Siemens Energy Was Hired by OneSubsea to Provide Equipment for Project in the Pre-salt Layer, in the Santos Basin
OneSubsea closed a contract with Siemens Energy for the supply of a ready package of equipment for use in the Bacalhau field, located in the pre-salt layer of the Santos Basin. Under the contract, Siemens will provide pressure and temperature sensors for the subsea production system of the field operated by Equinor. The agreement is a turnkey package, a type of contract where only one supplier is hired to perform the work from start to finish.

Project Provided by Siemens Energy for the Pre-salt Layer, in the Santos Basin
Siemens Energy will supply pressure and temperature sensors for the subsea production system of the field in the pre-salt layer of the Santos Basin. By providing monitoring data for the production system in the pre-salt layer, the sensors help operators make informed decisions and ensure safe and efficient production.
The contract between Siemens Energy and OneSubsea also includes electrical distribution equipment comprising suspended cables, umbilical terminations, connectors for subsea modules, and multi-leg harness assemblies. In addition, Siemens Energy will provide variable frequency drive (VFD) for the Floating Production, Storage and Offloading (FPSO) vessel in the field located in the Santos Basin.

The Agreement with OneSubsea Regarding the Supply of Equipment
Jennifer Hooper, Senior Vice President of Solutions at Siemens Energy’s Industrial Applications, states that supplying electrical distribution and instrumentation equipment as part of the complete turnkey package will reduce the number of suppliers needed for the subsea production system. Hooper also mentioned that this will significantly reduce interface risks and the overall complexity of the project for OneSubsea.

Projects Operated in the Bacalhau Field, in the Pre-salt Layer, in the Santos Basin
Siemens Energy reported that the installation and commissioning of the equipment will take place in 2022 and 2024. OneSubsea is part of the Subsea Integration Alliance, which also includes Subsea7.
The alliance recently received a subsea contract for umbilicals, risers, and flowlines (SURF) from Equinor for the development project of the field. With a 40% stake, Equinor is the operator of the Bacalhau field in the Santos Basin. Other field partners include ExxonMobil, Petrogal Brasil, and Pré-sal Petróleo.
The development of the field, where Siemens Energy will provide the equipment, will include 19 subsea wells linked to an FPSO, which will have a production capacity of 220,000 barrels per day and two million barrels of storage.
