Abstract
A separating system (1) includes a riser (3) for receiving fluid from a multi-phase pipe (2) and for delivering gas to a subsea gas pipeline (8) through a gas delivering pipe (9). A liquid receiving pipe (12) has a lower end (14) with a liquid intake (15) being adapted to receive liquid from a liquid column (6) in the riser. A liquid delivering pipe (16) has an upper end (17) adapted to receive liquid from an upper end (13) of the liquid receiving pipe (12) and a lower end (18) adapted to deliver liquid to a subsea liquid pipeline (19). A level control system (22) controls the level of the surface of the liquid column by regulation of the liquid flow rate to the liquid pipeline. The riser encloses the liquid receiving pipe, the liquid delivering pipe and the gas delivering pipe. A method for separating is furthermore disclosed.
