Elements and Performance Criteria
- Prepare for work
- Start the gas turbine
- Check that the turbine is not subject to maintenance or that other permitted activities are not taking place near the equipment
- Check the control panel to ensure that all indications support the safe starting of the turbine
- Conduct required safety checks and pre-starts to determine or verify the operational condition of the equipment
- Commission turbine protection devices prior to the start-up of equipment
- Achieve operational flows and temperatures of ancillary equipment before bringing the system on line for use
- Start the gas turbine according to procedures
- Monitor and assess gas turbine systems
- Complete routine checks, logs and paperwork taking action on unexpected readings
- Change rate, smoothly as required
- Monitor and correct fuel and energy systems and flows to ensure that the system provides the proper operational mixture for turbine use
- Ensure adequate supplies of clean air at the stated rate or temperature are delivered to the turbine to allow for successful operation to be achieved
- Check exhaust gas and turbine operating temperatures to ensure correct temperature gradients in the turbine
- Monitor lubrication systems to verify that operational parts are functioning efficiently and effectively, and to ensure that all moving parts are operating in a friction free and clean environment
- Monitor and adjust cooling systems to allow for the most efficient operating temperature to be maintained throughout all operating conditions
- Monitor governing systems to allow correct operational speeds of equipment to be maintained and regulated
- Adjust turbine and its component plant items as appropriate to their type and duty to maximise performance
- Check maintenance requirements
- Conduct routine inspections and checks to ensure normal or stated turbine operation is maintained
- Identify equipment faults through observation of the operational equipment and periodic sampling and testing
- Determine action and communicate maintenance requirements to appropriate personnel
- Record operational data to provide a historical record of the operating condition of equipment
- Respond to gas turbine problems
- Monitor turbine and its component plant items frequently and critically throughout shift using measured/indicated data and senses
- Describe impacts of any changes upstream and downstream
- Recognise actual and developing situations which may require action
- Apply operational knowledge to resolve problems
- Take other appropriate actions on abnormal situations which cannot be resolved during the shift to ensure safety and the resolution of the situation
- Follow through items initiated until final resolution has occurred
- Isolate and de-isolate turbine and its component plant items
- Shut down turbine according to the turbine type and duty in liaison with other personnel
- Shut down/changeover component plant items within unit according to their type and duty in liaison with other personnel
- Isolate entire turbine system and/or any component plant item
- Make safe for required work
- Check turbine/plant item is ready to be returned to service
- De-isolate and prepare turbine/plant unit/plant item for return to service
