Tsota, Marinansy (author)Suction caisson jacket (SCJ) is one of the most promising substructures, under certain conditions, for offshore wind turbines. Their unique characteristic of large diameter (D) compared to their small wall thickness (t) conducts them an object of study, concerning their transportation to the offshore location, as their structural stability...master thesis 2023

van Doormaal, Thijn (author)The demand for offshore wind energy has never been higher, yet the number of ideal areas for wind farm installations is decreasing. As a result, larger wind turbines are being placed in deeper waters, which poses opportunities for floating foundations. However, due to the industry's inability to scale up the production of relatively expensive...master thesis 2023

Öhlschläger, Youri (author)Changing the way of power production on a Floating, Production, Storage, and Offloading (FPSO)<br/>system by using renewable power can contribute to reducing an FPSO’s carbon footprint while operating. Bluewater Energy Services is interested in the use of a wind turbine placed on top of an<br/>FPSO, to power the FPSO’s internal electricity grid....master thesis 2022

Rietema, Bertie (author)Offshore structures are often founded on mud-mat foundations which prevent the structure from settling excessively. Pressure differences are generated under mud-mats during removal from the seabed. These differences lead to a force that resists the uplift. A literature study on breakout resulted in a hypothesized distinction of four mechanisms...master thesis 2022

Ursem, Youri (author)To fulfil the ever-increasing need for wind energy, European offshore wind farm sites are selected in deeper waters with seabed conditions which can consist of hard consolidated sediments or even rock. The deeper sites require the use of floating wind turbine foundations that are moored off to anchor piles in the seabed. For rock seabed sites,...master thesis 2022

Castellino, Francesco (author)One of the main cost drivers of an offshore wind power plant are the support structures of the wind turbines, it is therefore of primary importance to optimize their design. Among the support structures available, the concept most widely adopted is the monopile-based support structure, whose design is often fatigue-driven. Offshore structures...master thesis 2022

Schrijvers, Bart (author)This research investigates how the current friction design standard should be improved, specifically for monopile sea fastening with polymers. Literature and results from tests performed previously to this research are investigated in order to obtain a complete overview of the factors that should be considered in the design standard. Additional...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

Stamenkovits, Bela (author)Although modern technologies such as smartphones with GPS functionality make navigation substantially easier, automobilists still rely on traffic signs to inform them which exit to take or which lane to follow. These traffic signs on highways are of substantial size rendering them, and their support structures, extremely susceptible to...master thesis 2022

Solvang, Joar (author)The report summarises the development of a frequency domain Multi-Unit Floating Platform (MUFP) model and a parametric design optimization using the model. The model returns the response statistics of a MUFP due to environmental wind and wave loading using input variables of column separation, column diameter and draft. The model is developed...master thesis 2021

van der Giessen, Matthew (author)The goal of this thesis is to investigate the feasibility of optimizing the mooring line characteristics of a semi-taut (chain – polyester – chain) mooring system in combination with drag embedded anchors for a 12 MW wind turbine supported by a semi-submersible in deep water, based on static analysis of the Ultimate Limit State (ULS) condition....master thesis 2021

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 de Putte, Valentine (author)This thesis project has set out to investigate the response in fore-aft direction of a monopile wind foundation supporting an NREL 5MW turbine, offshore the coast of Taiwan, which is affected by weak to strong earthquake ground motion in combination with normal sea state conditions. The soil at the location of the monopile is layered, with sand...master thesis 2018

Lengkeek, Thijs (author)The wind energy industry is booming. In 2017 the installed wind capacity has overtaken coal as the second largest form of power generation in Europe. Costs of wind farms are driven down, and even the first offshore wind-farm contract without subsidies is a fact. Installing the Wind Turbine Generators (WTGs) more efficiently increases the profit...master thesis 2018

Rapis, Pantelis (author)The monopile is the prevailing foundation concept applied in offshore wind farms, mainly due to construction of offshore wind farms in relatively shallow water. The monopile can provide a technically and financially feasible solution in shallow water environment due to its’ ability to support the wind generator ensuring at the same time the...master thesis 2017

Roozendaal, Maxime (author)Renewable energy generated by offshore wind turbines (OWT) are nowadays more frequently used in the offshore industry. The design of OWT foundations share similarities with a typical offshore oil and gas construction, however a OWT farm usually consist of multiple foundations whose installation are more cost-sensitive compared to one oil and gas...master thesis 2017

Kouka, A. (author)Project Code: OE54015, OE54030. The potential of offshore wind is enormous. The wind resource offshore is generally much greater than onshore, especially at bigger water depths. Expanding prudently into the sea leads to bigger support structures for the wind turbine. Therefore, the need for optimized designs, which will establish the wind energy...master thesis 2016

Sehrawat, N. (author)The present state-of-the-art modelling tools (such as FAST, BLADED) used for modelling an offshore wind turbine (OWT) are too detailed and computationally expensive. These tools are required only at detailed design stages of a project. For the preliminary phase, however, a much simpler (yet reliable) 3D model can improve and speedup the design...master thesis 2016

Beerens, M.A. (author)The latest Conference of Parties at Paris resulted in an important agreement that 27 percent of the total European energy consumption has to come from renewable energy in 2030. Offshore wind energy is an important resource for renewable energy. The shortage of shallow water areas pushed offshore wind farms into deeper waters. Floating Offshore...master thesis 2016
