FIELD: engines and pumps.
SUBSTANCE: invention can be used in fuel supply systems of vessel internal combustion engines (ICE). Disclosed is a hybrid fuel supply system for engine of vessel, comprising: compression device (200) configured to compress boil-off gas generated from liquefied natural gas stored in an cargo tank; high pressure pump (300) configured to compress liquefied natural gas supplied from the cargo tank; vaporizer (310) configured to vaporize the liquefied natural gas compressed by the high pressure pump, and an engine (100) to which the boil-off gas compressed through compression device (200) or liquefied natural gas, compressed by high pressure pump (300) and vaporized in the vaporizer (310), are supplied as fuel. Engine of the vessel uses high pressure gas compressed at 150 to 400 bar.
EFFECT: disclosed is a hybrid fuel supply system for engine of vessel.
