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-F119, «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.Are 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-F119, "Recommended Practice - Thermoplastic composite pipes", published December 2015 by the DNV GL (Det Norske Veritas GL), pipes made from a composite material comprising a thermosetting matrix reinforced with fibers, or even so-called hybrid flexible pipes which have an intermediate structure between that of TCP flexible pipes and those flexible pipes of the unbonded 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).Also, the device according to the invention can be used for winding and/or unwinding rigid pipes as described for example in the normative document DNV_OS-F101 (Submarine Pipeline Systems) October 2013 Edition , compiled by 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 .The storage reel usually comprises a cylindrical barrel flanked by two flanges making it possible to laterally retain the flexible pipe wound around the barrel. The flanges have respectively a rim and inside a concentric hub, the two being connected together by spokes. The flanges form the side faces of the storage coil. Examples of storage coils are described in the 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 arrange two rows of coils in parallel with respect to 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 placed between a first side rail and a central rail, and a second row of coils is placed 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 coils are typically arranged on supports also called cradles, welded to the deck of the laying boat in order to hold the coils in place during their 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.To wind and/or unwind the flexible lines on the reels arranged in two parallel rows, a device for driving the reels in rotation 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 driving device comprises a first driving wheel directed towards the first row of coils to engage with the coils of the first row, and a second driving wheel directed towards the second row of coils to engage with the second row coils. 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 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 reel on the first row of reels, the first drive wheel is engaged with the first reel, so that the first reel is driven in rotation. . Then, to wind and/or unwind a flexible line carried by a second reel on the second row of reels, the second drive wheel is engaged with the second reel.

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 reel.

Cependant, ce dispositif ne donne cependant pas entière satisfaction.However, this device does not however 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 torque transfer from the first drive wheel to the second drive wheel is not always reliable. To transfer torque more efficiently and to strengthen 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. Machining includes, for example, the creation of grooves or serrations along the entire length of the transmission shaft. This type of machining increases the manufacturing cost compared to a shaft-hub transmission with pin connections or with key connections.

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 dual drive wheel configuration makes it difficult to access the drive motors during technical maintenance. Indeed, the second drive wheel masks access to the motors, and it is necessary to remove it 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 the selective drive of coils located on a first row and a second row of coils by a common drive device more reliable, 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 what follows, the terms "longitudinal" and "transverse" are understood in relation to the normal direction of elongation of a laying vessel, 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. Le navire de pose 6 est destiné à convoyer la ligne flexible 8 jusqu'au lieu de pose, aux fins de l'installer dans une étendue d'eau.A first laying vessel 6 of at least one flexible line 8 is partially illustrated on the figures 1 and 2 . The laying vessel 6 is intended to convey the flexible line 8 to the laying location, for the purpose of installing it in a body of water.

L'étendue d'eau est par exemple, une mer, un lac ou un océan. La profondeur de l'étendue d'eau au droit de l'installation d'exploitation de fluide est par exemple comprise entre 20 m et 4000 m.The body of water is, for example, a sea, a lake or an ocean. The depth of the stretch of water in line with the fluid exploitation installation is for example between 20 m and 4000 m.

La ligne flexible 8 est notamment une conduite flexible telle que décrite par exemple dans les documents normatifs API 17J (Spécification for Unbonded Flexible Pipe), API RP 17B (Recommended Practice for Flexible Pipe) et API 16C (Choke and Kill Equipment) établis par l'American Petroleum Institute. La conduite flexible est avantageusement de type non liée (« unbonded » en anglais).The flexible line 8 is in particular a flexible pipe as described for example in the normative documents API 17J (Specification for Unbonded Flexible Pipe), API RP 17B (Recommended Practice for Flexible Pipe) and API 16C (Choke and Kill Equipment) established by the 'American Petroleum Institute. The flexible pipe is advantageously of the unbonded type.

La conduite est généralement formée d'un ensemble de couches concentriques et superposées. Elle est considérée comme « non liée » au sens de la présente invention dès lors qu'au moins une des couches de la conduite est apte à se déplacer longitudinalement par rapport aux couches adjacentes lors d'une flexion de la conduite. En particulier, une conduite non liée est une conduite dépourvue de matériaux liants raccordant des couches formant la conduite.The pipe is generally formed of a set of concentric and superposed layers. It is considered to be “unbonded” within the meaning of the present invention when at least one of the layers of the pipe is able to move longitudinally with respect to the adjacent layers during bending of the pipe. In particular, an unbonded pipe is a pipe devoid of binder materials connecting layers forming the pipe.

En variante, la conduite flexible est un faisceau composite de type « integrated production bundle », comprenant un noyau central formé par une structure de conduite flexible standard du type de celle définie ci-dessus par les documents normatifs et un assemblé comportant au moins un tube, un câble ou un tuyau, enroulé autour du noyau central. La principale fonction de l'assemblé est de fournir un chauffage actif au fluide d'hydrocarbures circulant dans le noyau central. Par exemple, ledit au moins un tube permet le transport d'un fluide régulé thermiquement. Alternativement, ledit au moins un tube permet le drainage de gaz. 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.As a variant, the flexible pipe is a composite bundle of the “integrated production bundle” type, 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 primary function of the assembly is to provide active heating to the hydrocarbon fluid flowing through the central core. For example, said at least one tube allows the transport of a thermally regulated fluid. Alternatively, said at least one tube allows the drainage of gas. The assembly may also include at least one cable for transporting electrical power or information between the bottom and the surface of the body of water. Also, the assembly may include at least one pipe for transporting hydraulic power or even a service fluid to allow easy restarting of production of the flexible pipe after a long shutdown. Finally, the assembly may also include mechanical reinforcement elements (or “fillers”) capable of 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 « Specification for Subsea Umbilicals » .More generally, the flexible line is an umbilical, as described in the normative document published by American Petroleum Institute (API), API17E “Specification for Subsea Umbilicals” .

En variante encore, la ligne flexible est un câble sous-marin de transport d'énergie ou de télécommunications.As a further variant, the flexible line is an undersea energy transport or telecommunications cable.

En outre, la ligne flexible est une conduite flexible réalisée à partir d'un matériau composite comprenant une matrice thermoplastique ou est une conduite flexible hybride.In addition, the flexible line is a flexible pipe made from a composite material comprising a thermoplastic matrix or is a hybrid flexible pipe.

La première bobine 24 comporte une face 26 disposée en regard de la première tour 14 et une face opposée 28. La première tour 14 comporte une première roue 29 propre à coopérer avec la face 26 de la première bobine 24, et un ensemble de déplacement vertical (non-représenté sur les figures) de la première tour 14 propre à déplacer la première roue 29 dans la direction verticale.The first coil 24 comprises a face 26 arranged opposite the first tower 14 and an opposite face 28. The first tower 14 comprises a first wheel 29 capable of cooperating with the face 26 of the first coil 24, and a vertical displacement assembly (Not shown in the figures) of the first tower 14 capable of moving 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 vessel 6. The first tower 14 is movably mounted on the first rail 16 in the horizontal direction, the movement of the first tower 14 being guided by the first rail 16. By “substantially along the longitudinal direction”, it is meant for example that the first rail 16 extends along the longitudinal direction or is inclined with respect to the longitudinal direction by an angle of 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 guide in rotation a second storage reel 30 of flexible line 8. The second reel 30 has a face 32 facing the second tower 18 and an opposite face 34. The second tower 18 comprises a second wheel 35 capable of cooperating with the face 32 of the second coil 30, and a vertical movement assembly (not shown in the figures) of the second tower 18 capable of moving the second wheel 35 in the vertical direction.

The second tower 18 is movably mounted on the second rail 20 in the horizontal direction, the movement 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 drive the coil 24, 30 in rotation about a horizontal axis of rotation. A-A'.

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 drive device 22 also includes an active mechanism 46 for pivoting the support 44 (visible on the figure 8 ) and a moving 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 able to be positioned transversely between the first guide tower 14 and the second guide tower 18, as shown in the figures 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 frame 42 defines at least one locking abutment 50, preferably two abutments (visible on the figure 8 ) of the support suitable for cooperating 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.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 with respect to the base 53. The vertical pillars 52 delimit between them a slide 54 adapted to guide the vertical translation of the frame 42 and the support 44 to place the support 44 vertically at the appropriate height for each reel 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.Advantageously, the tower 40 is movably mounted on a central rail 55 in the transverse direction, as shown in the figures 1 and 2 . This configuration allows in particular the frame 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 reel 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 on the figures 3 to 7 , the pivot axis BB' extends horizontally, substantially in the longitudinal direction. Alternatively (not shown), the pivot pin BB' 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 arranged facing 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 arranged 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 capable of rotating the drive wheel 56 and jointly the coil 24, 30 which cooperates with the drive wheel 56, around the axis of rotation A-A'. Advantageously, the support 44 comprises four rotation motors 58 arranged at the periphery of the drive wheel 56, as illustrated in the figure 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 rotation motor(s) 58 is (are) arranged at the center of the drive wheel 56. The external teeth of the rotation motor(s) 58 cooperate with the internal teeth 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.With reference to the figure 8 , the first complementary stop 60 is capable of cooperating with the stop 50 in the first position of the support 44. prevent support 44 from pivoting past the first 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.Similarly, the second complementary abutment 62 is capable of cooperating with the abutment 50 in the second position of the support 44. It delimits a second blocking surface 66 intended to come into contact with the abutment 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 around the axis B-B', over 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 vessel 6 and therefore the rotation motors 58 are directed upwards. The maintenance operations on the motors 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 the figure 8 , the support 44 further comprises a connection box 68. At least one electrical and/or hydraulic supply line (not shown in the figures) is arranged inside the connection box 68 and is capable of supplying the support 44 of electrical energy and/or hydraulic fluid for powering rotation motor(s) 58.

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 has no connection box 68. The support 44 comprises at least one coupling or rotary joint arranged inside the axis (or axes) of pivoting B-B' of support 44 relative to 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 electric and/or hydraulic supply line supplies the rotation motors 58 via the connection(s) or the rotary joint(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 capable of causing the support 44 to pivot relative to the frame 42 around the pivoting axis B-B'. It comprises a rack 72 secured to one of the support 44 and the frame 42, and a drive pinion 74 secured to 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 the figure 8 , the rack 72 is secured to the support 44, and the drive pinion 74 is secured to the frame 42. Alternatively (not shown), the rack 72 is secured to the frame 42, and the drive pinion 74 is secured to 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 capable of jointly moving 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 transversely in its first position towards a position of engagement of the drive wheel 56 with the first coil 24, and to move the tower 40 into its second position. towards a position of engagement 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 on the figures) capable of driving the transverse displacement of the central tower 40. The transverse displacement assembly 78 notably allows the support 44 to advance and/or retreat transversely with respect 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 vertical displacement assembly (not visible in the figures), constituted for example by at least one jack, capable of causing the raising and/or lowering of the frame 42 in the slideway 54 following the vertical direction in order to adapt the height of the support 44 and therefore the height of the drive wheel 56 with respect 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 raising and/or lowering the first and second reels 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 includes 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 cylinder (not visible on the figures). The longitudinal movement assembly is adapted to move the tower 40 along the central rail 55 to allow the drive wheel 56 to engage with other storage reels arranged 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 unwinding 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 vessel 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 unwinding of a section of flexible line 8 is performed when laying 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.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 facing the first coil 24, as illustrated on the figure 3 . The blocking abutment 50 cooperates with the first complementary abutment 60, the blocking abutment 50 being placed bearing on the first blocking surface 64 so as to prevent the support 44 from pivoting further away from the first 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.When a user wishes to wind and/or unwind the flexible line 8 wound on the first reel 14, the transverse movement assembly 78 moves the central tower 40 transversely towards the first reel 24. The vertical movement assembly moves the frame vertically 42, guiding it in translation in the slide 54 to adapt the height of the drive wheel 56 relative to the first coil 24. Movements 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.Next, the central tower 40 and first tower 14 vertical displacement assemblies are activated together to raise the first spool 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 around the axis of rotation A-A', which causes the rotation of the drive wheel 56 together with the rotation of the first coil 24. The flexible line 8 winds up on the first reel 24 or unwinds 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 driven in rotation 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 vertical displacement assemblies of the central tower 40 and of the first tower 14 are then activated jointly to lower the first coil 24 into 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 unwind the flexible line 8 on the second reel 30, the transverse movement assembly 78 then moves the central tower 40 away from the first reel 24 in the transverse direction to a position substantially equidistant 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 pivoting 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.Rotation of pinion 74 causes support 44 to pivot about pivot axis B-B', and support 44 moves progressively from its first position to its second position. The pivoting of the support 44 causes the joint pivoting of the drive wheel 56, as illustrated by the figures 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.The pivoting of the support 44 continuing, the blocking abutment 50 abuts against the second blocking surface 66 of the second complementary abutment 62. This prevents the support 44 from pivoting beyond its second 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 vertical movement assembly moves the frame 42 in the vertical direction, the frame 42 being guided in translation by the slide 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 movement assembly 78 moves the central tower 40 towards the second coil 30 in the transverse direction, thus causing the movement of the drive wheel 56 until the latter cooperates with the opposite face 34 of the second coil, as shown in the 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 central tower 40 and second tower 18 vertical displacement assemblies are activated together to raise the second spool 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 around the axis of rotation A-A'. The rotation of the drive wheel 56 causes the joint rotation of the second reel 30, so that the flexible line 8 wound on the latter winds up on the second reel 30 and/or unwinds from the second reel 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 driven in rotation 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 the winding and/or unwinding of the flexible line 8 on the second reel 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 of the second tower 18 are then activated jointly to lower the second reel 30 into 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.Transverse travel assembly 78 moves center tower 40 away from second spool 30 in the transverse direction, and drive wheel 56 disengages from second spool 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 entrainée en rotation pour enrouler et/ou dérouler un autre tronçon de ligne flexible 8.When the winding and/or unwinding assembly 10 comprises several reels arranged one after the other along the longitudinal direction, another reel can then be driven in rotation to wind and/or unwind 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.The longitudinal movement 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 opposite of the following reel to wind and/or unwind the flexible lines 8 as previously described. The transverse displacement assembly 78 and/or the vertical displacement assembly can also be used to adjust the height and/or the transverse position of the 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.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 necessary to wind and/or unwind the flexible lines 8 wound on the reels 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.
