<p>Disclosed is a method for manufacturing a membrane for a liquefied natural gas cargo hold. According to an embodiment of the present invention, the method for manufacturing a membrane for a liquefied natural gas cargo hold comprises: a step for preparing a plate for a membrane having a first and second side; a step for forming a first forming plate by forming a corrugated part extended in parallel with the first and second sides in the plate for a membrane; a step for forming a second forming plate by forming a first concave part in the corrugated part to form a first area having a first curvature radius in the first forming plate; and a step for forming a first membrane by forming a second concave part in the corrugate part to be in neighborhoods with the first concave part to form a second area having a second curvature radius in the second forming plate. The size of the second curvature radius is smaller than the size of the first curvature radius.</p> |
