Marine engine fuel supply system and fuel supply method

摘要

When supplying LNG as fuel to a marine engine, fuel supply is smoothly performed while suppressing an abnormality in the apparatus. A submersible pump 100 provided in a ship LNG storage tank T for supplying LNG to a marine engine E; a high pressure pump 200 supplied with LNG from a submersible pump and compressing at a high pressure; and an LNG upstream of the high pressure pump. A return flow path RL that returns to the LNG storage tank is provided, and the flow rate of the LNG returned through the return flow path is controlled to control the temperature of the LNG at the front stage of the high-pressure pump.
