CT325 – Frame 5 Gas Turbine Operations & Alarm Response

CT325 – Frame 5 Gas Turbine Operations & Alarm Response

4.5 days - 32 PDH Credits Awarded



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 outlineincludes:  Review of Gas Turbine Theory, Review of Gas Turbine Construction & Operating Principles, discussion of each of the Frame 5 Auxiliary Systems, Start Up Sequencing, Speed Control, Temperature Control, DLN1 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).

HPC’s 3-4-2 policy applies:  Sign up 3 for the same course/date, pay in advance, and pay for only 2 (the 3rd participant is free)! HPC Technical Services reserves the right to cancel any course/seminar within 10-working days of the scheduled date.  Fees are 100% refunded or credited to another Seminar (clients' choice) if HPC should cancel any Seminar.  HPC is not responsible for non-refundable airline tickets or other travel expenses under any circumstance.

What you will receive

  1. 1 copy of HPC Technical Services' textbook, Frame 5Gas Turbine Operations and Alarm Response, as written by Harold Parker with technical support from Sal Paolucci.  It is a valuable desktop reference in addition to being able to enhance the learning process.
  2. A Certificate of Completion with 31 PDH.

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.) Consult HPC's website, www.TurbineGeneratorTraining.com, for detail on this certification program.


All HPC instructors are educated ‘experts’ on the subjects they teach, with years of relevant hands-on experience (typically 20+ years), and have proven instructional skills. Brief resumes can be looked up on HPC’s website, www.TurbineGeneratorTraining.com.


Upon completion of this course, the participant will 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. Trip System
    5. Fuel Gas
    6. Liquid Fuel
    7. Fire 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).
