Seabox™

The Seabox™ subsea water treatment module is installed on the seafloor, designed to treat 40 000 bpd of sea water for injection, directly into subsea wells or via topside. The Seabox™ module disinfects water and removes all solids down to 10 μm using electrolysis and long residence time. Subsea water treatment ensures operators’ flexibility to adjust capacity needs as well as implement water injection on fields otherwise found too expensive.

For arctic conditions, the Seabox™ module will mean a reduction in chemicals used, lower energy demand and reduced need for offshore manning. It is not obstructed by topside weight and space or distance to injection wells. The Seabox™ will accelerate production and increase recovery through flexibility and a more active reservoir management.

SWIT™

The SWIT™ subsea water treatment and intake technology, with the Seabox™ module as its cornerstone, utilizes filtration and membrane technology to tailor raw seawater to reservoir requirements – particle-free, low salinity or low sulfate water. The SWIT™ technology reduces the need for maintenance without compromising performance, all done subsea. Removing filtration and membrane equipment from topside facility reduces topside infrastructure and offshore manning. There is a significant reduction in CAPEX and OPEX, but still greater availability is achieved through the SWIT™ water treatment technology.

For arctic climate this solution provides a more environmental friendly approach to water treatment, due to decreased use of chemicals, power consumption and need for topside infrastructure.
