Condition Monitoring, Maintenance & Inspection and Gas Distribution Networks
Phase 1 of this Project looked at the feasibility, design and development of a BSD which would enable the internal long range NDT inspection of buried Orpheus Regulator Modules without having to excavate or grit-blast the pipework.
Phase 2 of this Project involves collaboration with James Fisher Nuclear Limited (JFN) to design, manufacture and site trial the BSD; also completing the development of a long range NDT technique suitable for inspecting buried ORPHEUS Regulator Modules. The new BSD is expected to corrosion map 100% of the internal surfaces of 14”, 16”, 18”, 20”, 24” and 30” ORPHEUS regulator modules.
Site trials will be undertaken in the Scotland (SC) and South of England (SOE) Networks; all sites will be selected by SGN and jointly attended by SGN, JFN and a suitable Technical Service Provider (TSP) to assess suitability.
This Project has the following ‘key’ goals and objectives:
· Manufacture a BSD suitable for use on SGNs distribution networks
· Creation of specific Risk Assessment Method Statements (RAMS) and Training Packages for use with the BSDs (UT) NDT procedure
· Undertake offsite and live field trials to ensure the new BSD meets SGN requirements
· Validation and approval of the BSDs Ultrasonic (UT) NDT procedure; confirming that this new procedure fully meets SGN requirements
The key success criteria for the Project will be:
