This paper describes a sub-sea hyperbaric Post Weld Heat Treatment (PWHT) system developed jointly by SHELL UK EXPLORATION and PRODUCTION and COMEX DIVING. It discusses: assessment of power requirements and equipment, initial tests conducted in the COMEX hydrosphere and in shallow water in Marseille, and full scale North Sea trials at - 150 m, comparing the performance and results of two separate power sources and control units. Particular attention is drawn to the importance of the elements, insulation and controls used to achieve uniform distribution of heat at the required temperature in a HELIOX environment.
