Des systèmes de transfert de ce type, qui sont déjà connus, présentent l'inconvénient majeur d'avoir une structure très complexe sans pour autant pouvoir fonctionner dans des conditions d'environnement sévères impliquant un mouvement relatif important entre le navire de transport et le poste de stockage, notamment lorsque celui-ci est un navire de stockage.Transfer systems of this type, which are already known, have the major disadvantage of having a very complex structure without being able to operate in severe environmental conditions involving a significant relative movement between the transport vessel and the post storage, especially when it is a storage vessel.

Le document WO 01/04041 décrit un tel système. Il est basé sur une chaîne de tuyaux articulés s'étendant entre le poste de stockage et le navire.The document WO 01/04041 describes such a system. It is based on a chain of articulated pipes extending between the storage station and the ship.

La présente invention a pour but de pallier ces inconvénients et de proposer un système de transfert d'une structure relativement simple et adaptable même aux conditions d'environnement difficiles, tout en permettant le transfert de gaz naturel liquéfié.The present invention aims to overcome these disadvantages and to provide a transfer system of a relatively simple structure and adaptable even in difficult environmental conditions, while allowing the transfer of liquefied natural gas.

Pour atteindre ce but, le système de transfert selon l'invention est caractérisé en ce qu'il comporte une conduite de transfert souple suspendue librement entre ses extrémités dans sa position de transfert connectée au dispositif manifold du navire de transport et en ce qu'à chacune de ses deux extrémités est prévu un joint tournant à axe vertical de façon à éviter les sollicitations en torsion et gauchissement de la conduite.To achieve this purpose, the transfer system according to the invention is characterized in that it comprises a flexible transfer line freely suspended between its ends in its transfer position connected to the manifold device of the transport vessel and in that each of its two ends is provided with a rotating joint with a vertical axis so as to avoid stresses in torsion and warping of the pipe.

Selon une autre caractéristique de l'invention, la conduite souple est formée par un flexible tel qu'un flexible cryogénique, adapté pour le transfert d'un gaz naturel liquéfié.According to another characteristic of the invention, the flexible pipe is formed by a hose such as a cryogenic flexible, adapted for the transfer of a liquefied natural gas.

Sur les figures les références 1, 2 et 3 désignent respectivement un navire de transport d'un produit tel que du gaz naturel liquéfié, un navire de stockage de ce produit et un système de transfert de ce produit entre les deux navires 1 et 2, conformément à l'invention. Le numéro 4 indique le niveau d'eau.In the figures, references 1, 2 and 3 respectively denote a vessel carrying a product such as liquefied natural gas, a storage vessel for this product and a system for transferring this product between the two vessels 1 and 2, according to the invention. Number 4 indicates the water level.

Le système de transfert selon l'invention comporte, dans l'exemple représenté, essentiellement deux conduites souples de transfert de fluide 5 qui, à l'état de repos du système, sont enroulées sur une roue 6 montée en haut d'une structure de support 7 en forme d'une tour montée à une extrémité du navire de stockage 2. A l'état de travail, c'est-à-dire dans sa position de transfert d'un produit entre les deux navires, chaque conduite formé avantageusement par un flexible cryogénique est déroulée de sa roue de stockage 6 et connectée à un dispositif manifold 9 supporté par une structure de support commune 10 disposée à l'avant du navire de transport 1. Ainsi chaque flexible 5 s'étend librement en chaînette entre ses extrémités. On constate encore que le navire de transport 1 est amarré au navire de stockage à l'aide de tout moyen approprié tel que par exemple une aussière 10. Dans l'exemple représenté, le navire de stockage 2 est amarré et relié au fond en 11.The transfer system according to the invention comprises, in the example shown, essentially two flexible fluid transfer lines 5 which, in the state of rest of the system, are wound on a wheel 6 mounted on top of a structure of support 7 in the form of a tower mounted at one end of the storage vessel 2. In the working state, that is to say in its position of transfer of a product between the two vessels, each pipe formed advantageously by a cryogenic hose is unwound from its storage wheel 6 and connected to a manifold device 9 supported by a common support structure 10 disposed at the front of the transport vessel 1. Thus, each hose 5 freely extends in a chain between its ends. It can also be seen that the transport vessel 1 is moored to the storage vessel by any suitable means such as, for example, a hawser 10. In the example shown, the storage vessel 2 is moored and connected to the bottom 11 .

Comme le montre la figure 4, les deux roues de stockage 6 d'un flexible 5 sont montées pivotantes sur leur tour de support, autour d'un axe vertical de façon à permettre un mouvement relatif entre le navire de transport 1 et le navire de stockage selon un angle α sans que les flexibles soient sollicités en torsion. Ce pivotement est assuré par des moyens constituant ainsi un axe tournant à axe vertical indiqué en 8. Les deux tours de support 7 peuvent avantageusement être disposées symétriquement par rapport à l'axe longitudinal X-X du navire de stockage. L'axe longitudinal du navire de transport est noté Y-Y.As shown in figure 4 , the two storage wheels 6 of a hose 5 are pivotally mounted on their support tower, about a vertical axis so as to allow relative movement between the transport vessel 1 and the storage vessel at an angle α without that the hoses are stressed in torsion. This pivoting is ensured by means thus constituting a rotating axis with a vertical axis indicated at 8. The two support towers 7 may advantageously be arranged symmetrically with respect to the longitudinal axis XX of the storage vessel. The longitudinal axis of the transport ship is noted YY.

L'extrémité libre désignée par la référence générale 13 d'un flexible cryogénique 5 est formée par un embout qui porte un connecteur rapide 14, un dispositif de déconnexion d'urgence 15 disposé à une certaine distance axiale du connecteur 14. L'embout 13 porte en outre une tige de centrage appelée pinoche 17 qui est latéralement décalée de l'axe de l'embout mais s'étend parallèlement à celui-ci sensiblement dans le plan vertical formé par la caténaire du flexible.The free end designated by the general reference 13 of a cryogenic hose 5 is formed by a tip which carries a quick connector 14, an emergency disconnection device 15 disposed at a certain axial distance from the connector 14. The tip 13 further carries a center pin pinoche 17 which is laterally offset from the axis of the tip but extends parallel thereto substantially in the vertical plane formed by the catenary hose.

Pour chaque câble 5 est prévu sur l'avant du navire de transport 1 un dispositif de manifold 9 monté sur la structure de support 10 d'une certaine hauteur, qui porte en haut deux passerelles 22 et 23. Les deux passerelles sont décalées dans l'axe du navire, en se chevauchant légèrement, la passerelle avant 23 étant disposée au-dessus de la passerelle arrière 22. Les deux passerelles sont prévues pour permettre aux opérateurs d'observer et/ou de manoeuvrer les deux dispositifs de manifold 9.For each cable 5 is provided on the front of the transport vessel 1 a manifold device 9 mounted on the support structure 10 of a certain height, which carries at the top two bridges 22 and 23. The two bridges are shifted in the axis of the ship, overlapping slightly, the front gateway 23 being disposed above the rear gateway 22. The two gateways are provided to allow operators to observe and / or operate the two manifold devices 9.

Chaque dispositif 9 comporte une portion tubulaire arquée 25 en forme d'un arc de cercle quelque peau inférieur à un angle de 180°. L'extrémité arrière de la portion 25 est fixée par un joint tournant à axe vertical 26 sur une portion de tuyauterie verticale 28 de la tuyauterie fixe du navire.Each device 9 comprises an arcuate tubular portion 25 in the form of an arc of some skin less than an angle of 180 °. The rear end of the portion 25 is fixed by a vertical axis rotary joint 26 on a vertical pipe portion 28 of the vessel's fixed piping.

La portion arquée 25 du dispositif de connexion ainsi monté pivotante porte, à son extrémité libre une bride de manifold 30 pour la fixation étanche du connecteur 14 du flexible et une trompette 32 qui est latéralement décalée de l'axe du connecteur, d'une distance permettant, lors d'une connexion du flexible au dispositif 9 la réception de la pinoche 17 de l'embout connecteur du flexible. La trompette est orientée parallèlement à l'axe du connecteur 30. La portion 25 du dispositif connecteur 9 du navire porte encore un treuil 34 sur lequel est enroulé un câble 35. Ce câble sera déroulé lors d'une connexion du flexible 5 au dispositif manifold 9, passe à travers la trompette 32 et sera fixé à l'extrémité de la pinoche 17. La connexion se fait alors en enroulant le câble sur le treuil 34.The arcuate portion 25 of the pivotally mounted connection device carries, at its free end, a manifold flange 30 for sealingly fastening the hose connector 14 and a trumpet 32 which is laterally offset from the connector axis by a distance allowing, during a connection of the hose to the device 9 the reception pinoche 17 of the hose connector connector. The trumpet is oriented parallel to the axis of the connector 30. The portion 25 of the connector device 9 of the ship still carries a winch 34 on which is wound a cable 35. This cable will be unwound during a connection of the hose 5 to the manifold device 9, passes through the trumpet 32 and is fixed to the end of the pinch 17. The connection is then by winding the cable on the winch 34.

Comme on le voit clairement sur les figures, pour permettre la connexion des flexibles 5 aux dispositifs de manifold 9 du navire de transport, une découpe sensiblement semi-circulaire 37 est faite dans la passerelle supérieure 23 à partir de son bord arrière 38 chevauchant le bord avant 39 de la passerelle inférieure 22, autour de l'axe de pivotement des portions arquées 25 des dispositifs de manifold 9, de façon coaxiale à ceux-ciAs is clearly seen in the figures, to allow the connection of the hoses 5 to the manifold devices 9 of the transport ship, a substantially semicircular cut 37 is made in the upper bridge 23 from its rear edge 38 overlapping the edge. before 39 of the lower bridge 22, around the pivot axis of the arcuate portions 25 of the manifold devices 9 coaxially with them

Ainsi chaque dispositif manifold 9 peut pivoter entre sa position de repos dans laquelle son connecteur 30 se trouve au-dessus de la passerelle inférieure 29 (figure 7) et sa position de travail, c'est-à-dire de connexion représentée sur la figure 6, dans laquelle le connecteur 30 passe à travers la découpe 37 pour pouvoir être connecté au flexible 5. On constate que l'angle d'arc de la portion arquée 25 de chaque dispositif de connexion 19 est inférieure de 180° d'une différence permettant une inclinaison appropriée de l'axe de la bride de manifold 30 pour une connexion facile au flexible.Thus each manifold device 9 can pivot between its rest position in which its connector 30 is above the lower gateway 29 ( figure 7 ) and its working position, that is to say of connection represented on the figure 6 in which the connector 30 passes through the cutout 37 to be connected to the hose 5. It is found that the arc angle of the arcuate portion 25 of each connecting device 19 is 180 ° less than a difference allowing an appropriate inclination of the axis of the manifold flange 30 for easy connection to the hose.

Selon une caractéristique importante de l'invention, et grâce au joint tournant à axe vertical 26 de chaque dispositif de manifold 9 du navire et à l'axe vertical de pivotement des roues de stockage 6, chaque flexible cryogénique suspendu en caténaire 5 comporte au niveau de chaque extrémité un joint tournant à axe vertical assurant que le flexible s'étende toujours sensiblement dans un plan vertical indépendamment de l'angle de désalignement α, des deux navires 1 et 2. Ceci assure une grande liberté de balancement et de lacets relatifs entre les navires. Grâce aux joints tournants à axe vertical la torsion et la flexion hors du plan vertical de la caténaire flexible (gauchissement) dans le flexible sont négligeables. Ceux-ci ne sont donc seulement exposés au très faible roulis relatif entre les navires. Pour la sécurité du flexible seul une mesure ou contrôle de la distance entre les deux extrémités de celui-ci est nécessaire.According to an important characteristic of the invention, and thanks to the vertical axis rotary joint 26 of each manifold device 9 of the ship and to the vertical axis of pivoting of the storage wheels 6, each cryogenic hose suspended catenary 5 comprises at the level of at each end a rotary joint with a vertical axis ensuring that the hose always extends substantially in a vertical plane regardless of the misalignment angle α of the two vessels 1 and 2. This ensures a great freedom of swaying and relative laces between the boats. Thanks to rotating joints with vertical axis torsion and bending out of the plane vertical of the flexible catenary (warping) in the hose are negligible. These are therefore only exposed to very low relative roll between ships. For the safety of the hose only a measurement or control of the distance between the two ends of it is necessary.

Concernant le fonctionnement du système de transfert selon l'invention, il découle des figures et de la description de la structure qui vient d'être faite. Il suffit de rappeler que, pour un transfert de gaz naturel liquéfié entre les navire de transport 1 et de stockage 2, on déroulera au moins un des câble 35 du dispositif de de manifold 9 correspondant de son treuil 34 et du flexible 5 de sa roue de stockage 6, fixe l'extrémité du câble 35 à l'extrémité de la pinoche 17 sur l'embout 13 du flexible, on roule le câble 35 sur le treuil 34 jusqu'à ce que la pinoche s'engage dans la trompette 32 du dispositif de manifold 9 qui a été bien entendu amené à pivoter de sa position de stockage représentée sur la figure 7 dans sa position de connexion selon la figure 6.Regarding the operation of the transfer system according to the invention, it follows from the figures and description of the structure that has just been made. Just remember that, for a liquefied natural gas transfer between the transport vessel 1 and storage 2, at least one of the cable 35 of the corresponding manifold device 9 of its winch 34 and the hose 5 of its wheel will be unwound. 6, fixed the end of the cable 35 at the end of the pinch 17 on the tip 13 of the hose is rolled the cable 35 on the winch 34 until the pinch engages in the trumpet 32 of the manifold device 9 which was of course made to pivot from its storage position shown on the figure 7 in its connection position according to the figure 6 .

Il est encore à noter que les flexibles ne croisent jamais l'aussière d'amarrage ce qui est très important notamment lors d'une déconnexion d'urgence. Ainsi les flexibles ne peuvent pas être endommagés en tombant sur l'aussière. Lors d'une déconnexion, les flexibles sont enroulés sur leur roue de stockageIt should also be noted that the hoses never cross the mooring haws which is very important especially during an emergency disconnection. Thus the hoses can not be damaged by falling on the hawser. When disconnecting, the hoses are wound on their storage wheel

Bien entendu des diverses modifications peuvent être apportées au système tel que décrit et représenté sur les figures. Les figures 8 et 9 illustrent une variante de réalisation selon laquelle le treuil et la trompette portant maintenant les références 34' et 32' sont prévus sur l'embout 13 de chaque flexible, tandis que la pinoche portant maintenant la référence 17' est portée par le dispositif manifold 9. On pourrait également envisager de réaliser autrement les moyens de stockage des flexibles dans leur position de repos. Il importe seulement que, dans tout mode de réalisation envisagé, un joint tournant à axe vertical soit prévu à chaque extrémité du flexible pour que celui-ci ne soit pas soumis à des contraintes de torsion et de gauchissement. Ces contraintes sont absorbées par les joints.Of course, various modifications can be made to the system as described and shown in the figures. The Figures 8 and 9 illustrate an alternative embodiment according to which the winch and the trumpet now bearing the references 34 'and 32' are provided on the tip 13 of each hose, while the pinoche bearing now the reference 17 'is carried by the manifold device 9. One could also consider otherwise realize the storage means of the hoses in their rest position. It only matters that in any embodiment A vertical axis rotating joint is provided at each end of the hose so that it is not subjected to torsional and warping stresses. These stresses are absorbed by the joints.
