Design/Project Engineering & Execution Phase

1. Technical feasibility study, bid review, selection, specifications.
2. Aerodynamics design appraisals.
3. Rotordynamics design appraisals (lateral, torsional).
4. Review of hardware design & construction drawings with OEM engineers/experts.
5. Model testing/Campbell diagram of large diameter impeller.
6. Blower/fan assembly inspection and shop testing.
7. Electro-mechanical-aerodynamics control system design review.
8. Design and off-design performance.
9. Refurbishment/Upgrade studies.
10. Installation & commissioning matters and performance examination during warrantee period.

Operational Phase

1. Reliability & Mission time (extension studies).
2. Performance gap/stretch studies.
3. Blowers/Fans malfunctions diagnosis and cure (vibration, noise, pulsation, lube/seal oil, thermal signature, aerodynamic performance).
4. Best practices of blower/fan condition monitoring, operation and maintenance.
5. Condition-based inspection & maintenance schemes and decisions.
6. Pro-active performance appraisals of key parameters during steady state/transient modes to capture faults at embryonic stage before they turn in to full-scale problem that may lead to un-plan interruption in production.
7. Estimation of system resistance curve.
8. In-situ operating point on performance map (clean and fouled condition).
9. Recycle and surge point optimization for parallel and series operation (as applicable).
10. Blower/Fans fouling measurement schemes, evaluation and performance restoration.
11. Actual flow measurements and calculation.
12. On/off-lines condition monitoring schemes and performance package development (running power & efficiency estimation).
13. Root cause investigation of distressed components, failure and restoration (impellers, shaft, bearings, seals, casing distortion).
14. Rotor balancing (in-situ & shop balancing).
15. Control systems problems.
16. Review/improvement of blower/fan supervisory instrumentation.
17. Alignment (hot/cold) and inlet/discharge ducts forces & moments.
18. Life cycle cost & remaining life assessment.
