WESTSIDE PROLEUM, a subsidiary of MINPROVISE, provides multidiscipline engineering fabrication, construction services, along with labour solutions and products supply.

WESTSIDE PROLEUM works within the accreditations ISO 9001, ISO 14001, OHSAS18001 and AS/NZS4801 maintained and held by MINPROVISE.

WESTSIDE PROLEUM offers the benefits of an integrated service in which all stages of manufacture are carried out at our purpose-built facility.
