more than 100 ME-LGIP engines sold since 2018
up to 18% CO2 reduction when using LPG instead of fuel oil

Dual-fuel means operational security

MAN B&W dual-fuel engine technologies gives you unprecedented financial and operational security. 

By switching to LPG, you achieve full compliance with all SOx regulations and get a competitive edge of up to 18% less CO2 emissions, with no loss of performance or efficiency. You also retain the flexibility to use conventional fuels that will allow you to position your asset competitively regardless of market conditions. 



LPG is compliant with sulphur-emission control areas (SECA) regulations and emits lower CO2-emissions which also gives credit towards your IMO EEDI compliance requirements. 


LPG gives you greater financial security; it is traditionally a cheaper fuel than HFO 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 fuel source provides significant cost savings for LPG Carrier 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.
