... issues related to the transported fluid such as: pressure drop, liquid hold-up, hydrates, corrosion and sand. The recent subsea technology development, Pseudo Dry Gas System (PDGS), has demonstrated that deep water fields (~2000 m) can be transported long distances (~200 km) to existing processing...

... of the sunken riser. There are, however, serious flaws to this approach, the most apparent being the lack of reliable multiphase flow models for flow in annuli, that is, flow between the inner and the outer pipe. Commercial multiphase flow simulators lack the ability to correctly predict pressure drop...

From these experiments, it was concluded that the flowrate at which loading occurs can be predicted by the overall pressure drop curve...
