MAN B&W ME-C
Our ME-C engines with
electronic controls serve up a host of advantages. You can look forward to
superior performance parameters, compactness, fully integrated electronic control
as well as the necessary fuel injection pressure and rate shaping at any load.
Plus the ME-C engine can be retrofitted for alternative fuels such as methanol,
LPG, LNG or ethane as well as ammonia from 2025.
- Engine speed: rpm to 56 – 167
- Output: 4,350 – 82,440 kW at L1
MAN B&W ME-GI
The ME-GI engine impresses with extremely low methane slip emissions and very high fuel efficiency. It is the most environmentally friendly LNG-fuelled engine on the market. By the optional use of fuel oil or LNG/bio-methane/SNG, it represents a highly efficient, flexible, propulsion-plant solution.
- Engine speed: rpm to 56 – 167
- Output: 4,350 – 82,440 kW at L1
MAN B&W ME-GIE
The technology of the ME-GIE is based on our successful ME-GI engine. This engine can be operated with ethane as well as fuel oil – which makes it the standard choice for ethane carriers. This engine offers very competitive fuel oil and gas consumption, plus operational stability and efficiency due to the diesel principle.
- Engine speed: 62 – 127 rpm
- Output: 8,600 – 29,120 kW at L1
MAN B&W ME-GA
The ME-GA engine is the latest addition to our dual fuel portfolio. Gas is admitted during the compression stroke, which allows for a lower supply pressure compared to other dual fuel engines. This is advantageous for LNG carriers with large amounts of boil-off gas. The ME-GA engine comes with our proven EGR design as standard for reduced methane slip emission, as well as improved fuel efficiency in both gas and fuel oil mode.
- Engine speed: rpm to 66 – 78
- Output: 14,150 – 16,980 kW at L1
MAN B&W ME-LGIM
Our ME-LGIM is a dual-fuel engine characterized by its high efficiency and capability of operating on methanol. With a proven record of more than 600.000 operating hours on methanol alone, the engine concept is proven and provides a high degree of reliability.
When fuelled by green methanol, our ME-LGIM engine can offer truly carbon-neutral propulsion, while reducing sulphur and particle matter emissions significantly at the same time.
- Engine speed: 58 – 117 rpm
- Output: 6,950 – 82,440 kW at L1
MAN B&W ME-LGIP
Our ME-LGIP is the only two-stroke dual-fuel engine on the market which can be fuelled with LPG. The low operational costs as well as the simple retrofit solution are particularly convincing.
- Engine speed: 62 –105 rpm
- Output: 8,600 – 22,720 kW at L1
Always an optimal choice
The MAN Energy Solutions two-stroke portfolio delivers the highest performance and efficiency across all engine types.
MAN B&W two-stroke engines from the 30 to 95 cm bore sizes have a total power range from 3,200 kW to 82,440 measured at L1. With a vast range of different fuel injection concepts from traditional fuel oils, to gaseous and liquid gasses, MAN ensures that you have your future fuel strategy covered.
All MAN B&W engines follow the same naming convention and seemingly random engine names actually carry a lot of useful information.

MITSUI Performs World-First Hydrogen Test
MAN Energy Solutions’ licensee, MITSUI E&S Co. Ltd., has announced that it has successfully tested a 50-bore MAN B&W two-stroke engine up to 100% load at its Tamano facility while running on hydrogen, a world-first for the maritime industry.
In collaboration with MAN Energy Solutions, MITSUI converted one of the four cylinders of an MAN B&W ME-GI (-Gas Injection) engine to hydrogen operation. The hydrogen was supplied from a hydrogen gas-supply system that MITSUI developed in 2023.
Stable operation was achieved at various loads and operating conditions, including successful hydrogen combustion up to 100% load. MITSUI also confirmed greenhouse-gas emission reductions of up to 95%, with the remaining fraction originating from the pilot-fuel employed during testing.
In its own press release, MITSUI stated: “This is the world's first successful hydrogen combustion test on a large, marine two-stroke engine. In achieving operation along with providing the hydrogen gas-supply system, we are now one step closer to developing a zero-emission ship that uses hydrogen as fuel.”
Gunnar Stiesch, Chief Technical Officer, MAN Energy Solutions, said: “This is a very interesting project and one of several activities related to hydrogen that MAN Energy Solutions is currently pursuing within both two- and four-stroke segments. My congratulations to MITSUI for achieving this world-first and pushing the envelope on decarbonisation.”
Brian Østergaard Sørensen, Vice President and Head of Research & Development, Two-Stroke Business at MAN Energy Solutions, said: “This exploratory work is illuminating and gives us much food for thought. MAN Energy Solutions continuously looks to support the decarbonisation journey within the maritime industry, and as often as possible with esteemed industry partners such as MITSUI.”
Bjarne Foldager – Country Manager, Denmark – MAN Energy Solutions, said: “We have worked closely with MITSUI on this research project and are very happy with the results achieved. This proves the advantages and the flexibility of two-stroke engine technology, and means that we are now also prepared for the future, not only for hydrogen derivatives but also for hydrogen as a fuel. MAN Energy Solutions closely follows the market to keep track of any significant developments and this test is a noteworthy progression.”
Thomas S. Hansen – Head of Sales and Promotion – MAN Energy Solutions, said: “MAN B&W-branded engines are flexible by nature and designed for an easy retrofit at a later stage to different fuel types. This is an encouraging milestone for hydrogen as a fuel. We will now take some time to evaluate the results and ensure that we are ready to take action if and when the market for hydrogen matures.”
