| Objectives | The aim of this project is to deliver a feasibility investigation into the practicalities and benefits of a technological solution to facilitate the remote connection of a replaced PE service and a PE replacement main inserted in a metallic carrier pipe, within the context of the TORS initiative. This feasibility investigation will build on the proof of concept work undertaken in a previous IFI project. Success of this project will be the delivery of the feasibility study which assesses the TORS technique and informs of the practicality and benefits of the identified solution for use on remote connections. | |
| Abstract | Current methods of replacing Tier One gas distribution mains are costly, disruptive to customers and road users. This project seeks to determine a method of achieving the outputs of mains and service replacement with increased customer satisfaction and whilst being quicker and cheaper than current methods. The renewal of mains and services within a street could be possible via two single excavations, one at each end of the street, this would result in reduced cost and effort, improved safety, environmental benefits through reduced waste to landfill and reduced customer and third party disruption, leading to improved customer satisfaction. A common method of replacement of gas mains and services involves excavation and flow stop onto the main at either end of the area to be renewed, in order to decommission the existing pipe work. Further excavations are then opened where each service connects to the decommissioned main, usually within the public highway, to remove the existing mains to service connection to affect the renewal of the replacement gas services. The old metallic main is then inserted with a replacement Polyethylene (PE) main that is pressure tested, commissioned and reconnected to the network, whilst all the services are replaced, pressure tested and then commissioned. This is followed by the reinstatement of all excavations. This project will undertake a feasibility investigation into the practicalities and benefits of a solution, to facilitate the remote connection of a replaced PE service and a PE replacement main inserted in a metallic carrier pipe. This feasibility investigation will build on the proof of concept work that was undertaken in a previous Innovation Funding Incentive (IFI) project. This previous IFI project was commissioned to prove the concept of a remote connection, in which a remote connection between a 25mm PE service inside 1 1/4" steel service via an in-line side entry connection to a 250mm PE main inserted inside a 12" carrier metallic pipe was successfully achieved. Within this project it is proposed to target a further demonstration, this time focussed on a more complex service connection and smaller replaced and carrier mains sizes. In addition this project will consider practical application methodologies to facilitate a next level benefits analysis.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
