Description
This unit of competency covers the skills and knowledge required to operate and maintain a complex refrigeration/cryogenic system.This unit of competency includes all such items of equipment and unit operations which form part of the complex refrigeration/cryogenic system. A unit/system comprises two or more components of plant/equipment that are operated together to produce product, including as appropriate to the facility:large refrigeration systems that produce low temperatures multi-stage centrifugal compressorsheat exchangers computer controlmonitoring systems.This unit of competency applies to operations technicians who are required to demonstrate a significant understanding of the process and the equipment operation in order to identify and rectify operational problems, perform isolations, start-up and shutdown procedures, and operate, monitor and maintain equipment.This unit of competency applies to an individual operating independently in a plant with local control or in liaison with the control room operator in a plant with a centralised control panel, such as distributed control system (DCS) type controls. In the case of large complex plant, the operations technician would be part of a team during start-up and shutdown procedures. This unit of competency applies to an individual working alone or as part of a team or group and working in liaison with other shift team members and the control room operator, as appropriate.This competency does not require the operation of a central control panel. No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1 Prepare for work
  • 1.1 Receive and give shift handover
  • 1.2 Identify work requirements
  • 1.3 Identify and control hazards
  • 1.4 Coordinate with appropriate personnel
  • 1.5 Check for recent work undertaken on cryogenic process
  • 1.6 Note any outstanding/incomplete work
  • 1.7 Check operational status of cryogenic process
2 Operate cryogenic process
  • 2.1 Describe the type of cryogenic plant, the component plant items and their duties
  • 2.2 Complete routine checks, logs and paperwork taking action on unexpected readings
  • 2.3 Change rate, grade or specification smoothly as required
  • 2.4 Adjust cryogenic process and its component plant items as appropriate to their type and duty to maximise performance
3 Diagnose and take action on abnormal situations in accordance with procedures
  • 3.1 Monitor cryogenic process and its component plant items frequently and critically throughout shift using measured/indicated data and senses as appropriate
  • 3.2 Recognise conditions likely to give rise to brittle fracture and take action required by procedures
  • 3.3 Identify critical exposure temperature (CET) and take action to minimise its impact
  • 3.4 Describe impacts of any changes upstream and downstream
  • 3.5 Recognise actual and developing situations which may require action
  • 3.6 Apply operational knowledge to resolve problems
  • 3.7 Take other actions on abnormal situations which cannot be resolved during the shift to ensure safety and the resolution of the situation
  • 3.8 Follow through items initiated until final resolution has occurred
4 Isolate and de-isolate plant
  • 4.1 Complete any required pre-start checks, including safety systems
  • 4.2 Start up/shut down cryogenic process according to the cryogenic plant type and duty in liaison with other personnel
  • 4.3 Monitor the start-up process and take action to ensure operating parameters are achieved
  • 4.4 Start up/shut down/changeover component plant items within unit according to their type and duty in liaison with other personnel
  • 4.5 Isolate entire cryogenic process and/or any component plant item
  • 4.6 Make safe for required work
  • 4.7 Check cryogenic process plant/plant item is ready to be returned to service
  • 4.8 De-isolate and prepare cryogenic process plant unit/plant item for return to service
