Meijer, Diederik (author)The offshore wind sector in Europe has grown significantly over the past 20 years. Following this surge in number of installations, the first generation of turbines is reaching its end-of-life (EOL) phase and thought needs to be put into end-of-life strategies. As the market for lifetime extension is still in its infancy and...master thesis 2022

Liu, Shangru (author)In this 3D fracture-based topology optimization framework, the author extended the 2D framework on tailoring fracture resistance for brittle materials (Zhang et al., 2022) to 3D. In the optimization, the topology is described by radial basis functions interpolated level set function, and the problem is solved by the Interface-enriched...master thesis 2022

van Dijke, Laura (author)The Arctic is warming more rapidly than other latitudes, which can result in the release of additional greenhouse gasses, global sea level rise and increase in extreme weather events. Additionally, this causes the rapid decline of sea ice and an ice free Arctic might occur during the summer in the 2040s. The decreasing sea...master thesis 2022

Vehmeijer, Reinoud (author)Subsea rock installation is a process in offshore engineering where rocks are placed on the seabed or subsea structures using a fallpipe. An example of a subsea structure could be a cable or pipeline that must be protected. In this research, the main scope is rock installation for scour protection of the foundation of offshore wind turbines. As...master thesis 2022

Bekkers, Tijs (author)Tidal energy has the potential to be an important and necessary addition to the available sources of energy in the coming energy transition. While there is an extensive body of research on the topic of high tidal resource locations, little research exists on low tidal resource locations such as The Netherlands. The thesis aims to reduce this gap...master thesis 2022

van der Stap, Florian (author)The increasing popularity of offshore wind as a result of the demand for renewable energy, forces the industry to consider the development of wind farms in sub-arctic areas. One of these areas is the Baltic Sea, where the potential for wind energy is very large, but which is also prone to the occurrence of ice. For the design of offshore...master thesis 2022

de Jong, Jasmijn (author)Operational optimization of vessels is valuable for the planning and execution of maritime operations. Accurate and efficient models to predict vessel motions are needed to make reliable operational decisions. The wave-induced vessel response can be modelled in terms of a Response Amplitude Operator (RAO) and a wave spectrum. Uncertainties...master thesis 2022

Veltenaar, Bas (author)In this thesis, an automated buckling check method has been developed and validated for thin plated stiffened structures used in stressed skin topsides.<br/><br/>Thin plated stiffened structures are widely used in, for example, aircraft, bridges and ships. Recently, it has become competitive to use this type of construction to offshore topsides...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

Blom, Ruben (author)The increased awareness of the negative consequences of man-made climate change has given rise to a fast growing offshore wind industry. Wind turbines become increasingly larger, and available locations for offshore wind farms are shifting towards deeper waters, where jack-up vessels can no longer be used for installation. Heerema Marine...master thesis 2022

de Jong, Olivier (author)In contrast to traditional power cables for bottom-founded offshore wind turbines, power cables for floating wind turbines penetrate the water column and are exposed to cyclic loading. Due to the dynamic nature of the cable loading, the cables are prone to fatigue failure. Since the evaluation of the fatigue life of complex structures, like...master thesis 2022

Dobbe, Peter (author)In the field of mining and dredging engineering, oftentimes slurries are involved in transport. Understanding the behaviour of these slurries in a flow is important as the energy and water consumption need to be determined. The slurries have an interesting rheology due to the presence of clay. The rheological parameters cause the flow to be non...master thesis 2022

Kingma, Pieter (author)Floating offshore production units are typically anchored to the seabed with mooring chains. Structural degradation of mooring chain steel can lead to premature failure with large environmental and financial consequences. In the oceanic environment, corrosion and fatigue are the dominant failure modes for mooring chains. These damage mechanisms...master thesis 2022

Mikail, Davey (author)The increasing demand for renewable energy sources, to achieve ‘green goals’ such as the Paris agreement, and their related projects, are becoming increasingly challenging to accomplish. Nowadays, offshore wind farm projects move into deeper waters and require larger individual Offshore Wind Turbines<br/>(OWT’s), which results in larger...master thesis 2022

Rosenboom, Bas (author)As the world economy and population grow, energy consumption grows too at a never before seen pace. Reducing costs and increased environmental awareness resulted in renewable energy sources being the fastest-growing sources in the last decade. Due to its high potential, many offshore wind turbines will be installed in the coming years. These...master thesis 2022

Seegers, Jeroen (author)The slip joint connection is a relatively new alternative method for connecting offshore wind turbine towers to prior installed monopiles. It consists of two overlapping conical sections that together form a connection. There are several challenges left to be solved before the slip joint can be applied on a commercial scale. One of those...master thesis 2022

Hageman, Evelien (author)Over 5000 offshore wind turbine generators have been installed in the past decades. 80% of these wind turbines have a monopile foundation. Monopiles are hollow steel tubular piles with a diameter of up to 10m. The first phase of the monopile installation consists of the self-weight penetration into the seabed due to the mass of the monopile....master thesis 2022

Groenewegen, Rik (author)The first large offshore wind farms installed in the North Sea Region (NSR) soon reach their technical end of lifetime. The wind turbines in these farms will have to be decommissioned after power production has stopped. Currently offshore wind turbines are decommissioned based on a method called reversed installation, a time consuming and...master thesis 2022

Grolman, Wouter (author)The demand for renewable energies is rising due to climate goals and high oil prices. Not only the established renewable sources like wind and solar are interesting to exploit. There is a vast amount of energy stored in the world’s oceans. To harvest this energy, one needs a Wave Energy Converter (WEC). There<br/>are already some prototype WECs...master thesis 2022

Smorenberg, Marius (author)Climate change is triggering an ever-growing demand for renewable energy. The U.S. is still far behind Europe when it comes to offshore wind energy. They have made ambitious plans to reach 30 GW in offshore wind energy by 2030 while currently 42 MW is installed. One of the main challenges in the U.S. is the installation method since a...master thesis 2022
