Development and Use of Underwater Work Systems

Subsea work systems are summarized. These systems range from tools used to salvage cannon from “Vasa” in 1628 to the capability of the “Glomar Challenger” to core-drill in 18,000 ft of water in 1969.

A variety of underwater work requirements are identified. Work systems, classified and described, include diving systems, submersibles, unmanned vehicles, and remotely controlled equipment.

A specific system is detailed which utilizes an underwater one-atmosphere manned work station, and a manned submersible equipped with a manipulation capability. Technical descriptions of subsystem characteristics and hardware photographs are provided.
