Abstract: A coupling for pipe-in-pipe pipeline tubing formed of an assembly of sections each incorporating an inner pipe and an outer pipe butt welded to the inner pipe, two successive sections being joined together by the welding of respective inner pipes delimiting a segment of inner pipe, wherein it is formed by a sleeve arranged perpendicularly to the segment and a filler material constituted by a quick-set mortar based on aluminous cement and sand, said filler material being arranged in the free space delimited by the sleeve, said segment and the outer pipes of two successive sections.

Abstract: A device for sealing off a segment of pipe-in-pipe pipeline including an inner pipe and an outer pipe between which an insulating material is interposed, and including a water detector. The device includes: a first plug for closing off the inner pipe, a tubular extension welded to the end of the outer pipe, the free end of the extension extending beyond the first plug and being closed off by a second plug, and a means for fixing the position of the inner pipe and outer pipe, integral with the extension.

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.
