<p>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.</p> |
