| Objectives | Design & Development (In-house) - SVI Design Engineers and Technical teams to design, develop and in-house test the following prototypes: Annulus entry systems - More than one method for gaining entry and injecting annular sealant into the metallic main will be designed to allow for several work scenarios. Sealant injection system - A small, non-disruptive sealant injection machine will be designed and developed to allow operators to transport the system through a customer’s property if required. The injection method should not require fuel powered hydraulic or pneumatic plant to operate. Field Trials - Field trials will be carried out in collaboration with the NGN Project Team and their field technicians. Information from the trials will be fed back to SVI design and development staff and acted upon accordingly until a successful, cost effective and safe system is developed. Field trials will be monitored by an SVI Project Manager and NGN Project Team representative. Project completion - The project will be deemed complete once the field trial stage has been completed successfully and all of the project criteria have been met. Upon field trial completion, an SVI Project Manager will produce the project completion report for review by the NGN and SVI Project Teams. Upon successful review, the Final Project Report will be published and presented to NGN. The project will be deemed successful if the following criteria are met: The system is transportable through a customer’s property. The system fully fills the annular space beneath a property and by at least 2m outside of the building lineInjection of sealant can be accomplished through varying connections to the annular space. It realises an increased ability to plan ‘Live Mains Insertion’ projects with built over properties in the vicinity. Enables the total decommissioning/abandonment of annular spaces beneath customer properties. Be deployable from remote, less sensitive areas within the customer’s private boundary as and when required. Reduce disruption to members of the public by abandoning annular spaces without the need to fully excavate them or carry out expensive and disruptive diversion work. Improve safety to members of the public. Cost benefits due savings made against main laying operations. Cost benefits due to the ability to abandon the annular space without the need of multiple excavations to allow main laying techniques such as diversions. Greatly improved customer relationship. Zero or very minimal waste is produced that will be removed by SVI Technicians. | |
| Abstract | A current problem found throughout the UK gas distribution networks (GDNs) is when a metallic gas main has been ‘Live Inserted’ using a new PE pipe but the metallic gas main runs beneath existing buildings. It is not common practice to ‘Live Insert’ gas mains that are under buildings but sometimes this is unavoidable and in some cases buildings are built over the gas main after it has been ‘Live Inserted’. In both cases the annular space between the new PE and the old metallic main has the potential to be a gas carrying leak path beneath the property which if ignored will be putting members of the public at greater risk of gas leaking into properties and potentially fires and explosions. The Annular Space Abandonment system will be developed by SVI and will require a number of in-house tests on different pipe diameter combinations to be carried out at SVI headquarters in Bradford on Avon. The testing will be witnessed by a NGN representative/project member and a full technical report detailing the project and its development will be produced by SVI.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
