Abstract:
1. A subsea production system, comprising: a surface host facility comprising a surface electrical power source and a processor based surface controller; a subsea power distribution hub operationally connected to the surface electrical power source to receive a high AC voltage input, the subsea power distribution hub comprising a subsea transformer to step down the high AC voltage input from the surface electrical power source into a medium AC voltage subsea output and a low AC voltage subsea output, wherein the processor based surface controller is operationally connected to the subsea power distribution hub to transmit output data to the subsea power distribution hub and to receive input data from the subsea power distribution hub; an in-well pump disposed in a subsea well, the in-well pump being powered from one of the voltage subsea outputs of the subsea power distribution hub; and a seafloor booster pump being powered from one of the voltage subsea outputs of the subsea power distribution hub; wherein the processor based surface controller is configured to, in response to receiving input data from the subsea power distribution hub, initiate real-time monitoring and response control actions at the surface on the in-well pump.
