Chevron to deploy MOL’s Wind Challenger propulsion system on “world first” new-build LNG vessel

(WO) – Chevron Shipping Company LLC (Chevron), a subsidiary of Chevron U.S.A. Inc., and Mitsui O.S.K. Lines, Ltd. (MOL) announced an agreement to install Wind Challenger, a hard sail wind-assisted ship propulsion system developed by MOL and Oshima Shipbuilding together (Note 1), to a new-build LNG carrier. This vessel will mark the world’s first LNG carrier equipped with Wind-Assisted Ship Propulsion Systems.

The vessel is under construction at the Geoje Shipyard of Hanwha Ocean Co., Ltd. and is scheduled for delivery in 2026. In August 2024, MOL obtained an approval in principle (AiP) by Nippon Kaiji Kyokai (Class NK) – a first for an LNG carrier with a Wind-Assisted Ship Propulsion System (Note 2). The Chevron chartered vessel will be the first application.

Wind Challenger will help reduce fuel consumption and GHG emissions by using its unique telescopic sails.

In addition to the robust design of Wind Challenger itself, additional safety measures include a fully enclosed navigation bridge and a lookout station on the vessel’s fore deck to further enhance visibility.

For tradability, the installation position of the Wind Challenger aims to minimize impact on the existing design of membrane type LNG Carriers. It will enable the retention of the existing mooring arrangement unchanged and thereby minimize impacts on ship shore compatibility, together with limited impact on the vessel’s windage area.

“We’re proud to partner with MOL in Wind Challenger’s industry-first LNG installation,” said Barbara Pickering, President of Chevron Shipping Company. “This is another example of using novel approaches in hard-to-abate sectors to reduce carbon intensity in our LNG fleet.”

Takeshi Hashimoto, President, and CEO of Mitsui O.S.K. Lines, said, “Achieving GHG reduction in the maritime transport of LNG, which is increasingly in demand worldwide as a transition fuel, is a very important mission for us. This project will undoubtedly be a significant milestone towards achieving 'net-zero emissions by 2050', a medium to long-term goal of the Mitsui O.S.K. Lines Group, as stated in our 'Environmental Vision 2.2'.”

The Wind Challenger technology will be on exhibit at the MOL booth at the Gastech Exhibition & Conference 2024 in Houston, September 17-20. Information sessions on how the technology can be applied to both LNG carriers and other vessels will also be held.
