Abstract

The mooring consists of a tube (6) connected to the vessel hinges (12) onto the frame (8). The opposite end of the mooring arm is connected to a cylindrical part (2) anchored by chains (3). The ends of the arm are in contact with the post through tyred rollers (11). The rollers are mounted in pairs through a common axis joined to a central radial bracket. The outside of the post is surrounded by a belt (23) on which the rollers may run. The belt is located in side flanges.

Description

Translated fromFrench

La présente invention se rapporte à un mode particulier de réalisation de l'invention telle que décrite dans le brevet principal. The present invention relates to a particular embodiment of the invention as described in the main patent.

Le dispositif décrit dans le brevet principal pour amarrer une installation flottante à une installation marine assujettie à un point fixe du fond de l'eau et présentant sur une portion au moins de sa longueur une surface ex extérieure sensiblement cylindrique d'axe vertical, comporte un bras de liaison rigide articulé sur l'installation flottante autour d'un axe sensiblement horizontal. Ce bras de liaison porte des moyens de roulement maintenus en contact avec des chemins de roulement solidaires de l'installation marine, par des moyens de solidarisation qui autorisent la rotation du bras autour de l'axe vertical par déplacement des moyens de roulement sur leurs chemins de roulement. The device described in the main patent for mooring a floating installation to a marine installation subject to a fixed point of the bottom of the water and having, over at least a portion of its length, a substantially cylindrical external external surface with vertical axis, comprises a rigid link arm articulated on the floating installation around a substantially horizontal axis. This link arm carries rolling means maintained in contact with raceways integral with the marine installation, by securing means which allow the rotation of the arm around the vertical axis by displacement of the rolling means on their paths. of rolling.

La présente invention propose des perfectionnements à ce disPositif qui permettent d'obtenir un meilleur fonctionnement et qui sont illustrés par les figures annexées parmi lesquelles - la figure 1 est une vue de dessus du dispositif et - la figure 2 est une coupe selon la ligne II de la figure
1.
The present invention proposes improvements to this device which make it possible to obtain better operation and which are illustrated by the appended figures among which - FIG. 1 is a top view of the device and - FIG. 2 is a section along line II of the figure
1.

Sur ces figures, on a utilisé les mêmes références que celles employées dans le brevet principal pour désigner les mêmes éléments. In these figures, the same references have been used as those used in the main patent to designate the same elements.

Comme indiqué dans le brevet prjncipal, l'installation flottante 1, telle qu'un navire, est amarrée à poste fixe autour d'une installation marine 2 telle qu'une bouée flottante cylindrique, assujettie au fond de l'eau par des lignes d'ancrage 3, 3a, 3b ... La liaison entre le navire 1 et la bouée 2 est assurée par un bras rigide 6, articulé en 9 sur le navire. Ce bras porte des ensembles de roues sensiblement coplanaires 17, lia, llb ... Un seul de ces ensembles est visible sur la figure 1 mais plusieurs ensembles identiques sont situés à des niveaux différents de la bouée 2. Ces roues constituent des moyens de roulement permettant la rotation du bras 6 autour de l'axe vertical de la bouée. As indicated in the main patent, the floating installation 1, such as a ship, is moored at a fixed post around a marine installation 2 such as a cylindrical floating buoy, secured to the bottom of the water by lines d anchoring 3, 3a, 3b ... The connection between the ship 1 and the buoy 2 is provided by a rigid arm 6, articulated at 9 on the ship. This arm carries substantially coplanar wheel assemblies 17, lia, llb ... Only one of these assemblies is visible in FIG. 1 but several identical assemblies are located at different levels of the buoy 2. These wheels constitute rolling means allowing the rotation of the arm 6 around the vertical axis of the buoy.

Des ceintures1 sangles ou courroies telles que 23 assurent la liaison du bras 6 et de la bouée 2. Chaque ceinture est en contact avec la bouée 2 et une roue 10 solidaire du bras 6, des vérins hydrauliques 31 permettant de tendre les courroies par déplacement de la roue 10. Belts1 straps or belts such as 23 ensure the connection of the arm 6 and the buoy 2. Each belt is in contact with the buoy 2 and a wheel 10 secured to the arm 6, hydraulic cylinders 31 making it possible to tension the belts by displacement of wheel 10.

Selon la présente invention, on empêche les glissements relatifs des ceintures 23 et de la bouée 2 dans la direction parallèle à l'axe de cette dernière en plaçant les ceintures dans des gorges portées par la bouée 2. Ces gorges sont, par exemple, délimitées par la paroi verticale de la bouée 2 et des flasques 61 solidaires de la bouée. According to the present invention, relative sliding of the belts 23 and of the buoy 2 is prevented in the direction parallel to the axis of the latter by placing the belts in grooves carried by the buoy 2. These grooves are, for example, delimited by the vertical wall of the buoy 2 and the flanges 61 secured to the buoy.

De plus, les efforts tranchants au niveau de la liaison bras-bouée sont transmis par l'intermédiaire des ceintures. En effet, comme on peut le voir sur la figure 2, pour chaque ceinture, la surface extérieure 62 opposée à celle qui est en contact avec la paroi cylindrique de la bouée, a un profil concave qui constitue une bande de roulement sur laquelle prennent appui les roues 11, lia ... équipées de penumatiques et qui ont une surface extérieure convexe sensiblement complémentaire de la surface extérieure 62 des ceintures. In addition, the shear forces at the arm-buoy link are transmitted through the belts. Indeed, as can be seen in Figure 2, for each belt, the outer surface 62 opposite to that which is in contact with the cylindrical wall of the buoy, has a concave profile which constitutes a tread on which are supported the wheels 11, lia ... equipped with penumatics and which have a convex external surface substantially complementary to the external surface 62 of the belts.

Pour assurer un roulement correct des roues sur leurs chemins de roulement, chaque ensemble de roues est porté par un support 64 articulé autour d'un axe 63 disposé radialement par rapport à la bouée 2 dans un plan sensiblement perpendiculaire à l'axe vertical de la bouée. To ensure correct rolling of the wheels on their raceways, each set of wheels is carried by a support 64 articulated around an axis 63 disposed radially relative to the buoy 2 in a plane substantially perpendicular to the vertical axis of the buoy.
