Siemens will supply underwater electrical equipment for Bacalhau

Overseas staff

Munich, Germany – OneSubsea has engaged Siemens Energy to provide a turnkey package for the development of the Bacalhau oilfield in the pre-salt Santos Basin offshore Brazil.

The Bacalhau field operated by Equinor lies approximately 115 mi (185 k) offshore Sao Paulo, Brazil in a water depth of 6,726 feet (2,050 m).

Siemens Energy’s scope of supply for the project will include pressure and temperature sensors for the subsea generating system, electrical distribution equipment including jumper cables, umbilical terminations and connectors for the underwater modules, and multi-leg beam sets.

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

Jennifer Hooper, Senior Vice President, Industrial Application Solutions for Siemens Energy, said, “Providing power distribution equipment and instrumentation as part of a complete turnkey package will reduce the number of vendors required. for the subsea production system. This will significantly reduce 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 underwater connectors are part of the distribution system and will provide low voltage power and communications to the underwater Christmas tree production system.

The installation and commissioning of the equipment are scheduled for 2022 and 2024.
