MOL Expands Wind-Assisted Propulsion to Meet Decarbonization Goals

Mitsui O.S.K. Lines (MOL) is expanding its use of wind-assisted propulsion as part of its decarbonization efforts, with test results from the first vessel fitted with their rigid sail after 18 months of operation. They are also considering other technologies and planning their first retrofit of the Wind Challenger to a bulker. The move comes as the technology gains interest from shipowners, with 37 vessels currently using wind propulsion, doubling in the past year.

MOL plans to launch 25 vessels equipped with the Wind Challenger by 2030, increasing to 80 by 2035, with a second bulker set to deploy the sail in June. The sail, made of fiberglass, can retract to reduce air draft and is mounted on the bow. MOL is also exploring additional technologies, such as wind rotors and Ventfoils, to further reduce fuel and GHG emissions on their vessels.

The data from MOL’s first vessel with the Wind Challenger showed up to a 17% reduction in fuel consumption over 18 months, with an average saving of 5-8% per voyage. The upcoming retrofit of the sail to an in-service bulker is expected to further reduce GHG emissions by about 5-8% on specific voyages. MOL is committed to implementing wind propulsion technology to meet decarbonization goals and reduce environmental impact in the shipping industry.
