Unit Descriptor

Unit descriptor 

This unit covers the generation, provision or 'making' of services for use by a plant. While this generally would apply to a remote or off shore plant, it may also be appropriate for other plants.

Application of the Unit

Application of the unit 

In a typical scenario an operator uses and monitors a range of equipment which provides essential fluids for process support. These fluids may be used for instrumentation, cooling, stabilising, scrubbing and hazard reduction, fire suppression and other uses.

The operator would:

  • identify and report operational problems
  • be aware of and contribute to a safe working environment
  • contribute to the safe production of utility and support fluids
  • operate, monitor and maintain equipment following relevant procedures.

Generally the operator would be part of a team during start up and shut down procedures and would be expected to be capable of demonstrating competence in all parts of this unit for the services relevant to their plant. At all times they would be liaising and cooperating with other members of the team.

This unit does not require the operation of a central control panel.

This unit does not cover the generation of steam using a fired boiler - see

UTPNEG162A Operate and monitor boiler steam /water cycle 

nor the use of these services as part of operating a process plant - see

PMAOPS204B Use utilities and services

Required Skills and Knowledge


This describes the essential skills and knowledge and their level, required for this unit.

Required skills 

Competence includes the ability to isolate the causes of problems to an item of equipment within the production system and to be able to distinguish between causes of problems/alarm/fault indications such as:

  • instrument failure/malfunction
  • electrical failure/malfunction
  • mechanical failure/malfunction
  • product parameters (temperature, flows, pressure and levels).

Required knowledge 

The knowledge referred to in the Evidence Guide for this unit includes:

  • identify all items on a schematic of the system and describe the function of each
  • principles of equipment operation
  • physics relating to the particular process
  • chemistry relating to the process
  • process equipment operating parameters
  • emergency back up systems
  • process control systems and instrumentation
  • the differences between high pressure and low pressure systems.
  • process parameters and limits, eg temperature, pressure, flow, pH
  • duty of care obligations
  • hierarchy of control
  • communication protocols, eg radio, phone, computer, paper, permissions/authorities
  • routine problems, faults and their resolution
  • relevant alarms and actions
  • plant process idiosyncrasies
  • correct methods of starting, stopping, operating and controlling process
  • corrective action appropriate to the problem cause
  • function and troubleshooting of major components and their problems
  • types and causes of problems within operator's scope of skill level and responsibility.

Evidence Guide


The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Assessment of this unit should include demonstrated competence on actual plant and equipment in a work environment. The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. Assessment will occur over a range of situations, which will include disruptions to normal, smooth operation.

Simulation may be required to allow for assessment of parts of this unit. Simulation should be based on the actual plant and will include walk-throughs of the relevant competency components. Simulations may also include the use of case studies/scenarios, role plays and 3D virtual reality interactive systems. In the case of evacuation training or training for competencies practised in life threatening situations, simulation may be used for the bulk of the training.

This unit of competency requires an application of the knowledge contained in the use of the equipment, to the level needed to maintain control and recognise and resolve problems. This can be assessed through questioning and the use of what-if scenarios both on the plant (during demonstration of normal operations and walk throughs of abnormal operations) and off the plant.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action. The emphasis should be on the ability to stay out of trouble rather than on recovery from a disaster.

Consistent performance should be demonstrated. In particular look to see that:

  • early warning signs of equipment/processes needing attention or with potential problems are recognised
  • the range of possible causes can be identified and analysed and the most likely cause determined
  • appropriate action is taken to ensure a timely return to full performance
  • obvious problems in related plant areas are recognised and an appropriate contribution made to their solution.

These aspects may be best assessed using a range of scenarios/case studies/what-ifs as the stimulus with a walk-through forming part of the response. These assessment activities should include a range of problems, including new, unusual and improbable situations, which may have been generated from the past incident history of the plant, incidents on similar plants around the world, hazard analysis activities and similar sources.

Context of and specific resources for assessment 

Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations. A bank of scenarios/case studies/what-ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Method of assessment 

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

In a major hazard facility, it may be appropriate to assess this unit concurrently with:

  • MSAPMOHS200A Work safely .

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

Range Statement


The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.
