As part of the Wheatstone DOMGAS processing facility development, Chevron Australia required the detailed design, fabrication, assembly and testing of a facility that meters and monitors the quality of the natural gas feed from the 200 terajoule per day domestic gas plant via a pipeline into the DBNGP.


The project scope included the combined full turn-key delivery of civil, structural mechanical, piping electrical, controls & instrumentation works and offsite testing & commissioning of the complete facility assembled in Perth prior to shipping to site.


The facility was assembled completely at Primero Groups workshop in Bibra Lake,powered up and given a complete IFAT testing regime prior to dis-assembling and packaging ready for delivery to site. Using its multi-disciplined delivery model Primero Group completed the works in-house and utilised our proprietary commissioning software system, ‘Checkmate’ to complete the electronic upload of commissioning checksheets in accordance with Chevron standards and specifications.


Primero performed the in-house hazardous areas verification and dossiers and the complete testing under supervision of Chevron commissioning teams.
