Abstract: The dimensions of the membrane tank are so selected that when it is cooled by liquefied gas charged therein and contracted, the flat portions may just contact with the inner surfaces of an insulating material lined over the inner wall of a shell structure. Restraining forces are applied to the membrane tank when the latter is installed into the insulating material structure. When the liquefied gas is charged into the membrane tank, the bending stresses generated are almost zero and the tank is subjected only to the hoop tensions.

Abstract: 1449634 Cryogenic tanks ISHIKAWAJIMAHARIMA JUKOGYO KK 21 Sept 1973 [22 Sept 1972 30 Jan 1973] 44349/73 Heading F4P A cryogenic tank comprises a membranous vessel 1 which, at ambient temperature, has dimensions greater than those of a rigid shell within which it is located so that it has to be deformed when placed in the shell at ambient temperature, the deformation being such that at the working cryogenic temperature the membranous vessel contracts to relieve bending stresses therein in order that the vessel is only subject to hoop tension at the low pressure. Numerals la, 1b, 1c in Fig. 4 show the membranous vessel as deformed at ambient temperature, undeformed at ambient temperature, and in its low temperature state respectively. Fig. 6 shows how various panels X, Y, Z, P are connected to form a membrane.
