL RISK. Mrs Anne Myhrvold, Mr Sigvart Zachariassen And Mr J A Ask, Norwegian Petroleum Directorate, Stavanger sampling data, assessments. Abstract but very few qualified Additional motivation for starting this supervisory activity was the data on accidents, incidents and work related diseases NPD get from the oil companies. These data showed a significant number and a variety of different diseases related to chemical exposure. Norwegian regulations relevant for petroleum activities do not have specific requirements to risk assessments of chemical agents, like the COSHH-regulations in the UK. The EU council directive, ”Chemical agents at work”, includes requirements to risk assessments and this will be implemented in Norwegian legislation later this year. The requirements for chemical risk assessments are found in the “Regulation relating to systematic follow-up of the working environment in the petroleum activities”. The EU council directive, ”Chemical agents at work”, includes requirements for risk assessments and this directive will be implemented in Norwegian legislation later this year. In 1999 the Norwegian Petroleum Directorate (NPD) performed a supervisory activity of chemical risk assessment towards the main oil companies operating on the Norwegian continental shelf. The joint approach for the activity was to let the companies perform specific risk assessments, while NPD followed the process from the identification of assessment objects until final reporting, communicating and implementing of measures. Each company was evaluated towards their ability to perform chemical risk assessment, within a holistic chemical management strategy. The goals and the approach The goals for the supervisory activity were to contribute to improve the companies’ ability to perform and follow up chemical risk assessment for the working environment and to generate knowledge related to chemical exposure relevant for the petroleum activity. NPD also wanted to contribute to experience and knowledge exchange between parties in the petroleum sector. NPD’s supervisory activity showed variation between the oil companies in all of the aspects that were evaluated. We observed weaknesses in identification and ability to give priority between critical items, insufficient specialist competence, weakness in methodology and strategy, and lack of management commitment and employee involvement. This paper presents NPD’s experience from the supervisory activity and discusses generic requirements to chemical risk assessment methodology. Each company performed one or a few risk assessments relevant for their installations and ongoing activity. The supervisory activity started with a process in the companies to find out for what area and activity they needed to perform a risk assessment. NPD followed the assessment process starting with the identification of areas and tasks, the planning phase, and continued with the performing and reporting phase. At the end of 1999 the companies presented the results from the performed risk assessments to NDP. We gave feedback to each company. Introduction In 1999 the Norwegian Petroleum Directorate performed a supervisory activity on chemical risk assessment towards the main oil companies operating on the Norwegian continental shelf. The background for the NPD activity was experience from performed audits and verifications within working environment where we observed several activities just on 147 Areas and operations covered by the oil companies’ risk assessments Another connected aspect to the problems with performing risk assessments was related to insufficient resources and specialist competence. The specialists needed in chemical risk assessments are occupational hygiene professionals and occupational medicine specialists together with personnel with relevant technical and operational background. Norsk Hydro: • Re-injection and other treatment of cuttings (Oseberg) • Hydrocarbons relevant for operation of offshore process plant • Chemical treatment in offshore process plant (Saga) BP-Amoco: • Oil based mud in shaker and mud-pit areas (Valhall) • Relevant NDT-activities Norske Shell: • Various cleaning operations Statoil: • Mud mixing and mud treatment (Statfjord C) • Operation and maintenance of amineplant for CO2 removal • Thermal breakdown of polyurethanecoatings Exxon: • Mud and cement mixing (Jotun B) Phillips Petroleum Company Norway: • Use of biocides in drilling and production • Thermal breakdown of polyurethanecoatings We noticed lack of management commitment and employee involvement during these processes in most of the companies. This aspect we specifically looked for in this supervisory activity, since both involvement and commitment are success factors for achieving improvements. Positive experience was also observed, for instance the good processes in and between the companies, where monitored data was shared, similar problems were discussed etc. This is appropriate to one of the goals of this supervisory activity: to contribute exchange of experience and knowledge between the companies. Generic requirements for performing risk assessments The experience from this supervisory activity indicated a need for practical guidelines on how to perform chemical risk assessments. NPD is about to finish a report summarising our requirements and expectations to risk assessment and risk management relating to chemical agents. The report will cover principles and practises of the complete quality loop (control-loop) for each step in the assessment process, from identification of potential hazard, monitoring and modelling of exposure, risk assessment and evaluation and decisions of preventive measures. NPD’s experiences with the supervisory activity The experiences from the supervisory activity showed variation in ability and quality between the oil companies’ in all of the aspects that were evaluated. Many of the companies had problems with performing a chemical risk assessment. The supervisory activity started with a process in each company where they identified tasks and operations suitable for performing a risk assessment. We found that there was not a systematic approach to identify and prioritise between the critical items. This, together with the fact that many of the companies did not have a methodology established for performing risk assessments of chemical exposure, resulted in serious starting problems for some of the companies. Some companies used risk matrixes alone as the “method” for risk assessments, while others had good developed methods in use. The uncritical use of risk matrixes demonstrated the need for some companies to gain knowledge of risk assessment methodology. The coming report can be used as a guideline for the different companies to ensure a good way of performing risk assessments. The report tries to give a holistic view of the requirements, the needs for resources and competence and the criteria for management commitment and employee involvement. A successful risk assessment and risk management does also depend on co-operation between competent participants. To make this co-operation possible it is important to know each other’s competence. Further on it is substantial to know one’s own limitation and to have competence to order additional resources. 148 like a specialist does. I don’t think it is possible to transfer this kind of competency throughout the company. It is important to stress the need for specialist competence. But the worker involvement plays an important role to ensure a “realistic” risk assessment. We saw that some of the companies had good worker involvement in the risk assessment. The activity was used to visualise the risks and need for preventive measures, and in this way “educating the company” and I think this will raise awareness of risk assessments. It is important to have both specialists and worker involvement in the risk assessment activity. Another aspect that is essential for performing good risk assessments is to pay attention to the quality control in the assessment process, for instance to verify the data and to qualify the laboratory used. Of other generic requirements we mention the need for transparent methodology and the necessity for documentation of the risk assessment and the whole process. The coming report also states the hierarchy of preventive measures to reduce the chemical risk. QUESTIONS AND ANSWERS SESSION Question - Dr Ron Gardner, HSE Anne, we’ve spoken before about our parallel experiences with hazardous substances. In much of what you say I can see parallels with what we’ve found offshore. Right at the end though you mentioned preventive measures, something close to every occupational hygienist’s heart. Just what did you find in practice because one of the things we noticed very much was there was a great tendency to look at something, say yes there’s a risk, here’s your personal protective equipment. What’s your experience? Question – Tony Parkinson Noble Drilling, for Texaco I’m surprised that you say they’re using oilbased muds again. We thought we’d reduced that and cut it down. Is that correct? Answer - Mrs Anne Myhrvold, NPD Yes. There was reduction in use of oil-based muds because of both working environment or occupational health and the environment outside. But with this new technology, reinjection, we have seen oil-based mud is coming back again. Answer - Mrs Anne Myhrvold, NPD Very much the same unfortunately but still they are paying more attention to it. I think we are moving upwards to try other things to avoid personal equipment. Question - Mr Graham Cowling, Acoustic Technology Ltd You mentioned that the risk assessments seemed to require a specialist to carry out the assessments. Was there any evidence of any attempt to transfer competency in doing those assessments to the offshore workforce and do you think there would be any benefit in raising the awareness of risk assessment issues if that happened? Question – Edmund Brookes, BROA I noticed in your presentation you indicated you were going about the process in an unusual way and following on from that you were having your own conference or seminar, presumably in Stavanger fairly soon. Open to all? Does that include people from this side of the Norwegian/ UK divide? Answer - Mrs Anne Myhrvold, NPD Well I think it’s important to have different people in the process but of course the specialist has to have a central role in this risk assessment. Dealing with the aspects of worker involvement, employees do not have the competence to perform risk assessments Answer - Mrs Anne Myhrvold, NPD If you speak Norwegian - just come. You will have to understand Norwegian. 149 150 MEASURING OCCUPATIONAL EXPOSURE TO HAZARDOUS CHEMICALS IN THE OFFSHORE INDUSTRY Mr Lindsay Ross, BP, Dr Ahsan Saleem, Offshore Safety Division, HSE and Mr Stuart Whiteley, Shell UK Exploration and Production necessitated the need for further investigation. As a result, an exposure survey was carried out jointly by HSE and UKOOA to assess the impact that the lowering of the MEL for benzene would have on the offshore industry (HSE, 1999a). Occupational exposure to hazardous chemicals is a daily occurrence for many workers in the offshore industry. To manage this risk, it is important to have a good understanding of the nature of chemical usage offshore in terms of the substances used, the potential for exposure and the resulting health risks. Following the extension of COSHH to apply offshore in 1995, UKOOA’s Occupational Hygiene Working Group commissioned a review of chemical exposure data collected by its members. The objectives of the review were to identify deficiencies in the available database, provide information to support industry-wide standards and help to prioritise further exposure monitoring work. The review identified a number of deficiencies in the available exposure data and recommended further work to develop the offshore occupational exposure database. As a result a working group was set up between HSE and Industry to develop and carry out exposure surveys on an industry-wide basis. The first two areas identified by the working group for further work were the measurement of occupational exposure to Benzene and Drilling fluids. Over 90% of chemicals supplied offshore are used in drilling operations. Drilling fluids are complex chemical mixtures designed to have specific properties under very specific drilling conditions (HSE, 1999b). Aerosols and vapours generated from the use of drilling fluids are associated with a number of illhealth effects including eye and respiratory tract irritation. Also, skin contact with whole muds and some individual components has been associated with dermatitis. Previous exposure assessments have used a variety of sampling methodologies and various exposure standards. There was a lack of personal exposure data but the range of available static sampling results indicated the potential for significant personal exposure. In view of the potential for exposure and the limitations in the available exposure data, it was decided to standardise the sampling methods and to carry out a survey of occupational exposure to drilling fluid vapours and mist. Benzene is a natural component of crude oil and unrefined natural gas (0.1-3%). Epidemiological studies have demonstrated an association between benzene exposure and the development of leukaemia and benzene is a regarded as a human carcinogen. However, no threshold for carcinogenicity has been demonstrated and it is not possible to establish a level below which risks to health cease to exist. This led to the introduction of a Maximum Exposure Limit (MEL, 8-hour TWA) in the UK of 5 ppm in 1991. The first amendment to the Carcinogens Directive, which was adopted by the European Commission in June 1997, called for revision of the MEL for benzene over a 3 year period. The UK implemented the directive, in December 1998, with a phased reduction of the MEL for benzene from 5 ppm to 3 ppm in June 2000, and from 3 ppm to 1 ppm in June 2003. Although, the available exposure data did not indicate a significant problem offshore the proposed reduction in the occupational exposure limit for benzene and some limitations in the existing exposure data References HSE 1999a “Occupational exposure to benzene, toluene, xylene and ethylbenzene during routine offshore oil and gas production operations”, HSE Offshore Technology Report - OTO 1999 088 HSE 1999b “Drilling fluids composition and use within the UK Offshore drilling industry”, HSE Offshore Technology Report - OTO 1999 089 QUESTIONS AND ANSWERS SESSION Question - Andy Curran, HSE You referred to a lot of environmental sampling. Has any thought been given to biological sampling because obviously for contamination of the skin, your environmental sampling is not going to reveal that. Nor will environmental sampling say what they were exposed to. 151 welly boots to be filled with mud, things like that and a general awareness. In terms of biological sampling, perhaps Dr John Cocker at the back there can bring us up to date with biological sampling for these sorts of issues? Answer – Stuart Whiteley, Shell Expro In terms of the dermatitis hazard, I think that’s well understood and the control methods are actually in place for that.

Question - Tony Parkinson, Noble Drilling, for Texaco Is legionella caused by inhalation or by drinking contaminated water? Comment – Dr Ron Gardner, HSE I can add to that. I think a better phrase would be ‘people at higher risk’ rather than ‘at-risk grouping’ but that’s a semantic point maybe. I want to emphasise something though. Mark has talked very specifically about legionella. Offshore you take on the water supplier’s responsibility so don’t take the comment in L8 (Legionnaires’ disease. The control of legionella bacteria in water systems. Approved Code of Practice and Guidance) to mean that you can’t stop sampling for other bacteria including coliforms or that you can’t stop doing chemical analysis. You have that responsibility under the Management and Administration Regulations. Answer - Mark Brown, Commercial Microbiology Ltd Inhalation primarily, leading to colonisation in lung tissue. Question - Tony Parkinson, Noble Drilling, for Texaco Why does it affect smokers? Answer - Mark Brown, Commercial Microbiology Ltd Primarily I presume because of the state of their lungs; a weakened immune response I’d imagine. Question - Bill Morgan, Shell Expro You mentioned this at-risk. Usually in an atrisk group there’s usually some prevalence within an at-risk group. I’ve worked for Shell Expro for 22 years. We’ve not had a case of legionella in 22 years. The Public Health Laboratory system has no data whatsoever on any offshore oil worker suffering from legionella. Would you like to respond? Could I also add that if you take those samples, (it’s a plea really), often people look at the sample results and say ‘we’re within spec’ and they get put in a file. Look at the trends. Iron in particular Mark has mentioned – don’t look at a one-off value. Look at the trend, because that will tell you a great deal, that one measurement, about the condition of your system and the chances of you developing bacterial growth, not just legionella but other things as well. It’s a plea on my part really. Answer - Mark Brown, Commercial Microbiology Ltd I think you’re right. There have been rumours and speculation that it does occur offshore, but as you say there have been no documented cases of Legionnaires disease offshore. But, I think we should just be aware that it’s got potential to occur and cause disease if we don’t control it. Think of the recent BBC case with cooling towers. I think with cooling towers some of the main problems are due to the fact that we’re dispensing perhaps a large number of organisms into the atmosphere. With the BBC case it was found that for individuals that were actually walking past the BBC, perhaps a thousand of those individuals wouldn’t be affected but one would. They traced all the cases of Legionnaires disease back to people that had walked past the BBC, purely because they were being exposed to aerosolation from cooling towers. Question - Mark Gibb, Blowout Magazine Is the necessary equipment available and are the necessarily qualified personnel available to carry out the tests that are required on all installations? Answer – Mark Brown, Commercial Microbiology Ltd I think it’s a difficult one but the operator has a responsibility to be performing these risk assessments but not necessarily a responsibility to actually be doing the sampling itself. This could be given out to third party individuals. Qualified legionella risk assessors can come in and do audits for you. So it’s not necessarily personnel on board that need to be doing the sampling. 156 IMPLEMENTATION OF THE NOISE AT WORK REGULATIONS, OFFSHORE Mr Curt Robinson, Acoustic Technology Ltd Introduction implemented; this requires an authority and access to a budget that the medic/safety officer often does not have. If the responsible person is not identified within the management procedures then it will default to the OIM as opposed to the competent person. If the exposure assessment identifies a particular area that gives rise to a significant proportion of the risk to the asset, then it is the responsible person who is required to ensure that that risk is minimised to as low as reasonably practicable. This is not an impediment to assigning the responsible task to the competent person, however, they must be authorised with the necessary authority, support and funds to initiate improvements/actions where necessary. After the implementation of the Noise at Work Regulations (NWR) offshore through SI 1997/1993 “The Electricity and Noise at Work Regulations” in January 1998, the initial emphasis was to ensure that assets had carried out a noise exposure assessment and had begun a hearing conservation programme. In the past 18 months most of these assets have reached the limit of the bi-annual assessment period and a further survey has been completed. During this latest survey more emphasis was placed on an audit of the management procedures in place and the general “health” of the hearing conservation programme. This paper summarises the findings found during these latest assessments and highlights the general strength and weaknesses of most hearing conservation programmes. Assessment (Regulation 4) ATL’s noise exposure management system assessment programme (NEMS) has been installed on the majority of assets within the UK sector. The programme, which is intended for risk assessment, assesses the long term exposure of personnel (work patterns are assessed typically over a two week shift – with the sanction of the HSE) whereas the regulations set their criteria based on daily exposure, for highly variable tasks the exposure may also be averaged over a week. Policy The cornerstone for ensuring that a hearing conservation programme is likely to be successful is a management policy and procedures that outlines lines of responsibility and actions to be undertaken by identified personnel. Most assets, in the main, have an acceptable policy and procedures in place. Two common weaknesses are that it is not always to hand and that it does not identify persons within the lines of responsibility. Most notably, the “competent” person is also considered to be the “responsible” person for the implementation of the regulations. For example: A Mechanical Technician is required to run the fire water pumps (2 off) once a week. Each pump is run for 15 minutes, only 5 minutes of that time is spent within the pump enclosure with the engine running (room noise level – 108 dB(A)): Competency vs. Responsibility It is common to find that the medic or safety officer has been assigned the task of managing hearing the conservation programme. These persons have often completed an approved training course to demonstrate their “competency” and, therefore, they largely have sufficient knowledge to carry out an assessment, advise on hearing protection and zones, provide training and information on the effects of noise and keep an up-to-date record of the programme. • The fractional exposure for this activity is 91 LEP,d. • The weekly fractional exposure for the technician will be 83 dB(A); • If there are 4 mechanical technicians within the team and each is equally likely to carry out the task then the group fractional exposure reduces to 77 dB(A). Over the long term, therefore, ensuring an equal rotation through the task, reduces the risk to a minimum level. It is still important to remember that for the day the task is carried Competency, however, does not infer responsibility. A “responsible person” has the responsibility to ensure that the programme is 157 Noise Exposure Reduction (Regulations 6 and 7) Most modern assets (built within the previous 10 years) still have healthy reservoirs and, therefore, have larger budgets to work with and are open to implement noise control measures. Often these assets are looking at debottlenecking or other projects to improve the efficiency/output of the asset and it is possible to incorporate noise control improvements into these projects, thereby demonstrating continuous improvement. out, the technician will have a second action level exposure. The benefit of the NEMS system is that it provides an overall risk assessment of the asset, it identifies personnel most at risk from noise exposure and areas within the asset that give rise to that risk. This is useful when considering the practicability of noise control. In addition, NEMS normally does not include contributions from hand tools unless they are part of the job function (e.g. needle guns for the paint crew). Therefore, personnel that use “high noise” tools such as impact wrenches will significantly increase their daily exposure level. For older assets where the production rate might not be so healthy, budgets are much tighter, equipment older and noise control improvements do not appear as desirable. We believe that there are still some measures that can be implemented that can reduce the noise exposure risk and effective noise control measures need not always be expensive. For example, high noise levels within a water injection module were traced to a control valve on the discharge line of a non operating water injection pump that had not properly seated; water was flowing back through the valve. Repairs to that valve would improved the water injection system and reduce the noise levels within the module by 3 dB(A) (or in terms of fractional exposure, by 50 %). For an asset using NEMS, ATL recommends a dosimetry programme (also an HSE recommendation). The purpose of this is to verify and trend the noise exposure of specific trades, using a meter worn throughout a number of shifts. The benefits of dosimetry studies include: • Verification – particularly appropriate to borderline first and second action level cases, individuals with high second action level exposures and trades with highly variable work patterns. Another method is to implement a noise control register of all measures implemented on-board. The register can then be audited annually and used to demonstrate that the measures already incorporated are maintained and kept in good condition. • Information from dosimetry can be used to adjust and fine tune the NEMS model. • Undertaking dosimetry allows contact time to discuss noise issues with persons most at risk and maintain awareness of noise. Two case studies given below illustrate that noise control measures can be cost effective although they may not always achieve the desired goal! • Providing data on peak levels and whether the action level has been exceeded. CASE STUDY 1 An acoustic enclosure was fitted over a water injection pump. Measured noise levels increased by 4 dB(A) after the enclosure was fitted. Preliminary investigations suggest that the enclosure has been rigidly fixed to the skid, thereby allowing the large enclosure panels to become an effective radiating surface for energy transmitted through the package structure. Noise levels were not improved be leaving large apertures open on the enclosure. Isolating the enclosure from the skid with a resilient strip and sealing the apertures should improve the effectiveness of the enclosure. Surprisingly the dosimetry data does show that the 200 Pa level can apparently be exceeded regularly. Analysis has shown that this commonly occurs around traditional “break” periods. Possibly due to a heavy karaoke session in the ‘coffee’ areas, more likely though to be due to an impact on the microphone as the overalls are removed and stored in lockers. Another likely cause is the interference from radios located in the same area as the dosimeter microphone. 158 CASE STUDY 2 A JT gas exchanger located within the process module generated surface noise levels to 118 dB(A) from pipework leading from the dry gas scrubber to the exchanger. Applying acoustic insulation to this pipework, less than 30 m in length would decrease deck noise levels by upwards of 5 dB(A) and the overall asset risk by approximately 40 %. Hearing Protection/Zones (Regulations 8 and 9) • The issue of ear muffs or moulded plugs should be recorded to illustrate that the devices are replaced at the correct intervals; • It is important to ensure that hearing protection devices provided to contractors by their employers are in good condition and are acceptable for use on the asset. This is considered to be the facet of the regulations that is most closely followed, most assets maintain a minimum number of protection devices and these normally provide adequate coverage. Areas for improvement that have been noted are: One major inconsistency found across assets is the policy of mandatory use of hearing protection outside accommodation modules. The major arguments for this policy presented by the assets are: • It is considered good practice to have marked up plot plans in the coffee areas and at exit points from accommodation module, highlighting areas of risk; 159 • Hearing protectors should become accepted as part of PPE similar to the use of eye protection; • The policy is easier to enforce; • It minimises the risk of hearing decay. Health Surveillance Although health surveillance is not mentioned within the regulations it is covered within the Management of Health and Safety at Work Regulations and is specifically mentioned within the HSE guidance notes of the NWR “Reducing Noise at Work”. We believe that the arguments against are: • Compulsory use of hearing protection is not enforced by the HSE in areas below 85 dB(A); • Wearing of personal hearing protection in lower noise areas could impede communication including the hearing of PA announcements that may contain safety messages; • Wearing of hearing protection can be uncomfortable over a long period of time (especially ear muffs worn in conjunction with spectacles); • Complacency in removing hearing protection in obvious quiet zones and not replacing them for high noise level areas. “The appropriate technique for noise health surveillance is audiometry”. The important facet about audiometry is that it is the feedback loop that demonstrates that the objective of the regulations “to prevent damage to the hearing of workers from excessive noise at work” has been met. Unfortunately most audiometry is carried out by third parties, records of previous assessments are not always kept in a central database and the data is rarely audited to assess the effectiveness of the programme. It is unlikely, therefore, that any feedback occurs to enable the responsible/competent person to use the data to improve the programme. Most importantly it was understood that the HSE was against this policy because the goal of the regulations was to minimise the risk to as low as reasonably practicable without the use of hearing protection. Some assets carry out audiometry onboard, which gives the competent person more feedback on the success of the programme. ATL is in the process, with a major UK operator, of maximising the information that can be obtained with audiometric screening at the work site. Audiometry is now carried out annually and instead of trying to minimise the possibility of personnel suffering from Temporary Threshold Shift (TTS) by carrying out the tests in the morning, etc., the tests are carried out at the end of each shift in order to look for TTS. If a person is displaying TTS, it is evidence that the hearing conservation programme has failed in some way for that person, because if hearing protection had been worn correctly then the exposure should be less than that required to give TTS. The tests may not be as accurate as those carried out onshore but if a person is demonstrating worrying signs of hearing threshold decay then they should be referred to a practitioner as a matter of course where a more accurate assessment can be carried out. We believe that the implementation of this policy has become confused with the HSE endorsing the mandatory use policy on some assets whilst requesting other assets to desist; this has made the arguments against the policy difficult to defend and is an area that requires clarification. Records (Regulation 5) This is an important area, particularly for the employer, as it is through record keeping that holds the evidence demonstrating the implementation of the regulations. Most assets are good at storing copies of reports of exposure assessments and noise control studies. The main weakness is in keeping records of services provided to employees. This includes hearing protection, training and information provided. 160 80 70 % P o p u la t ion 60 50 40 68 30 20 10 22 15 13 2 3 19 0 1 4 5 H S E Ca t e g o r y Category 1 to 3: “Referral Category 4: “Warning” Category 5: “Acceptable” Example of Audiometric Data for a UK Field Assessed against HSE Criteria in 1999 smaller platforms, perhaps where it’s particularly noisy. But it is open to abuse if you do find quiet areas because people will take their hearing protection off. I would say generally it’s the lazy way out, so I would say generally we are not keen on it. It’s not something that we can prohibit as such though, but to say we think it’s a good idea, I hope that my comment reflects that we don’t think it’s a good idea per se. In this way the competent/responsible persons can be satisfied that they have implemented a successful hearing conservation programme. Summary In summary, it is believed that most assets have implemented the regulations in good faith, keep up to date with the assessments and ensure that the hearing protection provided is adequate and is used by personnel. Weaknesses include not differentiating between competent and responsible persons, not keeping records on training and information provided or operating an adequate health surveillance programme. Answer - Mr Curt Robinson, Acoustic Technology I agree. All I think is that perhaps it is the way it’s communicated to the people because it’s then been disseminated through the other assets and so forth so as soon as I say I don’t think it’s a good idea I get this feedback coming through. QUESTIONS AND ANSWERS SESSION Comment – Mr Kevin O’Donnell, Offshore Safety Division, HSE A bit of feedback on your view, or the view expressed about HSE’s view of total hearing protection zones outside the accommodation. I have come across them but to say that HSE ‘thinks it’s good’ - I’m sure you have quoted other people who say that’s not true. Our view is that, at best, it’s a rather crude way to deal with the problem. It may be appropriate on Question – Unknown speaker, offshore medic with Shell I recently attended a noise awareness course and want to know if it is true that levels are to drop by 5dBs. Answer - Mr Curt Robinson, Acoustic Technology Ltd 161 There was a European Directive a while back where it was proposed that the levels be dropped by about 5dBs. Basically, it is not so much that the first action level becomes 80 but it’s really having the actions commensurate with the second action level applying after 85dBs. Then nothing really happened from that and it met with some resistance. But it’s interesting that the European Presidency has just changed over to Sweden and there is a Vibration Physical Agents Directive that’s been on the cards for a while now looking at Hand Arm Vibration. It’s been a bit of a football. The Swedish Presidency suddenly also reintroduced the Physical Agents Directive on noise. At the moment it’s up as a proposal and up for discussions. Answer - Mr Curt Robinson, Acoustic Technology Ltd That’s something we’re hoping to look at in the next six months. We had a federal contract with BP to oversee noise management issues, so that’s where I got my data from. But ATL has done a number of measurements on all sorts of installations and it’s something that we’ll be looking at producing in the future, that is the comparisons between different types of vessels. Question - Bob Hanson, BG Group The reason I ask the question is from my own experience it would seem that when you arrive on a drilling rig that they do tend to be noisier. I know it’s anecdotal but I’d be interested if any of the drilling organisations have done any work in assessing noise exposure on drilling rigs specifically. Question - Bob Hanson, BG Group The data that you presented is from one company and it refers to fixed installations. Is that correct? Answer - Mr Curt Robinson, Acoustic Technology Ltd It is part of the legislation, that they need to I think that the effort put in by some of the drilling companies is equal to the oil installations. Because of the fact that they are small and live then yes, there are noise issues. But I’d like to think that the drilling companies are taking measures to put precautions through. Answer - Mr Curt Robinson, Acoustic Technology Ltd It’s mainly fixed installations. There are a couple of FPSOs in there as well. Question - Bob Hanson, BG Group Have you done any work and have you any data on drilling rigs and how did the two compare? 162 THE LSA FOCUSED RESULTS DELIVERY PROJECT ON NORM Mr Brian McKendrick, Shell Expro The FRD Team and Why it Was Formed item is not caught before it leaves our control. Focussed Results Delivery (FRD) projects are used by Shell Expro to bring a high-powered team to focus on a problem which has become intractable, proven “too difficult” or needs multiple skills. The team has a sponsor, usually an Asset Manager, a budget and a tight timescale. Team dynamics training is used to maximise team effectiveness. It is, in effect, a “tough nut cracker”. Shell Expro has had Naturally Occurring Radioactive Material (NORM), in the form of Low Specific Activity (LSA) scale, within its wells, plant and pipelines for many years. It has developed working procedures (Local Rules) and recording systems to manage the problem over the years. These have been developed in a “top down” way - company experts writing procedures for the workforce to apply. 4 ISO 14001, the environmental management standard, requires rigorous documentation systems, and while the NORM systems passed the inspection, the piecemeal nature was noted. A team of eleven people was set up, consisting of radiation specialists (RPA, corporate and Business Unit), plus representatives from operations, logistics, procurement, production chemistry and a decontamination contractor. All the key stakeholders were represented. A growing NORM contamination of the process plant on our platforms, both in terms of extent and activity. In effect, all of our oil producing wells and processes are NORM contaminated. NORM is also being found in service water systems. The NORM in some wells, coolers and other equipment is also growing steadily more active. The FRD Process The FRD project was sponsored by Shell Expro’s Tern/Eider/North Cormorant (TENC) asset. This in turn means that many more staff are potentially exposed to NORM. Virtually every maintenance job now has a NORM dimension. It also means an increasing burden to the business in terms of planning, preparation, delays, costs, training and record keeping. 2 The Scottish Environment Protection Agency (SEPA) has adopted a much more stringent inspection approach, particularly on record keeping, and has identified certain shortcomings. In response to these concerns, an FRD approach was used to improve the NORM management system. The logic was that the work was urgent and important, so needed concentrated and dedicated effort. It was a multi-stakeholder issue, so needed input from a range of angles, and in particular from operators who had not really been involved in the decision making in the previous “top down” process. However a number of issues had recently made us uncomfortable about our NORM management systems. These included 1 3 The team spent three days together off-site to build, exchange positions and analyse the job in hand. Team building exercises helped to build inter-personal understanding and trust. Rules of engagement were agreed. Brainstorming of the key NORM issues for each individual, and thus each sector, was carried out, and this was used to identify the perfect situation and the gaps to be filled. A complete general process map of NORM management from identification to disposal was developed, and possible improvement actions locked into each stage of the process map. These were then assessed, prioritised and locked into an improvement plan. An increasing number of incidents where NORM contaminated equipment has not been identified or has been wrongly assigned. The installation of a gate detector at our Torry base now identifies every mistake. Each of these incidents has potential legal exposure and reputational damage if the contaminated 163 IDENTIFICATION AND MARKING OF CONTAMINATED EQUIPMENT Each person on the team then worked their actions from the plan, meeting at monthly intervals to report progress and agree next steps as required. The Team Leader maintained rigorous control on progress. Process Map for each Installation with NORM Areas Highlighted Concrete Deliverables At the request of the FRD team, each installation developed a process plan, marked up with areas known to be NORM contaminated and a feel for the extent of the contamination. This will be used in work planning to predict NORM problems at the planning stage. The concrete deliverables developed by the FRD team fall into five groups • Working Procedures • Identification and Marking Contaminated Equipment • Record Keeping • Disposal • Information, Instruction and Training. of The Aberdeen University NORM Project Shell Expro has sponsored a project at Aberdeen University, part of which is to identify better meters for identification of NORM contamination. The researcher was part of the FRD team, which allowed better understanding of the operator requirements from such meters. It also allowed the FRD team to understand the restrictions and tradeoffs on such meters. WORKING PROCEDURES Analysis of the NORM Processes and Flow Diagrams The overall NORM process and each subprocess was mapped. Decision points were identified, and bottlenecks, duplications and unclear areas considered and resolved. The information flows supporting each process were also mapped and streamlined. This was used as the basis of Local Rules review. Use of EP15 Meter to Confirm External Tubular Contamination A particular problem addressed was the identification of external contamination on internally contaminated tubulars, where the internal NORM affects the external reading. A solution using an alpha sensing meter was developed. Improved Definitive Local Rules The Local Rules (radiation protection procedures) were reviewed by the team in a collaborative way. Two workshops were held with the Radiation Protection Supervisors from the offshore installations, at which further line by line reviews were carried out. This meant that all players had their concerns addressed, that good ideas from the users were incorporated, and that a much greater ownership and understanding of the procedures was obtained. Better SAP Descriptions of Meters The SAP ordering system was revised to give a better description of the NORM meters and thus make new meter ordering easier. Improved Meter Recalibration Process A pocket (A5) version was also produced for operator use on the plant. The meter repair and recalibration process was changed from each installation having its own meters and organising their own repair and calibration, to a pool of meters being held by Aberdeen University and receipt of a broken meter stimulating immediate return of a new meter. True NORM calibration standards will also be used. This will give better turnround times, better use of the meter pool and better calibration. Rationalisation of Permit Checklists and Local Rules Some contradictions between Permit to Work checklists and Local Rules were identified. A new system was set up where the Permit signposts directly to the Local Rules on radiation matters, rather than to checklists. 164 Improved Record Auditing Improved Standard Taping/Tagging/Labelling Conventions The annual Radiation Protection Adviser audit has been enlarged to include a detailed inspection of records. Marking of contaminated items was reviewed, and new improved tape, tags and labels designed. Green tape and labels for tested externally clean items were introduced. DISPOSAL Improved Information Flow and Transaction Efficiency between Shell and AEAT RECORD KEEPING The relationship and interface between Shell Expro and its onshore decontamination contractor, AEAT Dounreay, was discussed fully. Inefficiencies and “niggles” were identified and corrected, particularly around job accounting and information flow. Improved Source Register Layout The Source Register, which is the on-site record of audit and use of radioactive sources, was reviewed and improved in a collaborative way. Several new fields were introduced to allow better traceability across the total life of the source. Sponsor, Plan and Test Platform for NORM Reinjection Electronic Source Register Shell Expro considers reinjection as the best practicable environmental option for NORM disposal. Regulators are presently considering this option, and, if so minded, will permit it through review of Authorisations. The FRD team reviewed the technical and radiological protection issues around reinjection, and identified the Tern as first candidate platform. The FRD team has initiated work on an electronic source register to replace the paper version. This will give better access and search features. Improved LSA Work Record Form Consideration of New Decontamination Options The LSA Work Record Form, which is the overview of each NORM job, was reviewed and improved in the same way. A job numbering system was developed, and several new fields were introduced to give a complete record of the job. The FRD team investigated a series of ideas for more efficient decontamination of hardware, such as chemical dissolving (in situ or in baths), ultrasonic cleaning, and different types of jet hosing, such as in situ retrojetting. While these are all longer term projects, the team intends to keep a watching eye on them. New Sampling/Testing/Recording System for Offshore Discharges A better sampling, testing and recording system for offshore discharge data was developed and installed. New features include the use of Production Chemistry as coordinator, sample tracking through the intranet and result calculation and recording through a shared data system accessible directly from offshore. INFORMATION, INSTRUCTION AND TRAINING Policy on NORM versus LSA Naming Convention There are two distinct names in Shell Expro for the radioactive material produced with well fluids - Naturally Occurring Radioactive Material (NORM) and Low Specific Activity (LSA) scale. Both names have their strengths, but two names for the same thing can be confusing. The FRD team considered standardising on one name, but settled on a compromise position. New Recording System for Onshore NORM Arisings A shared data system capable of assigning Shell NORM arisings at AEAT Dounreay back to the source platform was developed and installed. This is also accessible directly from onshore. 165 FRD Brand Style (Logo, Look) NORM/LSA NEWSLETTERS The FRD team produced two NORM newsletters aimed at the general workforce. Feedback on these was good. The FRD team has developed its own brand style, with a definitive logo. The newsletter, overhead pack etc are in this style. This will give an identity to NORM informational material. SOFT DELIVERABLES Training Matrix In addition to these concrete deliverables, the use of the FRD process in this way sent several important messages around the organisation. The following were important. A matrix of NORM competence, on a scale 1 (aware) to 5 (expert) was produced. This shows the level of competence that each position with NORM responsibility requires. It also gives guidance on training methods to reach each competence level. Demonstration of Seriousness and Commitment to Solving NORM Problems New Training Package While the management has repeatedly emphasised the importance of proper NORM management, this amount of concentrated effort gives tangible evidence of that commitment. A new overhead training package was produced. This is a resource pack, allowing the presenter to select material from the pack appropriate to the knowledge and needs of the audience. It also includes a matrix which ties into the competence matrix above to guide the presenter on the material to use with each audience. Better Onshore/Offshore Liaison on NORM Issues - Openness and Trust The involvement of operations and decontamination contractor personnel in the decision making around NORM gave a better openness and trust across the onshore/offshore divide. By co-creating the solutions, a better understanding of where they came from and why they are the way they are, and thus a better ownership and buy-in, was obtained. Computer based training (CBT) for delivery of lower level training was investigated, but the FRD team felt that for such a complex and emotive subject, person to person training was best. Onshore Awareness and Training on NORM Emphasis on Onshore planning of NORM Work It was recognised at an early stage that planning of the NORM elements of work should start in the onshore planning of the job rather than when NORM is encountered offshore. This requires a greater awareness of NORM management among onshore supervisory, support and planning staff. A series of onshore workshops (about 2 hours) were run to raise onshore awareness. The Local Rules and onshore training now emphasise the need for NORM management to be built into workplans right at the onshore planning stage. Knowledge Improvement of FRD Team - Ambassadors Setup of RPS Network and RPS Workshops Participation in the FRD project created a group of eleven people with a much greater appreciation of NORM issues, who will act as advisers and ambassadors for the issue in their business sectors. The was a recognition that the Radiation Protection Supervisor (RPS) - the on-site supervisor responsible for NORM management at each location, is critical to the success of the system. An RPS network was established and two large one day RPS workshops run to get a common understanding and discussion of issues, and particularly a detailed review of the Local Rules. Focusing and Communicating the Range of NORM Work Ongoing The FRD team found that a number of small projects and initiatives on NORM improvement were going on in isolation. Also a lot of good ideas had been implemented on 166 specific locations. The FRD team focussed, collated and communicated these. business. This would not have been achieved by conventional review systems. Understanding of Pros and Cons of Offshore versus Onshore Decontamination Team and Authors Paul Abernethy Decontamination Contractor Representative Fred Beadling Operations Jim Beresford-Lambert Procurement Adviser Douglas Clark Corporate HS&E Adviser Contact Author Muriel Dorthe Research Student Erica Edwards Logistics Adviser Terry Harvey Operations Brian Heaton Radiation Protection Adviser Brian McKendrick Operations Leader Ian Reynolds Northern Business Unit HS&E Adviser Stuart McGregor Production Chemist There has been a growing demand for offshore NORM decontamination. The FRD team, during the mapping phase, reviewed when offshore decontamination is appropriate, under what circumstances, and what arrangements must be put in place. This has been formalised into the Local Rules. Contact with SEPA SEPA is the regulator of NORM disposal. They were kept appraised of the work being done by the FRD team, and invited to present their position at the RPS workshops. This allowed us to give SEPA a favourable impression of our commitment to improvement of our NORM management, and allowed us a better understanding of the drivers on them as regulator. Dave Windle TENC Asset Sponsor Manager QUESTIONS AND ANSWERS SESSION Question - Ed Brookes, BROA Could I kick off Brian. That’s a very interesting video. Is that just for Shell or are you going to be making a profit and selling it? Contact with AEAT AEAT is Shell Expro’s onshore decontamination contractor. They were invited to present details of their business at the RPS workshops. This gave a better understanding of what they do. Answer – Mr Brian McKendrick, Shell Expro Let’s face it, with health and safety and environmental matters in Shell Expro we don’t make profits! But we’re happy to share our experiences with other operators. Ideas Exchange with BP Question - Dr Ahsan Saleem, HSE I was interested in the training matrix, where you had level 1 to 5, and particularly with the fact that you said there is some offshore decontamination work that goes on. Do you have any classified workers and how do you monitor their doses? BP has been appraised of the work of the FRD project, and is impressed with what has been done. Joint opportunities have been identified. Setup of Radiation Coordination Group FRD teams, by definition, do the work required, then disband. It was felt that, to embed the lessons of the FRD project and to maintain the new systems, a Radiation Coordination Group be set up to maintain the momentum. The membership will be the same as the FRD team, and a Terms of Reference has been drawn up. Answer – Mr Brian McKendrick, Shell Expro Basically our classified workers are from our ISE contractor, Rigblast, and they are classified workers and they do have certification for offshore decontamination. Question - Alan Wilson, PGS Not just the video for across industry training but it looks as though the entire job has been well thought out and I’m also impressed. With the rest of the training, is that possible for something like a cross industry initiative? Conclusion The use of an FRD approach has resulted in a much more robust NORM management system, with the requirements of all stakeholders recognised and accommodated, and understanding and buy-in from around the Answer – Mr Brian McKendrick, Shell Expro 167 The actual training consists of, from level 1 to level 5, about 65 viewgraphs. Obviously for level 1 only about 10 or so viewgraphs will be used and then up to level 5 (the expert level), the 65. I’m sure that they can also be made available. Is that okay Stuart? Answer - Brian McKendrick, Shell Expro I’m actually sure we do. People in the Shell Expro safety department, have you got any history of this? [to colleagues in audience – no immediate response] For instance, with the environment, we had to go back to flared gas on one platform. It was so huge we knew there was a problem but the difficulty was again there were quite a few potential solutions. We have a big FRD team at the moment looking at that as well, but it’s not a very good reputational thing for our platforms. Answer – Mr Stuart Whitely, Shell Expro Yes, Brian. The main forum for sharing knowledge that we’ve got at the moment is a UKOOA Radiation Working Group which sits under the Environmental Committee. I think in time it will be forming links with BROA and IADC and people like that, again to share the knowledge as wide as possible. Comment – Mr Lindsay Ross, BP For a similar size organisation (BP) it seems like a good way of approaching these type of issues. Question – Mr Lindsay Ross, BP I just wonder if you use this FRD focused results delivery nutcracker that you have here to tackle any other kind of occupational health hygiene-related issues? 168 TACKLING BAD VIBES IN THE OIL AND GAS INDUSTRY – A CASE STUDY ON HAND ARM VIBRATION SYNDROME (HAVS) Mr Stuart McIlroy, Senior HSE Advisor, Halliburton Brown and Root Introduction followed by pain and loss of grip during manual tasks. HAVS is a prescribed industrial disease and is reportable under the Reporting of injuries, diseases and dangerous occurrence regulations (RIDDOR). According to HSE funded research more than a million workers are exposed to potentially harmful levels of vibration. Around 300,000 have symptoms of vibration white finger. The proposals for a Directive on vibration are progressing through the E.U System and are likely to effect all activities that cause hand arm vibration. If as seems likely the directive is adopted this will lead to the introduction of exposure limit values and with it a change in U.K law, this in turn will have a significant impact on how organisations manage the risks associated with Physical agents such as vibration. It can be seen as a ‘people problem’ – it hurts people in the workplace and continued exposure to high levels of vibration can make the health effects irreversible. The results of this type of exposure are graphically shown in the HSE health promotion video “Hard to Handle” The Case Study The case study looks at vibration issues identified during work carried out by members of the integrated HSE team on Shell Central Business unit. The focus is on the way in which information and ideas were shared with others within the industry and how that communication process ensured that the tools were available for effective management of the issue within the Oil and Gas Industry. It would be reasonable to say that If employers are to work within the law they have to ensure they have effective means of controlling the risk associated with using hand held power tools. This was highlighted in the1996 test case when a group of miners took out a civil action against their employer and successfully won their case. The employer - British Coal were well aware of the dangers of using percussion tools as far back as 1973, they had carried out a study, the results of which were largely suppressed or ignored. The judge ruled that they should have taken steps to prevent injury by warning those working with percussion tools of the possible dangers. At the start of 1998 there was a nervousness surrounding the possibility that the Physical agents directive would be introduced – this was the directive aimed at controlling vibration exposure to individuals who regularly used percussion/power tools. The HSE were raising the awareness of the HAVS problem and were also taking a keen interest in how companies were managing the issue – from a business unit perspective we were conscious that existing controls for managing vibration exposure was based on custom and practice rather than scientific measurement. Workers whose hands are regularly exposed to high vibration may suffer from several kinds of injury to the hands and arms - collectively known as Hand Arm Vibration Syndrome (HAVS) common names for such injuries are • Dead Finger • Dead Hand • White finger In conjunction with the Tool Manufacturers and fabric maintenance contractors a power tool trial was set up the main deliverables being to:- The injuries may be due to impaired blood circulation, neurological and muscular damage or damage to joints. • Measuring the vibration exposure levels generated by using hand held power tools Damage is progressive and may not be apparent initially; gradual numbness and paleness increase with cold conditions 169 • Introduction of engineering controls such as ultra high pressure water jetting as a method of removing weld metal around a scrap compressor housing. Conventional removal would mean hours of exposure using a caulking gun • Benchmarking against current exposure standards • Identify areas of weakness in achieving compliance with future legislation Occupational hygienists were contracted in to take measurements to a recognised industry standard; all power tools were tested under normal operating conditions. By being pro active in addressing the issue this provided a good opportunity to apply best practice within the business unit. Such controls were identified and implemented as part of the activity risk assessment process, care being taken not to eliminate one problem and introduce another! A consensus was reached that a co-operative approach was the way forward to facilitate understanding and common ground to managing the issues. During the course of 1998 the team gathered information internal and external to the industry on how best to tackle the issues – Shell occupational health department introduced Design Engineers from Atlas Copco who manufactured low vibration tooling. – They had vast experience in designing high performance tooling for industry and had worked extensively in this area with British Aerospace. British aerospace were happy to share their experiences with us and this gave us some direction on how to formulate a workable policy for controlling HAVS, There was recognition that HAVS was a live issue and not all companies would face the same problems in addressing the issue. One example being the Fabrication Facility where due to the nature of the business workforce exposure to vibration may be high. Compare this against a small offshore installation where the use of power tools is infrequent – in both cases there would be a need to balance the cost of proposed controls against the perceived risk of exposure. This led to the introduction of a Business unit HAV policy developed as an operational guide to managers and supervisors to assist them in applying appropriate controls for the health and safety of exposed employees. The key elements of the policy were as follows Lack of available HSE resource would also present problems to small service companies – how many could call on a resident Occupational health expert to give them sound advice, the more likely scenario being one of taking HSE advice from ‘another hat’ • To provide management awareness of where there might be a risk of HAVS and the type of control measures to reduce exposure • To enable those employees likely to be exposed to recognise and understand the nature of the problem and the precautions to be observed • To ensure the above employees recognise early onset of symptoms and how to obtain expert advice. HSE specialist inspectors attended these meetings, they acknowledged that the group was moving along the right lines in terms of identifying where likely exposure would arise. The question was raised as to who ‘owned ‘the problem was it the oil companies or the contracting companies themselves Although operating companies have responsibility to satisfy themselves that activities are being carried out on their installations and Facilities in a safe manner ultimately it’s the contracting companies responsibility for managing the risk and for the health of their employees in the workplace. During the first quarter of 1999 a series of meetings were held involving Atlas Copco as well as operating and service companies from the industry. Given that ownership of the problem lay with the contracting companies it was decided that the best way to raise the profile would be through the Offshore Contractors Association. It was clear from the large number of attendees at these meetings that many companies had been working in isolation on the issue, many companies were already implementing workable solutions to reduce vibration exposure for example: - A case was put before the OCA Technical committee who noted that although there was some excellent guidance already published 170 • Agreed common approach for managing the issue • Tangible benefits to the workforce including the HSE publication Vibration Solutions it was agreed that there was a need for some specific industry guidance consequently a working group was set up with a remit to: - Practice Sharing Opportunities With the imminent introduction of the Physical Agents Directive comes new challenges, daily exposure action values and daily exposure limit values will be introduced to protect personnel exposed to vibration on a regular basis. The Directive will have an impact on measurement methodology and with it a need to develop standard methodology for taking of measurements. The OCA document entitled Guidance notes of Good Contracting Practice within the Oil and Gas Industry –Hand Arm Vibration Syndrome was published in January 2000. The OCA Health Committee met in November 2000 to follow up on identified issues and will continue to work towards industry wide standards for management of HAVS. Prior to issue of the document practice sharing had been carried out in an ad hoc manner – within my own organisation this was achieved by carrying out presentations at safety meetings and forums and through articles published in company bulletins Conclusions • Develop a guidance document that would benefit and recognise the broad needs of the oil and gas industry i.e. fabrication facility V small manned platform, occupational hygienist V “another hat”. One of the key areas in achieving a “step Change” is the sharing of HS&E information and best practice to satisfy project needs and guide industry in general. The approach to practice sharing initially was adhoc, however safety professionals played a large part in driving the issue and developing industry guidance on the subject. After publication of the OCA guidance we were able to promote the document in a more formal manner. Forums such as the Industry led Step Change in safety presented an opportunity to promote the work carried out to date -the shopping Mall workshops were specifically set up to enable anyone to cherry pick good ideas and best practice for use within their own organisation. Practice sharing provided some practical examples of elimination and reduction measurers, this showed excellent lateral thinking when looking for solutions to reduce HAVS exposure in the workplace, these examples were drawn from all areas of our industry. To date a total of 200 copies of the document have been taken up by member companies of the OCA and operating companies of UKOOA. Due to the different working environments within the industry there will be a need for individual companies to take a risk based approach when adopting management controls to meet their given situation. An OCA data bank was set up to encourage further sharing of knowledge and experiences on the subject, reference and how to access the OCA data bank are made in the document. The OCA working group acknowledged this as a further opportunity to cascade and share knowledge and experience – so far there has been poor response to this offer As a direct result of trading ideas many companies have now introduced tangible benefits to the workforce – brought about by introducing improved tooling and understanding of the problem. This in itself can be seen as a motivator for improved HSE performance amongst the workforce. In November 2000 the case study was used as an example of how the practice sharing process presently works in the Oil and Gas Industry, there were seen to be many plus points including: - Overall we set out to benchmark against future legislation and I think that from the efforts to date the different sectors of our industry can draw on the lessons learnt along the way and are in a position to comply with future legislation • Exchange of information and vibration case studies within the industry • Buying in of experience external to our Industry – British Aerospace study 171 172 REPORT ON HAND ARM VIBRATION SYNDROME Ian Campbell, BP, HSE Advisor Health A major focus for the HSE this year is in the area of occupational health. Noise and other allied health issues has been, and will continue to be scrutinised by the HSE Inspectors looking at how individual assets comply with legislation, regulations and guidance. The Harding platform has a HAVS working practice document, first issued in May 1999. Since then the document has been updated twice to incorporate comments as a result of two external audits. Specification:- Responsible person: Platform OIM/OOE Ensuring that the power tools used on Harding create the lowest HAVS risk whilst being suitable for the intended workscope • Both BP Amoco and contractor-owned tools used on the platform shall be specified as having the lowest HAVS risk but still be able to be used for a practicable working period • All Harding contracts will include the Harding Tool Specification as a contract requirement, and that data sheets are provided for all equipment. BP Amoco Harding has a recognised duty of care to ensure that the local workforce are protected against the effects of Hand-Arm Vibration Syndrome (HAVS), under the following legislation; Registration:- Responsible person: Platform HSEA [ HEALTH ] Ensuring that all HAVS risk equipment is uniquely registered on a central platform register that records all tool details including HAVS risk level All powered tools on Harding will:• be registered in an index bearing unique identification numbers and HAVS details as provided by the supplier / manufacturer • be issued with a HAVS Risk Assessment Sheet recording vibration level and recommended daily use • be supplied with a coloured label showing the maximum permissible use per day • Section 2 of the Health and Safety at Work Act 1974 • Management of Health and Safety at Work Regulations 1992 • Supply of Machinery ( Safety) Regulation 1992 • The Provision and Use of Work Equipment Regulations 1992 (PUWER) • Reporting of Injuries, Disease and Dangerous Occurrences Regulation 1995 (RIDDOR) • HSE Guidance on Hand -Arm Vibration HS (G) 88. Current legislation in the UK, recommends health surveillance for workers who’s exposure regularly exceeds a guidance level for maximum hand - arm vibration exposure of 2.8 ms² over 8 hours. Awareness:- Responsible person: HSEA [ HEALTH ] Ensuring that all Harding personnel are aware of hand arm vibration syndrome and the control measures to be taken to reduce risk • All new personnel to the Harding platform will be made aware of the Harding HAVS policy • All personnel using powered tools and will be trained in the requirements of the Harding HAVS Policy before being issued with the tools. This will include watching the HAVS video / Interactive CD - ROM Harding prior to May 1999, had made attempts to control HAVS exposure to personnel by the issue of HAVS timesheets whenever a vibrating tool was in use. However this was not uniformly used across the platform, nor was the actual level of vibration generated from a tool known. The HAVS working practice document sets out the standard by which all tools sent to the Harding platform and tools already on the platform are controlled. Risk Assessment:- Responsible person: HSEA [ HEALTH ] Ensuring that the HAVS risk is assessed and minimised • Where possible, alternative methods shall be used to remove the risk of hand arm vibration syndrome The principle methods of control are Registration, Specification, Risk Assessment, Reporting, Awareness and Analysis & Audit, for example; 173 • Risk Assessments will be carried out to identify the minimisation of HAVS exposure prior to each task frequencies between 5 and 20 Hz and less outside these frequencies. Two methods of measuring vibration are widely used. Tri - axial accelerometer measures and sums the three directions x, y and z simultaneously, however, measuring separately in each direction x, y and z gives additional information on the direction with the highest vibration, the individual results are then summed to give a total vibration level. It is widely accepted that measuring individually in the three directions gives the most accurate vibration level. Reporting:- Responsible person: HSEA [ HEALTH ] Ensuring that all platform personnel record their use of power tools in a controllable and auditable manner • Each registered HAVS tool user on Harding will be issued with a HAVS Log Sheet • HAVS tool users will be responsible for completing HAVS Log Sheets with actual exposure time • Supervisors and users will ensure that both the maximum permitted time and the daily cumulative time for the tool(s) is not exceeded The HSE recommends a programme of preventative measures and health surveillance where workers exposure regularly exceeds 2.8ms² for a period of 8hours, which is achieved using the following mathematical calculation A(8) =ah.w.x√(t/8). The value A(8) is equivalent to an average vibration level of 2.8ms² for a period of 8hours. This gives the following exposure / level relationship; Analysis & Audit:- Responsible person: HSEA [ HEALTH ] The Harding HAVS Policy will use a process of data analysis and audit to drive a continuous HAVS risk improvement process. Exposure time ( hours ) 16 4 2 1 Vibration ah.w ms² 2.8 4 5.68 11.2 The initial approach utilised on the Harding Platform, was to register the tools with a unique HAVS number, then to request the companies who supplied the tools ( Deutag, Cape, KOGL and AMEC ) for the tool product data sheet. 8 ½ 2 Thus a tool that vibrates at 11.2 ms² can only safely be used for 30 minutes, however a tools that vibrates at 2ms² can safely be used for up to 16 hours. Tool product sheets usually accompany a tool which is purchased from a DIY outlet etc, however it was not usual practice for the complete data sheet to travel offshore. Normally electrical and air tools arrived offshore with a letter of conformity issued by the contracting company, which cover topics as; Safety and Operating Instructions, Use of the Machine, Maintenance and Repair, Lubrication, Air Supply, Electrical supply etc., but rarely included information on Vibration or noise generated by the tool. Thus it has been a major achievement that information for every tool has eventually been received on the platform, with details of Vibration and noise. This contained the vital information that allowed the risk assessment process to begin. One of the key components to the Harding HAVS practice was the label to be attached to the Hand tools. Most tools already have some distinguishing mark or test certificate attached, Harding wanted a system that was easily identifiable to all workers, thus Harding opted for a visual risk system, utilising the concept of the traffic lights ; ( See appendix 1 ) • Red : Potentially Hazardous, can be used up to 2 hours • Yellow : Medium risk, can be used for between 2 - 4 hours • Green : Slight risk, can be used between 4 - 8 hours • Black : Low risk, can be used between 8 - 12 hours Hand-arm vibration is measured in terms of acceleration (in ms²). Therefore measurements are made with an accelerometer attached to either the tool or the workpiece. However, because the risk depends on the frequency content of the vibration, the signal from the accelerometer is passed through an electrical filter. This filter gives greater weighting to The system above was well received by the workforce, it allowed them to easily identify and differentiate between high risk and low risk tools and offered a degree of empowerment to the workforce in choosing the tool for the task. With the arrival of the tool data sheets, all tools were risked assessed and 174 labelled according to the above classification, (see appendix 2) and a tool register established, ( see appendix 3 ). All risk assessment sheets on the installation had been formed on the information supplied, which we now know to be inaccurate at the time of testing. Thus personnel were exposed to vibration levels higher than those recommended by the HSE. There are various tools which are known to cause high vibration in particular, Needle guns, impact wrenches and air saws. Therefore within the Harding working practice we specified that power tools should create the lowest HAVS risk commensurate with being suitable for the task proposed. All companies supplying personnel and power tools were further advised that the platform expected high vibration red labelled tools to be gradually phased out and replaced with HAVS friendly tools. Through continuous onboard audits the main contracting companies have been challenged, and responded positively in replacing high vibration tools with tools that they believed to be low vibration. The large disparity between the measured vibration levels and data supplied with the tools may be due to several factors, including wear of the tool during normal use, the condition of the blade or disc fitted to the tool and the test conditions. It is not known the exact methods that tool manufactures use to obtain their vibration and noise levels. The vast majority of tools used and tested during this audit on BP Harding were under one year old. Through discussions with various BPA sites there appears to be a requirement for coaching of the workforce into the mechanics of Hand Arm Vibration syndrome and the provisions to mitigate against its effects, in the majority of BPA sites in the UK. During May 2000, the Harding platform was audited, by an Engineer from Acoustic Technology Limited ( ATL ). Part of the ATL audit was to conduct the final Noise survey on the ‘Green Compressor’, but the visit was mainly to obtain vibration data readings from all the hand - held vibrating tools in operation on the Harding Platform and compare them with previously obtained data. The Engineer used a Bruel and Kjaer Type 2537 Hand Arm Vibration Kit, fitted with a Bruel and Klaer Type 4505 accelerometer. This equipment was calibrated prior to and after the measurement using a Bruel and Kjaer Type 4294 Vibration Exciter. ATL’s calibration procedures are traceable to NPL standards. Recommendations There are several measures which can be implement which will reduce the potential effect of vibration to the hand, these include • • • • • • • • • • For each type of tool the hand - arm vibration measurements were taken over a representative period, by an operator carrying out a simulated task. The measurement period included variations in vibration levels due to pressure, lifting or movement of the tool. The meter averaged the vibration level over the measured period. Measurements were made using the integral hand - arm weighting filter built into this unit. All measurements were in terms of average hand - arm weighted acceleration (ah.w ms²). All results obtained were then entered into a data base and are presented in ( appendix 4 ). Factors influencing grip Posture Tool Choice Vibration Isolation Work Rotation and Planning Tool Maintenance Training and Information Health Surveillance Purchasing Policy Contracts There will be continuous maintenance and construction activities both offshore and onshore within BPA. It is recommended that each unit should address the Hand - Arm vibration issue., by the implementation of recognised tools and best practice. The HSE recently conducted an audit of the management of HAVS on Harding and regard the Harding model as best practice. Conclusion It is clear that there is a significant level of disparity between the information supplied with the tools and the actual results obtained by the ATL Engineer whilst testing on the installation, (appendix 3 & 4 ).

QUESTIONS AND ANSWERS SESSION Question - Dave Freeman, HSE Norwich The rest period, you say for using the tools ‘per day’. Is that a per 12 hour day or 24 hour day and are rest periods between a week or a fortnight? Do you have weekends off? Are the rest periods critical to your findings please? Comment – Dr Jim Keech, BP, Chairman of UKOOA HAC I must sound a warning bell for any process that would be so grossly discriminating as was maybe suggested from the back of the room here. We have to be very careful as an industry. We have a reputation of being somewhat elitist in terms of selecting our workers. It is quite contrary to the Disability Discrimination Act. As the chair of the UKOOA Health Advisory Committee I am very sensitive about this and although it is a sensible precaution to exclude those who already may have suffered some harm, I think we must be very careful not to use that as a selection procedure. I would recommend the preventative measures which we’ve heard from the speakers as against selection. Answer – Richard McLellan, BP I think the HSE guidance says that you can have an exposure of 2.8 metres per second for every 24 hour period. The long term is that if someone is exposed to 2.8 metres per second on a five day week over 8 years, 15% of them will suffer white finger or something like that. I’m getting nodding heads from the HSE, so I think that’s pretty near right. Question - Tony Parkinson, Noble Drilling, for Texaco Did you do calculations on the eight hour day or was it 12 hours for offshore workers? Answer – Richard McLellan, BP We do it on eight hours, which is another factor of safety. Comment - Mr Graham Cowling, Acoustic Technology Ltd Just to clarify one thing. Probably one of the reasons why you are getting unsatisfactory data from manufacturers is not because they’re trying to sell you tools but the actual standards that the tools are measured to, have them hanging on wires unloaded. Whereas the measurements you take have the tools in the real situation with people actually using them up against the wall. So there’s likely to be quite a difference. It is the fault of the standards. This can be easily remedied. You credited Amec with giving you good data and that’s because they have bothered to set up a testing booth. Also they train the people who pack up the tools in boxes and send them to you, to a basic level in competence in measuring. That’s something that can be easily achieved by contractors. Question - Steve Taylor, Shell Expro Southern North Sea Again a question for the vibration boys on their experience. We’ve looked at all the good stuff for reducing the risk as such. Have we looked at the susceptibility of certain people to this? That is, through pre-employment medicals or for on-going reasons, are there certain people who just shouldn’t be doing it in the first place? Answer - Richard McLellan, BP The guys get an induction. They’re registered in the system before they go on. There’s a questionnaire we go through, we show them the video, discuss the system, how it works. I can’t say we’ve ever identified anyone with a problem yet, but we would refer that onshore to our medical department. If we had a guy who looked as though he was at risk due to previous exposure, or if he had blanching or tingling, we’d refer him onshore to our medical department for referral for further advice. Answer – Ian Campbell? Thanks for that Graham. We are aware also that the HSE are setting up a working group looking at the measurements so that we get effective and cross industry measurements in relation to power tools. Question - Tony Garner, Conoco Do you take into account any off-the-job exposures? Answer – Ian Campbell? That is part of our induction process, actually asking the guys if they have experience of it or 183 Answer – unknown speaker No. Comment – Edmund Brookes, BROA I suppose that argument could well be applied equally with sound with a chap being at a disco all night. He then goes offshore and he’s got his ears ringing because of the noise level. We’ve got no control over that. That raises all sorts of issues. 184 DAY 3 MORNING SESSION SESSION THEME – HUMAN FACTORS AND PSYCHOLOGICAL HEALTH 185 186 CIRCADIAN ADAPTATION TO SHIFT CHANGE IN OFFSHORE SHIFT WORKERS Michelle Gibbs, S. Hampton, L. Morgan and Professor Josephine Arendt, Centre for Chronobiology, University of Surrey discussed as a probable factor in decreased work efficiency and vulnerability to human error during night work (Costa, 1997). Abstract There is increasing interest in the health problems associated with working shifts and the role of circadian adaptation to a night shift. Previously it has been shown that physiological adaptation to night shift can be achieved in offshore shift workers, but that shift schedule and season may both be important influencing factors. In this study 11 males were studied for a fourteen-day tour offshore on a schedule of 7 nights followed by 7 days. Circadian adaptation was measured by acrophase of the urinary melatonin metabolite 6-sulphatoxymelatonin (aMT6s). A significant difference was found in the mean acrophase (peak time) of aMT6s between the start (05:34h) and end (10.95h) of the night shift week (p = 0.0004). There was no significant difference in the mean acrophase between the start (11:04h) and end (12:59h) of the day shift week, suggesting that as a group the subjects did adapt to the night shift, but did not adapt to the change back to day shift. However the inter-subject variation was high and increased over the day shift week. Adaptation to a night shift occurred in 73% (n = 8) of subjects, of those who adapt to nights, only 37.5% (n = 3) adapted back to day shift. A further 37.5% showed no adaptation to night or day shift. All the adaptation to the night shift occurred by delay, but the adaptation to day shift showed both advance (n=1) and delay (n=2) of the internal clock. These individual differences clearly require further study. Working shifts, especially night shift, causes the body to attempt to make physiological adjustments in order to adapt to the different working times. These physiological adjustments require investigation, not only to identify changes that may have health and safety implications, but also to distinguish if certain shift patterns offer greater or lesser risk than others, and to find solutions. Shift schedules Offshore oil and gas installation workers have different shift patterns and environmental factors to onshore shiftworkers, producing different physiological responses particularly with regard to circadian adaptation to night shifts. There is currently a number of shift patterns being worked offshore and it is unclear if there are benefits or increased problems with each schedule. The complexity of designing shift schedules requires consideration of factors other than simply the most appropriate for circadian adaptation. Operational constraints, such as helicopter schedules and crew change arrangements, further complicate decisions about shift rotation schedules. Adaptation to shift work offshore The offshore petrochemical industry is the only industry working 12-hour shifts for 7,14 or 21 days/nights with managed meal times, segregated shifts and daytime darkness for night workers. While it has been shown that, in some schedules they do physiologically adapt to a night shift (Barnes et al, 1998a), the process takes days, so they may be working a significant percentage of their tour in an unadapted state on both the day and night shifts. Barnes showed that on North Sea rigs, for a 14-day 12-hour night shift (1800-0600h), subjects are out of phase for at least the first 45 days of the night shift (Barnes et al, 1998a). For a 7 day sequence starting with day shift (1200-2400h) then switching to night shift (2400-1200h) the majority of crew do not Introduction Shift work is becoming more and more a necessary part of working life as the demand for a 24 hour society increases, yet it introduces some concerns for the health & safety of the worker. Reported symptoms of reduced well being amongst shift workers include fatigue, and reduced sleep quality (Nicholson and D’Auria, 1999). In addition to these undesired symptoms, when the working environment incorporates dangerous activity fatigue and reduced cognitive performance present a more immediate health and safety risk. Performance and safety are of concern in shift workers and circadian rhythms have been 187 pattern amongst them. The subjects have therefore been grouped into those who did not adapt at all (n = 3) figure 2, those who adapted to the night shift but not to the day shift (n = 5) figure 3, and those who adapted to both the night and day shifts (n = 3) figure 4. Of the subjects who adapted to both of the shift changes, all demonstrated adaptation to the night shift by delay of their rhythm but further adaptation to the day shift was by a combination of delay and advance (figure 4). adapt to night shift (Barnes et al, 1998b). It is likely that for a 7 day sequence, 12 hour shift, starting with night shift (1800-0600h), subjects will be out of phase for at least 4-5 days out of 7 days on night shift followed by 4-5 days out of phase on day shift. Here we have studied the schedule that causes the worker to attempt adaptation to two shift changes over a two-week period, working seven nights followed by seven days. The objective was to measure the extent and direction of circadian adaptation in a 14 day schedule of 7 nights and 7 days (12 hour shifts 1800h to 0600h) on oil installations in the North Sea (61oN). Discussion We conclude that on a 14 day schedule of 7 nights (1800h to 0600h) followed by 7 days (0600h to 1800h) adaptation to a night shift did occur in 73% (n = 8) of subjects but with high inter-subject variation of adaptation rate and extent. Of those who adapted to nights 37.5% (n = 3) adapt to the change back to day shift. All adaptation to the night shift on this schedule occurs by delay, but the adaptation to day shift is divided in the ratio 2:1. Methods Eleven healthy male subjects aged between 25 and 47 years with a mean body mass index of 25.7kg/m2 (± 2.45 SD), were studied for a fourteen day tour offshore. Circadian adaptation was measured by the urinary melatonin metabolite 6-sulphatoxymelatonin (aMT6s). Sequential 3-4h urine collections (810h overnight) were taken throughout the 14day study and aliquots frozen for analysis of the urinary melatonin metabolite aMT6s, by specific radioimmunoassay (Aldhous and Arendt, 1988). Acrophase of the aMT6s rhythm was calculated by cosinor analysis. The criteria for adaptation was taken as at least a three hour acrophase shift from baseline maintained for three or more days, and for adaptation back to day shift was a shift in acrophase to within 3 hours of the basal acrophase time. Day two was used as basal acrophase, as this was the first full 24-hour period of the study. Paired t-tests were applied to the data to identify statistically significant data. Previously circadian adaptation in offshore shiftworkers has been found in a schedule of 14 nights 1800h to 0600h by delay of the circadian rhythm, and in a schedule of 7 days and 7 nights working 00.00h to 12.00h during (Barnes et al, 1998b), where the partial adaptation was by advance of the rhythm. This difference indicates that the work time within the schedule may be critical in the direction of adaptation. Here, in contrast, we have found a combination of advance and delay, along with no adaptation at all within the same schedule. The schedule of 7 nights followed by 7 days is the most complex in terms of adaptation, requiring an adjustment twice during the schedule. The subjects while all working on the same installation had differing duties and therefore different activity and environmental conditions such as light exposure. There may be endogenous differences as well as these exogenous influences contributing to the individual variation in adaptation found here. Results There was a significant difference in the mean acrophase between the start (05:34h) and end (10.95h) of the night shift week (p = 0.0004) suggesting that as a group the subjects did adapt to the night shift (figure 1.). There was no significant difference in the acrophase change between the start (11:04h) and end (12:59h) of the day shift week suggesting that as a group the subjects did not adapt to the change back to day shift. Subject specific light exposure data may provide some explanation of the variation in adaptation patterns as the duration, timing and brightness of light exposure are associated with the entrainment of circadian rhythms. Light exposure data has been collected subjects on a shift schedule of 14 nights and will be recorded on the 7N/7D shift schedule in further studies to determine the most desirable for performance and health, along side the patterns and physiological effects of adaptation. If adaptation is found to be The variance between the subjects was high and increased over the day shift week, representing the subjects as a group serves only to disguise the variation in adaptation 188 desirable, then studies applying strategies for encouraging adaptation will also be proposed. on offshore oil installations during a 2 week 12-h night shift.

I don’t really think we know enough about the medium-term effects, let alone the long-term effects. Clearly as Jo said, one of the ways of extending this is to focus not just on what’s going on on the installations. I’d like to see it extended over a much longer time period, to really assess the impact of leave and work in combination. I think this is a weakness of shiftwork research in general, not just the studies that we’re doing offshore. Question - Melanie Clark, Amey Vectra Are you intending or hoping to use those Acti wrist watches which we’ve used, I’ve certainly used in the past, to get them to observe the effect when they go home? So, not just when they’re on the rig or platform but when they’re at home as well? Answer – Professor Josephine Arendt, University of Surrey Yes absolutely. Question - Gareth Powell, BP Did you notice any difference at all in the results from installations at different latitudes? I notice you had the latitudes on some of them and some of them are quite far north. I wonder if you’ve got any of the southern sector ones and was there any difference there? Question - Tony Garner, Conoco Have you done any crossover trials from the 7/7 and 14/14 people and seen if the response is the same? Answer – Professor Josephine Arendt, University of Surrey You mean, have we done 14 days day shift as well as 14 days night shift? Answer – Professor Josephine Arendt, University of Surrey That was why it was interesting to do fourteen nights at 53°N and fourteen nights at 61°N, because the daylight changes are very much greater at 61°N. In the winter there is much less likelihood of exposure to natural light at 61°N than there is at 53°N. Natural light at the wrong time will counter adaptation to night shift. This is if you like a classical situation. You come off night shift at 6 o’clock in the morning onshore and you go home in light frequently and that light is at exactly the wrong time if you wanted to adapt. It counters the shift of your clock, that morning light. We actually believe that the different results we get from the drilling rig, for example, the 7 days/7 nights compared to the 14 nights, is related to the light exposure that these guys have because of the different hours of work that they did. This is why we are currently recording light exposure. But in fact, when we looked at 53°N and at 61°N on the 14 nights, they all adapted on both of those latitudes so that’s comforting from the point of view of people who favour 14 nights on the trot. Question - Tony Garner, Conoco Yes, do they respond in the same way? Answer – Professor Josephine Arendt, University of Surrey These are people who alternate on the Tern study that we did. They did 2 weeks of nights, 2 weeks off and then 2 weeks of days, so we have the day shift to compare with the night shift. Question - Tony Garner, Conoco Sorry, I was meaning have they done a 7 day day shift, then a night shift and then maybe a 14 day day shift? Answer – Professor Josephine Arendt, University of Surrey No we haven’t got that comparative data. That would be very interesting. Question - Jake Molloy, OILC Offshore Union Theoretically, I suppose hypothetically, do you believe, or do you consider, that a reduction in shift work, that is to say extended leave periods, may reduce the health risks to workers carrying out these sorts of shift patterns? Question - Alan Atkinson, Total Fina Elf, Norway Did you take into consideration the ages of the participants? It’s just that during unscientific discussions with our own people, when they hit the 45-50 bracket they have a tremendous problem with shift work and coming back onto normal living when they go home. Answer – Professor Josephine Arendt, University of Surrey Well quite honestly I think that question is enormously important, but it’s beyond my expertise. I don’t know whether Andy Smith would like to reply? 192 Question - Rab Wilson, AEEU Could I just attach to that question there. What percentage of male and female were in the study as well? Answer – Professor Josephine Arendt, University of Surrey We have a trend which is not significant yet to an increase of triacylglycerol during the night shift but it is not significant yet. Answer – Professor Josephine Arendt, University of Surrey I regret to say they were all male. We’d love to have a mix of course and look at them separately. This intolerance is a well-known phenomenon as you get older. It’s also true of adapting to time zone change. It becomes much harder as you get older. We have a range of ages. I think the average age is about 40. We’re grateful for anybody who volunteers so we’re not going turn anybody down on the grounds of age but we haven’t got enough to look at age differences. Question - Ian Campbell, BP Amoco May it possibly be due to the fact that for the night shift workers, the only meal they have available prior going to bed is a nice big fatty breakfast? Answer – Professor Josephine Arendt, University of Surrey This is where I think I ought to introduce Michelle because Michelle has expertise in the dietary area. We do get significant increases in triacylglycerol in simulation experiments that we do in the lab very clearly, no doubt about it, and incidentally evidence that light treatment reduces that blood lipid. I think the reason we’re not getting significance is because the diet is uncontrolled out there as you quite rightly point out. This is going to make a huge difference to the results. We are keeping nutrition diaries so that we can look back at what they’ve eaten but frankly I don’t think they’re terribly reliable. Question - Tony Parkinson, Noble Drilling, for Texaco Our platform does 2 weeks off, 2 weeks on. Have you thought about the rigs that do 3/3? Answer – Professor Josephine University of Surrey We’d like to get at them. Please. Arendt, Question - Ian Campbell, BP Amoco You mentioned at the start there that one of the things you were looking at were the markers for CHD. Have you got any information on results so far? 193 194 MANAGING STRESS IN THE OFFSHORE WORKING ENVIRONMENT Dr Valerie J Sutherland, Chartered Psychologist, SutherlandBradley Associates The topic of stress has featured on offshore oil and gas industry agendas for nearly two decades. However, as an academic and consultant, observing from the outside, I believe that unease about ‘stress’ and stress management still exists in the Industry. Some forward thinking companies have gained benefits from including stress management in their business plan. However, others have simply paid lip service to ‘stress’ because it was fashionable, flavour of the month, or because of pressures from a parent organisation. ANALYSIS ACTION ‘AWARENESS’ – What is stress? This means defining what we mean by the ‘stress’ word, and understanding why and how stress is damaging in its consequences. The problem here is one of definition since there is lack of agreement about the meaning of this word stress, and if, in fact, it exists. Stress, pressure and strain are used interchangeably to mean the same thing. Incorrect use of the word stress is common since it is used to refer to a state, a condition, or a symptom. Also, people tend to perceive stress in negative terms. Prevalence of this view is likely to be detrimental to the effective management of stress in the work environment because it is regarded as synonymous with not coping. The outcome is that staff will hide their problems and health condition until they become victims of exposure to stress, rather than actively and positively managing the strains and pressure that are an inevitable part of modern-day living and working offshore. Much of this resistance seems to have been created because the word, ‘stress’ evokes negative reaction and emotion – it has become a four-letter word! Problems seem to arise, because, like love and electricity, we cannot see ‘stress’. Media hype and constant attention have not helped. It has become a whipping boy, blamed for all our ills and problems. To often, stress is now used as an excuse, and stress-related illness is in danger of becoming the ‘back-pain’ of the new millennium. Today I wish to help set this record straight. I want to propose that it will be much more useful and productive for the industry, and beneficial for the men and women working offshore, if we stop using this word ‘stress’. I would like to suggest that instead of using the term ‘stress management’, we begin to think about the ways we can optimise the performance effectiveness, health, satisfaction and happiness of the workforce. In other words, we need to find out what barriers exist to adversely impact upon the productivity and well-being of the offshore employee. This does not mean that we wallow in a negative and damaging, ‘isn’t it awful’ climate because part of the process of identifying barriers to effectiveness is the need to acknowledge the factors that facilitate optimal performance and health offshore. Furthermore, it is important that we acknowledge that NOT ALL STRESS IS BAD. Hans Selye, the acknowledged "father" of stress research said that the only person without stress was a dead person. By this he meant that stress is an inevitable part of being alive, and should be viewed as, 'stimulation to growth and development, challenge and variety – stress is the spice of life'. In Selye's terms stress is simply 'arousal' and so it is any stimulus, event or demand impacting on the sensory nervous system. When an imbalance exists between a perceived demand (the stimulus) and our perceived ability to meet that demand, we will experience a state of stress (i.e. distress). Stress, therefore, is unwanted pressure and is manifest when we feel that a situation is out of our control or when we feel unable to cope. It is a subjective experience, "in the eye of the beholder", and this explains why in a given situation one person might be highly distressed, yet another seems to prosper and thrive. In organisational life it is likely that we are now denied natural outlet of the stress response since we cannot "fight" nor "flee". The Triple ‘A’ Stress Management Model The ‘Triple A’ approach is recommended as a stress management model: This stands for: AWARENESS 195 to ‘burnout’. Having too little to do or a job that does not offer stimulation, variety or challenge are also a sources of stress, known as, ‘rust-out’, leading to boredom and demotivation. Responsibility without commensurate power, a fast pace of work, lack of job control, and uneven distribution of resources are also sources of pressure. Fluctuations (peaks and troughs) in work demand create uncertainty that can be stressful. The introduction of new technology, originally thought to be stressful because it was associated with de-skilling of jobs, is often a potent source of pressure because of the manner in which it is introduced. That is, without consultation, unfit for the purpose or a lack of training etc. A scaled-down workforce is often required to become multi-skilled so that maximum use is made of the costly investment in new technology. Whilst this can offer variety and challenge, it can create stress if the changes are introduced without consultation or reward for extra effort. For the offshore worker, safety concerns, the need to travel by helicopter, and the environmental and physical conditions of the work and living environment have been described as sources of strain intrinsic to the job offshore. We are physiologically primed to take actions that are inappropriate and the sedentary nature of the job further exacerbates this problem. Each of us, at various times during our life, will be vulnerable and will need to know how to actively and positively manage a stressful situation without resorting to maladaptive ways of coping (e.g. excessive alcohol and nicotine; drug dependence; lack of exercise; and comfort eating), which render us less fit to cope with a demand. Thus, it is mismanaged stress that is damaging in its consequences. ANALYSIS – Identifying Stress The identification and measurement of stress at work has been described as the ‘stress audit’. The objective of this type of psychological risk assessment is to identify the negative factors or barriers to performance effectiveness and wellbeing at work, and either eliminating or minimising these harmful sources of stress. Thus, we acknowledge the maxim, ‘healthy work force - healthy organisation’. The word ‘health’ is used in its’ widest sense, to mean not just the absence of physical and psychological diseases, but to describe feelings of well-being, happiness, and satisfaction. To identify the action to be taken is it vital to accurately diagnose the problem(s) (i.e. what, who, how?). Stress audit benefits include: 1. It is a proactive rather than a reactive approach to managing stress at work 2. It can identify organisational and individual strengths and weaknesses and so is similar to an appraisal or training and development needs analysis. Thus it helps us to target scarce resources. 3. Identify the level of stress management required (primary, secondary, tertiary – see below); thus this includes guidance in the planning of organisational development strategies. 4. Provides a baseline measure from which to evaluate subsequent interventions 5. It makes stress a respectable topic for discussion in the workplace. By considering some of the most commonly cited sources of stress it is possible to see that there is not one problem, neither is there one cure. Job role stress For many employees changes to job role structure are common as companies continually re-invent themselves. Often change is stressful because we tend to resist it, but the impact of change might also result in role ambiguity (lack of clarity about the task) and/or role conflict (for example, coping with the conflicting demands of quantity versus quality, or safety versus quantity). Role ambiguity has been associated with tension and fatigue, resulting in leaving the job and high levels of anxiety, physical and psychological strain and sickness absence. Role conflict has been associated with sickness absence, job dissatisfaction, abnormal blood chemistry and elevated blood pressure. • Relationships with other people Having to live and work with other people, lack of privacy, constant company - 24-hours a day, for seven or 14 days at a time can be stressful. Perceived inequity between the oil company and contractor status personnel can create a strain in working relationships. A lack of supportive relationships or poor relationships with one’s crew, colleagues or the boss are stress agents, leading to a low level of trust, low supportiveness and low interest in problem solving. Some personnel, by virtue of their job role are exposed to bullying and violence at work. Reports of this Stress in the Offshore Environment • Stress in the job. Level of demand and workload is a potential problem for many people working offshore. This includes having too much to do, working long hours and shift working (perhaps exacerbated by ‘below strength’ manpower levels) can create overload conditions, leading 196 adjustment at work. Concerns within the family, life crises, financial difficulties, conflicting personal and company beliefs, and the conflict between organisational and family/social demands are examples of potential stressors which might spill over into the individual's work domain, in the same way in which stress at work might spill over and have a negative impact on one's family and personal life. Working and living away from home can be an added source of stress for the offshore worker. Leaving a partner to cope; difficulties with the children; problems unwinding on return home; feeling unable to become involved in community and social activities because of the demands of offshore work, are all problems associated with offshore working that must be actively managed. seem to be increasing and it is likely that the extent of the problem is not well understood. • Career stress. Expectations not met, feeling undervalued and frustration in attaining a sense of achievement are common 'career'' stressors. Ultimately, restricted opportunities for promotion and job insecurity resulting from down-sizing and the increased use of contract labour are potent sources of stress. The ‘slimmed-down’ UK workforce is also an ageing population and the industry faces the issue of coping with this and attracting a new breed of youngsters who enter the world of work with very different expectations than they did 25-30 years ago. Although the stress of unemployment is more damaging than the stress of work, threat of job loss is a potent source of stress linked to several serious health problems, including ulcers, colitis, alopecia and increased muscular and emotional complaints. Also, as the pyramid shape of organisations becomes flatter, and many job levels are removed, there are fewer opportunities for career progression. Finally, in a recessionary climate, training and development opportunities may be restricted. The 'leaner' work-force experience pressures associated with trying to release colleagues for training, in addition to the time off necessary for cover for holidays and sickness absence, while trying to maintain performance, safety and production demands. This creates a demoralised workforce and quite clearly, an under-trained workforce will perceive the work environment to be more stressful and less safe. • Stress in the organisational structure and climate. Simply 'being in the organisation', can bring concerns about the sense of belonging, office politics, social support from the management structure in terms of resources, communication and consultation. It is associated with the threat to freedom, autonomy and decisionmaking imposed by the organisational structure and climate. There is some evidence to suggest that lack of participation in decision-making processes, lack of effective consultation and communication and unjustified restrictions on behaviour are associated with negative psychological mood, escapist drinking and heavy smoking. A culture and climate of threat and/or fear to speak out, simply creates a climate of mistrust, resistance to change, an unwillingness to be innovative or commitment to the vision and goals of the organisation. • Home-work interface stress. Included in this category are the personal life events that might have an effect upon performance, efficiency, well-being and ‘ACTION’ – Options for the management of stress The processes of awareness raising and analysis are necessary steps to guide and inform action. However, too often, stress management courses are introduced as a reaction, in response to a perceived problem within the organization. Other stress management initiatives, such as the use of a counselling service or an employee assistance programme seek to ‘cure’ the symptoms of exposure to stress. This type of stress control programmes focuses solely on the individual and places the onus and burden for change on the employee. The message is loud and clear. It says ‘You do not seem to be able to handle the stress and pressure of your job, so we will help you to cope more effectively’. Whilst these aims are well intentioned, the underlying message to the employee also implies that, ‘we (the organization) are not going to change the way we do things around here. You must learn to cope with the situation!’ Although these approaches to stress control have a certain appeal and can be very effective, stress control can only be really successful if it is tackled at the level of the individual, the team and the organisation – that is, eliminate the source of stress. The strategy of waiting for an employee to become a victim of stress, before taking action, is risky and costly for the organisation from both legal and insurance perspectives. It can also be damaging because it supposes that distressed victims of exposure to stress are either at work and probably behaving in ineffective, non-productive ways, or they are absent from their job, thereby causing extra strains and pressures on the remaining work 197 colleagues or team. undesirable and costly. communication exercises such as role negotiation. 3. Improving perceptions of worker control; this includes increasing opportunities for decision-making. Both situations are A Tripartite Model For Stress Management It is recommended that stress in the workplace should be addressed by adopting a tripartite approach consisting of: Change the Macro-environment This includes attention to issues such as • Organisational culture Building a supportive and open climate and culture, and ensuring that the style of management is compatible with the goals and aims of the organisation, are important in reducing stress at work. It also means developing a culture that encourages staff be more supportive of each other. This will facilitate team working and good interpersonal relationships in the workplace. The benefit of social support as a stress reduction strategy is well documented. It is likely to be an important stress reduction prevention mechanism since external forces prevents us from eliminating certain sources of pressure and strain in the workplace. For example, this would include the need to work shifts, especially night-shift work. An assessment of organisation culture guides the process of culture change. Likewise, the use of psychometric measures to understand the appropriateness of ‘management style’ and its role as a source of stress in the workplace might be necessary • Work overload conditions and long-hours of working It is acknowledged that both work over-load (burnout) and under-load (rust-out – see next section) are potent sources of stress in contemporary organisations. A high workload leads to long hours of working, extra duty shifts, or reduced time-off periods. A re-analysis of staffing levels and an improved (real) costing of the impact of de-manning, or job and task re-design are also recommended to help reduce work overload stress and shift work. Some organisations have found that their enthusiasm for down-sizing has been too zealous, and a subsequent cost benefit analysis has proven the reinstatement of certain jobs to be the most effective management strategy. • The physical work environment In a work overload situation it is important to ensure that employees are not also stressed by the physical conditions of the work environment. In addition to being a source of stress in their own right, they also take-up the attentional capacity of the individual, and the employee is more vulnerable to workplace stress. Research evidence indicates that unpleasant working conditions, the necessity to work fast, to expend a lot of effort, and working excessive and inconvenient hours were related to poor mental 1. Primary level stress management This type of strategy or intervention is ‘stressor directed’ in that they eliminate, reduce or control a source of stress. The aim is to prevent stress at work. 2. Secondary level stress management These interventions are ‘response directed’ in that they help individual employees or groups of workers to recognise a potentially negative response to stress, and change it before it becomes harmful Thus, the aim is to develop stress resistance and adaptive coping strategies through education and training. 3. Tertiary level stress management These forms of intervention are ‘symptom directed’. The objective is to assist in the cure and rehabilitation of stressed employees. Using an, ‘onion’ as our metaphor, we would describe stress management in the workplace, as ‘peeling an onion’. The organisation exists within its universe and is thereby exposed to many different factors. Peel off this layer and you find the organisation, exposed to change and pressures imposed by the global economy, financial constraints, international politics, and legal requirements, etc. All of these, and more, influence the fortunes of the business and the decisions made. A description of each ‘level’ with examples of strategies and interventions, are provided below. Primary level stress management interventions A more commonly used term for this type of stress management strategy is ‘organizationallevel interventions’. Essentially, these ‘stressor’ directed strategies for the reduction or elimination of stress in the workplace are categorised in three ways, namely: 1. Change the macro environment; that is, organisational culture and leadership, physical work conditions and work load, safety climate, career development programmes and bullying at work. 2. Change the micro-environment; that is systems and task redesign, alternative work arrangements, shift working, and 198 Indeed, the stress of insecurity that can be alleviated by supportive working relationships may be broken down if the work force perceives that competition is necessary to retain a job. Personnel may also stay in a job that is unsuitable or disliked because no suitable alternative for change exists. This results in costs to the organisation due to poor productivity or performance • Bullying at work Recent reports suggest that the incidents of bullying in the workplace may be increasing. However, we can not be sure if this now the reality of work life in the 1990s, or due to the fact that people are more willing to report that they are being bullied. Nevertheless, there is an acknowledgement that oppressive behaviour has a negative effect in terms of reduced well being, morale, motivation and contribution to the job. It is suggested that bullies are ‘stress carriers’ within the organisation. Usually these people do not personally suffer from the effects of stress, but their behaviour causes a great deal of stress for subordinates and colleagues alike. Whilst there is no specific health and safety legislation that deals with bullying at work, employers have a general duty to protect employees’ health and safety. In law, it is possible to seek redress for bullying behaviours that generate sufficient emotional distress and unhealthy physical stress. Thus an employer must ensure that the dignity of the employee is upheld, and acknowledge that he or she has a right to be treated with respect. An authoritarian culture, poor work relationships, a lack of clear codes of acceptable behaviours, are all conditions that foster a climate in which bullying is likely to occur. Bullying is often confused with strong management and so becomes condoned and part of the culture of the organisation. It can often be insidious and subtle and so the victim has no witnesses and if there are witnesses they are often afraid of supporting a victim. In some organisations, help-line, helpdesk, employee assistance programmes, face-toface counselling, and the occupational health service, all play some role in dealing with bullying in the workplace. health. Therefore, the work environment should provide satisfying physical conditions. Also a clean and orderly place of work is important for both safety and hygiene reasons. This has implications for the morale of the work force, especially in an environment where the work situation is acknowledged as hazardous. Clearly, many of the opportunities for the prevention of stress associated with the physical demands of working exist at the design stage, and of course, in the provision of adequate personal protection equipment. Complaints about the lack of ventilation, or conditions that are too hot, too cold or too stuffy, are common, and in the offshore environment this is exacerbated by the perceived lack of personal control over physical work conditions. Whenever possible, the practice of more open discussion and debate about the issues that directly affect working conditions should be encouraged. This includes the arrangements for rest and lunch breaks. The work environment should be perceived as comfortable and safe and a high standard of hygiene and cleanliness is desirable. • Safety climate Many individuals offshore are exposed to certain dangers and hazardous conditions at work. While a risk assessment allows us to control and minimise these dangers, some jobs still have inherent or perceived dangers. For example, the safety of helicopter travel was identified as one of the top ten sources of stress by offshore oil and gas workers (Sutherland and Cooper, 1991). Also, among Norwegian offshore workers, more than one third reported that they felt unsafe about the transportation of people by helicopter (Hellesøy, 1985). The perceived risk associated with helicopter travel was the most common reason cited for resignation from offshore employment in Norway. This action is costly to the industry and helicopter travel remains a reality that must be faced by these workers since we do not yet have any means of ‘beaming people through space’. However, education about the nature of the risk and safety performance might help to overcome the irrational fears that are held. • Career development. Fear of job loss and threat of redundancy are common features of contemporary working life. Perceived or real, pay and job status inequity, lack of job security or limited potential for future career development are sources of stress. In times of instability, poor work conditions are tolerated and employees endure long hours and arduous conditions. This does not happen without personal and organisational costs. A keen, competitive jobs market can threaten the quality of co-worker relationships at a time when social support is of particular importance. • Change the Micro-environment Rather than put the responsibility for stress management on the individual employee, exposure to stressful work conditions might be reduced by the redesign of work systems and practices. It is suggested that work redesign can improve worker morale, motivation and performance. Although many workers complain about having too much to do, or having to work at a pace that is too fast, they also complain that the job does not provide enough variety or challenge. This can lead to 199 ineffectiveness caused by behaviour that an individual is unwilling to change, because it would mean a loss of power or influence. This method works because most people prefer a fair negotiated settlement to a state of unresolved conflict. Thus, they will be motivated to engage in some action themselves and make concessions in order to achieve this aim. • Improve perceptions of worker control Lack of job control is acknowledged as a potent source of stress and perception of control seems to be important for job satisfaction, health and well-being. A variety of strategies exist to improve perceptions of worker control and increase the opportunities for decision making at work. These include building and developing semi-autonomous work groups, quality circles, safety improvement groups and health circles. Ultimately the aim is to for the work force to be empowered and involved in changes to any system or practice that induces stress at work. This is to create a better balance between the perceived level of demand and worker control. • Increase worker participation in decision making Lack of participation in decision-making is a primary cause of role conflict and role ambiguity, mediated by one's perceived influence over the situation and the efficacy of communication in the organisation. Feeling controlled rather than 'in-control' is associated with a state of stress; individuals who feel controlled are likely to perceive their job as a 'strain' rather than a challenge and source of motivation. boredom, apathy and low motivation to work. Thus, job redesign interventions can be used to alleviate the problem of ‘rust-out’ in the workplace. • Work under-load: Under-stimulation and boredom Prevention of stress associated with ‘rust-out’, due to boredom, and lack of stimulation in the workplace can be achieved by changing the ‘micro’ work environment. This includes increasing workers' skills, autonomy in the job and providing more opportunities for decisionmaking. By re-designing or enriching the job, to improve the amount of skill variety, task identity, task significance, autonomy and feedback, it is possible to improve both motivation and job performance and reduce levels of stress. Decisions to make this type of change are usually made on the basis of a job analysis, in conjunction with work force and jobholder discussions. Job enrichment intervention strategies can increase job satisfaction, improve production, and reduce job absence and turnover. • Reducing the stress of shift-work The need to engage in shift work and work long hours is the reality of work offshore, and the spill-over impact can cause negative consequences and costs for the family and society itself. Thus it becomes a prudent part of a stress management strategy to minimise the impact of these potential sources of strain and distress that cannot be eliminated from the world of work. These options include the design of the shift system, flexitime, selection and recruitment for shift working, stress management education, and physical interventions such as the use of light therapy and the drug, melatonin. Clearly, the need to work shifts represents a major source of stress among offshore workers but it is likely that individuals do habituate to shift work and it becomes physically less stressful with time. However, some work patterns might prevent habituation occurring. Thus, there is a need to follow guidelines provided for minimising the negative impact of shift-work and long hours of working. • Reduce role stress The constructs of role ambiguity and role conflict are acknowledged as potent sources of stress in the work environment that are associated with a variety of negative attitudinal health and behavioural outcomes. Thus role clarification interventions can be used as stress control strategies. For example, a role clarification intervention was used in an engineering company to improve employee communication and manage stressful work demands. Role negotiation is a useful way of overcoming the problems that lead to Secondary level interventions Although a growing body of evidence supports the view that organisational-level stress control and stress prevention interventions are more effective than individual-level coping strategies, because they have a more lasting effect, it is clear that the prevention of all sources of negative stress is not possible. Thus, the effects of exposure to stress can be minimised by the use of techniques to improve the stress coping process. They are classified as ‘skills training options’ and ‘healthy-lifestyle education and management’. Skills Training to Cope with Stress The objective of skills training is to improve or modify the individual's response to perceived strain to avoid a negative outcome. This includes: 200 • • • • • • • Interpersonal and social skills; leadership skills Assertiveness Cognitive coping techniques, e.g. avoiding faulty thinking Time management Relaxation training, meditation, yoga, and biofeedback Type A behaviour management Anger management • Time management As we have acknowledged, an ever-increasing volume of demand and pressure to do more and more, in less time, and with fewer resources, are ‘hot-spot’ sources of stress in contemporary organisations. However, a demand situation is only defined as stressful when the perception of that level of demand exceeds the perception of one’s ability to meet the demand. Thus, the goal of time management is, to ‘work smarter not harder’. • Relaxation The purpose of relaxation training is to reduce the individual's arousal level when exposed to a source of stress. This technique is used to bring about a calmer state of affairs, both physiologically and psychologically. Psychological benefits include a sense of personal control and mastery, a reduction in felt tension and anxiety, and an enhanced feeling of well-being; physiological benefits include a decrease in blood pressure, slower respiration and heart rate, reduced muscle tension, less stomach acid, lower cholesterol in the blood and increased alpha and theta brain waves to enhance creative and cognitive processes. • Type ‘A’ behaviour management In the late 1950s, a pattern of behaviour among heart attack survivors, called 'Type A behaviour' was observed. It is now acknowledged that the Type A Style of Behaviour, referred to as 'TAB', is a risk factor for heart disease, independent of heredity factors (i.e. high blood pressure and cholesterol levels), cigarette smoking, alcohol consumption and obesity. Recent research suggests that it is the hostility component of TAB that is the factor that increases the risk of heart disease. TAB appears to be a response to a challenge in the environment and is a way of coping which the individual finds rewarding. Although the long-term impact is likely to be costly to the individual and the organisation, the immediate outcome is one of gain from these workaholic individuals. • Anger management The inability to manage recurrent angerprovoking situations is associated with impulsive behaviours, aggression and • Interpersonal and social skills training Everyone has a vast capacity to being more understanding, respectful, genuine, open, direct, and concrete in his/her human relationships. With a sound body of theoretical knowledge, appropriate models, and numerous opportunities for personal experiencing, the process of becoming more fully human can be greatly accelerated. This is the essence of interpersonal skills training. It includes a range of communication skills and the need to understand the barriers to good communication. Interpersonal skills training are usually key components of leadership training. • Assertiveness Having to deal with other people as part of one’s job can be one of the most stressful aspect of working life. For example, having to convey a decision that you know your staff will not like; having to handle an irate customer without losing valuable business or making promises that are difficult to keep; or, being faced with unreasonable work demands or time deadlines. Assertiveness training helps us to deal with such demands without becoming angry or upset. Assertiveness training teaches us to be able to speak-up and be taken seriously without damaging the rights of other people • Cognitive coping Occupational stress is now viewed as a transactional process whereby employees appraise and react to a potential source of stress. Cognitive style influences our appraisal of a potentially stressful situation and the coping strategy subsequently used. The use of certain coping strategies, such as ‘avoidance coping’ or denial is associated with poor psychological well being, whilst the use of problem-oriented coping is linked to positive mental health. The use of cognitive restructuring as a stress management technique aims to examine dysfunctional attitudes and irrational thoughts. The process aims to improve the balance between perceptions of a demand and our ability to cope. 201 Tertiary level interventions This type of intervention is directed at symptoms of exposure to stress. It is concerned with the rehabilitation and recovery process of those individuals who have suffered or are suffering from ill health as a result of stress • Counselling services Counselling services typically help the individual employees deal with a particular personal or work-related problem. Thereby, they attempt to increase the employee's capacity to withstand the perceived stressor. Counselling is described by the British Association of Counselling as the task of giving a client an opportunity to explore, discover, and clarify ways of living more resourcefully and toward a greater well-being. • Employee assistance programmes An organisation contracts an Employee Assistance Programme (EAP) provider to give employees (and sometimes their immediate families) access to an external, independent, confidential advice and s short-counselling service. EAP counselling is for individuals with work related problems, relationship difficulties, illness worries, redundancy or retirement concerns, substance abuse, or financial worries, etc. Typically the function of an EAP is to assist in the identification of problems that lead to impaired job performance and constructive confrontation of the issue. Ultimately the objective is to improve job performance • Training supervisors and managers in basic counselling skills Knowledge that a spouse or partner is unhappy may affect one’s performance, safety or wellbeing. Management sometimes prefers to regard these issues as ‘none of our business’. However, an important part of the management process is ensuring that there is collaboration with employees in order to remove any barriers that exist to adversely impact upon performance and productivity. Distressed employees who are anxious and depressed because of worries about home are likely to be ineffective, potentially unsafe, and often disruptive when they are at work. By helping the individual to resolve a homerelated stress problem quickly and efficiently, the manager regains an effective worker. Making stress a respectable topic for discussion in the workplace is the first step in this process, because a climate of trust and openness is necessary for the exchange of potentially sensitive information. Therefore, supervisors and managers need training in basic counselling skills. cardiovascular disease. Suppressed anger is viewed as maladaptive and also associated with cardiovascular problems. Whilst stress inoculation interventions may help to reduce the stress response when the individual is exposed to difficult conditions, anger management courses may also help to avoid undesirable behavioural outcomes. Also at the ‘secondary level’, options are available that aim to keep the individual fit to cope with the pressures of work and living. These include stress education and awareness programmes, and on-site ‘healthy-lifestyle options. • Stress education and awareness raising These programmes are designed to increase knowledge about stress, to increase awareness of links between stress, illness and personal behaviour, and improve personal stress coping skills. Promoting self-awareness helps the individual to take actions to reduce their own stress levels. This is usually offered with follow-up programmes such as, skills training, relaxation, assertiveness and keep-fit programmes. • Healthy lifestyle options for the management of stress In addition to stress management training, many companies have adopted health promotion as an attempt to keep employees healthy. These include weight control and dietary advice, smoking and alcohol cessation, hypertension reduction, substance abuse clinics and fitness programmes. • Exercise and fitness programmes Employee exercise programmes are probably the most popular forms of stress management activities offered to employees in the workplace. They are usually offered to as a way of reducing sickness absence and improving work performance. As our understanding of the effects of work-related stress increased, it is accepted that our increasing sedentary lifestyle is a contributory factor to ill-health and a sedentary lifestyle is associated with increased risk for coronary heart disease. Benefits of exercise and fitness programmes are in terms of a decrease in absenteeism, staff turnover, and improved staff morale and productivity. Reductions in levels of anxiety and depression, improved mood states are reported and employees say that they feel ‘better’. They also report fewer symptoms of stress and perceive the organisation more favourably. 202 • Social support as a stress reducer The value of emotional support in one's social network as a protection against adverse environmental forces or negative life events is well documented. Social support from one’s fellow workers and supervisor appears to moderate the effects of job stress more effectively than support from one’s family and friends and there is much evidence to suggest that social support can play a significant role in enhancing the level of employee well being. It is necessary to emphasise the importance of supportive relationships and networks during the selection process in order to promote a desirable climate and culture, since this affects the quality of working relationships. Thu, a supportive image should be encouraged, reinforced and acknowledged as criteria for recruitment into the job. Managers and supervisors should be selected and trained for their ability to understand the need for social support and reflect it in their style of supervision. Structures to provide support include access to an occupational health and counselling services and social networks and self-help groups need to be encouraged. • Career sabbaticals The opportunity to take a career sabbatical can help an individual to recover from the effects of stress. With so many people today working to the point of exhaustion, organisations should encourage staff to take sabbaticals to recharge themselves, ideally, before the individual becomes a victim of stress. 4. 5. 6. 7. Conclusion It is worth remembering that pressure is an inevitable part of living and working, but distress is not! Whilst our lives will continue to become more complex and change will continue to be a feature of life in the 21st Century, we must remember that not all stress is bad. It is a vital part of being alive. Ultimately, we might need to concede that is no longer useful to use this word ‘stress’ and the term stress management, because ‘stress’ has a negative image. Employees do not like being labelled, ‘stressed’, or ‘non-copers’. Organisations do not like causing ‘stress’ to their staff. In reality, stress management simply means identifying all those barriers that exist to adversely impact upon the performance effectiveness at work, and the satisfaction, health, well-being and happiness of personnel offshore - IT IS ABOUT MANAGING ONE’S BUSINESS EFFECTIVELY. Nevertheless, as a generic way of discussing how we can optimise performance effectiveness at work, and the satisfaction, health, well-being and happiness of personnel offshore, it is a useful shorthand phrase to use until we can find another less emotive label. An integrated model of stress management It is desirable that organisations will use proactive, preventive AND curative approaches to the management of stress, and at the same time operating at more than one level. 1. 2. 3. and what they need to be more effective, productive and healthy as employees. Define who is to be involved in the initiative, the project champion, how it will be staffed, who will be involved, and what will you need from each employee. The project must be endorsed at the highest level to gain commitment to the initiative and subsequent change. Communicate your intentions in a clear manner – verbally, visually and preferably, more than once! Provide guarantees of confidentiality. Define and communicate how the feedback of results of a stress audit or risk assessment will be used. Successful Stress Management Have a clear idea about why you are becoming involved in a stress management programme. Identify clear objectives and goals. For example, is your objective to reduce sickness absence or accident levels? Decide how you are going evaluate measure the benefits. Share rewards with employees to sustain a culture and climate that acknowledges the link between employee well being and business effectiveness. Take the time to understand staff attitudes to the stress management policy and strategy. Ask employees for heir opinions Both preventive and curative stress management strategies are essential in an organisational approach to stress control in the work place. Increasingly, evaluation studies indicate that prevention is more effective AND cheaper than trying to cure problems and victims of exposure to stress. Undoubtedly, stress management in the workplace must be the joint responsibility of both the organisation and the individual. Both parties have a duty of care and need to exercise 203 this obligation in order to remain healthy and free from harm. Ultimately, the effective management of potential sources of stress is about being in control of the pressures in one’s life. QUESTIONS AND ANSWERS SESSION Question – Dr Ron Gardner, HSE Actually it’s more of a point I’d like a view on. Very interesting when you said you felt a stress policy should be integrated with the general policy. We’ve found with traditional hazards it’s more effective to have a set policy on that topic as it focuses the mind. I think the big difference is that the management is usually the stress problem so I think you’re right in this particular case but I’d just like a view. The second thing is, I think you are also right to put health as the tertiary end of this. I tend, (although we’ve got the topic covered at this conference), to think of stress as a management issue rather than a health issue. Whilst change will continue to exert a considerable force on our working lives, it must be acknowledged that some degree of pressure is inevitable and can be spur to improved performance and motivation. Stress is a dynamic process and this means that stress management is not a one-off project. It must become an on-going process within the organisation. To be successful it must become part of day-to-day management and practice, and embedded within the culture of the organisation. Ultimately this is the only effective and cost efficient strategy to avoid the unacceptable costs of distress in the workplace. Answer – Dr Valerie Sutherland, SutherlandBradley Associates As I said, I do get asked for help in how to write a stress management policy and I don’t really think that’s the way to go. I think if you have a good health and safety in the workplace policy and policies for the way you manage your business, that actually should cover what you need to have in place. My only concern is that this stress activity just then becomes an isolated issue which is given to some poor project manager who is targeted as the stress management manager. They are forever almost like a leper pushed into the cupboard because everybody else would rather get on with what they see as the more important business of the day. So that’s my only warning on that and what I see going on in lots of other businesses, certainly not just in the offshore industry. It’s the same onshore as well. We need to understand the nature of stress at work before we can eliminate or moderate it. A stress control programme can be effective if resources are targeted to specific problems and aimed at the elimination of the source of stress. Organisations who recognise the high costs of mismanaged stress in the workplace and seek to achieve enhanced levels of effectiveness and the well being of their work force, will adopt this integrated approach to stress management. It embraces both individual coping and organisational change to combat the problems associated with stress at work.

So do you think that could be a deterrent for reporting stress? QUESTIONS AND ANSWERS SESSION Question - Jake Molloy, OILC Offshore Union You say that Kathy Parkes’ research suggested a 4% increase in stress cases. Could it be that in actual fact there is significantly more and a degree of under reporting? The reason I put 206 point with this research was that it tended to point towards an increase, without explaining at the present time why that increase has occurred. Answer – Ronny Lardner, Keil Centre I guess that’s possible. I guess the other thing that we need to remember is that in any organisation no matter how well run it is, you will get incidences of mental health problems at any point in time.

However, I have to say that in that sort of case, it would probably have been referred to us some months before. We would prefer that a manager or an occupational health doctor actually made a referral and in the process of referral engaged the employee’s consent for ICAS to disclose to that one person for example on a need-to-know basis. I think to be able to have a clinical discussion about the client’s issues in front of a whole panel of people would also be somewhat questionable. QUESTIONS AND ANSWERS SESSIONS Question - Tony Garner, Conoco You say you’re a good provider and seem to differentiate between good and bad EAP providers. How do you know you’re good because it’s so difficult to audit EAP because of the confidentiality issue? By definition, occupational health/human resources don’t really know what you are doing. Answer - Dr Stephen Galliano, ICAS Group Did you say Conoco? I just wanted to check where you came from because we’ve just managed to survive a major audit by DuPont and they sent in their heavy troops from the US and we’re expecting companies like Conoco and our oil customers to do exactly the same. We’ve had probably about four or five audits every year. The auditors up till now, most of them have been Americans coming in working with occupational health in the UK. So we’ve had occupational health doctors viewing our cases, viewing our workflow, studying our procedures, looking to see whether we implement the procedures that we have written down, interviewing our affiliates, checking out their credentials, checking out what they think about us as an EAP provider. We’ve also had one audit, which has involved UK-based auditors. That has also gone well. An audit is possible, and audits are done. All EAPs should be audited at least every two years. You can find out a great deal about it through an auditor, if you know what you are looking for, and I take your point. I often leave it to occupational health doctors to say what they want to say to HR and line managers. We will disclose everything with occupational health and I know that they will give as little information as they can, but enough to make the determination about fitness for duty etc, work safety etc. So the answer is ‘yes’, you could have somebody at a case conference, but you would need some kind of consent from the client to be able to disclose any clinical personal data. Question - Bob Hanson, BG Group You made reference to the fact you train counsellors? Are these lay counsellors, people in the workforce? Answer - Dr Stephen Galliano, ICAS Group Within the context of the harassment exercise? Answer - Bob Hanson, BG Group? Yes. Question - Jim Johnson, Shell UK Just on the point of confidentiality. When we have a problem with an employee we tend to have a sort of mini case conference where we typically bring in OH, HR and the line. It would be useful and perhaps reduce a sense of standaloneness of the EAP if they could join in these things. Would you have to have the client’s express permission before you take part in such a mini case conference? Answer - Dr Stephen Galliano, ICAS Group We didn’t call them counsellors. They were called listening posts but nobody wanted to describe them as listening posts, so the organisation was quite keen to call them harassment counsellors but with a very clear brief, supervised on a regular basis by the way. We did train them. We did a whole series of four-day counselling skills programmes and we did a top-up every year for them. Answer - Dr Stephen Galliano, ICAS Group That is if we are already consulting the client and helping that client? Question - Bob Hanson, BG Group And did their colleagues feel happy about using them? Answer - Jim Johnson, Shell UK Yes. Answer - Dr Stephen Galliano, ICAS Group The policy was quite well written up really and it allowed for people in certain business units to contact a harassment counsellor in another unit so they were not expected to be talking to their own colleagues. They’d set it up in as independent and safe a way as possible really. There was a published list in the organisation Answer - Dr Stephen Galliano, ICAS Group There has to be consent for any one of us to disclose any information about the client so yes, you need the client’s support for us to do that. It would be totally unethical for us to 212 with the locations of all of those people, so the idea was they would ring somebody who was three hundred miles away in another site rather than in their own location. 213 214 FEEDBACK AND DISCUSSION – HUMAN FACTORS AND PSYCHOLOGICAL HEALTH – WHERE NEXT? Introduction to Video Session – Ronny Lardner Just a little bit of introduction to this video. It’s intended really as a concrete example of how an organisation can perhaps bring together many of the things we’ve discussed this morning in relation to stress. This is particularly relevant to the awareness part of dealing with stress. The history of this is that it is something that occurred in your own industry where back in 1998 BP at Grangemouth had some issues about stress. There was an analysis, an action exercise carried out there to identify what were the main work-related causes of stress and those were addressed. At the same time it was realised that there was a need to raise awareness amongst the whole workforce about the site’s position on the topic of stress and what was available locally to deal with it. Answer - Tony Garner, Conoco I thought it was a bit on the negative side whereas Dr Sutherland was very much on the positive side of stress. Stress is very important, a very good tool, it’s a very motivating subject and that was a negative impression of stress. Stress isn’t negative. Question - Ronny Lardner, Keil Centre Any other views on that, on the overall message that came over? Answer – Dr Ron Gardner, HSE It’s a little focused on the individual. It was nice to hear you say there had also been seminars and materials for managers, but what managers could actually do towards the process didn’t really come out of that at all. It was very person orientated. I was a member, along with many other BP employees of a working party, a vertical slice throughout the organisation including safety reps and process operators who had the task of putting together an educational programme for the site about stress. The final product of this was a video, an intranet website, booklets for every employee and also a poster campaign. That was followed up by seminars for managers, team leaders and safety reps, in short everybody who had responsibility for other people. Answer - Ronny Lardner, Keil Centre It’s interesting you should say that. At the time our intention was to try and get the message over about the importance of preventing things rather than it being an individual – a subject that was purely about individual coping. We thought we made great strides in doing that by getting the senior management to endorse it and allow inclusion of that sort of message. I think perhaps things have moved forward a bit since then and now people would be looking for a much stronger preventative message. What we are going to do is look at the video. Bear in mind that it was produced three years ago and maybe thinking has moved forward a bit since then but at the time it was believed to be the right message to put forward. I would be interested in getting your views after we’ve seen it about whether you agree with that. Question - Dennis Krahn, International Association of Drilling Contractors In that situation you had the ability to go offsite. In an offshore location you don’t. Could you talk about the difference in the situations and what we might do about that? - Video shown to delegates. Answer - Ronny Lardner, Keil Centre Is that in a sense Dennis that employees have the ability to seek support offsite? Question - Ronny Lardner, Keil Centre On the basis of what we’ve listened to today and your own personal experience do you think that video promotes the right sort of message from an organisation about work related stress? Does anybody have a view on that? Question - Dennis Krahn, International Association of Drilling Contractors That’s correct, implying perhaps that initially there may be some shyness to be seen to be taking advantage of these resources. If so, then your only recourse is to go where your shyness doesn’t matter, where nobody but 215 Dennis has raised an important question, but we’re here today for one particular thing. We’re talking about offshore and there are differences. I think really we want to open up the debate. We’ve got a panel of speakers here and really what we should be doing is sharing the views because I think there’s a silence in stress that is ready to explode in this industry. I think the one area that certain people have got to deal with, particularly in dealing with occupational health, is stress. yourself can see. Is that a factor in getting to the state of play offshore that we would like to be at? Answer - Ronny Lardner, Keil Centre Yes, I’m sure the fact that it’s a lot more difficult to access resources confidentially if you’re working offshore for a fortnight at a time is very relevant. I guess perhaps people store that up until they come back onshore. One of the intentions of the video was to try and help remove some of the stigma that’s associated with stress, so it’s a legitimate subject for conversation. Personally I used to be in the police service. I was in the police service for twelve years and at that time the notion of mentioning or discussing that you might be experiencing stress would be completely out of the question. It would just not be a subject that you could have raised and discussed because it would have been viewed very much as though it was about your individual ability to cope. It wouldn’t really be a legitimate subject. So, one of the things I wondered of the audience was, do you think something along those lines actually helps to remove the stigma that is attached to the topic of stress and legitimise it as something you can discuss? As Ronny says, it’s three years ago. BP has done this on their refinery at Grangemouth. Dennis has raised an important question that will be in everybody’s mind. There was also the question from Conoco which I thought Stephen in a sense had answered - how do you think you’re doing well? Well it’s up to the organisations that take you on to audit. In general let’s open up for the panel and if anybody wants to, throw in questions about stress. How we would handle it? How we would tackle it? Bear in mind that our aim is to share views, challenges and successes and look at research studies. Comment – Una Corpe, Shell Expro I’ve been involved in stress management at Shell for about 10–12 years and this is comment rather than a question. We’ve done large-scale research in the past. It’s taken maybe 12–18 months to do some research and then to get our final figures. To carry on from that, we looked at EAP programmes, many of them in the UK and we looked at some experience in one of our own Shell operating companies further south. We really didn’t find it beneficial. Going back to the speaker’s comments of good and bad EAPs, we didn’t find EAPs particularly helpful at that time. Because there were particularly maybe good to the individuals, but not particularly good to the organisation for the management of stress, whatever the causation was. Comment – Mr Kevin O’Donnell, HSE I tend to agree with you there. If you see the video as part of a package, some of the aspects describing the symptoms of stress are useful. People here are probably reasonably well educated as to what these are. A lot of people in the workplace may not realise very simply what the symptoms are that they are experiencing and having it explained at a very basic level, as Ian and Tony did, is a very good starting point as an overall package, not just on its own. It’s got to be remembered that the video isn’t standalone, it’s got to be part of a package for a whole set of issues. Question - Ronny Lardner, Keil Centre I guess the final question I wanted to ask the audience is do they feel that their own organisation would endorse that general sort of message about the subject of stress? Would that be the sort of message you would endorse putting over to your own employees, or would there be a different type of message you would want to put over? We haven’t seen much development from that as such. What we’ve done within the organisation is we’ve used the ‘Triple A’ management approach that Dr. Valerie Sutherland has described. We’ve more or less had that system in force for probably about five years. Now what we do; we do real time measurement; we do the ‘Triple A’ approach as regards the education and awareness; we do the stress research in real time where we include GHQ and the HADs mental health questionnaires in all of our health screening. In addition to that, we do surveys for any areas Chairman – Rab Wilson, AEEU In essence, what the video was for me, was giving the opportunity to show you what BP is doing. Now whether we like it or not, BP is identifying that there are problems with stress. 216 management initiative and you’ve got pretty firm views of how you want to roll that initiative out, then it would be pointless to get an off-the-shelf programme coming into your organisation because it wouldn’t integrate that well with your requirements. that consider they’ve got hot spots onshore or offshore throughout our organisation. The figures that we’ve got on this real time stress analysis are about 14-15% which compare with Kathy Parkes’ figures from about four to five years ago which we were part of her study and which haven’t increased since then. If you want GHQs and HADs and whatever else done for all those employees presenting to an EAP for example then I think you can, if you specify that, and if it fits in. It has to be upfront but I have to say you need to position it very carefully. One of the problems that exists in the market is that you get customer organisations saying okay, we want an EAP. Let’s invite proposals and let these people send us one of their proposals and it’s often not easy to try and understand the real motivation behind the EAP. It may not be that easy to understand why the organisation wants an EAP and in fact how far the organisation is going to roll out an effective stress management programme. But it’s sad that you had that experience I’ve got to say, and it’s regrettable. We look closely at our stress measurement within the organisation and integrate it into the management. There are one or two of our areas where we’ve got hot spots. We’ve had hot spots on offshore installations and one of them in particular that had fairly high cases rates was actually one of the areas that had an EAP type programme in place. So, using our ‘Triple A’ approach for reinforcement in that particular area, the levels have come right down to the 14-15% for the company as a whole. Going back to the EAP programme again. In our experience that system wasn’t integrated. We weren’t able to integrate that system into the company because of the confidentiality element. Not to do away with the confidentiality to employees, but to release information to management as a whole, you need to be able to have more real time intervention so as to do something about it. Because, if the individuals go off sick with stress that may be the first time that you find out about it, if it’s just an EAP programme that’s in place. Comment - Dr Valerie Sutherland, Sutherland-Bradley Associates I have been in the fortunate position to be able to speak to a lot of the guys and fewer of the women who work offshore and certainly not to admit to being under stress is something that comes over quite clearly. What they also tell me is that they don’t have anybody to talk to when they’ve got problems. When you tease that out a bit further they probably will go and talk to somebody like the radio operator or the medic. So I think that’s a resource and Stephen’s going to hate me for this, but we should consider training somebody like that in some basic skills. We need to acknowledge that they can’t provide the full gamut of a counselling service offered by an EAP, but they can provide help. We measure sickness absence within our company. I said at the beginning of this conference that our sickness absence rate for Shell Expro is one percent. We look at the causation of absence and looking at the causation of absences of 28 days or over, stress and backs are the main problems. They are a very small proportion of the total, but in saying that, if somebody actually goes off sick with stress, they’re off for at least six months. What we need to do is have an early intervention programme which is a total ‘Triple A’ management approach, which is what we’ve got in operation and which works. If you’re on a rig for fourteen days and you have a problem, and you’ve got to sit there for another thirteen and stew about it, well that’s probably a person who is an accident looking for a place to happen, so I do think you do need this. You can’t go (as they do in BP Grangemouth) to another building tucked away in a corner of a site somewhere. It’s got to be something that people can do. There is access to telephone services with EAPs. Maybe that could be used more, but then there is still this issue of confidentiality. That’s my point on EAPs. Comment – Dr Stephen Galliano, ICAS Group I think one of the challenges when you’re looking for an EAP, (well an external EAP because a lot of organisations have internal programmes equally but not more effective and powerful than external ones) is trying to decide what you want the EAP to do, and how you want to position the EAP. I think if there is a very up front substantial stress I do want to say something about getting to people quicker before they become sick which 217 for those who haven’t got the ability to fall back on an EAP programme themselves? You talked about basic training for the medics. It seemed to me that the medic or the OIM, should surely have some sort of responsibility here – probably the OIM - because he is responsible for everybody’s health and welfare on the platform. I can understand there are some pitfalls involved, but how would we go about trying to ensure that all the people that you have working on your platform can get some stress counselling? I agree is absolutely crucial. We are in prevention here and being proactive. Part of my notion of integrating something into dayto-day systems and practices is that there’s got to be some mechanism where people either as individuals, or in a group, can just simply reflect without even using the word stress. How am I doing? Am I effective? If I’m not effective, why not? If I don’t feel job satisfied why not? Then you’re going to tease out the reasons for this. If that’s done, I guess I’m saying a bottom-up driven model, they can then go to a supervisor, or crew manager, or whatever you like to call them, and then sit down as a group and say can we do something about this? Can we take the heat out of this situation? I don’t think we really tap in enough to people out there and ask their opinions of what they want done and how they would better manage their stress. I feel, because we’re all so busy all the time we’re rather like hamsters aren’t we running in this wretched wheel and hamsters just seem to do it for hours and hours and hours and hours. It’s not just offshore this is a criticism of, it’s all the other places I go onshore. We just don’t seem to be able to get out of that wheel and think about what it is we’re doing. A lot of the time we look around and think if I could just stop for a few minutes and reorganise myself, things would just be so much better and less stressful. But we seem to be on this madcap go go go all the time and that’s what I think is creating a lot of stress. Chairman – Rab Wilson, AEEU There’s somebody else who has got a question and we’ll ask it because you’ve asked the panel on their views on the multi-skilling one with stress. There’s another question as well and we could take two questions so that the panel get the opportunity. Question - Gareth Powell, BP I’m in design but I’m an offshore medic, so it’s relevant to both the last points in a way. Certainly within BP we do have training in basic counselling and stress management skills, but you need to remember the situation offshore, that we’re offshore for fourteen days with these people as well. Whereas some people are quite comfortable to come and talk to us about problems in their personal life or their work life, there are others for whom we’re just a bit too close. They’d much rather speak to someone they don’t know, a bit more distant on the end of the telephone. I certainly think that’s where EAPs are invaluable. I’ve had experience over the last couple of years of people that have used both those routes with equally good outcomes. Chairman – Rab Wilson, AEEU We are here today, in particular to listen to you and you’ve been very patient out there. Just a couple of thoughts for debate here. I’ve been given something here. In your organisation do you have any work-related stress cases? Are these treated as LTIs? If not, why not and would doing so help address the root causes? It’s something to think about but because we’re here to listen to you and the speakers have had a fair bit today, maybe if we take one or two questions and open it up. Answer – Dr Stephen Galliano, ICAS Group I wanted to make a comment in fact, initially in response to this gentleman’s question about offshore workers and how do they get to see somebody offsite and partly to this last question. I think that all of our oil customers allow access to the EAP to the contractors as well. I can’t think of any of our customers that don’t to be honest with you. It would seem that they also pay for that, i.e. it’s not the contracting companies that are paying for the service, but that the oil producers have taken the view that the contractors are working on producers’ installations, producers’ platforms. It’s the producers’ responsibility and therefore it is important that contractors also have access to certainly at least the telephone services when they’re offshore and all the rest of it when they’re onshore and that their families also have access to it. Question - Ian Loughran, Phillips Petroleum Within our organisation, people who work for Phillips have got access to an EAP through their health care if I remember rightly. What are the panel’s thoughts about the fact that with multi-skilling, that it uses contractor workforces etc. which means you’ve got people who’ve got different terms and conditions and may not have access to EAPs? How can the duty holder try and deal with this issue to try and bring stress out into the open 218 contractors to access. But we’ve found that there is a barrier, there is a psychological barrier. It’s very difficult sometimes to pick up that telephone and there is clear evidence that many people pick up the telephone and put it down again before it actually gets answered. What we are trying to do there is look at, in cooperation with our EAP provider, alternative portals. We’re looking at the use of the web, we’re looking at the use of chatrooms and using any technique that people will feel comfortable with to get this help that we’re paying for. I know that these people use our services. There are telephones on platforms, though conditions are better in some than others in terms of how much privacy you get, how many lines there are and how many telephone points there are. I have to say that we do get regular calls from the platforms. The only problem we experience is that the contracting companies tend not to join in in the promotion and implementation of those services to their contractors. Therefore, what we do now is go offshore on a fairly regular basis and do presentations offshore to the managers, supervisors and to all staff, whether they are contractors or employed staff. The other issue is using your EAP. Not every offshore worker lives in Aberdeen. My workforce is spread throughout the UK and near Europe and I have a great benefit in using the EAP. Our EAP has a very good network of psychiatrists, psychologists, specialist counsellors. We have been using those for therapeutic reasons to provide us with the psychological support network where we can refer where necessary. This is a service I can offer to general practitioners when managing our cases as well. I suppose the end of it is that you have to integrate the whole lot. Include the medic training - we certainly have done that. Include the management training as well. Keep it in the public domain. Keep it in management’s view. Finally, try and stop management taking unthought out initiatives, because there’s one sure thing, there is no magic bullet, but that doesn’t necessarily stop many of our managers going in search of it, somewhat like the holy grail I suppose. Comment - Dr Valerie Sutherland, Sutherland-Bradley Associates My comment is to the gentleman from Phillips. I agree with Stephen on that. I presume, unless you specify that all your contractors provide a service for their employees, then probably you are going to be it. Question - Dennis Krahn, International Association of Drilling Contractors I would like to ask a question relating stress to safety performance. In the drilling industry we’ve had, I can recall, three very serious incidents where it seemed like the team knew what to do, but they didn’t do it. One of the team didn’t do something right and nobody else called that out. Training seems to have been okay, management tells them to take time out for safety and not to hurry, so my question is this. Is there some amount of stress that we haven’t identified that causes them to lose situation awareness such that they almost don’t see that it’s wrong; or like it’s disembodied they see it’s wrong but it’s not going to happen to them, or they’re for the moment immortal or something. Can you help us to understand this perhaps, this relationship? Comment - Ronny Lardner I’m just going to comment on I think it was Dennis’ point about incidents where you wonder whether stress played a part in it. I guess the only thing you can say about that is it’s very difficult to determine after the event whether that’s actually the case and it would simply be speculation on my part to comment further on that. I think it’s very difficult after an incident has taken place to determine with any certainty whether, for the individuals involved, being under stress was relevant in individual cases. Comment – Dr Jim Keech, BP, Chairman of UKOOA HAC My first comment is that the approach has to be an integrated approach. We’ve heard aspects of bits and pieces. If the EAP is to work, and I believe EAPs can work, they have to be integrated within the whole of the psychological health plan. I would say to operators and contractors alike that they need to consider planning for psychological health just as much as physical health. Your EAP, if properly utilised, can be very much part of that. Certainly we’ve been working to improve access to EAP. We do have access via telephone and yes we do pay for all our Comment – Professor Josephine Arendt, University of Surrey I was just going to add to that question about lack of decision making ability cognitive impairment over here. Without wanting to labour the point, there has been the recent publication that jet-lag crossing time zones rapidly induces deficits in cognitive reasoning and ability to perform, and long term 219 moreover. Now you may think that’s irrelevant but it’s not because it’s precisely the same situation for an unadapted night shift worker. Answer - Dr Ron Gardner, HSE There are various aspects to that. I might want to pull in Shirley and Alan as well because of their background to make sure I get this right. Stress per se is not reportable. There is no mechanism for reporting it except as I recall in parts of RIDDOR there’s some generality to cover things you need to report, but stress as a condition isn’t reportable. It’s not included. I don’t see any simple mechanism for saying yes, you report it. Accidents are the only ones where you need to have a three-day limit. All the other illnesses and diseases if you’ve got them, if they are reportable, they are reported. It doesn’t depend on the amount of time you have off. It just happens that stress per se is not defined. Comment - Dr Valerie Sutherland, Sutherland-Bradley Associates Could I just say that I think if people were trained and educated to understand the stress process, not just to be told it’s going to make them feel irritable or have a dry mouth, but why they feel like that. As Jo says, we know that if you are under stress you do have cognitive impairment that will affect your reaction times. If they can know that they are going to be impaired in these ways and they are going to have the physiological and emotional reactions, then they are a little bit more prepared for it, without blaming them for something that they can’t cope with, that it is a normal response and if they can recognise it. It’s the sort of training you would expect bomb disposal experts to have. If they’re crouched over the bomb I should imagine their stress levels are very high but they are just trained to override those because they know that’s what’s going to happen to their body. They are human beings. They’re not robots. Comment - Steve Taylor, Shell Expro The very point of this conference is getting off the back foot, which is lagging indicators if you like, such as accidents, and getting on the front foot - occupational health - stopping accidents before we have them. My point would be perhaps we need to look at this again because, as the lady said up there, stress is an accident waiting to happen. Comment – Dr Ron Gardner, HSE I couldn’t agree more but your original question was about what the regulations currently say. One of the points that was made early on in the conference was that under Securing Health Together one of the programmes is entitled ‘Compliance’ and part of that is looking at whether our regulations are fit for purpose, whether they need changing. Maybe this is one area where we do need some changes. The other point I would make, Jim Keech spoke earlier as well about the work that Step Change is setting up in terms of collecting medic consultation data, time off data, things like that and maybe again this is a mechanism for picking up this sort of incident. Comment - Jake Molloy, OILC Offshore Union All the speakers have touched on, and indeed the video touched on, the issue of selfconfidence, which in itself brings about this feeling of empowerment. I think an observation sitting on the workforce side of the fence is that that is severely lacking. If you can address the self confidence and empowerment issue, then it may assist in reducing stress, incidents, accidents etc. One typical example:- if the workforce were empowered I’m quite sure that we would see an immediate reduction in working hours offshore and address a lot of the problems that we were talking about here this morning. Answer – Dr Jim Keech, BP, Chairman of UKOOA HAC Just to answer some of the points. The regulator doesn’t help. RIDDOR certainly doesn’t help. It’s not their fault. Most of the operators here are already recording these events and certainly I can speak very definitely for BP that we do record psychological illness as an occupational illness. It is reported as a ‘day away from work case’ and we are aware of it and do report it and try and manage it. To go on on Ron’s point, we intend certainly in Step Change as we find this way forward with the health database, to look at psychological Question - Steve Taylor, Shell Expro Your comments, Mr Chairman, on the question that’s not been answered at the moment. You said about the opinion of people actually classifying stress or people off with stress as an LTI. Well I guess there are the regulators in the room secreted amongst us at the moment. I’d like to hear what their view is on that because to my knowledge everything that we have is either medical, the guy’s injured, he’s off as an LTI, or he’s off for medical reasons which doesn’t appear. An opinion please. 220 predominant factor there. I wonder if the psychologists have got any comment to make about the use of the word ‘pressure’ as being a good thing in the individual? I think that to most people pressure has got a bit of a prejorative spin to it. health issues. I’ve recently had a report. We’ve got nine thousand encounters now classified in the last two years in BP. We have included psychological health classification in there and this is very much the sort of thing we would want to do with a cross industry database. I think what it has shown me, and what I’ve been able to use when presenting to management, is the psychological ill-health load as represented by the work that the offshore medics are doing. It doesn’t necessarily cause an accident, it doesn’t necessarily cause anybody to go off sick but it is captured there in the encounter. Certainly on some installations we have classified a third of the workload on encounters as being due to psychosocial encounters. Answer – Ronny Lardner, Keil Centre My comment would be that I think there is a lot of confusion about these terms and you’ve got to come to a decision about the best ones to use and use them consistently. I notice that the HSE’s definition of stress in their publicity is that there is no such thing as good stress. You often hear people say well a bit of stress is good for you. I don’t think that’s a helpful message to use because people can use that ill advisedly. I certainly feel that the message that there is no such thing as good stress, but pressure is a positive thing is a consistent message. I think perhaps what you’re referring to is that many people would say when pressure becomes excessive it is a problem. That’s when it becomes stress. Question - James Johnson, Shell We, like BP, record sickness absence from psychological problems as well, and we also include contractor staff as well as operator staff. We’re faced always with the problem mentioned earlier of trying to tease out the personal or domestic component from the purely occupational one and we really have to get around and decide which is the more 221 222 DAY 3 AFTERNOON SESSION SESSION THEME – WELLBEING AND FITNESS FOR DUTY 223 224 HEALTH CARE AND FIRST AID ON OFFSHORE INSTALLATIONS - THE REVISED ACOP Alan Morley, Safety Policy Directorate, HSE Continuing to specify minimum provision levels for people, equipment and facilities does not fit in with making an individual assessment of needs. So these lists were dropped in favour of a new appendix, which sets out factors that duty holders need to consider when making their assessments. Factors like: - how many people are normally on board, - the types of activity taking place, - likely weather conditions, - and proper storage, supervision and security for prescription only drugs. I worked on production of the revised Approved Code of Practice on the Offshore First Aid Regulations. I shall outline for you some of the main changes that were made and explain why we made them. The revised ACoP comes into force on 2 April 2001. And on that day the old one ceases to have effect. You can buy copies of the revised ACoP from HSE Books and other good book sellers. The price is £6.00. Revision of the ACoP followed the Health and Safety Commission’s review of all health and safety regulations and ACoPs. The Commission found the offshore first aid regulations were properly goal setting, but that the ACoP was too prescriptive. As a result, in 1998, it published a Consultative Document proposing changes to the ACoP (but not the regulations) and inviting comments. I’d like to thank everyone who responded. We took careful note of all of the comments we received, where possible making alterations to what had been proposed. It became a lengthy process. Health care and first aid is a subject about which people have strong views. It led to a further round of informal consultation before the revised ACoP could be finalised. Lets now look at the medical equipment list. A number of respondents asked for the lists of equipment and facilities in the old ACoP to be retained. Their continued publication by HSC would have been against the Commission’s policy of moving to a goal based regime. But they still have value, for example, as a means of reference. UKOOA have therefore taken them over and published updated lists. They are called Guidelines for First aid on Medical Equipment on Offshore Installations and copies are available from UKOOA. So far as the role and responsibilities of an offshore medic are concerned, we have added guidance as an Appendix. It includes advice on what are and are not suitable secondary roles for offshore medics. Suitable ones may well include: - helping prepare the assessment of needs for an installation, - making health-based risk assessments, - and basic first-aid training. But not roles that could be conflicting, for example, helicopter landing officer - you should not plan to have one person in two places at once during an emergency. There were a number of reasons that we couldn’t take everything into account. These include: - legal reasons, - the extent of HSE’s remit, - some respondents gave opposing views or their suggestions were not workable. There are five main changes. The first is about assessing needs. The revised ACoP brings the provision of offshore health care and first aid into line with modern legislation. For health care and first aid, duty holders will now determine what people, equipment and facilities are required through an assessment of needs. So that, in future, duty holders will establish the requirements for their own particular installation, rather than mostly relying on lists in the old ACoP. More prominence has been given to health care. As already indicated, the name of the ACoP has changed to ‘Health care and first aid on offshore installations and pipeline works’. Thus adding ‘health care’. This follows concerns raised by a number of people, that health care should clearly be a part of the ACoP, and not take second place to first aid. In spite of their titles, the regulations and ACoP have always dealt with both health care and 225 onshore. Copies are available from HSE Books. first aid. But in re-writing the ACoP we have tried to make the place of health care clearer. So, as well as the title, for example, the Appendix on the roles and responsibilities of offshore medics clearly includes health care. To sum up, we believe that this revised ACoP will allow duty holders much greater flexibility to assess their own health care and first aid needs. In future, you will tailor what is provided to suit your individual offshore location, instead of a standard package which is less fitted to the needs of that place. In other words - as a duty holder, you decide what you need and you provide it. This revised ACoP is relevant to everyone in promoting health care and well being offshore. Finally, we have revised some of the training arrangements. In particular trainers no longer have to have experience of working offshore. This will only directly affect the training organisations. The old ACoP gave no indication about what the experience should be. We concluded an understanding could - for the purposes of first aid and health care - be obtained in other ways. The most important factor is for people to be used who are good trainers. This should ultimately be of benefit to everyone. QUESTIONS AND ANSWERS SESSION (NB – The following question and answer was taken from FD’s notes as this session was not recorded on tape.) And secondly, for training, especially first aid training, the ACoP has been revised to bring it more into line with what is said in the ONSHORE first aid ACoP. For example, the list of training subjects for offshore firstaiders, has been re-written as a list of competencies. Question – Jake Malloy, OILC Offshore Union Is the ACOP enforceable? Particularly in relation to medics’ alternative roles, such as cleaning duties. In revising the ACoP, we realised that the offshore emergency first aid advice leaflet is very similar to the onshore one - ‘Basic Advice on first aid at work’. After consideration by our doctors, we decided that there is no need to have a separate offshore leaflet. So this has been replaced by the onshore one - which is now approved for use offshore, as well as Answer – Alan Morley, HSE The guidance suggests that medics should not be undertaking cleaning duties. It would be difficult for an OIM to show that a medic who was doing cleaning was immediately available for emergencies. Inspectors may challenge such a situation. 226 WELLBEING AT WORK Fiona Farmer, Regional Officer, MSF Family responsibilities Working hours Employment security Musculoskeletal Disorders Control of work Occupational health scheme The World Health Organisation defines health as “a state of complete physical, mental and social well-being and does not merely consist of an absence of disease or infirmity.” MSF is running a campaign to demonstrate the importance of well-being to the employee and the employer. Really good occupational health as expressed by well-being, can only be effective if all decisions in the organisation are subject to an OH audit. All decisions need to take account of the potential impact on well-being. Wellbeing should be seen as an holistic approach to the broadest interpretation of Occupational Health. Occupational health has improved in the past two decades but still concentrates on the physical issues where cause and effect are clearly demonstrated. The tackling of stress is still seen by too many as a “difficult” area, let alone some of the “softer” areas such a wellbeing which incorporate social and family factors into the equation. To be effective these issues have to be addressed by a partnership between employers and employees, which has to be reflected at all levels in the organisation. Thus occupational health should not be seen as something which is “done” to or for employees but something of which they take joint control. Workers well-being will be high if employers provide a good response to the issues of: Workplace hazards Dignity at work Equal opportunities 227 228 THE MEDICAL AND PHYSICAL FITNESS OF OFFSHORE EMERGENCY RESPONSE RESCUE TEAM MEMBERS Dr Allan C Prentice, Aon Occupational Health Abstract Introduction Objective – To determine whether the selection process for fire-team duties in the offshore oil industry takes sufficient account of the medical and physical status of the personnel selected. My interest in the issue of medical and physical fitness for fire-team duties in the offshore environment commenced many years ago following an enquiry from an employer when an employee had been refused entry onto a fire-team course. The employee had assumed that since the employee had already passed a medical assessment for offshore work that he would be fit for this additional role. Further to this I identified more cases where fitness for fire-team duties was an issue. These were mostly problems with the loco-motor system, respiratory problems, visual defects and cardio-respiratory fitness problems. Methods – The medical selection criteria for fire-fighters onshore were identified, with a literature review to determine their basis, and the relevance of the physiological performance tests to fire-fighting. These were contrasted with the guidelines for offshore work. A physical fitness assessment, comparable to that used for fire-fighters, was performed on offshore fire-team members following the completion of a fitness questionnaire. Their occupational health records were then reviewed to determine whether there were any issues relevant to fire-fighting. Fitness for fire-team duties can be regarded as a health and safety issue where it would be appropriate to assess an individual’s suitability rather than leaving the identification of any potential problems to chance. Main findings - 73 per cent of subjects in the study group (n = 48) had a satisfactory cardiorespiratory fitness for effective fire-fighting (VO2 max ≥ 45 ml/kg/min). A further 23 per cent had an equivocal aerobic fitness (VO2 max ≥ 40 ml/kg/min, < 45 ml/kg/min). Only 4 per cent found with poor cardio-respiratory fitness for fire-fighting (VO2 max < 40ml/kg/min). Fitness for fire-fighting onshore is governed by legislative standards. The Fire Service (Appointments and Provisions) Amendment Regulations 1988 and The Fire Service (Appointments and Provisions) Regulations 1978. What are these standards and would they be appropriate? The amendments were based on the work of Scott (Scott, 1987) and are essentially physical fitness standards. 75 per cent had sufficient lower body strength, when compared to the desired level (leg/back pull ≥ 139 kg). All but one had a leg/back pull score within the current guidelines for fire-fighting (≥ 117kg). All subjects had satisfactory upper body strength (grip strength ≥ 35 kg) when compared to the fire-fighting standard. All grip strengths were also above the desired level (≥ 40 kg). Two subjects fell out with the visual acuity standards for firefighting (6/60, N48 (uncorrected), 6/9-4, N12 (corrected). This research identified that a low physical fitness capability existed in serving firefighters. Only 14 per cent were of normal weight, with 27 per cent mildly overweight and the remaining 59 per cent either obese or excessively obese. In addition the fire-fighters as a group possessed only average aerobic fitness, with nearly 25 per cent having a maximum aerobic capacity (VO2 max) where they would be unduly fatigued when undertaking some drills and calls (Brown et al, 1982; Lemon and Hermiston, 1977; Horowitz and Montgomery, 1993; Saupe et al, 1991). Also reported was an increasing percentage of low physiological test scores in older groups indicating that fire-fighters were not able to maintain their fitness as they aged. Conclusion – An additional assessment to that required for offshore work is needed for fireteam members. This should include a detailed evaluation of musculo-skeletal and cardiorespiratory fitness. Recommendations for this assessment have been made, which includes physiological testing. 229 will also affect the cardiovascular response to exercise. The normal thermo-regulatory response is compromised, as sweat will not be able to evaporate. The increase in core body temperature, which cannot be dissipated, leads to a further reduction in peripheral resistance and to an increase in peripheral circulation. Venous return is reduced and with this ventricular filling. The reduced stroke volume leads to a compensatory increase in heart rate to maintain cardiac output, thereby creating more cardiac strain. In extreme situations where cardiac output cannot be maintained collapse will occur. Other studies in the UK and abroad have identified similar findings. This decline has been reported, in part to be caused by the increasing prevalence of medical conditions with ageing. Lifestyle factors may also contribute to this change (Freil et al, 1988) and specific fitness training programmes have been recommended together with health education to mitigate against this effect. (Shephard, 1991; Posner et al, 1986). Fitness for fire-fighting Cardiovascular Fitness Several studies have demonstrated the cardiovascular strain imposed by fire-fighting in the emergency situation (Barnard and Duncan, 1975; Sothman et al, 1992; Douglas et al, 1988). It is also recognised that those fire-fighters, with lower cardiovascular fitness, performing at lower work rates, will take longer to complete any physically strenuous work tasks (Manning and Griggs, 1983; Sothman et al, 1990; Sothman et al, 1991). This can have serious implications to the individual fire-fighter, his colleagues and others, where the success of an operation can be defined in terms of lives saved and in the minimisation of structural or property damage. In order to avoid fatigue in an individual, aerobic work lasting longer than one hour should only be sustained at a level, which is approximately equal to 50 per cent of their VO2 max. A more intense work rate can be sustained for a shorter period and work at 85 per cent VO2 max can be performed for periods of up to 10 minutes. Employment discrimination law in North America has focused attention on job specific functional fitness requirements, and with firefighting this has been determined following analysis of the energy costs of key tasks. This has then been used to determine a level of aerobic capacity considered appropriate. Gledhill and Jamnik (1992) studied the most demanding fire-fighting operations. Ninety per cent of these required a mean oxygen consumption (VO2) of 23 ml/kg/min, but the most demanding tasks require a mean VO2 of 41.5 ml/kg/min. Based on this a minimum standard for fire-fighter applicants of 45 ml/kg/min was recommended. Sothman et al (1991) measured oxygen consumption during simulated fire-fighting tasks and concluded that a minimum VO2 max of 33.5 ml/kg/min would be necessary. However, the tasks involved were representative of a walk up or low rise fire and they then questioned whether this limit would provide sufficient reserve for effective performance under situations demanding more strenuous physical work. A VO2 of 41 ml/kg/min was the level at which all tasks were completed correctly and in a later study, it was concluded that aerobic capacity should be maintained at a level of 42 ml/kg/min or above (Douglas et al, 1988). This is the same figure that was recommended by Davis et al in 1982 as the minimum, with 49 ml/kg/min recommended to meet the requirements of the job, and to provide a sufficient margin of safety. Emergency fire fighting is a strenuous physical activity where any cardiovascular strain caused by the tasks is compounded by the conditions encountered. The effect of an increased workload caused by the weight of protective equipment and the use of positive pressure demand self contained breathing apparatus (SCBA) is well documented (Lusa et al, 1993; Sköldström, 1987; Louhevarara et al, 1995). Fire fighters have reported that work involving the use of SCBA and under conditions of extreme heat is particularly fatiguing (Lusa et al, 1994) with up to a 25 per cent increase in fatigue reported (Davis, 1982). When SCBA respiratory effort is increased due to exhalation resistance from the valve, designed to maintain positive pressure within the facemask. The respiratory dead space is also increased which has the effect of increasing alveolar carbon dioxide tension thereby increasing ventilation rate at rest and at work. However, in those with adequate respiratory function this will not have any significant implications. Pulmonary factors will not limit cardio-respiratory performance unless there is significant pulmonary disease or the exercise is being performed at altitude. The high ambient temperature and humidity that may be encountered on the fire-ground 230 applied, with the minimum acceptable aerobic capacity reducing, as shown in Table 1, from the recruitment level to 37 ml/kg/min at age 65 (Home Office, 1991). This position is somewhat controversial, since it is not possible to match the demands of any particular emergency task to the age of the fire-fighter (Haisman, 1996). In the UK the recommended minimum aerobic capacity for fire-fighter recruits is 45 ml/kg/min (Home Office, 1988). This recommendation is based on Scott’s findings where the top 75 per cent of his subjects were found to have an aerobic capacity equal to or above this level. Guidance produced subsequently recommended that for in service fire-fighters age related criteria should be Table 1 : Suggested minimum VO2 max values for serving fire-fighters Nearest Age (years) 25 30 35 40 45 50 55 60 65 VO2 max. (ml/kg/min) 45 44 43 42 41 40 39 38 37 The justification for such tests, is also based on the work of Scott. He showed that muscular strength, in contrast to the findings surrounding aerobic capacity, was effectively maintained at a suitable level by the daily duties required of a fire-fighter. Less than one per cent assessed were found with insufficient strength for the job. The JWPAP in its report used these findings to recommend minimum strength standards for fire-fighters (mean value minus two standard deviations). Using this criterion, the standards for handgrip were ≥ 40 kg dominant hand and ≥ 38 kg subordinate hand, with a leg/back pull strength of ≥ 139 kg. However, these figures were not included in the regulations as concerns were raised that they may discriminate against women firefighters and applicants indirectly, due to natural differences in physique. To accommodate for this, and to ensure that there is reasonable account taken to avoid the charge of sex discrimination, the standards were set at the 50th centile of strength for women. Muscular Fitness Good cardio-respiratory function is not the only physiological parameter necessary for effective fire-fighting. Reports from both firefighters and from job analysis studies have identified that certain key emergency tasks require a satisfactory level of muscular fitness (Lusa, 1993; Davis et al, 1982; Gledhill and Jamnik, 1992). The relevance of muscular fitness and endurance has been recognised for many years and testing was prescribed under the 1978 Fire Services’ (Appointments and Promotions) Regulations. However, the strength test prescribed was somewhat empirical. A fire-fighter was expected to be able to carry a person weighing between 63.5 76.2 kg (10 - 12 St) a distance of 91.4 km (100 yd) in a time not exceeding 60 seconds. This test was recognised as being neither sensitive nor specific and did not test upper-body strength. The 1988 Regulations introduced the concept of strength tests for different muscle groups with measurements of upper-body and lower-body strength, although it was noted that several brigades had already introduced similar testing procedures prior to this. The regulations specify that isometric strength testing should be performed. Handgrip should be tested as a measure for upper-body strength (≥ 35 kg dominant hand, ≥ 33 kg subordinate hand) with leg/back strength as the measure for the lower-body (≥ 117 kg). Respiratory Fitness The current regulations specify that lung function should be tested using standard spirometric techniques with measures of the Forced Expiratory Volume at one second (FEV1) and the Forced Vital Capacity (FVC) being prescribed. No specific limits are set, candidates being assessed on clinical grounds. Exposure to smoke and the products of pyrolysis is a recognised occupational hazard 231 to fire-fighters and was particularly common prior to the introduction of self-contained Breathing Apparatus (SCBA) as a routine measure. Acute reduction in respiratory function is well documented (Musk et al, 1979; Sheppard et al, 1986; Brandt-Rauf et al, 1989; Sherman et al, 1989; Chia et al, 1990). The chronic effect of smoke inhalation is less clear. Some have suggested an adverse effect (Guidotti and Clough, 1992; Moisan, 1991) whereas others have not (Douglas et al, 1985; Horsfield et al, 1988). Thus, the JWPAP recommendation for respiratory function was included as a specific health surveillance measure. Vision Standards Visual Acuity The visual requirements were recently reviewed by the Fireground Vision Research Unit (City University, 1995). Stringent visual acuity standards are specified on entry to fulltime work 6/6, 6/6 (Scottish Office, 1996). This reflects an intention to ensure that a firefighter’s vision will remain satisfactory throughout an operational career, anticipating the possibility of presbyopic or other changes. Subsequently, the in service standard is 6/9-4, N12 (corrected if necessary). From assessment many of the distance tasks a firefighter must perform equate to 6/9-4 and near tasks to N12. Notwithstanding this, the uncorrected visual acuity standards 6/60, N48 must be met, the minimum identified for effective safety performance should spectacles be lost. The in service standards also apply to retained fire-fighters, although the entry standard is less strict (6/9, 6/9) and can be relaxed, where recruitment difficulties exist, to the previous limit for serving fire-fighters (6/18, 6/24). Where visual correction is needed the spectacles must be compatible with the SCBA mask, as when ordinary spectacles have been used a significant reduction in cylinder discharge has been noted, implying that leakage must have occurred. Anthropometric Standards The 1988 Regulations continued with the recommendation for a minimum height of 1.68 m and introduced a maximum height limit of 1.93 m. The minimum height requirement can be traced back to the 1950 Fire Services’ (Appointments and Promotions) Regulations, when a minimum height of 170 cm (5 ft 7 in) was stipulated. This was reduced to the current limit in 1967 to enable fire authorities to recruit from a larger proportion of the population than previously (David and Hoffman, 1996). The recommendation for a minimum height requirement was initially based on the assumption of a good correlation between height and strength. Since firefighting is regarded as a team based activity, it was argued that maximum efficiency could be achieved if all team members were of near equal height. The need for a maximum height limit (1.93 m) followed, giving what was considered to be a reasonable and workable span (25 cm). It was also argued that for Fire Services to accommodate for those who were out with the specified range was impractical as the redesign of any necessary equipment was considered to be difficult due to technical constraints and, if possible, likely to be prohibitively expensive. Colour Vision The Fireground Vision Research Unit also reviewed the colour vision requirements. Failure to identify colour codes quickly and accurately may be extremely hazardous during a fire emergency. Commonly encountered tasks include the recognition of safety signs, pipelines, gas cylinders (medical and industrial), portable fire extinguishers and lines which may be used to power various pieces of fire-fighting equipment. Historically, only individuals with perfect colour vision were recruited to the Fire Service, but the standards now permit those with a slight impairment of green perception (deuteranomalous trichromatism) to be considered fit for firefighting. It was shown that those with this as a mild impairment do not compromise safety. In contrast, those with defective red discrimination (protanomalous trichromatism) are a safety hazard. They are also unable to differentiate numerous industrial gas cylinders such as propane and methyl chloride, argon and oxygen, and acetylene and oxygen. They are unable to distinguish colours used to code the contents of pipelines, as are severe deuteranomalopes. Protanomalopes may also David and Hoffman did not consider these arguments to be valid. Height was not considered to be a useful selection tool, as height does not correlate well with strength. Also, any difficulties in team handling of loads can usually be accommodated for with the appropriate positioning of those individuals of unequal heights. It has also been possible to design improved equipment storage systems on Fire Service vehicles. Therefore, they concluded that the retention of the height limits could not be justified. 232 confuse oxygen (black) (maroon) cylinders. and such additional guidance for fire-fighting at present. However, the guidelines do include general guidance that a medical examiner, in the assessment, needs to take account of the work environment, and that individuals are required to be physically fit for their employment. This includes the ability to react effectively to an emergency situation. Although individuals are required to be physically fit no physical performance tests or standards are recommended, except for lung function. A peak flow measurement is recommended to be part of each initial assessment. Further spirometry is not essential although the guidelines stipulate that, where FVC is below 70 percent or FEV1 below 65 per cent of predicted values, this would indicate a significant disability. acetylene Medical Standards No national medical standards for fire-fighting exist at present. A medical examination is required on entry and recommended threeyearly thereafter, but the Fire Service Regulations only state that the medical examiner must be satisfied that a candidate is able to perform fire-fighting duties. In its report, the JWPAP did comment on certain specific medical conditions and made a recommendation that Fire Service Medical Advisers should establish a forum to meet and formulate common medical standards, policies and practice. Comprehensive medical guidelines are currently being prepared by the Association of Local Authority Medical Advisors (ALAMA), which should form the basis of nationally recognised minimum standards (Davies, 1997). In contrast to the offshore guidelines the firefighting standards provide general guidance about the medical history and examination findings, The current standards are essentially based on the results from the physiological tests, with additional account being taken of any medical conditions. This situation is therefore, almost the reverse to that required for offshore work. In making their recommendations for specific medical conditions, the JWPAP obtained guidance from the Faculty of Occupational Medicine. Conditions such as insulindependant diabetes and epilepsy, where sudden collapse is a possibility, were considered to be a bar to fire-fighting. Other conditions noted by the JWPAP to require special consideration include disorders of the skin, musculo-skeletal system, cardiovascular disease and hearing. Back and knee conditions are a leading cause of disability reported in fire-fighters (Lusa et al, 1993). The cardiovascular strain imposed by fire-fighting has been discussed above. No comment was made specifically about respiratory disease, although as mentioned above lung function tests are recommended as a health surveillance measure. The UKOOA medical guidelines and the Medical Standards for fire-fighters are contrasted in Table 2. Contrast Between the Offshore Medical Guidelines and Standards for Fire-fighting Fire-fighting offshore is performed as an additional function to the employee’s main task and the examination to determine fitness for offshore work does not assess fitness for fire-fighting specifically. The UKOOA medical guidelines include comprehensive guidance about the history and examination findings for each body system, indicating which conditions would not be acceptable for work in this environment. For the most part the guidance is generic and not specific to any group or occupation, although appendices to the document offer additional guidance where particular issues have been identified e.g. catering crew and crane operators. There is no 233 Table 2 : Contrast between Fire-fighting Standards and UKOOA Guidelines Systems Review Fire-fighting Standard General guidance only (specific guidance developed) being UKOOA Guidelines Specific guidance for each system indicating what is acceptable / unacceptable Height 1.68m to 1.93m None specified Weight None specified None specified BMI None specified > 35 kg/m2 generally unacceptable Visual Acuity (distance) 6/9-4 (corrected), 6/60 (uncorrected) when in service with higher standards at recruitment 6/12 (corrected) in better eye.

However, whether this means that they need to meet the onshore fire-fighting standard could be questioned, as this is a secondary function to their main occupation. This argument has also been used with parttime retained fire-fighters onshore, but has been discounted. When in the fire-fighting situation they face the same hazards and must perform the same tasks as full-time firefighters, possibly at the same fire scene. Such tasks are assessed as critical to safety and effective performance, so the same medical and fitness standards should apply. The situation offshore is comparable, where in addition, the fire-team member may be exposed to some of the most extreme conditions that could be encountered in firefighting. These include high ambient temperatures in humid conditions, fighting industrial type fires in confined spaces, and where withdrawal from the fire scene may be restricted (Bennet et al, 1995). The structure of an offshore installation also means that access to the fire scene may involve a significant level of exertion (O’Connell et al, 1986). Therefore, 234 height. This height is recommended for those used to a moderate degree of vigorous exertion to ensure that the heart rate is elevated to 80 percent of the age related maximum (Sykes, 1995). The stepping rate was controlled from a tape recorded metronome. Heart rate was monitored throughout the test using a Polar heart rate monitor. The Chester Step Test is a multistaged procedure, where the staged increase in work-rate is controlled through an incrementally increasing step rate. Each stage lasts for two minutes and heart rate is measured at the end. This is to ensure that a steady heart rate has been reached thereby increasing prediction accuracy. The subject’s results were plotted on the set chart from which the predicted maximum aerobic capacity (VO2 max) was then read. it is entirely appropriate that such fitness standards or a similar equivalent should be applied. Offshore Emergency Response Rescue Team Medical And Physical Fitness Study Objective and Setting The objective of the study was to determine whether the current selection process for offshore emergency response rescue team (fire-team) duties takes sufficient account of the medical and physical status of the personnel selected. The study was based on the workforce from an Operator with platforms in the North Sea. The fire-teams consist of both operator and contractor personnel. Methods Fire-team members were identified from company records and sent letters inviting them to participate in the study; there were 48 positive replies from 115. Individuals were asked to assess their own capability and proficiency using a modified Fitness of Firemen questionnaire. The Fitness of Firemen questionnaire had been developed to gain information from full time fire-fighters regarding their own perception of fitness (Goldsmith, 1995). The questions specific to full-time fire-fighting and training activities were omitted and the lengthy section on sport and leisure activities condensed. The questionnaire was then slightly altered following a test with onshore safety personnel responsible for emergency response. Isometric muscle strength was assessed using measurements of grip and leg/back strength taken with digital dynamometers (Takei Scientific Instruments). Grip strength was measured after adjusting the grip for the subject’s size. The average of 4 measurements was taken from alternating tests on left and right hands. The manufacturer’s guidelines were followed with subjects standing upright with arms extending downwards. Then, while holding the dynamometer, they were requested to exert full force without touching their body. A modified procedure was used for assessing leg/back strength because of the potential for inducing injury when following the manufacturer’s guidelines. The handle attachment was adjusted for the patient’s height and with the knees bent at 130°-140° and back straight the subject was requested to pull upwards using maximum force while breathing out. After completing the questionnaire, physiological parameters were assessed. This was done at work, in the installation health centres, by one of the offshore medics or myself. Height and weight were measured and Body Mass Index (BMI) was calculated (weight/height2). Visual acuity was measured using Snellen Charts at 6 m for distance and reading cards at 30 cm. Colour vision was assessed using the Ishihara method. Lung function was measured using standard spirometry measurements, FVC, FEV1 and FEV1%. The spirometry measurements were taken using a Micro Medical microspirometer calibrated to read at body temperature and pressure saturated with water vapour (BTPS). Occupational health records were reviewed, where these were obtainable, to determine whether there was any significant condition documented liable to affect fitness for firefighting. Particular emphasis was placed on any cardio-respiratory or musculo-skeletal problems because of the perceived increased demands on such systems, which would be employed in fire-fighting duties in contrast to general offshore work. Statistical Analysis The records were collated on computer using the Microsoft Access database and analysed using the Excel spreadsheet and Analysis Toolpak. Where relevant, parameters were compared to the statutory fire-fighting standard. This included the visual requirements, aerobic capacity and musculo- Volunteers then underwent tests of aerobic capacity and isometric muscle strength. Maximum aerobic capacity (VO2 max) was measured indirectly from a sub-maximal exercise step following the Chester Step Test protocol at the 30 cm (12 inch) stepping 235 allocated a numerical equivalent, as outlined below in Table 3. skeletal measurements. Correlation analysis was then performed on the anthropometric data, lung function and physical fitness tests. Aerobic capacity and musculo-skeletal strength were grouped according to the firefighting standard, and in the case of the leg/back strength, also to the standards originally recommended by the JWPAP. Smoking was categorised dependant upon whether the subject was a cigarette smoker (4), pipe/cigar smoker (3), ex-smoker (2), or nonsmoker (1). Alcohol intake was converted into equivalent dosage in units/week using the standard conversion formula (glass wine/measure of spirit/half-pint beer = 1 unit).

Jogging or running, weight training, racquet and winter sports were mentioned less frequently. Those who did not exercise reported that this was either because they were not interested or due to lack of time. Fitness Self Assessment In general, most subjects believed that they were of average or above average physical fitness levels. All felt that they were fit enough to perform both their regular work and fire team duties. Smoking and Alcohol Smoking was not a common activity with less than 20 per cent of the study group being current smokers and with over 50 percent never having smoked. Estimated alcohol consumption showed that over half drank within the recommended safe limit (≤ 21units/week) but 23 per cent had an estimated alcohol consumption in the hazardous range (≥ 35 units/week). Weight and Diet Fifty-six per cent thought they were in the normal weight range with 42 per cent believing they were either slightly overweight or overweight. However, when asked to estimate their height and weight, 29 per cent were in the desired range for weight, 63 per cent were overweight and 6 per cent obese. One individual’s estimate gave him a body mass index ≥ 40. This individual was not overweight and there may have been some confusion between imperial and metric values. The measured BMI showed slightly more within the normal range (40 per cent) and correspondingly less in the overweight range (54 per cent). Injuries and Illnesses Most reported no time off through injury or illness. One subject reported 35 days off following a knee arthroscopy, and one 40 days off with septicaemia. One had undergone cataract surgery and required 10 days off. The rest with less than 14 days absence declared cold or flu symptoms, or musculoskeletal complaints. Two of those with musculoskeletal complaints stated that it restricted their activities. One had a back strain requiring 10 days off and the other 4 days absence due to a neck complaint. Another subject declared a shoulder muscle injury restricting his activities but had not required any time off. No one reported an injury due to lack of fitness Twenty-five per cent of the study group as a whole claimed that they made a special effort to diet, split fairly evenly between those who considered that their weight was normal and the overweight group. Although they all felt that they were fit enough to do the job, 35 per cent in the overweight group felt that they could do the job better if they weighed less. This compares with 19 per cent in the normal weight group a difference which is not statistically significant (P > 0.05, Chi squared test). Correlation Analysis Tables 10, 11 and 12 show the Spearman’s ranked correlation coefficients (rs) for age and anthropometry measurements, lung function tests and the physical fitness tests against other variables. For sample size n = 48, if rs ≥ 0.285 then P < 0.05). Physical Activity The majority undertook some form of physical activity during their leisure time, more than two-thirds doing this on a weekly basis, or more frequently. This was usually at a moderate, hard or fairly hard intensity. The most popular forms of exercise mentioned were cycling, golf, walking or hill-walking, swimming and gym workouts (cardiovascular 240 Table 10: Correlation matrix for age and anthropometry Age Height 0.137 Measured Weight 0.128 BMI 0.084 0.09 0.095 0.067 0.823 0.507 0.189 0.742 0.775 0.619 0.482 0.725 0.73 -0.006 0.266 -0.064 -0.03 -0.174 0.135 -0.19 0.197 0.085 -0.145 -0.25 -0.235 Alcohol Intake 0.013 -0.015 -0.012 -0.007 Smoking Score -0.179 -0.347 -0.193 -0.01 Exercise Type Amount Level 0.206 0.228 0.144 0.1 0.314 0.121 0.025 0.279 0.017 -0.007 0.192 -0.043 Age Self Assessed Height Weight BMI Fitness Rating Stamina Muscular Strength General Fitness Table 11 : Correlation matrix for lung function FEV1 FVC FEV1% Age Measured Height Weight BMI -0.22 -0.133 -0.213 0.596 0.394 0.122 0.702 0.451 0.139 -0.268 -0.095 0.036 Alcohol Intake -0.11 -0.076 -0.123 Smoking Score -0.08 -0.152 0.217 0.117 0.006 0.063 0.041 0.154 -0.073 0.042 0.075 -0.071 0.091 0.288 0.11 0.102 0.268 0.165 -0.078 0.112 -0.149 Fitness Rating Stamina Muscular Strength General Fitness Exercise Type Amount Level 241 Table 12: Correlation matrix for physical fitness Aerobic Capacity -0.348 Leg/back Strength 0.101 Grip Strength 0.041 0.057 -0.158 -0.243 0.318 0.428 0.39 0.225 0.425 0.401 Lung Function FEV1 FVC FEV1% 0.385 0.343 0.05 0.249 0.266 0.002 0.355 0.346 0.006 Alcohol Intake -0.224 -0.385 -0.068 Smoking Status 0.067 0.041 0.146 Leg/Back Strength 0.064 Grip Strength 0.027 0.26 Fitness Rating Muscular Strength Stamina General Fitness -0.119 0.301 0.269 0.308 0.238 0.114 0.174 -0.086 -0.084 Exercise Amount Type Level -0.061 -0.032 0.061 0.269 0.103 0.093 0.025 0.064 -0.001 Age Measured Height Weight BMI Spearman’s correlation coefficient Levels of significance (α2) (n=48) Lung Function As would have been expected, a significant correlation was noted between height and both FEV1 and FVC.

A significant positive correlation was also noted between height and exercise amount and a significant negative correlation between height and smoking score. There was also a significant negative correlation between height and smoking score. Physical Fitness Tests Aerobic capacity showed a significant positive correlation with FEV1, FVC and stamina with stamina, from the questionnaire survey. A negative correlation was noted between aerobic capacity and age. A negative correlation was also noted between aerobic capacity and both alcohol intake and BMI, although these did not reach significance. Similarly, a negative correlation was noted 242 muscular strength. Grip strength did correlate with BMI and FEV1 and FVC. There was no significant correlation between leg/back strength or grip strength and age. between leg/back strength and alcohol intake, which was significant. A significant positive correlation was found between leg/back strength and BMI and between leg/back strength and muscular strength, from the questionnaire survey. This is in contrast to the findings when grip strength was compared to Comparison with Onshore Fire-fighting Standards Table 13 lists the number of subjects who did not meet the equivalent onshore fire-fighting standard for vision and fitness tests.

The error of the test method (10 per cent) means that those between 40 and 44 ml/kg/min from this indirect test method may well have an aerobic capacity of 45 ml/kg/min or greater were direct testing to be employed. 25 per cent did not meet the originally recommended leg/back strength limit (≥ 139 kg), but only one candidate failed to reach the current standard (≥ 117 kg). All grip strengths measured were satisfactory (≥ 35 kg) indeed all met the originally recommended standard (≥ 40kg). Vision The visual standards for acuity refer to the in service requirements for part-time fire-fighters. Two subjects were found to be out with the standards. One fell below the uncorrected standard, although his corrected visual acuity was satisfactory. The second subject presented wearing contact lenses. His corrected visual acuity was normal, but the prescription strength, which he quoted, was out with the standard. If the recruitment visual acuity standard (6/9, 6/9) were applied, a further 10 would be out with the requirements, although one of these would pass the relaxed standard (6/18, 6/24). Anthropometry No one in the study group fell out with the height limits for fire-fighting. Only one subject was found to be colour blind on Ishihara plate testing, a deuteranomalous defect. The severity of the defect was not known, although the subject had volunteered that it was severe. Inter-Group Analysis Table 14 compares those who met the recommended aerobic capacity standard (≥ 45 ml/kg/min) with those who did not. For sample sizes n1 = 13 and n2 = 35 using the two tailed test, a U value of 313 or greater is considered significant (P < 0.05). Physical Fitness The majority met the aerobic capacity guidelines, although a substantial minority (27 per cent) fell below 45 ml/kg/min. The number below the standard was reduced to 8 Table 15 compares those who met the originally recommended leg/back strength 243 standard ( ≥ 139 kg) with those who did not. Where n1 = 12 and n2 = 36, a U value of 299 or greater is considered significant (P < 0.05).

They also undertook more exercise and from the questionnaire had declared greater muscular strength. These differences did not reach significance, which may be due to the small sample size, as the U values for weight, FEV1, muscular strength and exercise amount fell just below the level of significance. Aerobic Capacity Those who did not meet the standard, ≥ 45 ml/kg/min, were significantly heavier than those who did. They also tended to be older, although this difference did not reach significance. Leg/Back Strength A significant difference was noted in alcohol intake between the two groups. Those who did not meet the recommended level (≥ 139 kg) drank more than those who did. Other differences were noted, those with a leg/back Review of Occupational Health Records The review of medical records was restricted to those members of the study team who were 245 ml/kg/min. Likewise, only 4 subjects fell below the aerobic capacity standard when the age related allowance was applied. None of these were out with 10 per cent of that standard. However, the application of the agerelated standard is controversial, as the physical demands of fire-fighting cannot be tailored to suit the age of fire-fighters attending an incident Gledhill and Jamnik, 1992; de Vries, 1982. employees of the Operator. Their occupational health records are held at Liberty Occupational Health and consist principally of preemployment and periodic medical examinations. This accounted for 28 (58 per cent) of the total study group. The review concentrated on current or recent problems (those within the previous 5 years). Ten subjects were found who had recognised musculoskeletal disorders, 5 back problems, 3 knee problems, one ankle injury and a shoulder condition. Two of those declaring knee problems had undergone arthroscopy in the past 2 years. No respiratory disorders or cardiovascular disorders were noted, although one individual had undergone investigation for an ECG abnormality, finally identified as a false positive test for ischaemia. One case of vestibular disorder was reported and one subject had recently undergone cataract surgery. Age In general, aerobic capacity is recognised to decrease with age (Freil, 1988; Ilmarinen, 1991) and demonstrated in this study with the negative correlation. This reduction is primarily thought to be due to the diminished efficiency of both the circulatory system to deliver oxygen to the tissues and for this oxygen to be utilised by the tissues (de Vries, 1982). There is considerable inter-individual variation in this effect as well trained older men have been shown to be able to maintain their aerobic fitness at high levels. The negative correlation noted between aerobic capacity and age did not reach significance. This may, of course, have been due to the small sample size as an age related decrease in aerobic fitness has been a concern expressed by a number of previous studies involving firefighters (Scott, 1987; Saupe et al, 1991; Kilbom, 1980; Freil et al, 1988). It could also be that the physical characteristics of offshore installations impose certain physical attributes within the workforce. The structure of an offshore installation means that any worker involved in plant maintenance or production can spend a considerable time ascending the numerous stairs on the installation. Such incidental work effort may go some way to explaining the findings from this study. Thirdly, the voluntary nature of participation in the study may have encouraged only fit fireteam members to present themselves. Discussion Certain limitations to the study should be recognised. The sample size was relatively small with recruitment being voluntary. Also, those who volunteered may have been influenced through knowledge of the parameters being tested, with those who did not consider themselves fit declining to volunteer. However, the median age of the study group, 41 (33.5 to 50) compares favourably with the median age of the fireteam as a whole, 42 (37 to 47) and can be considered representative from this aspect. It also compares favourably with the platforms’ offshore workforce, 40 (33 to 46). Limitations in the study method, in particular, the predicted accuracy of the indirect assessment of aerobic capacity and the accuracy of the dynamometry measurements, as mentioned above, also have to be recognised. However, despite its limitations, there are several points worthy of note from the study, which are discussed below. Age limits for operational fire-fighting duties are applied in the UK and other countries. The UK limit is 55 years, although this does not extend to retained fire-fighters. In North America employment discrimination law against ageing provoked a lot of interest and debate on the subject, and whether firefighting could be a bona fide occupational qualification necessitating exception from this ruling. It was considered that it could not, hence the rationale behind the current occupational related standards, which have been recommended. Aerobic Fitness The aerobic fitness and muscular fitness measured of the fire-team members was generally satisfactory. Even those who did not meet the equivalent onshore fire-fighter aerobic fitness standard were generally above 40 ml/kg/min, equivalent to 10 per cent below the standard. This figure cannot be considered to be significantly different from 45 ml/kg/min when the error in the test method is considered. Only 2 results were below 40 246 fire-fighters to be aware of the need to maintain fitness including body weight. This was demonstrated in the study where no correlation between age and BMI shown was shown. This is in contrast to reports concerning onshore fire-fighters weight and BMI has been noted to increase with age (Scott, 1987; Brown et al, 1982; Lemon and Hermiston, 1977). The conditions and climate on offshore production facilities are much different from those which were described by Light and Gibson when they recorded an increasing prevalence of obesity with ageing (Light and Gibson, 1986). The environment is now more conducive to encourage effective maintenance of body weight. Fitness for employment and age is important generally due to the changing demographic characteristics of the workforce (Posner et al, 1986; Lancet, 1993). Advancing age is not a matter, which can be dismissed, and this is particularly relevant to the offshore oil industry as it matures along with the workforce. The economics of the business and advances in technology means that the production plant and support functions operate with fewer personnel than that which was commonly found during the industry’s inception in this country 15 - 20 years ago. The surviving workforce has been bolstered by new, younger recruits, where necessary, but overall the workforce is ageing and with this general medical and physical fitness will reduce. There is no longer a large additional pool of personnel which can be drawn from so where there are employment fitness concerns for additional duties such as fire-fighting the solution to such problems has to be obtained from the resources available. This may include additional incentives for fire-team members to maintain fitness through advancing age, with a greater emphasis in selecting those with the appropriate physical attributes for such duties, and training initiatives to ensure that those selected for such duties do retain sufficient capacity (Brown et al, 1982). Increasing age and decreasing fitness need not necessarily coincide. Chronological age can be a relatively poor indicator of both medical and physical fitness in an individual. It has been noted that the best preserved 65 year old worker has a greater functional capacity than a poorly endowed person of 25 30 years of age (Shephard, 1995) and been argued that those who chose a healthy lifestyle should not be punished for the sins of those who do not (Sharkey, 1986). Muscular Strength Unlike aerobic capacity, musculoskeletal strength test results did not decrease with age in this study, another physiological feature that has been demonstrated with onshore firefighters. The same has been noted with other occupations, which require physical effort (Nygård, 1991). Those who were heavier and had a higher BMI scored better in the strength tests. There was also a strong correlation between exercise amount and weight. An increased muscle mass, in these individuals, may account for some of this difference. Self Assessment of Fitness The significant positive correlation found between both stamina and aerobic capacity, and muscular strength and leg/back strength suggests that individuals already had a good impression of their own level of fitness. A similar finding has been noted in the past with both onshore fire-fighters (Ellam, 1994) and others (Leon et al, 1981) where it has been concluded that substantial prediction of physical fitness and work capacity can be obtained relatively easily through such techniques. Obesity In addition to age, other characteristics which may determine aerobic capacity include genetic endowment and factors which may be influenced by lifestyle such as the degree of physical training and relative body weight. This study showed that those in the lower aerobic capacity group were heavier and had a higher BMI, this difference being significant. Lifestyle Factors The low leg/back strength group had significantly higher alcohol consumption. This could be taken as an indicator of lifestyle differences. Exercise profile did not show any significant difference, although in general those in the high leg/back strength group did tend to exercise more than those in the low strength group. This difference was just below the level of significance and again possibly in a larger study group with greater statistical power the difference may have been significant. Obesity, with its increasing prevalence, is recognised as a major public health issue (Ashwell, 1994; Björntorp, 1997) and in firefighting is noted to limit performance. It has been argued that obesity has a more deleterious effect than age when assessing aerobic capacity (Schonfeld, 1990). This emphasises the need for both full and part time 247 specifications for offshore work and guidelines for fire-fighting are similar, fire-fighting does impose specific demands above that required for offshore work in general. Closer review of those required to perform such duties offshore is therefore warranted. I have been involved in several such cases, mostly surrounding musculoskeletal problems, but also others including a case of respiratory airways dysfunction syndrome (RADS). Individuals may present when they are experiencing difficulties, but this would not necessarily always be the case. Therefore, a more formal system of medical assessment for fire-team duties is required. Such a system should include a physical fitness assessment similar to that required for onshore fire-fighters. No difference in smoking status between the high and low aerobic capacity group was noted. This may have been due to the relatively small number of smokers in the group, or the effect of other variables. Tobacco smoke is known to contain up to 4 per cent by volume of carbon monoxide and a level of carboxyhaemoglobin greater than 5 per cent (reached from inhalation more than 10 - 12 cigarettes per day) has been noted to reduce aerobic capacity and performance (Horvath, 1975). Vision The revised visual standards for fire-fighters take due account of the functional needs of the task. The main difference from the previous standard is that allowance for visual correction can now be given. Two subjects fell out with the uncorrected standard, although both had satisfactory corrected vision. One wore contact lenses, not the recommended method of choice for emergency fire-fighting. However, studies have shown that contact lens wearers can perform fire-fighting tasks adequately (City University, 1995). This is particularly true for soft contact lens wearers which can be worn for prolonged periods. Such visual correction should be considered compatible with fire-team duties offshore. A number in the study group use spectacles, and for those in this category it is essential that these are compatible with SCBA. This has created logistical difficulties and added costs as the fire-team may muster at a variety of different locations, dependant on the circumstances. Therefore, there is a need to ensure that each muster station has a sufficient stock of the appropriate respiratory protection for those fire-team members who require to use spectacle inserts. Other Studies Relating to Fitness Offshore Little work has been published on the physical fitness of offshore personnel in general. Corpe studied oil industry workers based both onshore and offshore. Using the Harvard Step Test she reported a mean VO2 max of 44.4 ml/kg/min (Corpe, 1991). This ranged from 54 ml/kg/min in the 15 - 19 age group, down to 38.5 ml/kg/min in the 50 - 59 age group. In a study of North Sea divers Thompson et al (1984) reported a maximum aerobic capacity of 46 ml/kg/min and questioned whether this would give them sufficient cardio-respiratory reserve. Cotes and Reed reported comparable findings who suggested that as diving involved many sedentary and static tasks, this would not promote cardiovascular fitness. They also suggested that the greater experience of older men may offset their lower aerobic capacity (Cotes and Reed, 1984). This may well be true, but has limited relevance in emergency situations where speed of action is necessary. Fast rescue craft crew operating within the offshore oil industry are also required to perform tasks which impose severe physical demands, with the task of casualty recovery noted to be particularly strenuous. In addition to meeting the medical standards specified under the Merchant Shipping Regulations additional physical fitness standards have been recommended (David et al, 1985). These concentrate on muscular strength rather than cardiovascular fitness parameters. The fire-fighting visual standards make no specific reference to cataract surgery. However, the improvement in visual acuity which can be obtained from cataract surgery cannot be dismissed. It should be considered best practice offshore, where the recruitment pool is limited, to assess each such case and continuing fitness on an individual basis. Review of Occupational Health Records The figures from the occupational health review were too small for useful comparative analysis, but do show the need to concentrate on medical fitness for fire-fighting independently from fitness for any other function. Even in this small sample a number of medical conditions that may impact on suitability were found. Although the medical Conclusion and Recommendations The current selection method for choosing emergency response rescue team (fire-team) members on an offshore installation does not specifically take account for the medical and physical demands, which are imposed, from this additional duty. However, the majority in 248 The recommendations made below should be considered as part of a strategy for ensuring that those who are trained for fire-fighting are able to meet these demands effectively and should be seen as additional to the medical assessment for offshore work. The health questionnaire should identify current health issues and any particular problems relevant to fire-fighting. Detailed reference to the musculoskeletal, cardiorespiratory systems should be made. The physical activity questionnaire, as a health promotion tool, would be of use to identify target actions where physical fitness is falling or is below standard. The physical examination should include assessment of height, weight, BMI, lung function and an assessment of vision. In addition, an assessment of aerobic capacity using a step test method and assessment of grip strength using dynamometry is recommended. An annual task related occupational health assessment is proposed, which could be performed by the offshore medic. The medic would require to be adequately trained and supervised, with any problematic cases being referred for medical review. The primary assessment should consist of a health questionnaire and a physical activity questionnaire followed by a medical and physical assessment. A holistic approach to the fitness assessment should be adopted, an idea which has already been proposed for both onshore fire-fighters. Effective fire-fighting also requires the optimum performance of the team. This itself depends on the ability to use the attributes of the team members most efficiently. Nevertheless, certain basic standards of fitness would normally be expected, as shown in Table 16. this study were found to be fit for the task when assessed using the onshore fire-fighting standard. There were exceptions and this has important implications for the future, particularly when considering issues such as the ageing offshore workforce and reduced manning levels with the requirement to maintain an effective fire-fighting team. Table 16 : Recommended fitness standards for offshore emergency response rescue work Parameter Age Recommended Standard No limit BMI < 30kg/m2 Vision Uncorrected Acuity Corrected Acuity Colour Vision 6/60 N48 6/9-4 N12 Normal or mild green deficiency (All defects require referral for medical assessment) Spirometry FEV1 , FVC, PEFR Within normal range Aerobic Capacity ≥ 40 ml/kg/min (minimum) ≥ 45 ml/kg/min (preferred) Grip Strength ≥ 40kg Leg/Back Strength No physiological testing, assessment based on history With further evaluation as appropriate Body mass index (BMI) should normally be less than 30 kg/m2, with lung function test results within the normal range. The visual acuity should be similar to that required for onshore-retained fire-fighters (6/9-4, N12 at 30 cm with both eyes open, using visual aids, if necessary, with an uncorrected acuity of 6/60, N48). Visual aids, if required, must be compatible with fire-fighting. Where a colour 249 Chia KS, Jeyaratnam, Chan TB, Lim TK. Airway responsiveness of firefighters after smoke exposure. BJIM 1990;54:228-31 vision defect is identified, referral should be made for further medical evaluation. Aerobic capacity should be ≥ 40 ml/kg/min and ideally ≥ 45 ml/kg/min. Where this standard is not met, other parameters need to be assessed to determine what fire-fighting duties could be performed, and what can be done to improve aerobic capacity. Grip strength should be ≥ 40 kg to ensure adequate upper body strength. No assessment of leg/back strength has been recommended due to the concerns relating to the safety of such a test. No specific age limit for performing fireteam duties is recommended either, but when fitness is assessed longitudinally, cases where performance is noted to deteriorate should be assessed on an individual basis.

So I think I know a little bit about what I’m talking about. What the audience will know is that all the fire fighters onshore are volunteers. Offshore they’re not and it’s the position that the company employs them for, such as electricians, operations, safety, whatever, that drives them into being the ER team offshore. So, it’s a position that they don’t volunteer for, they’re just put into it. I’m not getting all of this in the right order maybe, but what does the author of the presentation we just had suggest, if they don’t meet the criteria? Does the company stop employing them or at some stage in the game say well, you can’t be in the RT so we can no longer employ you? Scottish Office.

Question - Tony Parkinson, Noble Drilling, for Texaco Not really. What are we going to do about it? When we heard about this step test, it was more stress - people were worried that if they failed it, they might be thrown out of the RT. Would they lose their job? What are we suggesting happens from this? The company has got to be aware that if people are required to do these tasks then they are possibly putting themselves at risk. They will get tasks done but will it be in sufficient time? In terms of the step test, if it’s done accurately as I said there is a 10% error, so I wouldn’t accept that there are these wide variations that you’re quoting. It obviously depends on the training of the individual that’s done the test and if they’re done in optimal conditions even the standard is less than a 10% error. Answer - Dr Allan Prentice, Aon Occupational Health What I was doing was suggesting a particular standard. Obviously these sorts of questions have to go directly to the employer in terms of what they do if someone isn’t meeting the standards. I accept the point about obviously voluntary recruitment for the fire teams offshore. Obviously there’s a restricted choice that is available and therefore people may not be volunteers as such, they may be coerced into these positions. They may be very reluctant volunteers and that’s no motivation really to achieve a standard. If you think you might lose your job, well that is, but I don’t In terms of the issue of what happens to people if they do not meet the standard; I would say the same as what happens in terms of onshore fire teams, that really we have to have fitness training programmes in terms of ensuring that people do reach these standards. 253 254 AGEING OF THE OFFSHORE WORKFORCE IN THE NORWEGIAN OFFSHORE INDUSTRY: IMPLICATIONS FOR SAFETY AND HEALTH Dr Eirik Bjerkeboek, Dr Helge Wiig and Dr Hilde Heber Norwegian Petroleum Directorate face a shortage of labour in several sectors within the next decade, giving a new focus on the positive effects of continued/increased participation of senior personnel in the work force. Challenges associated with ageing and increased disablement of the work force is therefore currently addressed by the government as an important topic. Introduction The Norwegian offshore oil industry has grown through more than three decades into a mature industry with well-developed infrastructure and a fairly stable work force employing 15-20.000 persons depending on variations in the activity level. Although new oil and gas fields regularly are found and developed, a significant increase in the amount of labour invested. New technologies and new organisational designs continuously reduce the amount of human energy spent on upstream activities. In addition to the implications for workers health and national economy, is has more recently become apparent that the demographic and organisational changes seen in the offshore industry also may cause serious conflicts with established and well proven strategies for emergency preparedness and reduction of harm during safety critical events. During this period the recruitment strategy has changed. In the early days there were good job opportunities for low educated workers. During the last two decades mainly experienced and specialised workers have been recruited. Within the traditionally hierarchical organisations of the petroleum industry, offshore career opportunities have generally been recognised as scarce, and a pattern of low mobility and increasing workforce age has developed. Thus, the Norwegian Petroleum Directorate (NPD) as the governmental agency responsible for following up legislation on working environment, workers health and safety on the Norwegian continental shelf, the (NPD) addresses these challenges seriously and in collaboration with trade unions and the NOIO. Norwegian legal requirements pertaining to work environment and health for ageing employees External recruitment has been low for years. Transferring personnel from already established offshore organisations has mostly staffed the more recently developed organisations on new installations. A consistent trend of downsizing in existing organisations has enforced the picture of a stable and steadily aging cohort. As a background for a description of the changes and challenges that increasing workforce age raise with respect to health and safety, a brief summary of relevant legislation and regulations is given. The general mandatory retirement age in Norway of 67 years is established by agreement between employers and employees organisations. This age level is high compared with most other European countries. For special groups of employees, such as police, firemen and seamen, the retirement age is lower, set by agreement between workers unions and employers. The mandatory age of 67 applies to most employees in the petroleum offshore industry, although several companies The challenges pertaining to increasing average workforce age has been addressed since the early 1990s by the different trade unions, The Norwegian Oil Industry Organisation (NOIO) as well as the government. During the same time period the average age of the Norwegian work force as a whole has increased, accompanied by large increases in the rate of disablement pensioning, increased health problems and large increases in health related costs. At the same time predictions show that Norway will 255 offshore that allow those who wish to continue working until mandatory retirement age. have special agreements on lower pensioning age. The Norwegian Working Environment Act states as objectives, to secure sound employment conditions and meaningful work situation for the individual employee. Furthermore § 14 e states that; employer shall organise and arrange the work giving due consideration to age, proficiency, working ability and other capabilities of the individual employee. This act also requires that employers show attention to workers welfare and dignity, which is of relevance in handling the consequences of ageing. Changes in age and health in the work force in the Norwegian petroleum industry In order to monitor the situation, the NPD carried out to surveys on workers age and health in the offshore industry, in 1992 and 1998 respectively. These surveys included the major part of all operating companies, ship/rig owners, and entrepreneur/service companies active on the Norwegian continental shelf. The information presented from the 1998 survey represents aggregated statistics from approximately 11000 employees, with a fair distribution between the different industrial categories. This is about 2/3 of the total population carrying out regular work on the continental shelf. Staffing on supply and standby vessels are not included in the survey. These requirements are further elaborated in Regulations relating to systematic follow-up of the working environment in the petroleum activities. Here a number of paragraphs state requirements relevant to the topics of this paper, such as; monitoring and follow up adverse health effects from long term exposure, as well as arrangement and organising of work operations. Figure 1 shows the age distribution in 1992 and 1998, demonstrating a clear shift towards higher age. Mean age for the population increased from 38,8 to 42,9 yrs. The increase is largest within operator company employees on permanent installations. The increase in mean age of ca 0,7 yrs/yr. is not due to migration effects e.g. from educational reforms, which cause similar increases in mean work force age in Norway as a whole. Low recruitment of young employees combined with low mobility in existing work force are the most probable explanations. It should be noted that the increase in age probably is attenuated by a larger proportion of senior workers exiting from offshore employment during the large number of reorganisations in the industry lately. There are also mandatory health requirements for offshore employees in the petroleum industry. These requirements are related to functional requirements in emergency preparedness situations, and are not related to working ability. All employees carrying out work on offshore installations therefore need to be certified by a physician, obtaining a socalled health licence. This licence has to be renewed on a two-yearly basis and can be revoked at any time by company doctors or any other physician.

This may be due difficulties determining work related cause-effect relationships, especially of long-term exposure and for complaints with multi-causal origin. A mean total sick leave of ca 7 days/employee offshore is low, however compared to ca 17 days/employee in comparable onshore industries. This discrepancy is probably contributable to several factors. The health requirements, as well as special working conditions offshore probably result in a marked “healthy worker” selection effect. Also the special shift arrangements contribute to low reporting by the companies. With a 2 week on – three/four week off schedule, sickness during off schedule is most often not registered by the companies. A comparison of the offshore data with sick leave onshore is difficult. No similar age distributed data for the onshore population exist, but the national rate of long-term sick leave (more than 14 days) shows a similar trend in age development and a consistent increase in long duration leave during the last five years. This supports research from Statistics Norway (personal communication), showing that older workers stand for the major part of long-term sick leave. Off shore the most aggravating result is a mean value of 44 days sick leave/employee/year for operating company personnel over 60 years. The increase in health problems and sickness with age is also clearly demonstrated in the rate of loss of health licence, shown in figure 3. The blue columns in the figure show the rate of loss of licence in 1998 relative to the proportion of employees in each age group. 257 % of work force within age group 12 10 8 6 4 2 0 20-29 30-39 40-49 50-59 60 + Age loss of licence disablement pensioning Figure 3 Rate of loss of health licence in the offshore industry work force offshore environment.

The major proportions of the existing work force are now between 40 and 60 years. Also, a major increase in early retirement and increased recruitment of young personnel is unlikely. Thus the old-timers will have to carry on working with similar exposure levels as they have had up to now, with a high risk of sickness and long-term sick leave as they approach the end of their careers. out in the offshore • Long-term shift work. Since mobility is very low, most employees tend to remain in a highly demanding shift schedule for a more prolonged period of time than workers onshore. Increased risk of sickness from working shift work, especially night shifts, is well documented in the literature. However the relationship between ageing processes and effects of shift work is less studied. • Shift arrangements with long on-duty periods and even longer off-duty periods. This arrangement clearly presents many employees with problems handling the relatively constrained life offshore, the repeated separation from family, as well as problems associated with fragmented participation in family and social life during off-duty periods. • High physical demand/work load often combined with poor conditions for manual handling of equipment. This risk factor is well documented in the literature, resulting in both acute and chronic musculo-skeletal sickness. • Hard surfaces, steep stairs and ladders. Several company doctors attribute the age related increase in prevalence of skeletal illness in the lower extremities to these factors. • Motivational factors. The organisations on permanent offshore installations have, up Possible causes of increased health problems in older offshore employees Between the employers and employees organisations it is a hot topic of debate, whether offshore working conditions represent especially harmful effects, which again are reflected in more adverse health effects than those found in comparable industries onshore. Although we do not have statistics on the causes for loss of licence it is generally believed that musculo-skeletal and cardiovascular conditions are main contributors. These are also important causes for the increasing rate nationally of disablement pensioning. On the national scale, however, mental sickness such as depressions and neuroses is a large and the most rapidly increasing diagnosis group. Pertaining to the age related increase in sickness, the exposure factors that most clearly 259 safety requirements, with early withdrawal as a likely result. to now, been rather bureaucratic compared to similar industries onshore. Also, for the large majority of employees there are limited opportunities for career development. It is possible that these conditions, combined with customisation to long periods of leisure time, are factors that reduce motivation for a long working life, which again may affect health and working ability. • Uncertainty and anxiety associated with the increases risk of travel and period of stay on the installations. In our effort to ensure that early and involuntary exits from offshore work due to health complaints are minimised, we need to focus both on measures directed towards the older portion of the workforce. However at the same time measures must be taken to ensure that the younger part of the population have working conditions that allow long-term occupation in the offshore business. The NPD directs its effort to secure workers health and welfare mainly by; Of these factors increased individual risk of illness is well documented for long-term shift work and long-term exposure to unfortunate physical load and walking/working on hard surfaces. For the other factors changes in risk with age has not been systematically examined or documented. • Issuing an adequate and updated regulatory framework that encompasses new knowledge on risk factors, identification of risk and risk handling measures. • Following up of the regulatory framework through audits and quality revisions. • Counselling, including transfer of experience, surveys and direct counselling in disputes involving interpretation of the regulatory framework In addition there are a number of other factors that may have negative effects with increasing age, such as; rapid rate of organisational and technical change; increased learning demand; increased use of advanced technologies; and the increasing use of non-hierarchical organisations. However, these factors are not specific to the offshore industry. In all these activities, the focus on consequences of ageing will become more important in the years to come. For instance, the major update of the regulatory framework, to be issued this year, focus on work arrangement and organisation is increased. While the main objective up to now has been arrangement of each separate work place or operation to obtain low-risk of injury or sickness, the new regulations require a broader approach where total work organisation and restitution shall be included in risk assessment. NPD strategies on ageing and health The NPD has during the latter years increased its attention towards the safety and health challenges presented by an ageing work force. Our objective is to ensure that workers health and well-being is appropriately attended to, allowing those who wish so to continue their career till retirement age. Furthermore to ensure that the industries emergency preparedness organisation and contingency plans are adapted to the present and expected changes in age and health. In our effort to ensure that long-term employment offshore is compatible with a good health outcome, we have a main focus on preventive strategies: • Obviously, a good design is of essence in creating work and restitution environments that allow long-term employment without undue negative health effects. The NPD focuses both on requirements for the design process and the design itself. • Arrangement of work places and organisation of work is followed up closely, combined with a follow up of general screening of personnel and reporting of work related sickness. A special focus is given to the follow up of effects of organisational restructuring in the business Search and rescue (SAR) teams are important components of most emergency preparedness organisations on the installations in the Norwegian petroleum industry. In order to meet the NPDs functional requirements for emergency preparedness, many companies have established specific requirements for minimal physical capacity for participants in SAR team. Older workers do not easily meet these limits. In some cases SAR-team age limits well below pensioning age have been introduced as well. We thus see a possible scenario where downsizing of organisations and increasing age comes into conflict with 260 can only be made if employers and employees collaborate in defining and carrying out unified preventive strategies. The NPD is also active in ensuring that the industry has an adequate monitoring and follow up of work related disease. Furthermore to ensure that both systems and activities are in place to follow up and support to those employees who either develop, or have higher risk of developing work related health problems. The strategies of the industry and the employers o Recently the NOIO have initiated a project on age and health, inviting the major trade unions, the organisation for ship and rig owners, as well as governmental agencies to participate. The aims of the project is to reduce sick leave and disablement pensioning and develop proactive measures for handling the expected rise in mean age for offshore workers. Through this project the NOIO also aims to make offshore employment more attractive to senior personnel. Adequate measures to prevent the number of early exits from working life due to health problems are now prioritised also on a national level. A governmental committee has recently suggested several measures that may allow older workers to remain in active work, despite increasing health problems: • Increased maximal period of self-reported sick leave, a period where employee is allowed to stay away from work with presumptive sickness without physician’s evaluation. • “Active sick leave”, an arrangement where the employee regulates participation in work based on a self-assessment of the ability to function adequately. • A more active collaboration between the local social security offices and employer in rehabilitating employee after long-term sick leave. • Increased flexibility in disablement pension arrangements, allowing a smaller disability fraction for allotment of partial pension. Besides a closer survey and statistical analysis of relevant data from the industry, the project aims to provide a knowledge base and a political platform for launching more practical preventive measures in the future. Whether this strategy succeeds remains to be seen. The NOIO and the trade unions still disagree on major issues such as: • Are offshore employees subject to negative health effects that put them significantly more at risk than colleges onshore? • What is a reasonable pensioning age for offshore employees? Due to the special offshore shift arrangements, as well as the relatively small opportunities that the petroleum industry offer for onshore rehabilitation, is questionable whether the suggested measures will have much effect for older workers offshore. Hopefully the descriptive and analytical part of the project will give some answer to the first question, while the practical part of the project will give results that allow older worker to remain in offshore employment without negative health consequences. From the NPDs point of view it seams clear that significant progress on improving working conditions and health risk for older workers 261 262 IMPACT OF HEALTH SURVEILLANCE AND PROMOTION ON OFFSHORE ACCIDENT RATES Dr Kathryn Mearns, Industrial Psychology Group, University of Aberdeen management, ‘stop smoking’ and advice on diet and nutrition. In the USA their main objectives are to promote employee health and reduce corporate health care costs, however other documented spin-off effects include: • Reductions in employee absenteeism and lateness • Fewer accidents • Less worker compensation costs and employee turnover • Greater employee loyalty and commitment • More creativity and effectiveness in decision-making amongst employees • Better labour relations and employee recruitment • Improved company image Unlike the USA and some European countries, e.g. Norway and Sweden, where legislation has mandated health promotion, Britain has lagged behind in promoting health at the workplace. This imbalance has been redressed to some extent in the HSE document ‘Good Health is Good Business (www.hse.gov.uk) which focuses employers’ attention on identifying and mitigating against potential occupational health risks at the workplace. Occupational health is not a new issue for the offshore industry and the HSE theme ‘good health is good business’ underpins some of the management systems adopted by the industry. However, it is worthwhile noting that whereas the issue of occupational health is receiving the attention it merits, there is comparatively little research conducted on the impact of health promotion programmes on the wellbeing of offshore workers. Abstract The Aberdeen University Industrial Psychology Group have just completed a project entitled ‘Benchmarking human and organisational factors in offshore safety’ involving the HSE and 13 offshore operator and contractor companies. The exercise involved using questionnaires to collect safety information for the previous year for a particular installation from three different sources: 1. The offshore workforce, in terms of how they perceived the installation’s current state of safety; 2. Managers, in terms of recording health and safety management policies and practices; 3. Safety performance data in terms of selfreported accidents from workforce respondents and official accident and incident rates (e.g. RIDDOR) Nine installations were compared according to their scores on each section of the questionnaires, and relationships between the scores on the questionnaires and accident and incident rates were explored. A section in the management questionnaire requested information on health surveillance and promotion and a high significant correlation was found between scores on this section and the rate of LT1>3 (rho9-0.76). In addition, there was a high and significant correlation (rho9-0.81) between scores on this section and the proportion of workforce respondents reporting an accident in the previous year. This paper will present the methodology used to collect the data and discuss the possible implications of this finding. A pilot study on the extent of health promotion activities in the offshore oil industry was conducted by Mearns and Fenn in 1993 (HSE, 1994). The Medical Directors of 41 offshore companies operating in the UK sector and 21 companies operating in the Norwegian sector were surveyed about the number and types of health promotion programmes currently in place on their installations and the individuals/organisations responsible for these programmes. In addition, 145 UK and 76 Norwegian offshore medics were surveyed about the need and priority for health Introduction The literature on workplace health promotion or employee ‘wellness’ programmes is extensive with the USA leading the field in initiating, implementing and assessing the effects of such programmes. These programmes usually focus on weight reduction, hypertension control, fitness training, medical screening, stress 263 promotion offshore. The overall response rate was 36% (53% UK rig medics: 25% Norwegian rig medics: 14% UK Medical Directors and 29% of Norwegian Medical Directors). Most respondents gave offshore health promotion a high priority because of the ageing workforce and their relatively poor lifestyle (smoking, lack of exercise and overeating). Various health promotion activities were in operation but were limited to 47% of the Norwegian installations and 36% of the UK installations surveyed. Results With respect to the current paper the area of interest lies in the results obtained from the Safety Management Questionnaire (SMQ). Analysis of data from the nine installations which provided data in both 1998 and 1999 (i.e. were common to both years), took the form of rank correlations between the six subsections of the SMQ, the total SMQ and four outcome measures. These outcome measures were LTI>3 days, RIDDOR data (although it is acknowledged that this indicator is an aggregate of other lagging indicators); Near misses and Dangerous Occurrences. A pattern of negative correlations was predicted and found: favourable scores on the entire SMQ were associated with lower accident and incident rates. All significant negative correlations involving sub-scale scores were confined to two areas of management strategy - health promotion and surveillance and health and safety auditing. In particular in 1998, high scores on the full sub-scale ‘Health promotion and surveillance’ (which included both quantitative and qualitative data) were significantly associated with lower lost time injury rates (rho -0.76). Responses to an abbreviated sub-scale including just quantitative data were significantly correlated with lower rates of dangerous occurrence (rho –0.79), near misses (rho –0.76) and RIDDOR (rho-.78). A pattern of negative correlations was also found in the 1999 data, however, the effects were not as strong. From these results it is proposed that the benefits of health promotion and occupational health programmes may be realised through a number of possible processes: Method More recently (Mearns, et al. 2000), Mearns, Whitaker, Flin, Gordon and O’Connor have carried out a health and safety benchmarking study (sponsored by 13 offshore oil and gas companies and the HSE). This study compared the health and safety performance of 13 offshore installations (including fixed production platforms, well-service vessels, FPSOs and drilling rigs) on a range of leading and lagging performance indicators. The leading indicators included safety climate surveys of the offshore installations in which respondents indicated their involvement in safety, safety behaviour, safety attitudes, satisfaction with safety measures and satisfaction with communication about health and safety. In addition, HSG 65 (HSE 1997) was used as a model for development of a Safety Management Questionnaire (SMQ), which recorded a range of safety performance indicators used in other health and safety benchmarking programmes. These covered six main areas: i) Health and safety policy; ii) Organising for health and safety; iii) Management Commitment; iv) Workforce Involvement; v) Health surveillance and promotion; vi) Health and safety auditing. The participating installations were also required to provide details of their management structure, including the position of safety professionals within the hierarchy, and their accident and incident statistics including RIDDOR data, near-misses, visits to the offshore medic and number of cards/ reports from behavioural modification programmes. Relevant documentation to support the questions asked in the Safety Management Questionnaire (SMQ) was also requested. All information related to the period June 31st 1997 to June 31st 1998 (for the 1998 benchmarking survey) and June 31st 1998 to June 31st 1999 (for the 1999 benchmarking survey). 264 1. Investment by the company in these areas fosters perceptions of company commitment and builds worker loyalty in areas such as safety behaviour 2. Health plans and health programmes improve worker health directly and ‘immunise’ against work-related injury (although there is also a possibility that they mask early signs of occupational ill health). 3. Health plans and health programmes ‘weed-out’ unhealthy workers leaving a ‘survivor population’ that are best suited to the offshore environment, both physically and mentally. However, it should be noted that this process is already in place through the mandatory regular 4. crew, including contractors (i.e. those members of the workforce who are most familiar with the installation) and would request the following information: • Demographics (age category, years worked offshore, years worked on current installation) • Perceived management commitment to health and safety (both offshore and onshore), • Perceptions of work pressure • Perceptions of social support • Perceptions of stress • Self-reported health and well being, coping strategies, safety behaviour and accidents/injuries/illness. offshore medicals that workers have to pass in order to work offshore. A final mechanism can also be suggested whereby an installation that is good at heath promotion and health surveillance may also be good at the risk assessment and control approaches and training. These processes are presented speculatively. Indeed, it is important to emphasise that the data presented here are correlational and relatively limited. There is therefore a need to conduct further research in order to corroborate the findings and to understand the mechanism behind any effects. In other words, apart from showing associations between these variables it is important to model potential cause-effect relationships. All information collected would be anonymous and confidential. There are three questions that can be specifically posed with respect to the above: 1. 2. Questionnaires would also be sent to a senior manager associated with the installation requesting information on the following: • Type of health promotion programmes on the installation and how long they have been in place. • Details of how health issues are communicated to the workforce. • Whether an occupational health plan is in place and what percentage of the health plan has been completed for the previous year. • What provision there is for routine health surveillance of workers. Here, there is a need to distinguish with surveillance for medical fitness and more frequent surveillance for auditory problems and dermatitis, for example. • Whether there are facilities for health review on return to work after sickness • Whether counselling, support and professional advice are made available during periods of ill health or stress. For example, uptake of Employee Assistance Programmes (EAPs) could be measured, as could the extent of rehabilitation after injury or ill health and follow-up of the individual’s well being and progress while still absent. • Whether there are mechanisms for identifying and helping individuals with alcohol or drug related programmes. In addition, how the process for identifying and helping individuals is actually carried out may be of particular importance. • Number of personnel visits to the sick bay in the past year. An attempt will be made to categorise these visits according to various criteria, e.g. major injuries, lost Is enhanced health and fitness associated with a perceived increase in ability to cope both physically and psychologically with the offshore working environment? In other words, increased feelings of physical and mental well-being have a direct impact on physical and psycho-social stressors leading to improved ability to cope, greater attentiveness and ability to respond to potentially hazardous situations Are increased investments in health promotion & surveillance indicative of higher levels of management commitment to safety and a culture of care and concern? The effects of this on the workforce could operate through two possible mechanisms a) a higher perception of self-worth leads to personnel taking more care and experiencing fewer accidents, b) an improved perception of company commitment to worker wellbeing builds loyalty in areas such as safety behaviour? These hypothesised relationships provide the basis for a proposed new study, investigating the impact of health promotion and surveillance on accident and incident rates offshore. The proposed methods for collecting the data are through questionnaires and interview techniques. These should be used across as large a sample of installations as possible (minimum 10), preferably including a sub-set of installations on which there are no health promotion and surveillance programmes. The questionnaires would be directed at the core 265 time injuries in excess of three days, first aids, distribution of medication, ‘no treatment’. A mechanism will also have to be put in place to monitor repeat visits to sick bay. Care will be taken so as not to jeopardise patient confidentiality.

My role really is to bring to a close what I hope and believe has been a very successful three day conference. Summarising a three-day conference, three days of quite intense presentations, discussions and debate is not an easy matter. I’m not sure whether it’s stress or pressure I’m under at the moment. The aim of the organisers was to raise the profile of what is often a Cinderella subject. I realise that obviously those of you who are here have a particular interest in occupational health but there is no doubt that there is a struggle in drawing the attention of industry and the population at large to health issues because they tend not to be so visible as the classic accident situations. The theme of partnership I think was extended into the second day where certainly the role of good design in occupational health, and of course the ever present physical, chemical and biological agents, emphasise how much good work has been done in these areas. We heard about a number of cooperative projects and there is clearly a considerable commitment to tackle occupational health problems. Finally, today we heard how some of the difficult issues, and let’s be honest, these are even more tenuous occupational health issues such as stress and workforce well-being issues are being tackled. Again the partnership in particular was emphasised by Fiona Farmer this afternoon and I was interested to hear as I was writing my summary that she emphasised the important role of partnership in developing well-being and good health. The other thing I think these sessions did do as well was emphasise the importance of the workforce involvement and employee and employer awareness to jointly tackle these issues. I hope the conference has provided opportunities to share views and challenges and successes and perhaps failures. I believe the underlying message that seems to be coming through here is one of partnership and shared responsibility. Certainly the first day set the tone for that with Bill Callaghan from the Health and Safety Commission coming to the conference and Malcolm Brinded (Shell), both emphasising aspects of shared responsibility and the commitment of both the regulator and the industry at large to tackle occupational ill health. It’s certainly clear to me at any rate that all health and safety matters. The conference has covered a wide range of occupational health issues and I think it comes as no surprise that the key topics emerging as creating significant concern are stress and musculoskeletal issues. HSE is already tackling aspects of musculoskeletal disorders as part of its current initiatives. We’ve also recognised stress as a problem that we have to get to grips with. Certainly we are looking towards next year of trying to raise the profile of our approaches to stress and see how the industry can further deal with that. TAPE CHANGE, therefore bit missing here We shouldn’t forget though in looking at partnership that it’s the employer that does hold the key. The employer can facilitate this and it’s encouraging to see this renewed commitment, certainly as a result of the conference that was held under the auspices of the Offshore Industry Advisory Committee to develop cooperative working. And in particular, I think this has been emphasised at least once today, the importance of identifying the statistics, of coming together, because the RIDDOR statistics, in other words the statistics held by the regulator are pretty thin because of the nature of the reporting, which has already been criticised today. If I could put a quick plug in here for musculoskeletal issues. There are to be two seminars later this year and I think there’s information in your pack and there will be information on the HSE website of two seminars, one in Aberdeen and one in Great Yarmouth, looking at musculoskeletal issues. We must not forget in looking at emerging issues, that the traditional problems still haven’t gone away. We are still getting dermatitis, we still need to tackle the problems of noise, chemicals, other hazardous materials. 267 The effects of them may not be immediately obvious but they do need to be dealt with. I hope you are taking away ideas from the conference. It is important that it has stimulated your thoughts as to how you might proceed on the issues. HSE certainly is taking away a number of issues and certainly Ron and his colleagues who have been here will be taking points. In particular, we have taken to heart the criticisms of ill health reporting and that there is a review of formal accident, incident and ill health reporting which obviously we can feed in. We have also taken away some good examples of good practice and best practice which as a regulator who can move across the industry, we can provide an opportunity to deal with this. I want to take this opportunity of reminding you of the role that industry has got in terms of the Step Change initiative because there is a great emphasis on improving the cooperative working as I said earlier. Certainly distributing examples of good practice and best practice across the range including occupational ill health, dealing with occupational ill health, is invaluable and that shared knowledge is of great importance. It finally remains for me to thank all the speakers and chairmen and all the delegates for your commitment in stimulating debate. I overheard a conversation at lunchtime complaining there wasn’t enough time for discussion generally over the three days. I think that’s always a good indicator of a challenging and interesting conference that needs to stimulate debate. It’s always difficult to single out individual contributors but I would particularly like to take the opportunity of thanking Kevin O’Donnell who has done extensive work in organising the conference and Vee Gatrell and the team from DIAS, the publications organisation for their organisation. Also, and it looks like he’s gone, but I was asked to thank Alistair in the booth at the back there, who has had to tackle the various IT gremlins, and of course the Aberdeen Conference Centre for providing the venue. Finally can I ask you if you could take time to provide us with some feedback. There are forms in your pack. That would be very useful. Thank you very much.
