A double-shell tank (3) mounted in a hull of a liquefied gas carrier includes: an inner shell (4) including an inner shell main structure (41) and an inner shell dome (42); an outer shell (5) including an outer shell main structure (51) and an outer shell dome (52); and a support located between the outer shell main structure (51) and the inner shell main structure (41). The outer shell dome (52) is divided by a bellows (55) into a fixed portion (52A) and a movable portion (52B). The movable portion (52B) is coupled to the inner shell dome (42). A tank cover (7) includes a tubular portion (72) that is passed through by the outer shell dome (52). An elastic body (8) is located between the tubular portion (72) and a dome flange (56). The dome flange (56) is located on the movable portion (52B) of the outer shell dome (52). Displacement measurers (9) to measure a displacement of the movable portion (52B) of the outer shell dome (52) relative to the tank cover (7) are located on a circumference surrounding the outer shell dome (52).
