Workshop III -High Differential Pressure Requirements In Multiphase Service

Thursday, 25. Mar 2010

Requirements on subsea multiphase pumps to provide very high differential pressures due to very long tie back distances is increasing. The background for this requirement and alternatives will be evaluated. The influence on the multiphase boosting process and consequences on rotors and efficiency will be discussed, latest research results on materials and rotor design will be presented.

Serial installation of multiphase pumps as well as the possibility of developing hybrid-pumps are options to fullfill the high differential pressure requirement.
