Objectives To produce a fit for technique and methodology to fully remove from risk Tier 2a (mandatory) stub ends connected to T2 and 3 Non2 mandatory pipes. Introduce a new product or service to the sector for decommissioning pipes in this category without the need for major customer disruption. Gain approval for product to be used on the gas network Introduce, from a remote location, an isolation technique that 100% removes stub end tier 2 pipes connected to tier 2 and 3 parent mains Ensure that the new technique complies fully with Stub End Policy and data is captured in recording systems.
Abstract Where a tier 2 pipe’s risk score exceeds the risk action threshold there is a requirement to remove the pipe from risk by abandoning the entire pipe. Leaving a stub of any length is un acceptable so cutting out a section of the parent main including the tee is the only compliant option available. Removal of the parent main, in many cases, can be extremely expensive, very disruptive to customers. It is often impractical to abandon these short sections due to traffic sensitivity or where normal working practices are unacceptable to stakeholders. To undertake a development and demonstration project with an SME (Steve Vick International) to produce a permanent abandonment process that removes fully the risk of Tier 2a pipes i. e. those above the Risk Action Threshold connected to tier 2 or 3 pipelines without requiring a full cut out of the parent pipe. Undertake an adaptation of the existing process "Remote foam bag for Tier 1 pipes" to ensure that the whole length of the tier 2a main is removed from risk.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
