Live Stub End Abandonment
Live Stub End Abandonment is a technique offered by our Contract Service team for the final abandonment of live short stub ends of gas mains, typically 2 to 20 metres in length. The technique was developed by Steve Vick International in collaboration with National Grid Gas as a means of avoiding unacceptable disruption caused by excavation, for example at busy road junctions.
Using our proven resin foam technology in conjunction with CCTV equipment, it is possible to excavate down to the stub end from a non-sensitive location. It can then be rendered gas free from the point where it meets the parent main to the cap end previously fitted, preventing further leakage problems.
Benefits of Live Stub End Abandonment
- Enables short, live sections of unwanted main to be finally abandoned
- Abandonment carried out remotely from a nearby ‘non-sensitive’ position
- Ideal in locations in close proximity to petrol stations, hospitals etc, or other locations where disruption would be unacceptable
- Entire section filled with foam to avoid possibility of future leakage
- Trenchless technology – reduces excavation
- Carried out by Steve Vick International’s Contract Service teams
Process meets GIS/TE/E1.9 Specification.
