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 an insulation panel assembly which surrounds a main barrier for surrounding a liquefied gas receiving space and insulates liquefied gas from the outside. The insulation panel assembly comprises: a lower insulation panel which is installed in an outer wall; an auxiliary barrier which is formed in the lower insulation panel to seal the lower insulation panel and has a plate part and convex corrugation parts protruding in a direction that the main barrier is installed; and an upper insulation panel which is stacked on the auxiliary barrier and has receiving grooves for receiving the corrugation parts of the auxiliary barrier in the bottom. Therefore, the present invention enables the easy installation and maintenance of the auxiliary barrier by allowing the corrugation parts of the auxiliary barrier to protrude to the upper insulation panel.
