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.

Simulation may be required to allow for assessment of parts of this unit. It is possible that a simulation will be required to ensure that the technician is competent before taking a significant role in a commissioning activity. Commissioning is an infrequent and often frenetic activity and so it may not be practical or equitable to wait for an actual commissioning to occur to use this as the basis for assessment. 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 and role plays.

This unit of competency requires a significant body of knowledge which will 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:

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 commissioning stays on schedule

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 relevant OHS 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.

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

Required skills

hazard analysis

completing plant records

communication

problem solving.

Required knowledge

Competence to include the ability to apply and explain:

HAZOP (or similar) study process and the interpretation of findings

results and impact of a HAZAN (or similar) study

the process of hazard identification, risk assessment and control

hierarchy of control

sources of hazard information (such as Material Safety Data Sheets)

principles of operation of equipment

interpretation of design drawings, schematics and manuals

physics and chemistry relevant to the plant and the materials processed or produced

process parameters and limits, eg temperature, pressure, flow, pH

duty of care obligations

expected problems, faults and their resolution

possible alarms and actions

any known or expected plant process idiosyncrasies

all items on a schematic of the plant and the function of each

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 to be expected

principles of operation of instrumentation

principles of basic control systems

distinguish between the following problem sources, and their avoidance:

chemical

instrument

equipment (electrical/mechanical)

maintenance.

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.

Appropriate authorities

Appropriate authorities may include:

local councils

road authority

sewerage and stormwater authorities

providers of services such as electricity, water and telephones.

Codes of practice/ standards

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

Plant

Plant covers on or off shore plant, well heads and also transmission pipelines or similar.

Commissioning

Commissioning refers to the start-up of a new plant or plant unit and the associated equipment for the first time.

Commissioning/re-commissioning activities

Commissioning/recommissioning activities may include:

trial running of equipment

use of trial materials in plant

safe introduction of process materials to plant

producing product within specification

bringing plant to design rates

solving operational problems

disposal of waste generated in the start-up.

Documentation

Documentation may include:

operating procedures

OHS and environmental legislative requirements

manufacturer specifications

appropriate authority approvals

quality assurance inspection and test reports.

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.

Plant/pipeline systems

Plant/pipeline systems may include:

pipes

valves

operating units

electrical and electronic components

PLCs/DCS control (programmable logic controllers, distributed control systems) or other plant controls

cathodic protection

pressure/flow/temperature etc regulation and meters.

Pre-commissioning

Pre-commissioning activities may include:

checking plant is built to design

ensuring plant is safe to operate

ensuring plant area is clean and clear of debris

ensuring the plant internals are clean and clear of debris

functional checking of equipment and ancillaries.

Procedures

All operations are performed in accordance with standard operating procedures.

Procedures may be written, verbal, computer-based or in some other form. They include:

all work instructions

standard operating procedures

formulas/recipes

batch sheets
