A liquid cargo storage tank according to an embodiment of the present invention includes a main tank including a partitioning wall for partitioning a space, and stringers individually connected to inner walls and a partitioning wall of the main tank in a horizontal direction and traversing the main tank. The stringer includes: first members connected the inner walls of the main tank and second members connected to the partitioning wall. The projected length of the first member is longer than the second member to have a cross sectional area larger than the second member. The liquid cargo storage tank according to the present invention changes the shape of the stringer according to a position of the main tank where the stringer is installed like enlarging the cross sectional area of a part of the stringer where a dynamic load of a liquefied gas generates large and reducing the cross sectional area of a part of the stringer where the dynamic load of the liquefied gas generates relatively small. Accordingly, the liquid cargo storage tank is capable of preventing the cross sectional area of the stringer while reducing the sloshing phenomenon, thereby preventing an increase in the whole load of a vessel.

    본 발명의 일 실시예에 따른 액체화물 저장탱크는, 공간을 구획하는 격벽부재를 포함하는 메인탱크; 및 상기 메인탱크의 내벽 및 상기 격벽부재 각각에 수평방향으로 가로질러 연결되는 스트링거를 포함하되, 상기 스트링거는, 상기 메인탱크의 내벽에 연결되는 제1 부재; 및 상기 격벽부재에 연결되는 제2 부재를 포함하며, 상기 제1 부재는 상기 제2 부재보다 단면적이 크게 이루어지도록 상기 제2 부재보다 돌출길이가 큰 것을 특징으로 한다. 본 발명에 따른 액체화물 저장탱크는, 액화가스의 동하중이 크게 발생되는 위치 상에 단면적을 넓게 하고, 상대적으로 동하중이 작게 발생되는 위치 상의 단면적을 줄이는 바와 같이, 메인탱크에 설치되는 위치에 따라 스트링거의 형태를 달리 이루어, 슬로싱 현상을 감소시키면서도 스트링거의 단면적이 불필요하게 넓어지는 것을 방지하여 선박의 전체 하중이 증가하는 것을 방지할 수 있다.
