  • Sealing openings in hulls of vessels
    Patent number: 5782196
    Abstract: A remotely-operated unmanned vehicle attached to the hull of a marine vessel by electromagnets surveys the hull for damage. The vehicle attached to the hull is electronically controlled from a remote location. An imaging system on the vehicle provides an operator with images of the vessel's hull and the surrounding environment. Once damage has been found and assessed, the vehicle applies a patch over the damaged opening in the hull to prevent cargo outflow and water inflow. The patch, which resists puncturing and tearing, is constructed from one or more sheets of flexible material having dimensions appropriate to cover most openings.
    Type: Grant
