MAN B&W two-stroke engines for LPG carriers

LPG is the fuel of the future – environmentally friendly and smart without sacrificing performance or efficiency. For example, LPG contains close to zero sulfur and  meets the requirements for Sulfur Emission Control Areas.

Efficient, clean, and flexible: MAN B&W dual fuel engines

By switching to LPG, your carrier will achieve full compliance with all future SOx regulations as well as gaining a competitive advantage of up to 18% fewer CO2 emissions without loss of performance or efficiency.

Switching to LPG also has financial benefits, as it is much more affordable than MGO. Another benefit is the storage of the fuel – it is by far more reasonable than competing products like LNG.


In 2018, we were the first company to introduce a new and innovative dual fuel engine: The MAN B&W ME-LGIP.

The MAN B&W ME-LGIP is the world’s first and only dual fuel engine with liquid gas injection that allows switching between conventional HFO, MGO, and LPG fuels without any loss of performance or efficiency. This innovative technology offers the flexible option of using conventional fuels supplementally and thus benefiting from optimum market prices.

LPG Carriers to keep your business running

Traditionally operating with conventional fuel-burning engines, LPG carriers need intelligent fuel-saving options to run efficiently and cost-effectively. With a viable, convenient, and comparatively cheap fuel already onboard, it makes sense to save time for bunkering by using a fraction of the cargo to power the vessel, which brings important environmental side benefits. In this respect, the ability of the ME-LGIP engine to run on LPG, a sulphur-free fuel, offers great potential for compliant ship operation within SECA zones. The modular design principle of our ME-C engines allows simple conversions to LGIP, which is especially beneficial to LPG Carriers already in service with conventional fuel engines. 

As an additional feature, the LPG engine has great potential for being a solution to handle the volatile organic compound (VOC) issue in shuttle tankers and other crude oil carriers. This is because the engine features innovative options for burning the liquid volatile organic compound (LVOC). The engine can burn any mixture of propane and butane, and furthermore, the mixture can contain significant amounts of ethane. All heavier hydrocarbons normally contained in the LVOC can be used as well.
