HYBRID FUEL SUPPLY SYSTEM AND METHOD FOR A SHIP ENGINE

摘要

Disclosed is a hybrid fuel supply system for a ship engine having a storage tank storing a liquefied natural gas; and an engine using the liquefied natural gas as a fuel. The hybrid fuel supply system for the ship engine includes a compressor line compressing an evaporated gas generated in the storage tank by a compressor and supplying the gas to the engine as the fuel; a high pressure pump line compressing the liquefied natural gas housed in the storage tank by a pump and supplying the gas to the engine as the fuel; a reliquefying device reliquefying the evaporated gas compressed by the compressor and making the gas return to the storage tank; and a cold energy recovery unit recovering cold energy from the liquefied natural gas flowing along a second line after being compressed by the pump.
