MODEC selects SUEZ technology for FPSO project in Brazil

MODEC Offshore Production Systems has awarded a multi-million dollar contract to SUEZ’s Water Technologies & Solutions for the supply of seawater sulfate removal technology.

MODEC is constructing a new FPSO vessel on behalf of Equinor Norway, the operator of the Bacalhau oilfield, and will use SUEZ ultrafiltration and nanofiltration membranes to reduce seawater sulfate levels to required levels.

The contract includes equipment supply, engineering, project management, procurement and construction supervision. Production capacity of the FPSO is 220 000 bpd and 15 million m3/d of gas.

“It is a great vote of confidence to have MODEC select SUEZ technology for this project and we look forward to continuing to be a strong partner,” said Kevin Cassidy, executive vice president, engineered systems for SUEZ – Water Technologies & Solutions. “With our expertise and capability, we have the global reach that MODEC has come to rely on and we are proud to be considered a preferred supplier on these essential projects.”

To produce oil, treated seawater must be injected into the reservoir. Commonly referred to in the industry as an SRU, seawater sulfate removal units using ultrafiltration (UF) and nanofiltration (NF) membranes are an essential part of this process and critical to the protection and operation of the assets onboard the FPSO.

SUEZ manufactures and supplies the UF and NF membranes that the offshore oil and gas industry relies on to remove sulfates and other divalent hardness ions from injection water, to enhance oil recovery. The removal of these ions reduces the tendency of barium sulfate and strontium sulfate scale to form in the reservoir and flowlines, and will also prevent well souring by controlling sulfate-reducing bacteria.

This latest award from MODEC marks the second contract with MODEC in a span of 6 months and is the fifth contract between SUEZ and MODEC in this space.
