Unit Descriptor

Unit descriptor 

This unit of competency is an entry level competency for a field operator. It covers the basic skills required to monitor wells and associated equipment in the field and to recognise and report problems, but not necessarily to rectify problems or make adjustments.

Application of the Unit

Application of the unit 

This unit of competency applies to field operators who are responsible for a number of wells and their associated systems. In a typical scenario, the operator will be driving alone, on and off roads between wells and also to and from the base site or plant. While at a site, they will be monitoring well and equipment performance by taking readings, making checks, recording and reporting their findings in accordance with procedures. They will also be expected to identify hazards and take appropriate action.

This competency is typically performed by operators working independently while in communication with a field or plant operator with whom they would work as part of a team. At all times they would be liaising and cooperating with other members of the team.

Evidence Guide

EVIDENCE GUIDE 

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

This unit of competency requires an application of the knowledge contained in the use of the equipment, to the level needed to maintain control and recognise and resolve problems.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessment for this unit of competency will be on a plant.

It is essential that the equipment be understood and that the importance of critical material properties, settings and readings is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.

Consistent performance should be demonstrated. In particular look to see that:

  • appropriate inspections are made
  • required readings are taken
  • early warning signs of equipment processes needing attention or with potential problems are recognised
  • necessary actions are completed.

Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.

Context of and specific resources for 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 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 training for competencies practised in life-threatening situations, simulation may be used for the bulk of the training.

A bank of scenarios/case studies/what-ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment 

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
