A Submersible Work Chamber for Subsea Production Systems 700776

To enable man to effectively install and maintain the components of a subsea oil production system at any depth has required the abandonment of conventional diving equipment and techniques. The submersible work chamber and its associated components enable two operators to descend to the sea floor installation with the capability of performing specific tasks. These tasks have been substantially simplified by departing from the use of conventional connector attachments and their associated operating equipment. Problems encountered in making pipeline connections, hydraulic connections, and electrical connections underwater have been combined and solved by the design and construction of a single hydraulic tool operating in conjunction with the submersible work chamber.
