Course Description

GT Frame 5 Maintenance & Inspection

Course Objectives:

  • The objective of this course is to familiarize the trainees with the fundamentals of gas turbines. To explain the functions and principles of operation of each of the major components and systems of the package. To introduce standard operating procedures for the package, and describe basic maintenance, inspection and troubleshooting techniques.Design parameters, performance, data sheets, alarm and set points, PIDs, …etc will be delivered.
  • The course explains how turbines works and the different types in common use. How to control and operate Turbines efficiently and key troubleshooting techniques and information will also be explained.
  • This course aimed to enhance the technical knowledge of the operation and maintenance staff to built confidence level in start-up, follow-up, shut down and trouble shooting.
  • This course focuses on defining the systems and subsystems that form the turbine, the potential problems with these systems and subsystems, monitoring techniques for early detection of problems, and methods to analyze the monitored variables to detect potential problems or reconstruct reasons for failures. Case studies are used throughout the course.
  • Maintenance program and inspection procedures will be covered to improve trainees’ skills in executing activities in safe and right manner.
