MAN Sending Seven Compressors For FPSO

By DJ Slater28 October 2020

MAN Energy Solutions will supply five radial compressor and two screw compressor trains for Equinor’s first Brazilian offshore gas extraction project.

MODEC, a supplier and operator of offshore systems for the global oil and gas industry, ordered the compressor trains, which will be installed aboard the largest floating production storage and offloading (FPSO) vessel to ever be delivered to Brazil, MAN said. The vessel will be deployed in the Bacalhau field, about 115 miles (185 km) off the Brazilian coast – south of São Paulo – at a water depth around 6726 ft. (2050 m).

The FPSO plant will be designed to produce and process up to 220,000 barrels of crude oil and up to 530 Mcfd (15 X 106 m3/d) of gas. 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 flow-rate and efficiency. The type RB compressors (two RB 45-4+5 and three RB 28-6) – which are driven by an electric, fixed-speed motor – will be used 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 compressors pressurize any flash gas created and return it to the process instead of burning it off into the atmosphere.

While 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.
