Maintenance EngineeringIntroduction
Gas Turbine Training classes provide technical information for those people who maintain the gas turbine engines. The goal of each training program is to build confidence based on knowledge and understanding. Engine System Familiarization and Maintenance Procedures are key focal points of each program. This training is built on a foundation that will enable the student to understand:
Objective
The objective of this course is to give participants an understanding of basic gas turbine operations and construction as well as a fundamental knowledge of proper operation, control and protection of the turbine and its accessory systems.
Emphasis is placed on the following areas:
· Basic gas turbine operating cycle
· Overview of gas turbine major components and equipment arrangements and how these relate to overall operation and performance
· Fundamentals of gas turbine control and protection: start-up, speed, load, shutdown and temperature
· Operating parameters and control / protection features of the various turbine support systems such as the lubricating oil, hydraulic, variable inlet guide vanes, starting means and fuels
· Operating factors and considerations that affect maintenance intervals
Audience
Operators, engineers, technicians, and administrative personnel of operating facilities as well those who may work in affiliated industries, who wish to gain an understanding of the day-to-day operation of heavy duty gas turbines.

Methodology
Our courses are highly interactive, typically taking a case study approach that we have found to be an effective method of fostering discussions and transferring knowledge. Participants will learn by active participation during the program through the use of individual exercises, questionnaires, team exercises, training videos and discussions of “real life” issues in their organizations.
The material has been designed to enable delegates to apply all of the material with immediate effect back in the workplace.
