Chapter 16. Quantified Reliability Centered Maintenance
16.1. What is QRCM?
Quantitative Reliability Centered Maintenance (QRCM) involves calculations to balance the cost of excessive maintenance against that of the unavailability arising from insufficient maintenance. The following simple example illustrates one of the techniques that will be dealt with in this chapter.
Doubling the proof-test interval of a shutdown system on an off-shore production platform might lead to an annual saving of 2 man-days (say £2000). The cost in increased production unavailability might typically be calculated as 8×10–7, in which case the annual loss would be 8×10–7×say £50 (per barrel)×say 50000 (barrels)×365 (days)=£730. In this case the reduction in maintenance ...
