Auxiliary applicationsThe complex processes performed on a typical FPSO rely on the performance of dozens of pumps handling a variety of liquids under widely varying process conditions.
Crude oil offloadingDepending on the FPSO design, a booster pump is often required to export crude oil delivered to deck level by the FPSO cargo system.
Firewater systems (fire fighting)Firewater pumps are the heart of an FPSO’s firefighting system. It is vital that the pumps be reliable in extreme conditions and run for extended periods of time.
Flow assurance (dead oil / hot oil)Pumps for flow assurance service, also known as dead oil and hot oil circulation, are critical to maintain oil production in deep cold water. Though usually driven by an electric motor, the Sulzer BB3 and BB5 pumps can be engineered with diesel engine drivers. Along with our reputation for quality and efficiency, our pumps are right for this service.
Multiphase pumpingHelico-axial multiphase pumps (MPP) are used to boost unprocessed well streams, enabling liquid / gas mixtures to be transported over long distances without the need for prior phase separation.
Seawater liftSulzer builds both lineshaft and submersible motor vertical seawater lift pumps. Sulzer SMHv and SMDv pumps are vertical shaft in BB1 casing.
Seawater treatmentWith enhanced oil recovery methods, often prior to injection sea water needs to be treated to remove or reduce salt content. Sulzer’s pumps achieve this by delivering sea water to the SRU / SWRO membrane racks.
