MAN Energy Solutions (MAN) will supply seven compressor trains for an Equinor gas extraction project off the coast of Brazil. MAN will provide five radial compressor and two screw compressor trains for a floating production storage and offloading (FPSO) vessel to be deployed in the Bacalhau field, about 115 miles (185 kM) off the Brazilian coast, at a water depth of around 6725 ft. (2050 m).
The FPSO vessel, being built by MODEC, will produce and process up to 220,000 barrels of crude oil, up to 529 MMscf/d (15 x 106 m3/d), and inject up to 200,000 barrels of seawater per day. The minimum storage capacity will be two million barrels of crude oil.
The compressor systems will help maintain the pressure in the Bacalhau field, thereby maximizing the production flowrate and efficiency. The type RB compressors (2 × RB 45-4+5 and 3 × RB 28-6), which are driven by an electric, fixed-speed motor, will be utilized for gas-processing, full gas re-injection, and gas-lifting applications.
The two SKUEL 510 screw compressors will be used as vapor-recovery units. These pressurize any flash-gas created and return it to the process instead of burning it off into the atmosphere, increasing the efficiency of gas processing and reducing CO2 emissions.
The radial compressors will be designed, manufactured, and tested in Zurich, Switzerland. The screw compressors will be produced at the MAN site in Oberhausen, Germany. Delivery of all compressor trains is scheduled for the fourth quarter of 2021.
