Performance Criteria numbering amended.

Required frequency and volume of evidence amended in Performance evidence.

Substantial amendments made in Assessment Conditions field, including: references to Industry Sectors, assessor and subject matter expert experience requirements, how assessment should be conducted and what it should confirm.

Performance Evidence

Evidence is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:

  • locates and applies applicable legislation, documentation, policies and procedures
  • implements requirements, procedures and techniques for safe, effective compressor operations including:
  • identifying issues likely to impact on plant performance and take appropriate action
  • predicting impact of a change in one unit/area on other plant units/area and communicate this to relevant people
  • demonstrates completion of operating compressors that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:
  • performing correct sequencing for starting up equipment
  • correctly operating and monitoring equipment including:
  • starting up compressors,
  • monitoring and controlling compressors,
  • changing compressor output,
  • maintaining plant effectiveness
  • test trips and alarms
  • prepare plant for maintenance/vessel entry
  • complete minor maintenance according to standard procedures
  • prepare plant for the introduction of gas and operation
  • performing checks and shutdown in sequence

Knowledge Evidence

The candidate must demonstrate knowledge in compressor operations through:

  • apply legislative, organisation and site requirements and procedures for:
  • risk assessment and management
  • statutory compliance
  • work health and safety
  • distinguishing between:
  • process gas
  • instrument
  • equipment (electrical/mechanical)
  • maintaining compressors
  • identifying causes of problems and isolate problems to item of equipment
  • applying principles of compressor operation
  • identifying the effects of temperature and compression ratio/the need for multi staging
  • interpreting pressure/temperature relationships and effects on condensation (e.g. moisture and/or gas)
  • applying control of output
  • identifying and applying causes of and remedies for surging
  • applying methods of resolving problem

Assessment Conditions

  • An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,
  • this unit must be assessed in the context of this sector’s work environment; and,
  • this unit must be assessed in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,
  • assessment may be conducted in conjunction with the assessment of other Units of Competency; and,
  • assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,
  • assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,
  • where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,
  • assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:
  • Industry sector

    AQF** Level

    Required assessor or Industry subject matter expert experience

    Other sectors

    Where this Unit is being assessed outside of the Resources and Infrastructure Sectors assessor and/or Industry subject matter expert experience should be in-line with industry standards for the sector in which it is being assessed and where no Industry standard is specified should comply with any relevant regulation.

    *Assessors can demonstrate current work experience through employment within Industry in a role relevant to the outcomes of the Unit; or, for external assessors this can be demonstrated through exposure to Industry by conducting frequent site assessments across various locations.

    **Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level
