Unit of competency
Modification History
Release 1. Supersedes and is equivalent to PMAOPS234A Monitor and operate low pressure compressors
Application
This unit of competency covers the skills and knowledge required to operate low pressure compressors.
The compressor may be technically sophisticated and/or have sophisticated controls built in, but its operation is relatively simple. It may have essential ancillary equipment but the operation of this ancillary equipment is largely integrated with the normal operation of the compressor unit itself.
The compressors will typically be used to provide suction or a moderately low pressure only. One example is the operation of a low pressure, low volume screw compressor in a coal seam gas (CSG) gathering system.
This unit of competency applies to operators who are required to start up and shut down the equipment, complete routine checks, monitor its performance and make adjustments, identify problems and take appropriate action, and maintain records.
This unit of competency applies to an individual who may work alone although under routine direction and supervision. They may work as part of a team or group and will work in liaison with other shift team members and the control room operator, as appropriate.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
