Description
This unit involves the skills and knowledge required to conduct a shutdown of a steam turbine to where it is placed at rest.Shutdown of a steam turbine will involve the operator making a sequence of checks prior to and during shutdown. This ensures that the shutdown of the turbine is completed in a safe and consistent manner.Competency in this unit requires the ability to plan and prepare steam turbine shutdown, conduct a shutdown, test steam turbine plant operation during shutdown, analyse system faults during shutdown and complete documentation. Individuals will, in general, work under supervision, in a power generation facility as an operator.Power generation plant operators are 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.
