This course will 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 course offers a firm understanding of the basic operations of all types of gas turbines. 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. The course does not include any discussions of generators.

By the end of this course delegates will learn about:

· Basic gas turbine operating cycle, Operating parameters and control

· Overview of gas turbine major components and equipment arrangements

· Fundamentals of gas turbine control and protection: start-up, speed, load, shutdown and temperature

· 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

· Engine nomenclature & functions, Engine systems operation

· Gas turbine principles and theory, Troubleshooting techniques through class discussions
