Disclosed are a system for controlling the temperature of a storage tank in a ship and a method thereof. The system comprises: a plurality of storage tanks provided in the ship to store liquefied gas; a vapor main line for transferring the boil-off gas, generated from the storage tanks, to gas consumption points in the ship; a re-liquefaction unit for receiving the boil-off gas from the vapor main line and re-liquefying the same; a return line for recovering the liquefied gas, re-liquefied by the re-liquefying unit, to the storage tanks; and condensate spray nozzles provided inside gas domes above the storage tanks. Therefore, the condensate spray nozzles can receive the liquefied gas, re-liquefied by the re-liquefaction unit, from the return line and can spray the same into the storage tanks, thereby lowering the temperature of the boil-off gas discharged from the storage tanks.

    선박의 저장탱크 온도 조절 시스템 및 방법이 개시된다. 본 발명의 선박의 저장탱크 온도 조절 시스템은, 선박에 복수로 마련되어 액화가스가 저장되는 저장탱크; 상기 저장탱크로부터 발생하는 증발가스를 선내 가스소비처로 이송하는 베이퍼메인라인; 상기 베이퍼메인라인으로부터 증발가스를 공급받아 재액화하는 재액화부; 상기 재액화부에서 재액화된 액화가스를 상기 저장탱크로 회수하는 리턴라인; 및 상기 저장탱크 상부의 가스 돔 내측에 마련되는 컨덴세이트 스프레이노즐:을 포함하고, 상기 컨덴세이트 스프레이노즐에서는 상기 재액화부에서 재액화된 액화가스를 리턴라인으로부터 공급받아 상기 저장탱크에 분사하여 상기 저장탱크로부터 배출되는 증발가스 온도를 낮출 수 있는 것을 특징으로 한다.
