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: 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-GA-opti’ Optimises Combustion Onboard LNG Carrier Newbuilding
The first LNG carrier in a series currently under construction by Samsung Heavy Industries (SHI) in Korea has completed gas trials. Originally ordered in Q2 2021 and scheduled for delivery in July 2023, the ship is powered by MAN B&W ME-GA dual-fuel engines capable of running on fuel oil and LNG, and comes with Exhaust Gas Recirculation (EGR) for emission reduction. MAN Energy Solutions furthermore reports that – as a first – the engine-control system sports a new control feature called ‘ME-GA opti’ for optimal engine operation through individual cylinder control.
Bjarne Foldager, Senior Vice President and Head of Two-Stroke Business, MAN Energy Solutions, said: “MAN Energy Solutions has always played a leading role in developing groundbreaking technologies that add value to our customers’ operations. Thus we have made EGR standard for the ME-GA, thereby reducing methane slip compared to first-generation Otto-cycle engines without EGR, which simultaneously improves fuel efficiency in both gas and fuel-oil operation. ME-GA-opti continues this trend and will further boost the ME-GA’s reputation.”
Thomas S. Hansen, Head of Promotion and Customer Support, MAN Energy Solutions, said: “ME-GA-opti is the latest and most advanced control feature for the ME-GA engine and significantly improves its operation. It comprises an advanced and intelligent network of control algorithms that have been developed to optimise the combustion process on an individual-cylinder basis, and which ensure optimal operating conditions. I’m certain it will be received well by the market.”
ME-GA-opti’s intelligent functionality benefits engine performance in several ways, including by:
- ensuring optimised conditions for the combustion process by reducing the influences of ambient temperature, pressure and humidity that can influence Otto-cycle engines;
- enabling maximum and stable gas potential for the engine;
- reducing fuel-ratio control activation – MEGA-opti is able to adapt the engine’s running conditions as the combustion moves towards the pre-ignition limit.
About ME-GA
The MAN B&W ME-GA engine delivers a low CAPEX solution aimed at certain contemporary LNG carrier designs,
Based on the well-proven MAN B&W dual-fuel design with minimal installation requirements, the MAN B&W ME-GA uses an efficient ignition concept and unique gas-admission system that delivers safe and reliable operation.
The ME-GA furthermore features minimal operational costs, simple supply and purging concepts, and low maintenance costs for its fuel-gas supply system. It joins the well-established ME-GI Diesel-cycle engine in MAN Energy Solutions’ two-stroke-engine portfolio, which now offers both low- and high-pressure, dual-fuel solutions for operation on LNG.
