Machine context
Review rotor and bearing arrangement, driver and coupling, foundation, piping, lubrication, instrumentation, process duty and recent maintenance.
Expertise 04
Rotating Equipment
Machine-level assessment that connects design, operating duty, dynamic behaviour and maintenance condition across turbines, compressors, pumps, gearboxes, fans and associated systems.
Working principleUnderstand the machine before interpreting the signal; the same spectral feature can have different meanings across designs and operating states.
Scope of practice
What the work focuses on.
Mechanical behaviour
Assess speed-related response, alignment, balance, looseness, resonance, bearing condition, gear interaction, fluid forces and structural influence.
Maintenance verification
Support test runs, response testing, balancing and post-maintenance checks with defined acceptance evidence and traceable findings.
Evidence-led workflow
A disciplined path from question to verified action.
Each stage protects the quality of the conclusion. A technically correct measurement can still lead to a poor decision when operating context, machine design or maintenance history is ignored.
- 01Establish configuration
Confirm equipment type, train arrangement, bearings, operating range, instrumentation and relevant OEM requirements.
- 02Review operating and maintenance state
Capture speed, load, process conditions, starts, trips, work history and known defects.
- 03Observe the machine response
Combine dynamic measurements, visual inspection, process data and mechanical checks appropriate to the symptom.
- 04Separate cause from symptom
Test whether the evidence supports mechanical, structural, hydraulic, aerodynamic, electrical or process-driven mechanisms.
- 05Verify equipment outcome
Confirm the effect of corrective work against the intended mechanical and operational result.
Standards foundation
Guidance before assumption.
These references establish the public technical foundation. The applicable machine-specific standard, OEM manual and site procedure always take priority for a real assessment.
