This unit involves the skills and knowledge required to isolate, disconnect, repair, reconnect and undertake maintenance of stationary gas fuelled reciprocating engines. It does not include repairs to the internal mechanical components of the engine.

Maintenance includes the regular monitoring, inspection and verification of the safe and efficient operation of a power generation facility's stationary gas fuelled reciprocating engine.

Competency in this unit requires the ability to work safely to relevant industry standards when disconnecting, carrying out repairs and replacing fuel train components to given specifications. It also includes reconnecting the engine including pre-start tests, start-up, adjusting components and controls for safe and efficient operation and completing all required documentation. Individuals will, in general, work as a maintenance operative, in a power generation facility.

Power generation maintenance personnel are typically trained and authorised to receive permits to work.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Note: Workplace practices

The application of the skills and knowledge described in this unit of competency may require a licence or training permit to practice in the workplace, where work is carried out on gas and electrical installations. Additional and/or other conditions may apply under state and territory legislative and regulatory licensing requirements.
