The course combines good overall operational practices with specifics of the Mk-IV control system. The Mk-IV portion of the course is adjusted to specifically deal with level required by Operations personnel. To operate a machine safely and for the long-term, we need to have a good understanding of the basic theory, we need to know how different components might be placed at risk, we need to understand how the Mk-IV control system “thinks”, how the Mk-IV system files are utilized to an operators advantage, we need to know how and when the protective systems should react, and we need to know the importance of proper operation of the auxiliary systems. With respect to the protective systems, we need to understand the symptoms of some of the common problems, what actions the operator should (or should not) take, what actions protective systems should take, and when. This course discusses all of this in a generic fashion (that is not necessary specific to any given machine). A good big-picture is required to become a “skilled operator” and this course takes us down that path.

A topical outline includes: Review of Gas Turbine Theory, Review of Gas Turbine Construction & Operating Principles, Intoduction to Mk-IV Hardware, Documentation, How to Read Mk-IV Elementaries, Auxiliary Systems, Start Up Sequencing, Speed Control, Temperature Control, NOx, Servo Valve Drive Systems, Overspeed / Over Temperature, Protective Circuits, Abnormal Conditions and Response.

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. Identify and describe the purpose of major hardware devices found in the Mk-IV system.
  4. Demonstrate the ability to use that Mk-V Documentation that is pertinent to the operator.
  5. Demonstrate the ability to navigate the Mk-IV elementaries to trace an alarm to the device initiating that alarm.
  6. For each of the gas turbine auxiliary systems (cooling & sealing air, lube oil systems, fuel forwarding, control and hydraulic oil) describe the systems' purpose, normal operations, and abnormal conditions.
  7. Given a gas turbine control system block diagram, sequence the turbine through a start up, load changes, shutdown, and emergency conditions.
  8. Demonstrate the ability to navigate the Mk-IV elementaries sufficiently to trace an alarm drop to the initiating algroithym.
  9. Given an alarm, describe how the unit may be at risk.
  10. Given an alarm, describe what are the most proper actions to take.
