As part of the Cadent Technical Consultancy Framework, QEM Solutions were awarded the opportunity to carry out a feasibility Study on teh Holford Gas Storage Facility.
Cadent operates the facility in Cheshire which is fed from a Distribution site at Warburton in Cheshire. It was installed in 1982 and the existing control system has now been identified as being no longer fit for purpose. This is, in part, due to the age of the site equipment. As with all control systems technology has moved forward and Cadent now has a requirement to replace the mechanical plant, Instrumentation control and monitoring system. The original design is based around pneumatic controls with the Fill and Empty cycles being initiated from the Cadent Distribution National Control Centre (DNCC) at Hinckley, Leicestershire.
QEM's remit was to produce a detailed feasibility study on the possible options available to replace the existing control systems (both mechanical and E&I assets) that are used import and export gas into the high pressure storage facility located at Holford in the North West of England.
This report examined the options available for replacing and/or upgrading the volumetric control systems, instrumentation and telemetry systems associated with the Holford / Warburton 2 cavity fill and emptying operations.
The report aimed to provide Cadent with sufficient information to decide their preferred options for further investigation at feasibility and to progress to conceptual and detail design.
Due to the complex nature of the salt storage cavity controls, QEM Solutions worked with 2 of the UK’s leading design houses, Grange Industries and Rush Construction to investigate various, up to date, solutions.
