ABSTRACT:
A slip ring mounted in a buoy is used to transmit power from a generating vessel to an offshore installation. The vessel is moored to the buoy and the slip ring acts as an electric swivel allowing the vessel to weathervane around the buoy as environmental conditions may require. The slip ring conducts high voltage three phase power and an open ring stack allows circulation of high dielectric insulating oil therethrough. The insulating oil allows the ring stack to have smaller dimensions than would be possible if an air dielectric were used. Access ports and viewing windows enable maintenance to be performed on the ring without removing the outer housing.
