Abstract: Apparatus and method for operating a subsea compression system is disclosed, the subsea compression system comprising a separator (3), a compressor ( 1) and a pump (2), wherein the compressor is operable for compression and discharge of gas that is separated from a well stream fed into the separator, and the pump is operable for pumping liquid that is separated from the well stream. According to the invention, compressed gas is recycled from the compressor discharge side to the compressor intake side via a turbo-expander unit (10) which is drivingly connected to the pump, the pump operable in response to circulation of compressed gas from the compressor discharge side to the compressor intake side.

Abstract: A compensated motor barrier and pump lubrication fluids pressure regulation system for a subsea motor and pump module is disclosed, comprising a hydraulic fluid supply providing barrier fluid and lubrication fluid to the motor and pump module, a barrier fluid circuit (14, 15, 17) in which the hydraulic fluid is pre- tensioned towards the motor by a pressure applied from a first separating pressure compensator (19), a lubrication fluid circuit (21, 22, 24) in which the hydraulic fluid is pre-tensioned towards the pump by a pressure applied from a second separating pressure compensator (26). The second pressure compensator (26) is responsive to the pumped medium pressure at a suction or at a discharge side of the pump and applies the sum of that pressure and its inherent pre-tensioning pressure to the lubrication fluid circuit, and the first pressure compensator (19) is responsive to the pressure in the lubrication fluid circuit and applies the sum of that pressure and its inherent pre-tensioning pressure to the barrier fluid circuit.
