Mitsui E&S Group has completed the factory acceptance test (FAT) of Japan’s first WinGD methanol dual-fuel large marine engine, the company announced on 3 August.

The engine, designated the DU-WinGD 6X82DF-M-1.0 LP-SCR, was manufactured by Mitsui E&S DU Co., Ltd., a group company of Mitsui E&S Co., Ltd., at the Tamano Works facility — also marking the first WinGD large marine engine to be produced at the site. It is scheduled to be installed on the lead vessel in a series of four ships being built for a domestic shipowner.

Mitsui E&S explained that production of the engine at Tamano Works was made possible through the group’s relationship with licensors Everllence and WinGD, combined with Tamano Works’ next-generation fuel supply facilities and large marine engine production capacity.

Mitsui E&S added that the development forms part of broader efforts to enhance production efficiency for large marine engines through integrated operations between Mitsui E&S Tamano Works and Mitsui E&S DU Aioi, with those efforts aimed at meeting anticipated growth in marine engine demand in line with the Japanese government’s Shipbuilding Industry Revitalization Roadmap.

The 6X82DF-M-1.0 LP-SCR engine uses a low-pressure selective catalytic reduction (LP-SCR) system to reduce nitrogen oxide (NOx) emissions and is designed to run on both conventional fuel oil and methanol, offering operators flexibility as the industry transitions toward lower-emission fuels.
