Design/Project Engineering & Execution Phase
- Technical feasibility study, bid review, selection, specifications.
- Steam path design appraisals.
- Rotordynamics design appraisals (lateral, torsional).
- Model testing/Campbell diagram of blades, bladed-disc.
- Review of hardware design & construction drawings with OEM engineers/experts.
- Electro-mechanical-steam control system design review.
- Turbine assembly inspection and shop testing.
- Design and off-design performance.
- Refurbishment/upgrade studies.
- Installation & commissioning matters and performance examination during warranty period.
Operational Phase
- Reliability & Mission time (extension studies).
- Performance gap/stretch studies.
- Steam turbines malfunctions diagnosis and cure (vibration, noise, pulsation/acoustic, lube oil, sealing steam, thermal signature, aerodynamic performance etc.).
- Best practices of steam turbines 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.
- Root cause investigation of distressed components, failure and restoration (blade, bladed-disc, bearings, seals, casing distortion, barring connection etc.).
- Rotor balancing (high speed & low speed).
- Actual steam flow measurement and calculation.
- Turbine fouling monitoring and evaluation.
- Vacuum and side streams malfunction study.
- Governing and control systems problems.
- Thermal expansion of rotor-stator interaction during start up.
- Review/improvement of turbine supervisory instrumentation.
- On/off-lines condition monitoring schemes and performance package development (condensing turbines last rows blade operational dynamics, power & efficiency estimation).
- Alignment (hot/cold) and piping forces & moments.
- Life cycle cost & remaining life assessment.
