Floating turbomachinery order

Published on: April 12, 2022

Siemens Energy was awarded a contract from Keppel Offshore & Marine to supply the topsides turbomachinery package for the P-78 floating, production, storage, and offloading (FPSO) vessel. The FPSO is owned and operated by Brazil-based Petrobras in partnership with Chinese CNOOC and CNODC and will operate in the Búzios Field of the Santos Basin, located approximately 200 kilometers (124 miles) off the coast of Rio de Janeiro in water depths ranging from 1,600 – 2,100 meters (5,249 – 6,890 feet).

Siemens Energy’s scope of supply includes the power generation and compression packages for the facility, as such as main gas, export gas, injection gas, and CO2 injection compressors. The power supply will be met with four gas turbine packages.

Main gas, export gas, and injection gas compression duties will be met with eight electric motor-driven compressor trains. Two additional trains featuring aeroderivative gas turbines driving centrifugal compressors will be used for reinjection of CO2 back into the reservoir. When complete, P-78 will have a processing capacity of 180,000 barrels of oil per day (bopd) and 7.2 million cubic meters of gas per day (mmscfd). Delivery of the equipment is slated for 2023. The P-78 FPSO is expected to enter operation in 2025.
