AUGSBURG, Germany — MODEC subsidiary Offshore Frontier Solutions has contracted MAN Energy Solutions Switzerland to supply 11 RB-type compressor trains for the FPSO operating for Equinor’s Raia development offshore Brazil.
The vessel will be moored 200 km from the coast of Rio de Janeiro in a water depth of 2,900 m. It will be capable of producing and exporting up to 126,000 bbl/d of crude oil and up to 16 MMcm/d of gas.
MAN’s compression systems will help maintain field pressure, allowing Equinor to maximize gas production volumes. Raia is set to come onstream in 2028.
The 11 electrically driven centrifugal compression trains for the FPSO's gas-lift, injection and export facilities will comprise:
- two trains with type RB 28-6+3 compressors as overhead units;
- two trains with type RB 45-4+5 compressors as low-pressure units;
- five trains with type RB 28-5 compressors as medium- and high-pressure units; and
- two trains with type RB 28-8 compressors as gas-injection units.
The overhead and gas-injection compressor units will be driven by fixed-speed electrical motors, while the high- and low-pressure units will feature variable frequency drives (VFDs).
In addition, the two medium-pressure compressors will have a switch control system that allows the operator to choose between fixed speed and VFD operation, according to requirements.
Deliveries will take place later this year and into first-quarter 2025.
