Latest Patents

One of his latest patents is an insulation panel for the corner area of an LNG cargo containment system. This invention includes a main body that constitutes the corner area of the cargo and a stress diverging part that reduces the convergence of stress in the main body. By forming the corner area with a round-shaped curvature, the invention prevents stress convergence caused by hull deformation and thermal changes, thereby eliminating the risk of cracks in the secondary barrier. This design also improves the constructability of the secondary barrier and reduces the thickness of the primary barrier, enhancing reliability and reducing weight compared to conventional designs.

Another notable patent is for a reinforcing member for the corrugated membrane of an LNG cargo tank. This invention aims to improve the pressure-withstanding properties of the membrane while preventing the collapse of the corrugation. By installing a reinforcing member within the insulating structural member of the LNG cargo, the invention attenuates shocks without increasing the facial rigidity of the corrugation and enhances the insulating properties by adding an additional insulating layer.
