Description

Ensemble comprenant une structure flottante insubmersible et un dispositif d'accouplement au fond marin, et procédé d'amarrage correspondant. An assembly comprising an unsinkable floating structure and a coupling device to the seabed, and corresponding mooring method.
La présente invention concerne un ensemble comprenant une structure flottante insubmersible.The present invention relates to an assembly comprising an unsinkable floating structure.
L'invention s'applique, en particulier, à l'amarrage de bateaux ou d'embarcations quelconques.The invention applies, in particular, to the mooring of boats or any boat.
L'amarrage des bateaux se fait traditionnellement dans les ports ou à des bouées d'amarrage, appelées aussi « corps morts », et n'offrant qu'une place de mouillage par bouée.The mooring of boats is traditionally done in harbors or mooring buoys, also called "dead bodies", and offering only one mooring place per buoy.
Toutefois, le nombre de places d'amarrage ainsi offert est insuffisant.However, the number of berths thus offered is insufficient.
Ainsi, en France, le nombre de bateaux de plaisance immatriculés est de 841.000, alors que le nombre d'emplacements dans les ports est de 165.000 et qu'il existe seulement 60.000 bouées d'amarrage.Thus, in France, the number of pleasure craft registered is 841,000, while the number of locations in the ports is 165,000 and there are only 60,000 mooring buoys.
Afin de désengorger les ports, il est également possible de stationner à terre les bateaux. Toutefois, cette solution, qualifiée parfois de port à sec, offre également un nombre de places insuffisant, et s'avère en outre coûteuse et peu pratique à mettre en oeuvre.In order to unclog the ports, it is also possible to park the boats ashore. However, this solution, sometimes referred to as dry port, also offers an insufficient number of places, and is also expensive and impractical to implement.
En effet, il faut mettre son bateau à l'eau à chaque sortie par l'intermédiaire d'une cale de mise à l'eau dont l'utilisation est payante.Indeed, it is necessary to put his boat in the water with each exit by means of a launching wedge whose use is paying.
En outre, durant la période estivale, les cales de mise à l'eau sont fortement encombrées.In addition, during the summer, the launching wedges are heavily congested.
Un but de l'invention est de résoudre ce problème en permettant, simplement et à coût réduit, de stationner un nombre plus important de bateaux.An object of the invention is to solve this problem by allowing, simply and at reduced cost, to park a larger number of boats.
A cet effet, l'invention a pour objet un ensemble selon la revendication 1.For this purpose, the subject of the invention is an assembly according to claim 1.
Selon des modes particuliers de réalisation, l'ensemble peut comprendre l'une ou plusieurs des caractéristiques des revendications 2 à 15, prise(s) isolément ou selon toutes les combinaisons techniquement possibles.According to particular embodiments, the assembly may comprise one or more of the features of claims 2 to 15, taken in isolation or in any technically possible combination.
L'invention a également pour objet un procédé d'amarrage selon la revendication 16. L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et faite en se référant aux dessins annexés, sur lesquels :The invention also relates to a docking method according to claim 16. The invention will be better understood on reading the description which follows, given solely by way of example, and with reference to the accompanying drawings, on which ones :
- la figure 1 est une vue schématique de dessus d'un ensemble selon l'invention sur lequel des bateaux ont été amarrés, - la figure 2 est une vue schématique en coupe du dispositif d'accouplement de l'ensemble de la figure 1 ,FIG. 1 is a diagrammatic view from above of an assembly according to the invention on which boats have been moored; FIG. 2 is a diagrammatic sectional view of the coupling device of the assembly of FIG. 1,

- la figure 5 est une vue schématique de dessus illustrant une deuxième variante de réalisation d'une structure flottante pour l'ensemble de la figure 1 , - les figures 6 et 7 sont des vues de dessus et de face d'un flotteur utilisé pour réaliser la structure flottante de la figure 5,FIG. 5 is a diagrammatic view from above illustrating a second alternative embodiment of a floating structure for the assembly of FIG. 1; FIGS. 6 and 7 are top and front views of a float used for realize the floating structure of Figure 5,
- la figure 8 est une vue schématique de -dessus illustrant l'assemblage de plusieurs structures flottantes selon la figure 4,FIG. 8 is a schematic view of above illustrating the assembly of several floating structures according to FIG. 4;
- la figure 9 est une vue schématique en perspective détaillant l'assemblage aux angles de deux structures flottantes selon la figure 8,FIG. 9 is a schematic perspective view detailing the assembly at the corners of two floating structures according to FIG. 8,
- la figure 10 est une vue schématique en perspective illustrant deux flotteurs d'une structure flottante selon la figure 5 et une plaque de fixation à une structure flottante analogue, etFIG. 10 is a schematic perspective view illustrating two floats of a floating structure according to FIG. 5 and a plate for fastening to a similar floating structure, and
- la figure 11 est une schématique en perspective du dispositif d'accouplement de la figure 2 muni d'anneaux de liaison à des chaînes ou à des câbles. La figure 1 illustre un ensemble 1 comprenant une structure flottante 3 insubmersible, ou barge ou encore module, se positionnant automatiquement au minimum résistant selon la combinaison des vents et des courants marins, et sur laquelle plusieurs bateaux 5 sont amarrés. La liberté de positionnement de la structure flottante 3 réside en l'utilisation d'un dispositif d'accouplement 7 entre la structure flottante 3 et le fond marin sous la forme d'un pivot, également appelé « émerillon ».- Figure 11 is a schematic perspective of the coupling device of Figure 2 provided with connecting rings to chains or cables. Figure 1 illustrates an assembly 1 comprising a floating structure 3 unsinkable, or barge or module, automatically positioning at least resistant to the combination of wind and sea currents, and on which several boats 5 are moored. The freedom of positioning of the floating structure 3 resides in the use of a coupling device 7 between the floating structure 3 and the seabed in the form of a pivot, also called a "swivel".
L'ensemble 1 comprend donc la structure flottante 3 et le dispositif d'accouplement 7. La structure flottante 3 a une forme triangulaire et comprend ainsi trois côtés 9 et trois angles 11. Dans l'exemple représenté, la structure 3 a une forme de triangle équilatéral.The assembly 1 thus comprises the floating structure 3 and the coupling device 7. The floating structure 3 has a triangular shape and thus comprises three sides 9 and three angles 11. In the example shown, the structure 3 has a shape of equilateral triangle.
Comme illustré par la figure 2, le dispositif d'accouplement 7 comprend une base 13 reliée à la structure flottante, et un arbre 15 relié au fond marin.As illustrated in Figure 2, the coupling device 7 comprises a base 13 connected to the floating structure, and a shaft 15 connected to the seabed.
L'arbre 15 est reçu à rotation dans la base 13 pour pouvoir pivoter librement par rapport à la base 13 autour de son axe. L'arbre 15 est muni à son extrémité supérieure d'une rotule 17 d'appui sur la base 13. Une bague 19 est intercalée entre la rotule 17 et la base 13. De préférence, cette bague 19 est réalisée en un matériau limitant les frottements, par exemple en Delrin (marque déposée).The shaft 15 is rotatably received in the base 13 to pivot freely relative to the base 13 about its axis. The shaft 15 is provided at its upper end with a ball 17 bearing on the base 13. A ring 19 is interposed between the ball 17 and the base 13. Preferably, this ring 19 is made of a material limiting the friction, for example in Delrin (registered trademark).
Comme illustré par la figure 3, la base 13 a dans l'exemple représenté une forme triangulaire et présente dans chacun de ses angles 21 un point de liaison 23 à la structure flottante 3, par exemple sous la forme d'un ori- fice.As illustrated in FIG. 3, the base 13 has in the example shown a triangular shape and has in each of its angles 21 a connection point 23 to the floating structure 3, for example in the form of an orifice.
La liaison de la base 13 à la structure flottante 3 peut être par exemple assurée par des chaînes ou des câbles. Dans ce cas, chaque orifice 23 peut assurer la fixation d'un anneau ou manille 24 recevant une extrémité d'une chaîne ou d'un câble (fig. 11). De même, l'arbre 15 peut être relié au fond marin par l'intermédiaire d'une chaîne ou d'un câble reçu dans un anneau 25 (fig. 11) porté par l'extrémité inférieure de l'arbre 15.The connection of the base 13 to the floating structure 3 may for example be provided by chains or cables. In this case, each orifice 23 can secure a ring or shackle 24 receiving one end of a chain or cable (FIG 11). Similarly, the shaft 15 can be connected to the seabed by means of a chain or cable received in a ring 25 (FIG 11) carried by the lower end of the shaft 15.
Grâce au dispositif d'accouplement 7, la structure flottante 3 peut pi- voter librement par rapport au fond marin autour d'un axe A sensiblement vertical matérialisé sur la figure 1.Thanks to the coupling device 7, the floating structure 3 can move freely relative to the seabed around a substantially vertical axis A shown in FIG.
Du fait de la forme triangulaire de la structure flottante 3, elle va se positionner automatiquement afin de limiter les efforts qui s'exercent sur elle du fait du vent et des courants. Ainsi, la structure flottante 3 va pivoter auto- matiquement pour qu'un de ses angles 11 soit situé face à la résultante des forces exercées par les courants et les vents marins, cette résultante étant matérialisée par la flèche R sur la figure 1.Due to the triangular shape of the floating structure 3, it will position itself automatically to limit the forces exerted on it due to wind and currents. Thus, the floating structure 3 will pivot automatically so that one of its angles 11 is located opposite the resultant forces exerted by the currents and the marine winds, this resultant being materialized by the arrow R in FIG.
En outre, comme illustré par la figure 1 , la structure flottante 3 permet d'amarrer un nombre important de bateaux 5. Dans l'exemple représenté, deux bateaux 5 sont amarrés chacun le long d'un côté 9 respectif, tandis que deux autres bateaux 5 sont amarrés à la-traîne sur le dernier côté 9 (en bas sur la figure 1).In addition, as shown in FIG. 1, the floating structure 3 makes it possible to moor a large number of boats 5. In the example shown, two boats 5 are moored each along a respective side 9, while two others 5 boats are moored trolling on the last side 9 (bottom in Figure 1).
On entend ici par amarrage à la traîne, par opposition au terme amarrage le long d'un côté, un amarrage dans lequel le bateau 5" est amarré par sa proue au côté 9 correspondant, et ne s'étend pas sensiblement parallèlement à celui-ci.Trolling, as opposed to the term mooring along one side, is here understood to mean a mooring in which the boat 5 " is moored by its bow to the corresponding side 9, and does not extend substantially parallel to it. this.
Le nombre de bateaux 5 amarrés à la structure 3 peut également être plus réduit que celui de l'exemple de la figure 1. Ainsi, à titre d'exemple encore, un seul bateau 5 peut être amarré le long d'un côté et/ou un seul ba- teau peut être amarré à la traîne à un côté 9 plutôt que deux comme représenté sur la figure 1.The number of boats 5 moored to the structure 3 can also be smaller than that of the example of FIG. 1. Thus, by way of example only, a single boat 5 can be moored along one side and / or a single boat may be trolled to one side 9 rather than two as shown in Figure 1.
L'ensemble 1 permet donc d'augmenter le nombre de places de stationnement des bateaux ou embarcations.Set 1 thus makes it possible to increase the number of parking spaces for boats or boats.
En outre, le coût d'un tel ensemble 1 est réduit et il peut être installé à très faible coût par remplacement d'une bouée d'un corps mort existant. Il suffit alors d'ancrer l'ensemble 1 sur le même point que celui utilisé précédemment pour la bouée de corps mort.In addition, the cost of such a set 1 is reduced and it can be installed at very low cost by replacing a buoy of an existing dead body. he It is then sufficient to anchor the assembly 1 on the same point as that previously used for the dead body buoy.
En outre, du fait de sa forme triangulaire, la structure 3 est extrêmement stable avec une très bonne flottaison, un tangage très faible et une très bonne résistance aux vagues de sorte qu'une telle structure 3 peut être utilisée pour d'autres applications que l'amarrage de bateaux, comme cela sera exposé à la fin de la description.In addition, because of its triangular shape, the structure 3 is extremely stable with very good flotation, very low pitch and very good resistance to waves so that such a structure 3 can be used for other applications than the mooring of boats, as will be explained at the end of the description.
La liberté de pivotement de la structure 3 permet également d'accroître la stabilité de l'ensemble 1, puisque les efforts qui vont s'exercer sur la structure 3 seront minimisés pour les raisons exposées précédemment. Les risques d'endommagement des bateaux 5 amarrés sont donc réduits.The freedom of pivoting of the structure 3 also increases the stability of the assembly 1, since the forces that will be exerted on the structure 3 will be minimized for the reasons explained above. The risk of damage to boats 5 moored are reduced.
On observera en outre que le dispositif d'accouplement 7 permet de limiter les risques d'emmêlement des câbles ou chaînes le reliant à la struc- ture flottante 3.It will further be observed that the coupling device 7 makes it possible to limit the risks of entanglement of the cables or chains connecting it to the floating structure 3.
De plus, la zone d'évitement de l'ensemble 1 a une étendue réduite.In addition, the avoidance zone of the assembly 1 has a reduced extent.
La structure 3 peut être réalisée dans des matériaux divers et variés tels que, par exemple, les bois, les métaux, les matières plastiques et matières composites. Comme illustré par la figure 4, la structure flottante 3 peut être réalisée à base de blocs triangulaires 26. Dans l'exemple de la figure 4, la structure flottante 3 comprend donc quatre blocs 26.The structure 3 can be made of various and varied materials such as, for example, woods, metals, plastics and composite materials. As illustrated in FIG. 4, the floating structure 3 can be made on the basis of triangular blocks 26. In the example of FIG. 4, the floating structure 3 thus comprises four blocks 26.
La structure 3 peut également être réalisée d'autres manières. Ainsi, et comme illustré à titre d'exemple par la figure 5, la structure 3 peut com- prendre des flotteurs tubulaires 27 qui constituent les côtés 9 du triangle.The structure 3 can also be realized in other ways. Thus, and as illustrated by way of example in FIG. 5, the structure 3 may comprise tubular floats 27 which constitute the sides 9 of the triangle.
La structure d'un tel flotteur 27 est illustrée par la figure 6. Il s'agit d'un tube réalisé en aluminium, par exemple par roulage et soudage d'une feuille. Des cloisons 29 peuvent être disposées à l'intérieur du flotteur 27 pour constituer des caissons étanches 31. Les extrémités du flotteur 27 sont fermées par des platines 33 de fixation aux flotteurs 27 adjacents, par exemple par boutonnage. On observera que ces platines 33 sont inclinées d'environ 30° par rapport à l'axe longitudinal du flotteur 27.The structure of such a float 27 is illustrated in Figure 6. It is a tube made of aluminum, for example by rolling and welding a sheet. Partitions 29 may be arranged inside the float 27 to form watertight caissons 31. The ends of the float 27 are closed by plates 33 for attachment to the adjacent floats 27, by example by buttoning. It will be observed that these plates 33 are inclined by approximately 30 ° with respect to the longitudinal axis of the float 27.
De manière générale, quelle que soit la variante, des pare-battage ou bouées de défense 34 peuvent être prévus sur les côtés 9 et/ou les angles 11 (fig. 5) de Ia structure flottante 3.In general, whatever the variant, fenders or buoys 34 may be provided on the sides 9 and / or the angles 11 (FIG 5) of the floating structure 3.
En revenant à la figure 5, on peut constater que la structure flottante 3 est munie d'un plancher 35 triangulaire dont seule une partie a été représentée. Ce plancher peut être supporté par des entretoises 36 qui relient les flotteurs 27 entre-eux. De manière générale, la structure 3 pourra être munie d'un plancherReturning to FIG. 5, it can be seen that the floating structure 3 is provided with a triangular floor 35 of which only a portion has been shown. This floor can be supported by spacers 36 which connect the floats 27 to each other. In general, the structure 3 may be provided with a floor
35, qu'elle soit réalisée selon les figures 4 ou 5, ou selon toute autre variante. Ce plancher 35 pourra s'étendre sur l'essentiel de la structure flottante 3.35, whether it is carried out according to FIGS. 4 or 5, or according to any other variant. This floor 35 may extend over most of the floating structure 3.
Plusieurs structures flottantes 3 peuvent être assemblées entre elles par leurs côtés 9 ou leurs angles 11 pour former des zones flottantes de tailles et de formes géométriques variées.Several floating structures 3 can be assembled together by their sides 9 or their angles 11 to form floating zones of various sizes and geometric shapes.
Cela est illustré par exemple sur la figure & où les structures 3 sont des structures analogues à celles de la figure 4.This is illustrated for example in FIG. 4, where the structures 3 are structures similar to those of FIG.

Chacune de ces ailes 39 est alors destinée à être insérée entre les platines 33 des flotteurs 27 se rejoignant à un même angle 11 d'une structure 3. Le boulon- nage des platines 33 entre elles permet ainsi de fixer rigidement l'aile 39 à l'angle 11 correspondant de deux structures flottantes 3 adjacentes. D'autres modes de réalisation de structures flottantes 3 sont envisageables.The assembly between them of several floating structures 3 according to the variant embodiment of FIG. 5 can be ensured as illustrated by FIG. 10, thanks to fastening plates 37 which have two wings 39 each having a shape similar to that of FIG. a plate 33, the wings 39 being inclined relative to each other by an angle of about 60 °. Each of these wings 39 is then intended to be inserted between the plates 33 of the floats 27 joining at the same angle 11 of a structure 3. The bolting of the plates 33 between them thus makes it possible to rigidly fix the wing 39 to the corresponding angle 11 of two adjacent floating structures 3. Other embodiments of floating structures 3 are conceivable.
