MAN Energy Solutions will supply eleven RB-type compressor trains to Offshore Frontier Solutions Pte. Ltd., a MODEC Group company. The compressor trains will be installed on a floating production storage and offloading vessel (FPSO) for the Raia project, in the Campos Basin, approximately 125 miles (200 km) off the coast of Rio de Janeiro.
Equinor, in partnership with Repsol Sinopec Brazil and Petrobras, will operate the FPSO, which is expected to produce up to 126,000 barrels of crude oil per day, and produce and export up to 16 million cubic meters of gas per day. The reservoir, located at a depth of around 9515 ft. (2900 m), is estimated to contain more than one billion barrels of oil equivalent.
MAN Energy Solutions’ scope of supply for the FPSO’s gas lift, injection and export application, which marks the largest single order ever received at MAN Energy Solutions Switzerland, includes eleven electrically-driven centrifugal-compression trains, deployed as follows:
- 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
- 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, whereas the high- and low-pressure units will be equipped with variable frequency drives. Additionally, the two medium-pressure compressor units will feature a special switch control system, enabling operators to choose between fixed speed and VFD operation according to their requirements. The delivery of the compressor trains is scheduled for the fourth quarter of 2024 and the first quarter of 2025.
The MAN compression systems, once operational, will help maintain field pressure, thereby maximizing the quantity and efficiency of gas production. First production is expected in 2028.
“We are proud to support the further development of Brazil’s energy industry with this important, large-scale project. With MODEC, we share a solid history of successful FPSO projects around the globe, and we look forward to continuing this excellent collaboration,” stated Basil Zweifel, Head of Sales & Project Management, Up- & Midstream at MAN Energy Solutions. “Meeting the stringent CO2 reduction goals for this project in the challenging deep-water environmental conditions requires a high degree of flexibility and efficiency.”
The FPSO will apply MODEC’s new build, full double hull design, developed to accommodate larger topsides and larger storage capacity than conventional tankers. Taking advantage of this larger topside space, this FPSO will be the second fully electrified FPSO equipped with Combined Cycle System for Power Generation which significantly reduces carbon emission compared with conventional gas turbine driven systems.
