Operate and monitor prime movers

Assessment tool

Version 1.0
Issue Date: April 2024


Often the operation of a prime mover will require a 'ticket' (special licence) to operate and local requirements need to be checked. This unit includes starting up/shutting down and monitoring the performance of the equipment and a full understanding of HSE requirements including emergency situations.

The operations technician would:

identify and report operational problems

be aware of and contribute to a safe working environment

contribute to the safe and productive operation of the prime mover

monitor, shut down and start up prime mover and ancillary equipment using relevant procedures.

This unit does not apply to close coupled motors which are operated as part of the equipment, eg for pump motors see PMAOPS201B Operate fluid flow equipment.

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. At all times they would be liaising and cooperating with other members of the team.

This unit covers the operation of a prime mover and its ancillary equipment is used to drive a high pressure pump or compressor. The prime mover may be a large high voltage/current electrical motor, a turbine or a diesel engine. It is a complex, independent item of equipment with a specialised start up and shut down procedure. It may have its own control panel and inbuilt vibration monitoring equipment.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 of training for competencies practised in life threatening situations, simulation may be used for the bulk of the training.

This unit requires an application of the knowledge contained in the use of the prime movers and its integral 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 prime mover, incidents on similar prime movers around the world, hazard analysis activities and similar sources.

Context of and specific resources for assessment

As a general rule assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating competence 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.

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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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

Required skills

efficient and effective operation of plant/equipment

hazard analysis

completing plant records

communication

problem solving.

Required knowledge

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

all items on a schematic of the prime mover and the function of each

prime mover operating parameters and capacities

prime mover operating principles, including fuel injection, lubrication, cooling, ignition, induction and exhaust power supply

equipment operation, including flows, pressures temperatures and speeds

equipment terminology

sampling and testing techniques

process drawings, eg PID, PFS

cause and effect

safety systems and procedures

job hazard analysis.

physics and chemistry relevant to the prime mover

process parameters and limits, eg temperature, pressure, flow

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 flow

corrective action appropriate to the problem cause

function and troubleshooting of major internal components and their problems.

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.

Codes of practice/ standards

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent health, safety and environment requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
