Soil – Anchor Interaction of a Floating Offshore Wind Turbine under Cyclic Load

The rapid growth of Floating Offshore Wind (FOW) has spurred intensive research across various aspects of the floating system. A standard practice in mooring system design within the industry is that anchors remain fixed on the seabed. In contrast, plate-type anchors exhibit mobility under loading, a crucial factor considering the thousands of...

Soil-Monopile Interaction: from Elastic to Elastoplastic soil reaction modelling under Quasi-Static Monotonic Loading

Offshore wind energy's rapid expansion underscores the need for accurate and efficient methods to analyze the behavior of monopile foundations supporting wind turbines. While three-dimensional (3D) analyses provide comprehensive insights, their computational demands are significant. As an alternative, one-dimensional (1D) models with spring...

Hydraulic response of the Rhine-Meuse delta to Delta21: The effect of implementing Delta21 with a modified Maeslantkering on water level statistics in the Dutch delta region

The Dutch Rhine-Meuse delta is expected to require many dike reinforcements on a short and long term, due to (accelerated) sea level rise. Average damage in unembanked areas will increase too, and a costly replacement of the Maeslantkering is expected after 2070. Delta21 is a project that aims to address these challenges related to flood...

Free Infragravity Waves and their Effect on Coastal Dune Safety

The coastal safety of the dunes are of high importance for low laying countries (Chen et al., 2017). This is especially true for the Netherlands as it is used officially as a safety measure against flooding from extreme weather since 1984 (Rijkswaterstaat, 1989). As of current 1D modelling of the waves is an acceptable method for the Dutch coast...

Determining the effects of a hydropower dam and climate change on salt intrusion in the Gambia estuary up to 2100

Due to climate change, temperatures are rising worldwide resulting in sea level rise, higher evaporation and possible changes in precipitation patterns. These effects of climate change influence salt intrusion, particularly by affecting the freshwater supply. In The Gambia also a planned hydropower dam and possibly future irrigation development...

Response of an Offshore Wind Turbine supported by a Non-Local Winkler Foundation: An Efficient 1D Time-Domain Model accounting for the 3D Frequency-Dependent Dynamic Soil Stiffness

With increasing evidence of human-induced accelerated climate change, the need of sustainable, non-polluting, energy sources becomes evident. Offshore wind generated electricity is currently one of the most promising sources of energy to create a sustainable global energy mix. The offshore wind industry has developed rapidly over the last years....

Development of a Reliable and Efficient 3D Calculation Model of a High-Rise Building Under Seismic Loading

This thesis research focusses on the development of a reliable and efficient 3D calculation model of an existing high-rise, reinforced concrete building in the Groningen area, in order to analyse the dynamic behaviour of the existing and subsequently retrofitted main bearing structure of this high-rise building. The assessment of the existing...
