PMAOPS221B Operate and monitor prime movers

Modification History

Not applicable.

Unit Descriptor

Unit descriptor	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.

Application of the Unit

Application of the unit	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.

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, 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.

Range Statement

RANGE STATEMENT
The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.

Context	This unit of competency includes all such items of equipment and unit operations which form part of the production/processing system. For your plant this may include (select relevant items): diesel, gas and petrol reciprocating engines turbine engines electric motors governing systems power supply safety and shutdown systems cooling systems.
Problems	Typical problems for your plant may include: variation in power/fuel supply vibration overheating fouling of turbine/engine/exchangers lubrication quality ancillary equipment failures. prime mover failure or malfunction electrical failure or malfunction mechanical failure/malfunction equipment design deficiencies quality measurement inaccuracy, eg analyzer, manual sampling deficiencies fuel quality.
Appropriate action	Appropriate action includes: determining problems needing action determining possible fault causes rectifying problem using appropriate solution within area of responsibility following through items initiated until final resolution has occurred reporting problems outside area of responsibility to designated person.
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 temporary instructions any similar instructions provided for the smooth running of the plant. For the purposes of this Training Package, 'procedures' also includes good operating practice as may be defined by industry codes of practice (eg Responsible Care) and government regulations.
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.
