Mitsui O.S.K. Lines, Ltd. (MOL)  announced today the successful completion of seven round-trip voyages by the Shofu Maru, the world’s first coal carrier equipped with the innovative Wind Challenger hard sail wind propulsion system. Since its delivery in October 2022, the vessel has primarily operated between Japan and Australia, Indonesia, and North America, transporting coal for Tohoku Electric Power Co., Inc.

Over approximately 18 months of operation, MOL has continuously measured the performance of the Wind Challenger system. The data confirms that the Wind Challenger sail has reduced daily fuel consumption by up to 17%, with an average reduction of 5% to 8% per voyage. These results align with prior announcements and underscore the system’s potential to enhance fuel efficiency.

MOL has set an ambitious target of achieving net-zero greenhouse gas (GHG) emissions by 2050, as outlined in the “MOL Group Environmental Vision 2.2.” A cornerstone of this strategy is the adoption of advanced energy-saving technologies. The company plans to launch 25 vessels equipped with the Wind Challenger by 2030, expanding to 80 vessels by 2035.

Through the integration of wind propulsion technology and other energy-saving innovations, the MOL Group has built a robust operational framework focused on safety and environmental sustainability. By harnessing natural energy, MOL not only aims to reduce GHG emissions from its fleet but also seeks to contribute to the broader goal of societal decarbonization.

The success of the Shofu Maru represents a significant milestone in MOL’s journey towards a sustainable future. As the company continues to pioneer green shipping technologies, it reaffirms its commitment to leading the maritime industry in environmental stewardship.
