Description

La présente invention concerne un dispositif d'enroulement de conduites tubulaires flexibles.The present invention relates to a device for winding flexible tubular conduits.

Les conduites dont il s'agit sont notamment les conduites de transport d'hydrocarbures posées sous l'eau à partir de navires de pose. De telles conduites sont bien connues et peuvent être continues ou faites de tronçons assemblés. Leur rigidité est variable et l'on entend ici par conduites flexibles simplement indiquer qu'elles sont enroulables sans déformation plastique en bobines de grand diamètre.The conducts in question are in particular the hydrocarbon transport pipes laid under water from laying ships. Such conduct are well known and can be continuous or made of assembled sections. Their rigidity is variable and here we mean by flexible pipes simply indicate that they can be rolled up without deformation plastic in large diameter coils.

Les conduites tubulaires flexibles sont fabriquées en grande longueur à terre et doivent être ensuite transportées sur le lieu de pose, soit directement sur le navire de pose quand la distance entre le chantier à terre et le lieu de pose n'est pas trop grande, soit généralement sur une barge de transport intermédiaire qui les conduira au navire de pose.Flexible tubular lines are manufactured in great length on the ground and must be then transported to the installation site, either directly on the laying vessel when the distance between the site on land and the place of installation is not too large, usually on a transport barge intermediary who will take them to the laying ship.

On connaít principalement deux types de conteneurs à quai et à bord pour l'enroulement des conduites, à savoir les bobines et les carrousels. Une bobine est constituée par un axe d'enroulement horizontal maintenu entre deux joues, le tout d'une taille moyenne (par exemple 9x9x5 m3) et d'une capacité en rapport (190 tonnes), tandis qu'un carrousel est défini par un vaste plateau à colonne d'enroulement centrale d'axe vertical, le tout d'une très grande taille (par exemple de 16m de rayon) et capacité (2000 tonnes). Tandis que les bobines peuvent être manipulées individuellement assez facilement, les carrousels ne le peuvent pas. Le chargement d'une conduite depuis le quai jusqu'à bord se fait selon trois solutions : soit par transport de bobines (solution appelée ci-après bobine-bobine), soit par transfert de la conduite depuis des bobines à quai sur un carrousel à bord (ci-après solution bobine-carrousel), soit par transfert de la conduite depuis un carrousel à quai sur un carrousel à bord (ci-après solution carrousel-carrousel).There are mainly two types of container dockside and on board for winding pipes, namely coils and carousels. A reel is made up of a horizontal winding axis held between two cheeks, all of a medium size (for example 9x9x5 m 3 ) and a related capacity (190 tonnes), while a carousel is defined by a large central winding column tray with a vertical axis, all of a very large size (for example with a radius of 16m) and capacity (2000 tonnes). While the reels can be handled individually fairly easily, the carousels cannot. The loading of a pipe from the quay to the ship is done according to three solutions: either by transport of reels (solution called hereinafter reel-reel), or by transfer of the pipe from reels to quay on a carousel to on board (hereinafter reel-carousel solution), or by transfer of the pipe from a dock carousel to an on-board carousel (hereinafter carousel-carousel solution).

Les inconvénients des bobines sont d'une part que leur petit diamètre exige des conduites qu'elles soient assez flexibles (qu'elles admettent un relativement petit rayon minimal de flexion), et que leur longueur enroulée ne soit pas très grande. Si la conduite est en bobines à bord (solution bobine-bobine), la longueur totale embarquée est moyenne, et le coût de retour à vide des bobines est élevé, compte tenu de la place perdue. En revanche, la solution bobine-bobine est particulièrement flexible lors du chargement à quai, et le chargement s'opère de manière rapide et sûre.The disadvantages of coils are on the one hand that their small diameter requires pipes they are flexible enough (that they admit a relatively small minimum bending radius), and that their coiled length is not very large. If driving is in coils on board (coil-coil solution), the total length on board is average, and the cost of empty return of the coils is high, given the lost place. On the other hand, the coil-coil solution is particularly flexible when loading at dock, and loading takes place quickly and safe.

Dans la solution bobine-carrousel, la longueur totale embarquée est plus grande, mais le transfert de bobines à carrousel est long (ce qui entraíne des coûts d'immobilisation du bateau) et induit des risques de torsion de la conduite. De plus, le retour à vide du carrousel du bateau est cher.In the coil-carousel solution, the length total onboard is greater, but the transfer of carousel reels is long (which results in vessel immobilization costs) and induces risk of twisting the pipe. In addition, the return to empty carousel is expensive.

La solution carrousel-carrousel permet d'embarquer des conduites à la fois considérablement plus longues et éventuellement moins flexibles, mais non seulement l'opération de chargement est, comme dans le cas précédent, lente et peu flexible, mais des risques de blocage total de la production ne sont pas exclus en cas de problèmes lors de l'enroulement. Le problème du retour à vide n'est pas non plus résolu.The carousel-carousel solution allows to board pipes at a time considerably longer and possibly less flexible, but not only the loading operation is, as in the previous case, slow and inflexible, but risks of total blockage of production are not excluded in case of problems during winding. The the problem of the empty return is not resolved either.

On connaít dans le cadre de l'enroulement et du transport de câbles ou éléments analogues, des bobines à deux flasques reliées par un moyeu de dimensions moyennes, partiellement repliables. Par exemple, le brevet FR 2 698 623 A montre une bobine à deux flasques dont la particularité est que les flasques peuvent être rabattues le long d'une corde. Selon les documents US 5 649 677 A, US 5 547 147 A, EP 0 745 549 A ou DE 35 36555 A, au contraire c'est le moyeu qui est repliable. Ces solutions, qui n'apportent au maximum qu'un gain de place assez faible dans le sens radial des flasques, ne sont pas transposables au domaine des bobines et carrousels de grandes dimensions concernées par l'invention.We know in the context of winding and transporting cables or the like, coils with two flanges connected by a hub medium dimensions, partially foldable. Through example, patent FR 2 698 623 A shows a coil with two flanges whose particularity is that the flanges can be folded down along a rope. According to documents US 5,649,677 A, US 5,547,147 A, EP 0 745 549 A or DE 35 36 555 A, on the contrary it is the hub which is foldable. These solutions, which only provide to the maximum that a fairly small space saving in the radial direction of the flanges, cannot be transposed to large coils and carousels concerned with the invention.

On connaít par US 5 409 179 une bobine d'enroulement à bras mobiles, conforme au préambule de la revendication annexée 1. La mobilité des bras est destinée à une extraction facile du fil enroulé.We know from US 5 409 179 a coil winding arm, in accordance with the preamble of the appended claim 1. The mobility of the arms is intended for easy extraction of the coiled wire.

On connaít par US-3 072 358 aussi un dispositif d'enroulement comportant plusieurs roues à deux bras croisés, les bras étant immobiles.Known from US-3,072,358 also a winding device comprising several wheels with two crossed arms, the arms being stationary.

Le but de l'invention est de développer une nouvelle possibilité de transport des conduites grâce à un dispositif d'enroulement mieux adapté, qui évite la plupart des inconvénients des solutions connues sans en perdre les avantages.The object of the invention is to develop a new possibility of transporting pipes thanks to a better adapted winding device, which avoids the most of the disadvantages of known solutions without lose the benefits.

Selon l'invention, on propose un dispositif d'enroulement de conduite tubulaire flexible, conforme à la revendication 1. Ceci permet d'une part de diminuer considérablement le volume de la roue à vide et d'autre part d'empiler plusieurs roues sur une palette d'empilage spécifique disposée sur le pont du bateau, laquelle peut comporter ou non une colonne de centrage des roues d'enroulement. La palette est de préférence motorisée pour permettre le déroulement du flexible dans les mêmes conditions qu'avec un carrousel classique.According to the invention, a device is proposed flexible tubular pipe winding to claim 1. This allows on the one hand to considerably reduce the volume of the idle wheel and on the other hand to stack several wheels on one specific stacking pallet placed on the deck of the boat, which may or may not include a column of centering of the winding wheels. The palette is preferably motorized to allow the progress of the flexible under the same conditions as with a carousel classic.

Il est avantageux que le moyeu des roues soit auto-empilable. Il est aussi avantageux que le moyeu des roues soit d'une taille permettant, près repliement des bras, de transporter la roue dans un conteneur de taille standard. Il est également avantageux de prévoir au moins une butée d'enroulement intérieure, de préférence radialement réglable, et/ou extérieure est prévue sur les rayons.It is advantageous if the wheel hub is self-stackable. It is as advantageous as the hub wheels be of a size allowing, close folding arms, to transport the wheel in a container of standard size. It is also advantageous to plan at least one internal winding stopper, preferably radially adjustable, and / or external is provided on the shelves.

Avantageusement, chaque rayon comporte sur sa longueur une ou plusieurs articulations permettant de le rabattre sur lui-même, ce qui réduit encore le volume de la roue à vide.Advantageously, each department has on its length one or more joints allowing fold it back on itself, which further reduces the empty wheel volume.

Avantageusement, chaque rayon comporte deux parties articulées ramifiées susceptibles de donner quand elles sont déployées dans ledit plan radial une très grande capacité différente d'enroulement.Advantageously, each department has two branched articulated parts liable to give when they are deployed in said radial plane a very large different winding capacity.

Grâce à ces caractéristiques, il est possible de manipuler à l'aide de grues à quai ou à bord individuellement les roues d'enroulement avec la rapidité, la modularité et la flexibilité de la manipulation des bobines classiques, mais sans être pour autant limité en matière de flexibilité parce que les roues peuvent avoir un diamètre de l'ordre de celui d'un carrousel classique et non d'une bobine. Les roues avec leur enroulement sont empilées à bord sur la palette associée et forment un carrousel aux avantages comparables à ceux d'un carrousel classique.Thanks to these features, it is possible to handle using cranes at the dock or on board individually the winding wheels with speed, the modularity and flexibility in handling classic coils, but without being limited in terms of flexibility because the wheels can have a diameter of the order of that of a carousel classic and not a coil. The wheels with their winding are stacked on board on the pallet associated and form a carousel with advantages comparable to those of a classic carousel.

D'autres caractéristiques et avantages de l'invention apparaítront à la lecture de la description suivante de plusieurs exemples de réalisation, se référant aux dessins annexés sur lesquels :

Other characteristics and advantages of the invention will appear on reading the following description of several exemplary embodiments, referring to the appended drawings in which:
  • FIG. 1 is a schematic perspective view of a wheel according to the invention,
  • FIG. 2 is a schematic side view of a specific pallet for stacking wheels according to the invention,

La figure 1 montre une roue ou araignée 1 constituée d'un moyeu cylindrique 2, autour duquel s'étend dans un plan radial une pluralité de bras radiaux ou rayons 3. Les rayons sont reliés au moyeu 2 par une articulation qui sera détaillée plus loin, éventuellement située sur une bride 4 entourant une partie du moyeu 2. Les rayons 3 sont destinés à soutenir un enroulement de conduite flexible (montrée par la référence 14 de la figure 2) ; afin d'alléger la structure, il est possible de prévoir (comme représenté sur la figure 1) que la section des rayons diminue, régulièrement ou par degrés, à mesure qu'on s'éloigne du moyeu 2, et que la section du rayon est soumise à un effort moindre en raison du plus faible nombre de spires supportées.Figure 1 shows a wheel or spider 1 consisting of a cylindrical hub 2, around which extends in a radial plane a plurality of arms radial or spokes 3. Spokes are connected to hub 2 by an articulation which will be detailed later, possibly located on a flange 4 surrounding a part of the hub 2. Spokes 3 are intended for supporting a flexible pipe winding (shown by reference 14 in FIG. 2); in order to lighten the structure, it is possible to predict (as shown in FIG. 1) that the radius section decreases, regularly or by degrees, as one moves away of hub 2, and that the radius section is subjected to a less effort due to the lower number of supported turns.

Comme le montre la figure 2, un ensemble d'araignées 1 est associé à une palette 10 constituée d'une base 11 à rotation motorisée par rapport à un socle 12 disposé sur le pont du bateau. La base 11 pourrait comporter une colonne de centrage sur laquelle viennent s'enfiler les moyeux 2 des araignées empilées, mais de préférence les moyeux sont auto-empilables comme décrit plus loin. La base 11 comporte, espacées circonférentiellement sur sa périphérie, des barres verticales 20 démontables qui (cf. aussi figure 5) s'intercalent entre les bras 3 des araignées 1. Les barres 20 sont situées sur un cylindre enveloppant le cylindre constitué de l'empilement des moyeux 2 et des brides 4. Les barres 20 servent de guidage d'empilement, et assurent aussi la stabilité de l'empilement en mer. De plus, lorsque la base 11 tourne, les barres 20 peuvent contribuer à entraíner en rotation les araignées superposées.As shown in Figure 2, a set of spiders 1 is associated with a palette 10 made up of a base 11 with motorized rotation relative to a base 12 arranged on the deck of the boat. Base 11 could include a centering column on which thread the hubs 2 of the stacked spiders, but preferably the hubs are self-stacking as described below. Base 11 has, spaced circumferentially on its periphery, bars 20 removable verticals (see also figure 5) are inserted between the arms 3 of the spiders 1. The bars 20 are located on a cylinder enveloping the cylinder consisting of the stack of hubs 2 and flanges 4. The bars 20 serve as stacking guides, and also ensure the stability of the stack at sea. In addition, when the base 11 rotates, the bars 20 can help to rotate the superimposed spiders.

On a représenté sur la figure 2 deux araignées superposées, mais on peut naturellement en prévoir plus. Chaque araignée 1 peut comporter un seul ou plusieurs tronçons enroulés successivement ou superposés de conduite 14. Les conduites peuvent avoir des diamètres différents. Ainsi on a représenté sur l'araignée supérieure une conduite 14' de diamètre plus grand que celui de la conduite 14 ; pour tenir compte de son plus grand rayon minimal de courbure sans déformation, on a prévu sur les rayons 3 de l'araignée supérieure de placer des butées intérieures d'enroulement 16 définissant le diamètre minimal d'enroulement. Ces butées 16 peuvent être soudées aux rayons 3 ou être prévues coulissantes et escamotables sur les rayons. De même, des butées extérieures d'enroulement 15 peuvent être prévues à l'extrémité des rayons 3, de préférence escamotables grâce à une articulation appropriée.We have shown in Figure 2 two superimposed spiders, but you can naturally plan more. Each spider 1 can have only one or several sections wound successively or superimposed 14. The pipes may have different diameters. So we represented on the spider upper 14 'larger diameter pipe than that of line 14; to account for her greatest minimum radius of curvature without deformation, we have planned on the spokes 3 of the upper spider place internal winding stops 16 defining the minimum winding diameter. These stops 16 can be welded to spokes 3 or be provided sliding and retractable on the shelves. Likewise, external winding stops 15 can be provided at the end of spokes 3, preferably retractable thanks to an appropriate articulation.

La figure 3 illustre notamment un mode de réalisation de moyeux 2 auto-empilables ; ils comportent à leur parties supérieure et inférieure des reliefs complémentaires emboítables 5 et 6 et auto-centrables, en particulier des portées coniques. On y voit aussi l'articulation 7 entre les rayons 3 et la bride 4 entourant le moyeu. Ces articulations sont prévues avec blocage de manière que les bras déployés de l'araignée puissent rester dans un plan radial. On peut prévoir des anneaux de levage 8 disposés sur la bride 4 (ou ailleurs du moment qu'ils ne gênent pas l'empilage de plusieurs araignées) destinés à la manutention des araignées.Figure 3 illustrates in particular a mode of production of self-stacking hubs 2; they feature at their upper and lower parts of complementary nestable reliefs 5 and 6 and self-centering, in particular conical bearings. We also sees the articulation 7 between the spokes 3 and the flange 4 surrounding the hub. These joints are provided with locking so that the arms deployed of the spider can remain in a radial plane. We can provide lifting rings 8 arranged on the flange 4 (or elsewhere as long as they do not interfere stacking several spiders) intended for handling spiders.

Dans une variante de l'invention, on empile les araignées non plus sur une palette spécifique 10 mais sur un carrousel existant 10A représenté sur la figure 2A avec son socle 12A sur lequel est monté le large plateau rotatif 11A, présentant une colonne centrale 13A et une cage externe 17A.In a variant of the invention, we stack spiders either on a specific pallet 10 but on an existing carousel 10A represented on the Figure 2A with its base 12A on which the large rotary table 11A, with a column central unit 13A and an external cage 17A.

Les dimensions respectives des divers éléments constitutifs d'une araignée n'ont pas été respectées sur les dessins et diffèrent selon leur utilisation sur carrousel ou sur palette spécifique. A titre d'ordre de grandeur, le rayon intérieur r du moyeu 2 utilisé sur carrousel peut être de 3 m, tandis que le rayon R d'un bras déployé peut être de 7 à 10m par exemple. La hauteur h disponible entre le dessus du plan radial formé par les bras 3 déployés d'une araignée et l'araignée superposée est d'au moins 0,65 m pour permettre l'enroulement des conduites ayant ce diamètre. Pour une araignée utilisée sur palette spécifique 10, on préfère réduire le rayon du moyeu 2 à 1,10m, de manière qu'une fois les bras repliés, l'araignée puisse tenir dans un conteneur de taille standard (2,2 x 2,2 x 5,5 m3), ce qui en facilite le rapatriement à vide.The respective dimensions of the various components of a spider have not been observed in the drawings and differ according to their use on a carousel or on a specific pallet. As an order of magnitude, the inner radius r of the hub 2 used on the carousel can be 3 m, while the radius R of a deployed arm can be 7 to 10 m for example. The height h available between the top of the radial plane formed by the arms 3 deployed of a spider and the superimposed spider is at least 0.65 m to allow the winding of the pipes having this diameter. For a spider used on a specific pallet 10, it is preferable to reduce the radius of the hub 2 to 1.10 m, so that once the arms are folded, the spider can fit in a standard size container (2.2 x 2, 2 x 5.5 m 3 ), which facilitates repatriation when empty.

La figure 4 montre un autre exemple de réalisation dans lequel le bras 3 est constitué de deux parties 3a, 3b articulées entre elles par une articulation 9, permettant à la partie radialement extérieure 3b du bras de se rabattre le long de la partie radialement intérieure 3a du bras, laquelle est elle-même représentée dans sa position repliée parallèlement à l'axe du moyeu 2. Figure 4 shows another example of embodiment in which the arm 3 consists of two parts 3a, 3b hinged together by a hinge 9, allowing the radially outer part 3b of the arm to fold down along the radially part inner 3a of the arm, which is itself shown in its folded position parallel to hub axis 2.

L'empilement des araignées en position repliée (notamment dans le cas des araignées pour carrousel) est possible en décalant d'un certain angle les bras repliés d'une araignée sur l'autre. Alternativement, il peut être préférable que les bras 3 ne soient pas repliés complètement parallèlement à l'axe du moyeu mais selon une orientation oblique compatible avec l'empilement.Stacking spiders in position folded (especially in the case of spiders for carousel) is possible by shifting by a certain angle arms folded from one spider to the other. Alternately, it may be preferable that arms 3 do not are not folded completely parallel to the axis of the hub but in a compatible oblique orientation with stacking.

La version montrée sur la figure 5 se distingue par le fait que les bras 3 comportent une première partie radialement intérieure 3a au bout de laquelle s'articule deux parties ramifiées 3c susceptibles de prendre deux positions distinctes dans le plan radial de support de l'enroulement : une position déployée telle que représentée en traits pleins, où les parties 3c prolongent obliquement les parties radiales 3a, et portent la capacité d'enroulement au maximum (par exemple 2000 tonnes pour une palette complète de cinq roues), et une position rentrée ou repliée le long des parties 3a, ce qui correspond à une capacité d'enroulement moindre (par exemple 900 tonnes pour la palette complète). On observera que dans leur position déployée, les parties ramifiées 3c permettent de maintenir la longueur des arcs d'enroulement de conduite entre deux parties de support 3c à une valeur ne donnant pas lieu à l'apparition d'une flèche préjudiciable de la conduite entre supports.The version shown in Figure 5 is distinguishes by the fact that the arms 3 have a first radially inner part 3a at the end of which is articulated two branched parts 3c susceptible to take two separate positions in the radial plane of winding support: a position deployed as shown in solid lines, where the parts 3c obliquely extend the radial parts 3a, and bring the winding capacity to the maximum (for example 2000 tonnes for a full pallet of five wheels), and a stowed or folded position along parts 3a, which corresponds to a capacity less winding (for example 900 tonnes for the full palette). We will observe that in their position deployed, the branched parts 3c allow maintain the length of the winding arcs of pipe between two support parts 3c at a value not giving rise to the appearance of an arrow detrimental to the conduct between supports.

Diverses modifications peuvent être prévues sans sortir du cadre de l'invention. On peut prévoir que les parties 3c sont escamotables à l'intérieur des parties 3a lorsqu'on retourne les araignées à vide. Des butées d'enroulement 15 et 16, éventuellement repliables, peuvent être prévues sur les bras 3. La butée intérieure 16 est avantageusement réglable en position radiale de manière à pouvoir ajuster le diamètre d'enroulement de la conduite.Various modifications can be planned without departing from the scope of the invention. We can predict that the parts 3c are retractable inside the parts 3a when the spiders are returned empty. of the winding stops 15 and 16, possibly foldable, can be provided on the arms 3. The stop interior 16 is advantageously adjustable in position radial so that the diameter can be adjusted pipe winding.
