ABSTRACT:
A manned or remotely controlled submergible chamber or tool carrier is provided with tool connection and disconnection to the work arm at an underwater location. A plurality of tools are mounted in a rack and each tool may be selectively connected and disconnected to a hydraulic drive means at the outward end of the retractably extensible portion of the work arm. All tool changing operations are remotely controlled from within the chamber or a remote station, as the operator views the tool changing operation. This tool system permits continuity of work arm operations without the need for the chamber to surface for tool changing. This tool changing system is particularly useful in performing work functions on underwater wellheads.
