COURSE OVERVIEW

This practical and highly-interactive course includes various practical sessions and exercises. Theory learnt will be applied using our state-of-the-art simulators. 

 

This course is designed to provide participants with a detailed and up-to-date overview of Heavy Duty Gas Turbine Major Inspections. It covers the fundamentals, components, operation principles and types of gas turbine; the different level of maintenance including PM, CM & PDM; the safety standards, personal protective equipment (PPE) and procedures for site preparation; the specialized tools and equipment used during major inspections; the OEM (original equipment manufacturer) and OMM (operation and maintenance manual); the purpose, frequency and scope of major inspections and others like limits of DR according to GE standard; and the replacement of selected external components including variable geometry actuators, control unit, VG pump, VBV doors and rigging of system if applicable. 

 

Further, the course will also discuss the replacement of lubrication and scavenge pump, pressure and temperature sensors, fuel nozzles and vibration accelerometers; the replacement of ignition components, starter, speed sensors, carbon seals, and external pipes and hoses; the removal of low- and high-pressure turbine, stage 1 nozzle module, combustor module and bearing inner race; the stage 2 high pressure turbine nozzle replacement as well as the installation of stage 1 nozzle module and high-pressure and low-pressure turbine module; and the removable of variable inlet guide vane (VIGV), stage 0 blade replacement, removable and installation of LP compressor and replacement of #1 air/oil seal. 

 

During this interactive course, participants will learn the LP compressor stage 1-3 blade replacement and LP compressor stage 0-3 vane replacement; the auxiliary gear box check and techniques for ensuring proper alignment; the calibration of turbine components; the steps for safely commissioning and turbine post-inspection; the performance tests to verify turbine functionality; and the techniques for analyzing turbine vibrations to identify issues.
