Gas Turbine Driven Centrifugal Compressors

Course Content

Aim

This site-specific course is designed to enable engineers, supervisors, operations, and maintenance personnel to safely operate GE designed heavy duty gas turbine units.  This course develops a background in gas turbine operation that will enable participants to properly analyse operating problems and take the necessary corrective action.

Emphasis is placed on the operator’s responsibilities with regard to auxiliary systems, operational data taking, and data evaluation. Operators are instructed in how to interpret fault annunciation and how to determine if the annunciated fault can be remedied by operator action or by the assistance of instrumentation and/or maintenance personnel. The course focuses on the starting, loading, and specific operator checks of the various turbine support and auxiliary systems to ensure safe and reliable operation of the gas turbine unit. Also covered is the effect of operation on major mechanical maintenance.
