According to the statement, the compressors will be delivered to Hyundai Mipo Dockyard as part of the fuel gas supply system built by Wärtsilä Oil & Gas Solutions, and will supply the LNG carrier’s WinGD X-DF 2-stroke, dual-fuel engine with LNG boil-off gas (BOG) as fuel.
Burckhardt claims that the X-DF engine – a two-stroke engine from Winterthur Gas & Diesel – allows both natural gas and marine diesel to be used as fuel for ship propulsion systems. Ship operators are able to switch between both fuel types – maritime diesel and BOG that inevitably evaporates from LNG storage tanks – during operation.
