This unit involves the skills and knowledge required to select and commission equipment for pressure and temperature control in a natural gas or liquefied petroleum gas (LPG) system.

It includes determining equipment pressure and temperature control specifications and performance parameters for natural gas or LPG system. It also includes selecting, planning and overseeing commissioning of equipment and validating natural gas or LPG control system performance.

No licensing, legislative or certification requirements apply to this unit at the time of publication.
