EDITORIAL

Adapting to change Henrik O. Madsen

Henrik O. Madsen admits that ‘we must never be content’, because the world is constantly changing. The recently appointed Chief Operating Officer of DNV’s Business Area Oil, Gas and Process Industries maintains that technology and markets are developing at such a rate that ‘our biggest enemy at the moment is resistance to change.’ Madsen appreciates that DNV is rapidly winning new roles in the oil and gas industry. These come in addition to our traditional roles as a classification society for mobile offshore units, as a provider of certification or verification for fixed offshore installations and pipelines, and as a provider of marine warranty services. In addition, DNV offers a wide range of risk-management services: from life-cycle risk management and integrity management to safety, environmental and human-factor consultancy. The ability to swiftly respond to change, and a committed approach to further innovation and improvement, will ‘separate the winners from the losers.’ In response to changing market conditions, particularly in the highly promising deepwater sector, DNV is actively developing both new and existing services, some of which are covered in this issue of DNV Forum. In addition to our offshore articles - which include a special focus on activities in the Gulf of Mexico - we have been to Iran to listen to people influential in shipping; we delve into BHP’s management approach, and we present a timely article about our software-certification services, a growth area for DNV. We also feature a ‘viewpoint’ article addressing the prime issues affecting Brazil’s oil and gas industry. Our themes, as usual, are varied, from shipping to asset management and the environment; from personal interviews to a study of risk-based inspection. At this time of rapid change in the markets which DNV serves, it is appropriate for our pages to reflect the wide diversity of products and services DNV offers - and their adaptability to new and developing situations. We hope this issue makes for stimulating and enjoyable reading.

VIEWPOINT

THE FUTURE LIES IN TECHNOLOGY… AND Most of the significant developments in deepwater exploration and production during the past 25 years have taken place in Brazil. And the pioneer has been state-owned oil company Petrobras. Ricardo Luis Beltráo, Petrobras Installation Technology and Engineering Group manager, here discusses the prime issues affecting the industry, including developing technology and effects of the Government opening up the sector to international companies.

OFFSHORE MANAGEMENT

Managing change in Liverpool Bay Over 1.5 million people, including 22 Members of Parliament, in north-west England and North Wales have a ringside view of the Liverpool Bay oil and gas fields. The asset is operated by Australian multinational BHP Petroleum, in a joint venture partnership with Lasmo and Centrica Resources. With one of the four fields just five miles offshore, activities are very much in the public eye. So far, the Partnership has invested £ 23 million in measures to make the environmental systems even more robust, and to avoid damage to the environment in the future.

T

The Liverpool Bay field is situated justf the of coast of Liverpool and the tourist mecca of Blackpool, and close to the beaches ofthNor Wales, the W ir ral and Lancashire.

he Liverpool Bay fields are situated close to the tourist visi mecca of Blackpool and the beaches of North Wales, the Wirral and Lancashire. The crude oil from this asset is waxy, contains 2 per cent H 2S and has a strong, unmistakable odour. This combines to give BHP Petroleum challenges in both safety and the environment which are different from most operations on the U.K. Continental Shelf. Geology and geography have conspired to demand the highest standards of health, safety and environmental management.

BHP vice president David Walker and his team know that the slightest slip from these standards can result in oil on beaches,attention from the media, questions from politicians and demands from the public. ‘If one drop of oil gets into the sea,it will be headline news in a matter of hours’, he says. Baseline IERS (International Environmental Rating System) and ISRS (International Safety Rating System)audits conducted by DNV in 1998 set a benchmark for further progressand improvement in the field ’s safety, health and environmental performance. The BHP assetteam graspedthis opportunity for positive change, and a challenging improvement programme wasdeveloped and initiated. DNV was actively involved in all aspectsof this programme, and engineers and consultants from the London, Stockport and Aberdeen offices became regular tors to the offshore installations, onshore processing plant and BHP’s London headquarters.

OFFSHORE MANAGEMENT

Measurable improvements In December 1999 a repeat of the DNV audits measured the improvements, and both BHP and DNV were delighted with the significant achievements that had been made. Level 5 awards in both the ISRS and IERS were indicators of real progress, and David Walker and his Asset Leadership Team were quick to recognise the efforts of the workforce in accomplishing this successful result. Relativelyminor incidents which havebeen exacerbatedby the field’s location haveresulted in intense scrutiny from the industr y regulators, local authorities and tourist boards. Environmental pressure groups have also exerted pressure on local and central government that has increased the attention paid to BHP Petroleum. ‘We have worked very closely with DNV,’ explains David Walker. ‘This involves behavioural analysesand assessment,change management, training, environmental consultancy, safety engineering and general safety, health, environment and quality support.’ DNV has also played an active role in BHPP’s redesign and restructuring of the field ’s management and operating systems and structures.

Emergency response ‘We have reviewed our accident and incident reports in great depth to be sure that we get to the root causesof the problems,’ statesWalker. ‘We’ve collaborated on joint project teams with DNV to see how to improve our emergency response, and through safety engineering have made sure that we have the correct equipment in place, and that safetycritical elements are fully addressed. By looking at issuesincluding our human factors performance, we are generating procedures that are robust, clear and easyto use. We have also tried to influence the company’s safetyand environmental culture – and we’re achieving results. Through measurementscarried out using DNV’s IERS and ISRStools, we can show politicians, regulators and stakeholders that we’re continuing to improve. DNV has also acted as an independent competent body for the Department of Trade and Industr y to verify the appropriateness of the company’s safety, health and environmental management systems. ’

LIVERPOOL BAY ASSETS • Operated by BHP Petroleum (46.1% interest), in a joint venture partnership with Lasmo (45%) and Centrica Resources (8.9%) • Six offshore platforms, plus one storage/loading facility • One onshore gas processing terminal at Point of Ayr, North Wales • Gas pipeline from Point of Ayr to Connahs Quay Power Station • Waxy crude oil containing 2 per cent H2S • Over 300km of intra-field pipelines

For BHP Petroleum, improved heath, safety and environmental performance is the key performance target for this field, which wasopened in 1996 and is expected to produce hydrocarbons until 2015.

Communication with stakeholders David Walker regards communication with all the company’s stakeholders as one of the basic prerequisites for success.He talks about the three Es – education, employment and the environment. ‘A Visitors’ Centre has been establishedat our Point of Ayr Terminal in North Wales as a part of the education programme. In the employment sector, new oppor tunities are providing work for a number of young people under the government’s New Deal Scheme. In the environmental sector, the company has restored land in North Wales. BHP organisesbirdwatching and community awarenessactivities, and managesa major project which helps restore eroded sand dunes and beachesback to their natural state. BHP provides mini-busesand cars to assistpeople to learn to drive in an area where the majority are dependent upon road transport. It also arranges road-safetyeducation for children in North Wales, and awardsscholarships to young people to study at technical colleges. ‘We feel we’re heavily involved as members of a BHP team,’ statesNick Jackson,the head of DNV’s core team. This consists of five employees from DNV’s offices in Aberdeen, Stockport and London, who have been assisted by some 30 other staff during the past year . Harald Bråthen

DNV FORUM NO. 2/2000


Equipment inspection and maintenance at Koch Industries’ Pine Bend (Minnesota) refinery has hitherto been based primarily on inspection history, with little consideration for consequences of failure or business interruption. Recently, however, risk-based inspection (RBI) has been recognised as a technology that could offer cost, risk and safety benefits for the refinery. By identifying where the risks were and how to control them, plant operators would save money and reduce risk at the same time.

It comprised a thorough review of the inspection history, process,corrosion, and materials of construction for all piecesof equipment. It also included the initial data collection, data entr y, data analysis,inspection plans and cost-benefit analysisfor each unit. Reports were prepared for each unit, which included the following: • API-RBI software files populated with the required data per unit. • Inspection plan guidelines based on projected risk five yearsafter the next turnaround. This consisted of tables and reports indicating the overall risk, likelihood and consequence factors, the recommended inspection methods and coverage for each equipment item, and each of the damage mechanisms identified. • Three sets of Process Flow Diagrams showing the basic information used in the study. One set included the operating temperatures and pressures. The second set included representative fluids, phases, and isolation devices for inventor y grouping. The third identified damage mechanisms, susceptibility (high, medium or low), corrosion rates, and materials of construction. • Detailed inspection plans for all process equipment. • Active damage mechanisms and process constraints/limits identified for pressurised equipment. • A cost benefit and risk reduction page summary. • Top ten risk items identified per unit. • Prioritised risk ranking of pressurised equipment. • Equipment database for management of equipment risk in

Simpler inspection procedures Previous inspection practices were internal visual and ultrasonic thickness (UT) measurementsfor general and localised thinning, and wet fluorescent magnetic particle testing (internal WFMPT) for stress-corrosioncracking (SCC) mechanisms.Now, in place of these practices, the refiner y uses a combination of external manual and automated shear wave UT for SCC detection, a combination of external straight beam manual UT and automated shear wave UT for the detection of hydrogen-induced cracking and stressoriented hydrogen-induced cracking, and UT thickness measurementsfor general thinning. Vesselentry is only considered if the use of an external technique is cost prohibitive or not effective in finding the damage mechanism. Other benefits of the implementation phase included the quantification of the risk of operating parameter changes, reduction in risk of leaks to the atmosphere due to material degradation, identification of opportunities for consequence mitigation, development of universal risk standards for Koch Industries as a whole, and consistent work processesto allow franchising to other Koch processing sites.

An evergreen future After completing the RBI implementation phase,DNV has now begun what is known as the Evergreen Process.This phase of the project will include the preparation of Management of Change Work Processesto ensure that the RBI software files are kept updated at all times, and the training of inspectors in the use of the software for analysisand updating. The refiner y plans to keep the RBI process‘evergreen’ by: • Putting new data into the software, • Re-running the analysis and inspection plans, and • Re-running the cost-benefit analysesto justify their time and efforts. Now the refiner y operators know where the risks are and what they must do to reduce them; and what the savings will be. Stuart Brewer

DNV class for

WORLD’S LARGEST MEMBRANE-TANK

LNG CARRIER

With her four cavernous membrane cargo tanks, the 69,000dwt SK Summit is one of the largest LNG carriers yet built. A few days after her delivery in August 1999 she commenced loading LNG in Qatar, entering service between Ras Laffan in Qatar and Pyeong Taek in South Korea, on an anticipated 25-year contract.

I

n October 1995 Korean Gas Corporation (KOGAS) and Ras Laffan LNG Co. (RasGas)entered into agreement to deliver 2.4 million tons of LNG to Korea every year for 25 years.Following this agreement, orders for six 138,000 m3 gas carriers were placed in Korean shipyards by Korean shipping companies. SK Summit,built by Daewoo Heavy Industries Ltd (DHI) to DNV class,is the first to be completed. DHI will build three of them.

The membrane principle Unlike the spherical tanks of a Kværner-Mosstype LNG tanker, the prismatic tanks of a membrane LNG carrier are fully integrated into the hull. The boundaries of the prismatic tanks form a continuous inner hull, comprising double bottom, sidesand deck; this achievesa hull structure well suited to absorb global loads as well as local loads from the cargo. The cargo containment systemis fitted inside the tanks, between the inner hull and the liquid cargo. The containment systemis designed by Gaztransport and Technigaz (GTT). It is built up asa cryogenic liner directly supported by the ship’s double hull. The liner includes the primar y (inner) and secondary LNG barriers forming two identical metallic membranes, and the primar y and secondary insulation forming two independent insulation layers.

14

DNV FORUM NO. 2/2000


TECHNOLOGY The metallic membranes are 0.7 mm thick and 500 mm wide, of 36% Invar nickel-steel alloy, offering a very low thermal contraction coefficient which makes the material well suited for the low temperature ( –163°C) to which it is exposed. These membranes act as dual barriers protecting the hull structure from exposure to the low-temperature cargo. The insulation boxes, filled with expanded silicone-treated perlite, are internally strengthened to withstand high-impact pressures and to absorb the energy resulting from the liquid motions and pressure head. The boxes are independently and mechanically securedto the double hull by meansof studsand couplers specially designed for their thermal insulation per formance.

A challenge for Daewoo Heavy Industries For DHI this contract meant not only a significant investment

Offshore LNG production LNG production using Floating Production and Storage Facilities has been widely discussedin recent years.The benefits are obvious, with LNG production at the source of the gaswithout the need for expensive pipelines to an onshore plant with liquefaction, storage and export facilities. The FPSOconcept allows for economic utilisation of gasfields in remote locations without the infrastructure or transport facilities needed for onshore liquefaction. This technology also opens up possibilities for development of fields which are too small to justify the traditional solution, as the facilities may be relocated to other areas when the initial field is depleted. The combination of a highly complex processplant on a vessel with storage tanks, offshore loading, and accommodation for a crew of around 50, represents challenges in both construction and operation.

but also a great challenge. DHI, familiar with well-known technologies for traditional ship construction, had to develop new design and construction methods for the building of these more advanced LNG carriers. New welding techniques, procedures and machines had to be developed, and welders for machine and

et Norske Veritas has been actively involved in Europe’s aerospaceindustr y since 1986, when it achieved its first contract with the European Space Agency, ESA – this was to monitor technical and safetyaspectsof the European mannedspaceflight programme. That same year, under the co-operative ‘Eureka’ umbrella, DNV helped initiate the joint-venture Formentor project, to develop a computer-based system to recognise and act on malfunctioning rocket equipment. In 1987 Nor waybecame a full member of ESA; DNV established its independent Space and Communications project unit to support its space activities, and today offers a comprehensive service in information systems,telecommunications, remote sensing and measurement, environmental control, and lifesupport systems. Then and throughout the 1990s, DNV has been involved in numerous projects which have dominated European space activities; some of them are highlighted on p. 18.

The Galileo project Satellite navigation systemsare already indispensable to a wide variety of transport users – civilian and militar y aircraft, worldwide shipping, and a growing segment of land transport. They have also – to wider publicity – helped explorers in the Arctic, the desert and the jungle. But current global navigation and positioning systems,the American GPSand RussianGLONASS, are militarily controlled, and the aim of ESA’s European Satellite Navigation Programme, ESNP, is to build a satnavsystemthat is under civil control, more accurate than existing militar y systems,and with greater integrity and long-term availability. DNV’s competence in software-systemcertification led to its involvement last year in the European Geostationary Navigation Overlay System,EGNOS, a research project to validate the concept of a European equivalent to existing global positioning systems. Prime contractor for this is Alcatel Space Industries. Taking up the story is Sophie Chevillot, DNV’s station manager in Toulouse: ‘This proved an important reference for DNV in our being appointed prime contractor to ESA for the next step in the ESNP work, a study contract for the Galileo systemsoftware certification. The Galileo project aims to place navigational satellites in orbit, as part-payloadsin future European or American rocket launches; DNV’s previous work in telemetry and software for ESA will stand us in good stead in its software certification. ‘Here in Toulouse, with support from DNV experts in Paris and in Høvik, we already have a respected position in advisory and certification services, including all the DNV Rating Systems, TickIt certification, and Project Risk Management – the latter, for example, for Airbus Industrie ’s A3XX series of aircraft.’

Software certification in practice As prime contractor to ESA in the Galileo System Software Certification study, DNV is responsible for three subcontractors: Aerospatiale Matra Airbus (AMA), employing 12,000; Matra Marconi Space (MMS), with 2,000; and software expert Laboratoire d’Analyse et d’Architecture des Systémes (LAAS). In addition, U.S.-basedCertification Services Inc. will act as consultant to DNV in the context of civil aviation require ments. The study will be in two phases,each of about a year. The first will identify software design fault-tolerance mechanisms for Galileo’s main subsystems,identify software-certification require ments for these, and propose a certification development plan. Second phase will parallel the evolving development of the Galileo systemand its architecture, and refine the proposals of Phase 1. Manager of the software methods department in AMA’s Systems and Services Directorate is Gérard Ladier. Explaining the company’s software development in Toulouse last month, he pointed out the growing impor tance of certification of safety-critical software. ‘All equipment suppliers to the aerospace industr y must meet the DO 178B international certification standards for avionics software.In Aerospatiale, we set up a dedicated team to develop software for on-board equipment, and haverecently been assessed to Level 2 of the CMM programme.

Gérard Ladier of AMA: ‘Some of theoblems pr we face may alr eady have been over come in other industries.’

‘There are common requirements in all critical software, whether it is in the aviation industr y, nuclear power generation or telecommunications. This latter is of growing importance, by the way, to all “life-threatening ” applications. Another characteristic today is that less software is developed in-house, and more comes from commercial suppliers in their own equipment; as DO 178B standards specify that the prime manufacturer must have total control over the end product, we have to develop new meansof testing and controlling such commercial off-the-shelf (COTS) equipment. Either we must cooperate with the supplier, to have accessto his systemsdocumentation; or design an architecture which can handle this “outside” software. ‘Among the advantagesthat DNV brings to avionics software certification is its knowledge and experience of other disciplines. Some of the problems we face may already have been met and overcome in other industries. DNV FORUM NO. 2/2000

Frédéric Voulouzan, MMS:‘High reliability is vital – after all, ther e can be no subse quent access to satellitedwar hare!’

‘Unlike the present GPS, performance of the Galileo system will be largely guaranteed; hence the authorities demand certification of the entire project, including the software. ‘ Looking further ahead, I foresee wide potential for other applications of software certification, such as telemedicine, nuclear power and even bank ATMs.’

A growing role for DNV Growing criticality Also in Toulouse we met Frédéric Voulouzan, deputy manager for products and services coordination in the Data Processing & On-Board Software Division of MMS. ‘Software certification is a new concept,’ he explained, ‘but we already apply a stringent internal quality regime. About 40 per cent of our work is for commercial clients, 60 per cent for ESA and similar organisations. For these latter we must meet, not Code requirements, but aerospace-industry developed standards. These reflect the need for very high reliability – after all, in most casesthere can be no subsequent access to satellite hardware ! ‘As more and more software is installed in aerospaceequipment, its criticality grows. For the past two yearsthe industr y has had a policy of “continuous software processimprovement”. There are two extremes of availability and reliability requirements: a rocket may have a service life of 20 minutes, its payload a life of ten to 15 years. So an essentialcriterion for spacesystemsand their software is fault-tolerance. Such technology may help cut certification costsby reducing the criticality of each individual element.

DNV’s contract manager for the current Galileo work is principal engineer Arne Kjensmo. ‘For many years,’ he says,‘DNV has been increasingly concerned about the quality and reliability of software and systems, particularly those which form part of safety-critical monitoring and control. ‘The growing proportion of software content in systemsand products in areas other than aerospace, such as telecoms, transport, energy, finance and the process industries, calls for increased attention to issuesof software quality. In September 1998 DNV agreed with one of the world’s leading telecommunications companies, L.M. Ericsson, to jointly develop worldwide software-quality services. DNV acquired 50 per cent of the Ericsson-owned company Q-Labs, specialising in software engineering and process improvements. ‘A step further in DNV’s goal of improving the quality of safetycritical software has been to focus on software product quality. An important milestone has been to enter into a strategic alliance with Isoscope SA in Toulouse, a specialist in software product evaluation and improvement services.’ R. Keith Evans

Key DNV aerospace contracts Following its early involvement in ESA programmes, DNV establishedin 1990 a new company, DNV Industrial Development AS, with separate space and defence departments: the former handled European aerospaceprojects such as the Columbus orbiting space station, Hermes shuttle and Ariane rockets, all then seen as vital in the successof an autonomous European space capability.

H

aving been appointed as programme manager for the process of independently verifying Greenhouse Challengereports, DNV’s Simon Daweshas his hands full. The verification of

challengers – enterprises participating in the programme – is well under way. The Australian Government’s Greenhouse Challengeis a voluntar y programme. It is basedon cooperative agreementsbetween Government and individual enterprises from all sectorsof the economy, describing baseline and forecast emissions and planned abatement actions. Achievements are reported against the planned actions. ‘The Challenge was launched in 1996, and we are now carrying out independent verification of the reports for the Australian Government,’ says Dawes. The current verification programme aims to have a number of Challengers’ progress reports verified by this summer. DNV’s role is to develop the process and manage the independent verification of the reported baseline inventor y, annual emissionsinventor y, and the abatement actions undertaken by the companies taking part. ‘ DNV managesa process that will see self-reported emission inventories and reported abatement actions of up to 30 Challengers in the first year verified by a team of independent verifiers,’ explains Dawes.Selectedfrom 13 major contenders, DNV’s role is to manage the independent verification process,which includes the identification of verifiers, matching participating enterprises with agreed verifiers, and oversight of the verification process. The results of this first round will be reported by August 2000.

Designed to abate emissions Enterprises join the Greenhouse Challengeto demonstrate their commitment to the abatement of greenhouse-gasemissions.Their early, voluntar y action will ultimately help Australia meet its Kyoto targets. ‘The programme is designed to abate greenhouse-gasemissionsfrom all sectors of Australian industr y, which account for about 55 per cent of the total,’ explains Dawes.The object is for enterprises to achieve maximum greenhouse-gasabatement, while enhancing their competitive business advantage. SaysDawes,‘Hundreds of enterprises have joined, or have made commitments to join, the DNV’s Simon Dawes in Sydney: ‘Climate change has the potential to significantly af fect sea levels, endangering the world ’s coastal facilities. Australia is taking a leading role in the international climate change debate. ’

Challenge, and independent verification ensuresthey present a realistic forecast of emission inventories and abatement actions. Verification also enhancesthe credibility of the programme.’ Successfulverification of the Challenge will demonstrate that co-ordinated voluntar y action to reduce greenhouse emissions is possible. It will also guide future international action to better manage climate change in accordance with the Kyoto Protocol. ‘The Challenge can assist in the development of structures and processesto support national reporting and the Kyoto flexibility mechanisms– sequestration, clean development, joint implementation and emissions trading, ’ says Dawes. As part of the Greenhouse Challengeagreements, all participants agreed that their reports will from time to time be subject to verification. Challengers will be randomly selectedfor future verification. Another key role for DNV is to ensure that the latest international experience in the field is available to both participants and the programme management. DNV has wide practical experience in this field.

Challengers volunteering to be part of the initial group to be verified will benefit by being acknowledged as leaders in verification of emissions inventories in the Greenhouse Challenge, and by having the opportunity to assistin fine-tuning the verification process. The independent verification process is all about increasing credibility of the Greenhouse Challengeprogramme and building the capacity of both industr y and government to report emissions inventories. Enterprises accepting the invitation to participate are from sectors as diverse as electricity, government, mining, manufacturing, oil and gas and commercial services.They represent a good crosssection of business,and a significant proportion of Australia’s greenhouse emissions. Successful verification of the co-operative agreements and progressreports of these enterprises will make a strong statement about the effectiveness of self reports and voluntary programmes.

OFFSHORE INDUSTRY

Planning for FPSOs in the

GULF OF MEXICO The Minerals Management Service, a US federal agency, has prepared an environmental assessment on operations in the deepwater areas of the Gulf of Mexico Outer Continental Shelf. An integral part of this assessment involves DNV’s risk-analysis work, which forms part of an environmental impact statement on the possible use of floating production, storage and offloading (FPSO) units.

IN SUMMARY • Over the past few years, there has been a surge in deepwater activities in the Gulf of Mexico. • With the move into deepwater comes a new set of challenges for both governmental authorities and the oil and gas industry. • Regulatory and environmental issues associated with FPSO operations in the Gulf of Mexico are high on the agenda for the Minerals Management Service, the U.S. Federal agency which manages more than a billion offshore acres and collected about US$ 4 billion in mineral revenues last year.

A

dvancesin deepwater technology have resulted in a new era of development potential for the U.S. Outer Continental Shelf (OCS), which includes the Gulf of Mexico, one of the world’s principal offshore oil and gas basins. The move into deepwater means new challenges for both the Minerals Management Service (MMS) and the oil and gasindustry. According to Chris Oynes, Regional Director, Gulf of Mexico OCSRegion, the MMS is working to keep up with industry initiatives, technology developments and other factors linked to deepwater activities; FPSO operation in the GoM is one area that needs further evaluation. Over the past few years, there has been a surge in deepwater exploration and drilling activities in the GoM. The sector has evolved rapidly, seeing frequent new projects and developments. SaysOynes, ‘Despite the previously low oil prices, we have had very substantial levels of explorator y drilling over the past couple of years.The reason for that is probably that companies have long-term, pre-committed contracts. There have been some 1,900 explorator y and development wells drilled to date in the deepwater areas of the GoM. That’s a lot of drilling; probably one of the untold stories is that as it has proceeded, the geology has revealed new frontier areas, particularly in ultra deepwaters.’

Planning ahead for FPSOs

The Shell-operated Ursa tension leg platfor m is located in 3,800 feet of water at Missisippi Canyon Block 809, oximately appr 130 miles southeast of New Orleans. This is thethfour tension leg platfor m installed and operated by Shell in the deepwater Gulf of Mexico.

DNV FORUM NO. 2/2000

The MMS’s experience of FPSO-typevesselsis limited to a single application in the Pacific Outer Continental Shelf Region. According to Oynes, no operator has proposed an FPSO as a development strategy for the GoM to date, although several have indicated that they are close to making a formal submission. SaysOynes, ‘Since we have not had an application for an FPSO formally presented to us, we have not had a concrete opportunity to work through what the specific issuesmight be on an FPSO, nor the issuesfor a particular site. Essentially, what we have today is our anticipation of the fact that we are going to get an application; the question is how do we get our regulatory house in order so that we can deal with that application.


OFFSHORE INDUSTRY ‘From an environmental perspective, there are specific issues and potential impacts related to FPSOs,as well as some broader concerns. Consequently, we decided that the proper path was to conduct an environmental impact statement (EIS). This is particularly important as it helps to address the broader and generic types of questions that will often be raised, since it would involve the first FPSO-baseddevelopment project on the GoM OCS.’

‘With the move into deepwater comes a new set of challenges for both the authorities and the oil and gas industry’ - Chris Oynes DNV is part of the team chosen by the MMS to prepare the EIS. DNV conducted the risk-analysisportion of the EIS. The study assesses the environmental effects of FPSOsby examining a hypothetical 1 million barrel storageFPSO,with tankers periodically offloading produced oil. A high-case scenario with a 2.3 million barrel storage unit has also been studied. The MMS will manage the contract and retain overall responsibility for compliance with the National Environmental Policy Act, which is the U.S. law regulating environmental issues.

The regulatory approach Regarding regulator y issues,the MMS has had to adapt some areasof the regulator y programme and responsibilities to address the different issues and concerns related to FPSOs. Explains Oynes, ‘While we’ve had a lot of discussion in many different forums on the regulator y front, we haven’t seena crystallised focus yet; now we are at a point where that is rapidly taking shape. During the next couple of months, we expect to start talking much more about the important issues that need to come into place. Right now, the regulatory approach continues to evolve, and we are tr ying to get this on some parallel path, so that in several months time we hope that our regulations and the final EIS will emerge together. Then we’ll be ready for business when some operator files an application.’

‘There are specific environmental issues and potential impacts related to FPSOs that call for an environmental impact study’ - Chris Oynes The MMS is attempting to keep up with technological advances and issues seriously affecting safe, pollution-free exploration and development offshore. According to James Regg, Chief Technical and Operations Support Section, FPSO issueshave been discussedwith operators, contractors and others for some years,and investigations are continuing into the international efforts focusing on inter faces between the production and

non-production processes.Deborah Cranswik, environmental scientist at MMS, also points out that another key issue will be the U.S.Coast Guard role in regulating FPSO operations. It should be possible to identify and co-ordinate the jurisdictional overlaps between the MMS and USCG in order to avoid dupli cation. The question of whether the FPSOsshould be doublehulled, and the applicability of OPA regulations to FPSOoperations, are also the subject of discussion.

Projections for 2000 Oil and gasproducers in the GoM are projected to drill a total of 994 wells in the year 2000, based upon an evaluation of producers’ drilling budgets and the relative stability of oil and gas prices. The full application of floating production units is uncertain, but market sourcesbelieve it is only a matter of time before FPSOs are working in the Gulf. Oynes comments, ‘We encourage operators considering the FPSO option for field developments in the GoM to come in and talk with the MMS early. However, we are concerned about the move towards ‘‘fast-track’’ development to reduce cycle time and bring for ward the date of first oil, particularly in relation to the quality and safetyof the systemsdeveloped for production on the OCS. ‘Operators need to understand that there are environmental reviewsand regulatory requirements that cannot be compromised as part of the fast-tracking effort. It will continue to be the operator ’s responsibility to demonstrate to us that the FPSO can operate in the Gulf of Mexico in a safe and pollution-free manner.’ Stuart Brewer

Enhancing safety, reducing costs in

DEEPWATER DRILLING IN SUMMARY • The task of classification societies is changing as the role of safety on offshore installations becomes ever more regulated and competitive • Many societies now offer clients a wide range of services: from life-cycle risk management and integrity management to safety, environmental and human-factor consultancy • DNV is also actively developing new and existing services such as its Failure Mode and Effects Analysis tool, which is being used by, among others, R&B Falcon Drilling as described in this article

Failures do not just happen: there is almost always an identifiable- and so avoidable - cause. Roderick J. Allan, Vice President Engineering and Technical Services, R&B Falcon Drilling, believes a focused analysis of risk could not only improve offshore safety dramatically, but also save considerable sums of money.

T

wo years ago, DNV Houston developed its Failure Mode and Effects Analysis (FMEA) system.The project waslaunched to help offshore and process-plant

operators improve safetyand reliability management, by making it easier to identify why and how failures happen and so prevent them from recurring. The systemis now available and being used by, among others, Houston-based R&B Falcon Drilling, one of the world’s largest offshore drilling contractors serving the oil and gas industry. Says Allan, ‘Consequenceof failure is the major risk we face today, especiallyregarding our deepwater activities. Typically, larger investments in this new generation of advanced vesselsmeans greater consequencesin the event of failure. One does not normally place an emphasison such problems with proven technology units, since these risks havebeen well understood and the consequences can be remedied through experience. ’ One of R&B Falcon’s major goals for the year 2000 is to eliminate equipment failures, which can produce unacceptable results. As drilling moves into ultra-deep waters, the company is acutely aware of the fact that it may only take a small, seemingly inconsequential failure of a piece of equipment to cause a major incident. The company’s intention this year is to expand the use of proven methodologies, such as FMEA, and to apply them to its critical systemsto minimise the possibility of recurrence of such a failure that may causemajor damage or systemfailure, such as that on the Deepwater Pathfinder last year.

Minimising risk The Deepwater Pathfinder, a dynamically positioned drillship, suffered loss of braking capacity to its drawworks causedby contamination of the brakepads. DNV wascalled in to undertake a root cause analysisand FMEA. Allan explains, ‘Through new design and maintenance processes,we have minimised the risk of this happening again. We have made presentations to other operators to show them what the problem wasand how it’s not going to happen again. We intend to use this information to work with other operators and contractors who own or operate similar equipment. It makesa lot of senseto prevent it Roderick J. Allan, Viceesident Pr Engineering and echnical T Ser vices, R&B Falcon Drilling Inc. Houston.

Deepwater Pathfinder is designed for operations in water depths up to10,000 ft. It is in its second year of service in the Gulf of Mexico.

Isolating failure sources ‘People look at this as a way to create redundancy in a system, so that if a failure occurs, some of the human element is taken out of the equation. In many cases,one can go back and look at existing systems,even if the systemand equipment are fairly new. Our approach is to identify the operations with the greatest risk of failure and analysethe systems,equipment and personnel to minimise the risk. This is very similar to assessments we have used in the North Sea. The process is nearly identical. ’

identifying the most likely potential failures, designers can minimise the consequences of those failures.

The company conducts drilling operations in three main market segments:deepwater, offshore shallow water and transition-zone

‘For example,’ explains Allan, ‘if there are 20 single-point failures, and 18 of them can be eradicated for just a fraction of the cost of putting in a new system,then this is a wise,cost-effectivedecision. We believe the cost of conducting these analysesis very reasonable compared to the potential cost of the failure itself. The cost consequencesof seemingly small item failures can easily run into tens of millions of dollars. ’

The units under construction will enhance the company’s leading position in the emerging ultra-deepwater market, providing drilling capability in waters as deep as 10,000 ft.

Allan points out that in many casesthe issueto be remedied is not so much technical as procedural. ‘Proper training and contingency for failures are also extremely important, so riskbasedanalysisleads us to adopt various philosophies within the company: maintenance and training, as well as the procedural

IRAN: DRY CARGO SHIPPING

Meeting challenges to THE DRY-CARGO FLEET ‘Professional and cost-effective management of our operations is our main challenge,’ says chairman and managing director of Islamic Republic of Iran Shipping Lines (IRISL) Ahad Mohammadi. Potential growth in Iranian exports of non-oil cargoes offers opportunities for IRISL, which today is Iran’s largest drycargo shipping company.

A

had Mohammadi, who is also Advisor to Iran ’s Minister of Commerce, points to the fact that low

oil prices in the late 1990sforced Iran to focus on lines of businessoutside the oil and gassector. The recovery in oil prices, saysMohammadi, has stabilised the economy, and put the countr y in a better position to make and sell products other than crude oil. ‘This represents potential growth for IRISL. Today the total annual import of dr y commodities to Iran is 16 mil lion tons, while exports are about 5 million tons. The planned increase in export of petrochemicals from the present 3.5 million tons to 10 million tons in 2002 represents a transport need that we want to meet,’ saysMohammadi, and cites a joint venture between IRISL and Iranian

‘Take the International SafetyManagement Code (ISM), for example. Its approach has not been of much help to us. We have to addressproblems from the cultural aspects also. In European companies, feedback on required improvements is accepted and often implemented without strong reactions.

SAFETY CASE REGIME

DNV leads development of PROCESS INDUSTRY SAFETY DNV is playing a leading role in processindustry safety developments in Victoria, Australia. Following an explosion at Esso’s Longford Gas Plant in 1998, Victorian industry must demonstrate high standards of safe operation through the proposed new Major Hazard Facilities Regulations, which employ the performance-based safety case approach rather than prescription. DNV is helping both the regulator and process operators to meet the new challenge.

I

n September 1998 an exchanger at Esso’s Longford facility in Australia fractured, releasing

hydrocarbon vapours and liquid. Explosions and the fire that followed killed two and injured eight, and terminated gas supply to users in Melbourne and throughout the state of Victoria. This brought many Victorian businessesto a standstill and caused a loss of public services for several weeks.Essois facing legal proceedings and compensation claims of around A$1 billion.

Technical support to Royal Commission A Royal Commission wasset up to investigate the accident, to which DNV was asked to provide technical support. The technical investigation lasted six months and took 10 man-yearsof effort (a third by DNV). The DNV team, which wascomposed of highly qualified risk engineers from Australia, Singapore, U.S.A., the U.K. and Malaysia,worked intensively on every aspect of the accident and its causes.SaysDNV Melbourne ’s Dr Luke Chippindall,

NEWBUILDINGS IN CHINA

300,000dwt tankers contract highlights CHINA´S DRIVE FOR THE WEST Established in 1990, Dalian New Shipyard is the major focus for China’s colossal investment in modern newbuilding capacity - 1.25 billion dollars per year - in the nation’s aim to become the world’s leading shipbuilder. One result of that investment is Dalian’s new 80m wide building dock, opened in 1996 and now being used to build five DNV-classed, 300,000dwt VLCCs for Iran.

NV has worked closely with Hong Kong based global carrier Orient Overseas Container Line for many years,to improve the company’s work on safety, quality

All our ships have now been brought up to level seven of its ten levels. ’ OOCL started systematicwork to improve the safety of its fleet and crews in 1993. Prior to that, various methods had been used on different ships. OOCL achieved positive results almost immediately, with a decreaseof 92.5% in days lost in 1993 when compared to 1992. Other factors indicate the same trend. ‘The IMSRS has been a useful tool for improving our safetyand routines on board,’ explains Liaw. ‘The reduced insurance costs- for the hull and machinery, for example – show that we’ve succeeded. They ’ re now only a fraction of what they were in 1993.

Huntsman Polyurethanes is aiming to win the European Quality Award, presented annually by the European Foundation for Quality Management. Huntsman has benefited greatly from DNV’s International Quality Rating System in its work of improving quality. rime benefit of using DNV’s International Quality Rating System,IQRS, lies in the rapid feedback,’ says John A. Darby, Business Excellence Manager in Huntsman Polyurethanes’ (formerly ICI Polyurethanes) Region for Europe, Africa and the Middle East. ‘ While it takes three months to prepare the documentation for the quality award – and a further six months to receive feedback - the IQRS gives us the answers at the end of a week’s assessmentwork. We achieved Level 5 in the IQRS and an EFQM score of 525 - so IQRS was accurately calibrated. ’

‘P

ment. We achieve a lower score in other areaswhere we know we can improve. Everyone can get better, and we are putting our efforts into those areas where there is most to be gained. ‘That way, we will also have other companies in the Huntsman group to compare ourselveswith. We can learn from them and they can learn from us. We can share best practices. Many units don’t know at present whether what they do is best practice. We want to avoid every site in the organisation reinventing the wheel, and wasting valuable resources. ’

DNV has broken the criteria for the European Quality Award down into some nine hundred specific questions – instead of 35 broad issues.Most questions call for a clear-cut ‘ yes’ or ‘ no’ or, for example: how many? or how often? Specific questions that give specific answers.

Seek independent audit

‘This year we expect to achieve the same benefit from using IQRS as we did last year from applying for the European Quality Award. The IQRS enables us to track our progress year by year, and we’re also told of clear areaswhere we must improve in order to win the fight for the European Quality Award,’ emphasises Darby.

Automotive industry the most demanding Huntsman Polyurethanes,of which ICI still owns 30 per cent, is a part of the Huntsman Corporation - the largest privately held chemical company in the world. The company works closely with a number of partners. The Global Polyurethanes market has shown significantly higher than GDP growth for the past 20 years,and the company cooperates closely with its customers in creating this market demand. In 1999 Huntsman came 15th among the large companies which applied for the European Quality Award. Thirteen of the applicants reached the finals, which were dominated by electronics, telecommunications and automotive firms. ‘Of our customers, those in the automotive industr y are the most demanding,’ Darby believes.‘This industr y changes quickly and demands a full insight into both technology and economics. So it ’s also satisfactory to seethat it is our automotive team which achieves the highest score in our IQRS assessments.These people are used to being tested and to working on continuous improve-

John Darby stressesthe importance of the DNV’s IQRS as a good self-assessment tool – with independent auditors trained by DNV. ‘Internal surveysare a poor wayof measuring employee satisfaction.We can seefrom our own surveysthat the degree of satisfaction varies from countr y to countr y. Internally , this may give causefor concern, but the way in which we now measure and use external benchmarking specialistsmeans that we can compare our results with those of similar companies elsewhere. Theseoften showthat the resultsare in line with the trend in that countr y – and not something that is particular to Huntsman. ‘New products are under development continuously - in fact about 60 per cent of Huntsman Polyurethanes’ hundreds of products are lessthan two yearsold. All the new products are given a new name – and we have a very disciplined introduction system. We particularly want our technical people to be close to the customer. We often know our customers’ production processes as well as they do themselves. Our German factory in Deggendorf is situated near the BMW car manufacturing plants, we’re close to the Clark’s shoe company in Somerset in England, and to Whirlpool in Italy. We also benchmark Huntsman against our competitors including Dow, BASF and Bayer .’ Recycling is another area to which Huntsman Polyurethanes is making a contribution. Wastefrom sawmillsis used to produce boards, and provide better utilisation of the forests. Old newspapers and old car tyres are recycled. New technology is also being developed to allow recycling of the polyurethane foam itself. ‘All these are important for a company seeking to demonstrate its quality credentials,’ says John Darby .

Midttun, 44, has been CEO of telecommunications company Stento AS since 1996. He holds an M.Sc. degree in economics from the Nor wegian School of Economics and BusinessAdministration in Bergen, and hasexperience in both the oil and shipping industries. His previous appointments include financial manager of Schlumberger Scandinavia, financial director of telecoms company ScanvestRing AS, and group director of Rieber & Son AS. He has also been a board member of Statoil. ‘I am convinced’, he says,‘that DNV’s work in protecting core valuessuch aslife, property and the environment will be more and more important in the future. ’

NOK 208 million profit DNV made a preliminary net profit after tax and financial items of NOK 208 million last year. Its turnover grew by NOK 200 million to NOK 4,629 million. At the end of 1999, DNV’s equity wasNOK 2.160 million, an increase of NOK 202 million on the year before. Det Norske Veritas had 5,500 employeesat the year-end, an increase of 800 on the previous year. The strong rise in the number of employeeswasdue to the acquisition of SAQ, a Swedishcertification and inspection company with 700 employees.This company was purchased from the Swedish State for NOK 280 million. CEO SvenUllring explains, ‘We have implemented long-term restructuring actions in the UK, Germany and Sweden.These costsare included in the preliminar y year-end accounts. We would have reached the low casescenario of 205 million NOK in operating profit if it had not been for this additional restructuring. ’ The yield from financial items made a contribution of NOK 136 million, which represents a 42 per cent rate of return on the capital administered. The high financial yield and lower taxes than expected compensate for the reduced operating revenues. At the end of 1999, 15 per cent of the world fleet in tonnage terms was classedby Det Norske Veritas, compared with 14.7 per cent the previous year. Of the newbuildings contracted worldwide, 17 per cent will be built to DNV class.More than 80 per cent of the world’s ships are built in Asia. China, in particular, has increased its share of the world’s shipbuilding sector, and around 30 per cent of all the ships built in China are to DNV class. In accredited quality systemcertification (ISO 9000), DNV has increased its share by 25 per cent over the past year, and is now one of the three largest certification bodies in the world.

Sharper focus and faster decisions ‘Sharper focus on our most important markets and an ability to make decisions faster are two of the improvements we hope to achieve through re-organisation,’ says Sven Ullring. The new structure will also result in stronger global management and coordination. Three business areas, each with global responsibility for development and profitability within their lines of business,headed by Chief Operating Officers (COOs), are main elements of the new organisational structure approved by DNV’s Board at its meeting last December. The changestook effect from 1 January. The regions are to be DNV’s highest operating level, and the geographical divisions will be phased out.

Three Business Areas Maritime Industr y (MI) will be headed by Tom Virik, the present head of Division Asia Pacific. Oil, Gasand ProcessIndustries (OGPI) will be headed by Henrik Madsen, the present head of Division Nordic Countries. General Industr y (GI) will be headed by Miklos Konkoly-Thege, the present head of Business Areas. The three new businessareaswill have global responsibility for developing their lines of businessand for the global profitability of their activities. The regions are responsible for all operations that take place within them, including the profitability of their activities. In addition to activities within the three businessareas,all regions are encouraged to initiate local activities and business based on local needs.

‘We met part of the 1999 boom in new orders for bulk carriers and have been able to win an increased share of the newbuilding market,’ says Hans Viig, manager of the Bulk2000 project.

DNV has established a company, IPRM AS - Integrated Petroleum Risk Management - as a 50/50 joint venture with IPRES International Ltd.

DNV’s share of the world’s bulk-carrier newbuilding orders has more than doubled over the past year, from a total share of 7.6 % of the order book at year-end 1998 to 18.2% of new orders during 1999. ‘We have gained Scandinavian, Greek and Japaneseowners, and done well at Chinese yards,’ saysViig. ‘And we have secured three newbuilding contracts on bulk carriers ordered by Japanese owners at Japanese yards. ’ The Bulk2000 project is a market initiative that started early last year with the aim of increasing DNV’s share of the world’s bulk-carrier fleet.

The West Coast Main Line runs from London's Euston station to Scotland, while other routes criss-cross the country. The railways are becoming an important business area for DNV in the U.K.

Lead for Harwich Haven The Harwich Haven Authority on England’s east coast is the first harbour authority in Europe to receive certification to DNV’s Rules for Pilot Organisations. This new standard from DNV covers many of the safetyand environmental aspectsof pilotage which are at the forefront of the U.K.’s draft Port Marine SafetyCode. The governments’srecent pilotage review came about as a result of the grounding of the SeaEmpress at Milford Haven in 1996. Speaking at the certificate presentation ceremony in London, DNV’s Senior Vice President Tor-Christian Mathiesen said, ‘I see such certification as an important milestone in our efforts to achieve a safety culture throughout the maritime industr y. A safety culture means that we can alwaysimprove. It is thus about attitudes, beliefs and values.’ DNV’s Rules for Pilot Organisations go beyond the draft SafetyCode in that they also in clude quality management issues. Har wich Haven Authority is the conservancy and pilotage authority serving the ports of Felixstowe, Har wich, Ipswich and Mistley. The Authority has within its area a number of environmentally sensitive Sites of Special Scientific Interest and Special Areas for Conservation.

QUALITY SYSTEM CHANGES This year will see the publication of ISO 9000: 2000. There are some significant changes and opportunities for improvement in the new version of the standard. Will this have a beneficial impact on companies who use it?

A customer-focused organisation will be needed to give rise to sustained customer satisfaction, with successbeing measured.

THE SEA OF CHANGE

Classification societies’ offshore role must adapt as the safety of offshore installations becomes ever more regulated and competitive. Many societies now offer clients a wide range of relevant services: from life-cycle risk management and integrity management to safety, environmental and human-factor consultancy. In this issue of DNV Forum, we look at how Det Norske Veritas is reacting to the new challenges, particularly in the promising deepwater sector.
