World's First Test Operation Starts of Large-Bore Low-Speed Ammonia Dual Fuel Engine Equipped with MET Turbocharger

Mitsubishi Heavy Industries Marine Machinery and Equipment Co., Ltd. (MHI-MME) delivered a MET turbocharger for large-bore low-speed ammonia dual fuel engine (MAN ES 7S60ME-C10.5-LGIA-HPSCR) manufactured by MITSUI E&S Co., Ltd. (MITSUI E&S) in November 2023.

On February 10, 2025, MITSUI E&S started the world’s first test operation of large-bore low-speed ammonia dual fuel engine at its Tamano Factory. This engine is equipped with a MET66MBII optimized for ammonia dual-fueled engines.

In the field of international shipping, the reduction of greenhouse gas (GHG) emissions is becoming an important issue, and the development of ammonia-fueled engines, which enables the reduction of CO₂ emissions to zero, is a major step towards the realization of a carbon neutral society.

MHI-MME will continue its efforts as a turbocharger manufacturer to contribute to the realization of a carbon neutral society by providing our customers with optimal, environmentally friendly solution.
