description 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.
