The present invention relates to a liquefied gas storage tank and a marine structure including the same. The liquefied gas storage tank of the present invention, comprises: a buffer partition which is installed inside the liquefied gas storage tank and arranged adjacent to a side wall of the liquefied gas storage tank; a vertical support part which supports and fixes the buffer partition; a low density fluid control system which injects or collects low density fluid; and a damping part which is formed by the side wall and the buffer partition, and reduces sloshing impact load applied to the side wall by filling the low density fluid supplied from the low density fluid control system. According to the liquefied gas storage tank and the marine structure including the same, since a sloshing impact load reducing device is installed adjacent to the side wall of the liquefied gas storage tank, the sloshing impact load applied to the side wall of the liquefied gas storage tank caused by a sloshing phenomenon may be reduced, thereby securing stability of the liquefied gas storage tank and supersizing the liquefied gas storage tank. Also, since the sloshing impact load reducing device can partially be installed on the liquefied gas, there is no need to transform 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 완충격벽을 지지 고정하는 수직 지지부; 저밀도 유체를 주입 또는 회수하는 저밀도 유체 제어 시스템; 및 상기 측벽과 상기 완충격벽에 의해 형성되며, 상기 저밀도 유체 제어 시스템에서 공급되는 저밀도 유체가 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.
