The implementation of subsea separation and liquid boosting is becoming a common development scheme for the exploration of deep water fields. Subsea separation is an attractive and economic solution to develop deep offshore fields producing fluid without hydrate or wax. Recently the subsea separation system is designed for a water depth of 3,000 m and internal design pressure up to 690 bar. Development and application of subsea separation system are relatively common in the developed countries and many studies have been conducted previously, but it is still a new field in Korea and this is the significance of this study. In this study, gas-liquid mixture flow characteristics inside in-line type subsea separation system are investigated by numerical and experimental studies for the development of subsea separator. For the subsea separator designed in this study, it is predicted to have a separating efficiency of 70%.
