MUNICH, Germany OneSubsea has contracted Siemens Energy to provide a turnkey package for the Bacalhau oil field development in the presalt Santos basin offshore Brazil.

The Equinor-operated Bacalhau field is about 115 mi (185 k) off Sao Paulo, Brazil, at a water depth of 6,726 ft (2,050 m).

Siemens Energy’s scope of supply for the project will include pressure and temperature sensors for the subsea production system, electrical distribution equipment including flying leads, umbilical terminations, and connectors for subsea modules, and multi-leg harness assemblies.

Manufacturing will jointly take place in the company’s factory in Bømlo, Norway, and the subsea connector factory in Ulverston, UK. It will also supply a variable frequency drive for the FPSO vessel.

Jennifer Hooper, senior vice president, Industrial Applications Solutions for Siemens Energy, said: “Providing electrical distribution equipment and instrumentation as part of the complete turnkey package will reduce the number of required suppliers for the subsea production system. This will significantly lower interface risks and overall project complexity for OneSubsea.”

The pressure and temperature sensors will provide monitoring data for the production system on the seabed. The subsea connectors form part of the distribution system and will provide low voltage power and communications to the subsea xmas tree production system.

Installation and commissioning of the equipment are slated for 2022 and 2024.
