CASE STUDY
Mitsui O.S.K. Lines, Ltd. (MOL) has obtained Approval in Principle (AiP) for a new LNG carrier equipped with four hard sail wind propulsion systems, known as "Wind Challenger." This project is a joint development effort with South Korea's HD Hyundai Heavy Industries (HHI) and Samsung Heavy Industries (SHI).
The new vessel design maximizes fuel efficiency by positioning the bridge at the front of the hull, allowing for an increased number of Wind Challenger units and optimized placement. This contributes significantly to reducing fuel consumption and greenhouse gas (GHG) emissions.

MOL is advancing plans to deploy 25 vessels equipped with Wind Challenger units by 2030 and 80 vessels by 2035, as part of its commitment to achieving net zero emissions by 2050. This project promotes the development of next-generation vessel designs utilizing wind energy as part of MOL's low- and zero-carbon technology initiatives aimed at reducing environmental impact.
An exhibition and AiP presentation ceremony for this project were held at the "Gastech Exhibition & Conference 2025" in Milan, Italy, from September 9 to 12, 2025. Highlights from the event are available here:

Mitsui O.S.K. Lines (MOL) has developed the Wind Challenger, which converts wind energy directly to a vessel propulsion force through an extensive use of the latest technologies. Wind energy is clean and unlimited. We aim to drastically reduce greenhouse gas emissions by converting wind energy to propulsion force for ships. In October 2022, the 1st vessel, “SHOFU MARU” was delivered and started operation.
This is an ultimate zero emission project under the Wind Challenger Project, currently in progress with MOL.
Offshore wind energy from sails is used not only as a propulsive force for the vessels, but also for the generation of hydrogen. We are studying ways to supply hydrogen to users on shore by combining this system with fuel cell, etc.
