Through detailed analysis of the offshore wind industry’s marine challenges and requirements – a unique vessel has been developed. Windkeeper is a small waterplane area twin-hull (SWATH) specifically developed to minimize movement in the vessel during operation and ensuring market-leading comfort for technicians. The hull’s characteristics ensure operability second to none, with gangway performance in +4.0m Hs. Further the design ensures comfortable living spaces for 40 technicians, all in single cabins.
