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

Schipper, Jurrien (author)Modelling of Floating Offshore Wind Turbines (FOWTs) is challenging due to the strong coupling between the aerodynamics of the turbine and the hydrodynamics of the floating structure, which makes the dynamic response of the whole system highly complex. A variety of numerical approaches can be used to predict this response.<br/><br/>The frequency...master thesis 2023

van Delzen, Timo (author)Offshore bidding zones will eventually result in lower revenues for offshore wind farm owners due to a lower electricity volume and price risk, especially when flow-based market coupling and advanced hybrid coupling are implemented in the electricity system. This results in a demand to improve the investment climate for offshore wind farm owners...master thesis 2023

Seismic response of jack-ups: An improved earthquake screening procedure using time history analysisLatooij, Sean (author)Jack-ups are used for offshore wind turbine installation (OWTI). To assess whether a jack-up can safely operate in a desired geographic location with known seismic activity, an earthquake response analysis is required for structural verification. This analysis is generally carried out according to the codes of the International Organization for...master thesis 2023
