  • Auxiliary applications
    The 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 offloading
    Depending 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.

  • Multiphase pumping
    Helico-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 lift
    Sea chest, lineshaft or electric submersible pumps. Whatever your seawater lift needs, Sulzer has a solution.
