Le procédé selon l'invention est caractérisé par les étapes suivantes :
- a) on assemble entre eux à quai au moins deux premiers cylindres périphériques,
- b) on assemble le cylindre central à ces deux cylindres périphériques,
- c) on met à l'eau l'ensemble constitué par ledit cylindre central et au moins lesdits premiers cylindres périphériques,

Dans le cas où les cylindres périphériques sont assemblés au cylindre principal suivant les génératrices et où les cylindres périphériques se prolongent au delà de l'une des extrémité du cylindre principal, le procédé selon l'invention peut comporter l'assemblage d'un cylindre annexe auxdits deux cylindres périphériques.In the case where the peripheral cylinders are assembled to the main cylinder along the generators and where the peripheral cylinders extend beyond one of the ends of the main cylinder, the method according to the invention may include the assembly of an annex cylinder to said two peripheral cylinders.

La référence 1 désigne la plateforme dans son ensemble. Celle-ci comprend un cylindre métallique principal de flottaison A,, adapté à occuper en service une position verticale, le bas de ce cylindre étant situé au-dessous du niveau 2 de l'eau. La partie supérieure du cylindre A, émerge en service au-dessus du niveau de l'eau et supporte un pont 3.The reference 1 designates the platform as a whole. This comprises a main metallic flotation cylinder A ,, adapted to occupy a vertical position in service, the bottom of this cylinder being located below
Le cylindre principal de flottaison A, est entouré d'au moins une couronne de cylindres métalliques périphériques A2, A3... qui descendent au-dessous du cylindre A,. Cette disposition dégage sous le cylindre de flottaison A, un espace libre E limité par la couronne de cylindre périphérique A2, A3...The main flotation cylinder A, is surrounded by at least one ring of peripheral metal cylinders A 2 , A 3 ... which descend below the cylinder A ,.

La figure 2 représente un cylindre périphérique A4 comportant deux éléments 5 et 6 qui sont placés sur des berceaux 7 et assemblés entre eux, notamment, par soudage.FIG. 2 represents a peripheral cylinder A 4 comprising two
La référence 8 désigne un quai et la référence 9 un bassin.The
La figure 3 représente deux premiers cylindres périphériques A4 et A5 qui sont assemblés entre eux et posés sur un berceau 10. Ce berceau est posé éventuellement sur des éléments 11 de glissement ou de roulement qui faciliteront, le moment venu, la mise à l'eau d'une partie du système.FIG. 3 represents two first peripheral cylinders A 4 and A5 which are assembled together and placed on a
Le cylindre principal A1 est assemblé à ces deux premiers cylindres A4 et As.The main cylinder A 1 is assembled with these first two cylinders A 4 and A s .
Cette opération peut être effectuée en plaçant directement le cylindre A sur les cylindres périphériques A1 et A4 ou en assemblant progressivement les différents éléments B1, B2, B3... Bn qui constituent ce cylindre principal A1, ainsi que le montrent les figures 5 et 6.This operation can be carried out by placing the cylinder A directly on the peripheral cylinders A 1 and A 4 or by gradually assembling the various elements B 1 , B 2 , B 3 ... B n which constitute this main cylinder A 1 , as well as this is shown in Figures 5 and 6.
Les figures 4A, 4B et 4C montrent un mode avantageux d'assemblage du cylindre principal A,.FIGS. 4A, 4B and 4C show an advantageous method of assembling the main cylinder A,.
Certains des éléments B3 et B4 sont assemblés horizontalement (Fig. 4B) l'élément B3 comportant un fond 12, puis, si nécessaire, des équipements 13 sont mis en place dans les éléments B3 et B4.Some of the elements B 3 and B 4 are assembled horizontally (FIG. 4B) the element B 3 comprising a
Le sous-ensemble ainsi constitué B3, B4 et 13 est transporté par une grue 14 et est assemblé aux premiers cylindres périphériques A4 et As et à la partie déjà en place du cylindre principal B1, B2.The subassembly thus formed B 3 , B 4 and 13 is transported by a
Les différents cylindres peuvent être assemblés entre eux grâce à des organes de liaison 15 éventuellement soudables.The different cylinders can be assembled together by means of connecting
Selon un mode particulier de réalisation, la couronne de cylindres périphériques A2, A3... est fixée de manière rigide par soudure au cylindre principal.According to a particular embodiment, the ring of peripheral cylinders A 2 , A 3 ... is rigidly fixed by welding to the main cylinder.
Afin de faciliter la construction d'un tel système modulaire, il sera avantageux d'incorporer à la virole 1 de chaque cylindre, A1, A2, A3... un organe de liaison 15 lors de la fabrication de cette virole, l'assemblage de deux cylindres voisins étant alors réalisé par soudure entre les organes de liaison 15 dont sont équipés ces cylindres.In order to facilitate the construction of such a modular system, it will be advantageous to incorporate into the shell 1 of each cylinder, A 1 , A 2 , A 3 ... a connecting
La figure 6 montre l'ensemble constitué des deux premiers cylindres périphériques A4 et As et du cylindre principal A1.FIG. 6 shows the assembly made up of the first two peripheral cylinders A 4 and A s and of the main cylinder A 1 .
Cet ensemble peut être équipé d'un organe de renfort, tel un cylindre annexe 16, servant à rigidifier la structure finale (Fig.7).This assembly can be fitted with a reinforcing member, such as an
Des rampes 17 sont mises en place, elles relient le quai 8 à une barge 18 (Fig. 7 et 8).
Le berceau 10 supportant l'ensemble A1, A4, As est déplacé, éventuellement par rippage, pour être placé sur la barge 18.The
Des cylindres périphériques A3 et A6 peuvent être assemblés à l'ensemble constitué des deux premiers cylindres périphériques A4 et As et du cylindre principal A1, de manière à assurer une meilleure stabilité dans l'eau au nouvel ensemble ainsi constitué (Fig. 10)Peripheral cylinders A 3 and A 6 can be assembled to the assembly consisting of the first two peripheral cylinders A 4 and A s and of the main cylinder A 1 , so as to ensure better stability in water for the new assembly thus constituted ( Fig. 10)
Ces cylindres A3 et A6 peuvent être mis en place, soit lorsque l'ensemble est encore à quai, soit lorsque l'ensemble est placé sur la barge 18 (Fig. 9).These cylinders A 3 and A 6 can be put in place, either when the assembly is still docked, or when the assembly is placed on the barge 18 (FIG. 9).
Dans ce dernier cas, la barge pourra être tournée de 180° pour permettre la mise en place de ces cylindres périphériques.In the latter case, the barge can be turned 180 ° to allow the establishment of these peripheral cylinders.
La barge 18 est ensuite basculée ou immergée éventuellement par lestage ou balastage afin de permettre la mise à l'eau du nouvel ensemble A1, A3, A4, A5, A6 (Fig. 11). Sur la figure 11, le basculement de la barge se fait latéralement. Il est bien évident que ledit basculement pourra être effectué dans une autre direction, notamment longitudinalement.The
L'assemblage des cylindres périphériques A2, A7... se poursuit alors que l'ensemble est dans l'eau.The assembly of the peripheral cylinders A 2 , A 7 ... continues while the assembly is in the water.
On ne sortira pas du cadre de la présente invention en effectuant la mise à l'eau d'une partie du système sans utiliser de barge, comme cela se fait d'ailleurs pour le lancement des navires.It will not depart from the scope of the present invention to effect the launching of part of the system without using a barge, as is done for the launching of ships.
La mise en place de ce système sur le site choisi pourra avantageusement être réalisé en remorquant séparément le groupe de cylindres (Fig. 2) et le pont mis en flottaison, par exemple grâce à des barges. Par ballastage de certains cylindres, le groupe des cylindres est basculé en position verticale et le raccordement sur le site est alors effectué entre le pont demeurant horizontal et l'ensemble de cylindres en position verticale.The installation of this system on the chosen site can advantageously be carried out by towing the group of cylinders (Fig. 2) and the bridge floated separately, for example by barges. By ballasting certain cylinders, the group of cylinders is tilted to the vertical position and the connection to the site is then made between the bridge remaining horizontal and the cylinder assembly in the vertical position.
Ce raccordement peut se faire par ballastage de certains cylindres par la mise du pont à la verticale du cylindre principal, puis par déballastage de ces cylindres.This connection can be made by ballasting certain cylinders by placing the bridge vertically on the main cylinder, then by deballasting these cylinders.
