Liq·uid Gas In·jec·tion Pro·pane [ ˈlɪkwɪd gæs ɪnˈʤekʃən ˈprəʊpeɪn ], first dual-fuel two-stroke engine to power VLGCs (Very Large Gas Carriers) with conventional diesel oil and LPG (liquefied petroleum gas).

The International Maritime Organization, IMO has adopted that the sulfur content of marine fuels must be reduced from the current 3.5 percent to 0.5 percent globally by 1 January 2020. This decision presents shipowners all over the world with enormous challenges, which is why the urgent search is on to find alternatives to the fuels most commonly used until now, such as heavy fuel oil and marine diesel oil. The industry has high hopes of LPG as an option for powering its vessels, and MAN Energy Solutions has developed a dual-fuel two-stroke engine that can run on conventional diesel oil and on LPG. The new MAN B&W G60ME-C-LGIP engine is based on the concept employed in ME-GI and LGI engines, which MAN has been developing into a modern design since 2011. As LPG does not contain sulfur, the ME-LGIP engines make an important contribution to complying with the IMO sulfur limits. Compared with marine diesel oil, the engines emit around 13 percent less CO₂ and some 90 percent less particulates with the same performance.
