PURPOSE: A LNG fuel supply system for a ship engine is provided to rapidly cope with the required output of the ship engine by controlling the evaporation amount of LNG. CONSTITUTION: A LNG fuel supply system for a ship engine(300) comprises a LNG fuel tank(100), a working fluid storage tank(200), a fuel supply line(L4), a coolant circulation line(L5), a working fluid circulation line(L6), and a heat exchanger(400). The ship engine uses natural gas vaporized by the working fluid storage tank as fuel. The fuel supply line connects the working fluid storage tank and the ship engine, and supplies the vaporized natural gas to the ship engine. The coolant circulation line is connected to the ship engine, and coolants are circulated. The working fluid circulation line is connected to the working fluid storage tank, and the working fluid is circulated. The heat exchanger is connected to the coolant circulation line and working fluid circulation line so that the coolants are heat exchanged with the working fluid.
