Abstract
Method and apparatus for recovering a length of an electric cable from great depths of water in which a first device with a buoyancy tank and cable gripping jaws is lowered into the water and guided into position over the cable by an operator controlled submarine having manipulating arms. The tank is then released from the remaining equipment and rises to the water surface letting out a rope secured at its lower end to the remaining equipment. The operator then operates the jaws into gripping engagement with the cable. Thereafter, the rope is secured to a tensioning line on a surface ship, and a second device is lowered by the ship along the rope so as to settle in the remaining equipment, the latter being formed to fit into and with a cage at the bottom of the second device. The second device has a plurality of articulated clamping jaws which the operator operates into gripping engagement with the cable, and by raising the second device from the ship, a length of the cable is brought to the water surface. The cable may be cut by the operator before the length is raised.
