摘要： 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.

摘要： A method for assembling pipe-in-pipe pipeline elements for transporting fluids, with each pipeline element comprising an inner pipe including a bulge at one end, and an outer pipe including a recess at one end. The method comprises the successive steps: inserting a first locking wedge axially abutting the bulge of its inner pipe and a corresponding end of its outer pipe, butt-assembling the inner pipe of a new pipeline element on the inner pipe of the pipeline, positioning the outer pipe of the new pipeline element alongside the outer pipe of the pipeline, and butt-assembling the outer pipe of the new pipeline element on the outer pipe of the pipeline by inserting a second locking wedge axially abutting against the bulge of the inner pipe of the pipeline at its free end and the recess of the outer pipe at a corresponding end thereof.

摘要： A method and system for Direct Electrical Heating of a Pipe-In-Pipe pipeline for transporting fluids includes mechanically connecting the steel inner shell to the steel outer shell at different intervals of the pipeline, establishing an electrical and thermal insulation between the inner shell and the outer shell, applying an alternating electric current between an outer surface of the inner shell and an inner surface of the outer shell over the entire length of the pipeline so as to heat the inner shell of the pipeline by Joule effect, and placing on the outer surface of the inner shell at least one layer made of resistive and ferromagnetic material so as to increase the ratio of electric power transmitted to the inner shell.

摘要： A facility for the subsea disposal of the water produced during deepwater hydrocarbon production, includes a subsea oil/water separation station fed with fluids coming directly from at least one hydrocarbon production well, operating at a pressure independent of and lower than the ambient pressure, and comprising an oil outlet for connecting to a production unit and a water outlet, a flat gravity oil/water separation tank resting on the seabed, continuously fed with water leaving the oil/water separation station, operating at a pressure substantially equal to the ambient pressure, and comprising an oil outlet for connecting to the production unit and a water outlet, and a subsea high-pressure pump connected to the water outlet of the oil/water separation station and to a water inlet of the tank to raise the pressure of the water leaving the oil/water separation station to the ambient pressure before it is admitted into the tank.

摘要： 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.

摘要： A method for determining the linear electrical resistance in AC mode of a steel pipeline, including the steps of generating in a portion of the pipeline an induced current by means of an induction coil centered on a longitudinal axis of the pipeline and traversed by an AC current. The coil is housed in a yoke made of ferromagnetic material in order to confine the magnetic field to a predefined surface of the pipeline portion, measuring the active power dissipated by the pipeline portion subjected to the magnetic field, measuring the amplitude of the produced magnetic field, and determining the linear electrical resistance in AC mode of the pipeline portion from the measurements of the dissipated active power and the amplitude of the induced magnetic field. A device is provided for implementing such a method.

摘要： 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.

摘要： A pipe for transporting fluids with control of the buckling of the internal anti-corrosion liner includes a steel tube intended to receive a flow of fluids to be transported, and an annular protective lining made of polymer material, inserted in an interference fit inside the tube against an inner surface thereof and intended to ensure protection of the steel against corrosion of the fluids to be transported, the protective lining having, in a cross-section plane, at least a weakened angular portion whose mechanical resistance to radial deformation is lower than that of the remaining angular portion of the protective lining so as to control the angular location and to promote the axial propagation of buckling of the protective lining following a depressurization of the pipeline.
