본 발명은, 외부로부터 액화가스 저장탱크 내부로 액화가스를 유입시키는 외부관과 외부관의 내부에 설치되는 내부관을 포함하여 이중배관 구조로 마련되는 충전용 파이프; 및 충전용 파이프와는 별도의 유입구를 가지며 하단에 형성되는 배출관이 액화가스 저장탱크의 내측 상부 영역과 연통되어 유입구를 통해 유입된 액화가스를 액화가스 저장탱크 내부로 분사하는 내부관을 포함하고, (a) 충전용 파이프를 통해 내부관과 외부관 사이의 공간에 기화가스를 공급하여 예냉하는 단계; (b) 내부관을 통해 액화가스를 공급하여 액화가스 저장탱크 내부를 쿨다운시키는 단계를 포함하는, 이중배관 구조의 충전용 파이프를 포함하는 액화가스 저장탱크의 쿨다운 방법을 제공한다.

    The present invention discloses a method for cooling down a liquefied gas storage tank including a filling pipe provided in a double pipe structure, which comprises: a filling pipe provided in a double pipe structure by including an outer pipe for introducing liquefied gas from the outside into a liquefied gas storage tank and an inner pipe installed inside the outer pipe; and an inner pipe having an inlet separate from the filling pipe, and injecting the liquefied gas introduced through the inlet to the inside of the liquefied gas storage tank by having a discharge pipe formed at the bottom communicate with an inner upper area of the liquefied gas storage tank. The method for cooling down a liquefied gas storage tank including a filling pipe of a double pipe structure comprises steps of: (a) pre-cooling by supplying vaporized gas to the space between the inner pipe and the outer pipe through the filling pipe; and (b) supplying liquefied gas through the inner pipe to cool down the inside of the liquefied gas storage tank.
