Subsea Boosting Systems
For water, oil, and gas mixtures with high gas volume fractions
OneSubsea boosting pumps, available in single-phase, multiphase and hybrid, are based on a rotodynamic pumping principle and use helicon-axial technology. The principle has been developed to add energy to a fluid mixture of water, oil, and gas (i.e., an unprocessed wellstream).
The design is inherently robust and wear-resistant in conditions where particles such as sand may be present, a common occurrence in most production systems. The technology has been developed to handle hydrocarbon flow with gas volume fractions (GVF) of up to 100% mechanically and up to 95% operationally. The pump is capable of generating a differential pressure of up to 2,900 psi [200 bar], depending on the actual GVF at suction conditions.
The design has also been tested and operated with fluid viscosities ranging from 1 cP to 4,000 cP (at startup).
