Kawasaki Kisen Kaisha, Ltd. and K Line Wind Service Co., Ltd., a joint venture company of Kawasaki Kisen Kaisha, Ltd. and Kawasaki Kinkai Kisen Co., Ltd. (hereinafter referred to as "K Line Wind Service"), have signed a contract for commissioned work regarding the investigation of 'efficient mooring construction methods' within the 'Akita Prefecture Southern Offshore Floating Wind Power Demonstration Project' aimed at overseas expansion through cost reduction as part of the 'Green Innovation Fund Business (Note 1) / Cost Reduction of Offshore Wind Power Generation / Floating Offshore Wind Power Demonstration Project (Phase 2)' adopted by Japan Marine United Corporation (hereinafter referred to as 'JMU').
JMU received a grant decision notice as a research and development contractor for this project, in which each base in the Akita Prefecture Southern Offshore aims to install two wind power generators with a capacity of over 15MW, focusing on mass production of floating foundations and solving technical challenges to achieve low installation costs. JMU included Marubeni Offshore Wind Power Development Co., Ltd. as the lead company, along with JMU, JFE Engineering Corporation, Tokyo Seiho Sengyo Rope Co., Ltd., Akita Prefecture Southern Offshore Floating Wind Power Joint Company, Tohoku Electric Power Co., Ltd., Toa Corporation, Kanden Plant Co., Ltd., and Chubu Nippon Airlines Co., Ltd. as research and development entities of this project.
K Line Wind Service has been involved in the 'Green Innovation Fund Business / Cost Reduction of Offshore Wind Power Generation / Floating Foundation Manufacturing and Installation Cost Reduction Technology Development Project (Phase 1)' from 2021 to 2023. As a result, in February of this year, JMU, along with Japan Shipyard and others, announced the acquisition of AiP certification for a dedicated ship concept for floating offshore wind turbines (Note 3). In September, in collaboration with the Japan Ship Machinery Association, they issued and disclosed the 'Guidelines for Towing and Mooring Construction for Floating Offshore Wind Power Facility Construction' (Note 4) created. The commissioned work from JMU in Phase 2 is aimed at further developing the mooring construction technology that was cultivated during the research and development in Phase 1 for practical application in commercial-scale projects.
To efficiently install large floating wind turbines, mooring construction of wind turbine floaters using workboats suitable for Japan's marine meteorological conditions is required. K Line Wind Service is collaborating with JMU to research and develop efficient mooring construction technology, aiming to reduce the cost of wind turbine floater installation and increase the efficiency of floating offshore wind farm construction. Through research and development contributing to the construction of floating offshore wind power facilities and their social implementation, they aim to contribute to the large-scale introduction and cost reduction of floating offshore wind power facilities and to the decarbonization of society.
