TG302 – Steam Turbine Generator Alignment

Description

On-Site Only Planning, scheduling, and implementing a steam turbine-generator 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 component will not disassemble according to procedure – what are your options?  Some component does not meet OEM specifications – what are your options?  Some component doesn’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 more with less time and money available.  This course is intended to help you (or your staff) make better steam turbine-generator maintenance decisions. Topical Outline includes: Planning, Scheduling and Decision Making; Maintenance of Shells, Casings & Rotors; Journal and Thrust Bearings; Couplings, SteamValves; Steam Path Alignment; Generator Maintenance; and Job Wrap Up. HPC Technical Services' course on Steam Turbine Generator Maintenance is, perhaps, one of the most popular courses we offer.  The course targets those individuals who have a need to better understand the maintenance process.  This includes engineers (who have not yet received formal training on this topic), experienced-mechanics, mechanical maintenance foremen, planners and management. Over the past couple years the most commonly received comment is, "I wish I had taken this course 10-years ago."  

Objectives

Upon completion of the course the participants should be able to:
  1. Describe the impact of various alignment problems on turbine efficiency and reliability.
  2. Determine the correct alignment for your turbine-generator.
  3. Describe the procedures for collecting and recording critical internal alignment data.
  4. Describe the process of evaluating the collected internal alignment data.
  5. Demonstrate an understanding on how to calculate and move internal stationary or rotating components to correct for misalignment.
  6. Describe the procedure for collecting and recording critical shaft alignment data.
  7. Describe the process of evaluating the collected shaft alignment data.
  8. Demonstrate an understanding on how to calculate and move shafts to correct for misalignment.
  9. Describe the advantages and disadvantages of the different alignment methods.

What you will receive

Steam Turbine Maintenance Certification

There are two levels of certification that require this course.:
  1. Steam Turbine Field Engineering Certification
  2. Steam Turbine Mechanical Maintenance Technician Certification
  3. Steam Turbine I&C Maintenance Technician Certification
Those who attend this course are automatically scheduled to take the HPC Technical Services' Certification Examination. This examination is scheduled as part of the course schedule and is offered at no additional expense to the participant. An 80% passing grade is required. The examination length will not exceed 2 hours. Those who complete this examination will receive a revised "certificate of completion" that recognizes this accomplishment along with a "To Whom It May Concern" letter that states their accomplishment.
