WIND POWER FOR A FURTHER JAPANESE COAL CARRIER

Apr 20, 2026 | Marine environment & clean shipping news

Mitsui OSK Lines (MOL) and Japanese electric power developer J-Power have installed the Wind Challenger-hard-sail wind propulsion system (developed by MOL and Oshima Shipbuilding on the coal carrier vessel ‘Kurotakisan Maru Ⅲ’.

This marks the world’s first retrofit installation of the Wind Challenger on a vessel currently in service, and is MOL’s third Wind Challenger-equipped vessel, following the coal carrier Shofu Maru and the 64,000 dwt Ultramax bulk carrier Green Winds.

The Kurotakisan Maru is said to have drawn attention in the shipping industry for contributing to decarbonisation while fulfilling a vital role in energy transport that supports local communities. It received a warm welcome from local stakeholders upon arrival at its unloading ports. The vessel is scheduled to operate on a long-term contract to transport thermal coal from overseas to multiple regions where J-Power operates power plants and related facilities.

MOL has set the target of achieving net-zero GHG emissions by 2050 through introduction of further energy-saving technologies. The group plans to launch 25 vessels equipped with the Wind Challenger by 2030, increasing to 80 by 2035.
