A cool-down system and method for an LNG storage tank are disclosed. The cool-down system for an LNG storage tank, which is prepared in an LNG carrier, comprises: a fuel tank which stores LNG supplied to propulsion fuel of the LNG carrier therein; an LNG storage tank which is prepared in a cargo hold of the LNG carrier; and a spray nozzle which is prepared on the top of the LNG storage tank and sprays the LNG to the inside of the LNG storage tank. Therefore, the present invention cools the LNG storage tank when the LNG carrier sails in ballast by supplying the LNG from the fuel tank to the spray nozzle.

    LNG 저장탱크의 쿨-다운 시스템 및 방법이 개시된다. 본 발명의 LNG 저장탱크의 쿨-다운 시스템은, LNG 운반선에 마련되는 LNG 저장탱크의 쿨-다운 시스템에 있어서, 상기 LNG 운반선의 추진 연료로 공급되는 LNG가 저장되는 연료 탱크; 상기 LNG 운반선의 화물창에 마련되는 LNG 저장탱크; 및 상기 LNG 저장탱크의 상부에 마련되며 LNG를 상기 LNG 저장탱크 내부에 분사하는 스프레이 노즐을 포함하여, 상기 LNG 운반선의 밸러스트 운항시에 상기 연료 탱크로부터 LNG를 상기 스프레이 노즐로 공급하여 상기 LNG 저장탱크를 냉각시킬 수 있는 것을 특징으로 한다.
