Abstract: The present invention is related to a reinforcing member for a membrane for improving the pressure-withstanding property of the membrane having corrugations, and a membrane assembly having the reinforcing member and a method of constructing the membrane assembly. By providing a reinforcing member for a membrane having corrugations and installed in an insulating structural member of an LNG cargo, the present invention can prevent the collapse of the corrugation and attenuate shocks against a same load without increasing the facial rigidity of the corrugation, and improve the insulating property by forming an additional insulating layer.

Abstract: A fixing apparatus of a cargo insulation panel includes a fixing plate adhered to one face of an insulation panel, a plurality of fixing brackets protruded to the outside of the fixing plate, protruded portions of the fixing brackets fixed by stud bolts arranged on the hull, and a plurality of couplers configured to couple the fixing brackets to the fixing plate.

Abstract: A corner panel of an LNG cargo that includes a main body, which forms a corner area of the cargo, and a stress diverging part, which reduces the convergence of stress of the main body by being integrated with an internal face of the main body and being formed with curvature, and a secondary barrier formed in a curved shape.

Abstract: An insulation structure of a cargo tank in an LNG carrier and a method of constructing the insulation structure includes a first metal foil attached and installed in between the top insulation panel and the bottom insulation panel, a second metal foil attached to and installed on the first metal foil that is positioned on an upper side of a gap formed between the bottom insulation panels, and a top bridge panel attached to and installed on an upper side of the second metal foil.

Abstract: In a metal membrane for a low-temperature-fluid storage tank wherein longitudinal and transverse corrugations are formed and both corrugations intersect each other, a bidirectional expandable member connected to each corrugation is formed in the intersection of the corrugations so that the bidirectional expandable member is longitudinally and transversely expandable. The bidirectional expandable member is protruded and is shaped like a pyramid, a dome or a cross. Each metal membrane is welded into a unit panel and the edge of each metal membrane is welded with the common edge of another adjacent metal membrane.
