Monitor and operate low pressure compressors
Assessment tool
Version 1.0
Issue Date: May 2024
This unit of competency applies to operators who are responsible for the operation of compressors which are relatively simple to operate. Typically the compressor may be used to provide suction or a moderately low pressure only. The compressor may be technically sophisticated and/or have sophisticated controls built in, but its operation is relatively simple. A typical example might be the operation of a low pressure, low volume screw compressor in a coal seam gas (CSG) gathering system.
This Training Package has three possible units of competency applicable to the operation of compressors:
MSAPMOPS100A Use equipment which is applicable to the typical, small, hired, skid or trailer mounted compressor where the major operation is to turn on and turn off and maybe monitor pressure and perhaps another variable or two (e.g. water removal)
PMAOPS234A Monitor and operate low pressure compressors (this unit) applies to low pressure, usually simple to operate compressors, but still ones requiring start-up/shutdown and some monitoring and adjustment
PMAOPS304B Operate and monitor compressor systems and equipment which is applicable to complex compressors, typically delivering high pressure and also requiring the operation of prime movers, intercoolers and forced lubrication systems. These compressors are usually high pressure, high volume compressors.
The operator will also be expected to:
identify hazards and take appropriate action
recognise problems
resolve routine problems
report other problems.
This competency is typically performed by operators working independently while in communication with a field or plant operator with whom they would work as part of a team. At all times they would be liaising and cooperating with other members of the team.
This unit of competency covers the operation of low pressure compressors which are typically relatively simple to operate. The compressor may, or may not, have a high level of technical complexity. The compressor may have essential ancillary equipment but the operation of this ancillary equipment is largely integrated with the normal operation of the compressor unit itself. It includes the recognition and resolution of routine only problems.
