Description

L'invention concerne un procédé de transport, d'installation et de démantèlement d'un pont d'une plate-forme pétrolière d'exploitation en mer.The invention relates to a method for transporting, installing and dismantling a bridge of an offshore oil platform.

Pour l'exploitation pétrolière, il est connu de placer au-dessus d'un gisement pétrolifère, une plate-forme pétrolière qui comprend un pont portant notamment des équipements d'exploitation et des locaux d'habitation.For oil exploitation, it is known to place over an oil field, an oil platform that includes a bridge including operating equipment and living quarters.

Le pont est soutenu par un ensemble de support formé par des jambes en appui sur le fond marin ou par une colonne flottante ancrée sur le sol marin.The bridge is supported by a support assembly formed by legs resting on the seabed or by a floating column anchored on the sea floor.

Pour transporter, installer et démanteler un pont d'une plate-forme pétrolière, plusieurs méthodes sont utilisées.To transport, install and dismantle a deck of an oil platform, several methods are used.

Une méthode connue consiste à utiliser des grues de levage montées sur des barges pour transférer le pont de la plate-forme de la barge de transport sur l'ensemble de support. Cette méthode qui est jusqu'à maintenant la plus répandue présente des limitations. En effet, la première de ces limitations est la capacité des grues de levage qui peut imposer de réaliser le pont en plusieurs éléments ce qui augmente de manière importante le coût de fabrication de ce pont et le coût de l'installation et du démantèlement dudit pont de la plate-forme pétrolière. La seconde limitation réside dans le fait que cette méthode impose d'avoir une fenêtre de temps favorable relativement importante pour pouvoir réaliser cette opération en mer dans de bonnes conditions.One known method is to use barge-mounted lifting cranes to transfer the deck of the transport barge platform onto the support assembly. This method, which until now is the most widespread, has limitations. Indeed, the first of these limitations is the capacity of the hoisting cranes which can impose to realize the bridge in several elements which significantly increases the manufacturing cost of this bridge and the cost of the installation and dismantling of said bridge of the oil rig. The second limitation lies in the fact that this method requires to have a relatively large window of time to be able to carry out this operation at sea in good conditions.

Une autre méthode connue consiste à installer le pont de la plateforme pétrolière en un seul bloc sur l'ensemble de support en le faisant flotter. Ensuite, le pont est disposé sur cet ensemble de support soit par un système de ballastage, soit par un système mécanique.Another known method is to install the deck of the oil platform in one block on the support assembly by floating it. Then, the bridge is disposed on this support assembly either by a ballast system or by a mechanical system.

Le principal inconvénient des systèmes de ballastage ou déballastage réside dans le fait qu'ils dépendent des conditions de mer ce qui rend difficilement leur utilisation dans des zones où les fenêtres de temps favorable sont relativement courtes.The main disadvantage of ballasting or deballasting systems is that they depend on sea conditions, which makes it is difficult to use them in areas where windows of favorable weather are relatively short.

D'une manière générale, les systèmes mécaniques utilisés jusqu'à présent pour réaliser l'installation et le démantèlement d'un pont d'une plate-forme pétrolière sont plus rapides que les systèmes de ballastage ou déballastage.In general, the mechanical systems used to date for the installation and dismantling of a deck of an oil rig are faster than ballast or deballasting systems.

Par ailleurs, on connaît dans le FR-A-2 837 461 , une structure de transport, d'installation et de démantèlement d'un pont d'une plate-forme pétrolière fixe qui comporte un coque flottante en forme de U équipée d'au moins trois jambes de levage de cette coque et adaptées pour prendre appui sur le fond marin et une navette déplaçable le long desdites jambes par la coque et destinée à être appliquée sur la face inférieure d'un pont d'une plate-forme pétrolière.Moreover, we know in the FR-A-2,837,461 , a structure for transporting, installing and dismantling a bridge of a fixed oil platform which comprises a U-shaped floating hull equipped with at least three lifting legs of this hull and adapted to take support on the seabed and a shuttle movable along said legs by the hull and intended to be applied on the underside of a deck of an oil platform.

Ainsi, lors de l'installation ou du démantèlement du pont de la plate-forme, les jambes sont abaissées pour prendre appui sur le fond marin et le pont est soulevé par l'intermédiaire de la navette qui est elle même soulevée par la coque.Thus, during the installation or dismantling of the deck of the platform, the legs are lowered to bear on the seabed and the deck is raised via the shuttle which is itself raised by the hull.

Dans le cas de gisements pétrolifères en eau profonde, ce type de structure ne peut être utilisé pour l'installation ou le démantèlement du pont d'une plate-forme pétrolière du fait que les jambes doivent être en contact avec le fond pour soulever le pont ce qui est impossible pour de tels gisements.In the case of deep-water oilfields, this type of structure can not be used for the installation or dismantling of the deck of an oil platform because the legs must be in contact with the bottom to lift the deck which is impossible for such deposits.

L'invention a pour but d'éviter ces inconvénients en proposant une structure qui permet le transport, l'installation ou le démantèlement d'une plateforme pétrolière fixe ou flottante, aussi bien en eau peu profonde qu'en eau profonde.The invention aims to avoid these disadvantages by providing a structure that allows the transport, installation or dismantling of a fixed or floating oil platform, both in shallow water in deep water.

  • à amener dans la structure et au-dessous du pont un élément de transport,
  • à descendre les navettes par l'intermédiaire des jambes pour poser le pont sur l'élément de transport,
  • à abaisser les jambes et les navettes pour libérer le pont de la structure, et
  • à retirer le pont de la structure par l'élément de transport.

D'une manière générale, l'invention s'applique pour tout type de plate-forme pétrolière fixe ou flottante en eau peu profonde ou en eau profonde.In general, the invention applies to any type of fixed or floating oil platform in shallow water or in deep water.

Dans ce qui suit, la description sera faite par rapport à une plateforme flottante pour l'exploitation pétrolière en eau profonde.In what follows, the description will be made with respect to a floating platform for deep-water oil exploitation.

Sur la Fig. 1, on a représenté schématiquement une plate-forme pétrolière flottante désignée dans son ensemble par la référence 1 et qui comprend, de manière classique, un pont 2 pourvu des équipements d'exploitation et des locaux d'habitation habituels. Ce pont 2 est monté sur une colonne support 3 formant un flotteur et qui est fixée sur le fond marin, non représenté, par des lignes d'ancrage 4.On the Fig. 1 there is schematically a floating oil platform generally designated 1 and which comprises, conventionally, a bridge 2 provided with the usual operating equipment and living quarters. This bridge 2 is mounted on a support column 3 forming a float and which is fixed on the seabed, not shown, by anchoring lines 4.

Pour assurer le transport, l'installation (comissioning) et le démantèlement (decommissioning) du pont 2 de la plate-forme pétrolière 1 d'un élément de transport 5 (Fig. 8A), comme par exemple une barge, jusqu'à la colonne support 3 ou inversement, on utilise une structure désignée par la référence générale 10 et représentée sur les Figs. 2 et 3.To ensure the transportation, installation (comissioning) and decommissioning of bridge 2 of the oil platform 1 of a transport element 5 ( Fig. 8A ), such as for example a barge, up to the support column 3 or vice versa, a structure designated by the general reference 10 and represented on the Figs. 2 and 3 .

Sur ces figures, les dimensions générales de la structure 10 ainsi que les proportions entre les différents éléments composant cette structure n'ont pas forcément été respectées afin de simplifier la compréhension du dessin.In these figures, the general dimensions of the structure 10 as well as the proportions between the various elements making up this structure have not necessarily been respected in order to simplify the understanding of the drawing.

D'une manière générale, la structure 10 comprend une coque flottante 11 en forme de U comportant deux branches latérales 11a parallèles et opposées, reliées entre elles par une branche centrale 11b. Les deux branches latérales 11 a et la branche centrale 11 b sont flottantes. La coque 11 est équipée de jambes 12 déplaçables verticalement par rapport à cette coque 11 en flottabilité. Dans l'exemple de réalisation représenté sur les Figs. 2 et 3, la coque 11 est équipée de quatre jambes 12 disposées par paire sur chaque branche latérale 11 a de ladite coque 11.In general, the structure 10 comprises a U-shaped floating shell 11 comprising two parallel lateral branches 11a and opposite, interconnected by a central branch 11b. The two lateral branches 11a and the central branch 11b are floating. The hull 11 is equipped with legs 12 movable vertically relative to the hull 11 in buoyancy. In the exemplary embodiment shown on the Figs. 2 and 3 , the hull 11 is equipped with four legs 12 arranged in pairs on each lateral branch 11a of said hull 11.

Comme représenté sur les Figs. 2, 3 et 5, chacune des jambes 12 présente, dans ce mode de réalisation, une section triangulaire. Ces jambes 12 peuvent également présenter une section carrée ou circulaire.As shown on Figs. 2 , 3 and 5 , each leg 12 has, in this embodiment, a triangular section. These legs 12 may also have a square or circular section.

Chaque jambe 12 est formée, de manière classique, de trois membrures 14 reliées entre elles par un treillis de poutrelles métalliques 15 (Fig. 6) et est associée à des moyens mécaniques de déplacement désignés par la référence générale 20 (Figs. 2, 3 et 5) pour chaque jambe 12. Les moyens mécaniques de déplacement 20 sont logés dans une ossature porteuse 16 (Fig. 5), également appelée par les spécialistes "jack-house", qui est supportée par la coque 11.Each leg 12 is formed, in a conventional manner, of three members 14 interconnected by a lattice of metal beams 15 ( Fig. 6 ) and is associated with mechanical displacement means designated by the general reference 20 ( Figs. 2 , 3 and 5 ) for each leg 12. The mechanical displacement means 20 are housed in a supporting frame 16 ( Fig. 5 ), also called by the "jack-house" specialists, who is supported by the hull 11.

Ainsi que représenté sur les Figs: 5 et 6, les moyens mécaniques de déplacement 20 de chaque jambe 12 comprennent, d'une part, deux plaques opposées 21 portées chacune par une membrure 14 de la jambe 12 correspondante et comportant chacune, sur chaque face latérale, une série de dents 22 formant sur les deux membrures 14, une crémaillère double. Les moyens mécaniques de déplacement 20 comprennent également plusieurs ensembles 25 répartis de part et d'autre de chaque plaque 21, suivant la hauteur de celle-ci. Chaque ensemble 25 comprend un groupe moto-réducteur 26 assurant l'entraînement d'un pignon 27 qui engrène avec une série de dents 22 de la plaque 21 correspondante. Dans le mode de réalisation représenté sur les Figs. 4 et 5, les deux séries de dents 22 de chaque plaque 21 sont associées à six pignons 27 entraînés chacun en rotation par un groupe moto-réducteur 26.As shown on the Figs: 5 and 6 the mechanical means of displacement 20 of each leg 12 comprise, on the one hand, two opposite plates 21 each carried by a rib 14 of the corresponding leg 12 and each having, on each lateral face, a series of teeth 22 forming on the two members 14, a double rack. The mechanical displacement means 20 also comprise several sets 25 distributed on either side of each plate 21, according to the height thereof. Each set 25 comprises a geared motor unit 26 for driving a pinion 27 which meshes with a series of teeth 22 of the corresponding plate 21. In the embodiment shown on the Figs. 4 and 5 , the two series of teeth 22 of each plate 21 are associated with six pinions 27 each driven in rotation by a geared motor unit 26.

La structure 10 comporte également, associée à chacune des jambes 12, une navette désignée par la référence générale 30 qui est déplaçable par la jambe 12 correspondante entre une positon basse en appui sur la coque 11 en flottabilité, ainsi que montrée à la Fig. 2 et une position haute, ainsi que représentée à la Fig. 3. Les navettes 30 associées aux jambes 12 sont déplacées simultanément par les jambes 12.The structure 10 also comprises, associated with each of the legs 12, a shuttle designated by the general reference 30 which is movable by the corresponding leg 12 between a low positon resting on the hull 11 in buoyancy, as shown in FIG. Fig. 2 and a high position, as well as represented at Fig. 3 . The shuttles 30 associated with the legs 12 are moved simultaneously by the legs 12.

Ainsi que représenté à la Fig. 4, chaque navette 30 est formée par un corps 31 comportant une branche verticale 32 s'étendant sensiblement parallèlement aux membrures 14 de la jambe 12 correspondante. Dans l'exemple de réalisation représenté sur les Figs. 2 à 4, la branche 32 verticale est formée de deux poutres 32a verticales et parallèles.As represented in Fig. 4 each shuttle 30 is formed by a body 31 having a vertical leg 32 extending substantially parallel to the ribs 14 of the leg 12 corresponding. In the exemplary embodiment shown on the Figs. 2 to 4 vertical branch 32 is formed of two vertical and parallel beams 32a.

La branche 32 est munie, d'une part, à sa partie supérieure, d'une plaque 33 s'étendant sensiblement perpendiculairement à ladite branche 32 et, d'autre part, à sa partie inférieure, d'une semelle 35 horizontale de support du pont 2 de la plate-forme 1, comme on le verra ultérieurement.The branch 32 is provided, on the one hand, at its upper part, with a plate 33 extending substantially perpendicular to said branch 32 and, on the other hand, at its lower part, with a horizontal support sole plate 35 Bridge 2 of the platform 1, as will be seen later.

La plaque 33 comporte une ouverture 34 présentant une section de forme complémentaire à la section transversale de la jambe 12 correspondante et, dans le cas présent, une section triangulaire. La plaque 33 est reliée à la semelle 35 par des poutrelles de rigidification 36.The plate 33 has an opening 34 having a section of complementary shape to the cross section of the corresponding leg 12 and, in this case, a triangular section. The plate 33 is connected to the sole 35 by stiffening beams 36.

Chaque navette 30 est munie de moyens 40 de verrouillage sur la jambe 12 correspondante.Each shuttle 30 is provided with locking means 40 on the corresponding leg 12.

Ces moyens 40 de verrouillage représentés plus en détail sur la Fig. 7 sont formés par au moins une contre-crémaillère 41 et, de préférence, par au moins une contre-crémaillère 41 pour chaque plaque 21. La contre-crémaillère 41 est déplaçable par au moins un organe d'actionnement 42 et, de préférence, par deux organes d'actionnement 42 constitués par exemple par des vérins hydrauliques ou pneumatiques afin de déplacer la contre-crémaillère 41 entre une position escamotée et une position de blocage en prise sur l'une des séries de dents 22 de la jambe 12 correspondante. L'ensemble constitué par la contre-crémaillère 41 et les organes d'actionnement 42 est porté par la plaque 33 de chaque navette 30.These locking means 40 shown in greater detail on the Fig. 7 are formed by at least one counter-rack 41 and, preferably, by at least one counter-rack 41 for each plate 21. The counter-rack 41 is displaceable by at least one actuating member 42 and, preferably, by two actuating members 42 constituted for example by hydraulic or pneumatic cylinders to move the counter-rack 41 between a retracted position and a locking position engaged on one of the series of teeth 22 of the leg 12 corresponding. The assembly consisting of the counter-rack 41 and the actuating members 42 is carried by the plate 33 of each shuttle 30.

Enfin, la coque 11 comporte, au niveau de chaque jambe 12, des moyens 50 de guidage de la navette 30 correspondante entre les positions, respectivement basse (Fig.2) et haute (Fig. 3).Finally, the shell 11 comprises, at each leg 12, means 50 for guiding the corresponding shuttle 30 between the positions, respectively low ( Fig.2 ) and high ( Fig. 3 ).

Comme montré sur ces Figs. 2 et 3, les moyens 50 de guidage de la navette 30 de chaque jambe 12 comprennent deux colonnes 51 verticales s'étendant sensiblement parallèlement à la jambe 12 correspondante. Chaque colonne 51 coopère avec un passage 52 ménagé dans la semelle 35 de la navette 12 et chacun de ces passages 52 présente une section de forme conjuguée à la section de la colonne 51 correspondante. Les deux colonnes 51 sont reliées entre elles par une plaque de liaison 53 s'étendant sensiblement perpendiculairement auxdites colonnes 51 et qui comporte un passage central 54 (Fig. 3) présentant une section de forme complémentaire à la section transversale de la jambe 12 correspondante et, dans le cas présent, une section triangulaire. La plaque de liaison 53 forme un guidage pour la jambe 12 correspondante.As shown on these Figs. 2 and 3 , the means 50 for guiding the shuttle 30 of each leg 12 comprise two vertical columns 51 extending substantially parallel to the corresponding leg 12. Each Column 51 cooperates with a passage 52 formed in the sole plate 35 of the shuttle 12 and each of these passages 52 has a section of shape conjugate to the section of the corresponding column 51. The two columns 51 are interconnected by a connecting plate 53 extending substantially perpendicular to said columns 51 and which comprises a central passage 54 ( Fig. 3 ) having a section of complementary shape to the cross section of the corresponding leg 12 and, in this case, a triangular section. The connecting plate 53 forms a guide for the corresponding leg 12.

Au cours du déplacement de la navette 30 entre la position basse et la positon haute par la jambe 12, la semelle 35 de la navette 30 est guidée par les colonnes 51 et dans la position basse représentée à la Fig. 2, la plaque 31 de la navette 30 est en appui sur l'extrémité supérieure de chaque colonne 51.During the movement of the shuttle 30 between the low position and the high position by the leg 12, the sole 35 of the shuttle 30 is guided by the columns 51 and in the low position shown in FIG. Fig. 2 , the plate 31 of the shuttle 30 bears on the upper end of each column 51.

Selon un mode de réalisation préférentiel, la longueur de la branche centrale 11b de la coque 11 est ajustable en fonction de la largeur du pont 2 de la plate-forme pétrolière 1. Pour cela, cette branche centrale 11 b peut être composée de deux tronçons entre lesquels peut être monté un ou plusieurs tronçons intermédiaires 11 c afin de modifier la longueur de cette branche centrale 11b.According to a preferred embodiment, the length of the central branch 11b of the shell 11 is adjustable as a function of the width of the bridge 2 of the oil platform 1. For this, this central branch 11b can be composed of two sections between which can be mounted one or more intermediate sections 11c to change the length of this central branch 11b.

Le transport et l'installation du pont 2 par la structure 10 sur un site d'exploitation sont réalisés de la façon suivante.The transport and installation of the bridge 2 by the structure 10 on an operating site are carried out as follows.

La structure 10 est amenée en flottaison à proximité du site d'exploitation avec les jambes 12 relevées pour ne pas freiner son déplacement.The structure 10 is floated near the operating site with the legs 12 raised to not slow its movement.

Tout d'abord et comme montré sur la Fig. 8A, un élément de transport par flottaison, comme par exemple une barge 5, amène le pont 2 de la plate forme 1 à proximité de la structure flottante 10. La barge 5 se place entre les deux branches latérales 11a de la coque 11, les jambes 12 de cette coque 11 étant dans une position intermédiaire ou dans une position complètement remontée.First and as shown on the Fig. 8A , a floating transport element, such as a barge 5, brings the bridge 2 of the platform 1 near the floating structure 10. The barge 5 is placed between the two lateral branches 11a of the shell 11, the legs 12 of this shell 11 being in an intermediate position or in a fully raised position.

Ensuite, ces jambes 11 sont abaissées et chaque navette 30 est verrouillée sur la jambe 12 correspondante selon la hauteur de levage, mais de préférence sur l'extrémité supérieure de ladite jambe. Le verrouillage des navettes 30 sur les jambes 12 est réalisé en actionnant les vérins 42 pour que les contre-crémaillères 41 viennent en prise avec les dents 22 adjacentes.Then, these legs 11 are lowered and each shuttle 30 is locked on the corresponding leg 12 according to the lifting height, but preferably on the upper end of said leg. The locking of the shuttles 30 on the legs 12 is achieved by actuating the cylinders 42 so that the counter-racks 41 engage with the teeth 22 adjacent.

Le pont 2 est posé sur les semelles 35 des navettes 30 en ballastant la barge 5 et cette barge 5 est ensuite évacuée. Dans le cas où la barge 5 ne dispose pas de système de ballastage, les navettes 30 sont verrouillées sur les jambes 12 et les jambes 12 sont relevées afin de lever le pont 2 de la barge 5.The bridge 2 is placed on the soles 35 of the shuttles 30 by ballasting the barge 5 and this barge 5 is then evacuated. In the case where the barge 5 does not have a ballast system, the shuttles 30 are locked on the legs 12 and the legs 12 are raised to lift the deck 2 of the barge 5.

Le pont 2 est soulevé par l'intermédiaire des navettes 30 et des jambes 12, la coque 11 de la structure 10 restant en flottabilité. Pour cela, les groupes moto-réducteurs 26 sont actionnés pour entraîner les pignons 27 qui engrènent les séries de dents 22 des plaques 21 de chaque jambe 12 afin de déplacer au moyen des jambes 12, les navettes 30 en position haute de levage du pont 2, comme montrée à la Fig. 8C. Lors du déplacement des jambes 12 pour soulever le pont 2 au moyen des navettes 30, chaque navette 30 est guidée par les colonnes 51 qui glissent dans les passages 52. Ces colonnes 51 permettent également de maintenir les semelles 35 dans une position sensiblement horizontale et d'éviter que les navettes 30 basculent sous le poids du pont 2. La structure 10 supportant le pont 2 est déplacée afin d'amener ce pont 2 au-dessus de son support constitué par la colonne support 3.The bridge 2 is raised via shuttles 30 and legs 12, the shell 11 of the structure 10 remaining buoyant. For this, the geared motor units 26 are actuated to drive the pinions 27 which mesh the series of teeth 22 of the plates 21 of each leg 12 in order to move by means of the legs 12, the shuttles 30 in the raised position of the bridge 2 , as shown in Fig. 8C . During the displacement of the legs 12 to lift the bridge 2 by means of the shuttles 30, each shuttle 30 is guided by the columns 51 which slide in the passages 52. These columns 51 also make it possible to maintain the soles 35 in a substantially horizontal position and avoid that the shuttles 30 fall under the weight of the bridge 2. The structure 10 supporting the bridge 2 is moved to bring the bridge 2 above its support constituted by the support column 3.

Les navettes 30 sont descendues par l'intermédiaire des jambes 12 pour poser le pont 2 sur la colonne support 3, ainsi que montré à la Fig. 8D. Pour effectuer cette opération, les groupes moto-réducteurs 26 sont actionnés en sens inverse afin d'entraîner en rotation les pignons 27 et descendre les jambes 12.The shuttles 30 are lowered through the legs 12 to put the bridge 2 on the support column 3, as shown in FIG. Fig. 8D . To carry out this operation, the geared motor units 26 are actuated in opposite directions in order to drive the gears 27 in rotation and to lower the legs 12.

Au cours de la pose du pont sur la colonne support 3 (Figs. 8D et 8E), cette colonne support 3 s'enfonce progressivement dans l'eau du fait du poids du pont 2. Les jambes 12 et les navettes 30 continuent à descendre pour que le poids du pont 2 soit totalement récupéré par la colonne support 3.During the laying of the bridge on the support column 3 ( Figs. 8D and 8E ), this support column 3 gradually sinks into the water due to the weight of the bridge 2. The legs 12 and the shuttles 30 continue to descend so that the weight of the bridge 2 is fully recovered by the support column 3.

Une fois le pont 2 posé sur la colonne support 3, les jambes 12 sont abaissées ce qui permet de libérer ainsi le pont 2 de la structure 10 (Fig. 8E).Once the bridge 2 is placed on the support column 3, the legs 12 are lowered, thereby freeing the bridge 2 of the structure 10 ( Fig. 8E ).

Cette structure 10 est ensuite évacuée du site d'exploitation.This structure 10 is then removed from the operating site.

Le démantèlement et le transport du pont 2 du site d'exploitation jusqu'à l'élément de transport constitué par la barge 5 sont réalisés en effectuant les opérations inverses qui sont mentionnées brièvement ci-dessous.The dismantling and transport of the bridge 2 from the operating site to the transport element constituted by the barge 5 are carried out by performing the reverse operations which are briefly mentioned below.

Tout d'abord, la coque 11 de la structure flottante 10 est amenée sur le site d'exploitation et les jambes 12 de cette coque 11 sont abaissées. Les navettes 30 sont verrouillées sur les jambes 12 et la coque 11 est déplacée pour amener la colonne support 3 entre les branches latérales 11a de la coque 11 et pour placer les navettes 30 au-dessous du pont 2.First, the hull 11 of the floating structure 10 is brought to the operating site and the legs 12 of the hull 11 are lowered. The shuttles 30 are locked on the legs 12 and the hull 11 is moved to bring the support column 3 between the lateral branches 11a of the hull 11 and to place the shuttles 30 below the deck 2.

Les navettes 30 sont soulevées par l'intermédiaire des jambes 12 au moyen des mécanismes de déplacement 20. Les semelles 35 entrent en contact avec le pont 2 et ce pont 2 est soulevé, puis la structure flottante 10 supportant le pont 2 est déplacée afin de retirer ce pont 2 de la colonne support 3. La barge 5 est amenée entre les branches latérales 11a de la coque 11 et elle est placée au-dessous du pont 2. Les navettes 30 par l'intermédiaire des jambes 12 sont descendues pour poser le pont 2 sur la barge 5 et ces jambes 12 et les navettes 30 sont abaissées afin de libérer le pont 2 de la structure 10, ce pont 2 reposant maintenant sur la barge 5.The shuttles 30 are lifted via the legs 12 by means of the displacement mechanisms 20. The flanges 35 come into contact with the deck 2 and this deck 2 is raised, then the floating structure 10 supporting the deck 2 is moved in order to remove the bridge 2 from the support column 3. The barge 5 is brought between the lateral branches 11a of the hull 11 and is placed below the bridge 2. The shuttles 30 through the legs 12 are lowered to put the bridge 2 on the barge 5 and legs 12 and shuttles 30 are lowered to release the bridge 2 of the structure 10, this bridge 2 now resting on the barge 5.

Ensuite, la barge 5 supportant le pont 2 est évacuée de la structure 10.Then, the barge 5 supporting the bridge 2 is removed from the structure 10.

Sur la Fig. 9, on a représenté une variante de la structure 10. Dans ce mode de réalisation, les extrémités inférieures des deux jambes 12 contiguës, c'est à dire portées par la même branche latérale 11 a de la coque 11 comportent un stabilisateur 60 reliant les deux extrémités inférieures entre elles.On the Fig. 9 a variant of the structure 10 is shown. In this embodiment, the lower ends of the two adjoining legs 12, ie carried by the same lateral branch 11a of the shell 11, comprise a stabilizer 60 connecting the two lower extremities together.

Sur les Figs. 10 à 11, on a représenté une autre variante de la structure 10 montrant respectivement à la Fig. 10 la partie arrière de la structure 10 et aux Figs. 11 et 12 la partie avant de ladite structure 10 par laquelle est introduite la colonne support 3 du pont 2, ainsi qu'on le verra ultérieurement.On the Figs. 10 to 11 there is shown another variant of the structure 10 respectively showing the Fig. 10 the rear part of structure 10 and to Figs. 11 and 12 the front portion of said structure 10 through which is introduced the support column 3 of the bridge 2, as will be seen later.

Sur ces figures, les éléments communs au précédent mode de réalisation ont été désignés par les mêmes références.In these figures, the elements common to the previous embodiment have been designated by the same references.

Dans ce mode de réalisation, la structure 10 est formée par une coque 71 flottante qui présente également la forme générale d'un U et qui comporte deux branches latérales 71 a et une branche centrale 71b reliant les deux branches latérales 71 a.In this embodiment, the structure 10 is formed by a floating shell 71 which also has the general shape of a U and which has two lateral branches 71a and a central branch 71b connecting the two lateral branches 71a.

Les deux branches latérales 71a sont formées par deux flotteurs 72a s'étendant parallèlement l'un par rapport à l'autre et ménageant entre eux un espace libre et la branche centrale 71 b est formée par une poutre transversale 72b portée par lesdites branches latérales 71a, ainsi que montré à la Fig.10. De préférence, la poutre transversale 72 b est constituée par un treillis de tubes 75 reliés entre eux par des éléments longitudinaux 76.The two lateral branches 71a are formed by two floats 72a extending parallel to each other and leaving between them a free space and the central branch 71b is formed by a transverse beam 72b carried by said lateral branches 71a as shown in Fig.10 . Of Preferably, the transverse beam 72b is constituted by a grid of tubes 75 interconnected by longitudinal elements 76.

Les branches latérales 71 a de la structure 10 sont déplaçables par coulissement l'une par rapport à l'autre sur la poutre transversale 72b de façon à régler leur écartement en fonction de la largeur du pont 2.The lateral branches 71a of the structure 10 are displaceable by sliding relative to each other on the transverse beam 72b so as to adjust their spacing as a function of the width of the bridge 2.

Pour cela, chaque flotteur 72a formant chacun une branche latérale 71a comporte des moyens 73 de déplacement sur la poutre transversale 72b formés par exemple par un ensemble comportant par exemple des rails de guidage et un système de pignons-crémaillères, non représenté et de type connu.For this, each float 72a each forming a lateral branch 71a has means 73 for moving the transverse beam 72b formed for example by an assembly comprising for example guide rails and a rack-and-pinion system, not shown and of a known type. .

De plus, chaque flotteur 72a constituant les branches latérales 71a est équipé de moyens de verrouillage, non représentés, sur la poutre transversale 72b de façon à maintenir l'écartement entre ces branches latérales 71 a constant et déterminé.In addition, each float 72a constituting the lateral branches 71a is equipped with locking means, not shown, on the transverse beam 72b so as to maintain the spacing between these lateral branches 71a constant and determined.

Ainsi que montré sur les Figs. 11 et 12, la coque 71 comporte, au niveau de sa partie ouverte, c'est à dire à l'opposé de la branche centrale 71 b, une porte désignée dans son ensemble par la référence générale 80.As shown on the Figs. 11 and 12 , the shell 71 comprises, at its open portion, that is to say opposite the central branch 71b, a door generally designated by the general reference 80.

Cette porte 80 est formée de deux tronçons de poutre 81 opposés et déplaçables par coulissement chacun sur un flotteur 72a.This door 80 is formed of two beam sections 81 opposite and movable by sliding each on a float 72a.

Les deux tronçons de poutre 81 sont déplaçables entre une positon fermée de l'entrée de la structure 10, comme montrée à la Fig. 11 dans laquelle ils sont rapprochés et en contact l'un avec l'autre et une position écartée, comme représentée à la Fig. 12 dans laquelle ils libèrent l'entrée de la structure 10 pour le positionnement de la colonne de support 3 au-dessous du pont 2.The two beam sections 81 are movable between a closed position of the entrance of the structure 10, as shown in FIG. Fig. 11 in which they are brought together and in contact with each other and a separated position, as shown in FIG. Fig. 12 in which they release the input of the structure 10 for the positioning of the support column 3 below the bridge 2.

Pour cela, chaque flotteur 72a constituant chacun une branche latérale 71a de la coque 71 comporte des moyens 82 de déplacement de chaque tronçon de poutre 81. Ces moyens 82 sont constitués par exemple par un ensemble comportant des rails de guidage et un système pignons-crémaillères ou par tout autre moyen de type connu.For this, each float 72a each constituting a lateral branch 71a of the shell 71 comprises means 82 for moving each beam section 81. These means 82 consist for example of a set comprising guide rails and a rack-and-pinion system. or by any other means of known type.

Enfin, chaque flotteur 72a comporte aussi des moyens de verrouillage, non représentés, du tronçon de poutre 81 correspondant dans la positon fermée ou dans la position ouverte.Finally, each float 72a also comprises locking means, not shown, of the beam section 81 corresponding in the closed position or in the open position.

Comme dans le précédent mode de réalisation, la coque 71 est également équipée de jambes 12 déplaçables verticalement par rapport à ladite coque 71 en flottabilité au moyen de mécanismes de déplacement et, associée à chacune desdites jambes, une navette 30 destinée à être appliquée sur la face inférieure du pont 2 et déplaçable par la jambe 12 correspondante entre une position basse sur la coque 71 en flottabilité et une position haute de levage du pont 2 de la plateforme 1, chaque navette 30 étant munie de moyens de verrouillage sur la jambe 12 correspondante.As in the previous embodiment, the shell 71 is also equipped with legs 12 movable vertically relative to said hull 71 in buoyancy by means of displacement mechanisms and, associated with each of said legs, a shuttle 30 intended to be applied on the lower face of the bridge 2 and movable by the corresponding leg 12 between a low position on the hull 71 in buoyancy and a high lifting position of the bridge 2 of the platform 1, each shuttle 30 being provided with locking means on the corresponding leg 12.

Le transport et l'installation du pont 2 ainsi que le démantèlement de ce pont 2 avec la coque 71 sont réalisés de manière identique au précédent mode de réalisation, à l'exception qu'il est nécessaire d'ouvrir et de fermer la porte 80 pour la pose du pont 2 sur les navettes 30 et également pour le positionnement de la colonne de support 3 au-dessous du pont 2.The transport and the installation of the bridge 2 as well as the dismantling of this bridge 2 with the shell 71 are carried out identically to the previous embodiment, with the exception that it is necessary to open and close the door 80 for laying the bridge 2 on the shuttles 30 and also for the positioning of the support column 3 below the deck 2.

Dans ce mode de réalisation, la rigidité de la coque 11 est obtenue par la poutre transversale 72b constituant la branche centrale 71b de la coque 71 et également par la porte 80, en position de fermeture.In this embodiment, the rigidity of the shell 11 is obtained by the transverse beam 72b constituting the central branch 71b of the shell 71 and also by the door 80, in the closed position.

Dans cette position de fermeture de la porte 80, les deux tronçons de poutre 81 sont verrouillés entre eux par des moyens appropriés, de type con nu, non représentés.In this closed position of the door 80, the two beam sections 81 are locked to each other by appropriate means, of the con nu type, not shown.

Les deux branches latérales 71 a formées par les deux flotteurs 72a peuvent être désolidarisées de la branche centrale 71b permettant ainsi de réduire l'espace nécessaire pour le stockage de ces branches.The two lateral branches 71 formed by the two floats 72a can be detached from the central branch 71b thus reducing the space required for the storage of these branches.

La structure selon l'invention présente l'avantage de pouvoir transporter, installer et démanteler un pont d'une plate-forme pétrolière en eau peu profonde ou en eau profonde, sans aucune modification et en toute sécurité.The structure according to the invention has the advantage of being able to transport, install and dismantle a deck of an oil platform in shallow water or in deep water, without any modification and in complete safety.
