Mimic helps avoid maintenance-induced machinery failure
Machinery: Main engine oil pump
Sensor data used: Vibration
Before overhaul: Machinery operating within normal vibration limits - no requirement to perform maintenance.
Planned overhaul: Full overhaul of machinery conducted, as per planned maintenance schedule.
Post overhaul: Mimic CM technology detected vibration readings well above defined thresholds, sending the machine into alarm. Further inspection/overhaul is now required, or there is a high risk of machinery failure.
- Scheduled planned maintenance is not always required due to the actual functioning condition of the machinery.
- Performing unnecessary maintenance can lead to wasted labour hours and spare parts.
- Planned maintenance can lead to maintenance-induced failure.
- CM can identify early onset of machinery failure.
- Reviewing all CM information prior to intrusive maintenance work can mitigate the decision to defer the task.
- Importance of gaining Classification Society CM notation - the planned maintenance activity could be replaced by CBM, so maintenance would only take place when the condition of the machinery dictates.
