Abstract (en)
A method and system are disclosed for subsea processing multiphase well effluents comprising natural gas and liquid from a subsea hydrocarbon containing formation, which system (1) comprises: - a fluid separation vessel (6) which is connected to a downstream end of a multiphase well effluent transportation conduit (7); - a liquid level transmitter assembly (21,22) for monitoring the gas liquid interface (23) in the fluid separation vessel (6); - a liquid enriched fluid transportation flowline (14) connected at or near the bottom (13) of the fluid separation vessel (6) and a gas enriched fluid transportation flowline (12) connected at or near a top (11) of the fluid separation vessel (6); - a pump (17) connected to an electric motor (18); and - a fast acting variable speed drive system, which is coupled to the liquid level controller which adjusts the pump and motor speed setpoint within 2 seconds to maintain the liquid level in the vessel at a predetermined setpoint.
