Elements and Performance Criteria

Gas Systems
Gas systems could include transmission and distribution pipelines, storage facilities, underground storage, LPG installations, tankers and storage facilities.

Gas Characteristics
Gas characteristics could include temperature, chemical composition, pressures and pressure reduction, reserve quantities and LPG evaporation rates.

Relevant resources may include:
Relevant personnel, materials and equipment, personal protective equipment, company standard operating procedures, equipment manuals, training resources.

Legislative requirements may include:
Occupational Health & Safety, government acts and 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, statutory bodies

Relevant documentation may include:
Contracts, specifications, drawings/plans, manufacturers specifications, work permits, company standard operation and safety procedures, company management plans and policies, company forms and files, laws and codes of practice.

Critical aspects of evidence
These will include the identification of gas system characteristics and future demands, resources requirements within budgetary restraints including maintenance costs, performance standards and security of supply, pressure and temperature control equipment, as well as interpretation and application of relevant legislation, Australian Standards, codes of work practice and company standard operating procedures to ensure safety, commissioning procedures, review and reporting.

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.

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 operating principles of pressure and temperature control equipment and their performance characteristics, pipeline system, design requirements of a gas system, including the interdependence of associated systems, relevant mathematical calculations, relevant understanding of cathodic protection, project management and costing, appropriate environmental requirements, company standard operating procedures, site specific safety legislation.
The ability to:
Communicate effectively, calculate capacities, pressure and temperatures, interpret drawings, plans manufacturers specifications, analyse and interpret recorded data, review and report.
