High Pressure LNG Fuel  Systems in Marine Service

LNG as a marine fuel has shown great potential as a clean, safe, reliable, and cost effective alternative to diesel fuel in an ever changing global environment. Perhaps the most significant of these changes has been the International Maritime Organization implementation of MARPOL Annex VI. MARPOL Annex VI was initially implemented in 2005 to lower global SOX and NOX emissions, and then revised later that year, with the revision being implemented in 2010. This revision called for further increases in global emission regulations, as well as for the development of emission control areas (ECA) in which emissions would be further regulated. To comply with these regulations, a large focus was placed on the quality and compositions of fuels used in maritime service, resulting in a plan that would reduce the current diesel fuel sulfur limits from 3.50% to just 0.50%, to be effective as of January 1, 2020. As often occurs when necessity stokes the flames of ingenuity and invention, the notion of this potentially more costly and less available lower sulfur diesel fuel inspired many to look for prospective alternatives. Eventually this resulted in a push to research and implement the use of liquefied light hydrocarbons – LNG being the most common – as marine fuels. ACD has experience with both low pressure (approximately 8 bar) port injected engines, and high pressure (approximately 300 bar) direct injected engines, the more intricate of which is the high pressure variety.
