New Fjellstrand designed WindServer Trimarans for World Marine Offshore to be classed by GL. As offshore wind developments move further offshore, into deeper waters with more extreme weather conditions, the challenge of providing operations and maintenance (O&M) support safely and cost effectively grows. The Fjellstrand WindServer is one of the new generation of offshore service vessels that will be meeting these needs and Germanischer Lloyd (GL) will be supporting this growing industry by providing classification services for the first newbuildings.
