High power combined with high efficiency:
Discover our portfolio of proven MAN B&W two-stroke engines
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.

Hapag-Lloyd Exercises Option for Further ME-GI Engines
Daewoo Shipbuilding & Marine Engineering (DSME) has ordered 6 × MAN B&W 11G95ME-GI Mk10.5 main engines in connection with the building of 6 × ultra-large, 23,500+-teu container vessels for Hapag-Lloyd, one of the world’s leading liner-shipping companies. The new order stems from an option associated with an identical order for six such vessels originally announced in December 2020, where Hapag-Lloyd also chose the environmentally-friendly ME-GI engine.
The engines will be built in Korea and offer the option of operating on LNG or conventional fuel, meeting Tier III emission standards through SCR (Selective Catalytic Reduction). The first engine delivery is scheduled for May 2022. DSME is set to deliver the first six boxships between April – December 2023, with the six ships covered by the new option scheduled for delivery by end-2024.
Wayne Jones OBE, Chief Sales Officer and Member of the Executive Board of MAN Energy Solutions, said: “The exercising of this option is a great show of confidence in the ME-GI engine and showcases MAN Energy Solutions’ continued leadership in the dual-fuel segment. As public criticism of emissions within the shipping segment increases exponentially, the ME-GI – with its extremely low methane-slip – is an increasingly attractive propulsion-solution, and particularly so for vessels such as large container ships.”
Bjarne Foldager, Senior Vice President and Head of Two-Stroke Business at MAN Energy Solutions, said: “The ME-GI is the world’s most efficient LNG engine, backed up by more than 1.7 million running hours on LNG alone, as well as our unique partnership approach and follow-up commitment for vessels in service. Furthermore, it has low CO2 and greenhouse-gas emissions, and a modular platform that facilitates conversion to other alternative fuels such as ammonia – should the need arise – which makes the engine truly future-proof.”
About Hapag-Lloyd
