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.

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: 72 – 100 rpm
  • Output: 8,600 – 21,440 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: 56 – 125 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: 72 –103 rpm
  • Output: 8,600 – 22,720 kW at L1

World’s Most Powerful Methanol Engine Announced

With ‘latest, remarkable milestone’, MAN Energy Solutions continues decarbonisation push

MAN Energy Solutions has announced that it will deliver the world's most powerful two-stroke methanol engine in June 2025. The engine, an MAN B&W 12G95ME-C10.5-LGIM (-Liquid Gas Injection Methanol) type rated at 82,440 kW @ 80rpm, is currently being built by Chinese licensee, CSSC-MES Diesel Co., Ltd. (CMD).

The engine is the first of 12 bound for a series of 12 × 24,000 teu container vessels currently under construction: seven at Nantong COSCO KHI Ship Engineering Co., Ltd. (NACKS) for shipowner, Orient Overseas Container Line Ltd. (OOCL); and five at Dalian COSCO KHI Ship Engineering Co., Ltd. (DACKS) for shipowner, COSCO Shipping Lines Co., Ltd. Each engine will also feature MAN Energy Solutions’ proprietary EGRTC (Exhaust Gas Recirculation Turbocharger Cut-­­­­­­out) emissions system, the largest two-string EGR system on a two-stroke engine to date.

Bjarne Foldager – Head of Two-Stroke Business – MAN Energy Solutions, said: “At MAN Energy Solutions, our vision of 'Moving Big Things to Zero' motivates everything we do in developing the engine technology to operate on those fuels vying for prominence in the future market. This latest, remarkable milestone – the world’s most powerful methanol engine – is just the latest fulfilment of that. By harnessing the potential of methanol, we are bringing the maritime industry closer to zero-emission solutions and we fully expect methanol to figure prominently as a future-fuel across all segments. Our thanks go to CMD, OOCL and COSCO Shipping, valued partners with whom we continue to share so many highlights.”

Christian Ludwig – Head of Two-Stroke Sales and Promotion – MAN Energy Solutions, said: “As we move towards a multi-fuel future, interest in methanol has grown steadily. To date, between newbuild engines and retrofits, we have won over 230 ME-LGIM references that have accumulated over 600,000 hours running on methanol alone. With ME-LGIM technology reaching 10 years in the market, it represents mature, proven technology and reflects MAN Energy Solutions’ ability to develop attractive technology to enable shipping’s carbon transition. Furthermore, while 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 – adding to the benefits the ME-LGIM brings to the table.”

About the MAN B&W ME-LGIM engine

MAN Energy Solutions developed the ME-LGIM dual-fuel engine for operation on methanol, as well as conventional fuel. The engine is based on the company’s proven ME-series, with its approximately 8,500 engines in service, and works according to the Diesel principle. When operating on green methanol, the engine offers carbon-neutral propulsion for large merchant-marine vessels.

Methanol carriers have already operated at sea for many years using the engine, and, as such, the ME-LGIM has a proven track record offering great reliability and high fuel-efficiency.
