Centrica Storage Limited operates the Rough gas storage facility onshore gas processing terminal in East Yorkshire. It is a wholly-owned subsidiary of Centrica plc, an integrated energy company which also includes British Gas, Centrica Energy, Centrica Storage and Direct Energy. Operating in 7 countries, Centrica works both upstream - source, generation, process, trade and store - and downstream - supplying gas and electricity to millions of homes.
With ageing equipment and an expected increase in demand for its services, Centrica Storage required greater confidence in the availability and capability of its equipment to supply gas. They needed to improve the way they predicted age related failures, reflected any likely failures in scheduling and maintenance plans, and built preventative maintenance schedules to ensure optimum availability of equipment.
LSC Group embedded a specialist within the Centrica Storage team to develop a modelling capability that would allow Centrica Storage employees to deliver a comprehensive reliability model. The model presented the relationships between reliability, maintenance and sparing of their equipment and allowed powerful scenario testing against demand.
The advanced reliability model developed by LSC Group allowed Centrica Storage to better understand the dependencies between the key factors affecting the reliability of the plant and its related equipment.
Specific benefits included:
Opportunity to reduce time and cost of undertaking less optimum maintenance activity
Understanding the relationships and trends associated with the plant (reliability, maintenance and sparing)and the impact of a change in demand would allow Centrica Storage to make more informed decisions as to how they better manage their ageing equipment. The model would help to develop an optimum maintenance and sparing solution to ensure equipment availability.
