What an assessment for PMAOPS339 must cover

50 assessable components: 4 elements (27 performance criteria), 1 performance evidence and 17 knowledge evidence requirements, plus 5 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Operate well and gathering system according to procedures

1.1Receive and give shift handover
1.2Communicate with personnel to identify and coordinate work requirements
1.3Identify, control and report process system hazards
1.4Check for recent work undertaken on well and gathering system and address outstanding and incomplete work
1.5Check operational status of process system
1.6Perform routine site and equipment checks, and complete logs and paperwork, taking action on readings
1.7Adjust process system according to agreed operational parameters

2 Identify and respond to abnormal situations during operation

2.1Monitor well and gathering system frequently and critically throughout shift using own senses and measured and indicated data
2.2Monitor field data and instrumentation to ensure that product remains on specification
2.3Identify impacts of changes upstream and downstream
2.4Identify actual and developing situations that may require action
2.5Take action to remedy abnormal situations according to operating procedures
2.6Complete required documents outlining abnormal situation management and corrective action taken

3 Shut down and prepare well and gathering system for maintenance

3.1Prepare process system to be shut down according to operating procedures
3.2Complete pre-shutdown checks according to operating procedures
3.3Shut down process system according to operating procedures
3.4Identify, control and report shutdown hazards
3.5Monitor shutdown and identify abnormal situations which may require action
3.6Take action to remedy abnormal situations according to operating procedures
3.7Shut down and changeover duty and standby equipment according to operating procedures
3.8Isolate process system from energy sources

4 Prepare and start up well and gathering system

4.1De-isolate and prepare process system to be returned to standby or service
4.2Complete pre-start checks according to operating procedures
4.3Start up process system according to operating procedures
4.4Identify, control and report startup hazards
4.5Monitor startup and identify abnormal situations that may require action
4.6Take action to remedy abnormal situations according to operating procedures

Performance evidence

There must be evidence the candidate has completed the tasks outlined in the elements and performance criteria of this unit: - at least 2 times, each in a separate work context, including: - shutting down in an emergency.

Knowledge evidence

principles of: well design and construction, pumping, gas flow, gas and water separation, equalization
all items on a schematic of the production unit, including: operation of plant and equipment, downhole drawings (DHDs) and their application to plant and well operation
types of wells and gathering systems, including free-flow and pumped wells
draining and venting requirements
remote terminal unit functions, operation and abnormal situations
interactions between plant items and processes
operating parameters and integrity limits, and product specifications and tolerances including flange pressure and temperature ratings (basic), temperature, pressure and flow
impact of external factors (including variations in weather and feed)
procedures for starting, stopping, operating, controlling and isolating the system
functions of major components and troubleshooting techniques
local lease and well operations requirements, arrangements and constraints
well services handover and intervention procedures
reservoir management, hydraulics, hydrates, hydrate inhibition, subsea as appropriate
physics and geology to the level of being able to provide an overview of the science of the well and gathering system process, including coal seam gas (CSG) formation, structure and completions, coal type and structure, well design and construction, fluid dynamics and statics as relevant to the system, natural gas and oil characteristics, hydrate formation, cathodic protection (basic), static electricity and earthing, corrosion control and chemical handling, and safety data sheets (SDS)
well and gathering system abnormal situations and required action, including but not limited to: leakage, solids (formation fines), vibration, loss of control of pressure and/or flow, hydrate formation and blockages, liquid slugging, corrosion, erosion, sulphate-reducing bacteria, scale formation, equipment failure, change in product parameter (temperature, flow, pressure or level), fouling or contamination
hierarchy of control
wells and gathering systems hazards: possible causes, potential consequences, appropriate risk controls, escalation and reporting procedures.

Foundation skills

Learning skills: to follow instructions, monitor process and select appropriate procedure.
Reading skills: to follow written procedures and documentation.
Writing skills: to complete workplace documentation.
Oral communication skills: to liaise and coordinate with team members, the control-room operator and senior operators.
Numeracy skills: to monitor field data, instrumentation and process parameters, including calculating volumetric flow rate and equipment efficiencies.

Questions about assessing PMAOPS339

What does an assessment tool for PMAOPS339 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for PMAOPS339 needs to address all 50 unit components: 4 elements with 27 performance criteria, 1 performance evidence requirements, 17 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for PMAOPS339?

Auditori pulls the current release of PMAOPS339 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for PMAOPS339 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing PMAOPS339 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of PMAOPS339, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
