Douma, Laurens Jan (author)The replacement of conventional generation units with variable renewable energy sources could have a negative impact on the balance of supply and demand of electricity. Moreover, since the variable renewable energy sources are inverter based and therefore decoupled from the grid, the overall grid inertia will decrease. To solve this problem, the...master thesis 2023

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

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

Huigen, Vincent (author)The offshore wind industry is a quickly growing market because the increasing demand for clean energy sources. Large wind speeds and the abundance of potential wind farm locations make Offshore Wind Turbines an interesting solution. Because of high continuous dynamic loading and extreme environmental conditions, the structural design requires a...master thesis 2021

Laanes, Mikk (author)Technology improvements and growing maturity of the offshore wind industry have resulted in significant cost reductions and rise in demand. More can be achieved by focusing on improving the understanding of key design areas of an offshore wind turbine (OWT). Since fatigue is one of the main design criteria for offshore structures and little is...master thesis 2021

Hogerheijde, Joost (author)To reach the Paris Agreement goals, switching from fossil fuels to renewable energy is inevitable. Wind power has proved to play a critical role in this transition. To speed up this transition, the wind industry must keep innovating. The major part of Wind Turbine Generators (WTGs) is installed by a jack-up which not only has its limitations...master thesis 2020

van de Ven, Bas (author)With increasing demand for renewable energy, the offshore wind industry is ever growing. Wind turbine generators (WTGs) proceed to grow in numbers and in size, wind farms are located further offshore, in deeper waters, poorer soil conditions or in areas prone to earthquakes. These changes make it increasingly difficult to find capable and...master thesis 2019

Janse, Arnout (author)The offshore wind industry is entering a new level of maturity. Announcements of bigger offshore wind turbines, the interest in new locations for offshore wind farms in harsher environments and the appearance of zero subsidy bids are proof of a rapid development. The next generation turbines are expected to be significantly larger and heavier...master thesis 2018

Foursoff, Willemijn (author)The API RP 2GEO (2011) p-y method is an industry standard approach to predict the lateral pile behaviour of slender oil platform piles with length (L) over diameter (D) ratios > 10. However, offshore wind turbines are founded on large diameter monopiles with an L/D ratio < 8, which are rather rigid piles. There are concerns about the...master thesis 2018

van Beek, Merel (author)Since the oil price collapse at the end of 2014, operators in the offshore industry experience a decline in revenues and a need for downsizing. Simultaneously, the wind industry is growing every year, as an increasing amount of companies and consumers are investing in green energy. This creates opportunities for Heerema Marine Contractors (HMC),...master thesis 2018

Daamen, Joris (author)Trends towards higher capacity offshore wind turbines (OWTs) and deeper offshore wind farm sites, make wave-induced vibrations more dominant in its design. During idling phases of these next-generation OWTs, additional damping is required. This can be achieved through dynamic vibration absorbers (VAs), i.e. dampers. More importantly, wave...master thesis 2017

De Valk, P.C. (author)The demand for energy will continue to increase in the coming years and offshore wind energy shows great potential to become a key player in Europe’s renewable energy future. The wind flow offshore is more stable and the average wind velocity is higher than onshore. Moreover, no size restriction exists for offshore wind turbines. However, the...master thesis 2013
