Three new Windfamrm Support Vessels (WSV) built to BMT Nigel Gee designs launched in 10 days from three different shipyards. The vessels range from a 19.4m propeller driven conventional catamaran design to a 26m Extreme Semi-Swath (XSS), fitted with active motion damping systems consisting of T-Foils and interceptors. Sea trials for two of the vessels have been completed, both of which have met all expected performance criteria. The XSS is currently in transit to the open sea in order for trials to commence in the coming weeks.
