Introduction: All gas network operators aim to operate their networks in a safe and efficient manner. Despite an ongoing transformation to plastic pipe, we still have over 80,000km of Great Britain (GB) gas distribution mains are metallic and subject to aging and deterioration. They are costly to operate and require continuous inspection, repair or replacement.

The Project scope will cover:

• Detailed design and manufacture of modular robotic platforms

• Development of management and operational procedures

• Full testing to ensure the robots can be operated safely inside a live gas pipe

• A detailed commercial appraisal.

Objectives: Its objective is to develop new robotic technologies which operate inside the live gas main which can not only remotely repair leaking joints, but support our pipe fracture risk management process through enhanced inspection in larger our diameter pipes.
