This research explores the different envisioned roles of gas infrastructure for integrating offshore wind into the energy system of the North Sea Region (NSR). In this research, the NSR is defined as consisting of the Netherlands, Germany, Belgium, Norway, Denmark and the United Kingdom. The NSR is characterized by the increasing use of their...

The increasing capacity of offshore wind energy around the world brings challenges in Operation and Maintenance (O&M) management. Over the past years, many studies have focused on developing sound maintenance strategies in order to minimize maintenance cost or maximize availability. One of the promising maintenance strategies is...

Floating offshore wind turbines can only withstand a limited amount of (heave) motions before the equipment fails. In order to reduce the heave motion, the DeepCwind floater for offshore floating wind turbines makes use of heave plates. This semi-submersible floater consists of three cylindrical columns with a heave plate attached to the bottom...

This thesis focuses on modelling a gravitational launch of gravity based foundations (GBF's) for offshore wind turbines. This is an extension of the Blyth Offshore Demonstrator project by BAM Infraconsult. To become more competitive in the offshore wind energy market, the construction of self-buoyant GBF's installed using the `float and submerge...

To meet the goals of the Paris Agreement, the Netherlands is integrating large amounts of offshore wind energy into the power system and has ambitious plans for the coming years. A grid topology with transmission capacity above 1 GW connecting offshore wind farms (OWFs) at distances close to 100 km in a standardized, modular, and cost...

Wind farms are currently built in the North Sea in the Netherlands. The grid connecting the off-shore wind farm to the main-land distribution grid must be protected against short-circuits and other electrical disturbances. In this project is studied if electrical protection of a grid is suitable for grids connecting renewable energy sources to...

Cirillo, Raffaello (author)
Nowadays an increasing number of offshore wind farms (OWF) is getting built. Several disciplines are considered into this subject. The manual and sequential design approach used so far is not sufficient to guarantee optimized systems because interactions between the different components are disregarded. Therefore, engineering companies are...

Bailleul, Wouter (author)
Surrogate models are used to approximate the expensive ‘true’ simulation codes and thus have the potential to speed up the wind farm layout optimisation problem (WFLOP). One technique to make surrogate models is Polynomial Chaos Expansion (PCE). PCE can approximate a (wind farm) model by using orthogonal polynomials which are constructed based...

Offshore Wind Farm (OWF) installation procedure is a complicated phase requiring excellent management of resources for timely completion of tasks. The wind farm installation period involves crucial stages like streamlining onshore logistics, transportation of components on vessels, installation of foundations, wind turbines, and cable laying,...

The European energy system is significantly changing to restrict the rise in global average warming. There is a shift from fossil fuels to renewable energy sources, which resulted in an exponential growth of offshore wind energy capacity in the North Sea. However, the North Sea is already one of the most intensively used sea basins in the world...

In order to meet future energy demand, a more sustainable energy society is essential because fossil fuel reserves are depleting while the total energy consumption worldwide increases. One type of renewable energy which can play a role is ocean energy having the theoretical potential to exceed both current and future human energy needs. This...

Due to the increasing need for energy from renewable resources, a large number of offshore wind farms are planned to be constructed in the near future. Despite the plethora of available foundation concepts for offshore wind turbines, the monopile foundation is the most widely adopted concept in practice. To predict the installation process for a...

As part of the effort to reduce the cost of offshore wind energy, this MSc Thesis deals with the layout optimization of an Offshore Wind Farm affected by wake effects, cable topology and support structure variation. The main objective of the current MSc Thesis is to investigate how important each of these aspects for the layout optimization is....

The wind energy industry in order to find stronger winds, has to go further offshore and move into deeper waters where bottom founded wind turbines cannot be deployed anymore. This is the main reason why floating wind turbines have been studied extensively in the past years. In the case of regions with cold climates, ice loads become significant...

There is an increasing interest in using offshore wind turbines in deeper waters. The tension leg platform wind turbine (TLPWT) is seen as a promising concept for this. Low production costs and limited motions give the TLPWT concept both economic and dynamic advantages. Previous studies regarding dynamic analysis of offshore floating wind...

Leimeister, M. (author)
Floating offshore wind turbines are taking on more and more prominence, as the industry moves towards larger turbines, farther offshore, in deeper water. The increase in turbine size can reduce the costs of offshore wind energy, but requires larger support structures. Rather than redesigning the structure completely, a rational methodology for...

Further advancements in the offshore wind industry, which come with the use of larger wind turbines at deeper water, require larger support structures. For shallow and intermediate water depths, monopile foundations still remain the most widely-used and cost-effective support structure due to the relative simplicity of fabrication and...

Offshore wind energy faces three important trends: (1) wind farms grow in size, (2) monopiles are installed in deeper water, and (3) cost reduction remains the most important challenge. With wind farm size, the importance of variations in environmental site conditions across the wind farm increases. These site variations, e.g. water depth and...

When large amounts of electricity need to be transported for long distances, or when underground or submarine cables are involved, using direct current high-voltage transmission systems is more efficient and cost effective than using traditional high-voltage alternating current transmission. Therefore, the main thesis objective is to study to...

For achieving the European renewable electricity targets, a significant contribution is foreseen to come from offshore wind energy. Considering the large scale of the future planned offshore wind farms and the increasing distances to shore, grid integration through a transnational DC network is desirable for several reasons.
