Elements and Performance Criteria

Gas Systems may include but not limited to:
Custody Transfer Stations, Tanker transfer, decantation, Tempered Liquid Petroleum systems, field or district regulators, LPG systems, meters and regulators, transmission and distribution systems

Data acquisition may include:
Temperature, pressure and flow rates from regulator or custody transfer stations, water bath heater operation (water temperature, pilot light and main burner operation), faulty equipment (over pressure and under pressure, slamshut operation and filter problems), pipeline ruptures, security system monitoring and pressure and volume data for "balancing the system"

Resources may include:
Relevant personnel, relevant authorities, company standard operating procedures, materials, equipment manuals/specifications, personal protective equipment, fire safety systems and training resources.

Legislative requirements may include:
Occupational Health & Safety legislation, government acts & regulations, Australian Standards & Codes of Practice, environmental legislative requirements.

Relevant authorities and other stakeholders may include:
Government authorities, landowners, stakeholders, local councils, fire authorities, other utilities

Relevant documentation may include:
Specifications, drawings/plans, manufacturers specifications, company standard operation and safety procedures, company management plans and policies, work permits, hot work permits, Company forms and files, acts and regulations, contracts, recording/reporting, maintenance activities, inspection/incident reports.

Critical aspects of evidence
These will include identification of gas characteristics and system performance specifications, data acquisition and management systems, selection of appropriate equipment, interpretation, application, and compliance of relevant legislation. Australian Standards Codes of work practice and company standard operating procedures to ensure safety of personnel and security of supply. Authorise and process relevant documentation to permit activities to be undertaken, cancelled or completed. Reviewing and reporting of completed work.

Context of assessment
Assessment of competency, including attainment of relevant knowledge and skills may be made through practical demonstration in an on-the-job or off-the-job work environment or simulation of such an environment. Assessment must adhere to defined safety and regulatory guidelines.

Pre-requisites
This unit requires, as an entry, attainment of either Certificate III in Gas Operations, Certificate IV in Gas Operations or Diploma of Gas Operations. Entry may also be accepted from those with relevant diplomas of engineering and/or science. As such they would be expected to have sufficient underpinning knowledge and skills in mathematics and science which should accelerate their progress through this unit which leads to the Advanced Diploma in Gas Systems. However, should this not be the case a suitable bridging program is to form part of the entry requirement.

Knowledge and Skills
A knowledge of:
The chemical and physical characteristics of natural and liquefied petroleum gas, mathematical computations associated with gas storage, movement and metering, engineering principles and operating principles of the pipeline systems, appropriate environmental requirements, company standard operating procedures, site specific safety legislation and safety requirements, commissioning and decommissioning procedures, cathodic protection systems, industry awards and employee entitlements.
The ability to:
Coordinate the work of others, provide technical leadership and accurate instruction, communicate effectively, adhere to Occupational Health and Safety regulations, observe environmental and legislative requirements, apply the permit to work system including types of permits limitations, correctly read and interpret drawings and plans, correctly read, analyse, interpret and record data. Develop standard operating procedures, review and report on completed work.
