ABSTRACT:
An inflatable fluid-filled bladder for covering damaged areas of ship and barge hulls is disclosed. The bladder is lined on one side with a foam material which engages and seals the damaged area of the hull, and is covered on the opposite side with a wire net which positions and holds the bladder against the hull by means of suitable cables and winches. An edge frame to which the wire net is secured is provided around the bladder and an upstanding bracket is secured to the frame. Tension cables connected to the apex of the upstanding bracket exert pressure through the bracket legs to the edge frame to improve the seal between the edge of the patch and the surface of the hull.
