Safety and health in the construction of fixed offshore installations in the petroleum industry
A meeting convened by the ILO (International Labor Office) on safety problems in the offshore petroleum industry recommended the preparation of a code of practice setting out standards for safety and health during the construction of fixed offshore installations. Such a code, to be prepared by the ILO in co-operation with other bodies, including the Inter-Governmental Maritime Consultative Organisation (IMCO), was to take into consideration existing standards applicable to offshore construction activities and to supplement the ILO codes of practice on safety and health in building and civil engineering work, shipbuilding and ship repairing.

Technology trends, energy prices affect worldwide rig activity
1995-01-01
The major worldwide offshore rig markets have improved slightly this year, while the onshore markets generally lagged slightly. Offshore rig utilization rates have remained strong worldwide, with some areas reaching nearly 100%. Total worldwide offshore rig (jack ups, semisubmersible, drillships, submersibles, and barges) utilization was about 86%. Offshore drilling activity is driven primarily by oil and natural gas price expectations. Natural gas prices tend to drive North American offshore drilling activity, including the shallow waters in the Gulf of Mexico. International offshore drilling activity and deepwater projects in the Gulf of Mexico are more closely tied to oil prices. The paper discusses US rig count, directional drilling activity, jack up rig demand, semisubmersibles demand, rig replacement costs, and new construction

Judging defect severity on offshore pipelines
1982-05-24
In spite of the great care taken in manufacturing, installing, and protecting offshore pipelines, defects often occur and a few have caused pipeline failures. Criteria and methods for assessing the severity of pipeline defects are well known, but their application to offshore lines calls for extra considerations. Defects can arise during pipe fabrication or pipelaying; they can also result from mechanical damage, internal and external corrosion, and mud slides. An offshore operator will rarely need to apply a criterion for determining whether to repair or remove a defect; however, when such a criterion would be useful, it should be modified to take advantage of the external pressure provided by the seawater.

The development in this area results in new ideas, questions and research proposals. Such a new topic is, hydrogen production using offshore wind farms.
Role of Corporate-Wide Offshoring Strategy on Offshoring Drivers, Risks and Performance
2010-01-01
In this study we investigate the role of corporate offshoring strategy on offshoring decisions and performance. Based on 876 offshoring projects from 226 companies obtained by means of surveys conducted in the USA and Europe, we examine the effect of offshoring strategy on factors influencing firms' views of offshoring, and the effect of offshoring strategy on offshoring performance. Separate analyses were conducted for US and European companies in order to explore any regional heterogeneity in offshoring. A comparative analysis between companies with and without an offshoring strategy reveals that when making offshoring decisions, the former consider a broader range of factors (drivers, risks and locations) as important compared to companies without an offshoring strategy, suggesting asso...

Industrial opportunities - offshore
1998-09-01
Industrial opportunities available in the Canadian offshore petroleum industry are discussed. Oil has been produced offshore from Nova Scotia since 1992, and offshore from Newfoundland since 1997. Special needs that must be addressed in offshore operations in eastern Canada such as the cold North Atlantic environment, isolation, logistics, safety, and quality assurance, are examined. The most obvious opportunities lie with the designing, building and installing the facilities needed to extract oil and gas from beneath the sea floor and transport it to market. However, there are also opportunities in designing and fabricating clothing, customized food containers and other equipment for offshore needs. Short term opportunities also exist in the decommissioning of depleted production fields and their facilities. One of the greatest obstacles facing new entrants into the offshore oil and gas industry is the lack of a track record. To meet this challenge, the ability to seek out partners to pursue local and international opportunities through joint ventures, strategic alliances and technology sharing partnering arrangements is of great importance. It may be the difference between success and failure. 6 figs.

Offshore oil and gas : a community development perspective
2003-01-01
A community perspective on offshore oil and gas development in British Columbia was presented. It was noted that local benefits depend greatly on the level of regulation and government intervention in the industry. Community preparedness, jurisdictional certainty and corporate ethics also play a vital role. It is also necessary to clearly understand legal, economic, environmental, social and industrial aspects of offshore development. Jurisdictional concerns include the International Free Trade Agreement, ambiguities over mineral rights, and claims by First Nations to seabed and ocean resources. It was emphasized that the impact of offshore development on ecotourism and fisheries should not be underestimated. Community-based planning is critical. Economic imperatives include international prices, recovery costs, distribution of royalties, and alternative ...

Nonlinear ultimate strength analysis of fixed offshore platforms for earthquake environments
1995-12-01
The design of an offshore platform usually requires the use of ASME B31.3 and API (American Petroleum Institute) RP 2A design codes. ASME B31.3 addresses the design of pressure piping systems for offshore facilities while API RP 2A ``Recommended Practice for Planning, Designing and Constructing Fixed Offshore Platforms`` (WSD or LRFD) addresses the structural design. This paper first identifies the difference between the ASME B31.3 and API RP 2A on the earthquake load requirements. Second, the paper presents a nonlinear static pushover analysis of a typical fixed offshore platform subject to a ductility level earthquake in 394 ft (120 m) of water depth. The analysis uses a three-dimensional structural model consisting of STRUT, BEAM-COLUMN and LINEAR BEAM elements to determine the structural response while properly accounting for structure-pile-soil interaction effort. Finally, the status of current on-going efforts to implement the API RP 2A code (LRFD version) to the ISO code (International Organization for Standardization), particularly on the earthquake resistant design aspect of fixed offshore the platforms, is briefly reported.
Offshore outsourcing of services: An evolutionary perspective
2009-01-01
Offshore outsourcing is gaining increasing importance and attention in both theory and practice. The purpose of this research is to use nine in-depth case studies to analyze the evolution of offshore services outsourcing with regard to how expectations and governance structures change over time. Five testable propositions are presented, building on institutional theory, transaction cost, and resource-based perspectives. The cases demonstrate that offshore outsourcing is initiated because of increasing internal and external pressure to conform and reduce costs. Moreover, companies "chase" efficiency improvements in other geographic locations. But after reducing costs, companies discover more strategic benefits such as the potential to increase quality and market share. Importantly, as buyer...
Computational methods. [Calculation of dynamic loading to offshore platforms]
With regard to the computational methods for hydrodynamic forces, first identification of marine hydrodynamics in offshore technology is discussed. Then general computational methods, the state of the arts and uncertainty on flow problems in offshore technology in which developed, developing and undeveloped problems are categorized and future works follow. Marine hydrodynamics consists of water surface and underwater fluid dynamics. Marine hydrodynamics covers, not only hydro, but also aerodynamics such as wind load or current-wave-wind interaction, hydrodynamics such as cavitation, underwater noise, multi-phase flow such as two-phase flow in pipes or air bubble in water or surface and internal waves, and magneto-hydrodynamics such as propulsion due to super conductivity. Among them, two key words are focused on as the identification of marine hydrodynamics in offshore technology; they are free surface and vortex shedding.
A longitudinal examination of partnership governance in offshoring: A moving target
2009-01-01
The complexity of the global marketplace is driving the growth of new corporate strategies that are centered on creating "synergistic alliances in procurement, distribution, marketing, and technology". This study employs a grounded qualitative approach to investigate a growing belief that perspectives of relational governance and the resource-based view of the firm should be integrated to help explain the evolution of offshoring relationships in international marketing and supply chain settings. Specifically we ask-how well do general theories of organization correspond to governance in offshoring relationships? The premise of our longitudinal study found that offshoring relationships begin with calculative trust and opportunism, which later gives way to resource-based competency building ...

Structural integrity of offshore pipe
1998-12-31
Piping, during their design life, degrade and loose strength. The loss of strength may be due to corrosion, erosion, initial defects, fatigue or stress corrosion cracking. The defect may lead to structural failure. To improve the strength, an outer sleeve can be used. The calculation of minimum thickness of the outer sleeve under given internal pressure of an offshore riser pipe is presented. Combination of bending stress and hoop stress should be below the allowable stress. The combined interaction ratio should be less than unity.

Trends of safety measures for offshore operation. Offshore sogyo ni okeru anzen taisaku no doko
1993-04-01
Trends of safety measures for offshore oil well operation were reviewed. The Cullen report, the standard of safety regulations in every country, advised 106 items for safety of offshore operation which was presented as the survey result of the Piper Alpha platform accident in England occurred in the North Sea in 1988, and furthermore advised introduction of the formal safety assessment (FSA) to assure platform safety. In the USA, the regulation for offshore operation was widely revised in 1988, and a series of further safety items was also advised after the accident in the North Sea. In England, the responsibility to platform safety was shifted to the Health and Safety Executive (HSE) based on the Cullen report, and the presentation of the safety case based on FSA is required within 1993. In Norway, the internal self-control based on concept safety evaluation (CSE) and risk assessment is required, and in Brazil, safety regulations are under discussion referring to those in England or Norway. 6 tabs.
Offshore wind turbines are designed and analyzed using comprehensive simulation codes that account for the coupled dynamics of the wind inflow, aerodynamics, elasticity, and controls of the turbine, along with the incident waves, sea current, hydrodynamics, and foundation dynamics of the support structure. This paper describes the latest findings of the code-to-code verification activities of the Offshore Code Comparison Collaboration, which operates under Subtask 2 of the International Energy Agency Wind Task 23. In the latest phase of the project, participants used an assortment of codes to model the coupled dynamic response of a 5-MW wind turbine installed on a floating spar buoy in 320 m of water. Code predictions were compared from load-case simulations selected to test different model features. The comparisons have resulted in a greater understanding of offshore floating wind turbine dynamics and modeling techniques, and better knowledge of the validity of various approximations. The lessons learned from this exercise have improved the participants' codes, thus improving the standard of offshore wind turbine modeling.

Analysis of the effect of the coastal discontinuity on near-surface flow
1998-07-01
Conditional sampling is used herein to examine the effect of fetch, stability, and surface roughness changes on wind speeds in the coastal zone. Using data from an offshore wind farm it is shown that at a distance of 1.2-1.7 km from the coast, up to a height of 20 m above the surface, differences in wind speed distributions from onshore and offshore masts are statistically significant for flow moving offshore under all stability conditions. In contrast, differences between the distribution of wind speeds at 38 and 48 m at masts located at the coast and in the coastal zone are not significant for flow moving offshore, indicating that flow at these heights is not fully adjusted to the change in surface roughness (land to sea). These findings are in accordance with calculations of the internal boundary layer (IBL) height which indicate that the IBL would frequently be below the two upper measurement heights at 1.2-1.6 km from the coast. The analyses presented here indicate that the wind speed distribution at a potential offshore wind farm site is not solely dependent on fetch (distance from the coast) but also depends on the stability climate.

Extending onshore pipeline repair to offshore steel risers with carbon-fiber reinforced composites
2010-01-01
In the last 15 years, glass fiber hoop reinforced composite systems emerged as an acceptable, successful method for repairing corroded and mechanically-damaged onshore pipelines where the primary load is internal pressure. The feasibility of extending these repairs to offshore pipes such as risers require a thorough understanding of the complex combined load profiles; overlay of significant tension, bending, internal and external pressure. Herein an innovative design based on integrated computational models and full-scale tests is presented to address the viability of reinstating capacity to offshore pipelines and risers. The experimental program was based on a collaborative test matrix developed with the participation of composite repair manufacturers. The outcome guided and led to an eas...

Offshore newcomer : world-scale megaproject spawns international-calibre skills and facilities
1997-10-01
The development of Hibernia marked the beginning of Newfoundland`s booming oil industry. The offshore platform located 300 km offshore in the Grand Banks of Newfoundland has an estimated 615 million barrels of recoverable reserves to be produced at a projected average rate of 135,000 barrels per day. Newfoundland personnel and facilities acquired much expertise during the building of the offshore facility and are ready to enter the world market for oil and gas services and supplies. Newfoundland`s biggest operations are the fabrication yards at Bull Arm and Marystown which have the capacity for steel fabrication, concrete construction, outfitting installation, hook-up and commissioning of industrial facilities. Plans are currently underway for the Terra Nova project. Newfoundland also has a strong labor force, with international calibre skills. The capacity is here, and as confidence in that capability increases, Newfoundland firms are beginning to form partnerships with international firms. 6 figs.

Maintenance activities, such as fuel-channel replacement (FCR), small-scale spacer location and relocation (SLARETTE) and primary-side steam-generator tube cleaning, require work in high-radiation fields. This may lead to appreciable radiation doses. AECL staff experience has been that these radiation doses accrue mostly from external gamma fields, with a minor internal dose component from the uptake of tritiated waste vapour. There are no significant uptakes of other radionuclides. AECL practice for SLARETTE and FCR work at off-shore CANDU stations has been to equip AECL personnel with 1 set of thermoluminescent dosimeters (TLDs) and 1 direct-reading personal alarming dosimeter (PAD). These TLDs are read at the Chalk River Laboratories of AECL. In addition, off-shore site radiation protection personnel issue AECL personnel with a TLD. This TLD is subsequently read at the off-shore site. Consequently, there are often three independent measurements of dose from external fields for AECL personnel. Internal dose assessments rely on off-shore radiation protection personnel. All off-shore CANDU stations use urine bioassay methods for tritiated water uptakes. Most off-shore CANDU sites also have lung or whole-body gamma spectrometry capabilities or both, which, if necessary, can be used to assess doses from uptakes of gamma-emitting airborne contaminants (e.g., from {sup 60} Co, {sup 95}Zr, {sup 95}Nb, etc.). This paper discusses some internal and external dosimetry data for AECL personnel involved in recent FCR and SLARETTE work at off-shore CANDU stations. The data show that the whole-body dose contribution from uptake of tritiated heavy water is small. The data also show that three independent external dosimetry systems give dose results that are in relatively close agreement. Such information is invaluable in promoting confidence in the various dosimetry systems used under field conditions and allows Sheridan Park Health Physics staff to address any spurious measurements. The dosimetry data are also useful in planning future maintenance work. (author)

Reliability-based optimisation (RBO) is a powerful tool for including uncertainties in the optimisation process, in which structural and reliability analyses and optimisation algorithms based on mathematical or evolutionary computation concepts have to be combined effectively. This process is rather complicated and difficult to carry out for large structural systems such as steel offshore structures. In this paper, a calculation system of integrated algorithms for the RBO of the offshore towers is presented. The calculation process is composed of a structural analysis package (SAPOS) based on the finite element method, a reliability analysis program based on the first-order reliability method and an optimisation program based on sequential quadratic programming using the International Math...

Leveraging Offshoring: The Identification of New Business Opportunities in International Settings
2010-01-01
This work aims to shed light on the process through which small and medium-sized enterprises (SMEs) identify new business opportunities within their ongoing offshoring activities. Empirical evidence is drawn on the case of think3, an Italian medium-sized software company that has been offshoring its R&D activities to Bangalore, India, since the year 2000. In 2004, the company started a brand new “global” business: from selling software solutions for computer-aided design, it began selling the engineering capabilities to use its solutions, leveraging highly qualified Indian mechanical engineers. Our analysis underlines three elements underpinning think3's ability in envisaging a new profitable business opportunity. These are its experiential knowledge of: (a) the markets,...

Device for mooring a floating installation to an anchored offshore installation
1982-11-23
The device is made up of a connecting arm provided with rollers which bears on a cylindrical portion of the outer wall of the anchored offshore installation. Belts encircling this installation and the rollers are stretched to press these rollers against the cylindrical surface and permit rotation of the arm relative to the offshore installation.
Current trends in offshore technology
1994-12-31
Although this is a technical symposium concerning advances in the technology of producing oil and gas offshore, a keynote address would not be complete without mentioning non-technical factors which are extremely important for the business of producing oil and gas offshore. These are political factors and economic factors. Offshore operations are an easy target for political forces that are opposed to marine operations involving the production and transfer of hydrocarbons. For example, the oil pollution act of 1990 was a reaction to the Exxon Valdez grounding in Alaska and this act has added significantly to the risk and cost of operating offshore. Another example of this is that it is becoming more and more difficult to dispose of produced water offshore. Producing oil and gas offshore is a business that competes with other energy sources such as coal and oil and gas from wells on land. The offshore oil can only compete with these other resources by providing the same product at a competitive price. Since offshore operations are inherently more costly than land operations, the offshore oil field or gas field must be significantly larger than a land field in order to be produced. Also the offshore oil field or gas field is more susceptible to environmental risks from weather. On a more positive note, there are technical developments which are taking place and have continuously taken place to make offshore oil and gas both more economic and safer to produce. These developments are briefly discussed.
CHEMICAL COMPOSITION OF PRODUCED WATER AT SOME OFFSHORE OIL PLATFORMS
The effectiveness of produced water treatment was briefly studied in offshore oil and gas extraction operations in Cook Inlet, Alaska, and the Gulf of Mexico. Three offshore oil extraction facilities were examined in the Cook Inlet production field, and seven platforms were studi...

Offshore nuclear power plants--spectacle or spectre
The nuclear power industry is about to moor a chain of barge-mounted nuclear power plants to the sea floor, only a short distance offshore, in the regions of rapidly increasing electrical demand. Buried in the seabed, ultra-high voltage oil-insulated cables will link these offshore power plants to regional power grids. This paper considers the origin of the offshore move, examines the status of the fledgling offshore power industry, determines the legal regime of offshore nuclear power plants and ruminates upon the social cost of this newest hegira.

A joint location and outsourcing sustainability analysis for a strategic offshoring decision
2010-01-01
With economic globalisation and the emergence of extended enterprises derived from interrelationships among organisations, there has been a steady increase in offshore outsourcing activities. Subsequently, the strategic importance of offshoring decisions is important. Traditional offshoring decisions mainly emphasise outsourcee (supplier) selection problems, with their focus upon economic factors. Sustainability, which has recently been regarded as a competitive necessity in most industries, rarely enters into the modelling or discussion. Furthermore, additional and integrated facility location factors need to be included into the offshoring decision process. To help integrate these factors and concerns, this paper constructs a model for evaluation and selection of various offshoring alter...

This paper investigates how the global orientation of top management and their ability to manage partnerrelationships impact on the performance of offshore service providers (OSP) in the IT sector. Based on a sample of 68 offshore IT service providers in India, the results suggest that although individually both global orientation of top management and relationship management contribute positively to the performance of OSPs, firms with higher global orientation are better at managing their client relationship and perform better. The implications of the mediating effects of top management global orientation are discussed fully.

Helicopter industry prepares to meet offshore challenges
2003-06-01
Helicopter transportation plays an important role in offshore oil and natural gas exploration and production. New technology is rapidly developing. This article introduces two new heavy helicopters, the Eurocopter EC-225 and Sikorsky's S-92. The EC-225 is the next generation Super Puma; it has a range of 877 km fully loaded and almost 1,000 km with an additional fuel tank. CHC Helicopter Corporation of St. John's Newfoundland and Labrador is the launch customer of the EC-225, with delivery of this certified aircraft expected in 2004. The Sikorsky S-92 is FAA-certified, but requires additional certification and extensive de-icing testing, before it can be cleared to fly commercially. It, too, will be capable of flying more than 900 km. CHC Helicopters International, with headquarters in Vancouver, BC, is responsible for the company's offshore oil and gas operations. It has a fleet of 36 medium and heavy helicopters, providing helicopter transportation services to both onshore and offshore petroleum markets around the world. CHC is also active in Denmark and Norway, where it operates an international helicopter training centre and Europe's largest helicopter repair and overhaul centre.
Oil platform security : is Canada doing all it should?
2006-03-15
Government policies are not yet in place to protect offshore oil and gas platforms against terrorist attacks in Canada. This paper investigated the measures that several countries have taken to optimize maritime security against terrorist threats to offshore oil platforms. Security approaches adopted in Canada were then evaluated. After the terrorist attacks of 2001, the International Shipping and Port Security Code (ISPS) was established to increase the security of maritime shipping and port infrastructure. Existing and regulatory compliance programs in the United States were enhanced for offshore platform security in the form of regional and local alert systems; increased Coast Guard presence and patrol; and collaboration with other agencies to establish risk management strategies. In addition to establishing the military-led Joint Offshore Protection Command, Australia has augmented security patrols for offshore platforms and their surrounding waters. The Dutch government has increased coast guard patrols for offshore platform protection, and has created the 7 Netherlands Special Boat Squadron to address potential terrorist attacks. In Norway, special forces response unit teams have been created to support coast-line security. In response to the ISPS, Canada has created the Maritime Section of the Joint Task Force in the Special Operations Forces Command. However, security administration and emergency preparedness issues are spread across various governmental departments and agencies. Natural Resources Canada has been collaborating with federal departments, provinces and private industry to bring legislation concerning offshore platforms up to date, and a draft Memorandum to Cabinet has been prepared. 24 refs.
Offshore wind power in the US: Regulatory issues and models for regulation
2009-01-01
The first offshore wind farm became operational in 1991 in Vindeby, Denmark. By 2008, large offshore wind farms had been built in Denmark, the UK, the Netherlands, Ireland, and Sweden with a total capacity of 1200 MW. Offshore wind farms have the potential to generate a significant fraction of US electrical consumption, but the US currently lacks offshore wind farms and is still developing a regulatory system. At the state level only Texas has a leasing system for offshore wind. Since all offshore land is the property of the state and cannot be legally developed without a lease from the government, these absences have stalled development. We review and compare regulatory and leasing systems developed in Europe and the US to inform a discussion of the major issues associated with the development of an offshore leasing and regulatory system. We focus on the tradeoffs between ...

In the framework of the international agreements, the France fixed ambitious objectives of electric power production from renewable energies, and among other the wind power. THe offshore chain of this energy seems to be promising, but the first projects show difficulties, because of reluctance from other sea users, uncertainties on the projects profitability or because of the complexity of the regulatory framework. Thus an inter-departmental group has been constituted in order to discuss these problems. This report is a synthesis of their works. It analyzes the today context and proposes possible orientations.

The 1982 sinking of the offshore drill rig Ocean Ranger sparked a federal inquiry into eastern Canadian offshore operations that revealed serious inadequacies in the ability of aviation resources to respond to a major offshore incident. Since then, initiatives have been undertaken to improve aviation resources for offshore search and rescue (SAR), especially since an increase in offshore activities generated by the Hibernia and Cohasset/Panuke projects. The Rescue Coordination Center (RCC) in Halifax, Nova Scotia has been modernized to enable quick location of incidents and coordination of rescue efforts. New regulations require offshore drilling companies to have a dedicated SAR platform on standby. Research has changed from the earlier emphasis on survival equipment and planning to the active training of SAR technicians and installation of rescue equipment on aircraft. North Sea operations have been studied to improve safety on offshore support helicopters such as the Sikorsky S-61s used in the LASMO partnership working offshore near Sable Island. Private industry is contributing to offshore SAR by providing SAR capability at Yarmouth, Nova Scotia and St. John's, Newfoundland, and share information with RCC. Helicopters and crews supporting offshore exploration are now SAR-capable. 3 figs.

The 1990s are seeing the end of an era for traditionally skilled radio operators and the conventional use of terrestrial radio for Distress and Safety communications. In 1992 the implementation of the Global Maritime Distress and Safety System (GMDSS) introduced new methods of distress alerting and a new breed of radio operators predominantly combined with other functions on merchant vessels. The report looks at a number of areas, focusing on issues relevant to the carriage of Radio Operators or radio equipment on offshore installations and includes: The international and national Regulatory Structure; The Offshore Communications Infrastructure and the impact of GMDSS; The regulations applicable to offshore installations on the U.K. Continental Shelf; Radio Operator qualifications required for the full range of radio equipment; A comparison of the Norwegian and U.K. Regulatory infrastructure and Regulations; An analysis of practising Radio Operators and installation equipment fits; An analysis of Medics and the issues concerning the dual roling of the Medic with the Radio Operator function; and A review of Radio Operator competencies required offshore and any shortfalls of existing maritime and aeronautical radio operator certificates.

A review of interactions between the fishing industry and the offshore petroleum industry published by the International Council for the Exploration of the Sea reports that tests have been made on designed modifications to beam trawls and otter boards to reduce the risk of fouling that can damage the concrete casing on small pipes or can endanger a fishing vessel crew; that a Dutch investigation suggests that damage to fishing gear by fouling undersea pipelines happens only when pipe is being laid or shortly afterward when the pipeline is only partly buried or the bottom around the trench is unstable; that the Dutch Government has stipulated that in order to avoid damage by a large anchor that may penetrate 1 m into the seabed, pipelines in heavily fished areas should be covered to a depth of 2 m, something pipelaying companies have been unable to achieve in the Dutch or British sectors of the North Sea; and that oil pollution and chronic low-level discharges sometimes cause tainting of shellfish, but that off the California coast, in the Gulf of Mexico, and in the North Sea, the effects of offshore production are small.

This study is concerned with the potential for conflict and cooperation arising from the development of South-East Asia's offshore petroleum resources, within the framework of demand and supply locally and internationally. The relationship of energy to economic growth and the patterns of energy consumption in the region over the period 1963-74 are discussed. After presenting the potential for petroleum production in offshore areas of South-East Asia, the three basic sources of conflict related to offshore development are analyzed. They are the jurisdictional issues concerning the Law of the Sea and divergent national perceptions of these issues; actual territorial disputes in the South China Sea and Gulf of Thailand; and potential conflicts arising from geological and environmental factors. Some economic and other impacts of petroleum development are explained and suggested economic welfare implications of disagreement versus cooperation between the countries covered. The application of benefit and cost analysis for assessing such impacts was also outlined. The study concluded that the crucial economic policy question centers on the cost to a nation's well-being of being denied access to its petroleum resources because of protracted disagreements over ownership rights. 9 figures, 21 tables.

Majority of offshore oil development systems in Japan uses floating offshore structures. This paper describes their current status and trends. The future requirement will call for developments of marginal oil fields (those kept refrained from production because of difficulty in economic pay-off) and oil field prospecting, drilling, and production in sea areas with severer environmental conditions (areas with great water depths and polar regions). To develop marginal oil fields economically, the floating, production, storage and offloading (EPSO) system has been in operation in recent years, which consists of a turret type single point mooring (SPM) system. Each country is experiencing hardships in finding elemental technologies required for floating type offshore structures, and solving problems in building cost, social consensus, and faults. Restrictions are emerging in the U.S.A. in environmental protection aspects. Underwater line-shaped structures include a large number of problems. Experiments in this respect are planned by research project teams in Japan to launch in actual sea areas in 1993. Improved systems to be used at great water depths have been devised internationally, and have been put into practical use. 56 refs., 11 figs., 3 tabs.
BS in Naval Architecture and Marine Engineering at the University of New Orleans
"Although naval architecture and marine engineering seems to be a very specialized discipline of engineering, it is this only in the sense that its objectives are systems operating in a marine environment: ships, boats, yachts, offshore structures, submarines, etc. However, the very nature of these systems require naval architects to have a broad understanding of general engineering topics, because there is no marine system without mechanical subsystems and electrical or electronic equipment. Thus, besides the specific methods to design and analyze marine systems, naval architecture and marine engineering also comprises the integration of many different subsystems into a functional whole. The degree in Naval Architecture and Marine Engineering prepares majors for careers in the US and international shipbuilding and offshore industries by applying the principles and laws of basic sciences and mechanics to the design, construction and operation of commerical, naval, and recreational vessels as well as offshore structures and other floating systems. The University of New Orleans is one of the select few universities to offer a Bachelor of Science in Naval Architecture and Marine Engineering (NAME) degree. The program was founded in the early 1980's on initiative of the local shipbuilding and offshore industry. Since then the program has prospered and grown considerably, although Hurricane Katrina set us back momentarily in terms of student numbers."
Visual impact assessment of offshore wind farms and prior experience
2009-03-15
Energy planners have shifted their attention towards offshore wind power generation and the decision is supported by the public in general, which in the literature has a positive attitude towards offshore wind generation. However, globally only a few offshore wind farms are operating. As more wind farms start operating and more people become experienced with especially the visual impacts from offshore wind farms, the public positive attitude could change if the experienced impacts are different from the initially perceived visual interference. Using a binary logit model, the present paper investigates the relation between different levels of prior experience with visual disamenities from offshore wind farms and perception of visual impacts from offshore wind farms. The differences in prior experience are systematically controlled for sampling respondents living in the areas close to the large scale offshore wind farms Nysted and Horns Rev and by sampling the a group of respondents representing the Danish population, which has little experience with offshore wind farms. Compared to previous results in the literature, the present paper finds that perception of wind power generation is influenced by prior experience. More specifically, the results show that people with experience from offshore wind farms located far from the coast have a significant more positive perception of the visual impacts from offshore wind farms than people with experience from wind farms located closer to the coast. These results are noteworthy on two levels. First of all, the results show that perceptions of offshore wind generation are systematically significantly influenced by prior experience with offshore wind farms. Secondly, and in a policy context, the results indicate that the future acceptance of future offshore wind farms is not independent of the location of existing and new offshore wind farms. This poses for caution in relation to locating offshore wind farms too close to the coast. (author)

As from the flexibilization of the petroleum monopoly, which took place in the second half of the 1990's, the petroleum and gas sector in Brazil has undergone a series of changes that have directly impacted the commercial relations among the companies in the sector. The increases in operational efficiency and reduction of costs have become basic factors for the companies wishing to compete in this market. This paper presents a study whose objective is to map, model, and determine the costs involved in the process for internal movement in a warehouse used as logistics support to offshore petroleum production. Based on the description of the internal movement process for product storage, the main resources are identified. Then, a mathematical model based on Activity-Based Costing is draw up, in which the results generated comprise the values for internal movement costs for each type of product moved in the warehouse.

Visual impact assessment of offshore wind farms and prior experience
2009-01-01
Energy planners have shifted their attention towards offshore wind power generation and the decision is supported by the public in general, which in the literature has a positive attitude towards offshore wind generation. However, globally only a few offshore wind farms are operating. As more wind farms start operating and more people become experienced with especially the visual impacts from offshore wind farms, the public positive attitude could change if the experienced impacts are different from the initially perceived visual interference. Using a binary logit model, the present paper investigates the relation between different levels of prior experience with visual disamenities from offshore wind farms and perception of visual impacts from offshore wind farms. The differences in prior...
The offshore trend: Structural changes in the wind power sector
2009-01-01
In recent years, the wind power sector has begun to move offshore, i.e. to use space and good wind speeds on the open sea for large scale electricity generation. Offshore wind power, however, is not just technologically challenging but also a capital intensive and risky business that requires particular financial and organizational resources not all potential investors might have. We therefore address the question, what impact offshore wind power may have on ownership and organizational structures in the wind power sector. We compare on- and offshore wind park ownership in Denmark, the UK and Germany. The analysis shows that offshore wind power in all three countries is dominated by large firms, many of which are from the electricity sector. In Denmark and the UK, also investors from the gas and oil industry play an important role in the offshore wind business. This development ...

Summary Offshore production offers a new perspective for mussel aquaculture in the German Bight (North Sea) as no expansion is possible in the intertidal and subtidal zone of the Wadden Sea because of restrictions on the number of licenses. The development of offshore wind farms offers a unique opportunity because of the associated infrastructure. Service platforms, as well as the pylons themselves, offer perfect structures for mooring longlines and other culture units. One of the advantages of offshore culture may be a lower parasite load in offshore mussels compared with mussels produced under traditional inshore bottom culture. By sampling mussel spat from offshore suspended buoys or collectors, we simulated an offshore culture situation and compared parasite infestation rates with thos...
Dutch offshore suppliers in confident mood
1998-01-01
A series of linked articles discusses the current state of the Netherland's offshore industry. Reduced taxes, and availability of exploration licenses has meant that explorers and producers are drawn to the small size, but frequent yield explorations on Holland's continental shelf. The excellent operation record of Rotterdam's Verolme Botlek yard. For repair and maintenance of offshore platforms and associated plant, is explored as the facility plans to diversify into newbuilding. The construction of an offshore basin designed for the hydrodynamic testing of offshore plant intended for deepwater use is described. The Netherlands maritime research institute (Marin) aims to stay at the forefront of offshore research and development with this new facility. Other articles cover pipe tensioning, new large linear winches and innovations in offshore drilling and ...

High labor cost in western countries allows cost savings by companies engaging in IS offshoring. However, studies worldwide indicate that a large number of companies that engaged in IS offshoring are not satisfied with the outcome. Our study examined the determinants of IS offshore project success: We developed a model and empirically tested it with data collected from 304 experts who reported on projects offshored from Germany to a wide range of near and distant countries. The model posited a direct effect of offshoring expertise and trust in offshore service provider (OSP) on success, as well as an indirect effect mediated by project suitability, knowledge transfer, and liaison quality. An analysis using partial least squares (PLSs) provided significant support for almost all these relat...
DOES OFFSHORING PAY? FIRM-LEVEL EVIDENCE FROM JAPAN
2010-01-01
This article explores the impact of offshoring on productivity using firm-level data for the Japanese manufacturing industries during the period 1994-2000. We find that intrafirm offshoring, that is, sourcing of intermediate inputs to foreign affiliates within a particular multinational firm, has generally a positive effect on productivity of the offshoring firm, while arm's-length offshoring, that is, sourcing to unaffiliated foreign firms, does not have such an effect. In addition, the impact of arm's-length offshoring is negative for nonmultinationals and nonexporters but nonnegative for multinationals and exporters. These results suggest that the costs of searching foreign firms suitable for offshoring are nonnegligible. (JEL F14, L23)
Canada-Nova Scotia Offshore Petroleum Board Annual report 1998-1999

Expanding to offshore : technology perspective
2003-07-01
The offshore oil and gas industry is a $30 billion industry that is evolving rapidly with technology and which is placing heavy emphasis on safety. This Power Point presentation described some of Sandwell's experience in the offshore oil and gas development in British Columbia with particular reference to major offshore engineering projects from Vancouver. Sandwell has had past experience with projects in the Beaufort Sea, Russia, Asia and Canada. The projects include seismic engineering, artificial islands, concrete caissons, steel caissons, spray ice islands, ice roads, Hibernia's gravity base structure, Hibernia's transshipment terminal, and the Northstar sheet pile retained and slope protected island. Offshore development in British Columbia will depend on water depth, and whether the reservoirs are predominantly oil or gas. A location map of drilling in Queen Charlotte Basin was included with the presentation. The following oil field scenarios were examined: shallow water, tubular jacket type platforms, pipelines to shore, shore terminals, tanker transport to market, and alternatives to jacket platforms. It was noted that companies in British Columbia have the expertise for infrastructure design, environmental engineering, wave/coastal engineering, and engineering of basic structures. The process engineering expertise will likely come from Calgary. Offshore development will likely be implemented by large international consortia and will be traditional using proven technology. 28 figs.
Offshore regulation : number 4 of a series of papers on energy and the offshore
1998-11-01
The delicate nature of regulating offshore oil and gas developments in Canada, the result of competing issues and several jurisdictions with sometimes contradictory approaches to regulation, is reviewed. Taking Nova Scotia as the example, government permission is needed for any and all activities associated with offshore exploration and development. Specific approval procedures must be followed for seismic programs, drilling activities, the development plan, the installation of production facilities, operational procedures and diving programs. All rights to Canadian offshore oil and gas are held by the Crown. Major legislations affecting oil and gas developments in Nova Scotia`s offshore are: (1) the Canada-Nova Scotia Offshore Petroleum Resources Accord Implementation Act, (2) Canada Environmental Assessment Act, (3) Nova Scotia Offshore Area Petroleum Geophysical Operations Regulations, (4) Guidelines on Plans and Authorizations Required For Development Projects, and (5) Guidelines on the Issuance of Exploration Licences. The mission and responsibilities of the lead agency in Nova Scotia, the Canada-Nova Scotia Offshore Petroleum Board (CNSOPB) is explained. A review of the regulatory process for offshore development in the United Kingdom portion of the North Sea and the United States are also presented to illustrate the different approaches in different jurisdictions. 16 refs., 4 figs.

In response to the constant increase of the marine environment destruction, due to the exploration of its natural resources, several important international conventions have been edited since the years 60's aiming to improve the control of the pollution in the oceans. Annex IV of MARPOL 73/78 (The international Convention for the Prevention of Pollution from Ships) issued by the International Maritime Organization (IMO) entered in force in August 1st, 2005 establishing international rules for controlling the pollution caused by human sewage discharged from ships and offshore platforms. The rules established by IMO Resolutions go through constant improvements due to frequent innovations on technology, science and politics. Brazil as one of the MARPOL 73/78 Convention signatory countries, applies all the rules determined in this Convention through specific legislation. In October 2006 the IMO Marine Environment Protection Committee established the new resolution MEPC.159 (55) amending the parameters of sewage analysis and the performance tests for Sewage Treatment Units to be installed on board ships and offshore platforms from January 1st 2010, with the purpose to reduce the parameters of the pollution caused by human sewage discharge on board ships and offshore platforms.

Development of the conceptual design for FLOAT - an offshore floating wind turbine - is described in this paper. This design represents a marriage of the wind power and offshore oil and gas technology. The objective of the FLOAT project is to develop a floating wind turbine system enabling the economic generation of electricity from wind power in offshore locations, typically between 100 and 300 m water depth. The technical and economic aspect of installing an offshore wind farm based on the FLOAT concept is addressed. Issues with regard to legal, environmental, fabrication and installation operations are considered
Offshore use of the self-potential method
1976-03-01
An offshore self-potential array, towed behind a small boat, has recorded anomalies of up to --300 mV. These anomalies were related to conductive onshore deposits, and appear to be caused by offshore extensions of the deposits. Along with locating onshore deposits and their offshore extensions, the system may be useful for locating offshore deposits with no onshore extension. The background noise level of the system typically is a few tenths of a millivolt, allowing reliable recording of one millivolt gradient anomalies under average sea conditions.

Central to the question of legitimacy in the difficult issues of international taxation and confidentiality is the comity principle, which is an extension of the principle of territorial sovereignty. The real concern of onshore countries such as Australia in relation to offshore activity is often actual financial loss, rather than high or moral principles. The argument thus follows that, in response to the international pressures exerted through directives and sanctions of supranational bodies such as the OECD, all things being equal, offshore states have a similar right to safeguard their economic and political interest by upholding them.

The basic earthquake design process is outlined. Future improvements to this draft are identified, as are the challenges that lie ahead.
1999-01-01
The success of Dreco Rig Systems, a division of National Oilwell Canada Ltd., in becoming the foremost international designers and manufacturers of offshore drilling equipment is discussed. Dreco has been at the same Edmonton location since 1972, starting out as a rig mast repair shop, eventually expanding into building components such as draw-works and mud pumps and still later to full-blown drilling rigs. Following the drastic curtailment of exploration in Alberta in 1982, the company began specializing in high-end equipment for international markets for use in some of the most extreme environments in the world, including offshore, Arctic, desert and jungle terrain. Today, the Edmonton and Nisku facilities of the company subcontract 61,000 man-hours of employment per month, and turn out some 7,000 tons of fabricated steel annually. Most notable accomplishments ...

Present work shows a qualitative evaluation of an offshore degasser vessel aiming the improvement of the water processing plant capacity. For such computational fluid dynamics (CFD) allowed the analysis of the flow pattern inside the vessel for different operational flow rates and internal geometries. This vessel is responsible for the process of water final polishing to be disposed into the sea. Original capacity of the vessel is 13.308 m{sup 3}/d, but after some changes in the outlet section, the processing capacity increased to 24.000 m{sup 3}/d, without changing its separation efficiency. However, as newer production predictions state that the new processing capacity should be increased to 26.000 m{sup 3}/d, there is some uncertainty on how would be this vessel behaviour, given the new operational condition. CFD analysis will be used to evaluate the flow characteristics inside the vessel (residence time distribution), therefore providing information on the separation performance for each one of the specified conditions and internal modifications.

Offshore wind power experiences, potential and key issues for deployment
2009-01-15
Wind power has been growing at spectacular rates. Today it is the largest non-hydro renewable power technology. Worldwide there is 74 GW of installed capacity which is 1.7% of power generation capacity and in 2006 it accounted for 0.82% of electricity production. However, offshore wind still only counts for a very small amount and development has only taken place in North European counties round the North Sea and the Baltic Sea over the last 15 years. Offshore wind is still some 50% more expensive than onshore wind, but more wind resources and lesser visual impacts from larger turbines are expected to compensate for the higher installation costs in the long term. Most offshore wind farms are installed in British, Swedish and Danish waters, and present-day costs of installing wind energy in the UK are between 1,200 to 1,600 GBP/kW (1,781 to 2,375 Euro/kW) offshore, while in Sweden investment costs were 1,800 Euro/kW, and in Denmark 1,200 to 1,700 Euro/kW, though investment costs for a new wind farm are expected be in the range of 2.0 to 2.2 mill. Euro/MW for a near-shore shallow depth facility. Future developments in offshore wind technology concerning aerodynamics, structural dynamics, structural design, machine elements, electrical design and grid integration could drive investment costs from present-day range of 1.9 to 2.2 mill. Euro/MW down to 1.35 - 1.54 mill.Euro/MW in 2050, which accounts for a reduction of costs of approx. 35%. In order to sum up progress and identify future research needs, the International Energy Agency (IEA) Wind agreement Task 11 should arrange a new meeting concerning long term research needs for reviewing 'the long term strategy for 2000 to 2020' from 2001, to come up with suggestions / recommendations on how to define and proceed with, the necessary research activities of the IEA Wind Agreement and governments involved on key wind issues related to offshore technologies.

The North Sea Bird Club. Ten years of recording in the North Sea
1991-01-01
This paper reports that the creation of a club for the purpose of encouraging oil and gas workers to watch birds may not at first seem a viable proposition. To the layperson, birds offshore conjures up an image of hundreds of seagulls following fishing boats, and very little else. Also, the act of birdwatching is not seen as a typical offshore worker's activity. Anyone who has worked on an installation offshore and who has any interest in wildlife will be aware of the occasional presence of land-birds. Two decades ago, prompted by some keen offshore workers, a single oil company set up a monitoring program, which quickly became popular with a number of its employees. Birds seem offshore were recorded on data forms and collected together. At this stage the club was purely another recreation facility. However, when the data were collated it was soon realized that installations offshore ...
The Atlantic offshore experience : a regulatory perspective
2002-07-01
Some issues of interest regarding petroleum operations in the offshore areas of Nova Scotia and Newfoundland are discussed with particular emphasis on the identification of operational issues, regulations and Canadian legislation as it applies to the exploitation of offshore petroleum resources. As distinction between territorial waters and high seas evolved, two matters needed to be addressed: (1) the nature of the coastal state's rights regarding territorial waters, and (2) the extent of these waters. This paper presents an overview of the creation of the Canada-Newfoundland/Nova Scotia Accords and Accord Legislation. It also describes the provincial/federal relationships over offshore resources, and the area of jurisdiction of the Canada-Newfoundland Offshore Petroleum Board. The following regulatory issues are also outlined: (1) occupational health and safety requirements, (2) the process for development review, (3) onshore to offshore drilling, a dual jurisdiction, and (4) disclosure of information. 34 refs., 1 tab.

Preferences of coastal zone user groups regarding the siting of offshore wind farms
2009-01-01
Offshore wind power has a large potential as a vast resource for delivering clean and abundant energy on a global scale. However, the siting of offshore wind farms in the coastal zone has negative effects on the seascape. This might be particularly evident in the case if offshore wind farms are located close to areas with recreational activities in the coastal zone. Extending the analysis from a previous investigation of the preference for reducing visual impacts from offshore wind farms, the present paper utilises the same sample representing the Danish population. Based on the stated preferences from a Choice Experiment in a mail survey the preferences for reducing visual disamenities from offshore wind farms among different types of coastal zone users are compared to the preferences of ...
Paying for the Piper. Capital and labour in Britain's offshore oil industry
1996-01-01
This book makes the first serious appraisal of the current offshore safety regulatory regime instituted after Piper Alpha, and of the oil industry's attempts to contain subsequent unwelcome regulatory interference. It concludes that, as yet, offshore safety is little or not at all improved. The fraught history of trade unionism in the offshore industry and the largely successful strategies of employers to sustain a virtually union-free environment is also examined. The conflict over health and safety offshore has been inextricably bound up with the sometimes brutal struggle over union rights as the workforce has attempted to achieve a collective voice in the reform of safety and production standards. Paying for the Piper shows how the offshore unions have attempted to alter the unfavourable balance of class forces shaped by some of the world's most powerful concerns. ...

Various merits of offshore atomic power plants are illustrated, and their systems are assessed. The planning of the offshore atomic power plants in USA is reviewed, and the construction costs of the offshore plant in Japan were estimated. Air pollution problem may be solved by the offshore atomic power plants remarkably. Deep water at low temperature may be advantageously used as cooling water for condensers. Marine resources may be bred by building artificial habitats and by providing spring-up equipments. In the case of floating plants, the plant design can be standardized so that the construction costs may be reduced. The offshore plants can be classified into three systems, namely artificial island system, floating system and sea bottom-based system. The island system may be realized with the present level of civil engineering, but requires the development of technology ...
Industrial opportunities - offshore
1998-01-01
Industrial opportunities available in the Canadian offshore petroleum industry are discussed. Oil has been produced offshore from Nova Scotia since 1992, and offshore from Newfoundland since 1997. Special needs that must be addressed in offshore operations in eastern Canada such as the cold North Atlantic environment, isolation, logistics, safety, and quality assurance, are examined. The most obvious opportunities lie with the designing, building and installing the facilities needed to extract oil and gas from beneath the sea floor and transport it to market. However, there are also opportunities in designing and fabricating clothing, customized food containers and other equipment for offshore needs. Short term opportunities also exist in the decommissioning of depleted production fields and their facilities. One of the greatest obstacles facing new entrants into ...
HSE Inspectors Offshore Safety Division Handbook. Radio operator competency
1997-01-01
This Handbook is provided as a quick reference guide for HSE Offshore Safety Division Inspectors on the offshore radio communications regulatory structure and infrastructure. It outlines the impact of the Global Maritime Distress and Safety System (GMDSS) which came into force on 1 February 1992 and is due to supersede existing arrangements for maritime distress communications by 1 February 1999. The handbook provides relevant extracts from research carried out on Radio Operator Competency for the Offshore Oil and Gas Industry, as detailed in the Offshore Technology Report - ``Radio Operator Competency`` (Reference - OTO 96 045). Whilst this Handbook will be a useful reference during offshore inspections, it is recommended that the full report be referenced for a more detailed analysis of the subject of radio operator competency and emergency communications.

Specific recommendations of off-shore turbulence intensities, applicable for design purposes, are lacking in the present IEC-code. The present off-shore wind climate analysis presents the distribution of the turbulence standard deviation around the mean turbulence standard deviation, conditioned on the mean wind speed. Measured distributions, based on a huge amount of measuring data from two shallow water off-shore sites, are parameterized by fitting to a three parameter Weibull distribution. Combining a simple heuristic load model with the parameterized probability density functions of the turbulence standard deviations, an empirical off-shore design turbulence intensity is evaluated that in average yields the same fatigue damage as the distributed turbulence intensity. The proposed off-shore design turbulence intensity is, within the IEC code framework, applicable for extreme as well as for fatigue load determination. (au)
Danish offshore wind - Key environmental issues
2006-01-01
Danish experience from the past 15 years shows that offshore wind farms, if placed right, can be engineered and operated without significant damage to the marine environment and vulnerable species. The comprehensive environmental monitoring programmes of Horns Rev Offshore Wind Farm and Nysted Offshore Wind Farm confirm that, under the rieght conditions, even big wind farms pose low risk to birds, mammals and fish, even though there will be changes in the living conditions of some species by an increase in habitat heterogeneity. The monitoring also shows that appropriate siting of offshore wind farms is an essential precondition for ensuring limited impact on nature and the environment, and that careful spatial planning is necessary to avoid damaging cumulative impacts. Due consideration to limiting the impacts on nature together with positive attitudes towards offshore ...
Case study: inter-jurisdictional assessment issues in the Sable Offshore Energy Project
1999-01-01
The Sable Island Offshore Energy Project (SOEP) has as its basis the development of six natural gas fields containing 85 billion cubic m of recoverable reserves. The project consists of a number of key activities including the drilling, completion and production of offshore wells, the fabrication and installation, operation and maintenance of offshore production and processing platforms, subsea and offshore pipelines, as well as onshore natural gas and NGL processing facilities. Based on the potential level of activity, there is a need to continue to improve the regulatory review process. The lessons learned in launching the Sable Offshore Energy project are numerous and will prove beneficial to other endeavours of this nature. The unique approach the Project took to regulatory review and to public consultation was beneficial, and having SOEP and MNPP reviewed ...

Technological learning in offshore wind energy: Different roles of the government
2007-12-15
Offshore wind energy is a promising source of renewable electricity, even though its current costs prevent large-scale implementation. Technological learning has improved the technology and its economic performance already, and could result in significant further improvements. This study investigates how technological learning takes place in offshore wind energy and how technological learning is related to different policy regimes. Offshore wind energy developments in Denmark and the United Kingdom have been analysed with a technology-specific innovation systems approach. The results reveal that the dominant forms of learning are learning by doing and learning by using. At the same time, learning by interacting is crucial to achieve the necessary binding elements in the technology-specific innovation system. Generally, most learning processes were performed by self-organizing entities. However, sometimes cultural and technical barriers occurred, excluding component suppliers and knowledge institutes from the innovation system. Danish policies successfully anticipated these barriers and removed them; therefore, the Danish policies can be characterized as pro-active. British policies shaped stable conditions for learning only; therefore, they can be characterized as active. In the future, barriers could hinder learning by interacting between the oil and gas industry, the offshore wind industry and academia. Based on this study, we suggest national and international policy makers to design long-term policies to anticipate these barriers, in order to contribute to technological learning. (author)
Quantitative Comparison of the Responses of Three Floating Platforms
This report presents a comprehensive dynamic-response analysis of three offshore floating wind turbine concepts. Models were composed of one 5-MW turbine supported on land and three 5-MW turbines located offshore on a tension leg platform, a spar buoy, and a barge. A loads and stability analysis adhering to the procedures of international design standards was performed for each model using the fully coupled time-domain aero-hydro-servo-elastic design code FAST with AeroDyn and HydroDyn. The concepts are compared based on the calculated ultimate loads, fatigue loads, and instabilities. The results of this analysis will help resolve the fundamental design trade-offs between the floating-system concepts.
Overview and outlook for Maritime markets
1998-09-01
The potential of the Maritime provinces as being among the world leaders in manufacturing and value-added resource processing, low unemployment and steady economic growth was explored. Irving Oil and J.D. Irving Ltd., have actively participated in supporting the Sable Offshore Energy Project and Maritimes and Northeast Projects because of the promise of tremendous economic benefits the projects will have on the Maritime provinces. It was predicted that the projects will create thousands of jobs in Nova Scotia and New Brunswick, but more importantly, they will make the region more cost-effective and more competitive in the global markets. The Sable offshore project will allow Maritimers to compete internationally on a level playing field. With gas becoming available in the region, the opportunity exists to generate electricity at lower costs using natural gas turbines and co-generation facilities. Cheaper electricity will create new opportunities for further industrial expansion, more jobs and a stronger economy for the Maritime provinces.
Northern Australia's energy arc - North West Shelf
2000-01-01
One of the world's great sources of natural gas is promising immense opportunities for the development of feedstock for petrochemical industries. The lures for new players to Western Australia are world-class offshore natural gas fields that already supply major Australian and international customers, and close proximity to Asian markets. It produces a wide range of hydrocarbon products, ranging from more than 7.5 million tonnes of liquefied natural gas a year, to more than 50 million barrels of oil and condensate and 650,000 tonnes of liquefied petroleum gas a year and 4.5 bcm (500 million standard cubic feet) of piped natural gas for local markets per day. The development of this wide range of products began with establishment of the venture's first offshore gas and condensate production platform, then the biggest in the world, in the mid - 1980s
Far East: A once hot area begins to cool
1986-08-01
This article presents the petroleum outlook for the Far East area. The primary observations are: Chinese drilling and production rise again, but offshore is a BIG disappointment; Exploration will decline in Indonesia, but development will take up some of the slack; Liberalized contract terms should bring international operators back to Malaysia; Having found sufficient gas reserves, Union will cut activity in the Gulf of Thailand; Things are slow in Brunei, but the country has plenty of cash to weather the storm; An important offshore wildcat came up dry, but Pakistan's exploration is paying off; India's ambitious plans are getting trimmed back and a call goes out for outside help; Two new operators sign exploration contracts in an otherwise dead Philippines.
Experimental LabourOffshoring Clinical Trials to China
2008-01-01
The State Food and Drug Administration of China has reported a dramatic increase in multicentre, multinational clinical trials over the past several years. This is in keeping with a growing trend towards the off-shore outsourcing of clinical trials from North America and Western Europe to nontraditional locations such as Eastern Europe, China, and India. Within China, the post-socialist reform of health care, internal divisions of labour and the politicization of the healthcare system have all created the conditions under which contract clinical trial work is becoming an imperative both for hospitals and the growing number of working uninsured. The paper brings together a critical insight into current theories of bioeconomic innovation with new political economies of informal labour ...
Abu Dhabi boosting oil production capacity
1991-12-02
This paper reports that Abu Dhabi is increasing its oil production capacity in step with several other key producers in the Middle East. With international oil company partners, Adnoc works onshore as part of Abu Dhabi Co. for Onshore Operations (ADCO) and offshore as part of Abu Dhabi Marine Operating Co. (ADMA-OPCO). In addition, Adnoc holds sole-risk concessions offshore and onshore (see map). ADCO is developing condensate reserves in the Thamama F formation at Bab field. It will inject gas from the Thamama C formation to maintain reservoir pressure in a project expected to recover more than 80 million bbl of condensate.
