MITSUI E&S on Monday (3 August) announced that Mitsui E&S DU, a group company of MITSUI E&S, has successfully completed the Factory Acceptance Test (FAT) of the DU-WinGD 6X82DF-M-1.0 LP-SCR, the first methanol dual-fuel WinGD large marine engine built in Japan. The engine is also the first WinGD large marine engine manufactured at MITSUI E&S Tamano Works. “The engine is scheduled to be installed on the first vessel in a series of four vessels being built for a domestic shipowner,” the company said on its website. By utilising green methanol as fuel, it will contribute to a substantial reduction in greenhouse gas (GHG) emissions from shipping operations. “To meet the expected increase in marine engine demand under the Japanese government’s Shipbuilding Industry Revitalisation Roadmap, the MITSUI E&S Group is working to enhance production efficiency for large marine engines through integrated operation at MITSUI E&S Tamano and Mitsui E&S DU Aioi,” the company added.   Photo credit: MITSUI E&S Published: 4 August, 2026
