Latest Patents

One of her 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, along with a stress diverging part. This design reduces the convergence of stress in the main body by integrating a curvature into its internal face. By forming the corner area of the LNG cargo as a single body with a round-shaped curvature, her invention prevents stress convergence caused by hull deformation and thermal changes. This innovation eliminates the possibility of cracks in the secondary barrier and significantly improves its constructability. Additionally, it reduces the thickness of the primary barrier, enhancing reliability and decreasing overall weight compared to conventional designs.

Another significant patent by Ha-Na Yu is for a reinforcing member for the corrugated membrane of an LNG cargo tank. This invention aims to improve the pressure-withstanding properties of membranes with corrugations. The reinforcing member is installed in an insulating structural member of the LNG cargo, preventing the collapse of the corrugation and attenuating shocks without increasing the facial rigidity. This innovation also enhances the insulating properties
