| Objectives | The objectives of this project are to: To validate the tape as a robust repair solution. Establish cost benefit and efficiency improvements in terms of reduced time for repairs and reduced disruption for customers. Training material provided in support of field trials. SGN to carry out field trials to comprehensively review the new repair technique and provide a technical report for the other Licensees to disseminate the outcomes of the field trial. Provide installation method statement and record template in order to document every individual repair. Detailed costs benefit analysis from the field trials. The success criteria for this project are to trial and test the method against the traditional methods currently used to compare its performance in terms of: Demonstrate onsite suitability as a temporary repair technique. Provide an in service track record which can be used as justification or otherwise to increase inspection intervals and classify self amalgamating tape as an interim repair. Demonstrate repair longevity or otherwise. Capture a case study on the avoidance of replacement in terms of environmental and customer benefits. Increase in productivity. | |
| Abstract | Scotia Gas Networks (SGN) has an estimated 188,000 network risers within multi-occupancy buildings across our Scotland and Southern license areas. There is a high inherent risk of major incident with this asset group. The majority of network risers are constructed of materials and fittings that are subject to deterioration and ultimately failure. The route cause of failure can take different forms, be it from corrosion, fatigue and stressfrom thermal expansion, electrical fault conditions, fire or vandalism. The impact of failure varies significantly based on a number of factors, such as where on the riser it has failed, where the riser is within the building, what the building layout is in terms of access and egress, what the likelihood that escaping gas will result in a public reported escape, the occupancy level of the building, the vulnerability of the occupants and other social and environmental factors. Approximately 572 riser supplies were cut off and replaced in 2011/12. SGN’s network riser replacement strategy for the RIIO price control is estimated to be approximately £108m subject to risk managed output. It therefore presents an excellent outperformance opportunity with regards to the total Repex allowance. In order to avoid the high cost associated with traditional riser replacement, the aim of this project is to evaluate a solution to repairing screwed joints, up to 2" diameter only, on network risers and lateral pipework. This project allows the field trial and performance evaluation of self amalgamating tape as a repair activity for screwed joints up to 2" diameter on riser and lateral pipework to be undertaken, which will ensure a safe and reliable gas supply to our customers and limit the need to replace network risers and lateral pipework in RIIOGD1.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
