Les figures 1 A à 1 E illustrent un premier mode de réalisation d'un dispositif de transfert d'un produit fluide, notamment du gaz naturel liquéfié, entre un navire de transport du produit désigné par la référence 1 et une installation de réception de ce produit du navire ou de fourniture de ce produit au navire. Dans l'exemple représenté, l'installation est formée par une barge indiquée en 2. Le système de transfert portant la référence générale 3 comporte essentiellement un portique 4 monté sur la barge 2 et un dispositif tubulaire de transfert du fluide 6 qui est supporté par le portique 4 et est destiné à interconnecter le dispositif de manifold 8 du navire à une tuyauterie fixe 7 montée sur le portique 4 et connectée à l'espace de stockage (non représenté) de la barge.FIGS. 1 A to 1 E illustrate a first embodiment of a device for transferring a fluid product, in particular liquefied natural gas, between a ship for transporting the product designated by the reference 1 and an installation for receiving this product of the ship or supply of that product to the ship. In the example shown, the installation is formed by a barge indicated at 2. The transfer system bearing the general reference 3 essentially comprises a gantry 4 mounted on the barge 2 and a tubular fluid transfer device 6 which is supported by the gantry 4 and is intended to interconnect the manifold device 8 of the ship to a fixed pipe 7 mounted on the gantry 4 and connected to the storage space (not shown) of the barge.
Le dispositif de transfert comporte trois paires de bras articulés 9. Chaque paire de bras 9 est formée par un bras interne 10 connecté à son extrémité supérieure en haut du portique 4 à une ligne 7' de la tuyauterie fixe, et un bras extérieur 11 qui est relié à une extrémité par deux joints rotatifs à axe perpendiculaire 12 au bras interne 10 et porte à son autre extrémité un dispositif de raccord permettant la connexion au dispositif manifold 8 du navire pour un transfert de fluide entre le navire et la barge. L'extrémité supérieure de chaque bras interne 10 est connectée à sa ligne de tuyauterie 7' par deux joints rotatifs 18 dont les axes de rotation sont perpendiculaires l'un à l'autre.The transfer device comprises three pairs of articulated arms 9. Each pair of arms 9 is formed by an internal arm 10 connected at its upper end at the top of the gantry 4 to a line 7 'of the fixed piping, and an external arm 11 which is connected at one end by two rotary joints with a perpendicular axis 12 to the internal arm 10 and carries at its other end a connection device allowing the connection to the manifold device 8 of the ship for a transfer of fluid between the ship and the barge. The upper end of each internal arm 10 is connected to its pipe line 7 ′ by two rotary joints 18 whose axes of rotation are perpendicular to each other.
Le dispositif de connexion 14 est relié au bras externe 11 par deux joints tournants à axes perpendiculaires 20 et comporte essentiellement un connecteur 22 destiné à être monté sur un connecteur 24 du manifold correspondant du dispositif manifold 8 du navire et une tige de centrage 26 appelée pinoche destinée à s'engager lors de l'établissement d'une connexion dans une trompette de centrage 28 qui est associée au connecteur 24 du dispositif manifold 8. Comme on le voit sur les figures, les axes du connecteur 22 et de la pinoche 26 sont parallèles et latéralement décalés l'un de l'autre dans le plan de la figure 1 A.The connection device 14 is connected to the external arm 11 by two rotating joints with perpendicular axes 20 and essentially comprises a connector 22 intended to be mounted on a connector 24 of the corresponding manifold of the ship's manifold device 8 and a centering rod 26 called a pin intended to engage when establishing a connection in a centering trumpet 28 which is associated with the connector 24 of the manifold device 8. As is seen in the figures, the axes of the connector 22 and the pin 26 are parallel and laterally offset from each other in the plane of Figure 1 A.
Le dispositif de manœuvre du système de transfert selon l'invention comporte essentiellement un câble de manœuvre 30 qui est fixé à une extrémité au bras externe 11 près de l'extrémité libre de celui-ci et dont l'autre extrémité est enroulée sur un treuil 32 disposé en haut du portique 4. Le dispositif comporte en outre un câble 34 dont une extrémité peut être fixée au bout de la pinoche 26 tandis que son autre extrémité peut être enroulée sur un treuil 36 monté sur le manifold auquel le bras externe 11 doit être connecté à travers la trompette 28. En se référant aux figures 1 A à 1 E on décrira ci- après le processus de la connexion et de déconnexion du dispositif de transfert 3 selon l'invention au dispositif manifold 8 d'un navire.The operating device of the transfer system according to the invention essentially comprises an operating cable 30 which is fixed at one end to the external arm 11 near the free end thereof and the other end of which is wound on a winch 32 disposed at the top of the gantry 4. The device further comprises a cable 34, one end of which can be fixed to the end of the pin 26 while its other end can be wound on a winch 36 mounted on the manifold to which the external arm 11 must be connected through the trumpet 28. With reference to FIGS. 1 A to 1 E, the process of connecting and disconnecting the transfer device 3 according to the invention to the manifold device 8 of a ship will be described below.
La figure 1 B montre le dipositif de transfert dans sa position de stockage sur la barge 2. Dans cette position le bras externe 11 repose sur un socle de support 40 disposé sur un plan incliné.41. Le bras est incliné de façon que son dispositif de connexion 14 se trouve en-dessous du joint 12 d'articulation des deux bras 11 et 10. Le dispositif 14 est orienté de façon que les axes du connecteur 24 et de sa pinoche 26 soient orientés verticalement vers le haut.Figure 1B shows the transfer device in its storage position on the barge 2. In this position the outer arm 11 rests on a support base 40 disposed on an inclined plane. 41. The arm is inclined so that its connection device 14 is located below the joint 12 of articulation of the two arms 11 and 10. The device 14 is oriented so that the axes of the connector 24 and its pin 26 are oriented vertically upwards.
Pour effectuer le transfert de gaz naturel liquéfié entre un navire de transport 1 et la barge 2 , on amarre le navire à la barge avec interposition de défenses d'accostage 42 entre les coques. Puis, comme l'illustre la figure 1 D, on fixe à la pointe de la pinoche 26 le câble 34 que l'on fait passer à travers la trompette 28 du dispositif manifold du navire pour que l'extrémité libre puisse être enroulée autour du treuil 36. On soulève le bras interne 11 en enroulant le câble de manœuvre 30 sur le treuil 32 pour décoller le dispositif de transfert du socle de support . On poursuit le mouvement de soulèvement du dispositif de transfert en enroulant le câble 34 sur le treuil 36. L'engagement de la pinoche 26 dans sa trompette 28 assure le raccordement du connecteur 22 du dispositif de transfert au connecteur 24 du dispositif manifold du navire. La position de connexion est montrée sur la figure 1 A. Pour déconnecter le dispositif de transfert suspendu sous le portique 4 monté sur la barge 2, du dispositif manifold 8 du navire 1, on assure le déroulement du câble 34 de son treuil 36, ce qui permet le désengagement de la pinoche 24 de la trompette 28, jusqu'à ce que le câble 34 soit déroulé de son treuil et tombe librement, comme on le voit sur la. figure 1 E, le bras étant alors maintenu par le câble 30. Puis en continuant à relâcher le câble 30, le dispositif de transfert peut retrouver sa position de stockage montrée sur la figure 1 B.To carry out the transfer of liquefied natural gas between a transport ship 1 and the barge 2, the ship is moored to the barge with interposition of docking defenses 42 between the hulls. Then, as illustrated in FIG. 1 D, the point of the pinoche 26 is fixed to the cable 34 which is passed through the trumpet 28 of the ship's manifold device so that the free end can be wound around the winch 36. The internal arm 11 is raised by winding the operating cable 30 on the winch 32 to remove the transfer device from the support base. The lifting movement of the transfer device is continued by winding the cable 34 on the winch 36. The engagement of the pin 26 in its trumpet 28 ensures the connection of the connector 22 of the transfer device to the connector 24 of the ship's manifold device. The connection position is shown in FIG. 1 A. To disconnect the transfer device suspended under the gantry 4 mounted on the barge 2, from the manifold device 8 of the ship 1, the cable 34 of its winch 36 is ensured, this which allows the disengagement of the pin 24 of the trumpet 28, until the cable 34 is unwound from its winch and falls freely, as seen on the. Figure 1 E, the arm then being held by the cable 30. Then by continuing to release the cable 30, the transfer device can return to its storage position shown in Figure 1 B.
Les figures 2 A à 2 C illustrent un deuxième mode de réalisation du dispositif de transfert selon l'invention. Dans ce cas le dispositif de transfert comporte essentiellement trois flexibles cryogéniques 42 dont une extrémité est suspendue sous un portique 44 monté sur une plate-forme 45 reposant sur des pieux 46 enfoncés dans le fond marin. Cette extrémité de chaque flexible est connectée à demeure à une ligne de tuyauterie fixe non représentée de l'installation de réception et de fourniture de gaz naturel liquéfié. L'autre extrémité 47 du flexible est suspendue sous un portique 49 monté sur un plate-forme 50 reposant sur des pieux 51 enfoncés dans le fond marin.Figures 2 A to 2 C illustrate a second embodiment of the transfer device according to the invention. In this case, the transfer device essentially comprises three cryogenic hoses 42, one end of which is suspended under a gantry 44 mounted on a platform 45 resting on piles 46 driven into the seabed. This end of each hose is permanently connected to a fixed line of piping not shown in the installation for receiving and supplying liquefied natural gas. The other end 47 of the hose is suspended under a gantry 49 mounted on a platform 50 resting on piles 51 driven into the seabed.
L'extrémité libre 47 du flexible porte un dispositif de connexion correspondant au dispositif 14 du premier mode de réalisation et porte donc la même référence. Ce dispositif de connexion est articulée à l'extrémité d'un bras 53. Le bras 53 porte à son extrémité libre un contrepoids 55. Le bras est suspendu sous une structure de support 57 montée en haut du portique 49, par l'intermédiaire d'un câble 59 dont une extrémité est enroulée autour d'un treuil 60 disposé sur la structure de support 57 tandis que l'autre extrémité de ce cable est fixée en 61 au bras 53 à un endroit entre le contrepoids 55 et le milieu du bras. L'extrémité avant du bras est suspendue par un câble 63 sous la structure de support 57 en étant enroulé par son extrémité libre sur un treuil 64 qui fait partie de la structure de support 57. Comme on le voit sur la figure 2 B, dans sa position de stockage, le câble 63 est enroulé sur son treuil 64 si bien que l'extrémité 47 de chaque flexible 42, qui porte un dispositif de connexion 14, se trouve suspendu en haut sous la structure de support 57 du portique 42. Pour établir une connexion entre le dispositif manifold 8 du navire 1, on déroule le câble 63 de son treuil 64, et on place le câble 34 interconnectant le treuil 36 du dispositif manifold et la pinoche 26 du dispositif de connexion 14 et on établit la connexion de la manière déjà décrite pour le premier mode de réalisation selon les figures 1 A à 1 E.The free end 47 of the hose carries a connection device corresponding to device 14 of the first embodiment and therefore bears the same reference. This connection device is articulated at the end of an arm 53. The arm 53 carries at its free end a counterweight 55. The arm is suspended under a support structure 57 mounted at the top of the gantry 49, via '' a cable 59, one end of which is wound around a winch 60 disposed on the support structure 57 while the other end of this cable is fixed at 61 to the arm 53 at a location between the counterweight 55 and the middle of the arm . The front end of the arm is suspended by a cable 63 under the support structure 57 while being wound by its free end on a winch 64 which is part of the support structure 57. As can be seen in FIG. 2B, in in its storage position, the cable 63 is wound on its winch 64 so that the end 47 of each hose 42, which carries a connection device 14, is suspended above under the support structure 57 of the gantry 42. For establish a connection between the manifold device 8 of the ship 1, the cable 63 is unwound from its winch 64, and the cable 34 is placed interconnecting the winch 36 of the manifold device and the pin 26 of the connection device 14 and the connection is established. the manner already described for the first embodiment according to FIGS. 1 A to 1 E.
On constate que la suspension du bras 53 par le câble 59 et le contrepoids 55 à l'extrémité du bras assure un état d'équilibre stable et permet en outre une réduction des efforts de la manœuvre lors de la connexion au manifold du navire et des efforts sur ceux-ci, y compris pendant le transfert.It can be seen that the suspension of the arm 53 by the cable 59 and the counterweight 55 at the end of the arm ensures a stable state of equilibrium and also allows a reduction of the maneuver forces during the connection to the manifold of the ship and of the efforts on these, including during the transfer.
Les figures 3 A et 3 B montrent une autre version du mode de réalisation du dispositif de transfert selon les figure 2 A à 2 C. Cette version de réalisation se distingue par la configuration du dispositif de connexion au manifold du navire. Comme on le voit très clairement sur la figure 3 B, le dispositif de connexion monté à l'extrémité de chaque flexible et qui porte maintenant la référence 66 est configuré de façon à ce que les axes du connecteur et de la pinoche notés respectivement 67 et 68 sont orientés verticalement de façon à s'engager d'en haut sur le connecteur 70, orienté vers le haut, et la pinoche 71 du dispositif manifold 8 du navire. Lors de la connexion, le dispositif de connexion 60 prend appui sur la plate-forme de manifold 73 à l'aide d'un pied 74 solidaire du dispositif de connexion 66 et destiné à venir en appui sur la plate-forme 70.Figures 3 A and 3 B show another version of the embodiment of the transfer device according to Figure 2 A to 2 C. This embodiment is distinguished by the configuration of the device for connection to the ship's manifold. As we can see very clearly in FIG. 3B, the connection device mounted at the end of each hose and which now bears the reference 66 is configured so that the axes of the connector and of the pin marked respectively 67 and 68 are oriented vertically so to engage from above on the connector 70, oriented upwards, and the pin 71 of the manifold device 8 of the ship. During the connection, the connection device 60 bears on the manifold platform 73 by means of a foot 74 secured to the connection device 66 and intended to come to bear on the platform 70.
Bien entendu de nombreuses modifications peuvent être apportées au système tel que décrit et représenté sur les figures. Ainsi on pourrait implanter les portiques 44 et 49 avec les flexibles cryogéniques, selon les figures 2A à 2C et 3A et 3B sur tout autre support notamment flottant, tel qu'une unité flottante de stockages et/ou de production du gaz naturel liquéfié ou sur une barge telle que représentée sur les figures 1A à 1E. Il est également possible de monter le dispositif de transfert selon les figures 1A à 1E sur tout autre support notamment fixe, tel que les plateformes selon les figures 2A et 2B.Of course, numerous modifications can be made to the system as described and shown in the figures. Thus, the gantries 44 and 49 could be installed with the cryogenic hoses, according to FIGS. 2A to 2C and 3A and 3B on any other support, in particular floating, such as a floating unit for storing and / or producing liquefied natural gas or on a barge as shown in Figures 1A to 1E. It is also possible to mount the transfer device according to FIGS. 1A to 1E on any other particularly fixed support, such as the platforms according to FIGS. 2A and 2B.
Il est à noter qu'une caractéristique essentielle de l'invention réside dans le fait que pendant les phases sensibles de connexion/déconnexion du dispositif de transfert déformable un câble unique exécute les fonctions de supportage/hissage de l'extrémité mobile de ce système déformable et de guidage, notamment latéralement. Ce câble unique est arrangé selon l'axe des mouvements principaux du navire (pilonne ent) . It should be noted that an essential characteristic of the invention resides in the fact that during the sensitive phases of connection / disconnection of the deformable transfer device, a single cable performs the functions of supporting / hauling the mobile end of this deformable system. and guide, especially laterally. This single cable is arranged along the axis of the main movements of the ship (pounder).
