Siemens Energy to deliver subsea equipment for Bacalhau field

OneSubsea has selected Siemens Energy to provide a turnkey subsea equipment package for the Bacalhau field development in the Pre-salt region of the Santos Basin in Brazil.

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

The company will also supply a variable frequency drive (VFD) for the floating, production, storage, and offloading (FPSO) vessel.

Manufacturing will jointly take place in the Siemens Energy Boemlo factory in Norway and the subsea connector factory in Ulverston, UK.

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

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,” said Jennifer Hooper, senior vice president, Industrial Applications Solutions for Siemens Energy. “This will significantly lower interface risks and overall project complexity for OneSubsea.”

At the beginning of June, OneSubsea’s joint venture with Subsea 7 secured an EPCI contract for the subsea pipelines (SURF) and production systems (SPS) for Bacalhau.

The oilfield, previously known as Carcara, is located approximately 185 kilometers off Sao Paulo, Brazil, at a water depth of 2,050 meters.

Chinese shipyard BOMESC yesterday, 9 June, cut the first steel for the topside modules for the FPSO that will operate on the Bacalhau field.
