    Title of invention
    Machine for the simultaneous and helical laying of cables on the external surface of a unitary fluid transport pipe element
    Invention background
    The present invention relates to the general field of fluid transport pipes for the transfer of hydrocarbons, for example oil and gas, from underwater production wells.
    It relates more precisely to a machine making it possible to deposit in a helix (we also speak of “spiraling”) several cables (for example electric heating cables) simultaneously on the external surface of such conduits.
    There are different types of underwater pipes used for the transport of hydrocarbon fluids, single or double jacket. The invention relates more particularly to pipes with a double jacket of the “Pipe In Pipe” or PIP type, that is to say “pipe in a pipe”, in which an internal steel jacket transports the fluids and a steel outer shell coaxial with the previous one is in contact with the ambient environment, that is to say with water.
    Generally, the jacketed pipes are assembled on the ground in elements of unit length (we speak of unitary elements of pipe or oars), of the order of 10 to 100m depending on the carrying capacity of the laying system. These unit driving elements are then transported to sea on a laying vessel. During installation, they are connected to each other on board the ship and as they are laid at sea.
    Furthermore, it is known to heat double-walled pipes over their entire length by means of a plurality of electrical cables which are wound around the external surface of the internal jacket of the pipes to heat it by the Joule effect. This heating solution, which is called “heat tracing” (or “heat tracing” in English), makes it possible to maintain the fluids of hydrocarbons transported in underwater pipes at a temperature above a critical threshold throughout their journey from the production well up to the surface installation, and thus avoid the formation of hydrate crystals or other solid deposits leading to the creation of plugs capable of blocking the underwater pipe.
    Typically, the electric heating cables are flat cables which are provided with a rubber protection and which are deposited in a helix on the external surface of the internal envelope of each unitary conduit element. In practice, this laying is generally carried out individually for each unitary driving element by unwinding from a fixed station the various electric cables, the internal envelope of the unitary driving element being moved longitudinally through the fixed station. For this purpose, the internal envelope of the unitary conduit element is positioned on a support which moves it longitudinally through the fixed station while making it undergo a rotation around its axis of symmetry to allow the cables to be deposited. on the external surface of the internal envelope with a helical movement.
    This type of helical laying of cables by means of a fixed station through which the unitary pipe element translates has however a certain number of drawbacks. In fact, due to the advance movement of the internal envelope of the unitary driving element which is both longitudinal and rotary, the cables are necessarily deposited on the external surface of the internal envelope with a twisting movement. . However, this torsional stress induced on the cables during their installation is liable to create loops in the cables once the latter have been removed. In addition, the residual torsional accumulation can lead to the formation of knots damaging the cables and peeling them from the external surface of the internal envelope of the pipe. Furthermore, this type of helical installation requires a displacement of the internal pipe of the unitary pipe element which requires a relatively complex mechanism - and therefore expensive - to develop.
    Subject and summary of the invention
    The main object of the present invention is therefore to propose a machine for the helical laying of cables which does not have the aforementioned drawbacks.
    According to the invention, this object is achieved by means of a machine for the simultaneous and helical laying of cables on the external surface of a unitary element for carrying fluids, comprising:
    a rotary frame intended to be centered around an axis of symmetry of the unitary pipe element, the frame supporting a plurality of winding elements intended to receive cables to be laid on the unitary pipe element, the elements of winding each located in a plane substantially longitudinal to the unitary driving element and spaced from one another around the axis of symmetry of the unitary driving element;
    means for adjusting the inclination of each winding element relative to the longitudinal plane in which it is located;
    a linear displacement stepping motor for moving the frame along the unitary driving element; and a rotary displacement stepping motor for pivoting the frame around the axis of symmetry of the unitary driving element.
    The invention thus proposes to simultaneously lay several helical cables from a machine which moves along the unitary pipe element, the latter remaining fixed during the laying process. The machine according to the invention thus has a simplified design compared to a machine having to move the unitary driving element linearly while pivoting it around its axis. In addition, the winding elements being each located in a plane substantially longitudinal to the unitary conduit element, it is possible to lay the cables in a helix on the external surface of the unitary conduit element without exerting stress on them. torsional, which avoids the problems inherent in this type of stress.
    Advantageously, each winding element comprises: a storage coil on which is wound the cable to be laid on the unitary conduit element;
    a reel spool for receiving one end of the cable unwound from the storage spool to bring it to the external surface of the unitary conduit element;
    a guidance system for guiding the unwound cable from the storage reel to the external surface of the unitary conduit member; and a compression system for applying a compression force to the cable coming to rest on the external surface of the unitary pipe element.
    The compression system of each winding element may comprise a telescopic rod, one end of which is fixed to the reel of reel and an opposite end is connected to a roller with interposition of a spring, said roller being able to come to roll on the surface. external of the unitary guide element when laying the cable. In this way, the roller makes it possible to apply a compressive force to the cable coming to settle on the external surface of the unitary pipe element, and thus to improve its fixing.
    Likewise, the guide system of each winding element may comprise a roller device for automatically removing plastic strips covering adhesive strips of the cable before laying said cable on the external surface of the unitary pipe element, and a deflector for guiding the cable from the reel spool to the roller device. The strips of adhesive advantageously make it possible to secure the cable to the external surface of the unitary pipe element. In this case, the roller device may comprise a drive roller intended to receive a free end of the cable coming from the reel of winder and winding rollers on which are intended to wind the plastic strips detached from the cable.
    The storage and reel reels can each be advantageously provided with a braking system. The presence of such a braking system allows, on the one hand to apply a tension during the laying of the cable, and on the other hand to quickly slow down the coils at the end of laying.
    Each winding element can be mounted on one face of the frame by means of a plate capable of pivoting in a radial direction relative to the axis of symmetry of the unitary driving element, the frame further comprising a system. worm gear coupled to each plate to adjust the inclination of each winding element relative to the longitudinal plane in which it is located. In this case, the worm systems are preferably synchronized with each other to allow the same inclination to be given to each winding element.
    The machine may further comprise a carriage supporting the frame by means of a guide ring intended to be centered on the axis of symmetry of the unitary driving element, the carriage being provided with wheels driven by the motor not with no linear displacement step and able to move along a guide rail.
    In this case, the guide ring of the carriage may comprise a toothed wheel which is rotated by the stepping motor of rotary movement. In addition, the carriage may include means for adjusting the vertical position and the horizontal position of the frame, and guide rollers for the unitary driving element.
    Preferably, the machine further comprises optical means for determining the distance between the frame and one end of the unitary pipe element towards which the frame moves. These optical means thus make it possible not only to precisely monitor the progress of the laying of the cables, but also to control the rotary movement of the frame with its linear movement.
    The frame can have a polygon shape with several faces on which the winding elements are mounted.

    Detailed description of the invention
    The invention relates to a machine for simultaneously and helically laying cables on the external surface of a unitary underwater pipe element (hereinafter called "spiraling machine") such as that shown in FIG. 1.
    The cables laid can be electric cables wound around the external surface of the internal envelope of a submarine pipe with double envelope to heat it by Joule effect (in the case of a traced heating) or fiber optic cables wound around the external surface of the internal envelope of a double-envelope submarine pipe to monitor the mechanical deformations applied to them.
    Typically, such cables are flat cables which are provided with a rubber protection and which are covered on one of their faces with two strips of adhesive which make it possible to hold them on this surface, these strips of adhesive being protected by plastic bands.
    In FIG. 1, a unitary pipe element 2 is shown intended, once assembled with other unitary pipe elements, to form the envelope of an underwater pipe (for example the internal envelope of a pipe double jacket), as well as a spiraling machine 4 according to the invention.
    The unitary pipe element 2 is positioned horizontally above the ground, being supported by a plurality of supports 6 (six in number in the figure) regularly spaced from one another.
    As shown in more detail in FIG. 2, the supports 6 are studs which are provided in the lower part 6a with rollers 8 to be moved and in the upper part 6b with a seat 10 of rounded shape on which the unitary element of conduct.
    The height of the seat 10 of these supports 6 can be adjusted, for example by means of a pneumatic cylinder 12. In addition, this seat 10 is preferably provided with elastomer strips 12 to limit crushing of the cables placed on the external surface of the unitary pipe element.
    The spiraling machine 4 according to the invention is doubly mobile relative to the unitary fixed driving element and resting horizontally on the supports 6: it is able to move linearly along the unitary driving element 2, while being able to pivot about an axis of symmetry XX thereof.
    In addition, the spiraling machine 4 according to the invention mainly consists of a rotary frame 14 provided with the proper spiraling means (described later) and a movable carriage 16 supporting the frame (Figure 4).
    As shown in FIG. 3, to move along the unitary driving element, the movable carriage 16 of the spiraling machine is provided with wheels 18 which are driven by a linear displacement stepping motor 20 and which are guided on a rail 22 placed on the ground parallel to the unitary driving element 2.
    Figures 4 to 6 show in more detail the structure of the movable carriage 16 of the spiraling machine according to the invention. This carriage has a lower platform 16a under which the wheels 18 are mounted, as well as a substantially vertical upper platform 16b.
    At its upper platform, the mobile carriage 16 supports the rotary frame 14 by means of a guide ring 24 which is positioned so as to be centered on the axis of symmetry X-X of the unitary driving element.
    At its periphery, the guide ring 24 of the mobile carriage carries a toothed wheel 26 (see FIG. 6) which is also centered on the axis XX and which is rotated by a stepping motor of rotary movement 28. By actuation of the rotary displacement stepping motor 28, the toothed wheel 26 is capable of pivoting about the axis XX, thereby rotating the rotary frame 24 provided with the actual spiraling means around the unitary driving element.
    The guide ring 24 of the mobile carriage also includes a window 30, for example of square shape, intended to be crossed by the unitary driving element during the linear movement of the spiraling machine. Guide rollers 32 positioned inside this window 30 ensure good centering of the unitary driving element during the linear movement of the spiraling machine.
    At its upper platform, the mobile carriage 16 also carries two lasers 36 (Figure 5). These lasers are calibrated to emit an optical beam downstream (relative to the linear movement of the spiraling machine) in the direction of a reflective panel (not shown in the figures) positioned at the end of the unitary driving element. These optical means thus make it possible not only to precisely monitor the progress of the laying of the cables, but also to control the rotary movement of the spiraling machine with its linear movement.
    Furthermore, still at its upper platform 16b, the mobile carriage 16 comprises means for adjusting the vertical position and the horizontal position of the rotary frame 14 of the spiraling machine.
    For example, these means are in the form of rollers 38a arranged vertically and rollers 38b arranged horizontally which make it possible to move in the vertical and horizontal directions the guide ring 24 supporting the rotary frame 14 of the spiraling machine (FIG. 5) . A counterweight system 40 can facilitate the adjustment of the vertical position of the frame.
    Finally, a system of rods 42 connecting the upper platform 16b to the lower platform 16a of the mobile carriage makes it possible to adjust the verticality of the upper platform 16b of the carriage.
    In connection with FIGS. 7 to 14, various characteristics of the rotary frame 14 of the spiraling machine according to the invention will now be described.
    As indicated above, the rotary frame 14 is provided with the actual winding means and is able to pivot around the axis of symmetry X-X of the unitary driving element.
    To this end, the rotary frame comprises a support structure 44 having a polygon shape with a plurality of faces on which are wound winding elements 46. On each face of this polygonal structure is mounted a winding element 46.
    In the example illustrated, the support structure 44 has a nonagon shape with nine faces making it possible to support nine winding elements 46.
    In this exemplary embodiment, it is thus planned to simultaneously lay nine helical cables on the external surface of the unitary pipe element. Of course, depending on the number of cables to be laid, the support structure of the rotary frame could have a different shape.
    The winding elements 46 are intended to receive cables to be laid helically on the unitary pipe element. These winding elements are regularly spaced from each other around the axis of symmetry X-X of the unitary pipe element and are each located in a plane P which is substantially longitudinal to the unitary pipe element.
    More precisely, each winding element 46 comprises in particular a storage reel 48 on which is wound the cable to be laid fitted with its plastic bands, as well as a reel of reel 50 intended to receive one end of the cable unwound from the reel storage to bring it to the outer surface of the unitary driving element, the storage and reel coils of each winding element being aligned in the plane P.
    As shown in FIG. 10, each winding element 46 also comprises a guide system intended to guide the unwound cable from the storage reel 48 to the external surface of the unitary pipe element.
    The guide system of each winding element more precisely comprises a roller device 52 for automatically removing the plastic strips covering the two adhesive strips of the cable before laying the latter on the external surface of the unitary pipe element .
    This roller device 52 is visible in detail in FIG. 12. It consists of a drive roller 54 which is intended to receive a free end of the cable coming from the reel of reel 50 and two winding rollers 56 mounted on a support 58 and on which are intended to wind the two plastic bands which have been detached from the cable.
    These rollers 54, 56 have respective axes of rotation A54, A56 which are parallel (the winding rollers 56 are coaxial). The rollers are also positioned in contact with each other so that the drive roller 54 rotates the two winding rollers 56. In addition, the winding rollers 56 are movable in translation along an axial groove 57.
    As shown in FIG. 13, the winding rollers 56 of this device each have a notch 59 intended to receive one end of a plastic strip (not shown in the figure) to be peeled off from the cable.
    The cable still coated with its two plastic bands passes between the drive roller 54 and the two winding rollers 56 as shown diagrammatically by the arrow F in FIG. 12. A spring 62, one end of which is fixed to the support 58 of the rollers winding 56 keeps them always in contact with the drive roller 54. The end of the plastic bands being anchored in the respective slots 59 of the winding rollers, these bands are wound around the rollers winding as the cable passes between the two rollers 54, 56.
    In addition, as the two plastic bands are wound on the winding rollers 56, the diameter of the latter increases, so that the axis A56 of the winding rollers is offset by translating axially. in the groove 57. The presence of the spring 62 makes it possible to always keep the drive and winding rollers in contact with each other despite this axial translation of the axis of the winding rollers.
    The guide system of each winding element also comprises a deflector 64 for guiding the cable from the reel spool 50 to the roller device 52 previously described, then to the external surface of the unitary conduit element. As shown in FIG. 10, the presence of such a deflector 64 in the form of a funnel ending in a ramp makes it possible in particular to prevent the cable from jamming during its movement from the reel of the reel to the unitary element of conduct.
    According to an advantageous arrangement of the invention illustrated in Figure 11, the storage coils 48 and reel 50 of each winding element are each provided with a braking system.
    The coils 48, 50 which are mounted on a plain bearing (not shown in the figures) are each provided with an adjustable braking band 66 which are fixed at one end by a hook system 68 and connected at the end to a spring system 70. The latter makes it possible to generate a counter-rotating force on the coils (of the order of a few Newton) which, on the one hand, provides a tension force on the cable during its installation, and d 'on the other hand a progressive slowdown of the coils when the cable laying process is stopped.
    As shown in particular in FIGS. 10 and 14, each winding element also comprises a compression system for applying a compression force to the cable coming to rest on the external surface of the unitary conduit element.
    The compression system comprises a telescopic rod 72, one end of which is fixed to the reel of reel 50 and an opposite end is connected to a roller 74 with the interposition of a spring 76. More precisely, the roller 74 is fixed to the end of the rod 72, the latter being able to slide inside a sheath 78, the spring 76 being interposed between the rod and the sheath.
    In this way, the spring 76 makes it possible to apply pressure to the roller to keep the latter in contact with the external surface of the unitary guide element when the cable is laid. Thus, the roller 74 rolls on the external surface of the unitary conductive element and constantly exerts a compressive force on the cable during its installation, regardless of the concentricity defects of the unitary conductive element.
    In addition, the roller 74 can take two positions: a so-called working position in which the spring exerts pressure on the latter when the cable is laid, and a rest position (not shown in the figures) in which the rod 72 carrying the roller is retracted inside the sheath 78 and locked in this position by means of a pin 80.
    According to another advantageous arrangement of the invention, each winding element 46 is mounted on one face of the support structure 44 by means of a plate 82 (see FIGS. 10, 16 and 17) which is able to pivot around a radial axis YY relative to the axis of symmetry XX of the unitary pipe element (see FIG. 15).
    In particular, each winding element 46 is integral with a plate 82 which is fixed to the support structure 44, the storage and reel 50 reels 50 of each winding element being positioned on the side outside the support structure, while the roller device 52 and the compression system protrude from the interior through windows 84 made in the support structure (see Figure 9).
    Furthermore, each plate 82 is coupled for the adjustment of its pivoting around the radial axes Y-Y to a worm screw system 86. By adjusting the pivoting of the plates 82 relative to the radial axes
    Y-Y, the inclination of each winding element 46 is thus adjusted relative to the longitudinal plane P in which it is located. This adjustment makes it possible in particular to limit the torsional effect exerted on the cables by the rotation of the frame of the spiraling machine when they are placed on the external surface of the unitary pipe element.
    Preferably, these worm systems 86 are synchronized with one another to allow the same inclination to be given to each winding element. For this purpose, the endless systems of the spiraling machine are fixed to each other by universal joints 88 (see in particular Figure 16).
    An example of application of the spiraling machine according to the invention to the simultaneous laying of helical cables on the external surface of a unitary pipe element is described below.
    In this example of application, the unitary pipe element has a length of 50 m and it is sought to lay on its external surface nine helical cables, with for example a propeller pitch of 6 m. The propeller pitch is obtained by adjusting the inclination of each winding element 46 relative to the longitudinal plane P in which it is located.
    As shown in FIG. 1, the unitary pipe element 2 is positioned horizontally on the supports 6. For a unitary pipe element having a length of 50 m, there will for example be six supports 6 spaced 10 m apart with a support to each end of the unitary pipe element.
    The spiraling machine 2 is positioned at one of the ends of the unitary conduit element with its rotary frame 14 disposed around the unitary conduit element. The lasers 36 of the spiraling machine are pointed towards the reflecting panel positioned at the other end of the unitary driving element.
    The linear displacement stepper motor 20 and the rotary displacement stepper motor 28 of the spiraling machine are remotely controlled from a work station (not shown in the figures). Using the measurement of the linear advance of the spiraling machine obtained by optical means (lasers 36 and reflective panel), the work station notably makes it possible to synchronize these two motors 20, 28 in order to ensure laying the nine cables with the desired propeller pitch and as a function of the speed of linear movement of the carriage of the spiraling machine. By knowing the progress of the spiraling machine, the workstation adapts the speed of rotation of the rotary frame. In particular, when the rotation is late, the work station imposes a higher rotation speed to catch up (and vice versa).
    Different programming of motors 20, 28 is possible. The stepping motors can be programmed to operate in "speed mode" in which the programmed setpoint is a speed setting point for the machine (for example 5m / min). Stepper motors can also be programmed to operate in "motor torque mode" in which the programmed setpoint is a motor torque setpoint. Stepper motors can also be programmed to operate in "position mode" in which the programmed setpoint is the number of motor steps (for example 5000 steps).
    Once the stepping motors 20, 28 have been programmed at the workstation, the spiraling machine advances linearly towards the opposite end of the unitary driving element with a synchronized rotation of its rotary frame in order to ensure the simultaneous laying of all nine cables in a helix on the external surface of the unitary laying element. The advance of the spiraling machine is stopped automatically by optical means.
    FIG. 18 shows the result of the spiraling with the external surface of the unitary pipe element 2 which has nine cables 90 laid in a helix.
