Release 1 . This is the first release of this unit of competency in the UEG Gas Industry Training Package.

This unit involves the skills and knowledge required to isolate, disconnect, repair, reconnect and maintain stationary gas fuelled turbine engines up to a capacity of 5 gigajoule per hour (GJ/hr) (1,300 kilowatt).

It includes disconnecting, carrying out repairs and replacing fuel train components to stationary gas fuelled turbine engine. Reconnecting the gas fuelled turbine engine includes pre-start tests, start up, adjusting components and controls to safe and efficient operation, and completing all required documentation.

This unit does not cover:

• repairs to the internal mechanical components of the engine
• modifications to gas fuelled turbine engine.

Note: 500 kw equates to a gas input of approximately 6 GJ/hr.

The application of the skills and knowledge described in this unit may require a license or permit to practice in the workplace.

Other conditions may apply under state and territory legislative and regulatory licensing requirements which must be confirmed prior to commencing this unit.

Not applicable.
