Abstract: The invention relates to a segment of pipe-in-pipe pipeline comprising an annulus under reduced pressure sealed and delimited by a metallic internal pipe inserted into a metallic external pipe and provided with a measurement system to determine in a non-intrusive manner the state of the annulus, the measurement system being composed of a first internal emitter/receiver assembly placed inside the annulus and cooperating with means to measure a first physical quantity such as pressure, hygrometry or temperature inside the reduced pressure annulus and a second external emitter/receiver assembly arranged to the exterior of the segment and facing said first assembly.

Abstract: The invention relates to a method of manufacturing a pipe segment for a link tube between the sea floor and a petroleum drilling rig disposed on the sea surface, wherein it consists in: providing a transport pipe segment that is resistant to open-sea conditions; disposing a female bayonet-piece around one reinforced end of the transport pipe segment; welding or otherwise bonding a narrower portion of the bayonet-piece to said reinforced end; disposing an insulator around the transport pipe segment and around the bayonet-piece; inserting the transport pipe segment into an outer wall segment; welding or otherwise bonding a narrower portion of the outer wall segment to the other reinforced end of the transport pipe segment; disposing a cover-piece around the bayonet-piece; welding or otherwise bonding the cover-piece to the outer wall segment and to the bayonet-piece; it being possible to apply tightening torque to the outer wall segment and to transmit it to the transport pipe segment.

Abstract: A segment is fitted by screw-fastening for implementing a fluid transport pipe for transporting a fluid, the pipe including an inner wall and an outer wall, the segment including an inner tube and an outer tube that define an annular space between them. The segment includes in particular one heating duct placed in its annular space and opening out at either end of its annular space, the annular space being designed to be closed hermetically in order to enable it to be brought to a reduced pressure. A method of manufacturing the segment and a method of implementing the fluid transport pipe is described.

Abstract: A method of commissioning one subsea hydrocarbon well terminating by a wellhead, wherein, from a petroleum drilling rig, the method includes: screwing double-walled pipe segments together in mutual succession to form a thermally insulated floor-to-surface 1 hydrocarbons, and an outer pipe, between which pipes a thermally insulating material is disposed; connecting the floor-to-surface link pipe to wellhead; and extracting the hydrocarbons via the floor-to-surface link pipe to the drilling rig on the surface.
