    Background: The Golf of Mexico, off the Texas coast, is the testing area for a new salvage device. Called pressurised sphere injection, the method costs a fraction of that expended on mechanical means of salvaging sunken vessels.

    The method employs a number of pressurised polyethylene balls that are injected into the hull of a sunken vessel. Correctly placed, the buoyant spheres will raised the vessel to the surface evenly.

    SYNOPSIS: Thirty-eight miles off the Gulf coast of Texas, a salvage ship prepares to raise a sunken barge, using a new method.

    Hollow plastic spheres are the main tool. The polyethylene balls are fed into a pressure chamber, where they are pressurised to give them extra buoyancy. Eighty pressurised balls will provide one ton of lift.

    Attempts to use unpressurised polyethylene in salvage operations have failed, because the material decomposed in underwater compression. Divers, working on the bottom of the Gulf, cut portholes into the hull of the barge. Holes are cut into each compartment of the hull, and a standpipe is fitted in.

    On the salvage vessel, fifty feet above, pressurised balls are forced into the conduit that feeds into the standpipe. The dives, working with the conduit, crisscross the beam, feeding the balls into the hull, so that the barge will rise evenly. The pressurised sphere injection system, as the process is called, costs much less than mechanical means of salvage.
