Marine Propulsion System
As the heart of ships, our mission is to continue the evolution of global marine logistics and transport. While ensuring trusted quality, we aim to become a total propulsion system supplier that continues to support optimal operations by utilizing environmental technology, IoT, and big data. Through our engines with added features, we will contribute to the realization of a decarbonized and recycling-oriented society and the advancement of digital transformation (DX) in maritime logistics.
Marine Engine
Since entering into a technical partnership with Burmeister & Wain A/S (B&W) in 1926, MITSUI E&S has achieved a cumulative production of 120 million horsepower. In addition, with the launch of Mitsui E&S DU in 2023, the company has acquired the WinGD brand and boast a domestic market share of 71%* in 2024. As a leading domestic manufacturer, MITSUI E&S has introduced dual-fuel engines compatible with methanol and LNG to the market since 2015, and is also working on compatibility with ammonia and hydrogen, which are expected to be next-generation fuels.

PRODUCTS & SERVICES
Engine Peripheral Systems
By supplying zero-emission fuel supply equipment such as tanks and pumps together with engines as a set, we can provide greater customer benefits. To achieve this, we are actively developing peripheral systems and our goal is to become a 'total marine propulsion system supplier', providing the entire propulsion system including the main engine and peripheral systems.
PRODUCTS & SERVICES
DX Service
As part of "ship digitalization transformation (DX)," we are developing and providing IoT services that monitor engine conditions through sensor data. Understanding current engine conditions will lead to lifecycle cost reductions through planned maintenance and safe navigation by detecting any early signs of abnormalities.
PRODUCTS & SERVICES
After-sales Service
We support our customers so that engines and peripheral systems operate in optimal condition over the long term after the ship goes into service. In addition to technical services and parts supply, we also provide specialized maintenance management training and fuel efficiency improvement products for ships in service.
