Un tel dispositif est utilisé notamment pour enrouler des lignes flexibles sur une bobine de stockage et/ou pour dérouler ces lignes flexibles à partir de la bobine de stockage. Les lignes flexibles sont destinées à être disposées sur le fond d’une étendue d’eau, en particulier sur le fond de la mer.  Such a device is used in particular for winding flexible lines on a storage reel and / or for unrolling these flexible lines from the storage reel. The flexible lines are intended to be arranged on the bottom of an expanse of water, in particular on the bottom of the sea.
La ligne flexible est notamment une conduite flexible telle que décrite par exemple dans les documents normatifs API 17J (Spécification for Unbonded Flexible Pipe) 4ème Edition, Mai 2014, API RP 17B (Recommended Practice for Flexible Pipe) 5ème Edition Mai 2014, et API 16C (Choke and Kill Equipment) 2ème Edition, Mars 2015, établis par l’American Petroleum Institute. Plus généralement, la ligne flexible est un ombilical, tel que décrit dans le document normatif publié par l’American Petroleum Institute (API), API 17E « Spécification for Subsea Umbilicals » 5ème Edition, Juillet 2017. The flexible line is in particular a flexible pipe as described for example in standard documents API 17J (Specification for Unbonded Flexible Pipe) 4 th Edition, May 2014, API RP 17B (Recommended Practice for Flexible Pipe) 5th Edition May 2014, and API 16C (Choke and Kill Equipment) 2nd Edition, March 2015, prepared by the American Petroleum Institute. More generally, the flexible line is an umbilical, as described in the normative document published by the American Petroleum Institute (API) API 17E "Specification for Subsea umbilicals," 5th Edition, July 2017.
En outre, sont également considérés comme lignes flexibles, les câbles sous- marins de transport d’énergie ou de télécommunications.  In addition, also considered as flexible lines, submarine cables for transporting energy or telecommunications.
Sont également considérées comme lignes flexibles, les conduites réalisées à partir d’un matériau composite comportant une matrice thermoplastique renforcée avec des fibres communément appelées « Thermoplastic Composite Pipe » (TCP) telles que décrites dans le document normatif DNVGL-RP-F1 19, « Recommended Practice - Thermoplastic composite pipes », publié en décembre 2015 par le DNV GL (Det Norske Veritas GL), les conduites réalisées à partir d’un matériau composite comportant une matrice thermodurcissable renforcée avec des fibres, ou encore les conduites flexibles dites hybrides qui présentent une structure intermédiaire entre celle des conduites flexibles TCP et celles des conduites flexibles de type non lié.  Also considered as flexible lines, the pipes made from a composite material comprising a thermoplastic matrix reinforced with fibers commonly called "Thermoplastic Composite Pipe" (TCP) as described in the normative document DNVGL-RP-F1 19, " Recommended Practice - Thermoplastic composite pipes ", published in December 2015 by the DNV GL (Det Norske Veritas GL), pipes made from a composite material comprising a thermosetting matrix reinforced with fibers, or the so-called hybrid flexible pipes which have an intermediate structure between that of flexible pipes TCP and those of flexible pipes of unbound type.
Aussi, le dispositif selon l’invention est utilisable pour l’enroulement et/ou le déroulement de conduites rigides telles que décrites par exemple dans le document normatif DNV OS-F101 (Submarine Pipeline Systems) Edition d’Octobre 2013, établi par le Det Norske Veritas (DNV). La bobine de stockage comprend usuellement un fût cylindrique flanqué de deux flasques permettant de retenir latéralement la conduite flexible enroulée autour du fût. Les flasques présentent respectivement, une jante et à l’intérieur, un moyeu concentrique, les deux étant reliés ensemble par des rayons. Les flasques forment les faces latérales de la bobine de stockage. Des exemples de bobines de stockage sont décrits dans les documents FR 2 914 290, FR 2 866 018 et FR 2 980 785. Also, the device according to the invention can be used for the winding and / or unwinding of rigid pipes such as described for example in the normative document DNV OS-F101 (Submarine Pipeline Systems) Edition of October 2013, established by the Det Norske Veritas (DNV). The storage coil usually comprises a cylindrical barrel flanked by two flanges for laterally retaining the flexible pipe wrapped around the barrel. The flanges respectively have a rim and inside, a concentric hub, the two being connected together by spokes. The flanges form the side faces of the storage spool. Examples of storage coils are described in documents FR 2 914 290, FR 2 866 018 and FR 2 980 785.
Les lignes flexibles sont déroulées et introduites dans l’étendue d’eau à partir de bobines présentes sur le pont d’un bateau de pose. Il est possible sur ces bateaux de disposer deux rangs de bobines en parallèle l’un par rapport à l’autre.  The flexible lines are unwound and introduced into the body of water from reels on the deck of a laying boat. It is possible on these boats to have two rows of coils in parallel with each other.
Dans ce cas, un premier rang de bobines est disposé entre un premier rail latéral et un rail central, et un deuxième rang de bobines est disposé entre le rail central et un deuxième rail.  In this case, a first row of coils is disposed between a first side rail and a central rail, and a second row of coils is disposed between the central rail and a second rail.
Les bobines sont typiquement disposées sur des supports aussi dénommés berceaux, soudés au pont du bateau de pose afin de maintenir en place les bobines lors de leur transport.  The reels are typically arranged on supports also called cradles, welded to the deck of the laying boat to keep the reels in place during transport.
Pour enrouler et/ou dérouler les lignes flexibles sur les bobines disposées sur deux rangs parallèles, un dispositif d’entrainement en rotation de bobines est disposé sur le rail central.  In order to wind and / or unwind the flexible lines on the coils arranged in two parallel rows, a device for rotating coils is arranged on the central rail.
Le dispositif d’entrainement comporte une première roue d’entrainement dirigée vers le premier rang de bobines pour s’engager avec les bobines du premier rang, et une deuxième roue d’entrainement dirigée vers le deuxième rang de bobines pour s’engager avec les bobines du deuxième rang. La première roue d’entrainement est entraînée par au moins un moteur, et la deuxième roue d’entrainement est entraînée par la première roue d’entrainement via un couplage avec celle-ci, par l’intermédiaire d’un système comprenant un arbre de transmission coopérant avec un moyeu.  The training device includes a first drive wheel directed to the first row of reels for engagement with the first row reels, and a second drive wheel directed to the second row of reels to engage with the first row reels. coils of the second row. The first drive wheel is driven by at least one motor, and the second drive wheel is driven by the first drive wheel via a coupling therewith, via a system comprising a drive shaft. transmission cooperating with a hub.
En fonctionnement, lorsqu’on souhaite enrouler et/ou dérouler une ligne flexible portée par une première bobine sur le premier rang de bobines, on engage la première roue d’entrainement avec la première bobine, de sorte que la première bobine soit entraînée en rotation. Puis, pour enrouler et/ou dérouler une ligne flexible portée par une deuxième bobine sur le deuxième rang de bobines, on engage la deuxième roue d’entrainement avec la deuxième bobine.  In operation, when it is desired to wind and / or unwind a flexible line carried by a first spool on the first row of spools, the first drive wheel is engaged with the first spool, so that the first spool is rotated. . Then, to wind and / or unwind a flexible line carried by a second coil on the second row of coils, the second drive wheel is engaged with the second coil.
La deuxième roue d’entrainement, menée par la première roue d’entrainement, entraîne alors en rotation la deuxième bobine.  The second drive wheel, driven by the first drive wheel, then rotates the second coil.
Cependant, ce dispositif ne donne cependant pas entière satisfaction.  However, this device does not give complete satisfaction.
En effet, le transfert de couple de la première roue d’entrainement à la deuxième roue d’entrainement n'est pas toujours fiable. Pour transférer le couple de manière plus efficace et pour renforcer des accouplements mécaniques, il est nécessaire d’employer des solutions technologiques de transmission de couple onéreuses. Il est connu d’usiner l'arbre de transmission portant les deux roues d’entrainement. L’usinage comprend par exemple la création de cannelures ou encore de dentelures sur toute la longueur de l’arbre de transmission. Ce type d’usinage augmente le coût de fabrication comparativement à une transmission arbre-moyeu à liaisons par goupilles ou à liaisons par clavettes. Indeed, the transfer of torque from the first drive wheel to the second drive wheel is not always reliable. To transfer the couple more In order to reinforce mechanical couplings, it is necessary to employ expensive torque transmission technology solutions. It is known to machine the transmission shaft carrying the two drive wheels. The machining includes for example the creation of grooves or serrations along the entire length of the drive shaft. This type of machining increases the cost of manufacture compared to a shaft-hub transmission pin or key links.
En outre, la configuration à double roues d’entrainement rend difficile l’accès aux moteurs d’entrainement lors des entretiens techniques. En effet, la deuxième roue d’entrainement masque l'accès aux moteurs, et il est nécessaire de la démonter pour accéder aux moteurs.  In addition, the configuration with double drive wheels makes it difficult to access the drive motors during technical interviews. Indeed, the second drive wheel masks access to the motors, and it is necessary to disassemble to access the motors.
Un but de la présente invention est de rendre plus fiable l’entrainement sélectif de bobines situées sur un premier rang et un deuxième rang de bobines par un dispositif d’entrainement commun, tout en simplifiant la maintenance du dispositif.  An object of the present invention is to make more reliable the selective drive of coils located on a first row and a second row of coils by a common drive device, while simplifying the maintenance of the device.

Dans tout ce qui suit, les termes « longitudinal » et « transversal » s’entendent par rapport au sens normal d’allongement d’un navire de pose, c’est-à-dire, s’étendent respectivement dans la direction reliant la proue à la poupe et dans la direction reliant bâbord à tribord. Le terme « vertical » s’entend par une direction orthogonale aux directions longitudinale et transversale.  In all that follows, the terms "longitudinal" and "transverse" refer to the normal direction of elongation of a laying ship, that is to say, extend respectively in the direction connecting the bow to stern and in the direction connecting port to starboard. The term "vertical" means a direction orthogonal to the longitudinal and transverse directions.
Un premier navire de pose 6 d’au moins une ligne flexible 8 est illustré partiellement sur les figures 1 et 2.

L’assemblé peut également comprendre au moins un câble pour transporter une puissance électrique ou une information entre le fond et la surface de l’étendue d’eau. Aussi, l’assemblé peut comporter au moins un tuyau pour transporter une puissance hydraulique ou encore un fluide de service pour permettre une remise en production aisée de la conduite flexible après un long arrêt. Enfin, l’assemblé peut également comprendre des éléments de renfort mécanique (ou « fillers » en anglais) propres à transmettre les efforts radiaux. In a variant, the flexible pipe is an integrated production bundle, comprising a central core formed by a standard flexible pipe structure of the type defined above by the normative documents and an assembly comprising at least one tube. , a cable or pipe, wrapped around the central core. The main function of the assembly is to provide active heating to the hydrocarbon fluid circulating in the central core. For example, said at least one tube allows the transport of a thermally controlled fluid. Alternatively, said at least one tube allows gas drainage. The assembly may also include at least one cable for carrying electrical power or information between the bottom and the surface of the body of water. Also, the assembly may comprise at least one pipe for transporting hydraulic power or a service fluid to allow a return to production of the flexible pipe easy after a long stop. Finally, the assembly may also include mechanical reinforcing elements (or "fillers" in English) suitable for transmitting the radial forces.
Plus généralement, la ligne flexible est un ombilical, tel que décrit dans le document normatif publié par l’American Petroleum Institute (API), API17E « Spécification for Subsea Umbilicals ».  More generally, the flexible line is an umbilical, as described in the normative document published by the American Petroleum Institute (API), API17E "Specification for Subsea Umbilicals".

The first tower 14 comprises a first wheel 29 adapted to cooperate with the face 26 of the first coil 24, and a vertical displacement assembly (Not shown in the figures) of the first tower 14 own to move the first wheel 29 in the vertical direction.
Le premier rail 16 s’étend sensiblement suivant la direction longitudinale du navire de pose 6. La première tour 14 est montée mobile sur le premier rail 16 suivant la direction horizontale, le déplacement de la première tour 14 étant guidé par le premier rail 16. Par « sensiblement suivant la direction longitudinale », on entend par exemple que le premier rail 16 s’étend suivant la direction longitudinale ou inclinée par rapport à la direction longitudinale d’un angle inférieur à 60°. The first rail 16 extends substantially in the longitudinal direction of the laying ship 6. The first tower 14 is movably mounted on the first rail 16 in the horizontal direction, the displacement of the first tower 14 being guided by the first rail 16. "Substantially in the longitudinal direction" means for example that the first rail 16 extends in the longitudinal direction or inclined relative to the longitudinal direction by an angle less than 60 °.
De manière similaire, la deuxième tour 18 est configurée pour guider en rotation une deuxième bobine de stockage 30 de ligne flexible 8. La deuxième bobine 30 comporte une face 32 en regard de la deuxième tour 18 et une face opposée 34. La deuxième tour 18 comporte une deuxième roue 35 propre à coopérer avec la face 32 de la deuxième bobine 30, et un ensemble de déplacement vertical (non-représenté sur les figures) de la deuxième tour 18 propre à déplacer la deuxième roue 35 dans la direction verticale.  Similarly, the second tower 18 is configured to rotate a second flexible line storage coil 8.

The second tower 18 has a second wheel 35 adapted to cooperate with the face 32 of the second coil 30, and a vertical displacement assembly (not shown in the figures) of the second tower 18 adapted to move the second wheel 35 in the vertical direction.
Le deuxième rail 20 s’étend également sensiblement suivant la direction longitudinale. La deuxième tour 18 est montée mobile sur le deuxième rail 20 suivant la direction horizontale, le déplacement de la deuxième tour 18 étant guidé par le deuxième rail 20.  The second rail 20 also extends substantially in the longitudinal direction. The second tower 18 is movably mounted on the second rail 20 in the horizontal direction, the displacement of the second tower 18 being guided by the second rail 20.
Le dispositif d’entrainement 22 est destiné à être placé entre les première et deuxième bobines 24, 30. Il est destiné à coopérer sélectivement avec chaque bobine 24, 30 pour entraîner en rotation la bobine 24, 30 autour d’un axe de rotation horizontal A-A’.  The drive device 22 is intended to be placed between the first and second coils 24, 30. It is intended to cooperate selectively with each coil 24, 30 to rotate the coil 24, 30 about a horizontal axis of rotation. A-A '.
En référence aux figures 3 à 7, le dispositif d’entrainement 22 comprend une tour centrale 40 comportant un châssis 42, un support 44 porté par le châssis 42, le support 44 étant monté pivotant sur le châssis 42 autour d’un axe de pivotement B-B’ entre une première position pour l’engagement sur la première bobine 24 et une deuxième position pour l’engagement sur la deuxième bobine 30.  Referring to Figures 3 to 7, the drive device 22 comprises a central tower 40 having a frame 42, a support 44 carried by the frame 42, the support 44 being pivotally mounted on the frame 42 about a pivot axis B-B 'between a first position for engagement on the first coil 24 and a second position for engagement on the second coil 30.
Le dispositif d’entrainement 22 comprend également un mécanisme actif de pivotement 46 du support 44 (visible sur la figure 8) et un mécanisme de déplacement 48 de la tour centrale 40.  The driving device 22 also comprises an active pivoting mechanism 46 of the support 44 (visible in FIG. 8) and a movement mechanism 48 of the central tower 40.
La tour centrale 40 est propre à se positionner transversalement entre la première tour de guidage 14 et la deuxième tour de guidage 18, comme représenté sur les figures 1 et 2.  The central tower 40 is adapted to be positioned transversely between the first guide tower 14 and the second guide tower 18, as shown in FIGS. 1 and 2.
Le châssis 42 définit au moins une butée de blocage 50, de préférence deux butées (visibles sur la figure 8) du support propre à coopérer avec le support 44 pour le bloquer dans la première et/ou dans la deuxième position.  The chassis 42 defines at least one locking stop 50, preferably two stops (visible in FIG. 8) of the support adapted to cooperate with the support 44 to block it in the first and / or in the second position.
La tour centrale 40 comporte également deux piliers verticaux 52 disposés sur une base 53 (par exemple sous forme d’un chariot), les deux piliers verticaux 52 étant mobiles transversalement par rapport à la base 53. Les piliers verticaux 52 délimitent entre eux une glissière 54 propre à guider la translation verticale du châssis 42 et du support 44 pour placer verticalement le support 44 à la hauteur appropriée pour chaque bobine 24, 30. Avantageusement, la tour 40 est montée mobile sur un rail central 55 dans la direction transversale, comme montré sur les figures 1 et 2. Cette configuration permet notamment au châssis 42 de se déplacer dans la direction transversale entre les première et deuxième bobines 24, 30 pour s’adapter aux différentes largeurs de bobines 24, 30 et de s’engager sur les faces 28, 34 des bobines 24, 30. The central tower 40 also comprises two vertical pillars 52 arranged on a base 53 (for example in the form of a carriage), the two vertical pillars 52 being movable transversely relative to the base 53. The vertical pillars 52 delimit between them a slide 54 to guide the vertical translation of the frame 42 and the support 44 to vertically place the support 44 at the appropriate height for each coil 24, 30. Advantageously, the tower 40 is movably mounted on a central rail 55 in the transverse direction, as shown in FIGS. 1 and 2. This configuration makes it possible for the chassis 42 to move in the transverse direction between the first and second coils 24, 30 to adapt to the different widths of coils 24, 30 and to engage on the faces 28, 34 of the coils 24, 30.
Lorsque le support 44 occupe sa première position, il s’étend en regard de la première tour de guidage 14. Lorsque le support 44 occupe sa deuxième position, il s’étend en regard de la deuxième tour de guidage 18.  When the support 44 occupies its first position, it extends opposite the first guide tower 14. When the support 44 occupies its second position, it extends opposite the second guide tower 18.
Le support 44 comporte une roue d’entrainement 56 de bobine, au moins un moteur de rotation 58, une première butée complémentaire 60, et une deuxième butée complémentaire 62. De préférence, les première et deuxième butées complémentaires 60, 62 comprennent chacune deux régions de butées.  The support 44 comprises a coil drive wheel 56, at least one rotation motor 58, a first complementary abutment 60, and a second complementary abutment 62. Preferably, the first and second complementary abutments 60, 62 each comprise two regions. of stops.
Dans la configuration montrée sur les figures 3 à 7, l’axe de pivotement B-B’ s’étend horizontalement, sensiblement suivant la direction longitudinale. En variante (non- représentée), l’axe de pivotement B-B’ s’étend sensiblement verticalement.  In the configuration shown in Figures 3 to 7, the pivot axis B-B 'extends horizontally substantially in the longitudinal direction. Alternatively (not shown), the pivot axis B-B 'extends substantially vertically.
Lorsque le support 44 occupe sa première position, la roue d’entrainement 56 est disposée en regard de la première bobine 24 pour s’engager sélectivement sur la face opposée 28 de la première bobine 24. Lorsque le support 44 occupe sa deuxième position, la roue d’entrainement 56 est disposée en regard de la deuxième bobine 30 pour s’engager sélectivement sur la face opposée 34 de la deuxième bobine 30.  When the support 44 occupies its first position, the drive wheel 56 is disposed opposite the first coil 24 to engage selectively on the opposite face 28 of the first coil 24. When the support 44 occupies its second position, the drive wheel 56 is disposed facing the second coil 30 to engage selectively on the opposite face 34 of the second coil 30.
Le moteur de rotation 58 est propre à entraîner en rotation la roue d’entrainement 56 et conjointement la bobine 24, 30 qui coopère avec la roue d’entrainement 56, autour de l’axe de rotation A-A’. Avantageusement, le support 44 comporte quatre moteurs de rotation 58 disposés à la périphérie de la roue d’entrainement 56, comme illustré sur la figure 8. Chaque moteur de rotation 58 est avantageusement muni d’une denture externe qui coopère avec la denture externe (non-représentée sur les figures) de la roue d’entrainement 56.  The rotation motor 58 is able to rotate the drive wheel 56 and the coil 24, which cooperates with the drive wheel 56, about the axis of rotation A-A '. Advantageously, the support 44 comprises four rotation motors 58 disposed at the periphery of the drive wheel 56, as illustrated in FIG. 8. Each rotation motor 58 is advantageously provided with an external toothing which cooperates with the external toothing ( not shown in the figures) of the drive wheel 56.
Selon une variante non-représentée sur les figures, le(s) moteur(s) de rotation 58 est (sont) disposé(s) au centre de la roue d’entrainement 56. Les dentures externes de moteur(s) de rotation 58 coopèrent avec la denture interne de la roue d’entrainement 56.  According to a variant not shown in the figures, the motor (s) 58 rotation (s) is (are) arranged (s) in the center of the drive wheel 56. External gear teeth (s) rotation 58 cooperate with the internal toothing of the drive wheel 56.
En référence à la figure 8, la première butée complémentaire 60 est propre à coopérer avec la butée 50 dans la première position du support 44. Elle délimite une première surface de blocage 64 destinée à entrer en appui avec la butée 50 lorsque le support 44 occupe sa première position de sorte à empêcher le support 44 de pivoter au- delà de la première position. De manière similaire, la deuxième butée complémentaire 62 est propre à coopérer avec la butée 50 dans la deuxième position du support 44. Elle délimite une deuxième surface de blocage 66 destinée à entrer en appui avec la butée 50 lorsque le support 44 occupe sa deuxième position de sorte à empêcher le support 44 de pivoter au-delà de la deuxième position. Referring to Figure 8, the first complementary stop 60 is adapted to cooperate with the stop 50 in the first position of the support 44. It defines a first locking surface 64 intended to abut with the stop 50 when the support 44 occupies its first position so as to prevent the support 44 from pivoting beyond the first position. Similarly, the second complementary stop 62 is adapted to cooperate with the stop 50 in the second position of the support 44. It delimits a second locking surface 66 intended to bear against the stop 50 when the support 44 occupies its second position so as to prevent the support 44 from pivoting beyond the second position.
Avantageusement, la butée 50 est amovible ou effaçable pour permettre au support 44 de pivoter librement autour de l’axe B-B’, sur un tour complet. Ainsi, on peut faire pivoter le support 44 de manière à ce que la roue d’entrainement 56 soit dirigée vers le pont 9 du navire de pose 6 et donc, que les moteurs de rotation 58 soient dirigés vers le haut. Les opérations de maintenance sur les moteurs 58 s’en trouvent ainsi facilitées.  Advantageously, the stop 50 is removable or erasable to allow the support 44 to pivot freely about the axis B-B ', on a complete turn. Thus, the support 44 can be pivoted so that the drive wheel 56 is directed towards the deck 9 of the laying ship 6 and thus, that the rotation motors 58 are directed upwards. The maintenance operations on the engines 58 are thus facilitated.
Selon un mode de réalisation de l’invention tel que représenté sur la figure 8, le support 44 comprend en outre un boîtier de connexion 68. Au moins une ligne d’alimentation électrique et/ou hydraulique (non-représentée sur les figures) est disposée à l’intérieur du boîtier de connexion 68 et est propre à fournir au support 44 de l’énergie électrique et/ou du fluide hydraulique pour l’alimentation de moteur(s) de rotation 58.  According to one embodiment of the invention as shown in FIG. 8, the support 44 further comprises a connection box 68. At least one electrical and / or hydraulic power supply line (not shown in the figures) is disposed inside the connection box 68 and is adapted to provide the support 44 with electrical energy and / or hydraulic fluid for the motor (s) 58 (rotation).
Selon un autre mode de réalisation non-représenté, le support 44 est dépourvu de boîtier de connexion 68. Le support 44 comporte au moins un raccord ou joint tournant disposé(s) à l’intérieur de l’axe (ou des axes) de pivotement B-B’ du support 44 par rapport au châssis 42.  According to another embodiment not shown, the support 44 is devoid of connection box 68. The support 44 comprises at least one coupling or rotating joint disposed within the axis (or axes) of pivoting B-B 'of the support 44 relative to the frame 42.
Au moins une ligne d’alimentation électrique et/ou hydraulique alimente les moteurs de rotation 58 par le biais du ou des raccord(s) ou du ou des joint(s) tournant(s).  At least one power supply line and / or hydraulic feeds the rotation motors 58 through the connection (s) or joint (s) turning (s).
Le mécanisme actif de pivotement 46 est propre à faire pivoter le support 44 par rapport au châssis 42 autour de l’axe de pivotement B-B’. Il comporte une crémaillère 72 solidaire de l’un du support 44 et du châssis 42, et un pignon d’entrainement 74 solidaire de l’autre du support 44 et du châssis 42, le pignon d’entrainement 74 coopérant avec la crémaillère 72. Le mécanisme actif de pivotement 46 comporte également un moteur de pivotement 76.  The active pivoting mechanism 46 is adapted to rotate the support 44 relative to the frame 42 about the pivot axis B-B '. It comprises a rack 72 secured to one of the support 44 and the frame 42, and a drive pinion 74 integral with the other of the support 44 and the frame 42, the drive pinion 74 cooperating with the rack 72. The active swivel mechanism 46 also includes a swivel motor 76.
Dans la configuration représentée sur la figure 8, la crémaillère 72 est solidaire du support 44, et le pignon d’entrainement 74 est solidaire du châssis 42. En variante (non- représentée), la crémaillère 72 est solidaire du châssis 42, et le pignon d’entrainement 74 est solidaire du support 44.  In the configuration shown in Figure 8, the rack 72 is secured to the support 44, and the drive pinion 74 is integral with the frame 42. Alternatively (not shown), the rack 72 is integral with the frame 42, and the driving pinion 74 is integral with the support 44.
Le moteur de pivotement 76 est propre à déplacer conjointement la crémaillère 72 et le support 44 par rapport au pignon 74. Il est avantageusement disposé sur le châssis 42.  The pivot motor 76 is able to jointly move the rack 72 and the support 44 relative to the pinion 74. It is advantageously arranged on the frame 42.
Le mécanisme de déplacement 48 de la tour 40 est propre à déplacer transversalement la tour 40 dans sa première position vers une position d’engagement de la roue d’entrainement 56 avec la première bobine 24, et à déplacer la tour 40 dans sa deuxième position vers une position d’engagement de la roue d’entrainement 56 avec la deuxième bobine 30. The movement mechanism 48 of the tower 40 is able to move the tower 40 in its first position transversely to a position of engagement of the drive wheel 56 with the first coil 24, and to move the tower 40 in its second position to an engagement position of the drive wheel 56 with the second coil 30.
Dans cet exemple, le mécanisme de déplacement 48 comporte un ensemble de déplacement transversal 78 constitué par exemple par des vérins (non-représenté sur les figures) propres à entraîner le déplacement transversal de la tour centrale 40. L’ensemble de déplacement transversal 78 permet notamment au support 44 d’avancer et/ou de reculer transversalement par rapport à la première bobine 24 et par rapport à la deuxième bobine 30.  In this example, the displacement mechanism 48 comprises a transverse displacement assembly 78 constituted for example by cylinders (not shown in the figures) adapted to cause the transverse displacement of the central tower 40. The transverse displacement assembly 78 allows in particular the support 44 to advance and / or back transversely relative to the first coil 24 and with respect to the second coil 30.
Avantageusement, le mécanisme de déplacement 48 comporte également un ensemble de déplacement vertical (non-visible sur les figures), constitué par exemple par au moins un vérin, propre à entraîner la montée et/ou la descente du châssis 42 dans la glissière 54 suivant la direction verticale afin d’adapter la hauteur du support 44 et donc la hauteur de la roue d’entrainement 56 par rapport à la face opposée 28 de la première bobine 24 et/ou la face opposée 34 de la deuxième bobine 30 avant leur engagement, et propre à monter et/ou descendre les première et deuxième bobines 24, 30 avant l’enroulement et/ou déroulement de la ligne flexible 8.  Advantageously, the displacement mechanism 48 also comprises a set of vertical displacement (not visible in the figures), constituted for example by at least one jack, suitable for driving up and / or down the frame 42 in the slide 54 following the vertical direction to adapt the height of the support 44 and thus the height of the drive wheel 56 relative to the opposite face 28 of the first coil 24 and / or the opposite face 34 of the second coil 30 before their engagement , and suitable for mounting and / or lowering the first and second coils 24, 30 before the winding and / or unwinding of the flexible line 8.
Avantageusement, le mécanisme de déplacement 48 comporte également un ensemble de déplacement longitudinal (non-visible sur les figures) disposé au niveau de la base 51. L’ensemble de déplacement longitudinal est constitué par exemple par au moins un vérin (non-visible sur les figures). L’ensemble de déplacement longitudinal est propre à déplacer la tour 40 le long du rail central 55 pour permettre à la roue d’entrainement 56 de s’engager avec d’autres bobines de stockage disposées sur le premier rang et/ou le deuxième rang.  Advantageously, the displacement mechanism 48 also comprises a longitudinal displacement assembly (not visible in the figures) disposed at the level of the base 51. The longitudinal displacement assembly is constituted for example by at least one jack (not visible on the figures). The longitudinal displacement assembly is adapted to move the tower 40 along the central rail 55 to allow the drive wheel 56 to engage with other storage coils disposed on the first row and / or the second row. .
Le fonctionnement du dispositif d’entrainement 22 pour enrouler et/ou dérouler des tronçons de lignes flexibles 8 va maintenant être décrit.  The operation of the drive device 22 for winding and / or unrolling sections of flexible lines 8 will now be described.
L’enroulement d’un tronçon de ligne flexible 8 est par exemple effectué lors du chargement du navire de pose 6.  The winding of a section of flexible line 8 is for example carried out during the loading of the laying ship 6.
Le déroulement d’un tronçon de ligne flexible 8 est exécuté lors de la pose du tronçon, typiquement dans l’étendue d’eau.  The course of a flexible line section 8 is performed during the laying of the section, typically in the body of water.
Initialement, la première tour 14 coopère avec la face 26 de la première bobine 24, et la deuxième tour 18 coopère avec la face 32 de la deuxième bobine 30. Le support 44 occupe sa première position en regard de la première bobine 24, comme illustré sur la figure 3. La butée de blocage 50 coopère avec la première butée complémentaire 60, la butée de blocage 50 étant placée en appui sur la première surface de blocage 64 de sorte à empêcher le support 44 de pivoter davantage à l’écart de la première position. Lorsqu’un utilisateur souhaite enrouler et/ou dérouler la ligne flexible 8 enroulée sur la première bobine 14, l’ensemble de déplacement transversal 78 déplace transversalement la tour centrale 40 vers la première bobine 24. L’ensemble de déplacement vertical déplace verticalement le châssis 42, en le guidant en translation dans la glissière 54 pour adapter la hauteur de la roue d’entrainement 56 par rapport à la première bobine 24. Les déplacements suivant les directions transversale et verticale permettent à la roue d’entrainement 56 de s’engager avec la face opposée 28 de la première bobine 24. Initially, the first tower 14 cooperates with the face 26 of the first coil 24, and the second tower 18 cooperates with the face 32 of the second coil 30. The support 44 occupies its first position opposite the first coil 24, as illustrated in FIG. 3. The locking abutment 50 cooperates with the first complementary abutment 60, the locking abutment 50 being placed in abutment on the first locking surface 64 so as to prevent the support 44 from pivoting further away from the first position. When a user wishes to wind and / or unwind the flexible line 8 wound on the first coil 14, the transverse displacement assembly 78 transversely displaces the central tower 40 towards the first coil 24. The vertical displacement assembly moves the chassis vertically 42, by guiding it in translation in the slide 54 to adjust the height of the drive wheel 56 relative to the first coil 24. The displacements in the transverse and vertical directions allow the drive wheel 56 to engage with the opposite face 28 of the first coil 24.
Ensuite, les ensembles de déplacement vertical de la tour centrale 40 et de la première tour 14 sont activés conjointement pour élever la première bobine 24 hors de son berceau.  Then, the vertical displacement assemblies of the central tower 40 and the first tower 14 are activated together to raise the first coil 24 out of its cradle.
Puis, les moteurs de rotation 58 entraînent en rotation la roue d’entrainement 56 autour de l’axe de rotation A-A’, ce qui provoque la rotation de la roue d’entrainement 56 conjointement avec la rotation de la première bobine 24. La ligne flexible 8 s’enroule sur la première bobine 24 ou se déroule à l’écart de celle-ci.  Then, the rotation motors 58 rotate the drive wheel 56 about the axis of rotation A-A ', which causes rotation of the drive wheel 56 together with the rotation of the first coil 24. The flexible line 8 wraps on the first coil 24 or runs away from it.
Avantageusement, la première roue 29 est également entraînée en rotation de manière simultanée avec la roue d’entrainement 56.  Advantageously, the first wheel 29 is also rotated simultaneously with the drive wheel 56.
Lorsque l’enroulement ou le déroulement se termine, les moteurs de rotation 58 sont arrêtés. Les ensembles de déplacement vertical de la tour centrale 40 et de la première tour 14 sont alors activés conjointement pour abaisser la première bobine 24 dans son berceau.  When the winding or unwinding ends, the rotation motors 58 are stopped. The sets of vertical displacement of the central tower 40 and the first tower 14 are then activated jointly to lower the first coil 24 in its cradle.
Pour enrouler et/ou dérouler la ligne flexible 8 sur la deuxième bobine 30, l’ensemble de déplacement transversal 78 déplace ensuite la tour centrale 40 à l’écart de la première bobine 24 suivant la direction transversale jusqu’à une position sensiblement équidistante entre les première et deuxième bobines 24, 30. La roue d’entrainement 56 est alors dégagée de la première bobine 24.  To wind and / or unroll the flexible line 8 on the second coil 30, the transverse displacement assembly 78 then moves the central tower 40 away from the first coil 24 in the transverse direction to a substantially equidistant position between the first and second coils 24, 30. The drive wheel 56 is then disengaged from the first coil 24.
Puis, le moteur de pivotement 76 entraîne en rotation le pignon 74 par rapport à la crémaillère 72.  Then, the pivot motor 76 rotates the pinion 74 relative to the rack 72.
La rotation du pignon 74 entraîne le pivotement du support 44 autour de l’axe de pivotement B-B’, et le support 44 passe progressivement de sa première position à sa deuxième position. Le pivotement du support 44 entraîne le pivotement conjoint de la roue d’entrainement 56, comme illustré par les figures 4 à 6.  The rotation of the pinion 74 causes the support 44 to pivot about the pivot axis B-B ', and the support 44 progressively moves from its first position to its second position. The pivoting of the support 44 causes the joint wheel 56 to pivot together, as illustrated by FIGS. 4 to 6.
Le pivotement du support 44 se poursuivant, la butée de blocage 50 bute contre la deuxième surface de blocage 66 de la deuxième butée complémentaire 62. Ceci empêche le support 44 de pivoter au-delà de sa deuxième position. L’ensemble de déplacement vertical déplace le châssis 42 suivant la direction verticale, le châssis 42 étant guidé en translation par la glissière 54. Ainsi, la hauteur de la roue d’entraînement 56 est adaptée pour coopérer avec la face opposée 34 de la deuxième bobine 30. The pivoting of the support 44 continues, the stopper 50 abuts against the second locking surface 66 of the second complementary stopper 62. This prevents the support 44 from pivoting beyond its second position. The vertical displacement assembly moves the frame 42 in the vertical direction, the frame 42 being guided in translation by the slideway 54. Thus, the height of the drive wheel 56 is adapted to cooperate with the opposite face 34 of the second coil 30.
Puis, l’ensemble de déplacement transversal 78 déplace la tour centrale 40 vers la deuxième bobine 30 suivant la direction transversale, entraînant ainsi le déplacement de la roue d’entrainement 56 jusqu’à ce que celle-ci coopère avec la face opposée 34 de la deuxième bobine, comme représenté sur la figure 7.  Then, the transverse displacement assembly 78 moves the central tower 40 towards the second coil 30 in the transverse direction, thereby causing the driving wheel 56 to move until it co-operates with the opposite face 34 of the second coil, as shown in Figure 7.
A nouveau, les ensembles de déplacement vertical de la tour centrale 40 et de la deuxième tour 18 sont activés conjointement pour élever la deuxième bobine 30 hors de son berceau.  Again, the vertical displacement assemblies of the central tower 40 and the second tower 18 are activated together to raise the second coil 30 out of its cradle.
Le moteur de rotation 58 entraîne en rotation la roue d’entrainement 56 autour de l’axe de rotation A-A’. La rotation de la roue d’entrainement 56 provoque la rotation conjointe de la deuxième bobine 30, de sorte que la ligne flexible 8 enroulée sur celle-ci s’enroule sur la deuxième bobine 30 et/ou se déroule de la deuxième bobine 30.  The rotation motor 58 rotates the drive wheel 56 about the axis of rotation A-A '. The rotation of the drive wheel 56 causes the second coil 30 to rotate jointly, so that the flexible line 8 wound on it coils on the second coil 30 and / or unwinds from the second coil 30.
Avantageusement, la deuxième roue 35 est également entraînée en rotation de manière simultanée avec la roue d’entrainement 56.  Advantageously, the second wheel 35 is also rotated simultaneously with the drive wheel 56.
Lorsque l’enroulement et/ou le déroulement de la ligne flexible 8 sur la deuxième bobine 30 se termine, le moteur de rotation 58 est arrêté.  When winding and / or unwinding of the flexible line 8 on the second coil 30 ends, the rotation motor 58 is stopped.
Les ensembles de déplacement vertical de la tour centrale 40 et de la deuxième tour 18 sont alors activés conjointement pour abaisser la deuxième bobine 30 dans son berceau.  The vertical displacement assemblies of the central tower 40 and the second tower 18 are then activated jointly to lower the second coil 30 in its cradle.
L’ensemble de déplacement transversal 78 déplace la tour centrale 40 à l’écart de la deuxième bobine 30 suivant la direction transversale, et la roue d’entrainement 56 se dégage de la deuxième bobine 30.  The transverse displacement assembly 78 moves the central tower 40 away from the second coil 30 in the transverse direction, and the drive wheel 56 disengages from the second coil 30.
Lorsque l’ensemble d’enroulement et/ou de déroulement 10 comporte plusieurs bobines disposées les unes à la suite des autres le long de la direction longitudinale, une autre bobine peut alors être entraînée en rotation pour enrouler et/ou dérouler un autre tronçon de ligne flexible 8.  When the winding and / or unwinding assembly 10 comprises a plurality of coils arranged one after the other along the longitudinal direction, another coil can then be rotated to wind and / or unroll another section of flexible line 8.
L’ensemble de déplacement longitudinal déplace la tour centrale 40 et la première tour 14 et/ou la deuxième tour 18 suivant la direction longitudinale de sorte que la première tour 14 et/ou la deuxième tour 18 et la tour centrale 40 soient positionnées en regard de la bobine suivante pour enrouler et/ou dérouler les lignes flexibles 8 comme décrit précédemment. L’ensemble de déplacement transversal 78 et/ou l’ensemble de déplacement vertical peuvent également être utilisé(s) pour ajuster la hauteur et/ou la position transversale du support 44. Grâce à l’invention décrite ci-dessus, il n’est plus nécessaire de prévoir de mécanisme de transmission de couple entre deux roues d’entrainement dans le dispositif d’entrainement. En effet, une seule roue d’entrainement est nécessaire pour enrouler et/ou dérouler les lignes flexibles 8 enroulées sur les bobines disposées sur deux rangs. The longitudinal displacement assembly moves the central tower 40 and the first tower 14 and / or the second tower 18 in the longitudinal direction so that the first tower 14 and / or the second tower 18 and the central tower 40 are positioned facing each other. the next coil for winding and / or unwinding the flexible lines 8 as previously described. The transverse displacement assembly 78 and / or the vertical displacement assembly may also be used to adjust the height and / or the transverse position of the support 44. Thanks to the invention described above, it is no longer necessary to provide a torque transmission mechanism between two drive wheels in the drive device. Indeed, a single drive wheel is required to wind and / or unwind the flexible lines 8 wound on the coils arranged in two rows.
De plus, l’élimination de la deuxième roue d’entrainement simplifie la conception et la fabrication du dispositif d’entrainement 22. L'accès aux moteurs est également rendu plus simple.  In addition, the elimination of the second drive wheel simplifies the design and manufacture of the drive device 22. Access to the motors is also made simpler.
