NON-SPHERICAL TANK AND LIQUEFIED GAS TRANSPORT VESSEL EQUIPPED WITH SAME

WIPO Patent Application WO/2016/163209

A1

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.
