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 the production unit. Single point mooring systems will weathervane...

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 during installation of various jacket geometries. This need brings...

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 installation of the substructures and turbines. However, the jacking...

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 attempts to model a CSD in operation have been limited to the frequency...
