Evidence Required
Assessment context and methods
Assessment for this unit of competency will be on an operating plant. 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 timely assessment of this unit of competency as modifications may not occur with sufficient frequency to allow 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
Competence must be demonstrated in the ability to specify the requirements and then select the best solution to meet the necessary and desirable requirements.
In particular look to see that:
safety, technical and economic aspects are all considered
the decision made can be justified on those criteria
all key stakeholders are kept well informed and agree with the decisions
the modification, and particularly its timelines, are a good fit for the overall plant requirements
obvious problems in related plant areas are recognised and an appropriate contribution made to their solution.
This will typically be assessed by a modification project on an operating plant. One complex project, or a number of simple projects, are required to demonstrate competence.
Resource implications
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.
Other assessment advice
In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.
It may be appropriate to assess this unit concurrently with:
PMACOM400A - Develop plant documentation
PMAOHS401B - Assess risk
Essential knowledge
Demonstration of competence in this unit must include knowledge of the following:
the operations of the plant and each major unit in it
the principles of operation of the equipment being investigated to the extent required to interpret technical specifications in a meaningful manner
the basics of plant economics and whole of life costing
hazard analysis principles (while it is beneficial, it is not expected that the candidate will be able to undertake HAZOP (or similar) analyses but will understand basic principles and be able to interpret and use the outcomes)
typical hazards with the type of equipment being investigated
OHS legislative requirements related to plant including registration and documentation requirements related to modification of registered plant.

Range Statement
Context
The need for the modification may arise from a continuous improvement project, as a result of an analysis of plant performance or from any other source. The modification may require the selection of any number of items of equipment such as:
pumps
heat exchangers
mixers
separators
columns
reaction kettles.
Classes of equipment (see element 2) means the selection between different members of an overall class such as:
heat exchangers - various types of shell and tube, plate, etc.
mixers - propellers, impellors, jet mixing, etc.
packed columns - rings, saddles, etc.
kettles - jacketed, coiled, etc.
Required minimum standards include:
OHS legislative requirements related to plant
industry and enterprise OHS standards
enterprise standards related to maintenance
output requirements
economic performance.
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.
