Power optimization through wake steering and axial induction control is a well investigated topic in wind energy, which is generally proven to work. The influence of control manoeuvres on the fatigue of static components is generally discussed, but drivetrain fatigue due to wake steering and axial induction control is rarely discussed, while it...

The quest for affordable renewable energy causes the need for bigger and more efficient wind turbines. To counter the problem of possible collisions between the growing turbine blades and the tower support structure, downwind turbines might be a solution. For this configuration, blade flexibility no longer forms a problem and besides that...

Offshore wind turbines (OWTs), together with their support structures, are designed for an operational period of 20 years. The first generation of these offshore wind turbines has already reached or is approaching their designed lifetime of 20 years. Depending on the legislation and the governmental subsidies, a decision needs to be made about...

This thesis project has set out to investigate the response in fore-aft direction of a monopile wind foundation supporting an NREL 5MW turbine, offshore the coast of Taiwan, which is affected by weak to strong earthquake ground motion in combination with normal sea state conditions. The soil at the location of the monopile is layered, with sand...

Vortex Induced Vibrations (VIV) is a well-known and explored topic. It is a quite complex phenomenon as it is part of different disciplines including fluid mechanics, structural mechanincs, vibrations and computational dynamics. It can be found in many engineering applications such as bridges, industrial chimneys, transmission lines, marine...

The wind energy industry is booming. In 2017 the installed wind capacity has overtaken coal as the second largest form of power generation in Europe. Costs of wind farms are driven down, and even the first offshore wind-farm contract without subsidies is a fact. Installing the Wind Turbine Generators (WTGs) more efficiently increases the profit...

One way to implement a wind turbine in the sea is to use lattice structures. Since these structures are placed offshore, they must be able to withstand all kinds of loads. It is essential that the eigenfrequencies of the support structure do not correspond to the passing frequencies of the blades and any other dynamic actions. To avoid this the...

In the transition from a fossil fuel driven economy to renewable solutions, the activities in offshore wind energy are growing. Operation and maintenance costs of offshore wind turbines are high, therefore alternative methods should be developed to reduce these costs. The replacement of heavy components, like a gearbox or a generator, is a...

In order for the offshore wind industry to be competitive, the cost has to be driven down. One of the major factors that contribute to the overall cost is the over-dimensioning of the substructure. The response of the structure under various loading conditions can provide valuable insight in the design phase so as to provide a structural design...

In the Dutch coastal waters more and more wind turbines on monopile foundations are built. An important design parameter is the first natural frequency of the wind turbine. The first natural frequency is dependent on environmental conditions and different soil conditions such as scour. This research gives a better insight into the sensitivities...

The monopile is the prevailing foundation concept applied in offshore wind farms, mainly due to construction of offshore wind farms in relatively shallow water. The monopile can provide a technically and financially feasible solution in shallow water environment due to its’ ability to support the wind generator ensuring at the same time the...

Currently, the foundation design of offshore wind turbines is based on a simple cantilever beam model with a mass representing the rotor and nacelle, or by making use of wind turbine simulation software such as Bladed, which are built for rotor design. The simple models are unrealistic since the dynamic interaction between the aerodynamic loads,...

Renewable energy generated by offshore wind turbines (OWT) are nowadays more frequently used in the offshore industry. The design of OWT foundations share similarities with a typical offshore oil and gas construction, however a OWT farm usually consist of multiple foundations whose installation are more cost-sensitive compared to one oil and gas...
