RIO DE JANEIRO – McDermott International Inc. has completed the first phase of the deepwater Atlanta early production system (EPS), 115 mi (185 km) offshore Brazil for Queiroz Galvão Exploração e Produção S.A. (QGEP).
McDermott performed the project management, engineering, and installation of all subsea hardware, including flexible pipes, umbilicals, umbilical termination assemblies, and associated equipment for the subsea umbilicals, risers and flowlines project. It also provided the flexible and umbilicals load out, logistics base, and associated services.
The company’sNorth Ocean 102 performed the umbilical installation scope while the Skandi Niteroi, a third-party vessel, performed the flexible installation.
The Atlanta EPS project is the first engineering, procurement, construction, and installation (EPCI) lump-sum project by the McDermott team in Brazil.
The production system of the Atlanta field is in the Santos basin in block BS-4 in a water depth of about 5,085 ft (1,550 m). The EPS consists of an FPSO vessel with a single point mooring turret, which connects to three wells (2HP and 3H already drilled and 4HA to be drilled in late 2018 or early 2019), and is equipped with horizontal wet christmas trees with individual vertical flowline connections.
Production from the EPS is estimated to reach 20,000 b/d with the commissioning of the first two wells and is expected to increase to 30,000 b/d 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 b/d and development of up to nine additional horizontal wells. It will also increase the field’s production capacity to 75,000 b/d.
QGEP holds a 30% interest and is the operator of block BS-4, with partners Dommo Energia (40%) and Barra Energia (30%).
