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

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.
