Release: 1

UEPOPS419 Shut down a steam turbine

Modification History

Release 1. This is the first release of this unit of competency in the UEP Generation Training Package.

Application

This unit involves the skills and knowledge required to conduct a shut down of a steam turbine to where it is placed at rest. Shut down of a steam turbine will involve the operator making a sequence of checks prior to and during shutdown. This ensures that the shut down of the turbine is completed in a safe and consistent manner. Competency in this unit requires the ability to plan and prepare steam turbine shut down, conduct a shut down, test steam turbine plant operation during shut down, analyse system faults during shut down and completing documentation. Individuals will, in general, work under supervision, in a power generation facility as an operator. Power generation plant operators are typically trained and authorised to isolate, prepare plant and issue 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 may require a licence or training permit to practice in the workplace where work is carried out on gas and electrical installations. Additional conditions may apply under state and territory legislative and regulatory licensing requirements.
