This course is intended to have a positive impact upon gas turbine operator decision-making. The course specifically targets Control Room Operators, wannabe CRO, and Shift Supervisors. Engineers can benefit as well.

A topical outline includes: Review of Gas Turbine Theory, Review of Gas Turbine Construction & Operating Principles, discussion of each of the 7FA Auxiliary Systems, Start Up Sequencing, Speed Control, Temperature Control, DLN2.6 Nox, Servo-Valve Drive Systems, Overspeed / Over Temperature, Protective Circuits, Abnormal Conditions and Response (this topic is actually covered throughout all the other presentations and is just summarized here).

WHAT YOU WILL RECEIVE:
  1. 1 copy of HPC Technical Services' textbook, Frame 7FA Gas Turbine Operations and Alarm Response, as written by Harold Parker. It is a valuable desktop reference in addition to being able to enhance the learning process.
  2. A "Certificate of Completion" with 2.9 CEUs, authorized for issue by the International Associate of Continuing Education/Training.
GAS TURBINE OPERATOR CERTIFICATION:
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.)

OBJECTIVES
Upon completion of this Seminar the participant should be able to:
  1. Describe the relationship of the various turbine components and how they may be at risk during operations.
  2. Describe the different fuel systems used in gas turbine operations.
  3. For each of the gas turbine auxiliary systems describe the systems' purpose, function of major components making up the system, normal operations, and abnormal conditions.
    1. Inlet and Exhaust Air
    2. Cooling and Sealing Air
    3. Lube Oil System
    4. Hydraulics
    5. Trip System
    6. Fuel Gas
    7. Liquid FuelFire Protection
    8. Water Wash
    9. Cooling Water
    10. Starting Means
  4. Given a gas turbine control system block diagram, sequence the turbine through start-up preparation, a start up, load changes, normal shutdown, and emergency conditions.
  5. Demonstrate the ability to navigate the operating screens to sufficiently to trace an alarm drop.
  6. Given an alarm, describe how the unit may be at risk.
  7. Given an alarm, describe what are the most proper actions to take (short- and long-term).
