Description

Dispositif repliable et empilable d'enroulement de conduites tubulaires flexibles Foldable and stackable device for winding flexible tubular conduits
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. 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.The pipes in question are in particular the pipes for transporting hydrocarbons laid underwater from laying ships. Such pipes are well known and can be continuous or made of assembled sections. Their rigidity is variable and here we mean by flexible pipes simply to indicate that they can be rolled up without plastic deformation into coils of large diameter. Flexible tubular conduits are manufactured in great length ashore and must then be transported to the installation site, either directly on the installation vessel when the distance between the shore site and the installation site is not too great, or generally on an intermediate transport barge which will take them to the laying vessel.
On connaît 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 known two types of quayside and onboard containers for winding pipes, namely coils and carousels. A reel is made up of a horizontal winding axis held between two cheeks, all of an average size (for example 9x9x5 m 3 ) and a related capacity (190 tonnes), while a carousel is defined by a large central column winding 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. There are three solutions for loading a pipe from the quay to the ship: by reel transport (solution hereinafter called reel-reel), or by transfer of the pipe from reels to the quay on a carousel on board (hereinafter reel-carousel solution), or by transfer of the pipe from a carousel alongside on a carousel on board (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 relati- ve ent 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 drawbacks of the coils are on the one hand that their small diameter requires the pipes to be fairly flexible (that they allow a relatively small minimum bending radius), and that their coiled length is not very great. If the pipe is in reels on board (reel-to-reel solution), the total length on board is average, and the cost of empty reel of the reels is high, taking into account the space lost. On the other hand, the reel-reel solution is particularly flexible during loading at the quay, and loading takes place quickly and safely.
Dans la solution bobine-carrousel, la lon- gueur totale embarquée est plus grande, mais le transfert de bobines à carrousel est long (ce qui entraîne 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. 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 1 ' enroulement . Le problème du retour à vide n'est pas non plus résolu.In the reel-to-carousel solution, the total on-board length is greater, but the transfer from reels to carousel is long (which entails costs of immobilizing the boat) and induces risks of twisting the pipe. In addition, the empty return of the boat carousel is expensive. The carousel-carousel solution makes it possible to embark on pipes that are both considerably longer and possibly less flexible, but not only is the loading operation, as in the previous case, slow and not very flexible, but risks of total blockage of production is not excluded in case of problems during winding. The problem of the empty return is not resolved either.
On connaît dans le cadre de 1 ' 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 1 ' invention .Coils with two flanges connected by a hub are known in the context of winding and transporting cables or the like. medium dimensions, partially foldable. For example, patent FR 2 698 623 A shows a coil with two flanges, the particularity of which is that the flanges can be folded down along a cord. According to documents US Pat. No. 5,649,677 A, US 5,547,147 A, EP 0 745 549 A or DE 35 36 555 A, on the contrary, the hub is foldable. These solutions, which only provide a fairly small gain in space in the radial direction of the flanges, cannot be transposed to the field of coils and large carousels concerned by the invention.
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 most of the drawbacks of known solutions without losing the advantages.
Selon l'invention, on propose un dispositif d'enroulement de conduite tubulaire flexible, du type comportant au moins une roue d'enroulement constituée d'un moyeu d'enroulement et de rayons partant du moyeu dans un plan radial , caractérisé en ce que les rayons sont articulés sur le moyeu de façon à pouvoir être repliés vers 1 ' axe du moyeu , ce qui permet de diminuer considérablement le volume de la roue à vide . 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.According to the invention, a flexible tubular pipe winding device is proposed, of the type comprising at least one winding wheel constituted by a winding hub and spokes extending from the hub in a radial plane, characterized in that the spokes are articulated on the hub so that they can be folded back towards the axis of the hub, which makes it possible to considerably reduce the volume of the idle wheel. Advantageously, each spoke has over its length one or more articulations allowing it to be folded back on itself, which further reduces the volume of the idle wheel.
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 spoke has two branched articulated parts capable of giving, when they are deployed in said radial plane, a very large different winding capacity.
Les roues de l'invention peuvent être empilées sur un carrousel de navire existant, mais selon un aspect très avantageux de l'invention, plusieurs roues sont associées à 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.The wheels of the invention can be stacked on an existing ship's carousel, but according to a very advantageous aspect of the invention, several wheels are associated with a specific stacking pallet placed on the deck of the boat, which may or may not include a column for centering the winding wheels. The pallet is preferably motorized to allow the hose to unwind under the same conditions as with a conventional carousel.
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 bras. 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.It is advantageous that the wheel hub is self-stacking. It is also advantageous if the hub of the wheels is of a size allowing, near folding of the arms, to transport the wheel in a container of standard size. It is also advantageous to provide at least one internal winding stop, preferably radially adjustable, and / or external is provided on the arms. Thanks to these characteristics, it is possible to manipulate the winding wheels using quay cranes or on board individually with the speed, modularity and flexibility of handling conventional coils, but without being limited. flexibility because the wheels can have a diameter on the order of that of a conventional carousel and not a spool. The wheels with their winding are stacked on board on the associated pallet and form a carousel with advantages comparable to those of a conventional carousel.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description suivante de plusieurs exemples de réalisation, se référant aux dessins annexés sur lesquels : - la figure 1 est une vue en perspective schématique d'une roue conforme à l'invention,Other characteristics and advantages of the invention will appear on reading the following description of several embodiments, referring to the attached drawings in which: - Figure 1 is a schematic perspective view of a wheel according to 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 radial arms or spokes 3. The spokes are connected to the hub 2 by an articulation which will be detailed later , possibly located on a flange 4 surrounding a part of the hub 2. The spokes 3 are intended to support a flexible pipe winding (shown by the reference 14 in FIG. 2); in order to lighten the structure, it is possible to provide (as shown in FIG. 1) that the section of the spokes decreases, regularly or by degrees, as one moves away from the hub 2, and that the section of the spoke is subjected to less effort due to the lower number of supported coils.
Comme le montre la figure 2, un ensemble d'araignées 1 est associé à une palette 10 constituée d'une base 11 a 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 circonférentielle ent 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'empi- lement, et assurent aussi la stabilité de l'empilement en mer. De plus, lorsque la base 11 tourne, les barres 20 peuvent contribuer à entraîner en rotation les araignées superposées.As shown in Figure 2, a set of spiders 1 is associated with a pallet 10 consisting of a base 11 with motorized rotation relative to a base 12 disposed on the deck of the boat. The 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. The base 11 comprises, circumferentially spaced ent on its periphery, removable vertical bars 20 which (cf. also FIG. 5) are inserted between the arms 3 of the spiders 1. The bars 20 are located on a cylinder enveloping the cylinder made up of the stack of hubs 2 and flanges 4. The bars 20 serve as a stack guide, and also provide the stability of the stack at sea. In addition, when the base 11 rotates, the bars 20 can contribute to driving the superimposed spiders in rotation.
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'arai- gnée 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 définiε- εant 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.There are shown in Figure 2 two superimposed spiders, but we can naturally predict more. Each spider 1 can comprise a single or several sections wound successively or superimposed of pipe 14. The pipes can have different diameters. Thus there is shown on the upper spool a pipe 14 'of diameter larger than that of the pipe 14; to take account of its greatest minimum radius of curvature without deformation, provision has been made on the spokes 3 of the upper spider to place internal winding stops 16 defined with the minimum winding diameter. These stops 16 can be welded to the spokes 3 or be provided sliding and retractable on the spokes. Likewise, external winding stops 15 can be provided at the end of the spokes 3, preferably retractable by means of 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 emboîtables 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.FIG. 3 illustrates in particular an embodiment of self-stacking hubs 2; they have at their upper and lower parts complementary nestable reliefs 5 and 6 and self-centering, in particular conical bearing surfaces. We also see the joint 7 between the spokes 3 and the flange 4 surrounding the hub. These joints are provided with locking so that the deployed arms of the spider can remain in a radial plane. It is possible to provide lifting rings 8 arranged on the flange 4 (or elsewhere as long as they do not interfere with the stacking of several spiders) intended for the handling of 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. 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 1 ' 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.In a variant of the invention, the spiders are no longer stacked on a specific pallet 10 but on an existing carousel 10A shown in FIG. 2A with its base 12A on which is mounted the large rotary plate 11A, having a central column 13A and an external cage 17A. 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 internal 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 preferred 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 articu- lation 9, permettant à la partie radialement extérieure 3b du bras de se rabattre le long de la partie radialement intérieure 3b du bras, laquelle est elle-même représentée dans sa position repliée parallèlement à 1 ' axe du moyeu 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. Alterna- tivement, 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 1 ' empi1ement .Figure 4 shows another embodiment in which the arm 3 consists of two parts 3a, 3b hinged together by an articulation 9, allowing the radially outer part 3b of the arm to fold down along the radially part inside 3b of the arm, which is itself shown in its folded position parallel to the axis of the hub 2. Stacking the spiders in the folded position (especially in the case of carousel spiders) is possible by shifting the folded arms from one spider to the other by a certain angle. Alternatively, it may be preferable that the arms 3 are not folded completely parallel to the axis of the hub but in an oblique orientation compatible with the encroachment.
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 radialesThe version shown in Figure 5 is distinguished 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 capable of taking two distinct positions in the radial plane of support for the winding : a deployed position as shown in solid lines, where the parts 3c obliquely extend the radial parts
3a, et portent la capacité d'enroulement au maximum3a, and bring the winding capacity to the 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.(for example 2000 tonnes for a full pallet of five wheels), and a retracted or folded position along the parts 3a, which corresponds to a lower winding capacity (for example 900 tonnes for the full pallet). It will be observed that in their deployed position, the branched parts 3c make it possible to maintain the length of the winding arcs of the pipe between two support parts 3c at a value which does not give rise to the appearance of a detrimental arrow in the pipe 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 replia- bles, 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 provided without departing from the scope of the invention. Provision can be made for the parts 3c to be retractable inside the parts 3a when the spiders are returned empty. Winding stops 15 and 16, optionally foldable, can be provided on the arms 3. The internal stop 16 is advantageously adjustable in position radial so that the winding diameter of the pipe can be adjusted.
