MODEC selects SUZEZ for FPSO seawater process plant

SUEZ – Water Technologies & Solutions has been awarded a contract by MODEC Offshore Production Systems (MODEC) for the supply of a seawater injection system including sulfate removal technology (SRU). The equipment will be located on-board a converted floating production, storage, and offloading (FPSO) vessel that MODEC is constructing on behalf of Woodside Energy (as operator of the Rufisque Offshore, Sangomar Offshore and Sangomar Deep Offshore joint venture) for the Sangomar oilfield located approximately 100 km south of Dakar, Senegal, Africa.

“This award marks the third SRU contract awarded by MODEC to SUEZ and is a sign of our growing and important relationship with the company,” said Kevin Cassidy, Executive Vice President of Engineered systems for SUEZ – Water Technologies & Solutions. “SUEZ is unique in the offshore oil industry because of our ability to manufacture membranes while also designing and building the process plants that use them. This contract is further validation that our technology drives value and optimises performance for FPSO operators.”

The award is for the design and supply of the complete seawater treatment plant with a 23 000 m3/d capacity, including coarse filtration, ultrafiltration (UF), nanofiltration (NF) and vacuum deoxygenation equipment. Site requirements call for the plant to produce water with sulfate levels below 40 ppm.

SUEZ is a manufacturer and supplier of the UF and NF membranes that the offshore oil and gas industry uses 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 prevents well souring by controlling sulphate reducing bacteria.

The contract includes project management, procurement, construction supervision, and delivery to MODEC’s integration yard.
