Why OneSubsea for subsea separation?
Our separation solutions, including NATCO separation technology and PETRECO heritage designs, provide you with the optimal approach to two- and three-phase separation and solids removal. Compact separation units and the all-electric control system enable a smaller footprint for deepwater developments, and compact electrostatic separators offer an efficient method to separate water from heavy oil.
Core benefits
