MAN B&W ME-GI prepares your fleet for future regulations
The MAN B&W ME-GI two-stroke dual-fuel engine provides a future-proof solution for LNG/methane-powered vessels thanks to its negligible methane slip and high fuel efficiency.
Based on one of the industry’s most trusted platforms, the MAN B&W ME-GI uses a high-pressure fuel supply system and is suitable for many types of vessels. The engine achieves exceptionally low methane slip emissions and provides a large degree of flexibility for meeting emissions regulations, now and in the future. We have also refined and simplified the design, upgrading key components, and improving reliability.
The world’s most efficient engine for methane as a fuel
Perfect for new builds or retrofits, the MAN B&W ME-GI minimizes operating costs by delivering high industry-leading thermal efficiencies no matter which fuel is used. This is a huge advantage, especially for container vessels in a market with fluctuating fuel prices. The ME-GI can also be fueled with bio-methane as well as synthetic natural gas, providing a clear route towards greenhouse gas reductions.
Next-generation performance and efficiency
Key benefits
- Proven two-stroke MAN B&W engine technology
- Minimal environmental impact (low emissions thanks to negligible methane slip and reduced CO2 emissions)
- No need to compensate with liquid oil fuels to accommodate low methane numbers or high ambient temperatures
- Flexible operation using fuel oil or LNG
- Knocking is not an issue
- Supports waste heat recovery (WHR)
- Easy retrofit compared to Otto cycle engines
Low OPEX
The ME-GI is built for low OPEX, delivering the same industry-leading thermal efficiency no matter which fuel is used. This is a huge advantage in a fluctuating fuel market where LNG bunkering will become the norm. The auxiliary equipment costs have been reduced and the engine’s installation is simplified. Furthermore, key components have been updated to improve performance and deliver a more environmentally friendly solution.
Component upgrades
The new MAN B&W ME-GI incorporates a range of key component upgrades that improve reliability, maximize efficiency and lower OPEX, helping you to stay competitive in a challenging market.
- Lowest gas consumption of any marine two-stroke engine
- Simplified piping system provides a more compact solution with fewer components, and therefore lower maintenance costs
- New gas block with an improved window valve enables cut-out of an individual cylinder operating on gas, while allowing continued operation on fuel oil
- Updated pilot oil injection system enables the pilot oil energy fraction be lowered to just 1.5% for certain bore sizes
- Optional compact pump vaporizer unit features embedded redundancy (3 x 50%) and integration with the ME-GI engine control system

ME-GI Adds Container Reference
Samsung Heavy Industries (SHI) has confirmed an order for 10 × 8G95ME-GI10.5 engines in connection with the building of 10 × 15,000-teu containerships for Seaspan Corporation. The vessels are scheduled for delivery in the first half of 2023, and will immediately after begin 12-year charters for ZIM Lines – the international shipping group – serving the US East Coast trade.
Thomas S. Hansen, Head of Promotion and Customer Support, Two-Stroke Business, MAN Energy Solutions, said: “This is just the latest order the well-proven ME-GI concept has won in recent months. Its service experience, low methane slip, high efficiency, and fuel flexibility – whether running on fuel-oil or LNG – remain unparalleled in a market whose momentum towards a zero-carbon future is growing rapidly.”
The ME-GI engines will come with a newly introduced PVU (Pump Vaporizer Unit), which ensures an optimal integration between the engine and LNG-supply system.
MAN Energy Solutions announced in January 2021 that its low-speed, dual-fuel references in their entirety had exceeded 360 units, with the ME-GI recording over 1.5 million operating hours on LNG alone. Since then, among other references, 10 × MAN B&W 7G80ME-GI Mk9.5 dual-fuel engines were ordered in early March 2021 for a series of 10 × 300,000-dwt VLCCs, a début for the engine is this particular segment.
The ME-GI engine – the new 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 – container vessels, bulk carriers, tankers, LNG carriers and car carriers. The ME-GI engine provides ship-owners and operators with a peerless solution within environmentally friendly and high-efficiency, two-stroke technology, without the greenhouse emissions such as methane slip that are characteristic of competing engines.
With the ME-GI engine, two-stroke development has taken a step further by combining the unique properties of multi-fuel combustion and the well-known reliability of MAN Energy Solutions ME-engine. The Diesel principle not only provides the ME-GI engine with high operational stability and efficiency, but also ensures 100% stable and 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 operation and diesel operation The ME-GI engine is the most environmentally-friendly technology available within the 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 more sustainable fuels such as methanol and liquefied petroleum gas (LPG).
The Maritime Energy Transition
MAN Energy Solutions believes that it is time for what it terms a ‘Maritime Energy Transition’ to find clean, decarbonised solutions for seaborne trade and transportation. Essentially, it is the company’s call to action to reduce emissions and establish natural gases as the fuels of choice in global shipping. It strongly promotes a global ‘turn to gas’, driven by the IMO, and a common approach by the shipping industry and politics to invest in infrastructure development and retrofits.
