Osaka, Japan (September 16th, 2021) – Yanmar has received an order for dual fuel 6EY22ALDF engines which will be used to power generators on board a LNG-fueled large coal carrier to be operated by Mitsui O.S.K. Lines, Ltd. The coal carrier will be built by Namura Shipbuilding Co., Ltd.
Emission regulations in the marine sector are becoming ever more stringent, with LNG vessels being adopted globally as a means of reducing environmental impact. As this trend has progressed in recent years, dual fuel engines have attracted ever more attention. Their ability to run on both diesel and environmentally friendly LNG allows them to satisfy International Maritime Organization (IMO) Tier 3 regulations whilst also reducing greenhouse gas (GHG) emissions.
Yanmar will continue its efforts to reduce marine engines’ environmental impact and develop clean marine powertrains to provide optimal solutions that meet the needs of our customers.
