This unit involves the skills and knowledge required to install hydro turbines. The installation of a hydro turbine refers to a hydro turbine being removed from service, for repair and overhaul.

Installation is a key feature of placing hydro turbines into service, it can include conducting repairs and/or the overhaul of a hydro turbine to ensure reliability of operation during its service life.

Competency in this unit requires the ability to plan work, disassemble a hydro turbine, inspect hydro turbine's components, repair a hydro turbine and/or its' components and to report on all completed work tasks. Individuals will, in general, work under supervision 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 practice

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.
