Veršnik, Ana (author)The success of offshore wind farm installations is often related to the costs and time taken to be completed. Current installation strategies require several critical offshore lifts for the completion of a single wind turbine, as in most cases each component gets installed separately. This is time-consuming and has a direct link to the cost of...master thesis 2023

Dach, Florian (author)The amount of floating offshore wind farms under development has drastically increased over the past years as the technology becomes viable for pre-commercial and commercial scale projects. Projects of this size require a streamlined, efficient production of the complete floating offshore wind turbine (FOWT), not only for manufacturing the...master thesis 2023

van Heusden, Joep (author)Due to the growing demand for offshore wind energy and the increasing wind turbine sizes, a shortage of capable installation vessels is anticipated by 2024. Consequently, the utilisation of heavy-lift vessels, previously not employed for bottom-founded or floating offshore wind turbine installations, may become imperative to realise the offshore...master thesis 2023

Jongkees, Eduard (author)The demand of offshore wind energy has increased enormously in the last decade, and continues to do so in the foreseeable future. The monopile will remain the most important foundation structure. There is however not yet a durable solution for its main disadvantage; the under water sound radiation during installation. In this report a new,...master thesis 2023

Li, M. (author)Europe’s offshore wind capacity is expected to reach 450 GW by 2050, meeting 30% of Europe’s electricity demand. With the increase of installed capacity, the costs invested in O&M will also increase significantly considering O&M cost is one of the biggest contributors to life cycle costs. The improvement of O&M management for...doctoral thesis 2023

JIANG, XINJIAN (author)The Wadden Sea is a unique and ecologically important coastal region<br/>in the southeastern North Sea, stretching along the coasts of Denmark,<br/>Germany, and the Netherlands. It is known for its vast tidal flats, salt<br/>marshes, and barrier islands, forming a dynamic and constantly changing<br/>landscape, creating rich biodiversity.<br/><br...master thesis 2023

Ubbens, Martiene (author)Ambitions to limit climate change are incentivizing the expansion of renewable energy. In particular, offshore wind energy is expected to grow rapidly. To harness the full potential of existing as well as prospected offshore wind farms, the limited capacity of the internal cable network of the offshore wind farm, called the collector system,...master thesis 2023

Dekeyser, Ruben (author)To meet global green energy targets, the bottom founded offshore wind industry is looking for ways to economically expand markets to deeper waters. A reduction of the hydrodynamic load is necessary to achieve this. One option is to perforate the monopile around the splash zone. Here the related work of Q. Star is continued through the...master thesis 2023

de Ruiter, Jop (author)In recent years the global energy demand has rapidly increased and will continue to grow in the next decades. With the growing demand for energy and the international agreement to use more renewable energy, the offshore wind industry is developing rapidly. This causes offshore wind farms to be installed at locations with larger water depths and...master thesis 2023

Filippidis, Iason (author)Energy transition is imperative to effectively address the pressing issue of climate change resulting from global warming. In this transition, offshore wind power assumes a pivotal role as a crucial and indispensable source of clean and renewable energy. Offshore benefits become more pronounced as the offshore locations progress far offshore. In...master thesis 2023

Appert, Loïc (author)Due to the increasing size of offshore wind turbines, the jack-up vessels and cranes installing them need to increase in size. The increase in length of the crane boom results in an increase of the dynamic response of the crane. This increase in response results in higher loads in the crane. The magnitude of the higher loads are unknown and not...master thesis 2023

WU, KANGJIE (author)The research on sustainable energy is growing, among which, wind energy catching growing attention and the potential has been supported by more and more countries. Compared with onshore wind farms, offshore wind farms have more advantages including the abundant wind resource at the offshore location and more possible construction areas. While...master thesis 2023

van Suijlen, Quint (author)The increased consciousness of the negative impact of human-induced climate change has resulted in rapid developments within the offshore wind industry. With Wind Turbine Generators (WTGs) becoming increasingly larger and available shallow water sites becoming scarcer, new offshore wind solutions must be developed to accomplish the goals set by...master thesis 2023

Rengarajan, Sudharsan Bharatwaj (author)The hunt for new methods to harness wind energy is at an all-time high as wind energy quickly overtakes other renewable energy sources. Deep waters are promising alternatives with higher average wind speed (thus, higher yields) and also due to lesser availability of land on shore. Even though the design of the blades and rotor of a FOWT is...master thesis 2023

A Multi-Objective Optimization Model for Offshore Wind Farm Operations & Maintenance Fleet SelectionBloothoofd, Jesse (author)Until recently, tenders in Europe were awarded to wind farm developers based on the highest auction prices or the lowest subsidized bids. The wind industry has suggested that non-price-related criteria should be considered for tenders, like plans to reduce greenhouse gas emissions. As a result of the sustainable tender criteria, greenhouse gas...master thesis 2023

van der Tholen, Max (author)Floating offshore wind turbines offer opportunities to harvest wind energy at deep-water locations, where the construction of fixed-base turbines is infeasible. The dynamic power cables, which interconnect turbines and transport the generated electricity, are under large dynamic stresses due to the environmental loads and the motion of the...master thesis 2023
