Centrifugal Compressor & Steam Turbine
Program Overview
Centrifugal compressors and steam turbines are critical rotating equipment in refineries, gas processing plants, petrochemical complexes and power and desalination plants, where an unplanned trip can stop an entire train. This course explains how they work and how to operate and maintain them reliably: compressor aerodynamics and performance curves, surge and anti-surge control, dry gas seals, bearings and rotor dynamics, steam turbine types, governing and overspeed protection, lube and seal oil systems, and machinery protection under API 670. Reference is made to API 617, API 611 and API 612 for design and testing, together with troubleshooting and condition monitoring practices.
Learning Outcomes
- ✓Interpret a centrifugal compressor performance map and locate the operating point relative to the surge line.
- ✓Explain the operation of an anti-surge control system and identify common causes of surge events.
- ✓Describe the function, support systems and failure modes of dry gas seals and journal and thrust bearings.
- ✓Compare steam turbine types and explain governing, extraction control and overspeed trip systems.
- ✓Diagnose typical vibration and performance problems in compressor and turbine trains.
- ✓Plan a start-up, shutdown and inspection sequence for a turbine-driven compressor train.
Target Audience
- Rotating equipment and machinery engineers
- Mechanical maintenance engineers and supervisors
- Operations engineers and senior operators of compressor trains

Training Methodology
Applied Project & Assessment
Applied Project
Participants analyse a compressor and steam turbine train from their plant or a case study, review its performance and protection data, identify the main reliability risks and propose operating and maintenance improvements.
Assessment
Short diagnostic at the start, practical tasks linked to each learning outcome, and evaluation of the applied project against published criteria.
