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 600,000 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.
