Abstract: The invention concerns a process and a device for laying a subsea pipeline according to the J-lay or S-lay method wherein straight sections are mounted onshore, dried and degassed then closed by plugs. The sections are loaded on a pipe-laying ship, are separated from their plugs before the welding. At the welding of each bulkhead a short pumping is operated to reduce the pressure in the part of the annulus located between the two last bulkheads and then the opening leading to the annulus are sealed.

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.
