Veolia subsidiary bags another SWTI contract in Latin America

With four contracts for sulfate removal systems under its belt since last year, VWS Westgarth has found Latin America’s offshore market to be lucrative.
Veolia Water Technologies announced in September that its subsidiary VWS Westgarth had been granted an EPC contract from Yinson for an FPSO seawater treatment and injection (SWTI) system for an enhanced oil recovery project in Brazil’s Marlim field. The nanofiltration-based system will be able to process 240,000 bbl/d of water, reducing sulfate levels to below 100 mg/l and protecting against reservoir souring as well as barium and strontium scaling.
The SWTI contract is the fourth VWS Westgarth has won since October 2019 (see table below) and the first announced since the industry slump that began in the first half of 2020.
“Like all markets, offshore works have been impacted by the COVID-19 pandemic. We have been fortunate in the timing of our awards, and thanks to the capability and adaptability of our staff, we have managed to continue to make progress on our projects,” Brian Baillie, head of sales for VWS Westgarth, told WiO.
He added that Veolia’s Aquavista digital service has allowed VWS Westgarth to continue supporting clients through real-time remote asset monitoring in a period when travel restrictions have prevented engineers from going offshore.
Veolia delivered the world’s first commercial sulfate removal plant in 1992 and now has some 38 such systems installed across the globe, representing a nearly 40% market share. All the company’s recent SWTI contracts have been for projects in the Latin American market, which has been buoyed by continued interest in Brazil’s pre-salt opportunities and successive discoveries offshore Guyana, despite the downturn.
