Enabling a scalable energy transition 

The MAN B&W ME-LGIM is a two-stroke, dual-fuel engine that can run on methanol as well as conventional fuels.

The engine provides an efficient, proven, and reliable solution, and plays an important role in the decarbonization of the maritime industry. Simple handling, storage, and bunkering of methanol, combined with relatively simple auxiliary systems and the potential to be carbon-neutral, makes it an attractive option for meeting decarbonization targets.

The first MAN B&W ME-LGIM engines came into service in 2016
running hours accumulated on methanol alone


Proven two-stroke methanol engine design

Available for newbuilds or for upgrading existing conventional fuel vessels, the engine represents a proven and refined engine design based on more than 120,000 running hours on methanol alone.

When fuelled by methanol, the MAN B&W ME-LGIM engine significantly reduces greenhouse gas emissions, particles, and SOx emissions. Methanol produced from renewable sources can provide carbon-neutral propulsion.


Engines and applications

LGIM EnginesThanks to an extensive existing ME-LGIM engine portfolio, our methanol solution caters to a wide range of vessel applications, including container vessels of all sizes, product tankers, VLCCs, numerous bulk carrier sizes, RoRos, and PCTCs.

Scalable energy transition

LGIM ShippingThe major appeal of methanol as an alternative fuel is that it can be stored as a liquid at ambient temperatures and pressures. While its production as a green fuel is still limited, its handling costs are low, reducing the complexity of storage and bunkering infrastructure at ports.

Recent methanol engine orders reflect a carbon-neutral approach from ship owners, since they will be fuelled by carbon-neutral green methanol whenever this is available at scale.

The engine works with the same high efficiency known from our existing conventional fuel engines. Switching between methanol and fuel oil is seamless and thereby supports reliable and continuous operation of the engine.

Low-Speed, Dual-Fuel Portfolio Reaches Millennial Milestone

Individual ME-GI orders surpass 500 mark

MAN Energy Solutions has announced that its portfolio of two-stroke, dual-fuel engines has passed more than 1,000 units on order or in service. The engines can run on a variety of alternative fuels, including LNG, methanol, ethane and LPG. The company notes that the new mark also comprises part of an even larger milestone of more than 2,500 Tier-III compliant engine orders.

Bjarne Foldager, Senior Vice President and Head of Low-Speed, MAN Energy Solutions, said: “This is yet another, significant milestone for our dual-fuel portfolio that provides the green solutions desired by the marine market. Our low-speed engines offer multiple paths to decarbonisation and we see the increasing adoption of dual-fuel technology as an irreversible trend.”

MAN Energy Solutions’ dual-fuel journey began in 2011 with a full-scale demonstration of an ME-GI (-Gas Injection) engine at its Research Centre Copenhagen, followed by the first engine delivery in 2014. The ME-GI remains the most prominent dual-fuel engine with more than 500 orders. It is the world’s most efficient LNG-fuelled engine and has extremely low levels of methane slip, which make it the industry’s leading dual-fuel engine across vessel types such as container vessels, bulk carriers, tankers and car carriers.

The first engine tests of the ME-LGI (-Liquid Gas Injection) platform began in 2015, followed by the first sea-trial for the ME-LGIM (methanol) engine in 2016. Development of an ethane (ME-GIE) unit followed in 2016 with sea-trials already in 2017. Currently, more than 240 dual-fuel engines have entered service, while an MAN B&W ammonia-fuelled engine is due to be delivered to a shipyard by 2024.

Thomas S. Hansen, Head of Promotion and Customer Support, MAN Energy Solutions, said: “Of the thousand dual-fuel engines on order or in service, these include more than 214 ME-GA engines, testimony to the success of the second-generation Otto-cycle engine for LNG carriers that offer reduced methane-slip emissions. The first ME-GAs have already been delivered to shipyards and the first vessels will enter service in June 2023. In general, our future outlook on dual-fuel contracting per number of vessels expects that 50% of all vessels will be dual-fuel by 2026. Measured in engine power, more than 60% of all ordered engines are expected to be dual-fuel in 2026.”

Peter Quaade, Head of Dual-Fuel Engine Group – Two-Stroke Operations – MAN Energy Solutions, said: “The performance of newly developed engines demands heightened attention upon their market introduction to optimise performance and resolve any technical challenges. Over time, we have identified and resolved issues such that our dual-fuel portfolio is reliable, mature technology that has achieved exceptionally high running-times of more than 95% on alternative fuels. These dual-fuel engines’ seamless switching between fuels, elimination of fuel-slip, and use of the Diesel combustion principle ensures that they easily adapt to whatever fuels the industry may prefer in the future.”
