UEGNSG060 Maintain SCADA controlled flow and pressure equipment and electronic gas measurement equipment

Modification History

Release 1. This is the first release of this unit of competency in the UEG Gas Industry Training Package.

Application

This unit involves the skills and knowledge required to maintain supervisory control and data acquisition (SCADA) controlled gas distribution and transmission station facilities in accordance with relevant legislation, codes of practice, regulations and workplace procedures. It includes gas station maintenance of equipment, including remotely operated and controlled valves, air loaded, and SCADA controlled regulators, Coriolis, and ultrasonic and electronic meters. This unit applies to the following types of gas stations, subject to workplace safety and duty of care requirements being met for the workplace: compressor stations custody transfer stations inlets and city gates scraper stations gas storage facilities SCADA controlled main line valves The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 V a.c. or 120 V d.c. Competency development activities in this unit are subject to regulations directly related to licensing. Additional and/or other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to workplace safety regulations.
