Abstract: A method of repairing a section of a pipe including a breach in the pipe. A surface of a wall of the pipe is prepared generally around the breach. A piece of conformable material of the type capable of carrying a curable polymer is sized in relation to a size of the breach. The sized piece of conformable material is applied to the prepared surface so that the breach is covered by the piece of conformable material. The piece of conformable material is impregnated with a curable polymer. The curable polymer is cured within the piece of conformable material thereby to seal the breach against egress of groundwater into the pipe.

Abstract: A protective casing for a vessel includes an outer shell surrounding the vessel wall. A spacer extends from adjacent the vessel wall toward the outer shell and spaces the outer shell away from the vessel wall. The spacer permits substantially uninhibited deformation of the outer shell to failure inward toward the vessel wall when a missile impact is imparted on the outer shell such that the outer shell substantially dampens the transmission of the energy of the missile impact to the exterior vessel wall. The spacer can position the outer shell to allow reinforcing fibers of the outer shell to elongate to the yield point to maximize energy absorption. Embodiments of the protective casing and a protected vessel, as well as a kit and method for forming the protective casing, are disclosed.
