Damen Shipyards has unveiled a new Wind Farm Service Vessel (WSV) to support and accommodate turbine maintenance crews at sea and allow them to “walk to work”. The vessel has been designed from first principles to provide on-site work facilities and accommodation for 45 maintenance plus 15 crew personnel for voyages of up to one month.

Damen’s new WSV is a monohull vessel with bridge and accommodation located amidships. With a 90 m length overall and a beam of 20 m, it will feature 500 m2 of deck space, a helideck and a motion and heave compensating crane. Its shallow 4.6 m draft optimizes comfort, while also conferring significant power savings. The dynamically positioned (DP2) WSV will include a telescopic, motion-compensated gangway. This will allow each three-man maintenance team to walk quickly and safely between vessel and turbine.

“At distances greater than 30 nautical miles, maintenance crew transfer from shore within one day becomes both impractical and costly. When we sought market views on a larger support vessel, potential customers set us an 80 % availability target for maintenance crew transfer in wave heights of up to 3 m,” says Peter Robert, Damen Business Development Manager, Offshore Wind.

Designed to drop all seven maintenance crews within three hours, the vessel will remain within range to provide support and emergency assistance through the working day before pick up. Special attention has been paid to interiors and onboard service space lay-out. Public spaces have been mapped for efficient workflows and storage, while 60 single occupancy cabins, a fitness centre and internet/movie services will benefit life at sea.

“Judging by initial feedback, this vessel will make a significant impact on this specialized market,” says Robert.
