AiP for Jones Act compliant WTIV design

Polish/U.S. marine architect Ned Project has been awarded Approval in Principle (AiP) by classification society ABS for its hydrogen-ready wind turbine installation vessel (WTIV) design.

The NP20000X ULAM design is intended to be Jones Act compliant and able to meet future offshore wind market demands, specifically operations involving 15- to 20-MW wind turbine installations. Under the Jones Act, ships operating in U.S. domestic waters must be built in the United States.

The vessel is designed to be equipped with a leg encircling heavy cargo crane with a working load of 3,500 tonnes capable of handling turbines of 240m rotor diameter and 150m tower height. The installation vessel's concept allows to load monopiles vertically on the 8,000m2 deck, eliminating the need to rotate monopiles to the vertical position at sea, aiming to increase efficiency and safety. The WTIV is designed to be hydrogen-ready with the engine rooms able to be converted into fuel cell compartments accommodating polymer electrolyte membrane fuel cells.

Ned Project is working with GPZ Energy to develop projects for the U.S. market.
