Abstract

In at least some embodiments, an electrically controlled subsea production system includes a subsea electrical distributor that receives a high direct current (DC) voltage. The electrical distributor converts the high DC voltage to a lower DC voltage. The electrically controlled subsea production system also includes a plurality of subsea trees coupled to the subsea electrical distributor, wherein valves of the subsea trees selectively operate based on the lower DC voltage.
