14.45 - 15.15 Qualification of a novel deepwater gas/liquid separator

The implementation of subsea boosting and processing systems is becoming a common development scheme for the development of deep and ultra-deep water fields. Those subsea processing systems shall address the mechanical and functional constraints that are imposed by the
deepwater installation and operation along with the obvious reliability requirements. Saipem has developed a deepwater gas separation and liquid boosting system that
encompasses a good flexibility in handling a wide range of steady and unsteady multiphase input streams and a relatively simple mechanical arrangement. The system is composed of an array of vertical pipes that contributes in providing the required separation and liquid hold up
volumes. The reduced diameter and wall thickness of the vertical pipes, as compared with the equivalent single
separation vessel, is particularly suited in deep and ultra-deep water applications and/or high pressure services. Furthermore, the system relies on the gravity separation whose efficiency is ensured by its ability to accommodate large variety of input flowrate and un-steady regimes. In the continuous effort of providing reliable and proven process solutions to the market, Saipem has undertaken a
qualification program focused to characterise and demonstrate the system versatility and separation performances, that will involve model testing in multiphase conditions.
