Hard Sail Completed for 'Wind Challenger Project' and Installation Underway on Large-scale Vessel
-Using Wind as Vessel Propulsive Force-

February 01, 2022

TOKYO-Mitsui O.S.K. Lines, Ltd. (MOL; President & CEO: Takeshi Hashimoto) and Oshima Shipbuilding Co., Ltd. (President: Eichi Hiraga; Headquarters: Saikai-shi, Nagasaki Prefecture) today announced the completion of the hard sail system jointly developed under the "Wind Challenger" project at the Oshima shipyard.

MOL have been promoting the Wind Challenger Project to harness wind as a propulsive force for merchant ships. The additional propulsion power from wind can reduce a vessel's greenhouse gas (GHG) emissions by an estimated 5% to 8% compared to conventional ships of the same class. (Note 2)

The hard sail will be installed on a bulk carrier currently under construction at Oshima Shipbuilding after shoreside tests. The vessel is slated for delivery this fall after sea trials and engaged in the transport of cargoes for Tohoku Electric Power Co., Inc..

MOL set out its plan to achieve net zero GHG emissions by 2050 through concerted group-wide efforts in "MOL Group Environmental Vision 2.1" (Note 3). The company will contribute to reduce GHG emissions from society at large, and realize a low-carbon and decarbonized society by proactively participating not only in this project, but also by establishing clean energy supply chains. It will also move assertively to promote wind-related businesses including the Wind Challenger-developed hard sail.

Please stay tuned for updates on the Wind Challenger Project.

The Wind Challenger Project started in 2009 with the "Wind Challenger Plan," an industry-academia joint research project led by The University of Tokyo, and since 2013, the team has been chosen to receive a subsidy on next-generation marine environment-related technology research from Japan's Ministry of Land, Infrastructure, Transport and Tourism. In January 2018, MOL and Oshima Shipbuilding took charge of the plan and now play a central role in this project.
