Remotely operated lift system for underwater salvage

摘要

A system for retreiving undersea salvage items from a sub-surface location. The system includes a flotation unit, winch, related remote control unit and a power supply mounted thereon, a winch, related remote control unit, and a power supply mounted on the support element. A cable or equivalent secured to the winch includes a retrieval harness or alternative means such as a shackle for securing the salvage item to the winch. A tether connects the system to a remote salvage tender on the surface. An adjustable and automatic stop is provided by the control unit to prevent certain types of salvage from rising beyond a desired depth or breaching the surface. Portions of the system used in magnetic mine retrieval are fabricated of non-magnetic material.
