Dutch Offshore Innovators BV has developed a concept for an installation vessel for offshore wind turbine foundations. Following market research it was decided to develop a compact yet multi functional vessel. The vessel is capable of installing monopile/transition piece foundations as well as jacket type foundations. Deck layouts tailored to installation of the various tasks have been developed to optimize the installation operations. Technology for this has partly been borrowed from the offshore Oil and Gas industry. Particular attention has been paid to the operability of the vessel. Extensive research has shown that an innovative hull shape in combination with active roll reduction will result in a very high operability percentage. Cost calculations have been carried out to establish the capital cost as well as the operational cost of the vessel. A comparison shows that savings of up to 50% on the cost of foundation installation work are possible.
