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.

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

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 35 to 95 cm bore sizes have a total power range from 4,350 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.

ME-GI Two-Stroke Engine Continues March towards 1,000 Orders

Newbuildings confirm dual-fuel engine’s status as market leader

MAN Energy Solutions reports that its MAN B&W dual-fuel ME-GI engine has had a strong start to the year, confirming its status as the default, dual-fuel methane-fuelled engine. Since its market debut in 2014, the ME-GI has been broadly accepted by all marine segments and is expected to shortly round 1,000 engine orders.

MAN Energy Solutions reports that the strongest interest in the engine has come from the container segment with more than 400 engines ordered, followed by gas and liquid tanker vessels (225+), and car & truck carriers (175+).

International shipping line, Mediterranean Shipping Company S.A. (MSC), has played a prominent role in the adoption of the ME-GI and has added more than 125 of the two-stroke engines to its fleet, making it the largest ME-GI owner. The same company has also demonstrated its strong support for MAN Energy Solutions’ Pump Vaporizer Unit (PVU) and is also the customer with most contracts signed for this product.

Giuseppe Gargiulo – Head of Newbuildings, MSC – said: “The two-stroke ME-GI provides us with the lowest methane slip, best gas consumption, and an attractive pilot-oil consumption as we navigate towards net zero. We have around 150 dual-fuel vessels on our order book currently to make our fleet the most modern and efficient in the industry. It is thanks to world-class suppliers like MAN Energy Solutions that we have been able to achieve this important energy transition milestone for our fleet.” 

Bjarne Foldager – Head of Two-Stroke Business – MAN Energy Solutions, said: “The ME-GI engine stands out by virtue of its having the lowest methane slip of any engine in the market. We have recently experienced a huge uptake in orders of ME-GI engines and believe the reason is that LNG is a brilliant transition fuel with which to reach the long-term goal of decarbonising shipping. The LNG supply chain is the most mature and a supply of fossil LNG is available in most key ports around the world. As increased quantities of bio- and synthetic LNG become available at commercially viable prices, the ME-GI engine will allow shipowners to progress even further on the decarbonisation pathway and reach net-zero greenhouse-gas emissions. This, coupled with the ME-GI’s market-leading efficiency and technological maturity that have won references in all available market segments, is an achievement we feel justifiably proud of. Every order represents an owner’s trust, which is truly humbling.”

Christian Ludwig – Head of Two-Stroke Sales and Promotion – MAN Energy Solutions, said: “With an installed engine-output power base of more than 25 million kW, the ME-GI plays a leading role in terms of numbers, power and running hours against any dual-fuel, two-stroke engine in the market. Since its introduction – and including its upgrade to the ME-GI Mk II – these engines have formed the backbone of our dual-fuel engine portfolio. Available from 35-bore to 95-bore, these market-leading engines cover most propulsion needs. Even passenger ferries have taken to these engine – and our PVU for that matter – due to their many merits.”
