摘要： A device for filling a ditch in the sea bed to cover a pipe placed therein, including two nozzle assemblies (6, 7) closely spaced from the sea bed on either side of a trench (1) dug therein. The nozzles are pointed at the sea bed and said trench and supplied with pressurised water to be directed continuously into the sea bed on either side of the trench to move material from the sea bed into the trench as the device travels therealong, and thereby at least partially fill said trench. A guide assembly (14) is provided for channeling the flows created by the nozzles (6, 7).

摘要： 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.

摘要： A method for laying tubular conduits on an underwater surface located at a depth P, particularly an ocean bed, by means of at least a first floating support. The method includes the steps of loading onto the first floating support a length of flexible tubular conduit which is greater than depth P; from said support, laying a length of rigid tubular conduit (5) of which the free end is held by said first floating support; connecting a first end of said flexible tubular conduit (15) having a length greater than the water depth P to the free end of said rigid tubular conduit (5); lowering the rigid tubular conduit (5) and the flexible tubular conduit (15); halting the lowering operation once the first end of the flexible tubular conduit connected to the end of the rigid tubular conduit has reached the bottom (7) while a second end of the flexible conduit (15) is still on the first floating support (1).

摘要： A device for temporarily holding a load on a holding line comprises two articulated elements which form a clamp. Each element comprises a jaw and an arm. One of the two arms comprises means for suspension on a holding line. The device can adopt two positions, a first, closed position for holding the held load and a second, open position for releasing the load. The arm constitutes means for amplifying the holding force f exerted between the two arms in the vicinity of their ends to keep the jaws closed while the load is being held. The device comprises releasable means linking the arms for limiting the distance between said arms, exerting said holding force f required to maintain the jaws (11, 21) in the closed first position. The arms (12, 22) are so configured that the means (30, 37) for limiting the distance between the lever arms are arranged laterally at a distance greater than 0.3 metre from the axis of the holding line (32).

摘要： The invention relates to a device for laying flexible tubular conduits comprising insulating sheaths and reinforcements from a floating laying support. It comprises a recoverable flexible tubular handling conduit (8) connected mechanically to the flexible tubular conduit to be laid (17). The flexible tubular handling conduit (8) has sufficient mechanical resistance to resist, on the one hand, the combined action of the highest internal pressure which the flexible tubular conduit to be laid (17) must withstand and the axial tractional effort corresponding to the apparent weight in water of the length of flexible tubular handling conduit (8) suspended between the floating support and the base 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 handling conduit to be laid (17) when the latter is suspended between the floating support and the ocean bottom by means of the flexible tubular handling conduit (8).
