CSD Hydrodynamics: An analysis of a CSD in coastal conditions, and the effect of flexible spud keeper configurations on the hydrodynamic response

Cutter suction dredgers (CSD) are highly vulnerable to large wave loading due to their stiff, spud-based mooring. Many mitigations targeted at reducing the resulting stresses on the spud and other critical operating components have been proposed in recent years, most notably by adding a level of flexibility to the connection between the pontoon...

Operability Analysis of Wind Farm Maintenance with the Damen FCS2610

The Damen Twin Axe Fast Crew Supplier (FCS)2610 is an offshore wind farm maintenance vessel that can safely and efficiently transfer mechanics between land and a wind farm. The thesis objective is to research the operational capability of the FCS by gaining insight into the push docking procedure of the transfer process. To keep the vessels bow...

Identification of response amplitude operators for ships based on full scale measurements

Heerema Marine Contractors (HMC) operates several crane vessels, barges and tug boats for the transportation, the installation and the removal of offshore facilities. To achieve safe and successful projects, the accurate prediction of vessel motions is of great importance. Vessel motions are calculated on the basis of wave energy spectra and...

A highly versatile autonomous underwater vehicle with biomechanical propulsion

An autonomous underwater vehicle with a biomechanical propulsion system is a possible answer to the demand for small, silent sensor platforms in many fields. The design of Galatea, a bio-mimetic AUV, involves four aspects: hydrodynamic shape, the propulsion, the motion control systems and payload. The shape of the hull is based on a modified...
