Title:
Cryogenic-liquid tank
Document Type and Number:
Japanese Patent JP6155758
Kind Code:
B2
Abstract:
A low temperature liquid tank includes: a storage tank having a bottom portion obtained by joining a plurality of bottom plates; and a support portion supporting the bottom portion. The support portion includes: an outer support portion supporting a margin of the storage tank; and an inner support portion disposed inside the outer support portion and having a heat insulation in which creep occurs when a load is applied. An initial height of an upper surface of the inner support portion is set so that, during a service life of the low temperature liquid tank, maximum bending stress applied to the bottom plates due to a difference between a height of the upper surface of the inner support portion and a height of an upper surface of the outer support portion remains equal to or smaller than an allowable bending stress of the bottom plates.
