INSULATION STRUCTURE OF LNG CARGO

摘要

PURPOSE: An insulation structure of LNG cargo is provided to prevent the deformation of ribbed parts by forming a reinforcing ribbed part in every ribbed part. CONSTITUTION: An insulation structure of LNG cargo comprises a ribbed part(110) and a reinforcing ribbed part(120). The ribbed part with a stepped portion(104) is formed in a membrane(100) of a first barrier of the LNG cargo. The reinforcing ribbed part is attached to the stepped part inside the ribbed part and includes a flat surface of a semicircular or polygonal profile and a convex surface extended from the flat surface. An elastic filler is installed between the ribbed part and the reinforcing ribbed part.
