A few important thoughts on failure modes and distributions, recently discussed on Linkedin platform. Components fail either because they do wear out (right side of the bathtub curve), and it is possible to estimate their safe life limit or economic life limit (ref. Moubray RCM II). Or they fail because quality defects in the manufacturing...

This is one of the key prerequisites for achieving higher uptime of equipment (reducing repair times), yet balancing the supporting costs of spare parts and materials. Doing it right, means doing more with less: knowing which parts and how many may be needed, which will produce optimum financial results, as opposed to the (more industry...

What will RCM analysis show when performed on critical assets with a strong (and a bit expensive) current maintenance strategy, with high levels of asset reliability performance? Majority of CBM and PM tasks already included in maintenance schedules; Failure mode coverage with the existing maintenance strategy – between 75% and 85%; Non-optimized task frequencies (some...

Great quote from a fellow consultant Simon Murray

Make sure the MTBF is calculated correctly, before it can be used for further analysis. Two very practical uses of MTBF: Estimate/predict the number of failures (i.e. amount of corrective work) in any point of time in future – the larger the projected time window the higher the accuracy of failure predictions). By narrowing down...
