In recent years there has been an increase in wind power plants installed out at sea. The generated power of wind turbine generators (WTGs) are collected through numerous subsea cables into a single hub, the offshore platform. Subsequently, this platform is interconnected with the onshore main grid through a further stretch of cable. In the event of a fault, a sudden increase in current, so called short-circuit current, will occur somewhere in the system. The short-circuit current will, dependin...

<p>The depositional environment of the <i>Bigenerina humblei</i> 1, <i>Bigenerina humblei</i> 6, and <i>Amphistegina</i> &ldquo;B&rdquo; 1 sands of the Hog Bayou field in Cameron Parish, Louisiana, was investigated. To complete the investigation, analysis of well log data, along with the preparation of structure, isopach, and fault plane maps, as well as cross sections, were completed for the four sands. Paleontological data and regional literature pertaining to deposition were also utilized. </...

Amongst the available renewable energy sources, offshore wind energy is having a rapid expansion. Renewable energies are viewed as an environmental benign alternative to the energy production based on fossil fuels, but the emerging development of offshore wind energy has also raised public concern over its potential impact on seabird communities. To assess this impact, seabird distribution and abundance maps are usually included in Strategic Environmental Assessments (SEA) and Environmental Impa...

In the Southeastern Iberian Margin, the compression between the African and Eurasian Plates is characterized by a moderate seismicity and a slow NW-SE convergence (4.5-5.6 mm/yr). In southeastern Spain, this shortening is mainly absorbed by a left-lateral strike-slip fault system known as the Eastern Betics Shear Zone (EBSZ) characterized by a long recurrence activity. Preparedness in the face of future earthquakes entails the detection and the characterization of all the possible seismogenic so...

Integrating multi-channel reflection seismic data with well data, we observe three regional sequence boundaries: Middle Miocene unconformity, Pliocene downlap surface, and Pliocene-Pleistocene unconformity, indicating the formation of foreland basin, the fulfillment of foreland basin, and the erosion of foreland basin and orogeny, respectively. We find the outer C...

La simulation numérique des éoliennes flottantes est essentielle pour le développement des Energies Marines Renouvelables. Les outils de simulation classiquement utilisés supposent un écoulement stationnaire sur les rotors. Ces théories sont généralement assez précises pour calculer les forces aérodynamiques et dimensionner les éoliennes fixes (à terre ou en mer) mais les mouvements de la plateforme d’une éolienne flottante peuvent induire des effets instationnaires conséquents. Ceux-ci peuvent ...

ABSTRACT This study applies seismic attributes to the high-resolution 3D reflection seismic data acquired for the deepwater exploration block in the Orange Basin, offshore South Africa, to provide insight into the mechanisms controlling deformation in hydrocarbon systems. The seismic interpretation was carried out on high-resolution, prestack time-migrated 3D seismic data that image post-rift sequences from the Upper Cretaceous to the Quaternary. Three post-rift sequences were identified in the...

<p>Abstract A geophysical analysis was carried out to delineate and characterize the Mid-Miocene Moki sandstone reservoir in the Taranaki basin, offshore New Zealand. The study is an effort to use the new 3D seismic from the Parahaki survey to answer some concerns of an earlier 2D seismic line that drilled a dry hole. Well log curves were used to identify two sands within the Moki package (Moki-1 and Moki-2). Amplitude Variation with Offset (AVO) forward modeling was done to evaluate the seismic...

<p> Offshoring software projects have been common for a few decades and were once thought to be the savior of software development project issues that plagued in-house software developers. Even with many recent advances in software development and communication, many projects are still compromised in some way. This dissertation analyzes in-house and offshore projects that were conducted using the waterfall methodology to determine the real source of the issues. The main hypothesis here is that b...

After a period of high activity within the offshore sector in Norway, they now experience a decrease in activity. At the same time, the railway sector is experiencing high activity and new investments. This leads to a shift in the need of engineering expertise.

Large-scale stratal architecture, structure, and commonly hydrocarbon distribution in the Mississauga Formation, Sable Subbasin, offshore Nova Scotia, can be satisfactorily explained by shelf margin progradation. Using an integrated subsurface dataset (2-D and 3-D seismic data, biostratigraphy, geophysical well logs, core), the physical characteristics and depositional history of the Missisauga Formation (Tithonian-Barremian) were studied on both local and regional scales. These data suggest tha...

This thesis is concerned with one aspect of government management regimes for offshore oil and gas - the allocation of rights over these resources. The method by which rights may be acquired, the scope of the rights, and the terms and conditions upon which they are obtained are matters of great significance in determining the overall effectiveness of a management regime. Four coastal nations have been chosen for study. They are the United States of America, the United Kingdom of Great Britain a...

This study is aimed at developing a workflow for quantitative seismic interpretation. The workflow generated probability maps of various facies and pore-fluid by combining seismic attributes and wireline log data through rock physics relationships and supervised statistical classification. The workflow was developed mainly for hydrocarbon exploration, but could be used for other purposes, provided the target is seismically detectible. Any prior regional geological knowledge is built into the wor...

The three phase permanent magnet synchronous generator with full scale converter arrangement has gained significant market share in win energy turbine topology. This is because of the advancement in production of superior magnetic properties and steady decline in price of the magnets. Permanent magnet synchronous generators are of compact in size and light in weight. They become attractive for offshore wind application. But offshore wind energy system has to be not only light weight and compact...

An explosion on a typical offshore installation is a critical, however rare accidental event which may result in damage and loss of property, and in the worse case loss of lives. Top-side sections on an offshore installation which are exposed to an explosion blast should be designed to withstand such an event in a way that further escalation of the damage on personnel or property is avoided. There is however limited information on the modeling and analysis procedures for dealing with such events...

New Zealand initiatives to address supply-chain labour conditions are tending towards reliance on Corporate Social Responsibility (CSR), a form of private regulation. This thesis explores the effectiveness of private regulation for improving labour conditions, and reasons for its emergence, using the case study of the New Zealand-China relationship. It is argued that CSR brings only cosmetic improvements to a minority of workers in China. It is no replacement for strengthened law enforcement and...

The stratigraphic organization of clastic successions deposited during the early synrift phase is controlled by the rates of tectonic subsidence and the growth of the master faults, which, coupled with eustatic sea-level changes, control the generation of accommodation. The highly heterolithic, Lower Jurassic Upper Åre and Tilje succession (100 to 300 m thick), which occurs in the Halten Terrace of offshore Norway, represents an excellent example of ancient synrift deposits that accumulated with...
