This competency assumes that the technician responsible for the debottlenecking takes the overall responsibility for the project, but would work with the support of other company and external experts. This extends to the coordination of the required modifications/changes. This unit does not cover the optimisation of plant by modification of process, procedures or practice (see MSAPMOPS400A Optimise process/plant area).
This unit does not cover work requiring special certification (eg, registered structural engineer) but may include working with such people and providing process and product expertise.
In a typical scenario, it is desired to increase the throughput of a plant. A study is undertaken to identify the rate limiting step/process/plant unit (bottleneck) and then changes are made to plant or process conditions to increase the throughput of this unit. The making of plant modifications is not part of this unit (see PMAOPS600C Modify plant).
This competency may require the technician to work with technical experts to complete the debottlenecking project. Typically this unit would be applied to either a small plant or a section/area of a larger plant.
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 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 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. | |
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. It may be appropriate to assess this unit concurrently with units which deal with: plant documentation assessing risk. energy and mass balances plant modifications | |
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 |
This competency includes the following skills: analysis mathematics communication priortisation leadership |
Required knowledge |
Competence in this unit includes the following knowledge: 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 material and/or energy balances 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 processes being investigated OHS legislative requirements related to plant, including registration and documentation requirements related to modification of registered plant |
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. |
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. Required minimum standards include: OHS legislative requirements related to plant industry and enterprise OHS standards enterprise standards related to maintenance output requirements economic performance |
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.
