Predictive Maintenance
The requirements on maintenance
International competition
Shorter product life cycles
Faster technological leaps
More complex business processes
Shift from product to service
Evolution of Maintenance Concepts
Reactive or Breakdown Maintenance
Preventive or Periodic Maintenance
Condition-based Maintenance
Unplanned production shutdowns
Inefficient use of resources
Simple rules Not very precise
Predictive Maintenance as an extension of condition-based maintenance
represents the informatization of production processes. With
intelligent IT-based production systems Predictive Maintenance
represents one important step on the path towards the development of a
Smart Factory in industrial production.
Predictive Maintenance
The future of maintenance
Predictive Maintenance Example – Gearbox Bearing damage in wind farm
• Reactive Maintenance
• Cost for a replacement of the bearing $ 250.000
• Cran costs $ 150.000
• Power generation / Revenue losses $ 26.000
$ 426.000

Predictive Maintenance Example – Gearbox Bearing damage in wind farm
• Predictive Maintenance
Use of acceleration sensors, oil particle counters and weather forecast modules,
plus reliable evaluation of the data
Early detection of the damage at the gearbox bearing
• Repair instead of exchange of the bearing $ 30.000 < $ 250.000
• Lower cran costs $ 75.000 < $ 150.000
• Power generation / Revenue losses $ 2.000 < $ 26.000
$ 107.000 < $ 426.000
