Approval in Principle (AiP) from Japanese Classification Society ClassNK
for the design concept of the Multi-functional Floating offshore windfarm Support Vessel

Japan Marine United Corporation (Japan Marine United) together with Nihon ShipyardCo., Ltd. (Nihon Shipyard) and “K” Line Wind Service, LTD. (“K” Line Wind Service), a joint
venture of Kawasaki Kisen Kaisha, Ltd. and Kawasaki Kinkai Kisen Kaisha, Ltd. have been
jointly granted Approval in Principle (AiP)*1 from Nippon Kaiji Kyokai (ClassNK) for thedesign concept of the multi-functional floating offshore windfarm support vessel (MFSV).
The development of this design concept is subsidized by the New Energy and Industrial
Technology Development Organization (NEDO) as a part of Green Innovation Fund Project“Technology development project for basic manufacturing and installation cost reduction for
floating wind turbines”. *2<Image of MFSV>
The development of floating offshore wind is expected to take an important and key rolein the achievement of the carbon neutral by 2050, especially in Japan where the shallow
water area to develop the bottom-fixed offshore wind turbines is limited.
The installation of floating offshore wind turbines always required mooring works byvessels, with the whole mooring system composed of an anchor, a mooring chain, and afiber rope.
Japan Marine United has been pursuing the study on the most effective mooring method
and the most suitable vessel design for such mooring work together with Nihon Shipyardand “K” Line Wind Service. Finally, we completed the design concept of MFSV andobtained AiP from ClassNK.
This MFSV is designed to perform whole mooring works efficiently for floating offshore
wind turbine installation, like “transportation of mooring system”, “deploying mooring systemon the seabed”, “anchor tensioning”. On top of such primal functions, the uniqueness ismultifunctional concept. This MFSV is designed to provide various vessel solutions in eachphase of an offshore wind projects such as "Survey ", "Transportation", "Construction", and"Operation & Maintenance". (multifunction concept of MFSV is currently under process ofpatent application)
Japan Marine United is determined to contribute to Low-carbon and decarbonization ofsociety by pursuing the provision of offshore support vessels including the design conceptof MFSV for the mass production and cost reduction of offshore wind power generation.
