Course Description

GT Routine Maintenance - GT11, GT13E2, GT24, GT26

O-GAS20401

Course Description

This course familiarizes personnel with the architecture and function of the main parts, of the annular combustor engine.  Includes, maintenance overview, inspection preparation, EHS and O&M documentation, radial rotor position, EV burners and lances, tool handling and borescope.

This course is intended for personnel that are unfamiliar with or have limited knowledge of GE gas turbine maintenance.  For those who may work in affiliated industries and wish to gain an understanding of the routine maintenance requirements of GE heavy duty gas turbines.

Duration

5 Days

Learning Objectives

This course will provide basic knowledge on the following:

  • Understand the architecture and function of an annular combustor engine
  • State the purpose and the duration of the three types of inspection on the gas turbine (A, B, C)
  • Describe and carry out the required measurements before, during and after an A, B or C-inspection. (C-Inspection in summarizing form only)
  • Describe the correct use of the relevant documentation such as Test Certificates, Procedures and O&M Manuals
  • Select and correctly use of the relevant special tools, for performing the tasks required for an inspection
  • Perform in-situ Radial Rotor Position measurements, calculations and possible adjustments
  • Describe and apply the disassembly and re-assembly of:
    • EV Burners, EV and SEV Lances
    • Flame Monitors
    • Pulsation Probes EV and SEV, Ignition Probes

  • Describe the function of the installed Instrumentation
  • Perform an in-situ Borescope preparations and inspections
  • Apply all EHS procedures relevant to the task
