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-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.

Methane-Fuelled ME-GI Engines Continue to Lead Way with Lowest Methane Slip and Highest Fuel Efficiency
New Times Shipbuilding Co. Ltd. of Jiangsu province, China has ordered 12 × 8G95ME-GI (-Gas Injection) Mk10.5 main engines in connection with the construction of 12 × 18,000 teu container vessels for Eastern Pacific Shipping (EPS), the Singapore-based shipping company.
Bjarne Foldager – Country Manager, Denmark – MAN Energy Solutions, said: “This new, sizable order reflects the great momentum the ME-GI engine has experienced during the building boom that the Very Large Container Vessel segment is currently experiencing. EPS is an old acquaintance of MAN Energy Solutions with whom we have built an excellent relationship over the years. This is just the latest in a series of mutual, recent ME-GI projects and we thank them for placing their trust in us again.”
Thomas S. Hansen – Head of Two-Stroke Sales and Promotion – MAN Energy Solutions, said: “The ME-GI’s mature technology brings a number of advantages to the table, not least its guaranteed, extremely low levels of methane slip that make it the most future-proof methane engine on the market. It also has the highest fuel efficiency in its class, which explains why the G95ME-GI Mk10.5 has been specified for more than 60 Very Large Container Vessel newbuilds in just the past two months. The ME-GI is furthermore capable of operating on bio-methane and synthetic natural gas that render it net-zero and provide a viable decarbonisation pathway for shipowners.”
The ME-GI engine – the industrial standard
MAN Energy Solutions successful ME-GI (-Gas Injection) engine has set a new industrial standard for two-stroke propulsion engines aboard – among others – RoRo vessels, PCTCs, container vessels, bulk carriers, tankers and LNG carriers. The ME-GI engine provides ship owners, charterers and operators with a peerless solution within environmentally friendly and high-efficiency, two-stroke technology but without the prominent methane-slip emissions that are characteristic of competing engines.
The Diesel principle not only provides the ME-GI engine with high operational stability and efficiency, but also ensures 100% reliable operation during load changes on gas with just normal additions of pilot-oil amounts. Furthermore, the ME-GI operational principles features a seamless change-over between gas and diesel operation. The ME-GI engine is the most environmentally-friendly technology available within the LNG-fuelled, two-stroke engine segment.
MAN Energy Solutions has also developed an ME-LGI (-Liquid Gas Injection) dual-fuel engine that expands the company’s dual-fuel portfolio, enabling the use of sustainable fuels such as green methanol.
