OneSubsea Taps Siemens Energy for Bacalhau Subsea Sensors, Connectors
Schlumberger's OneSubsea has ordered a turnkey package from Siemens Energy for the Bacalhau field development project in the Pre-salt region of the Santos Basin. The Bacalhau oilfield, operated by Equinor, is located approximately 115 miles (185 kilometers) off Sao Paulo, Brazil, at a water depth of 6,726 feet (2,050 meters). Equinor sanctioned the field development, which will cost $8 billion, last week.OneSubsea, as part of Subsea Integration Alliance with Subsea 7, last week after the FID won the contract award for the delivery and installation of the subsea pipelines (SURF) and production

(formerly Carcará) project, offshore Brazil.The awarded work is required to finalize the technical definition of the proposed field development prior to Equinor making final investment decisions (FID) late 2020. The Bacalhau field is located 185 km from the coast of the State of São Paulo, in water depths of 2050 meters. It will Bacalhau (Carcará) will be the first greenfield development in the pre-salt by an international operator.Subsea 7 said Thursday that the contract was based on a two-step award. The FEED and pre-investment are starting now, with an option for the execution

equipment and underwater vehicles deployed from Brazil’s flagship oceanographic research vessel, Alpha Crucis, are to be tracked using Ultra-Short BaseLine (USBL) positioning technology supplied by Sonardyne Brasil Ltda.The 64-meter-long vessel, which is operated by the University of São Paulo, undertakes research projects spanning global climate change to biodiversity in Brazilian waters. It will be equipped with a Sonardyne Ranger 2 USBL high precision acoustic positioning system to enable the Alpha Crucis’ 21-strong science team to precisely track their instruments and sensors
Subsea 7 Wins Contract from Total in Brazil
Subsea 7 announced it has secured a contract from Total E&P do Brasil for the development of the Lapa North East field located approximately 300 kilometers off the coast of the State of São Paulo, at 2,150 meters water depth in the pre-salt Santos Basin.The contract is worth between $50 million and $150 million, Subsea 7 said.The work scope includes the transport, installation and pre-commissioning of 35 kilometers of flexible pipelines and 20 kilometers of umbilical, connecting five wells to the floating production, storage and offloading unit (FPSO) Cidade de Caraguatatuba.

SURF contract awarded to date in Brazil. The pioneering technology for connecting a large number of wells to a single FPSO was developed by the Petrobras’ research center (Cenpes) and Subsea 7, with the support of UFRJ (Federal University of Rio de Janeiro) and USP (University of São Paulo). The project required the installation of four huge 2,800ton submerged buoys approximately 250 meters below the surface. The system was designed to accommodate a combination of 45 risers/umbilicals for each field in a small area in a decoupled arrangement. Subsea 7’s scope was specifically
