The Power Buoy, which was developed for a specific early production application, can be used for subsea field control, remote pigging, multiphase pumping, chemical injection, subsea production support, and for the provision or distribution of large-scale power. It provides medium voltage electrical power (3.3 kV) to operate up to eight subsea electric submersible pumps (ESPs) simultaneously in eight discrete subsea wells, transmitting produced oil back to an existing platform facility approximately 8.7 miles (14 km) from the subsea development itself. The power buoy can be used to boost fluid pressure in depleting fields either by powering and controlling remote electric submersible pumps (ESPs) or subsea water injection equipment.
