CARGO FOR LIQUEFIED GAS

摘要

A liquefied gas tank having an insulation panel structure is disclosed. The liquefied gas tank, according to an embodiment of the present invention, comprises: a main barrier which surrounds a receiving space for liquefied gas; and an insulation panel assembly which surrounds the main barrier and insulates liquefied gas from the outside. The insulation panel assembly comprises: a lower insulation panel; an auxiliary barrier which is prepared in the lower insulation panel and seals the lower insulation panel; and an upper insulation panel which is stacked on the auxiliary barrier. The auxiliary barrier comprises: a plane part; and a corrugation part which is convex toward the upper insulation panel. A corrugation receiving pad, where a space for receiving the corrugation part of the auxiliary barrier is formed, is provided in the bottom of the upper insulation panel. Therefore, the present invention enables the easy installation and maintenance of the auxiliary barrier by allowing the corrugation part of the auxiliary barrier to protrude toward the upper insulation panel.
