摘要： A cargo tank for an extremely low temperature substance carrier according to the present invention arranges a first cargo tank wall having a primary corrugated panel to prevent cracks caused by contraction and easily absorb impact caused by liquefied gas sloshing to prevent defects occurring in the cargo tank, forms auxiliary corrugation on each of the first, second and third cargo tank walls to prevent defects caused by contraction and more easily absorb impact caused by liquefied gas sloshing, and selectively applies the first to third cargo tank walls having different structures to respective parts of the cargo tank where different sloshing phenomena occur to improve reliability of the cargo tank.
