<p>Disclosed are a hybrid fuel supply system for a ship engine and a method thereof. According to the present invention, the hybrid fuel supply system for a ship engine comprises: a pressure-resistant tank storing liquefied natural gas; a first flow path for supplying liquefied natural gas stored in the pressure-resistant tank to a ship engine by pumping liquefied natural gas or vaporizing liquefied natural gas without pumping; and a second flow path supplying BOG (Boil Off Gas) generated from liquefied natural gas stored in the pressure-resistant tank to the ship engine. As design pressure of the pressure-resistant tank is higher than operating pressure of the ship engine, either liquefied natural gas or BOG is supplied to the ship engine by internal pressure of the pressure-resistant tank without pumping if the internal pressure of the pressure-resistant tank is higher than the operating pressure of the ship engine.</p> |
