본 발명은, 내압과 외압에서 기인하는 응력에 대한 내좌굴성을 충분히 확보하면서, 진구상 탱크와 비교하여 용적을 충분히 확보한 비진구상 탱크 및 그것을 구비한 액화 가스 운반선을 제공하는 것을 목적으로 한다. 이를 위해서, 원통부 (31) 와, 원통부 (31) 의 상방에 연속하도록 배치되는 정상부 (32) 와, 원통부 (31) 의 하방에 연속하도록 배치되는 바닥부 (33) 를 구비하고, 정상부 (32) 는, 반경 R1 의 구체의 일부에 의해 형성됨과 함께 정상부 (32) 의 상단에 배치되는 구각부 (35) 와, 원통부 (31) 의 상방 및 구각부 (35) 의 하방의 각각에 연속하도록 배치됨과 함께 반경 R1 보다 작은 반경 R2 의 구체의 일부에 의해 형성되는 트러스부 (34) 를 갖고, 1.0 < R/H1 < 1.5 를 만족하는 비진구상 탱크 (2) 를 제공한다. 여기서, R : 원통부 (31) 의 반경, H1 : 정상부 (32) 의 연직 방향의 높이이다.

    The objective of the present invention is to provide a non-spherical tank that ensures an adequate volume in comparison with a spherical tank, while ensuring adequate buckling resistance with respect to stress caused by internal pressure and external pressure, and to provide a liquefied gas transport vessel equipped with this non-spherical tank. Therefore, this non-spherical tank (2) is equipped with: a cylindrical section (31); a top section (32) arranged continuously above the cylindrical section (31); and a bottom section (33) arranged continuously below the cylindrical section (31). The top section (32) has a spherical shell section (35), which is formed by a portion of a sphere having a radius R1, and is arranged at the upper end of the top section (32), and a truss section (34), which is continuously arranged above the cylindrical section (31) and continuously below the spherical shell section (35), and is formed by a portion of a sphere having a radius R2 smaller than the radius R1, wherein the equation 1.0 < R/H1 < 1.5 is satisfied when R is the radius of the cylindrical section (31) and H1 is the height of the top section (32) in the vertical direction.
