Commissioning
Commissioning is the controlled process of verifying that new or modified equipment is installed correctly, performs as intended, and is ready for safe operation.
What this term means in maintenance
Commissioning is the controlled process of verifying that new or modified equipment is installed correctly, performs as intended, and is ready for safe operation.
Commissioning activities
Commissioning may include:
- Installation verification
- Cleaning and flushing
- Calibration
- Rotation checks
- Alignment
- Control-loop testing
- Alarm and trip testing
- No-load testing
- Load testing
- Performance verification
- Operator training
- Documentation handover
Practical example
A new pump is checked for foundation condition, alignment, rotation, lubrication, instrumentation, pressure, flow, vibration, and protective-trip performance before formal handover.
Maintenance handover
Maintenance should receive:
- Asset data
- Drawings
- Manuals
- Spare-parts lists
- Warranty details
- PM recommendations
- Calibration records
- Baseline condition readings
- Training
- Final test results
Why baseline data matters
Initial vibration, temperature, current, and performance readings provide a reference for future condition monitoring.
Common mistake
Handing equipment to operations before asset records, spares, PM tasks, and documentation are ready creates long-term maintenance problems.
How this term differs
Commissioning is the broader process of preparing, testing, and placing equipment into service. It is related to Installation Qualification, Site Acceptance Test, and Performance Qualification, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.
