Gas Transmission Networks
This project looks to promote a reduced plan for excavations based on an increase to the superficial limit for grade L555 pipe, which could have the following environmental benefits:
- Less local environmental nuisance from noise, dust, light pollution, road traffic.
- Less use of natural resource, such as backfill, fuel for plant, fuel for staff transport.
- Less risk of damage to wildlife habitats
- Less risk of impacts on areas of outstanding natural beauty and Sights of Special Scientific Interest (SSSI)
The benefits derived from a removal of unnecessary remedial actions will be realised through cost avoidance in the region of £200k to £10m. The figures are dependent upon level of disruption of service, where excavation requires outages or an agreement for reduction of pressure as outlined below. An environmental benefit would also be realized from the prevention of pipeline excavation, delivering a carbon savings of 21,000 tonnes of CO2e per repair.
