Course Objectives

The primary function of this course is to allow the attendee a detailed understanding of the applications, operations and maintenance of Gas Turbines.

Course Description

The use of Gas Turbines in the Power Generation, Petrochemical and Pipeline Industries has increased considerably in the last few years. The development, in particular, of Combined Cycle and Combined Heat and Power applications has accelerated the use of Industrial Gas Turbines. This course will cover the design, operation and maintenance of the various types of Gas Turbine and Gas Turbine applications. Advances in Gas Turbine Technology will also be discussed with focus being on latest machine types and emission control technology. Presenting this course at our facility will allow attendees to see practical examples of Gas Turbine Components, types of component faults and associated repair techniques.

Who Should Attend

This course is targeted at technicians and engineers involved in the operation and maintenance of Gas Turbines. Experienced engineers and maintenance specialists will also benefit from attending this course as will those managers concerned with the maintenance scheduling and repair aspects of Gas Turbines.

Pre-requisites

All trainees should have a sound Power Generation background.

Course Outcome

At the end of this course you will be able to understand the applications, operations and maintenance of a gas turbine.
