A parameter sensitivity study for a Soft Yoke Mooring System (SYMS)
Developing a design tool
Floating production units require to be permanently moored offshore. For shallow water field developments, typical designs include soft yoke mooring systems which is a single point mooring technology. Produced fluid is transported via a geostatic tower along the transfer hoses to

Floating Jacket Installation
A parametrized motion prediction model for jacket installation
Contrary to a one-off jacket installation where a contractor can wait for favourable weather conditions, the installation of support structures for offshore wind turbines is of repetitive nature. This repetitive nature leads to a need for a better understanding of the behaviour d

Coupled Dynamics of a Dual Lift Operation
Upending Method of an XXL Monopile
Offshore wind farms are moving to deeper waters, implying that larger substructures will need to be installed. The monopile is the leading substructure nowadays and this structure could be promising for use in deeper waters as well. Generally, jack-up vessels are used for the ins

The fatigue strength of the pin connection is assessed in the research project presented in this thesis. The fatigue strength is quantied by an estimated fatigue lifetime, which is the expected time to failure of the most critical point in the connection. The lifetime is estima

Development of a numerical model for Cutter Suction Dredgers
A time domain analysis of a CSD in operation
A Cutter Suction Dredger (CSD) is a vessel that is used to cut hard soils with precision. It is moored stiffly through a spud pile while the soil is being cut. This, in combination with wave loads, causes the whole system to be dynamically challenging and nonlinear. Previous atte
