Introducing the new MAN B& W ME-LGIP: the world's first dual-fuel LPG marine engine

In face of new regulations and fluctuating fuel prices, the innovative new MAN B&W ME-LGIP de-risks your investment and lets you take back control.

Ideal for new ship orders or as retrofit solution on any vessel type, the MAN B&W ME-LGIP builds on MAN's leadership in two-stroke, dual-fuel technology to set new standards for fuel-efficiency. flexibiliy and operational simplicity.

With LGP, you stay compliant with upcoming emission regulations.
Maximize fuel efficiency by switching between HFO, MGO or LPG with no performance loss.

Dual-fuel means operational security

MAN’s dual-fuel engine technology gives you unprecedented financial and operational security. 

By switching to LPG, you achieve full compliance with all upcoming SOx regulations and get a competitive edge of 13% less CO2 emissions, with no loss of performance or efficiency. You also retain the flexibility to use conventional fuels to take advantage of optimal market prices. 



LPG is a zero-sulphur fuel with relative lower carbon content, which helps you achieve full compliance with upcoming IMO 2020 SOx regulations as well as the 2050 IMO GHG targets.

LPG also gives credit towards your IMO EEDI compliance requirements. 


LPG gives you greater financial security; it is traditionally a cheaper fuel than MGO yet delivers the same performance and efficiency. 

Using our dual-fuel engine technology, you can also take advantage of fluctuating fuel prices in the future. Importantly, the ability to use LPG cargo as a supplement fuel source provides significant cost savings for LPGC owners or charterers, including reduced time and fees for fuel bunkering.


Switching to LPG helps to support operational continuity. As a widespread energy source, availability is high and LPG is easier to store and handle, compared with cryogenic gaseous fuels. 

Lastly, by ensuring your fleet is compliant in all international waters, you eliminate any risk of disruptions (and potential port fines) to your global shipping schedule.
