MWH has been appointed by Origin Energy to provide detailed design services for two proposed water treatment facilities as part of the Australia Pacific LNG project.

The Australia Pacific LNG project is a 50:50 joint venture between Origin and ConocoPhillips and incorporates the upstream gas and water gathering and treatment facilities, which are the first stage of the coal seam gas to the Liquefied Natural Gas (LNG) production process. MWH is contracted to Australia Pacific LNG to prepare the detailed design of two 40 megalitre per day (Ml/d) microfiltration / ion exchange / reverse osmosis water treatment plants.  In addition, approximately 110ha of earthen ponds for raw feed, brine reject and brine concentrate water ponds are included in the design scope.

    Location: Surat and Bowen Basins, Brisbane, Australia
    Region: Asia Pacific
    Service Offering: Engineering & Design
    Market Sector: Oil & Gas
    Client Type: Private Sector
    Status: Complete
    Process investigation into brine concentration, to increase water recovery and lessen waste volumes, is a parallel scope activity being progressed with MWH and Australia Pacific LNG team members.

    Both proposed facilities are for sites within the Surat and Bowen basins, approximately 400km west of Brisbane.

    MWH will perform the work using a multi-disciplinary, international team that includes world-class water treatment and storage expertise from the United States augmented by engineering resources from New Zealand, Middle East, United Kingdom and India. This enables virtually 24 hour working with associated benefits for the client.

    MWH’s appointment follows the successful completion of two smaller assignments for Origin: an alternative layout for the water treatment facility and a front-end engineering design (FEED) completion.

    • Detailed Engineering Design
    • Co-Located team environment
    • Certainty of delivery under tight timeframes
