The present invention relates to a liquefied gas storage tank and a marine structure including the same. The liquefied gas storage tank according to the present invention comprises: an evaporated gas absorption unit absorbing evaporated gas which is evaporated from liquefied gas in a storage space of the liquefied gas storage tank; an evaporated gas discharge unit discharging the evaporated gas toward the inside of the storage space to distribute sloshing energy; a flow direction metering device sensing the flow direction of the liquefied gas and outputting a flow direction signal; and an absorption and discharge control unit connected to the evaporated gas absorption unit and the evaporated gas discharge unit to detect the flow direction signal received from the flow direction metering device and to control whether the evaporated gas is absorbed or discharged. The liquefied gas storage tank and the marine structure having the same according to an embodiment of the present invention installs a sloshing load reducing device which can discharge the evaporated gas from the side wall and the ceiling of the liquefied gas storage tank to distribute the sloshing energy, thereby being capable of reducing a sloshing load applied to the side wall and the ceiling of the liquefied gas storage tank because of a sloshing phenomenon, so the stability of the liquefied gas storage tank may be ensured and the liquefied gas storage tank may be implemented to have an ultra-large size.

    본 발명은 액화가스 저장탱크 및 이를 구비한 해양구조물에 관한 것으로서, 본 발명의 액화가스 저장탱크는, 액화가스 저장탱크의 저장공간에서 액화가스로부터 기화된 기화가스를 흡입하는 기화가스 흡입부; 상기 기화가스를 상기 저장공간의 내부쪽으로 분출하여 슬로싱 에너지를 분산시키는 기화가스 분출부; 상기 액화가스의 유동 방향을 감지하고 유동방향 신호를 출력하는 유동방향 계측장치; 및 상기 기화가스 흡입부와 상기 기화가스 분출부와 연결되어 상기 유동방향 계측장치로부터 수신된 상기 유동방향 신호를 검출하여, 상기 기화가스의 흡입 및 분출 여부를 제어하는 흡입분출 제어부를 포함하는 것을 특징으로 한다. 본 발명의 실시예에 따른 액화가스 저장탱크 및 이를 구비한 해양구조물은, 액화가스 저장탱크의 측벽 및 천장으로부터 기화가스를 분출시켜 슬로싱 에너지를 분산시킬 수 있는 슬로싱 하중 저감장치를 설치함으로써, 슬로싱 현상으로 인하여 액화가스 저장탱크의 측벽 및 천장에 가해지는 슬로싱 하중을 저감시킬 수 있어, 액화가스 저장탱크의 안정성을 확보할 수 있고, 액화가스 저장탱크의 초대형화를 실현할 수 있다.
