The present invention is related to a corner panel of an LNG cargo that includes a main body, which constitutes 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. Therefore, by forming the corner area of the LNG cargo in a single body having a round-shaped curvature, convergence of stress caused by the deformation of the hull and thermal deformation can be prevented, and possibility of crack in a secondary barrier can be removed. By allowing the secondary barrier to be formed in a curved shape, the constructability of the secondary barrier can be greatly improved. Since no hardwood key or plywood is required, the thickness of a primary barrier can be reduced as the stress is decreased and the reliability of the secondary barrier is improved, and the weight can be greatly reduced over the conventional cargo corner area.

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.

A method is disclosed for testing bonded part integrity of bonded structures with increased sensitivity and in a nondestructive manner. The method includes the steps of: mixing a piezoelectric material or an electrically conductive material with an adhesive agent, curing the adhesive agent in between bonding target objects, electrically connecting the bonding target objects to one another, causing an electric current to flow through the bonding target objects to measure a quantity of electric charges flowing between the bonding target objects, and determining existence of bonding damage between the bonding target objects and the adhesive agent based on the quantity of electric charges and predicting a remaining life span of the bonded structures based on a data indicating a correlation between the quantity of electric charges and a predetermined fatigue life.
