Mark V Operator

Course Objective

The Operator course is designed for Operators, Supervisors and Technicians involved in the Operation of gas turbines with the subject Turbine Control Panel (TCP). One of the fundamental objectives of the course is to teach the basic knowledge to identify and determine the cause of process and diagnostic alarms in the TCP. During the course, we will also discuss gas turbine fundamentals, main auxiliary systems, introduction to: gas turbine protection, TCP hardware, etc.
The course provides the fundamental tools to operate the Gas Turbine utilizing the TCP, and an introduction to theoretical aspects to further the self-learning process.
