Design/Project Engineering & Execution Phase
- Technical feasibility study, bid review, selection, specifications.
- Aerodynamics design appraisals.
- Rotordynamics design appraisals (lateral, torsional).
- Review of hardware design & construction drawings with OEM engineers/experts.
- Model testing/Campbell diagram of large diameter impeller.
- Blower/fan assembly inspection and shop testing.
- Electro-mechanical-aerodynamics control system design review.
- Design and off-design performance.
- Refurbishment/Upgrade studies.
- Installation & commissioning matters and performance examination during warrantee period.
Operational Phase
- Reliability & Mission time (extension studies).
- Performance gap/stretch studies.
- Blowers/Fans malfunctions diagnosis and cure (vibration, noise, pulsation, lube/seal oil, thermal signature, aerodynamic performance).
- Best practices of blower/fan condition monitoring, operation and maintenance.
- Condition-based inspection & maintenance schemes and decisions.
- 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.
- Estimation of system resistance curve.
- In-situ operating point on performance map (clean and fouled condition).
- Recycle and surge point optimization for parallel and series operation (as applicable).
- Blower/Fans fouling measurement schemes, evaluation and performance restoration.
- Actual flow measurements and calculation.
- On/off-lines condition monitoring schemes and performance package development (running power & efficiency estimation).
- Root cause investigation of distressed components, failure and restoration (impellers, shaft, bearings, seals, casing distortion).
- Rotor balancing (in-situ & shop balancing).
- Control systems problems.
- Review/improvement of blower/fan supervisory instrumentation.
- Alignment (hot/cold) and inlet/discharge ducts forces & moments.
- Life cycle cost & remaining life assessment.
