DNV updates standards for wind-based propulsion
Classification society DNV has published an update of the technical standards for wind-assisted propulsion systems (WAPS). The standard, called ST-0511, provides a regulatory framework for review and certification of the technologies and can be applied to obtain an Approval in Principle (AiP), design or type approval. The technical standard is an addition to DNV‘s WAPS class notation, which focuses on the integration of systems on board vessels, both retrofit and newbuild. Due to the complex interactions with the ship’s structure, the amended code includes a new section on fatigue strength of WAPS, including calculations to derive the load combinations of wind and inertial forces....
