Abstract: A heated subsea pipe and process for transporting fluids, includes a plurality of pipe sections each having a transport tube for receiving the fluids, an electrically insulating inner layer arranged around the transport tube, a sealing tube made of electrically conductive material arranged around the electrically insulating inner layer, a thermally insulating outer layer arranged around the sealing tube. The transport tube is electrically connected to the sealing tube at each of the two ends of the pipe. The pipe includes two electrical cables connected to an electric generator and, to the transport tube and to the sealing tube of the pipe at a point situated between the two ends of the pipe to produce two parallel electrical circuits each traversed by an electric current for heating the transport tube of the pipe by Joule effect.
