Mitsui E&S Machinery signs turbocharger license agreement

Mitsui plans to start with three types of MET turbochargers: MET-42MB/42MBII/66MBII and the first one will be launched early 2023. Other types will follow according to market requirements.

Mitsui has manufactured more than 4,000 sets of turbochargers over 40 years since it signed its first license agreement of with MAN Energy Solutions in 1981. It now adds MET turbochargers to its own product portfolio to provide a greater selection for Mitsui-MAN B&W engines and will undertake after-sales services of all MET turbochargers installed on Mitsui-MAN B&W engines as well as those manufactured under the new license.

Mitsui has been manufacturing a single brand of large marine diesel engines ever since concluding a technical tie-up with B&W of Denmark (now MAN Energy Solutions) in 1926. In 2021 the company reached cumulative production of 110 million horsepower, with more than 7,000 units manufactured to date. These statistics make Mitsui Japan’s foremost engine manufacturer and a world leader in the industry.

MHI-MME began marketing water-cooled turbochargers in the 1950s, and in 1965 the company developed the world’s first non-water-cooled turbocharger, a precursor of the MET series. Since then, the lineup has been expanded to include numerous high-efficiency large-capacity models. Today, MHI-MME has a track record in MET turbochargers of more than 39,000 units in total, and the company accounts for a near 40% share of the global market for turbochargers for two-stroke marine engines.

Going forward MHI-MME aims to strengthen its ties with Mitsui E&S Machinery in a quest to further develop business in marine engines and turbochargers taking into account of global warming issues.
