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).

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.

Abstract: A device for laying flexible tubular conduits from a floating support comprises rigid accessories the outer dimension of which is greater than the outer diameter of the conduit. It comprises main, linear winch-type tensioning means (6) for normal lowering of the flexible conduit (3) to be laid. The linear winch has an essentially vertical axis and comprises the last means for guiding the flexible conduit at the level of the floating support (1) and auxiliary holding means (19) which hold the flexible conduit by measn of an accessory (21) mounted on the flexible conduit, such as an end fitting or an auxiliary accessory, and enable the main tensioning means (6) to clear a section of flexible conduit on which the accessory (21) is mounted.

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.
