Success for STASS

Synthotech’s STASS robot proving capable as field trials get more demanding.

The System Two Assess & Seal Solution (STASS) project is a robotic crawler platform that is designed to assess the condition of joints in cast iron mains gas pipes, and to spray sealant fluid into the joint as a leak prevention technique. The STASS project is a Network Innovation Allowance (NIA) funded innovation project for Northern Gas Networks (NGN) and brings together a combination of three gas network approved technologies; ALH ‘Bond & Bolt’ access system, Synthotech’s Synthotrax™ robotic platform, and ALH Flexspray sealant.

The STASS project is currently undergoing a gruelling field trial regime after the success of the first field trial back in November, where the STASS robot accessed 10m of pipe and sprayed 3 joints in a single direction. The second and third field trials saw the STASS robot reliably access 27m and spray 9 joints in a single direction, despite large debris deposited in the pipe, and achieving this in a record time of 4 minutes per joint.

From here on, the field trial requirements get more demanding, with the upcoming field trials really pushing the distance and joint capability of the robot.
