Course Description:

Gas turbines became widely adopted and many thousands of sets are now installed worldwide. The development of gas turbine from the theoretical stage to its present worldwide adoption has three main inputs.

The increase in the size and complexity of gas turbines has resulted in maintenance being accepted as an important mainstream function in such companies.

This course provides the participants with the means to properly operate and support the gas turbines in a way based on the good acquaintance with the modern technologies applied in this field. Trouble-shooting & forecasting break downs are inclusive

Course Goal:

To enhance the participant’s knowledge, skills, and abilities necessary to give him some practical exposures to help maintain the gas turbines in good operational conditions and cope with the emergency cases of breakdown
