Description

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 implementation of that plan.  This course is intended to improve the effectiveness of your combined cycle turbine maintenance activities.  Reduced number of forced outages and increased unit reliability and availability can be the result. We start by reviewing the basics.  One cannot implement an effective outage plan if one does not understand the fundamentals of how a combustion and steam turbine functions.  Learn how operating duty affects turbine components AND how the integrity of turbine components affects operations.  Learn important issues associated with disassembly / reassembly, in-situ inspections, and the differing type of inspections found on a gas turbine.  Equipment needs to be taken apart safely and properly.  Learn what components should be cleaned and how.  Learn the basics of a good visual inspection, use of in-situ inspection vehicles, and what mechanical / electrical tests might be performed. Topics include: Gas & Steam Turbine Construction • Outage Planning • Combustion / Hot Gas Path / Major Gas Turbine Outages • Major Disassembly Considerations • Inspection • Routine Repairs This course has been designed for plant personnel who are involved in safely and effectively operating and maintaining combined cycle plants.

Objectives

The overall objective is to increase participants’ capability to plan and implement future combined cycle turbine maintenance outages.  Upon completion of this course the participant will be able to:
  1. State the purpose of a combustion turbine and describe the major components that make up the combustion turbine.
  2. State the purpose of the steam turbine and describe the major components making up the steam turbine.
  3. Identify and state the purpose of those auxiliary systems associated with combined cycle turbines.
  4. Describe the sequencing that occurs in a normal startup, synchronization and operation.
  5. Describe the different fuel systems and requirements for operation.
  6. Demonstrate having the knowledge necessary to use effective and safe maintenance procedures.
  7. Demonstrate the ability to properly plan a maintenance outage prior to shutdown.
  8. Demonstrate the knowledge necessary to measure and interpret information as it relates to the unit outage.
  9. Demonstrate the knowledge necessary to disassemble/reassemble equipment in an orderly and safe manner.
  10. Demonstrate the knowledge necessary to properly clean and inspect combustion turbine components.
  11. Demonstrate the knowledge necessary to conduct non-destructive testing and automated inspections.

What You Will receive

  1. 1 copy of HPC Technical Services' textbook, CT204 Principles of Combined Cycle Turbine Maintenance. It is a valuable desktop reference in addition to being able to enhance the learning process.
  2. A Certificate of Completion

Gas Turbine Certification

There are two levels of certification (Both levels require this course):
  1. Field Engineer
  2. Maintenance Technician
Those who attend this course are automatically qualified to take HPC Technical Services' Certification Examination.  This examination 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 two-copies of a "To Whom It May Concern" letter that states their accomplishment.  (Two copies are provided, one for the participants' employer and one for the participants' personal file.)  Consult HPC's website, www.TurbineGeneratorTraining.com, for detail on this certification program.
