Abstract
A cargo tank for a liquefied gas carrier ship includes: a main wall surrounding a receiving space in which the liquefied gas is received; a panel assembly surrounding the main wall; and an outer wall surrounding the panel assembly. The panel assembly includes: a plurality of first thermal insulating panels; a plurality of first auxiliary walls; a plurality of second thermal insulating panels fixed on second surfaces of the first auxiliary walls; a bridge pad disposed between the second thermal insulating panels; and a second auxiliary wall located between the bridge pad and the first auxiliary walls. The first thermal insulating panel and the first auxiliary wall are adhered to each other, and a first stress dispersion region prevents the first auxiliary wall or the second auxiliary wall from being damaged due to thermal expansions or contractions of the first thermal insulating panels and the bridge pad.
