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.
