Frequently Asked Questions
CBM is a proactive maintenance strategy that relies on monitoring an asset’s condition to determine maintenance needs. Unlike preventive maintenance with fixed schedules, CBM only triggers maintenance when data indicates a decline in performance or an impending failure.
CBM assesses the condition of the machinery while it’s running and enables engineers to make interventions to keep it that way. Time-based maintenance, on the other hand focuses on maintaining equipment according to a regular schedule.
Benefits include reduced maintenance costs, minimized downtime, optimized equipment performance, increase in service life of plants, optimization of spare parts management and improved reliability.
The first steps involve identifying critical equipment, choosing monitoring techniques, and establishing data analysis procedures.
CBM is well-suited for critical assets where failures can be costly. It can also be beneficial for equipment with predictable failure modes.
CBM is well-suited for critical equipment where failures can be costly. It can also be applied to non-critical assets to optimize maintenance efficiency.
Data collection frequency depends on the criticality of the asset and the chosen monitoring technique. It can range from continuous monitoring for critical equipment to periodic checks.
Monitoring techniques include:
- Visual inspections
- Performance data analysis (often from sensors)
- Scheduled tests (vibration analysis, oil analysis, )
