6. Conduct pre-start checks. This typically include checking:
cooling water supply
overspeed trip
emergency stop
operation and position of valves, fittings, steam traps and steam line purge systems
lubrication system
drainage system

heat input
free rotation of turbine
reticulation line pressure and system warm up
7. Liaise with other work areas to advise of turbine status
8. Demonstrate set up and start up procedures in both manual and automatic modes and for both a hot start and cold start
9. Monitor turbine operation. This typically includes monitoring:
bearing temperature
pressures
speeds
glands
water filters
oil levels
equipment condition including noise and vibration
steam reticulation line pressure
lubrication system
condenser operation (where fitted)
10. Take corrective action in response to abnormal or unacceptable performance
11. Report and/or record corrective action as required
12. Demonstrate shift handover procedure and confirm that replacement operators are aware of equipment status and operating requirements prior to completing handover
13. Demonstrate procedure to take turbine off line
14. Demonstrate procedure to prepare the turbine for a prolonged shut down. This includes removal of valves and fittings
15. Demonstrate emergency trip procedure and related re-start
16. Record operating information
17. Maintain work area to meet housekeeping standards
May include ability to:
18. Use process control systems
Knowledge of:
19. Relevant state OHS legislation, standards and codes of practice relating to work responsibilities
20. Safety features of the turbines. These include relief and over-speed trip valves
21. Safe work procedures including awareness of health and safety hazards related to turbine operation and associated control measures. Hazards typically include handling chemicals, working around hot surfaces, working around moving equipment, manual handling, fuel and steam leaks.
22. Hierarchy of hazard control measures
23. Duty of care of the turbine operator
24. Purpose and limitations of protective clothing and equipment
25. Purpose and basic principles of turbines. This includes properties of steam
26. Turbine system layout and steam cycle
27. Relationship to other processes. This includes suppliers and users of steam across the site
28. The effect of steam quality on turbine operation
29. The effect of low steam pressure on turbine operation
30. Methods used to render equipment safe to inspect, maintain and/or clean including lock-out, tag-out and isolation procedures
31. Equipment purpose and basic operating principles of turbine and related equipment
32. Operating requirements and parameters
33. Procedures for responding to emergency situations. This includes safe operational shutdown procedure
34. Handover and long term shut down and storage procedures
35. Environmental issues and controls
36. Housekeeping standards for the work area
37. Reporting and recording systems. This includes both statutory and workplace requirements
May include knowledge of:
38. Basic operating principles of process control where relevant. This includes the relationship between control panels and systems and the physical equipment
Relationship with other standards
Pre-requisite units
There are no pre-requisite units for this competency standard.
Co-assessment of related units
Other units of competency relevant to the work role should be assessed in conjunction with this unit. This may include:
SUGZPCI2A Operate a process control interface
Resources required for assessment
Assessment must occur in a real or simulated workplace where the assessee has access to:
Turbine and related equipment
Relevant codes and standards
Operating procedures and related advice on equipment operation
Personal protective clothing and equipment
Communication systems and equipment
Housekeeping standards and procedures
Workplace information recording systems, requirements and procedures
Assessment requirements
For assessment advice where the turbine operation is not a certified occupation, refer to the Assessment Guidelines for this Training Package. Where turbine operation is a certificated occupation, refer to the appropriate NOHSC competency standards, available from National Occupational Health and Safety Commission.
