There are disclosed a tank having a structure which achieves both a burst strength and a fatigue strength, and a manufacturing method of the tank. In order to realize this, in a tank comprising a liner, and an FRP layer including a hoop layer and a helical layer formed by winding fibers around the outer periphery of the liner, at least an innermost helical layer is formed as a smooth helical layer. When the smooth helical layer, i.e., a helical layer which does not have any unevenness or which has only little unevenness is formed, the unevenness can be prevented from being transferred to the hoop layer adjacent to the helical layer. When structural bends (undulations) of the fibers of the hoop layer are suppressed, a fatigue strength of the fibers themselves can be enhanced.

A toroid pressure vessel includes a toroid body having an inner shell and an outer shell. The toroid body includes a toroid outer perimeter. The outer shell extends along the toroid outer perimeter. A planar exterior face extends along at least a portion of the outer shell and the toroid outer perimeter. A support belt circumscribes the toroid outer perimeter and is coupled along the planar exterior face. The support belt braces and supports the pressure vessel along the toroid outer perimeter against bulging force (and hoop stress) generated by pressurized fluids within the vessel. The support belt facilitates the use of thinner pressure vessel shells and thereby decreases the weight of the pressure vessel while providing a support to the outer shell that substantially prevents deformation of the planar exterior face.

INSULATION PANEL FOR CORNER AREA OF LNG CARGO CONTAINMENT SYSTEM

Номер: US20170038007A1
Принадлежит:

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. 1. A corner panel of an LNG cargo , comprising:a main body arranged at a corner area of the cargo, an internal face of the main body having curvature;a stress diverging part including a curvature member and configured to reduce convergence of stress of the main body, an external face of the curvature member being adhered to the internal face of the main body; anda primary barrier adhered to an internal face of the curvature member.2.
