Elements and Performance Criteria

1. Monitor equipment operation
   • Monitor equipment operation according to instrument/electrical equipment operating principles and parameters
   • Access and interpret relevant technical drawings and schematics to determine system faults
   • Issue permit to work to allow work to be undertaken
   • Verify equipment operation/performance through test procedures to ensure correct operation and to confirm identified problems from other sources
   • Correct operational variations through calibration and adjustment
   • Document operational variations
2. Test/repair equipment
   • Verify equipment is operating correctly and document test results
   • Apply appropriate troubleshooting techniques to determine the cause of operational faults
   • Rectify operational faults through the application of relevant maintenance procedures
   • Isolate, remove and dispose of faulty equipment, and install new equipment
   • Verify the performance of newly installed equipment to ensure it meets required operational parameters and conditions
   • Record all repairs/installations to provide historical records of the condition of system equipment
3. Recommission systems and equipment
   • Recommission repaired/installed equipment to online operation in the correct sequence at the required operational parameters
   • Monitor or activate systems to ensure they are operating both safely and effectively
   • Close out permit to work and restore site/system to normal operation
4. Compile and analyse reports
   • Collect information concerning deviations/repaired equipment and put into accepted reporting format
   • Compile reports ensuring they provide an accurate and ongoing record of deviations in pipeline processes and a current record of pipeline and equipment trends
   • Utilise information or reports for short and long-term deviation control planning

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Regulatory framework	The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used, and include one or more of the following: legislative requirements, including work health and safety (WHS) industry codes of practice and guidelines environmental regulations and guidelines Australian and other standards licence and certification requirements All operations to which this unit applies are subject to stringent health, safety and environment (HSE) requirements, which may be imposed through state/territory 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.
