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: An inductive coupler connector arrangement for transferring electrical energy between a first connector part to a second connector part. The first and second connector parts have respective ones of first and second magnetic core limbs of which at least one limb carrying a respective electrical winding and respective mating means adapted to provide at mating of said first and second connector parts a juxtaposition of abutting faces of respective ends of said respective ones of first and second magnetic core limbs. A gap between the coupler halves is filled with ferrofluid in the form of a deformable pad or tablet or a fat, grease or paste containing magnetic particles, in order to improve the magnetic coupling between said ends of said first and second magnetic core limbs.

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.
