Until recently, there has been very limited academic palynological study of South Africa’s offshore west coast Cretaceous sequences. For this thesis, an in-depth study of the palynological sequence as well as a combination of other disciplines was undertaken for Offshore Sites C-B1 and O-A1, situated off the west coast of Cape Town. The study has yielded copius amounts of mostly well-preserved palynomorphs (trilete spores, pollen, diniflagellate cysts and foraminiferal test linings) ranging...

Offshore floating wind turbine technology is growing rapidly and has the potential to become one of the main sources of affordable renewable energy. However, this technology is still immature owing in part to complications from the integrated design of wind turbines and floating platforms, aero-hydro-servo-elastic responses, grid integrations, and offshore wind resource assessments. This research focuses on developing methodologies to investigate the technical and economic feasibility of a wide ...

Background: Organizations want to reach shorter development cycles to stay competitive, meanwhile, many organization wants to globalize their business to obtain benefits like reduced cost, get hold of specific talent or gain global presence.  Typically in software development projects, there is a gap between development and operation resulting in a longer development cycle due to inferior communication and collaboration. DevOps is a framework that intends to reduce this gap with the purpose to r...

The installed capacity of offshore wind turbines in Europe is increasing with the monopile being the most common type of foundation. During its lifetime an offshore wind turbine is exposed to high dynamic loads which eventually can result in the fatigue of the substructure. This thesis will show how the linear damage accumulation approach based on the Miner’s rule can be used to estimate the damage induced on the substructure of an offshore wind turbine using measurements from strain gauges. Fur...

The United States manufacturing employment decreased 33% from 1985 to 2014. During the same period, the United States semiconductor manufacturing, accounting for 1.7% of the total of the United States manufacturing workforce, lost 35% of its employees. The decline in semiconductor manufacturing jobs began in 1985 when semiconductor firms began offshoring product manufacturing overseas because of low cost of qualified labor force and facilities. This qualitative case study explored the analytical...

Increasing reliance on renewable energy promises to reduce carbon emissions. Although national-scale polls demonstrate high levels of public support for developing renewable energy, local opposition has led to cancelations of renewable energy projects globally. This dissertation empirically investigates barriers to the siting of offshore wind farms in reference to their perceived risks and benefits; people’s willingness to pay to mitigate environmental risks; values that influence these choices ...

Homer, Jeffrey R.

As offshore wind technology advances, floating wind turbines are becoming larger and moving further offshore, where wind is stronger and more consistent. Despite the increased potential for energy capture, wind turbines in these environments are susceptible to large platform motions, which in turn can lead to fatigue loading and shortened life, as well as harmful power fluctuations. To minimize these ill effects, it is possible to use advanced, multi-objective control schemes to minimize harmful...

The evaluation of design iceberg impact loads for offshore structures and the influence of hydrodynamic effects on impact loads are examined. Important hydrodynamic effects include iceberg added mass, wave-induced oscillatory iceberg motions, and the influence of a large structure on the surrounding flow field and subsequent velocities of approaching icebergs. The significance of these phenomena has been investigated using a two-body numerical diffraction model and through a series of experimen...

The objective of the work described in this thesis is to evaluate the significance of the ambient fluid on the motion of an ice mass in the vicinity of an offshore structure and during the subsequent impact mechanism. Models for iceberg drift are first reviewed. The changes in flow field around an ice mass drifting in a current near an offshore structure are investigated by potential flow theory. The proximity effects and current interactions are generalized by introducing the added mass and co...

A numerical method is described to study directional wave effects on large offshore structures of arbitrary shape, based on an extension of linear diffraction wave theory for regular waves. A computer program has been developed to compute loading transfer functions and response amplitude operators and hence the loading and response spectra for both long- and short-crested random waves. Cosine powered directional spreading functions which are independent of frequency have been used to account for...

Recent events regarding energy policies throughout the globe and advances in technology are making offshore wind farms become a reality. Most offshore wind farms are still, however, built close to land masses, and need to be rigidly attached to the seabed in one way or another.
