Bouwmeester, Boudewijn (author)The increasing global demand of renewable and clean energy has led to the exponential growth, development, and interest in the offshore wind energy industry and expansion towards earthquake-prone areas. Offshore wind turbine structures, typically supported by a tubular monopile foundation, are increasing in size to meet the increasing human...master thesis 2022

Saccone, Cecilia (author)The idea of shared mooring systems has been introduced in the offshore wind farm industry as an effort to lower the overall installation costs for floating offshore wind farms. The reason for building such plants is that using floating turbines allows them to move to deeper waters, reducing visual and environmental impact and allowing footprint...master thesis 2022

van der Spek, Joep (author)Reducing the levelised cost of energy is crucial to accelerating the energy transition. To develop offshore wind solutions in greater water depths, a floating solution is required. The time-domain simulations of these Floating Offshore Wind Turbines (FOWTs) under wind-wave misalignment used in research and industry projects are computationally...master thesis 2022

Luesutthiviboon, S. (author)Nowadays, large wind turbines are installed and operated close to densely populated areas due to the growing need for renewable energy. Noise constraints are hampering this development. The most relevant wind turbine noise source is the so-called Turbulent Boundary Layer Trailing-Edge (TBL–TE) noise. Many passive TBL–TE noise reduction...doctoral thesis 2022

Delavinia, Dimitra (author)New offshore wind farms consisting of monopile-founded Offshore Wind Turbines (OWTs) are to be built in earthquake-prone areas. To design the monopile foundation and to accurately define the dynamic response of an OWT, the soil-monopile-superstructure interaction should be modelled properly. Due to the fact that the Three-Dimensional (3D) Finite...master thesis 2022

Kumar, Arnav (author)The demand for electric vehicles (EVs) and wind turbines have been rising significantly in the EU as the EU wants to become carbon neutral by 2050 and generate 40% of its energy through renewable sources in order to avoid climate change and its consequences. However, both these technologies use several critical raw materials essential for their...master thesis 2022

Savana, Reshab (author)The growing demand for renewable energy has led to significant developments in wind turbine technology. The ever increasing size of turbine blades and their exposure to a variety of environmental factors can affect their annual energy production and service life. Erosion caused by rainfall and hailstones is identified as two of the most...master thesis 2022

REPPAS, APOSTOLOS (author)Renewable forms of energy, and especially wind energy, have become an integral part of the energy infrastructure around the globe. However, the constant increase of installed wind capacity has put a strain on the selection of potential onshore locations for wind turbine installation. As a result, the wind industry is focusing on offshore...master thesis 2022

Sanders, Servaas (author)Wind energy has seen a transition from onshore to offshore in the last decades. The lack of space on land and up-scaling of turbine sizes led to the need of exploiting further away and harsher environments, where more space is available and there is arguably less of an impact on society. This together with a higher supply of wind resources has...master thesis 2022

Blom, Ruben (author)The increased awareness of the negative consequences of man-made climate change has given rise to a fast growing offshore wind industry. Wind turbines become increasingly larger, and available locations for offshore wind farms are shifting towards deeper waters, where jack-up vessels can no longer be used for installation. Heerema Marine...master thesis 2022

de Jong, Olivier (author)In contrast to traditional power cables for bottom-founded offshore wind turbines, power cables for floating wind turbines penetrate the water column and are exposed to cyclic loading. Due to the dynamic nature of the cable loading, the cables are prone to fatigue failure. Since the evaluation of the fatigue life of complex structures, like...master thesis 2022

van de Krol, Bart (author)The most used RANS-model in relation to wind farms, k−epsilon, has significant shortcomings. It over-predicts the eddy viscosity in the near-wake and fails to model the anisotropy of the turbulence quantities. The Sparse Regression of the Turbulence Stress Anisotropy (SpaRTA) method could remedy these shortcomings. This method uses temporally...master thesis 2022

van Wilgen, Bert-Jan (author)This research examines the difference between two major component replacement strategies for the novel floating offshore wind turbines (FOWT), in terms of support vessel CO2eq emission and cost together with FOWT downtime. The first strategy is utilising a crane vessel to replace a component in offshore, this is called the heavy lift maintenance...master thesis 2022

Mordasov, Dmitrij (author)With the growing global utilisation of wind energy, lowering of its levelised cost of energy is pursued. This effort is hindered by wind turbine wakes and their detrimental effects on wind farm profitability. Most currently researched wake mitigation methods are based on wind farm system-level interventions, and there is a research gap on...master thesis 2022

van Nie, Daan (author)In the low-lying parts of The Netherlands challenging ground conditions are often encountered. Thick layers of soft material such as peat and clay are present and pile foundations into deeper sand layers are required when objects are constructed that have to transfer significant loads to the subsurface without inducing settlement (differences)....master thesis 2022

Eijkhout, Thijs (author)Wind turbines have proven to be an essential part for the green energy mix. However, the focus was mainly on the horizontal axis wind turbines whereas the vertical axis wind turbine did not receive that amount of attention. In this work a straight-bladed vertical axis wind turbine (SB-VAWT) is explored which can temporary adjusts its rotor...master thesis 2022

VOULTSOS, IOANNIS (author)The energy transition towards carbon neutrality requires a rapid electrification of all energy sectors by 2050. In the EU-27, the REPowerEU strategy, initiated in March 2022, is pursuing this target even more ambitiously. However, in order to achieve the aforementioned goals, the increasing demand for green hydrogen will...master thesis 2022

Seegers, Jeroen (author)The slip joint connection is a relatively new alternative method for connecting offshore wind turbine towers to prior installed monopiles. It consists of two overlapping conical sections that together form a connection. There are several challenges left to be solved before the slip joint can be applied on a commercial scale. One of those...master thesis 2022

Burggraaf, Diego (author)New trends in the offshore wind industry show that wind farms are being built further onto sea. This also means that turbines have to be installed in deeper waters resulting in new challenges for the offshore wind industry. The commonly used jack-up vessels have a limited operating depth and therefore floating installation vessels become an...master thesis 2022
