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

Tiwald, Philipp (author)Global warming represents the most significant threat to humankind, making the need for renewable energy more crucial than ever. However, in densely populated areas near the coast, electricity production faces competition from various sectors such as agriculture, housing, and tourism. To address this challenge, one viable solution is to explore...master thesis 2023

Wille, Seppe (author)Offshore installation vessels are growing in size in order that they are capable of handling the next-generation 15 and 20MW wind turbines. At the same time, it is important to gain a better understanding of their structural behaviour using the finite element (FE) method. One approach that is often used is the full vessel FE analysis, which...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

Slingerland, Bas (author)Mammoet is developing a new type of system for the transportation of offshore power cables. With this system the cables can be spooled, stored, and transported both on land and on heavy transport vessels in a more efficient way. There are a few uncertainties for the system, mainly about the loads on the carousel and the behavior of the cable...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

Bziker, Farah (author)Traditionally, the control point (CP) of a dynamically positioned vessel is located around its center of gravity (CoG). However, during offshore operations, other locations, such as the crane tip or gripper position, become more critical due to the load being located there. This thesis proposes shifting the control point from the CoG to an...master thesis 2023

Schuijt, Rinus (author)In this thesis, the friction performance of polyurethane tensioner pads used in offshore pipe-laying was investigated. Tensioner pads are used in pipe-lay to create tension in a pipe. The need to understand the pads better is because of the increased use of pipe coatings and pipe lay in deeper waters. Deep water leads to more pipe tension, and...master thesis 2023
