Abstract: A method of processing a multiphase well effluent mixture comprises: transferring the multiphase well effluent mixture (G+L) via a multiphase well effluent flowline (3, 23) to a gas liquid separator (5, 24) in which the multiphase well effluent mixture is separated into substantially gaseous and liquid fractions; transferring the substantially liquid fraction L into a liquid flowline (7, 25) in which a liquid pump (8, 29) is arranged; transferring the substantially gaseous fraction into a gas flowline (6, 26) in which a gas compressor (10, 30) is arranged; protecting the gas compressor (10, 30) against pressure and/or liquid surges by recirculating a recycled gas stream (Ghot) via a gas recycling conduit (14, 44) through the gas compressor in response to detection of a pressure and/or liquid surge in the multiphase well effluent mixture; cooling the recycled gas stream by injecting cooled recycled liquid (Lcold) from the liquid flowline (7, 25) into the recycled gas stream (Ghot) which recycled liquid is cool

Abstract: The present invention relates to a flow divider promoting separation, the flow divider comprising an inlet, at least one dividing fin, and two or more outlets. According to the present invention a pipeline leading to the inlet is sufficiently long to promote at least a degree of separation of a fluid that is carried through the pipeline and that initially is mixed, the lighter constituents flowing through a top section of the pipeline, and the heavier constituents flowing through a bottom section of the pipeline, wherein the at least one dividing fin is/are arranged either vertically and/or horizontally in order to divide the flow into two or more smaller flow streams downstream of the flow divider.

Abstract: A lightweight underwater cooling assembly with a high cooling capacity comprises: an assembly of heat exchanger tubes (4) arranged in a submerged refrigerant boiling chamber (5); a thin walled water cooled condenser (6) in which refrigerant vaporized in the boiling chamber (5) is condensed and from which condensed refrigerant is recirculated into the boiling chamber (5); and a thin walled pressure compensating membrane (9) which maintains the fluid pressure (˜psea) within the boiling chamber (5) and condenser (6) substantially similar to the fluid pressure (psea) of the (sea) water surrounding the submerged refrigerant boiling chamber (5).

Abstract: The present invention relates to an all electric subsea boosting system for well fluid boosting by compressing hydrocarbon gases and/or pumping hydrocarbon liquids where said system comprises one or more subsea boosting stations and one or more long step-out power supplies.

Abstract: The present invention relates to a flow divider (1) promoting separation, said flow divider (1) comprising an inlet (2), at least one dividing fin (3), and two or more outlets (4, 5). According to the present invention a pipeline (7) leading to the inlet (2) is sufficiently long to promote at least a degree of separation of a fluid that is carried through the pipeline (7) and that initially is mixed (6), the lighter constituents flowing through a top section of the pipeline (7), and the heavier constituents flowing through a bottom section of the pipeline (7), wherein the at least one dividing fin (3) is/are arranged either vertically and/or horizontally in order to divide the flow into two or more smaller flow streams downstream of the flow divider (1).
