Description

Planning, scheduling, and implementing a steam turbine outage can be one of the most demanding tasks you perform.  Especially, when problems are found that were not anticipated (and there are always these kinds of problems).  In the class we will learn to better plan the work (from a technical perspective).  Once the work is planned, as we know, the next task is to work the plan.  Here is where the surprises can occur.  Some components will not disassemble according to procedure – what are your options?  Some components do not meet OEM specifications – what are your options?  Some components don’t go back together according to procedure – again, what are your options?  These options usually involve repair / replace / reuse decision making.  Effective decision making is a function of your knowledge of the importance of this component, your understanding of recommended tolerances, your understanding of how different options can impact the schedule and/or cost of this outage.  Complicating this issue is a strong need to make outages shorter in length, AND longer in frequencies between outage.  It’s simple:  You need to do more with less time and money available.  This course is intended to help you (or your staff) make better steam turbine maintenance decisions. Over the past couple years the most commonly received comment for our traditional steam turbine maintenance training was, "I wish I had taken this course 10-years ago."  Well, we’re planning on the same comments for the VILT (virtual instructor led training) sessions.

Objectives

Upon completion of the course the participants should be able to:
  1. List steam turbine operational and safety issues that typically cause the scheduling of a maintenance outage.
  2. List the considerations that must be included when developing an outage plan or schedule.
  3. Describe the major considerations when making a replace/reuse/repair decision.
  4. Describe the procedures necessary for the safe and effective disassembly and reassembly of steam turbine components.
  5. Describe the purpose and operation of the major steam valves.
  6. Describe the disassembly and reassembly of the major steam valves.
  7. List the five (5) most common causes of steam path damage and their possible affects upon future operation.
  8. Describe three (3) common causes of steam path defects and their impact upon turbine efficiency and reliability.
  9. Describe the type and purpose of clearance and alignment measurements commonly taken during the disassembly and reassembly of a steam turbine.
  10. Describe the measuring instruments used to determine steam turbine component clearances.
  11. List and describe the various non-destructive examinations performed during disassembly of the steam turbine.
  12. Describe the common procedures for cleaning and inspecting steam turbine components.
  13. Describe the criteria used to evaluate steam turbine defects.
  14. Describe the common repair methods for repair of steam turbine components.
  15. Describe the purpose of conducting a steam path audit, and how that audit would be accomplished.
  16. Describe the common types and operation of journal and thrust bearings.
  17. Describe the common causes of bearing damage.
  18. Describe the measurements required to determine oil clearances.
  19. Describe common bearing inspection and repair procedures.
  20. Describe the considerations to be taken into account when evaluating alignment of steam turbine components.
  21. Describe the methods used to properly align steam turbine components.
  22. Demonstrate the ability to perform the necessary calculations to align steam turbine components.
