PURPOSE: A re-liquefying apparatus of a liquefied natural gas carrier is provided to control the temperature of cooling water for cooling a refrigerant for liquefying gas, and to enhance the cooling efficiency. CONSTITUTION: A re-liquefying apparatus of a liquefied natural gas carrier comprises the following: a cooling water line(310) supplying a circulating passage to cooling water cooling a refrigerant for liquefying gas; a cooling water cooler(320) installed on the cooling water line; a bypass line(330) bypassing the cooling water cooler; a bypass valve(340) opening and closing the flow of the cooling water; a cooling water temperature sensor(350); a setting unit setting the temperature of the cooling water; and a temperature controlling unit(370) controlling the bypass valve to reach the set temperature. |
