LNG DOUBLE METALLIC BARRIER APPARATUS FOR CARGO CONTAINMENT SYSTEM OF LNG CARRIER AND THE MANUFACTURING METHOD THEREOF

摘要

The invention LNG to make available to the double metal minimized and when panel installation state for a partition wall structure with a minimum of machining of the panel, and the primary partition wall a metal membrane secondary partition wall (secondary barrier) used in the (primary barrier) double metal partition wall device for a cargo carrier, and relates to a manufacturing method thereof, The LNG carrier cargo hold of a double metal partition wall device for is, the second partition wall which is that the second panel is installed is flattened the leveling wedge-mediated connection to the hull is formed; The secondary edges are fixed on the top of the first panel of the partition wall, the upper primary partition wall in which a metal membrane is welded to the formation; And the first panel including a first panel, a nut securing the upper end of the first panel, the fixing bolt and the one of the primary panel edges positioned around the primary panel fixing bolts which are disposed at the same position on the surface of said second panel It is configured to include; fixing Double metal minimize the partition fixing portion when panel installation for a structure to minimize the machining of the panel, and the manufacturing and installation to overcome the corresponding difficulties at the time of thermal deformation in the case where the fixed-point number in a cryogenic environment, hold for LNG carriers cost It provides an effect to decrease.;
