Kerkhof, Joost (author)Offshore wind energy is a pivotal element in the renewable energy transition and achieving net-zero emissions by 2050. Most offshore wind turbines require the installation of a sturdy foundation called a monopile. The current method of installing monopiles offshore is known as piling, which involves driving large steel cylinders into the seabed...master thesis 2024

Woudstra, Jelle (author)In an era where global energy consumption has been rising steadily, the demand and supply of renewable energy sources have become increasingly important. Offshore wind is a promising renewable energy source, which has been actively developed in the last decades in the form of bottom-founded offshore wind, bound to shallow water. Floating...master thesis 2024

Kayadibi, Turhan (author)Gravel is a material with multiple purposes in construction and infrastructure. Its usage ranges from construc-tion of roads, building navigational channels to land reclaimation. Gravel can be obtained through multiple methods, such as dredging with ships. One of such dredging ship is the trailing suction hopper dredger (TSHD). However, in the...master thesis 2024

Kolset, Alexander (author)In recent years, there has been growing interest in exploring the deployment of wave energy converters (WECs) in remote and harsh environments. However, research in this area remains limited, particularly concerning offshore environments with sea ice. This study focuses on investigating the energy production and economic feasibility of a point...master thesis 2024

Mezilis, Lefteris (author)The European energy transition policies aim to mitigate the effects of climate change by moving away from fossils and promoting both onshore and offshore renewable energy technologies. Although onshore renewables are driving the transition so far, policymakers believe that in order to achieve the targets, the power grid must have access to the...master thesis 2024

de Koning, Daan (author)When drag anchors are no longer suitable for anchoring floating wind turbines to the seabed because of unfavorable soil conditions, it is necessary to use drilled and grouted anchor piles instead. For the installation of such anchor piles it is necessary to drill large diameter holes, with diameters ranging between 1 and 5 meters. The drilling...master thesis 2024

Twigt, Tom (author)The European offshore wind industry has experienced significant growth in the past decade, mainly focusing on shallow areas in the North Sea to reduce the Levelised Cost of Electricity (LCoE) and compete with fossil fuels. However, as shallow areas become scarcer and the industry seeks greater independence from government subsidies, a shift...master thesis 2024

Dekkers, Wout (author)Steel is a widely used material in construction because of its availability, high strength-to-weight ratio, and recyclability. However, steel manufacturing consumes a lot of energy, and there is an increasing demand for more environmentally friendly building materials. Consequently, high-strength steel is becoming more popular as it reduces the...master thesis 2024

Oosterholt, Torsten (author)Founded in 1910, Boskalis, a leader in offshore operations, contends with limitations in ABB's Ability Marine Advisory System 'OCTOPUS' in predicting maximum vessel motions for heavy-transport vessels (HTVs). Accurate prediction of these motions, especially roll and pitch, is vital for transporting large, heavy structures, as exceeding...master thesis 2024

Mulder, Ernst (author)The offshore wind industry is increasingly constructing wind turbines farther from the coast, in deeper water, and under more extreme conditions. This requires larger (monopile) foundations and necessitates new installation methods. An important factor affecting workability is the dynamic behavior of the monopile during installation. <br/>The...master thesis 2024

Holsappel, Tim (author)<br/>In response to the escalating demand for renewable energy, wind turbines and their support structures have witnessed exponential growth in size in recent decades. However, this expansion presents substantial challenges, particularly in the face of severe storms and large waves, raising concerns about resonance-related issues. Accurate...master thesis 2024

Rupprath, Sarah (author)One of the key challenges for offshore pipeline installation are free spans, which are sections not supported by the seabed. Within these sections the stress in the pipeline is increased due to local buckling which is caused by high bending moments at free span shoulders and midspan. Additionally, hydrodynamic loading due to currents and waves,...master thesis 2023

Kweldam, Edwin (author)The increase of demand for offshore wind energy resulted in an increase of larger wind turbines. These turbines are often placed on top of a monopile (MP) substructure. The conventional method for installing these MPs uses a jack-up vessel. However, due to the local bathymetry and soil conditions. This method has its drawbacks, such as...master thesis 2023

Koorn, Niels (author)The electric pulse fishing technique is no longer an option for fishermen. Therefore, they have to fall back on beam trawl fishing. This method has several disadvantages such as high fuel consumption and much soil disturbance. This system therefore deserves an investigation into improvement.<br/>There is various literature on interaction of...master thesis 2023
