Description

Domaine de l'inventionField of the invention

La présente invention se rapporte au domaine de connexion d'une ligne de puissance électrique entre un navire et un terminal. Elle concerne plus particulièrement la connexion d'une ligne de puissance électrique entre un navire méthanier et un terminal gazier.The present invention relates to the field of connection of an electric power line between a ship and a terminal. It relates more particularly to the connection of an electric power line between a LNG tanker and a gas terminal.

Arrière-plan de l'inventionBackground of the invention

Il est connu d'effectuer une connexion d'une ligne de puissance électrique entre un navire et un port, telle que celle utilisée actuellement pour relier un navire de croisière à un réseau électrique local afin d'éviter que le navire fasse tourner son groupe électrogène durant les escales.It is known to connect a power line between a ship and a port, such as the one currently used to connect a cruise ship to a local power grid to prevent the ship from rotating its generator set. during stopovers.

Le document FR 2 647 604 , qui est considéré comme étant l'état de la technique le plus proche, décrit une telle connexion, ayant les caractéristiques du préambule de la revendication 1.The document FR 2 647 604 , which is considered to be the closest state of the art, describes such a connection, having the features of the preamble of claim 1.

La figure 9 illustre très schématiquement un dispositif de connexion d'une ligne de puissance électrique entre un navire et un port selon l'art antérieur.The figure 9 schematically illustrates a device for connecting an electrical power line between a ship and a port according to the prior art.

Le dispositif comporte une ligne de puissance 101 constituée d'un ou de plusieurs câbles terminés par un ou plusieurs connecteurs 115. La ligne de puissance 101 est supportée, via des colliers 116, des suspentes 118 et des systèmes mobiles 120 par un portique 122.The device comprises a power line 101 consisting of one or more cables terminated by one or more connectors 115. The power line 101 is supported, via collars 116, lines 118 and mobile systems 120 by a gantry 122.

Ce dispositif permet ainsi de connecter un tableau électrique du bord 117 au réseau électrique local du port 5. Pour assurer la connexion, l'équipage une fois le navire 3 accosté et la ligne 101 de puissance approchée du navire 3 utilise une ou des toulines 124 pour amener le connecteur 115 de la ligne 101 de puissance à bord, puis au tableau électrique 117. La connexion du connecteur 115 sur le tableau électrique 117 se fait manuellement.This device thus makes it possible to connect an electrical board of the edge 117 to the local electrical network of the port 5. To ensure the connection, the crew once the ship 3 is docked and the line 101 of the ship's approximate power 3 uses one or more toulines 124 to bring the connector 115 of the power line 101 on board, then to the electrical board 117. The connection of the connector 115 on the electrical panel 117 is done manually.

Toutefois, ce dispositif de connexion présente plusieurs inconvénients.However, this connection device has several disadvantages.

En effet, les opérations de connexion peuvent être longues (typiquement plus d'une heure) et fastidieuses, voire dangereuse pour l'équipage ou impossible en cas de conditions météorologiques adverses.Indeed, the connection operations can be long (typically more than one hour) and tedious, even dangerous for the crew or impossible in case of adverse weather conditions.

De plus, ce genre de connexion n'est pas compatible avec les exigences de sécurité applicable à des navires et terminaux méthaniers, en particulier le besoin de déconnexion rapide, et aussi, le fait que les lignes de puissance doivent être isolée de l'ambiance extérieure qui peut être explosive.In addition, this type of connection is not compatible with the safety requirements applicable to ships and LNG terminals, in particular the need for quick disconnection, and also, the fact that the power lines must be isolated from the atmosphere. outside which can be explosive.

En outre, la puissance électrique pouvant être transférée par ce genre de connexion est limitée; typiquement à moins de 15 MW, alors que la puissance installée sur un navire méthanier peut aller jusqu'à 30 MW.In addition, the electrical power that can be transferred by this kind of connection is limited; typically less than 15 MW, while the installed capacity on a LNG ship can be up to 30 MW.

Objet et résumé de l'inventionObject and summary of the invention

La présente invention se propose donc de pallier les inconvénients précités en proposant un procédé et un dispositif de connexion sécurisée et rapide d'une ligne de puissance électrique entre un navire et un terminal.The present invention therefore proposes to overcome the aforementioned drawbacks by proposing a method and a device for secure and fast connection of an electric power line between a ship and a terminal.

Ces buts sont atteints grâce à un dispositif de connexion d'une ligne de puissance électrique entre un navire et un terminal, comportant :

  • des moyens de déroulement pour dérouler un câble de traction depuis le navire vers une extrémité de connexion de ladite ligne de puissance électrique,
  • des moyens d'amarrage pour amarrer ledit câble de traction à ladite extrémité de connexion, et
  • des moyens de traction pour tracter ladite ligne de puissance électrique vers le navire, afin de relier ladite extrémité de connexion avec une interface électrique du navire.
These goals are achieved through a connection device of a power line between a ship and a terminal, comprising:
  • unwinding means for unwinding a towing cable from the ship to a connecting end of said power line,
  • docking means for docking said pull cable to said connecting end, and
  • traction means for towing said power line to the ship, for connecting said connection end with an electrical interface of the ship.

Ainsi, la ligne de puissance peut être facilement amenée par le câble de traction depuis une zone de stockage auprès du terminal pour être connectée à l'interface électrique du navire. De plus, une déconnexion d'urgence peut être réalisée de manière simple en déroulant puis en laissant filer l'extrémité du câble de traction libérant ainsi complètement le navire du terminal.Thus, the power line can be easily brought by the traction cable from a storage area to the terminal to be connected to the electrical interface of the ship. In addition, an emergency disconnection can be carried out in a simple manner by unwinding and then letting the end of the traction cable free, thus completely freeing the ship from the terminal.

Selon un aspect de l'invention, le dispositif de connexion comporte des moyens de flottaison pour maintenir sous la surface de l'eau au moins une partie de ladite ligne de puissance.According to one aspect of the invention, the connection device comprises flotation means for maintaining below the surface of the water at least a portion of said power line.

La ligne de puissance en étant immergée n'est pas exposée aux risques d'opérations en atmosphère potentiellement explosive. Ainsi, la sécurité est entièrement compatible avec les exigences de sécurité applicable en particulier à des navires et terminaux méthaniers.The power line being submerged is not exposed to the risks of operations in a potentially explosive atmosphere. Thus, the safety is fully compatible with the safety requirements applicable in particular to ships and LNG terminals.

Le dispositif de connexion peut comporter des moyens de rappel destinés à ramener la ligne de puissance vers le terminal lorsque ladite ligne de puissance est déconnectée du navire et que le câble de traction est relâché.The connection device may include return means for bringing the power line back to the terminal when said power line is disconnected from the ship and the traction cable is released.

Ainsi, la ligne de puissance peut être facilement ramenée vers sa zone de stockage.Thus, the power line can be easily brought back to its storage area.

Avantageusement, le dispositif de connexion comporte des moyens de guidage pour guider ladite extrémité de connexion vers ladite interface électrique afin d'assurer le couplage électrique entre le navire et le terminal. Ainsi, la connexion peut être réalisée de manière automatique.Advantageously, the connection device comprises guiding means for guiding said connection end towards said electrical interface in order to ensure the electrical coupling between the ship and the terminal. Thus, the connection can be performed automatically.

En outre, le dispositif de connexion peut comporter une barge pour soutenir une partie terminale de la ligne de puissance comportant ladite extrémité de connexion, ladite barge comprenant des moyens de protection pour s'appuyer sur la coque du navire.In addition, the connecting device may comprise a barge for supporting an end portion of the power line comprising said connecting end, said barge comprising protection means for resting on the hull of the ship.

Ainsi, la ligne de puissance peut être amenée au voisinage du navire pour être connectée de manière simple et en toute sécurité.Thus, the power line can be brought to the vicinity of the ship to be connected in a simple and safe manner.

La coque de ladite barge peut avantageusement comporter une ouverture permettant de stocker ladite partie terminale de la ligne de puissance sous la barge.The hull of said barge may advantageously comprise an opening for storing said end portion of the power line under the barge.

Ainsi, le support de la ligne de puissance est facilité et la sécurité augmentée.Thus, the support of the power line is facilitated and the security increased.

Selon un aspect particulier, ladite partie terminale de la ligne de puissance est stockée sur la barge et comporte une double enveloppe.In a particular aspect, said end portion of the power line is stored on the barge and has a double envelope.

Ainsi, la partie aérienne de la ligne de puissance peut être protégée des risques dus à une atmosphère potentiellement explosive. De plus, la double enveloppe permet le refroidissement par un fluide (par exemple l'eau) des conducteurs électriques de la ligne de puissance.Thus, the aerial part of the power line can be protected from risks due to a potentially explosive atmosphere. In addition, the double jacket allows cooling by a fluid (eg water) of the electrical conductors of the power line.

Selon un autre aspect particulier, ladite barge comporte un caisson muni de joints entourant la partie émergée de la ligne de puissance et formant avec la coque du navire, la coque de la barge et la surface du plan d'eau une zone étanche vis-à-vis de l'extérieur.According to another particular aspect, said barge comprises a box provided with joints surrounding the emergent portion of the power line and forming with the hull of the ship, the hull of the barge and the surface of the body of water a sealed zone vis-à-vis -vis from the outside.

Ceci permet d'isoler de l'atmosphère, éventuellement explosive, la partie émergée de la ligne de puissance augmentant ainsi la sécurité des manoeuvres de connexion.This allows to isolate the potentially explosive atmosphere, the emerging part of the power line thus increasing the safety of the connection maneuvers.

Avantageusement, le dispositif de connexion comporte un ventilateur, disposé sur le navire ou la barge, destiné à mettre ladite zone étanche en surpression, ledit ventilateur prélevant de l'air depuis une zone hors gaz. Ainsi, la sécurité est davantage augmentée.Advantageously, the connection device comprises a fan, disposed on the ship or the barge, for putting said sealed area under overpressure, said fan drawing air from a non-gas zone. Thus, security is increased further.

Le dispositif de connexion peut comporter une source de gaz inerte destiné à remplir ladite zone étanche de gaz inerte.The connection device may comprise a source of inert gas intended to fill said sealed zone with inert gas.

Les moyens de traction du dispositif de connexion peuvent comporter un treuil disposé sur le navire pour tracter via le câble de traction l'extrémité de connexion de ladite ligne de puissance.The traction means of the connection device may comprise a winch arranged on the ship for towing via the pulling cable the connecting end of said power line.

Avantageusement, les moyens de traction comportent un moyen de suspension destiné à compenser le poids de ladite ligne de puissance.Advantageously, the traction means comprise a suspension means intended to compensate for the weight of said power line.

L'invention vise également un navire comportant une interface électrique destiné à être couplé électriquement à un terminal, le navire comportant :

  • docking means for docking said pull cable to said connecting end, and
  • traction means for drawing said power line to the ship to connect said connection end with said electrical interface.

Selon un mode de réalisation, la coque du navire comporte un conduit pour le passage de la ligne de puissance, ledit conduit débouchant sous la ligne de flottaison.According to one embodiment, the hull of the ship comprises a conduit for the passage of the power line, said conduit opening under the waterline.

Ainsi, le conduit en débouchant sous la ligne de flottaison permet de protéger la ligne de puissance de toute ambiance explosive.Thus, the duct opening under the waterline can protect the power line of any explosive atmosphere.

Avantageusement, l'extrémité du câble de traction comporte une bouée submersible.Advantageously, the end of the traction cable comprises a submersible buoy.

Ainsi, une fois passée l'ouverture du conduit, l'extrémité du câble tracteur peut être facilement ramenée à la surface pour y être connectée à l'extrémité de connexion de ladite ligne de puissance.Thus, once past the opening of the conduit, the end of the towing cable can be easily brought to the surface to be connected to the connection end of said power line.

Selon un autre mode de réalisation, la coque du navire comporte un conduit pour le passage de la ligne de puissance débouchant au dessus de la ligne de flottaison et en ce que le conduit est prolongé par une enveloppe étanche au gaz.According to another embodiment, the hull of the ship comprises a conduit for the passage of the power line opening above the waterline and in that the conduit is extended by a gas-tight envelope.

Avantageusement, ledit conduit comporte une trappe de protection étanche.Advantageously, said conduit comprises a sealed protective hatch.

Avantageusement, le navire comporte des moyens de guidage comprenant des moyens d'accostage assurant le guidage de ladite extrémité de connexion de ladite ligne de puissance vers des moyens de prise de l'interface de connexion électrique. Ainsi, la connexion peut être réalisée rapidement et en toute sécurité.Advantageously, the vessel comprises guiding means comprising docking means ensuring the guiding of said connection end of said power line to means of socket of the electrical connection interface. Thus, the connection can be made quickly and safely.

Ladite interface de connexion électrique peut comporter un capot de protection étanche.Said electrical connection interface may comprise a sealed protective cover.

Avantageusement, le navire comporte un poste de commande accessible via une porte étanche du navire.Advantageously, the ship has a control station accessible via a sealed door of the ship.

En particulier, le navire peut être un navire méthanier.In particular, the ship can be a LNG tanker.

L'invention vise aussi un dispositif de couplage électrique comportant une ligne de puissance électrique destiné à relier un navire à un terminal, comportant des moyens de flottaison pour maintenir sous la surface de l'eau au moins une partie de ladite ligne de puissance électrique lors de son transport entre le terminal et le navire.The invention also relates to an electrical coupling device comprising an electrical power line intended to connect a ship to a terminal, comprising flotation means for keeping under the water surface at least a portion of said electric power line when of its transport between the terminal and the ship.

Description détaillée de modes de réalisationDetailed description of embodiments

Conformément à l'invention, la figure 1 illustre très schématiquement un dispositif de connexion d'une ligne 1 de puissance électrique entre un navire 3 et un terminal 5.According to the invention, the figure 1 schematically illustrates a device for connecting a line 1 of electrical power between a ship 3 and a terminal 5.

Le dispositif de connexion comporte des moyens de déroulement 7, des moyens d'amarrage 9 et des moyens de traction 11.The connection device comprises unwinding means 7, docking means 9 and traction means 11.

Les moyens de déroulement 7 sont destinés à dérouler un câble 13 de traction depuis le navire 3 vers une extrémité de connexion 15 comportant le connecteur 15a de la ligne 1 de puissance électrique. Cette ligne 1 de puissance peut comporter une pluralité de câbles de liaison électrique et peut être rangée dans une zone de stockage auprès du terminal 5. On notera que la capacité d'échange électrique pouvant être réalisé via cette ligne 1 de puissance électrique peut atteindre jusqu'à 30 MW.The unwinding means 7 are intended to unwind a pulling cable 13 from the ship 3 to a connecting end 15 comprising the connector 15a of the power line 1. This power line 1 may comprise a plurality of electrical connection cables and may be stored in a storage area near the terminal 5. Note that the electrical exchange capacity that can be achieved via this line 1 of electrical power can reach up to at 30 MW.

Les moyens d'amarrage 9 sont destinés à amarrer le câble 13 de traction à l'extrémité de connexion 15 de la ligne 1 de puissance électrique.The docking means 9 are intended to moor the traction cable 13 at the connecting end 15 of the power line 1.

Les moyens de traction 11 sont destinés à tracter via le câble 13 de traction, la ligne 1 de puissance électrique vers un point ou une zone 17 de connexion du navire 3 afin de relier l'extrémité de connexion 15 avec une interface électrique 17a. Ainsi, un couplage électrique peut être assuré entre le navire 3 et le terminal 5.The traction means 11 are intended to pull via the pulling cable 13, the line 1 of electrical power to a point or a connection area 17 of the ship 3 to connect the connection end 15 with an electrical interface 17a. Thus, an electrical coupling can be provided between the ship 3 and the terminal 5.

En outre, ce couplage électrique peut être déconnecté rapidement et de manière simple en déroulant puis en laissant filer l'extrémité du câble 13 de traction. Ainsi, le navire 3 peut être complètement libéré du terminal 5.In addition, this electrical coupling can be disconnected quickly and simply by unwinding and then letting the end of the traction cable 13 run. Thus, the ship 3 can be completely released from the terminal 5.

La figures 2 illustre très schématiquement un exemple de dispositif de connexion de la ligne 1 de puissance électrique entre le navire 3 et le terminal 5 dans lequel la ligne 1 de puissance est immergée dans l'eau.The figures 2 illustrates very schematically an example of connection device of the line 1 of electrical power between the vessel 3 and the terminal 5 in which the power line 1 is immersed in water.

En effet, le dispositif de connexion ou de couplage électrique selon cet exemple comporte des moyens de flottaison 21, par exemple une série de flotteurs 21, pour maintenir sous la surface 23 libre de l'eau au moins une partie de la ligne 1 de puissance lors de son transport entre le terminal 5 et le navire 3.Indeed, the electrical connection or coupling device according to this example comprises flotation means 21, for example a series of floats 21, to maintain under the free surface 23 of water at least a portion of the power line 1 during transport between the terminal 5 and the ship 3.

Ainsi, la ligne 1 de puissance en étant immergée n'est pas exposée aux risques d'opérations en atmosphère potentiellement explosive au cas où le terminal 5 est par exemple un terminal gazier et/ou le navire 3 est du type méthanier.Thus, the power line 1 being immersed is not exposed to the risks of operations in a potentially explosive atmosphere in the case where the terminal 5 is for example a gas terminal and / or the vessel 3 is of the LNG type.

En outre, le dispositif de connexion selon cet exemple comporte une embarcation de lamanage 25 qui correspond aux moyens de déroulement 7 et d'amarrage 9.In addition, the connection device according to this example comprises a mooring boat 25 which corresponds to the unwinding means 7 and docking means 9.

Ainsi, les manoeuvres de connexion sont aussi simples que celles nécessaires pour la mise en place ou le largage des lignes d'amarrages et ne nécessitent pas d'effectifs supplémentaires.Thus, the connection maneuvers are as simple as those necessary for the establishment or the release of mooring lines and do not require additional manpower.

La figures 3 illustre très schématiquement un autre exemple de dispositif de connexion qui se distingue de celui de la figure 2 par le fait qu'il comporte en outre des moyens de rappel 27 et une barge 31.The figures 3 schematically illustrates another example of connection device that is different from that of the figure 2 in that it further comprises return means 27 and a barge 31.

Avantageusement, les moyens de rappel 27 sont destinés à ramener la ligne 1 de puissance vers le terminal 5 lorsque la ligne 1 de puissance est déconnectée du navire 3 et que le câble de traction 13 est relâché. Ces moyens de rappel 27 peuvent correspondre à un câble de rappel 27 (comme illustré) ou à l'utilisation de l'embarcation de lamanage 25 ou à un moyen de propulsion (non représenté) embarqué sur les moyens de flottaison 21 ou la barge 31.Advantageously, the return means 27 are intended to return the power line 1 to the terminal 5 when the power line 1 is disconnected from the ship 3 and the traction cable 13 is released. These return means 27 may correspond to a return cable 27 (as illustrated) or to the use of the mooring boat 25 or to a propulsion means (not shown) embedded on the flotation means 21 or the barge 31 .

La barge 31 est destinée à soutenir une partie terminale 33 de la ligne 1 de puissance comportant l'extrémité de connexion 15. Ainsi, la barge 31 peut comporter des moyens de support 34 pour supporter le dernier tronçon aérien de la partie terminale 33 de la ligne 1 de puissance.The barge 31 is intended to support an end portion 33 of the power line 1 having the connecting end 15. Thus, the barge 31 may comprise support means 34 for supporting the last aerial section of the end portion 33 of the line 1 of power.

De plus, la barge 31 peut comprendre des moyens de protection 35 ou de défenses lui permettant de s'appuyer sur la coque 37 du navire 3.In addition, the barge 31 may comprise protection means 35 or defenses allowing it to rest on the hull 37 of the ship 3.

Eventuellement, la partie terminale 33 de la ligne 1 de puissance qui est stockée sur la barge 31 peut comporter une double enveloppe.Optionally, the end portion 33 of the power line 1 which is stored on the barge 31 may comprise a double envelope.

En effet, pour éviter les risques dans une atmosphère potentiellement explosive, la partie terminale 33 aérienne de la ligne 1 de puissance peut éventuellement être munie d'une double enveloppe 36 telle que illustrée sur la figure 4. Outre la création d'une double barrière vis-à-vis de l'extérieur, la double enveloppe 36 permet avantageusement, le refroidissement des conducteurs électriques de la ligne 1 de puissance par de l'eau ou par un autre fluide.Indeed, to avoid the risks in a potentially explosive atmosphere, the aerial terminal portion 33 of the power line 1 may optionally be provided with a double envelope 36 as shown in FIG. figure 4 . In addition to the creation of a double barrier vis-à-vis the outside, the jacket 36 advantageously allows the cooling of the electrical conductors of the power line 1 by water or other fluid.

En variante (voir figures 6A et 6B) la coque de la barge 31 peut comporter une ouverture permettant de stocker la partie terminale 33 de la ligne 1 de puissance sous la barge 31. Selon cette dernière configuration, les moyens de support 34 peuvent être simplifiés ou même supprimés.Alternatively (see Figures 6A and 6B ) the hull of the barge 31 may include an opening for storing the end portion 33 of the power line 1 under the barge 31. According to the latter configuration, the support means 34 may be simplified or even deleted.

Les figures 5A à 5D illustrent les différentes étapes de connexion ou de déconnexion entre le navire 3 et le terminal 5 selon le dispositif de connexion de la figure 3.The Figures 5A to 5D illustrate the different steps of connection or disconnection between the ship 3 and the terminal 5 according to the connecting device of the figure 3 .

En effet, la figure 5A montre l'étape initiale ou l'embarcation de lamanage 25 amène le câble tracteur 13 depuis le navire 3 vers la barge 31 pour l'accrocher à l'extrémité de connexion 15 de la ligne 1 de puissance.Indeed, the Figure 5A shows the initial step or the mooring boat 25 brings the towing cable 13 from the ship 3 to the barge 31 to hang it at the connecting end 15 of the power line 1.

La figure 5B montre l'étape de traction de la barge 31 et des flotteurs 21 supportant la ligne 1 de puissance immergée, de leur zone de stockage vers le navire 3. En effet, les moyens de traction 11 peuvent comporter un treuil (voir figure 7A) disposé sur le navire 3 pour tracter via le câble 13 de traction l'extrémité de connexion 15 de la ligne 1 de puissance. Ainsi, pendant l'étape de traction au moins une partie de la ligne 1 de puissance électrique est maintenue sous la surface 23 de l'eau. On notera que cette étape est analogue à une simple opération classique qui consiste à tendre des amarres.The Figure 5B shows the pulling step of the barge 31 and the floats 21 supporting the submerged power line 1, from their storage area to the ship 3. Indeed, the traction means 11 may comprise a winch (see FIG. Figure 7A ) arranged on the ship 3 to tow via the pulling cable 13 the connecting end 15 of the power line 1. Thus, during the step of pulling at least a portion of the line 1 of electrical power is maintained under the surface 23 of the water. It will be noted that this step is analogous to a simple conventional operation which consists of straightening moorings.

La figure 5C montre l'étape de couplage électrique entre le navire 3 et le terminal 5. Selon cette étape, le câble tracteur 13 tire l'extrémité de connexion 15 de la ligne 1 de puissance jusqu'à ce que la barge 31 s'appuie contre la coque 37 du navire 3 et le connecteur 15a se connecte sur l'interface électrique 17a du navire 3.The Figure 5C shows the electrical coupling step between the ship 3 and the terminal 5. According to this step, the towing cable 13 pulls the connecting end 15 of the power line 1 until the barge 31 bears against the hull 37 of the ship 3 and the connector 15a connects to the electrical interface 17a of the ship 3.

Par ailleurs, la déconnexion ou le découplage entre le navire 3 et le terminal 5 peut être réalisée de manière simple en libérant l'extrémité de connexion 15 de la ligne 1 de puissance de l'interface électrique 17a et du câble tracteur 13. Ensuite, la barge 31 et les flotteurs 21 supportant la ligne 1 de puissance, peuvent être ramenés vers leurs zones de stockage, par les moyens de rappel 27, par exemple par le câble de rappel 27. En variante, la barge 31 et les flotteurs 21 peuvent être ramenés par l'embarcation de lamanage 25 ou par un moyen de propulsion (non représenté) embarqué sur la barge 31.Furthermore, the disconnection or decoupling between the ship 3 and the terminal 5 can be carried out in a simple manner by releasing the connection end 15 of the power line 1 of the electrical interface 17a and the traction cable 13. Next, the barge 31 and the floats 21 supporting the power line 1, can be brought back to their storage areas, by the return means 27, for example by the return cable 27. Alternatively, the barge 31 and the floats 21 may be brought back by the mooring boat 25 or by a propulsion means (not shown) embarked on the barge 31.

On notera que les opérations de connexion et de déconnexion sont similaires aux opérations d'amarrage classiques et peuvent être réalisés par les lamaneurs et les membres de l'équipage assurant les manoeuvres d'amarrage.It should be noted that the connection and disconnection operations are similar to conventional mooring operations and can be carried out by the mooring crews and the crew members performing the mooring maneuvers.

La figure 5D montre une étape de déconnexion rapide. En effet, en cas d'urgence, une fois l'extrémité de connexion 15 est libérée, le câble de traction 13 peut être relâché pour laisser descendre la partie aérienne de la ligne 1 de puissance sur les moyens de support 34 de la barge 31.The figure 5D shows a quick disconnect step. Indeed, in case of emergency, once the connection end 15 is released, the traction cable 13 can be released to let down the aerial part of the power line 1 on the support means 34 of the barge 31 .

Ainsi, en cas d'urgence, le navire 3 peut être en très peu de temps (quelques minutes), complètement libéré du terminal 5 en déroulant puis en laissant filer l'extrémité 13a du câble de traction 13. Ensuite, les moyens de rappel 27 peuvent éloigner la ligne 1 de puissance du navire 3.Thus, in case of emergency, the ship 3 can be in a very short time (a few minutes), completely released from the terminal 5 by unwinding and then leaving the end 13a of the pulling cable 13. Then, the return means 27 can move the power line 1 away from the ship 3.

La figure 6A illustre une variante de la barge 31 permettant de répondre, en particulier, au besoin d'isoler de l'atmosphère, éventuellement explosive, la partie émergée de la ligne 1 de puissance.The Figure 6A illustrates a variant of the barge 31 to meet, in particular, the need to isolate the atmosphere, possibly explosive, the emerging portion of the power line 1.

Selon cet exemple, la barge 31 comporte un caisson 61 étanche muni de joints 63, qui entoure la partie émergée ou terminale 33 de la ligne 1 de puissance. Ainsi, ce caisson 61 forme avec la coque 37 du navire 3, la coque 65 de la barge 31 et la surface 23 du plan d'eau, une zone étanche ou un volume fermé étanche 67 vis-à-vis de l'extérieur.According to this example, the barge 31 comprises a sealed box 61 provided with seals 63, which surrounds the emergent or terminal portion 33 of the line 1 of power. Thus, this box 61 forms with the hull 37 of the ship 3, the hull 65 of the barge 31 and the surface 23 of the body of water, a sealed zone or a sealed closed volume 67 vis-à-vis the outside.

Eventuellement, pour se protéger de manière encore plus efficace vis-à-vis d'un risque d'atmosphère explosive, on peut utiliser un ventilateur (non représenté) placé sur le navire 3 ou sur la barge 31. Ce ventilateur est destiné à prélever de l'air depuis une zone hors gaz pour mettre la zone étanche 67 en légère surpression.Optionally, to protect even more effectively vis-à-vis a risk of explosive atmosphere, can be used a fan (not shown) placed on the ship 3 or on the barge 31. This fan is intended to collect air from a non-gas zone to put the tight zone 67 in slight overpressure.

Une autre solution pourrait être d'utiliser pour cette fonction une source de gaz inerte, par exemple d'azote, pour remplir la zone étanche 67 de gaz inerte. Ce gaz inerte peut être disponible soit à bord du navire 3, soit à bord de la barge 31, soit auprès du terminal 5.Another solution could be to use for this function a source of inert gas, for example nitrogen, to fill the sealed zone 67 of inert gas. This inert gas may be available either aboard the ship 3, or aboard the barge 31, or at the terminal 5.

Cet exemple montre que les moyens de traction 11 comportent un treuil 45 pour tracter via le câble 13, l'extrémité de connexion 15 de la ligne 1 de puissance.This example shows that the traction means 11 comprise a winch 45 for towing via the cable 13, the connecting end 15 of the power line 1.

Eventuellement, les moyens de traction 11 peuvent comporter des moyens de suspension 69 destinés à compenser le poids de la ligne 1 de puissance.Optionally, the traction means 11 may comprise suspension means 69 intended to compensate for the weight of the power line 1.

En effet, les moyens de suspension 69 permettent de faciliter les manoeuvres en compensant le poids de la ligne 1 de puissance par un système de suspension relié à des poids ou des ressorts 71.Indeed, the suspension means 69 make it easier to maneuver by compensating the weight of the power line 1 by a suspension system connected to weights or springs 71.

Selon la configuration de l'exemple de la figure 6A, il est avantageux que la ligne 1 de puissance soit stockée sous la barge 31.According to the configuration of the example of the Figure 6A it is advantageous for the power line 1 to be stored under the barge 31.

En effet, la figure 6B montre que la coque de la barge 31 est munie d'une ouverture 73 ou que la barge 31 est de type catamaran pour permettre le stockage de la ligne 1 de puissance en la laissant suspendue sous la barge 31.Indeed, the Figure 6B shows that the hull of the barge 31 is provided with an opening 73 or that the barge 31 is catamaran type to allow the storage of the power line 1 by leaving it suspended under the barge 31.

La figure 6C illustre une autre variante de la barge 31 qui se distingue de celui de la figure 6A uniquement par le fait que la barge 31 comporte un caisson 61a étanche suffisamment volumineux pour assurer la protection et le stockage de la ligne 1 de puissance à l'intérieur et hors de l'eau. Ainsi, lorsque la barge 31 est accolée au navire 3 et la ligne 1 de puissance activée, le caisson 61a étanche peut assurer une protection vis-à-vis d'une atmosphère potentiellement explosive.The Figure 6C illustrates another variant of the barge 31 which differs from that of the Figure 6A only by the fact that the barge 31 comprises a watertight box 61a sufficiently large to ensure the protection and storage of power line 1 inside and out of the water. Thus, when the barge 31 is contiguous to the ship 3 and the power line 1 activated, the box 61a sealed can provide protection vis-à-vis a potentially explosive atmosphere.

La figure 7A illustre avec plus de détail, la zone 17 de connexion à bord du navire 3. Cet exemple montre que le dispositif de connexion peut comporter des moyens de guidage 41a à 41d permettant de guider et de relier l'extrémité de connexion 15 avec l'interface électrique 17a du navire 3 pour assurer le couplage électrique entre le navire 3 et le terminal 5 de manière automatique.The Figure 7A illustrates in greater detail, the connection zone 17 on board the ship 3. This example shows that the connection device may comprise guide means 41a to 41d for guiding and connecting the connection end 15 with the interface 17a of the ship 3 to ensure the electrical coupling between the ship 3 and the terminal 5 automatically.

En effet, la zone 17 de connexion peut correspondre à une ouverture 43 dans la coque 37 du navire 3, comportant les moyens de traction 11 qui peuvent comprendre le treuil 45, les moyens de guidage 41a à 41d, l'interface électrique 17a, et un poste de commande 47.Indeed, the connection zone 17 may correspond to an opening 43 in the hull 37 of the ship 3, comprising the traction means 11 which may comprise the winch 45, the guide means 41a to 41d, the electrical interface 17a, and a command post 47.

A titre d'exemple, cette figure montre que la ligne 1 de puissance comporte deux câbles électriques dont les extrémités sont tractées par le treuil 45 via le câble 13. Bien entendu, la ligne de puissance peut comprendre un nombre quelconque de câbles électriques.For example, this figure shows that the power line 1 comprises two electrical cables whose ends are pulled by the winch 45 via the cable 13. Of course, the power line may include any number of electric cables.

Le poste de commande 47 peut être accessible via une porte étanche 49 pour permettre à un membre 50 de l'équipage de piloter à l'aide du treuil 45 la manoeuvre de connexion ou de déconnexion.The control station 47 can be accessed via a sealed door 49 to allow a member 50 of the crew to control the winch 45 connection or disconnection maneuver.

Les moyens de guidage 41a à 41d peuvent comporter des moyens d'accostage mâle 41b et femelle 41a assurant le guidage mécanique final de l'extrémité de connexion 15 vers des moyens de prise 51 de l'interface électrique 17a pour connecter le ou les connecteurs 15a à ces moyens de prise 51.The guiding means 41a to 41d may comprise male docking means 41b and female 41a providing the final mechanical guidance of the connection end 15 to the engagement means 51 of the electrical interface 17a to connect the connector or connectors 15a. to these engagement means 51.

Eventuellement, les moyens de guidage 41a à 41d peuvent comporter une poulie 41c intermédiaire et une rampe 41d pour faciliter le guidage et le centrage du ou des connecteurs 15a dans les moyens de prise 51.Optionally, the guiding means 41a to 41d may comprise an intermediate pulley 41c and a ramp 41d to facilitate the guiding and centering of the connector (s) 15a in the engagement means 51.

En outre, l'ouverture 43 dans la coque 37 peut être munie d'un capot de fermeture étanche 53 permettant de l'obturer lorsque l'interface électrique 17a est inactive.In addition, the opening 43 in the shell 37 may be provided with a sealing cap 53 for closing it when the electrical interface 17a is inactive.

La figure 7B illustre un autre mode de réalisation qui se distingue de celui de la figure 7A par le fait que la zone 17 de connexion est située à l'intérieur du navire 3.The Figure 7B illustrates another embodiment which differs from that of the Figure 7A in that the connection zone 17 is located inside the ship 3.

En effet, selon cet exemple, la coque 37 du navire 3 comporte un conduit 81 pour le passage de la ligne 1 de puissance. Ce conduit 81 est muni d'une trappe de fermeture étanche 54 permettant de l'obturer lorsque l'interface électrique 17a est inactive.Indeed, according to this example, the hull 37 of the ship 3 comprises a conduit 81 for the passage of the power line 1. This duct 81 is provided with a sealing flap 54 for closing it when the electrical interface 17a is inactive.

Comme précédemment, les moyens de guidage 41a à 41d peuvent comporter des moyens d'accostage mâle 41b et femelle 41a assurant le guidage mécanique final de l'extrémité de connexion 15 vers les moyens de prise 51 de l'interface électrique 17a pour connecter le ou les connecteurs 15a à ces moyens de prise 51.As previously, the guiding means 41a to 41d may comprise male docking means 41b and female 41a providing the final mechanical guidance of the connection end 15 to the engagement means 51 of the electrical interface 17a for connecting the or the connectors 15a to these engagement means 51.

Selon cet exemple, les moyens d'accostage femelle 41a de l'interface électrique 17a sont disposés de manière à recevoir l'extrémité de connexion 15 de la ligne 1 de puissance sortant sensiblement verticalement du conduit 81.According to this example, the female docking means 41a of the electrical interface 17a are arranged to receive the connection end 15 of the power line 1 exiting substantially vertically from the conduit 81.

La figure 8A illustre de manière schématique un navire 3 dont la coque 37 comporte un conduit 81 pour le passage de la ligne 1 de puissance, débouchant sous la ligne 23 de flottaison.The figure 8A schematically illustrates a vessel 3 whose hull 37 comprises a conduit 81 for the passage of the power line 1, opening under the waterline 23.

En effet, la ligne 1 de puissance peut être tirée à l'intérieur de la coque 37 du navire par le treuil 45 via le conduit 81 étanche qui peut de plus être mis en surpression d'air ou d'azote au moyen d'un ventilateur 83. Le fait que l'ouverture 81a de ce conduit 81 se situe sous la ligne 23 de flottaison permet de protéger la ligne 1 de puissance de toute ambiance explosive.Indeed, the power line 1 can be pulled inside the hull 37 of the vessel by the winch 45 via the conduit 81 sealed which can be further overpressured air or nitrogen by means of a 83. The fact that the opening 81a of this conduit 81 is below the waterline 23 protects the power line 1 of any explosive atmosphere.

On notera que selon cette configuration, une extrémité du câble tracteur 13 est munie d'une bouée submersible 85 qui permet, une fois passée l'ouverture 81a, de ramener cette extrémité du câble tracteur 13 à la surface pour y être connectée par l'équipe de lamanage à l'extrémité de connexion 15 de la ligne 1 de puissance.Note that according to this configuration, one end of the towing cable 13 is provided with a submersible buoy 85 which allows, once past the opening 81a, bring this end of the towing cable 13 to the surface to be connected by the mooring team to the connecting end 15 of the power line 1.

La figure 8B montre que l'extrémité 13a du câble tracteur 13, éventuellement munie d'une bouée 85, peut rester sur le coté du navire 3 lorsque le navire fait route. Lorsque la connexion doit être établie, cette extrémité 13a est envoyée vers le canot de lamanage qui peut la relier à l'extrémité de connexion 15 de la ligne 1 de puissance et ainsi assurer la mise en place de la ligne 1 de puissance, même si l'ouverture 81a du conduit 81 se trouve sous la ligne 23 de surface de l'eau.The Figure 8B shows that the end 13a of the towing cable 13, possibly equipped with a buoy 85, can remain on the side of the ship 3 when the ship is under way. When the connection has to be established, this end 13a is sent to the mooring canoe which can connect it to the connecting end 15 of the power line 1 and thus ensure the introduction of the power line 1, even if the opening 81a of the conduit 81 is under the surface line 23 of the water.

La figure 8C illustre une variante de la figure 8A. Selon cet exemple, la coque 37 du navire 3 comporte un conduit 91 pour le passage de la ligne 1 de puissance qui débouche au dessus de la ligne 23 de flottaison. Selon cet exemple, la partie terminale 33 de la ligne 1 de puissance se trouvant à l'extérieur du conduit 91 peut être protégé d'une atmosphère éventuellement explosive par une enveloppe 93 flexible étanche au gaz prolongeant le conduit 91, ou alternativement par un caisson 61 (selon la figure 6A) ou un caisson 61a (selon la figure 6C).The Figure 8C illustrates a variant of the figure 8A . According to this example, the hull 37 of the ship 3 comprises a conduit 91 for the passage of the power line 1 which opens above the waterline 23. According to this example, the end portion 33 of the power line 1 located outside the conduit 91 can be protected from a potentially explosive atmosphere by a gas-tight flexible envelope 93 extending the conduit 91, or alternatively by a box 61 (according to Figure 6A ) or a box 61a (depending on the Figure 6C ).

On notera que selon les configurations illustrées dans les figures 8A à 8C, le guidage de la ligne 1 de puissance est simplifié, car il est en partie assuré par le conduit 81 ou 91.It will be noted that according to the configurations illustrated in the Figures 8A to 8C , the guidance of the power line 1 is simplified, because it is partly provided by the conduit 81 or 91.

Ainsi, conformément à l'invention, la ligne 1 de puissance est adaptée pour alimenter le navire 3 en courant électrique depuis le terminal 5 ou réciproquement pour alimenter le terminal 5 depuis le navire 3.Thus, in accordance with the invention, the power line 1 is adapted to supply the ship 3 with electric power from the terminal 5 or vice versa to feed the terminal 5 from the ship 3.

En effet, le navire 3 (par exemple un navire méthanier) peut comporter un générateur électrique (non représenté) pour alimenter le terminal 5 en courant électrique via la ligne 1 de puissance. Ainsi, une partie de l'énergie produite par le générateur électrique du navire 3 peut être fournie au terminal 5 gazier.Indeed, the ship 3 (for example a methane tanker) may comprise an electric generator (not shown) for supplying the terminal 5 with electrical power via the power line 1. Thus, a portion of the energy produced by the ship's electric generator 3 can be supplied to the gas terminal.

Avantageusement, la présente invention, fourni des moyens de connexion électrique aussi facile à mettre en oeuvre qu'une amarre.Advantageously, the present invention provides electrical connection means as easy to implement as a mooring.

Ces moyens de connexion électrique comporte les avantages suivants :

  • un temps de manoeuvres de connexion et de déconnexion inférieur à environ 15 minutes ;
  • des manoeuvres aussi simples que celles nécessaires pour la mise en place ou le largage des lignes d'amarrages, ne nécessitant pas d'effectifs supplémentaires ;
  • une capacité d'échange électrique de l'ordre de 30 MW ; et
  • compatible avec les impératives de sécurité applicable aux navires et terminaux méthaniers.
These electrical connection means has the following advantages:
  • a connection and disconnection time of less than about 15 minutes;
  • maneuvers as simple as those necessary for setting up or releasing the mooring lines, requiring no additional manpower;
  • an electrical exchange capacity of the order of 30 MW; and
  • compatible with the safety requirements applicable to ships and LNG terminals.
