    摘要： Apparatus and method for operating a subsea compression system. The subsea compression system comprising a separator, a compressor and a pump, 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. The compressed gas is recycled from the compressor discharge side to the compressor intake side via a turbo-expander unit 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.

    摘要： A compensated barrier and lubrication fluids pressure regulation system for a subsea motor and pump module is disclosed. The system comprises a hydraulic fluid supply, a barrier fluid circuit, and a lubrication fluid circuit. Hydraulic fluid in the barrier fluid circuit is pre-tensioned towards a motor by a first separating pressure compensator which is responsive to the pressure in the lubrication fluid circuit and which applies the sum of the pressure in the lubrication fluid circuit and an inherent pre-tensioning pressure to the barrier fluid circuit. Hydraulic fluid in the lubrication fluid circuit is pre-tensioned towards a pump by a second separating pressure compensator which is responsive to a pumped medium pressure at a suction side or at a discharge side of the pump and which applies the sum of the pumped medium pressure and an inherent pre-tensioning pressure to the lubrication fluid circuit.
