vCT563 – Principles Of a Frame 7F Major Inspection

4 days (4-hours sessions) - 16 PDH Credits Awarded


No future dates scheduled


In today’s environment it is important to be properly prepared for turbine outages.  Even if you are not expected to be the “technical advisor”, it is still important for you to appreciate all the activities that are important to the outage plan and its implementation.  This course is intended to improve the effectiveness of your Frame 7FA major inspection activities.

Topics include: Outage Plan, Accessibility, Compressor Disassembly, Rotor Removal, Inspection of Compressor Rotor and Stator, Reassembly and Alignment.

This course has been designed for plant personnel who are involved in safely and effectively maintaining combustion turbines. The course assumes the  participant has an understanding of the function and construction of those combustion turbine components to be inspected as well as those activities performed during a combustion and a hot gas path inspection.  If not, we suggest participating in our Combustion Turbine Fundamentals (vCT201) class and our “Principles of a Frame 7F Combustion Inspection” class (CT561), and our Principles of a 7F Hot Gas Path Inspection classes prior to participation in this session.


  1. List the gas turbine operational and safety issues that typically cause the scheduling of a maintenance outage.
  2. Describe the purpose and conceptual differences of a combustion, hot-gas-path, and major inspection.
  3. Demonstrate sufficient knowledge to conduct a major inspection.
  4. List the considerations that are to be included when developing an outage plan or schedule.
  5. Describe the major considerations when making repair/replace/reuse decisions.
  6. Describe the procedures for the safe and effective disassembly/reassembly of the gas turbine components associated with a major inspection.
  7. Describe the type and purpose of clearance and alignment measurements commonly taken during the disassembly and reassembly of the gas turbine unit.
  8. List and describe the various non-destructive examinations that are performed during disassembly of the gas turbine.
  9. Describe the common procedures for cleaning and inspecting gas turbine components.
  10. Describe the common repair methods for gas turbine components.
  11. Describe the methods used to properly align gas turbine-generator components.

Virtual instructor led training (VILT) schedule on vC562 is for three ½-day classes and is often scheduled to immediately follow vCT561, a Frame 7F Combustion Inspection.  Enrollment should be 10-days in advance of the scheduled dates to allow HPC to forward copies of the text prior to course beginning.

HPC Technical Services reserves the right to cancel any course/seminar within 10-working days of the scheduled date.  Fees are 100% refunded or credited to another Seminar (clients' choice) if HPC should cancel any Seminar.
