Title: LNG FUEL-RECEIVING SYSTEM FOR USE IN SHIP, SHIP EQUIPPED WITH SAME, AND LNG FUEL-RECEIVING METHOD FOR USE IN SHIP
Abstract:
Provided is an LNG fuel-receiving system for use in a ship and capable of transporting LNG from an external LNG supply source without wastefully consuming fuel by BOG incineration, unnecessary ship travel, and the like, even in ships not equipped with a boiler. An LNG fuel-receiving system for use in a ship and equipped with an LNG transport pipe capable of transporting LNG to a fuel tank from a connecting part that is connected to an external LNG supply source, a boost pump positioned on the LNG transport pipe, and a spray nozzle for spraying LNG from the LNG transport pipe into a gas-phase section of the fuel tank, wherein: the pressure inside the fuel tank is reduced so as to be lower than the pressure of the external LNG supply source by spraying the LNG into the gas-phase section of the fuel tank using the boost pump, and when the pressure inside the fuel tank becomes lower than the pressure of the external LNG supply source, a switch from LNG spraying into the gas-phase section of the fuel tank to LNG supply to the fuel tank occurs as a result of the pressure difference between the pressure of the external LNG supply source and the pressure inside the fuel tank.
