“K” Line Wind Service, LTD. (“K” Line Wind), a joint venture between Kawasaki Kisen Kaisha,
Ltd. and Kawasaki Kinkai Kisen Kaisha, Ltd., has signed an agreement with Japan Marine United
Corporation (JMU) for a commissioned study on efficient mooring construction methods as part
of its participation in the Development of the Southern Akita Floating Offshore Wind
Demonstration Project Aimed at Overseas Expansion via Cost Reductions, (the Project). The
project is a part of the New Energy and Industrial Technology Development Organization
(NEDO)'s Green Innovation Fund Project* ¹ /Cost Reductions for Offshore Wind Power
Generation/Floating Offshore Wind Power Demonstration Project (Phase 2).
JMU received formal notification of the approval of the NEDO grant for the Project. The Project
is being conducted by a consortium led by Marubeni Offshore Wind Development Corporation,
with the participation of JMU, Tohoku Electric Power Co., Inc., Akita Floating Offshore Wind
Corporation, TOA CORPORATION, TOKYO SEIKO ROPE MFG. CO., LTD., Kanden Plant
Corporation, JFE Engineering Corporation, and NAKANIHON AIR Co., Ltd. The main objectives
of the Project are to install two 15 MW-class wind turbines in the southern offshore region of
Akita Prefecture, to address technical challenges related to the mass-production method of
floating foundations and to reduce the cost of installation.
“K” Line Wind has been involved in phase 1 of the Green Innovation Fund Project/Cost
Reductions for Offshore Wind Power Generation/ Floating Foundation/Low-Cost Installation
Technology Development Project (2021–2023) and conducted intensive research for efficient
mooring methods for large-scale Floating Offshore Wind farms.*² As a result of these efforts, in
February 2024, “K” Line Wind, JMU, and Nihon Shipyard Co., Ltd. have announced the
approval in principle (AiP) for the design concept of the multi-functional floating offshore windfarm
support vessel. *³ Additionally, in September 2024, the company published the Guidelines for
the Towing and Mooring Installation of Floating Offshore Wind Power Equipment in collaboration
with the Nippon Kaiji Kyokai (ClassNK).*4 The work commissioned in phase 2 builds on the
mooring installation technologies developed in phase 1, advancing them for their practical
application in commercial-scale projects.
To efficiently install large-scale floating wind turbines, specialized vessels suitable for Japan's
unique maritime and weather conditions must be used. “K” Line Wind, in collaboration with JMU,
is dedicated to the research and development of efficient mooring installation techniques, with
the aim of reducing costs and improving the construction efficiency of floating offshore wind farms.
“K” Line Wind will continue to be committed to contributing to the development and
implementation of floating offshore wind power technologies through its research and
development efforts. The company aims to promote the large-scale deployment of floating
offshore wind power generation systems and the reduction of their cost while also contributing
to the realization of a low-carbon and decarbonized society
