Gas Turbine Operations (Generic)

Gas Turbine Operations (Generic) (Ref:OTSGTO001)

Gas Turbine Operations (Simulation Based)

Course Ref: OTSGTO001
Course Duration: 5 Days

Course Description:

This course covers the operations of a Gas Turbine. The course will introduce the student to the Major Components of a Gas Turbine and associated systems. Operational sequences will be discussed for the major varieties of Gas Turbines, including startup, synchronising and loading. The use of a Gas Turbine simulator will allow students to view various operational problems and introduce the concepts of basic troubleshooting and fault finding.

?Who should attend:

This is an excellent course for plant operators/technicians responsible for the day-to-day operations of a Gas Turbine. The course will also benefit maintenance personnel who are involved in the troubleshooting of operational problems. Shift supervisors and Team Leaders will also find the course beneficial.
