Objectives	To realise the benefits of this project, it is expected to finalise and publish an approved Industry specification, the draft document will need to be reviewed and updated in light of the comments received, through consideration of the extra learning now gained through field trials since the draft document was developed and with the knowledge of the new systems now starting to enter the market. The revised document will then be submitted throughthe formal TSF approval process to enable a Gas Industry approved specification to be published. Task 1: Review and update of the draft PE repair specificationThe review and update of the draft PE repair specification will be undertaken based on: Incorporation of the comments received through the TSF following submission of the draft document in 2016. Consideration of the comments received to date from the GDNs and potential suppliers. Consideration of any amendments based on the learning achieved through field trials of existing systems undertaken since the draft document was originally developed. Consideration of new repair technology/products to the industry, as well as those currently available. Further engagement with the participating GDN Engineering Policy teams and Operational Managers to ensure the suitability and sufficiency of the proposed performance testing requirements. Further engagement with the potential suppliers to ensure the practicality of the suggested performance requirements.New Scope change:Top tee damageInvestigate use of V-groove to create leak path through EF zone. Test up to 2 samples EF coupler Investigate use of V-groove to create leak path through EF zone. Test up to 2 samplesButt fusion standard damage sample Use of butt fusion tooling to confirm sample can be set up as defined in the draft specification with 2mm gapThe price includes all directs for additional pipe and fittings This project will allow the assessment of potential PE repair systems to be made in conjunction with the performance standard and enable approval for use of the repair techniques for this application. Following formal publication, the specification will provide a recognised route to approval for potential PE repair systems.
Abstract	GDNs currently respond to many leaks per year from PE pipes. These can be disruptive to both customers and the local environment. The use of permanent live application repair techniques could offer a significant reduction in the time taken to restore supply and considerably reduce the extent and disruption to the customer. Currently, there is not a fully approved PE Repair specification, which limits potential suppliers to gain the approval for use of appropriate repair systems.
