ABSTRACT:
A device is attachable to an outwardly extensible, rotatable arm of a manned submergible chamber and is formed with a horizontally pivoted gate to engage and hold a cable upon rotation of the arm. The device is provided with a track-mounted blade to sever the cable; the blade being actuated from within the manned chamber. In another embodiment, the device is capable of gripping the cable before severing, severing the cable and then permitting the severed cable to be lifted to the surface while continuing to grip the cable. The device is particularly useful for removing entangled cables from an underwater work area, such as an offshore drilling station.
