Definitions

  • the object of the present invention is to provide a device of this kind intended for the laying or raising of a submarine cable or pipe.
  • This device is characterized in that it comprises a dome mounted upon a dnlm which is rotatable with respect to the dome.
  • the dome may have a central bearing through which the shaft of the floating drum passes.
  • the drum has peripheral members making it possible to cause or to check the rotation of the drum in relation to the dome.
  • FIG. 1 is a view of the device in vertical cross-section along the axis of the drum
  • FIG. 2 is a view of part of FIG. 1 on an enlarged scale
  • FIG. 3 is a schematic plan view of the whole device
  • FIG. 4 is a view of a part of the guide-track of the cable or pipe.
  • a drum 1 in the form of a revolving cylinder having a vertical axis of rotation 13 is provided with a horizontal floor 3 which is securely sealed to the inside wall of the drum 1 along an impervious sealing line 24 on the inner surface of the drum.
  • a plurality of web members 2' are arranged within the drum 1 in diametrical planes forming a supporting truss, which insures the rigidity of the drum 1.
  • the drum 1 is open at the upper portion and as shown in FIGURE 2 is terminated by an annular edge 25 with T-shaped cross-section, and supporting an annular rail 5.
  • Mounted on drum 1 is a dome 7 having a central bearing 14 in which the shaft 13 is adapted to rotate.
  • the diametrical cross-section of the lower edge 26 of the dome is in the shape of an inverted U.
  • a certain number of rollers 6 are mounted, adapted to run on the rail 5.
  • a vertical annular toothed rack 9 is supported by a horizontal ring 27 inserted between the edge 25 of the drum 1 and the rail 5. Toothed rollers 10 mounted along with the rollers 6 are adapted to mesh with this rack.
  • a mechanical or electrical device 11 arranged entirely on the floor of the dome 7 makes it possible to exert either a driving force or a braking force on the toothed rollers 10, and consequently to cause the drum 1 to rotate in relation to the dome 7 or on the other hand to check its rotation.
  • a plurality of fins 12 are fixed on the drum 1, below the line of the water, and are capable of'being oriented so as to co-operate in the braking of the rotation of the drum. These fins could be wholly or partially replaced by propellers with axes tangential to the drum, making it possible to exert on the latter a torque or braking ac tion.
  • a plurality of rollers 8 are fixed on the outer walls of the dome 7 in rolling engagement against the core of the rail 5 so as to prevent the dome 7 from rising above the drum 1, and also, with the shaft 13,. to contribute to the good centering of the drum 1 in relation to the dome 7.
  • the toothed rack 9 could also be arranged outside and not, as shown, inside the rail 5.
  • the shaft 13 and the bearing 14 could if necessary be eliminated.
  • a caterpillar drive 15 is situated on the floor 15, and through this caterpillar drive the cable 4, to be laid or raised, is passed. It can be actuated so as to co-operate with.the toothed rollers 10 in the driving or, vice versa, braking of the cable.
  • the cable 4 passes on an articulated track 19 fixed to the dome.
  • the drum 1 rotates clockwise due to the force exerted on the coiled cable by the weight of the cable already laid. Its rotation would cause the rotation of the dome 7 if the latter were not held; however, the dome 7 is secured to and is kept at a constant distance from the tug boat by a first rope 34 going from a point 36 belonging to the ship, to a fixed point 17 of the dome and is kept stretched by the displacement of the point 35 in a direction opposite to that of the drum 1.
  • a second rope 35 runs from the point 36 to the point 18 on the dome, and prevents the latter from rotating.
  • FIG. 4 is a schematic representation of the guide track of the cable.
  • This track consists of articulated elements 20 each carrying on its top surface live rollers 22 over which the cable passes, and, in the vicinity of the two ends of its lower surface, stops 21, which prevent the radius of curvature of the guide track from falling below a minimum radius, in practice the minimum radius of coiling in the drum 1.
  • Closed floats 23 are arranged below the water-line, and intowhich more or less water can be admitted according to the weight of the cable to be laid. When laying takes place'in shallow Water, the cable, in striking on the sea bed, only drags a few floats below the level of the water, and the guide track consequently remains horizontal over nearly its entire length.
  • drum 1 and dome 7 are towed by a tugboat or similar vessel in a direction indicated by rope 34 in FIG- URE 3.
  • Motor 11 is actuated to rotate drum 1 clockwise so that cable 4 unwinds itself onto guide track 19 and is progressively immersed beneath the surface of the water and laid upon the ocean bed.
  • the traction exterted by cable 4 is also eilective to turn drum 1 clockwise.
  • Rope 35 prevents dome 7 from turning clockwise along with drum 1 and dome 7 does not rotate.
  • the rotation of drum 1 may be braked either by means of opening fins 12 to impede rotation, or by slowing down motor 11.
  • fins 12 are closed against the surface of drum 1 so that they cease to cause turbulence and impede rotation, and motor 11 is actuated to cause counterclockwise rotation of drum 1 so that the cable will be lifted up and coiled within the drum upon floor 3.
  • Apparatus for laying or raising a submarine cable or the like comprising a floating drum having means for Patented Apr. 28, 1966 supporting a cable in coiled form therein, a dome provided with means to allow passage of the cable, said dome being rotatably supported on said drum so as to permit rotation of said drum relative to said dome about a vertical axis, means connected to said dome for preventing rotation thereof, means in said apparatus for causing relative rotation between said dome and said drum, and means for regulating the rate of rotation of said drum relative to said dome.
  • Apparatus as defined in claim 1, wherein said means to regulate the rate of rotation of said drum include a plurality of water-engaging adjustable fins disposed around the periphery of said drum.
  • said supporting means further comprises a central vertical shaft secured'to said drum and received within bearing means secured to said dome.
  • Apparatus as defined in claim 3, wherein said means to regulate the rotation of said drum include a toothed annular rack positioned adjacent to said guide rail means and motor driven toothed rollers cooperating with said rack.
  • Apparatus for laying a submarine cable or the like comprising a rotatable essentially annular drum capable of floating in water, an essentially annular dome freely rotatably mounted on said drum for rotation of said drum about a vertical axis and provided with means to receive and allow passage of the cable therethrough, means within said drum for supporting the cable in the form of a coil, cable driving means operatively connected with said dome for driving said cable out of said drum through the means in said dome, means connected with said dome for preventing rotation of said dome, and means in said apparatus for regulating the rate of rotation of said drum to vary the rate at which said cable is laid.
