Abstract: L'invention a pour objet un procédé de pose, sur un fond, notamment un fond marin, de conduites tubulaires utilisant au moins un support flottant. Il comporte les étapes consistant à: - connecter une extrémité d'une conduite tubulaire rigide (5) d'une section de conduite tubulaire flexible (15) d'une longueur supérieure à la profondeur de l'eau; - descendre la conduite tubulaire rigide (5) et la conduite tubulaire flexible (15) sur le fond (7); - arrêter la descente à un instant où l'extrémité de la conduite tubulaire flexible (15) opposée à la conduite tubulaire rigide (5) se trouve encore à bord du support flottant (1).

Abstract: Device for securing a flexible line to a structure, including a hollow rigid member, forming part of the said structure or fixed onto the said structure, and which the flexible line passes through after having been drawn, with the aid of a hauling cable fixed to one end of the said flexible line, particularly onto the end fitting mounted on the latter for its connection to the said structure, and a bend restrictor engaged on the said flexible line and secured to fixing means capable of interacting with fixing means secured to the said hollow rigid member for fitting the bend restrictor onto the said structure. It comprises means (13) for immobilising the bend restrictor (6) on the said flexible line (4) at a distance from the said end of the latter during a first phase of hauling the flexible line, at the end of which phase the bend restrictor is brought level with the opening zone of the said hollow rigid member (3) for the purpose of fitting it, the said hollow rigid member including, at least during the said first hauling phase, a flared mouthpiece (9).

Date Oct. 17, 1991.A device for laying flexible tubular conduits from a floating support is provided. The flexible tubular conduit has insulating sheaths and reinforcements where the conduit includes a recoverable flexible tubular handling conduit connected to the flexible tubular conduit. The flexible tubular handling conduit has sufficient mechanical strength to withstand the combined action of the highest internal pressure and the axial tensile force corresponding to the apparent weight in water of the length of tubular handling conduit which is suspended between the floating support and the floor, and on the other hand, the isolated action of the axial tensile force corresponding to the apparent weight in water of the length of flexible tubular conduit when the latter is suspended between the floating support and the floor by the flexible tubular handling conduit.

Abstract: A device for laying, in a stepped motion, tubular conduits from a floating support comprises a pair of clamps for gripping the tubular conduit. Each clamp can alternately provide a restraining force on the tubular conduit to be laid. The device is characterized in that one of the clamps can move relative to said floating support and is submerged. The mobile clamp (2) is at least partially annular so that the tubular conduit (5, 15) it surrounds can be inserted through it and has a first, closed position on the conduit (5, 15) and a second, open position which allows the mobile clamp (2) to slide along the conduit (5, 15). The device is also characterized in that it comprises means (16, 4) which hold the mobile clamp (2) and support loads on said floating support (1) when the tubular conduit (5, 15) is being laid.

Date Oct. 17, 1991.A method for laying a pipeline formed of joined rigid and flexible tubular conduits on an underwater surface, particularly an ocean bed, by using a floating support. The method includes the steps of: loading onto the floating support a length of flexible tubular conduit; laying from the support a length of rigid tubular conduit; connecting the ends of the two conduits together; lowering the conduits; and halting the lowering when the rigid conduit hits bottom, while the other end of the flexible conduit is still in the floating support.
