LIQUEFIED GAS-STORING TANK AND LIQUEFIED GAS TRANSPORT VESSEL

摘要

A liquefied gas storage tank (2) includes: an inner shell (3) storing a liquefied gas; an outer shell (4) forming a vacuum space (20) between the inner shell (3) and the outer shell (4); and a fail-safe thermal insulating layer (6) covering an outer side surface of the outer shell (4). According to this configuration, the fail-safe thermal insulating layer (6) is not disposed in the vacuum space (20). This makes it possible to suppress the degradation over time of the degree of vacuum in the vacuum space (20).
