  1. Safety is objective #1.  Learn the safety precautions that must be adhered to, during a turbine-generator overhaul.
  2. Planning is critical to success.  Learn those parts of planning that are peculiar to turbine-generator outages, such that success can be achieved.
  3. Proper disassembly -reassembly techniques can make or break your outage schedule.  Learn those techniques that are used by experienced service engineers who are responsible for overall outage management.
  4. Proper use of non-destructive testing gives you valuable information regarding what needs to be done during the outage (even when it causes a change in plans).  Learn what should be tested, how, and when.
  5. Learn the 5 most common causes of steam path damage and considerations to be made regarding the repair/replace/reuse of affected components.
  6. Improper bearing design/assembly/alignment will cost you valuable outage time when it comes to re-start.  Avoid issues such as these by understanding the common causes of bearing damage and how to avoid or correct.
  7. When cleaning there are some procedures/compounds you should use and some procedures/components you should not use.  Learn to make the right decisions.
  8. Learn proper maintenance activities for the TG auxiliary systems.
  9. Learn the various repair methods that are used to correct defective component condition.
  10. Learn to properly evaluate alignment of turbine-generator components, and realign if necessary.
  11. Learn visually inspect generator components with an eye toward those most common signs of distress.
  12. Learn the value and purpose of conducting electrical tests on generator components.

Remember, HPC Technical Services conducts this training to help its clients accomplish their goals, whether it is independence or just to be able to ask better questions of the OEM assigned technical advisor and expect better answers.  Unlike some of our competition, HPC does not provide engineering services as our primary business venture.  Therefore, it is not our purpose to sell these other engineering services.

HPC Technical Services's instructors, each have 30+ years experience, and HPC has several different instructors that may be employed for any particular Seminar presentation.    We conservatively estimate that 1000+ persons have benefited from HPC instruction on this subject alone!  Sign up today and see why this Seminar, this year, is more popular than ever with our recent Seminar reorganization.


  1. Monday
    1. Planning, Scheduling and Decision Making:  This presentation is intended to provide participants with an understanding of those major items that must be considered PRIOR to commencing a scheduled turbine-generator outage.  Discussion will also include those items we need to consider when making repair/replace/reuse decisions.
    2. Turbine Shells, Casings & Rotors:  This lecture is intended to prepare the participant to safely and efficiently disassemble/reassemble major turbine components, as well as to improve inspection/repair techniques, communications on equipment, and make better replace/repair/reuse decisions.  Presentations include specific discussions on the different types of distress typically found on these components.
  2. Tuesday
    1. Turbine Shells, Casings & Rotors: continues for ½ day.
    2. Journal & Thrust Bearings:  Learn the different types of bearings and their applications, disassembly/reassembly procedures, inspection techniques, and typical types of distress as well as causes.
    3. Couplings:  Learn what types of couplings are used on T-G sets, how torque is transferred, how to properly disassemble/reassemble, how to inspect, what measurements to take, and what they mean.
  3. Wednesday
    1. Steam Valve Maintenance:  Learn the purpose of the various steam turbine valves, how to properly disassemble/reassemble, how to inspect, what are the typical types of distress, what measurements to take, and what they mean.  Valves include Main Stop Valve, Main Control, and Extraction Control Valves.
    2. Generator Maintenance:  Learn how a large AC generator is constructed, how to disassemble major components, what are the typical types of distress, how to clean, routine repair, and why generator inspection/testing is so important.  This presentation also includes an introduction to the various electrical test techniques.
  4. Thursday
    1. Auxiliary Systems:  Presentations include the Turbine Lube Oil Systems, Steam Seal Systems, Hydraulic Power Unit, Generator Seal Oil Systems, and Hydrogen Systems; Discussions include Operations, Preventive Maintenance, Alarm Response, and Outage Maintenance Activities.
    2. Alignment:  Learn how to properly take clearance/alignment data and how to evaluate.  Discussions include how to calculate and make moves for stationary equipment such as diaphragms and inner shells.  Discussions also include how to take coupling rim/face readings, how to calculate moves to correct for coupling misalignment, and how to calculate and make moves to bearings to accomplish alignment objectives.
  5. Friday
    1. Alignment Continues
    2. Job Wrap-Up:  Learn what kind of data should be recorded following the outage, and what checks to make as we prepare to return the equipment to service.

What you will receive:

  1. One copy of HPC,s textbook, Extraction Steam Turbine Generator Maintenance, as written by Harold Parker, with technical support by Robert Doughty, Turbine Services Incorporated, and Doug Lemmo. 
  2. A "Certificate of Completion" with 2.9 Continuing Education Units.

For those who volunteer to be members of HPC's Steam Turbine Field Engineering Certification Program, they will receive one comprehensive examination that is to be completed and returned to HPC under specific guidelines for that program.  That participant will receive further accommodation for his/her accomplishment.  This examination is at no additional cost.
