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.

Abstract: A subsea installation for heating a multiphase effluent circulating inside a subsea shell, includes at least one pipeline section disposed along a vertical direction and has an inner tube, an outer tube disposed around the inner tube while being coaxial therewith, a thermal insulation layer, and a system for heating by induction the outer tube. The outer tube has at a lower end an intake aperture to allow circulation of the multiphase effluent from bottom to top in an annular space delimited between the outer tube and the inner tube. The inner tube opening is at an upper end inside the outer tube and emerges at a lower end towards a discharge outlet for the multiphase effluent to allow counter-current circulation of the multiphase effluent from top to bottom inside the inner tube.

Abstract: A multiphase fluid manifold comprises a cylindrical enclosure having, at one longitudinal end, an inlet orifice and, at an opposite longitudinal end, a plurality of cylindrical outlet orifices of the same right section that are regularly distributed around a longitudinal axis of the enclosure and that are aligned in a common plane extending transversely to the enclosure, each of the inlet and outlet orifices leading to or from the inside of the enclosure along a direction that is substantially tangential to the enclosure.
