CARGO FOR LIQUEFIED GAS

摘要

Disclosed are a liquefied gas tank including a barrier having corrugation parts, and a manufacturing method thereof. The liquefied gas tank according to an embodiment of the present invention, which is installed in an outer wall including corner parts and a flat plate part, comprises: lower insulation panels for a corner part which are installed to be adjacent to the corner parts; lower insulation panels for a flat plate part which are installed to be adjacent to the flat plate part in first and second directions; auxiliary barriers for a corner part which are stacked on the lower insulation panels for a corner part to seal the lower insulation panels for a corner part; and auxiliary barriers for a flat plate part which are stacked on the lower insulation panels for a flat plate part to seal the lower insulation panels for a flat plate part, wherein one or more from the corrugation parts of the auxiliary barriers for a corner part are arranged to not meet the corrugation parts of the auxiliary barrier for a flat plate part, and wherein the ends of the corrugation parts of the auxiliary barriers for a corner part arranged to not meet the corrugation parts of the auxiliary barrier for a flat plate part are connected to the plane parts of the adjacent auxiliary barriers for a flat plate part to maintain a sealed state.
