Unit of competency

Modification History

Release 1. Supersedes and is equivalent to PMAOPS223B Operate and monitor valve systems

Application

This unit of competency covers the skills and knowledge required to operate and monitor valves and ancillary equipment as part of controlling a process.

The valves covered by this unit of competency may be part of a hydrocarbons transport pipeline, gas distribution network or similar process.

This unit of competency applies to operators who are required to operate, monitor and maintain the equipment using relevant procedures and identify operational problems and take appropriate action.

This unit of competency applies to an individual who may work alone although under routine direction and supervision. They may work as part of a team or group and will work in liaison with other shift team members and the control room operator, as appropriate.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

  • flammability and explosivity
  • hazardous products and materials
  • unauthorised personnel
  • sharp edges, protrusions or obstructions
  • slippery surfaces, spills or leaks
  • extreme weather
  • other hazards that might arise

Routine problems 

Routine problems must be resolved by applying known solutions.

Routine problems are predictable and include one or more of the following:

  • vibration/resonance
  • blockages/hydrates

  • valve seal leakage
  • valve stem leakage
  • mechanical failure (e.g. plug/gate)
  • valve sticking

Known solutions are drawn from one or more of the following:

  • procedures
  • training
  • remembered experience

Non-routine problems must be reported according to according to relevant procedures.

Action 

Action in accordance with procedures includes the following:

  • determining problems needing action
  • determining possible fault causes
  • rectifying problem using appropriate solution within area of responsibility
  • following through items initiated until final resolution has occurred
  • reporting problems outside area of responsibility to designated person

Operate 

Operate is to monitor, adjust/change the plant item/unit/system to meet specifications, by one or more of the following:

  • manually in the plant
  • using local controller in the plant
  • using the process control system in the control room

Valves 

Valves include one or more of the following:

  • globe, butterfly, ball and gate valves
  • control valves
  • isolation valves
  • non-return or check valves
  • pressure relief valves

Assessment requirements

Modification History

Release 1. Supersedes and is equivalent to PMAOPS223B Operate and monitor valve systems

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria, and include the ability to:

  • operate and adjust valves to meet job specifications
  • undertake operational maintenance according to procedures
  • recognise early warning signs of equipment/processes needing attention or with potential problems
  • determine the most likely cause of routine problems
  • take appropriate action to ensure a timely return to full performance
  • isolate and de-isolate equipment
  • identify hazards and apply hazard control procedures.

Knowledge Evidence

Evidence must be provided that demonstrates knowledge of:

  • valve equipment operating parameters, such as pressures, temperatures and flows
  • flow volume calculations
  • flow velocity calculations
  • relevant process material properties such as fluid corrosive properties, fluid erosive properties
  • principles of operation of valves
  • physics and chemistry relevant to the valves and the materials processed
  • routine problems, faults and their resolution
  • relevant alarms and actions
  • correct methods of operating and controlling valves
  • types and causes of problems within operator's scope of skill level and responsibility
  • hierarchy of control
  • hazards that may arise in the job/work environment, and:
  • their possible causes
  • potential consequences
  • appropriate risk controls.

Assessment Conditions

  • The unit should be assessed holistically and the judgement of competence based on a holistic assessment of the evidence.
  • The collection of performance evidence:
  • should occur over a range of situations which include typical disruptions to normal, smooth operation of an operating plant
  • will typically include a supervisor/third-party report or other evidence, focusing on consistent performance and problem recognition and solving. A supervisor/third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency
  • must include the use of appropriate industrial valves applicable to this unit
  • may use industry-based simulation for part only of the unit where safety, lack of opportunity or significant cost is an issue.
  • Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
  • Assessment in a simulated environment should use evidence collected from one or more of:
  • walk-throughs
  • pilot plant operation
  • demonstration of skills
  • industry-based case studies/scenarios
  • ‘what ifs’.
  • Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept).
  • Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
  • Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
  • The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
  • Foundation skills are integral to competent performance of the unit and should not be assessed separately.
  • Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
  • In addition, the assessor or anyone acting in subject matter expert role in assessment must demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they must assess with a subject matter expert who does meet these requirements.
  • Technical competence can be demonstrated through one or more of:
  • relevant VET or other qualification/Statement of Attainment
  • appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions
  • appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions
  • Currency can be demonstrated through one or more of:
  • being currently employed undertaking the type of work being assessed
  • being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures
  • having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment
  • conducting on-the-job training/assessments of the type of work being assessed
  • being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work
