The present invention relates to a liquefied gas storage tank and a marine structure including the same. The liquefied gas storage tank comprises a buffering partition installed within the liquefied gas storage tank and disposed to be adjacent to a side wall of the liquefied gas storage tank; a one-directional watertight door provided in a portion of the buffering partition and opened and closed in a direction toward the side wall; a vertical support supporting and fixing the buffering partition; and a damping unit formed by the side wall and the buffering partition and reducing a sloshing impulsive load applied to the side wall when a storage space of the liquefied gas storage tank is filled with the liquefied gas supplied through the one-directional watertight door. In the liquefied gas storage tank and the marine structure having the same according to the present invention, since a sloshing impulsive load reducing device is installed to be adjacent to the side wall of the liquefied gas storage tank, a sloshing impulsive load applied to the side wall of the liquefied gas storage tank due to a sloshing phenomenon can be reduced, securing stability of the liquefied gas storage tank and realizing an extra-large liquefied gas storage tank. Also, since the sloshing impulsive load reducing device can be partially installed in the liquefied gas storage tank, there is no need to deform a structure of the liquefied gas storage tank.

    본 발명은 액화가스 저장탱크 및 이를 구비한 해양구조물에 관한 것으로서, 본 발명의 액화가스 저장탱크는, 액화가스 저장탱크의 내부에 설치되며, 상기 액화가스 저장탱크의 측벽에 근접 배치되는 완충격벽; 상기 완충격벽의 일부분에 구비되며, 상기 측벽 방향으로 개폐되는 일방향 수밀문; 상기 완충격벽을 지지 고정하는 수직 지지부; 및 상기 측벽과 상기 완충격벽에 의해 형성되며, 상기 액화가스 저장탱크의 저장공간에서 상기 일방향 수밀문을 통해 공급되는 액화가스가 채워져 상기 측벽에 가해지는 슬로싱 충격하중을 저감시키는 댐핑부를 포함하는 것을 특징으로 한다. 본 발명에 따른 액화가스 저장탱크 및 이를 구비한 해양구조물은, 액화가스 저장탱크의 측벽에 근접하도록 슬로싱 충격하중 저감장치를 설치함으로써, 슬로싱 현상으로 인하여 액화가스 저장탱크의 측벽에 가해지는 슬로싱 충격하중을 저감시킬 수 있어, 액화가스 저장탱크의 안정성을 확보할 수 있고, 액화가스 저장탱크의 초대형화를 실현할 수 있다. 또한, 본 발명에 따른 액화가스 저장탱크 및 이를 구비한 해양구조물은, 슬로싱 충격하중 저감장치를 액화가스 저장탱크에 부분적으로 설치가 가능함으로써, 액화가스 저장탱크의 구조를 변형시킬 필요가 없다.
