Subsea processing involves manipulating the well stream between downhole of the wellhead and host. Subsea processing applications are hydrocarbon boosting (pumping), separation systems, gas compression, multiphase flowmetering, and produced water and gas reinjection. Prerequisites and enablers for the abovementioned applications are long‐distance/high voltage power, advanced process monitoring and control, cost‐efficient installation, maintenance and modular design for intervention, and retrieval (Eidsmoen, 2011).
