Multiphase Compressor

OneSubsea’s multiphase compressor is a wet gas compressor with no requirements for an upstream separation facility or an antisurge system, which simplifies its subsea system requirements. The compressor is a contrarotating machine specifically designed for pressure boosting of unprocessed wellstream. Developed in collaboration with Statoil, this configuration allows for a compact design that is easy to install by use of light intervention vessels, and is based on the well-proven design developed for subsea booster pumps. The compressor is capable of handling high liquid contents without mechanical issues, with gas volume fractions typically ranging from 95% to 100%. The application of a wet gas compressor in the subsea environment eliminates the need for preprocessing in a subsea compression system, thus enabling the deployment of simplified subsea systems at lower capital expenditures and field development costs.
