Lammers, Anneli (author)Van Oord is active in the subsea cable installation industry and executes most of their cable lay projects with their cable laying vessel: The Nexus. In this thesis the focus lies on the normal lay phase of the cable installation, which comprises the phase when the vessel is pulling out the cable and putting it down on the seabed following the...master thesis 2020

van der Drift, Maarten (author)One of the world’s biggest concerns is global warming, a solution to this can be wind energy. Offshore wind energy has advantages over onshore wind energy, however, the levelized cost of energy is higher. The maintenance costs are a major cost contributor. To lower these costs, research is performed on faults and its detection. Currently, little...master thesis 2020

van Beek, Maarten (author)Wind farms experience significant efficiency losses due to the aerodynamic interaction between turbines. A possible control technique to reduce these losses to a minimum is yaw-based wake steering. This thesis investigates the feasibility of this technique by calibrating a surrogate model called the FLOw Redirection and Induction in Steady-state...master thesis 2020

Bussemakers, Matthijs (author)Climate change, as a result from global warming, requires an energy transition: the reduction of greenhouse gas emissions from fossil fuels and a radical innovation of the global energy system to proceed apace. Offshore wind is an important source of clean, renewable energy, and it plays a key role in the transition. 80% of the worldwide...master thesis 2020

Boogaart, Lukas (author)The yearly installed percentage of offshore wind jacket substructures is rising. The most common installation method for a jacket structure nowadays starts by driving the foundation piles in the seabed through a pre-piling template. The jacket is then lowered on top until the legs are resting on the foundation piles through friction-based...master thesis 2020

Yagüe Martín, Adrian (author)Premature failures in large offshore Wind Turbines are often attributed to bearing failure despite gearboxes being designed and developed using the best bearing design practices. Furthermore, as turbine size and rated power increase, bearings display an enhanced tendency to fail. Unscheduled bearing replacement at sea is a complex, costly,...master thesis 2020

Desmedt, Michiel (author)Wind energy has shown to be a great renewable energy source, with a possible penetration of 20 % by 2040. In order to increase its competitiveness with fossil fuels, the LCOE should decrease further than it already has. Increasing the power rating of wind turbines has proven to be an effective way to achieve this. However, this results in...master thesis 2019

Sethi, Shubham (author)The increasing penetration of PE converter interfaced generation units in electrical power systems have given rise to many challenges in the power system operation. Two of the most important challenges are the voltage control and frequency control in the absence of conventional generation units. Furthermore, the PE converters can interact with...master thesis 2019

Duffy, Patrick (author)The engineering flow models used to estimate annual energy production (AEP) in offshore wind farm layout optimization typically assume inflow homogeneity over the model domain. This assumption lies in contrast with observations of horizontal wind speed gradients in coastal regions where many offshore wind farms are being constructed. Accounting...master thesis 2019

van Hoogstraten, Sara (author)Offshore wind energy is considered a necessary renewable energy resource, that may stimulate the transition from fossil fuels. Following the successful development in Western Europe, offshore wind is quickly gaining momentum in the Asia-Pacific region. At variance with North Sea-based offshore wind turbines, structures installed in the Asia...master thesis 2019

Lee, Jaehyeun (author)Fatigue is often a governing design factor for offshore wind turbines. Since the design of offshore wind turbines includes conservatism, the actual accumulated fatigue damage can be lower than what the turbine is designed for. In this case, the operator can make a decision on life time extension of existing wind turbines. Therefore, it is...master thesis 2019

Blok, Sanne (author)Offshore wind turbines are commonly supported by monopile foundations. Impact hammering is the conventional method for installing offshore monopiles but has several disadvantages. Time-consuming installation procedures, high noise emissions and steel fatigue due to the high impact are problems resulting from this installation procedure. GBM...master thesis 2019

Muller, Jelle (author)The offshore wind industry has grown rapidly over the last decade and drivetrains are increasing in size to reduce the cost of energy. These turbines are operating in a harsh environment. Adopting a preventive maintenance strategy is important to achieve an as high as possible availability of the farm and reduce the cost of maintenance. A well...master thesis 2019

de Korte, Bart (author)Within this thesis influence of thrust vectoring for VAWTs, controlling the magnitude and direction of the thrust vector with respect to the freestream, is investigated through active pitch actuation. The H-type Darrieus VAWT is modelled in 2D through the actuator cylinder model with the Mod-Lin correction included. The evaluations are performed...master thesis 2019

Bouman, Thijs (author)The growing interest in the development of offshore wind farms in seismic active areas demands a better insight into the requirements earthquakes impose on the design of wind turbine foundations. The complexity of the soil-structure interaction (SSI) during an earthquake results in large uncertainties in the design process of a monopile...master thesis 2018

Baharvand, Amir (author)Delamination is one of the common failure types in the fiber composites. The trailing edge in the wind turbine blades, for example, is one of the structural components where the delamination is driven by mode III under predominantly flapwise loading. There has been an extensive effort in developing test procedures and test specimens for...master thesis 2018

Partha Sarathy, Pankaj Raghav (author)In recent years, distribution networks have been facing voltage quality issues due to the influx of renewable energy. Rural areas which are ideal for renewable energy development due to large vacant areas are faced with grid voltage variations due to long distribution lines. Because of the stringent conditions laid by the Distribution System...master thesis 2018

Seijas Fernandez, Andres (author)EU carbon emission targets related to climate change has set in motion a process of transition towards an environmentally clean and sustainable power system. A central focus on this process is the transition from fossil fuel based energy sources to clean Renewable Energy Sources (RES). However, the intermittency of RES (e.g. solar and wind)...master thesis 2018

Bossuyt, Ottelien (author)The wind field and, more importantly, the power production change when downstream wind turbines are located in the wake of an upstream wind turbine. Wind farms become larger and therefore the field becomes more complex. Turbines will experience the influence of the wake of multiple wind turbines. The interaction of these wakes can be modelled...master thesis 2018
