McDermott International has completed the first phase of the deep-water Atlanta Early Production System (EPS) for Queiroz Galvão Exploração e Produção (QGEP), located approximately 185 kilometers offshore southeast of Rio de Janeiro, Brazil.
McDermott performed the project management, engineering and offshore installation of all subsea hardware, including flexible pipes, umbilicals, umbilical termination assemblies, and associated equipment for the subsea umbilicals, risers and flowlines (SURF) project.
The company also provided the flexible and umbilicals load out, logistics base and associated services, the scope that was added to McDermott’s initial award.
“Our outstanding performance on this project demonstrates a strong track record in the region and positions our company for future opportunities. We look forward to the opportunity to perform additional scope of work for the future phases of the Atlanta field for QGEP,” said Paulo Veronesi, McDermott Brazil country manager.
McDermott used two vessels to execute the offshore scope, the North Ocean 102 performed the umbilical installation scope while the Skandi Niteroi, a third party vessel, performed the flexible installation.
“The load out of the flexibles and umbilicals was completed successfully in accordance with the original plan based on the planned schedule,” said Francisco Quaresma, McDermott’s project manager for the Atlanta EPS project. “Although a challenging project, we overcame every obstacle to deliver the work successfully and safely.”
The production system of Atlanta field is located at the Santos Basin in Block BS-4 in a water depth of approximately 1,550 meters. The EPS consists of a dedicated floating production storage and offloading (FPSO) vessel with a single point mooring (SPM) turret that connects to three wells and is equipped with horizontal Wet Christmas Trees (WCT) with individual vertical flowline connections.
Production from the EPS is estimated to reach 20,000 barrels a day with the commissioning of the first two wells and is expected to increase to 30,000 barrels a day with the commissioning of the third well.
Scheduled to start in 2021, the definitive production phase will integrate a larger FPSO with a processing capacity of 80,000 barrels a day and development of up to nine additional horizontal wells. It will also increase the field’s production capacity to 75,000 barrels a day.
QGEP holds a 30 percent interest and is the operator of Block BS-4. Other Atlanta partners include Dommo Energia (40%) and Barra Energia (30%).
