Pressure and Process Plant Technical Group (TG5)

The Pressure and Process Plant Technical Group covers a wide range of industries both on and offshore, and throughout the entirety of an assets lifecycle.

The design and ongoing integrity management of process and pressure systems is vital in ensuring that both safety and business risks are kept as low as reasonably practicable, accounting for both regulatory and financial constraints. This comes increasingly into focus where plant is required to operate beyond its intended design life, and the maintenance, integrity and safety functions have increasingly critical roles to play.

This Group represents a forum for engineers involved in the design, fabrication, operation, maintenance, inspection, safety and management of critical pressure and process plant to both learn and share their experiences, to network and keep up to date with the latest developments on enduring themes or new technologies and techniques.

The Group will cover codes, standards, practices and research, and will encourage participants to bring their topics of concern or interest to the forum, providing the opportunity to influence direction, ensuring the Pressure and Process Plant Technical Group will be as relevant as possible.

Meet the TG5 Chair

Chris Scales BSc CEng FIMMM SenMWeldI

Chris graduated in Metallurgy from the University of Manchester in 1994. He now has over 27 years of experience in industry, in the areas of Metallurgy, Welding, Corrosion, Inspection and over the last 10 years, as a Specialist Inspector in Materials and Corrosion with The Health and Safety Executive’s Energy Division. Beginning at CAPCIS in Manchester, Chris learned the fundamentals of failure investigation. Moving to join OIS plc in Aberdeen in 1998, he worked as a Metallurgist, providing services to numerous Oil and Gas operators both on and offshore.

Following a short spell working for a Marine Engineering company in Birkenhead, Chris moved to BAE Systems Submarines in Cumbria as a Principal Engineer in the Metallurgy and Welding department. For 12 years, he was involved in the design and build of the Navy’s Astute class submarines, as well as supporting other in-service surface vessel and submarine types. Whilst at BAE Systems, Chris provided manufacturing engineering support to Land Systems, and their large calibre weapons systems for the UK MoD and other customers.

For the Health and Safety Executive, Chris now inspects, investigates and regulates the UK Offshore Oil and Gas industry, ensuring Operators comply with Major Accident Hazard regulations and that the risks associated with production and processing systems are kept as low as reasonably practicable. His remit also now includes assisting to develop the government’s regulatory framework for Net Zero-related energy technology.

Having spent a number of years sitting on the MoD’s Defence Standards Corrosion Committee, Chris is currently involved in the HOIS (Inspection) JIP and the Energy Institute’s Corrosion Management and Asset Integrity Committee.
