MAN Energy Solutions (MAN) will supply six compressors for the floating production storage and offloading (FPSO) vessel, Anna Nery, to be built and operated by Yinson. The vessel will be located in the Petrobras owned Marlim and Voador fields of the Campos Basin, about 93 miles (150 km) off the coast of Rio de Janeiro, Brazil.
MAN will provide four RB-type centrifugal-compressor trains for gas production and export, and two screw-compressor trains, which will be put into operation as vapor-recovery units.
MAN’s scope of supply includes four RB-type compressor trains (2 × RB 56-4+4 and 2 × RB 28-7) with hydraulic, variable-speed gearboxes driven by an electric motor, which will be designed, manufactured, and tested at MAN’s facility in Zurich, Switzerland. The machines will be used for gas export as well as gas lift to maximize the quantity and efficiency of gas production, the company said.
The double-screw compressor trains – type CP200/CP128/B85 – driven by fixed-speed electric motors, will be used as vapor-recovery units. Instead of flaring any flash gas into the atmosphere, the screw compressors will instead pressurize it and feed it back into the process leading to increased gas-production efficiency as well as reduced CO2-emissions. Design, manufacturing, and testing of the screw compressors will take place in Oberhausen, Germany.
Compressor installation and commissioning is scheduled for second-quarter 2021.
Scheduled for deployment in second-quarter 2023, Anna Nery will have a production capacity of up to 70,000 barrels of oil per day, 250,000 barrels of liquid per day, and 142 MMscfd (4.02 x 106 m3/d) of gas.
