An apparatus comprising:
- a curved structure having an exterior surface, having an interior surface and having a defect;
- a gasket positioned over the defect in the curved structure, the gasket having a length, a width and a thickness;
- a rigid patch positioned over the gasket, the rigid patch having a length, a width and a thickness, the length of the rigid patch being greater than the length of the gasket, the width of the rigid patch being greater than the width of the gasket;
- a block patch in between the rigid patch and the exterior surface of the curved structure;
- and
- a plurality of studs and nuts positioned near an outer perimeter of the rigid patch, the plurality of the studs being friction welded to the exterior surface of the curved structure.
