    • 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
    • 本发明的目的是提供一种非球形罐,其确保与球形罐相比足够的体积,同时确保针对由内部压力和外部压力引起的应力的足够的抗弯曲性,并且提供液化气体运输 装有这种非球形罐的容器。 因此,该非球形罐2具备:圆筒部31; 连续布置在圆柱形部分(31)上方的顶部部分(32); 和连续布置在圆柱形部分(31)下方的底部部分(33)。 顶部部分32具有球形壳部分35和桁架部分34,球形壳部分35由具有半径R1的球体的一部分形成并且布置在顶部部分32的上端处, ),其连续布置在圆柱形部分(31)上方并连续地位于球形壳体部分(35)下方,并且由具有小于半径R1的半径R2的球体的一部分形成,其中公式1.0
