Hybrid Pump: A New Type Of Pump For The Pazflor Deep Sea Project
MetadataShow full item record
Subsea processing gives pump engineers permanent technical challenges due to the comprehensive specifications that often stretch the proven limits of technology. It is particularly true for pumps that have to boost a multiphase effluent. This paper presents the state-of-the-art of the centrifugal or multiphase pumps that are designed to be installed on the sea floor. It then describes why the existing technology could not match the technical requirement of a deep sea project for which they development scheme relied on a gas/liquid subsea separation, and pumping of the mixture of liquid and gas carried-under. It finally presents the pump technology specifically developed for this world first full field development application, thy hybrid pump.
