Abstract
A work arm system for a submergible chamber wherein a plurality of work arms are rotatably mounted to the chamber and are retractably extensible, so as to provide a plurality of tools for work at a subsea station, such as an offshore wellhead station. One arm is provided with tool mounts at opposite ends, both ends being retractably extensible so that each end may alternatively be disposed to the subsea station. The present work arm system permits several work functions to be performed without resurfacing of the chamber.
