Enabling a scalable energy transition
The MAN B&W ME-LGIM two-stroke dual-fuel engine can run on methanol as well as conventional fuels. Specifically designed to meet the needs of the maritime industry, it is a versatile and scalable solution that is suited to a wide range of vessel types. Simple handling, storage, and bunkering of methanol, combined with relatively simple auxiliary systems and the potential to be carbon-neutral, makes it an attractive option for meeting decarbonization targets.
Proven two-stroke methanol engine design
Available either for newbuilds or for upgrading existing conventional fuel vessels, this engine represents a proven, refined engine design based on over 450,000 running hours on methanol alone. Methanol produced from renewable sources is an attractive marine fuel option due to its low carbon intensity. An engine using green methanol can even provide carbon-neutral propulsion.
Key benefits
A new design for efficient methanol combustion
The ME-LGIM engine has inherited well-known components of our standard two-stroke diesel engine, like the ME-GI dual-fuel engine. Beneficial features of the standard MAN B&W two-stroke diesel engine have been retained. This illustration highlights methanol components and pipes that have been added to the cylinder top for methanol combustion.
The use of methanol as fuel type supports cost-effective vessel designs.

What our customers value
Listen to some of our low-speed customers describe the benefits of methanol-fueled engines as well as the support they get from MAN Energy Solutions throughout the entire product life cycle.

MAN Energy Solutions and A. P. Møller-Mærsk: Pushing carbon-neutral propulsion
Hyundai has placed an order for 6 MAN B&W G95ME-C10.5-LGIM dual-fuel main engines for 6 17,000 TEU container vessels for A.P. Moller – Maersk. Construction will take place in Korea and the engines will be able to run on green methanol, which will enable carbon-neutral propulsion for large merchant-marine vessels.
This illustrates that adoption of methanol-based engines is on the rise, not only because MAN B&W methanol engines are available, but also due to the proven track record of LGIM-powered vesselsCustomer: | A.P. Møller-Mærsk |
