Summary of the contracting process

Northern Gas Networks Limited sought advanced leakage detection services for its gas network. The requirement was to use proven mobile and handheld detection technologies, supported by data analytics and integrated geographic information systems. The intended outcomes were improved operational safety, stronger asset management and reduced methane emissions. The procurement is classified as pipeline-inspection services and falls within the services category. The requirement relates to Northern Gas Networks’ network in the UK. The contracting process also contains several unrelated lot descriptions covering crane hire in Cornwall and Devon, nationwide equipment transport, regional land services and specialist land matters. These descriptions do not match the leakage-detection requirement and should not be treated as part of its technical scope.

The procurement has reached the awarded stage, but the tender status is complete and all six listed lots are marked cancelled. The leakage-detection requirement was Lot 1; associated active awards name Adsyst (Automation) Ltd, Cougar Automation Ltd, EJ Peak Technology Solutions Limited, Proeon Systems Ltd, RSE (Ross-shire Engineering Ltd) and Tata Consultancy Services, although the award records do not provide an award value or contract period for this requirement. The route was a selective negotiated procedure with a prior call for competition, with written submissions in English. Evaluation was recorded as commercial 40%, non-commercial 50% and cyber security 10%. The qualification system used Achilles UVDB registration, with possible Verify health, safety, environment and quality audits. Electronic auctions and a framework agreement were permitted.

This process indicates demand from a gas-network operator for specialist leakage monitoring rather than routine pipeline inspection alone. A credible future supplier would need mobile and handheld methane-detection capability, dependable data analytics and GIS integration, and the ability to turn survey results into practical asset-management and safety decisions. Demonstrable experience of working on utility or gas-distribution networks would be relevant, particularly where the service supports emissions reduction and proactive network management. Suppliers should also be prepared for the Achilles UVDB qualification route, annual subscription requirements and, where the buyer considers the risk level high, independent Verify assessment of health, safety, environmental and quality systems. The selection model shows that technical and service substance mattered at least as much as commercial terms, with cybersecurity also assessed.
