McDermott Completes Phase 1 of QGEP Atlanta Early Production System
Wednesday 11 April 2018
McDermott International, Inc. announced it completed the first phase of the deep-water Atlanta Early Production System (EPS), located approximately 115 miles (185 kilometers) offshore southeast of Rio de Janeiro, for independent Brazilian Exploration and Production company Queiroz Galvão Exploração e Produção S.A. (QGEP).
McDermott successfully 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. McDermott also provided the flexible and umbilicals load out, logistics base and associated services. This additional scope was added to McDermott’s initial award.
The Atlanta EPS project is the first engineering, procurement, construction and installation (EPCI) lump sum project by the McDermott team in Brazil.
McDermott’s load out base was located at Porto do Açu, approximately 155 miles (250 kilometers) north of Rio de Janeiro. The McDermott Atlanta project team developed the appropriate base lay-out and facilities, which was fully equipped with the required loading equipment and offices.
McDermott used two vessels to execute the offshore scope. McDermott’s North Ocean 102 performed the umbilical installation scope while the Skandi Niteroi, a third party vessel, performed the flexible installation.
Project Details
The production system of Atlanta field is located at the Santos Basin in Block BS-4 in a water depth of approximately 5,085 feet (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 (2HP and 3H already drilled and 4HA to be drilled late 2018 or early 2019) 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 and is the only Brazilian operator in the Santos basin pre-salt exclusion zone. Other Atlanta partners include Dommo Energia (40%) and Barra Energia (30%).
