A method for repairing a damaged area of a hull of a water vessel includes providing a patch assembly having (i) a first flexible outer layer, (ii) a second flexible outer layer and (iii) an inner layer of composite material sealed between the first flexible outer layer and the second flexible outer layer. When the inner layer is heated and then cures, the composite material transforms from a flexible uncured state to a fixed cured state. With the composite material in the uncured state, the patch assembly is positioned at a damaged area of a hull of a water vessel and conforms to a shape of the hull. An electric heating element is electrically operated to heat the inner layer, and when the inner layer is cured, the composite material is cured, where the shape of the inner layer is fixed relative to the shape of the hull.

A device for sealing an opening in a wall includes at least one flexible, deformable balloon; a locking bar that is slidable into the opening of the wall from one side of the latter and engages with the opposite side of said wall; a plate capable of bearing on the at least one balloon and of sandwiching same against the wall; and a flexible connecting rope located between the locking bar and the plate and that passes through an inner duct of the balloon and is capable of compressing the balloon against the opening.
