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 operational 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
