The continuously developing requirements of the offshore oil and gas Operators are placing more stringent demands on the designers to produce optimised solutions, with reduced development schedules, and application of new technologies for extreme environmental and operational conditions. The compounding uncertainty of service conditions and in the design capabilities is causing the designer to over-design, conduct extensive pre-service testing and introduce design redundancy. As such, designers ...

The Provinces of British Columbia, Nova Scotia, Prince Edward Island, New Brunswick and Newfoundland are all seeking control over offshore resources, that is the natural resources within the waters beyond their coastlines. Provincial demands have ranged from challenges of the federal government's claim to ownership of these resources to discussions of schemes whereby management of the offshore resources would be shared by the provincial and federal governments. There has not been any conclusive ...

Ice features present one of the major obstacles to offshore development in the Arctic and Atlantic regions of Canada. Ice features have been observed to interact with the see floor creating scour features (Clark et al., 1986). In particular, when an ice feature is driven by environmental forces into the shallow water, ice scouring of the seabed may cause a danger to bottom installations such as submarine pipelines. In the present study, the ice-scour event in a centrifuge test is simulated by us...

Notwithstanding that civil liability for pollution damage as well as compensation is emphatically recognised and established under international treaty, there is a conspicuous absence of a single comprehensive regional framework as well as universal treaty that address this issue with regards to offshore oil and gas exploration. The reason for this might not be unconnected to the occasional occurrence of offshore platform and oil well blowouts. Meanwhile, offshore operations pose a constant...

Mon travail porte sur la construction de générateurs aléatoires de conditions de vent en Bretagne. Ces modèles permettent de simuler artificiellement des conditions météorologiques réalistes et sont couramment utilisés pour la gestion des risques liés aux aléas climatiques. Ils sont construits sur la base de données historiques dans le but de produire des simulations cohérentes avec le climat actuel mais peuvent intégrer des scénarios de changement climatique. Les séquences simulées permettent d...

Sediment contamination poses a significant problem within aquatic systems. Metals as a pollutant are a major concern because of their toxicity, persistence and non-degradable nature. This study measured sediment metal concentrations within Louisianas coastal estuaries and offshore shoaling regions over a three year period. This was done to determine current concentrations, examine the relationships of physico-chemical, spatial and temporal variables with the metals and compare the metal concentr...

4D seismic analysis is used to understand the performance of a producing oil field in order to increase production and mitigate risk. This is done by interpreting changes in water saturation and changes in effective pressure in the reservoir, which allows production to be maximized safely. In this project, I determined saturation and pressure changes in an oil field offshore Equatorial Guinea. I used Landrø's technique as a basis for the analysis, however Landrø's technique requires the presence...

The nutrient dynamics in two contrasting estuaries and in the adjacent nearshore environment along the south-east coast of South Africa was investigated seasonally. Due to an inter-basin transfer of water from the Gariep Dam to the Great Fish River, the Great Fish estuary is a fresh water dominated, terrestrially driven system with an annual fresh water inflow of 250 – 650 x 10⁶ m³ per year. In contrast, the Kariega estuary is a fresh water deprived, marine dominated system with a fresh water in...

This is a three year (1992-1995) longitudinal study of the Guaymas, Sonora, offshore shrimping industry in the Gulf of California. In early 1990's two events coalesced to practically paralyze the Mexican offshore shrimp industry. First, shrimp production dropped precipitously, 68% in one season, bankrupting cooperatives and almost all but the wealthiest private boat owners. Secondly, a formerly populist government adopted "structural adjustment" policies as requirements for debt restructuring, a...

This thesis deals with the plan of the Dutch government to build an offshore airport outside its territorial waters. Because the airport will be outside territorial waters several problems may arise. Under the Law of the Sea the question is whether such an airport can lawfully be built and what the different conditions are under which it is possible. The Convention on International Civil Aviation is older then the new Law of the Sea Convention and therefore not up to date with the new zones in t...

The events surrounding the Deepwater Horizon disaster have changed the face of deepwater operations. In order to continue drilling in the Gulf of Mexico, the regulatory body, the Bureau of Safety and Environmental Enforcement (BSEE), has required that applications to conduct work in the Gulf of Mexico (GOM) include a plan to stop, capture, or contain any uncontrolled release of fluids. The capping and containment systems built and implemented by BP during the event are an excellent starting poin...

The size of offshore wind generators is increasing, and the trend is moving towards full converter gear-less solutions with permanent magnet synchronous generators (PMSG). The nacelle weight reduction is a key design criterion for offshore wind turbines. To overcome the weight challenge, a transformer-less concept is under development. This concept employs a special PMSG with an innovative high insulation level between the groups of windings. The generator supplies nine series connected converte...
