Description

DESCRIPTION  DESCRIPTION
TITRE : Dispositif de récupération d’un véhicule TITLE: Vehicle recovery device
La présente invention concerne un dispositif de récupération d’un véhicule, par exemple un drone de surface sans pilote à bord (ou USV de l’anglais « Unmanned Surface Vessel ») ou un drone sous-marin sans pilote à bord (ou UUV de l’anglais « Unmanned Underwater Vessel » ou UAV de l’anglais « Unmanned Autonomous Vehicle »). The present invention relates to a device for recovering a vehicle, for example an unmanned surface drone on board (or USV for “Unmanned Surface Vessel”) or an unmanned underwater drone on board (or UUV of English “Unmanned Underwater Vessel” or UAV from English “Unmanned Autonomous Vehicle”).
WO97/39940A1 et FR2556309A1 proposent des dispositifs de mise à l’eau et de récupération d’un véhicule comprenant un berceau flottant (aussi appelé « cage flottante » ou « dock flottant ») configuré pour recevoir et soutenir le véhicule, le berceau flottant étant configuré pour être manipulé à l’aide d’un moyen de levage prévu sur un navire ou une plateforme flottante ou une installation fixe, afin d’être descendu sur l’eau à partir du navire, de la plateforme flottante ou de l’installation fixe pour la mise à l’eau du véhicule, ou remonté sur le navire, la plateforme flottante ou l’installation fixe, pour la récupération du véhicule.  WO97 / 39940A1 and FR2556309A1 propose devices for launching and recovering a vehicle comprising a floating cradle (also called “floating cage” or “floating dock”) configured to receive and support the vehicle, the floating cradle being configured to be manipulated by means of a lifting means provided on a ship or a floating platform or a fixed installation, in order to be lowered onto the water from the ship, the floating platform or the installation fixed for launching the vehicle, or reassembled on the ship, the floating platform or the fixed installation, for recovering the vehicle.
Lors d’opérations de récupération d’un véhicule, le berceau flottant est mis à l’eau, le véhicule rentre dans le berceau, puis le berceau est remonté sur le navire, la plateforme flottante ou l’installation fixe.  During vehicle recovery operations, the floating cradle is put in the water, the vehicle enters the cradle, then the cradle is reassembled on the ship, the floating platform or the fixed installation.
Toutefois, il peut s’avérer difficile de faire entrer le véhicule dans le berceau, du fait de la houle, en particulier lorsque la mer est dans un état formé et/ou que le véhicule doit être remonté sur un navire en mouvement, du fait de mouvements relatifs inévitables entre le navire, la plateforme flottante ou l’installation fixe, le berceau mis à l’eau et le véhicule.  However, it can be difficult to get the vehicle into the cradle, due to the swell, especially when the sea is in a formed state and / or the vehicle has to be reassembled on a moving ship, due to inevitable relative movements between the ship, the floating platform or the fixed installation, the cradle launched and the vehicle.
Un des buts de l’invention est de proposer un dispositif de récupération d’un véhicule facilitant l’opération de récupération.  One of the aims of the invention is to propose a device for recovering a vehicle facilitating the recovery operation.
A cet effet, l’invention propose un dispositif de récupération d’un véhicule, le dispositif de récupération comprenant un berceau flottant prévu pour recevoir et supporter le véhicule, le berceau possédant une entrée pour le véhicule située à une extrémité arrière du berceau et délimitée entre deux parties latérales, le berceau étant configuré ou configurable avec une extension latérale arrière s’étendant vers l’arrière à partir d’une des deux parties latérales, l’autre partie latérale étant dépourvue d’extension latérale arrière. L’extension latérale arrière s’étendant à partir de l’une des deux parties latérales délimitant l’entrée du berceau permet de guider la proue (ou étrave) d’un véhicule cherchant à entrer dans le berceau, en permettant d’approcher le véhicule obliquement par rapport au berceau, de manière que l’étrave vienne en contact avec l’extension latérale arrière et soit déviée vers l’entrée du berceau. To this end, the invention provides a device for recovering a vehicle, the recovery device comprising a floating cradle designed to receive and support the vehicle, the cradle having an inlet for the vehicle located at a rear end of the cradle and delimited between two lateral parts, the cradle being configured or configurable with a rear lateral extension extending rearwards from one of the two lateral parts, the other lateral part being devoid of rear lateral extension. The rear lateral extension extending from one of the two lateral parts delimiting the entry of the cradle makes it possible to guide the prow (or bow) of a vehicle seeking to enter the cradle, by allowing to approach the vehicle obliquely to the cradle, so that the bow comes into contact with the rear lateral extension and is deflected towards the entrance of the cradle.
L’entrée du véhicule dans le berceau est alors facilitée puisqu’il n’est plus nécessaire d’aligner l’axe longitudinal de le véhicule avec celui du berceau pour pouvoir faire entrer le véhicule dans le berceau.  The entry of the vehicle into the cradle is then facilitated since it is no longer necessary to align the longitudinal axis of the vehicle with that of the cradle to be able to enter the vehicle into the cradle.
Selon des modes de réalisation particuliers, le dispositif de récupération comprend une ou plusieurs des caractéristiques optionnelles suivantes, prises individuellement ou selon toutes les combinaisons techniquement possibles :  According to particular embodiments, the recovery device comprises one or more of the following optional characteristics, taken individually or in any technically possible combination:
- il comprend au moins une extension latérale arrière configurée pour être montée de manière amovible sur le berceau ;  - It comprises at least one rear lateral extension configured to be removably mounted on the cradle;
- il comprend deux extensions latérales arrière configurées pour être montées de manière amovible sur le berceau, chaque extension latérale arrière étant configurée pour être montée sur une partie latérale respective parmi les deux parties latérales délimitant l’entrée du berceau ;  - It comprises two rear lateral extensions configured to be removably mounted on the cradle, each rear lateral extension being configured to be mounted on a respective lateral part from the two lateral parts delimiting the entrance to the cradle;
- il comprend une extension latérale arrière configurée pour être montée de manière amovible sur le berceau, sélectivement sur une partie latérale ou sur l’autre partie latérale parmi les deux parties latérales délimitant l’entrée du berceau ; et  - It includes a rear lateral extension configured to be removably mounted on the cradle, selectively on a lateral part or on the other lateral part from the two lateral parts delimiting the entrance to the cradle; and
- la ou chaque extension latérale arrière présente une longueur, prise suivant un axe longitudinal du berceau, égale ou supérieure à 1/6 de la longueur du berceau prise entre l’entrée et l’extrémité avant du berceau.  - The or each rear lateral extension has a length, taken along a longitudinal axis of the cradle, equal to or greater than 1/6 of the length of the cradle taken between the entrance and the front end of the cradle.
L’invention concerne également un navire équipé d’un dispositif de récupération tel que défini ci-dessus.  The invention also relates to a ship equipped with a recovery device as defined above.
L’invention concerne encore un procédé de récupération d’un véhicule à l’aide d’un dispositif de récupération tel que défini ci-dessus, le véhicule étant piloté pour avancer vers l’entrée du berceau à partir du côté du berceau opposé au côté où est située l’extension latérale arrière et en étant orienté obliquement par rapport au berceau de façon que la proue du véhicule vienne en contact avec l’extension latérale arrière et soit déviée par l’extension latérale arrière vers l’entrée du berceau.  The invention also relates to a method of recovering a vehicle using a recovery device as defined above, the vehicle being driven to advance towards the entrance of the cradle from the side of the cradle opposite the side where the rear side extension is located and being oriented obliquely to the cradle so that the bow of the vehicle comes into contact with the rear side extension and is deflected by the rear side extension towards the entrance of the cradle.

L’invention et ses avantages seront mieux compris à la lecture de la description qui va suivre, donnée uniquement à titre d’exemple non limitatif, et faite en référence au dessin annexé, sur lequel l’unique Figure est une vue schématique de dessus d’un navire muni d’un dispositif de récupération d’un véhicule, le dispositif de récupération étant dans une première configuration.  The invention and its advantages will be better understood on reading the description which follows, given solely by way of nonlimiting example, and made with reference to the appended drawing, in which the single Figure is a schematic view from above of 'A ship fitted with a vehicle recovery device, the recovery device being in a first configuration.
Le navire 2 illustré sur la Figure est équipé d’un dispositif de récupération 4 permettant de récupérer un véhicule 6 pour le remonter sur le navire 2. Le dispositif de récupération est avantageusement utilisable aussi pour la mise à l’eau du véhicule à partir du navire 2.  The ship 2 illustrated in the Figure is equipped with a recovery device 4 making it possible to recover a vehicle 6 for reassembling it on the ship 2. The recovery device is advantageously also usable for launching the vehicle from the ship 2.
Le navire 2 est illustré partiellement sur la Figure, seul un bordé tribord 8 et une partie d’un pont 10 du navire 2 étant visibles. Le navire 2 est par exemple en mouvement vers l’avant suivant une direction d’avancement E.  The ship 2 is partially illustrated in the Figure, only a starboard plating 8 and part of a deck 10 of the ship 2 being visible. The ship 2 is for example moving forward in a direction of advance E.
Le navire 2 est équipé d’un moyen de levage 12 (représenté en traits pointillées sur la Figure) permettant de manutentionner le dispositif de récupération 4 à partir du navire 2.  The vessel 2 is equipped with a lifting means 12 (shown in dotted lines in the Figure) making it possible to handle the recovery device 4 from the vessel 2.
Le moyen de levage 12 est par exemple monté sur le pont 10 du navire 2 en étant basculant autour d’un axe horizontal A entre une position rentrée (non représentée) dans laquelle le moyen de levage 12 permet de manutentionner des charges au-dessus du pont 10 et une position sortie (illustrée en traits pointillés sur la Figure) dans laquelle le moyen de levage 12 déborde à l’extérieur du navire, au-delà du plat-bord, pour monter ou descendre des charges situées à côté du navire 2.  The lifting means 12 is for example mounted on the deck 10 of the ship 2 by being tiltable about a horizontal axis A between a retracted position (not shown) in which the lifting means 12 makes it possible to handle loads above the deck 10 and an extended position (illustrated in dotted lines in the Figure) in which the lifting means 12 overflows outside the ship, beyond the gunwale, to raise or lower loads located next to the ship 2 .
Comme illustré sur la Figure, le moyen de levage 12 est en position sortie et le dispositif de récupération 4 est mis à l’eau à côté du navire 2, à tribord.  As illustrated in the Figure, the lifting means 12 is in the extended position and the recovery device 4 is launched into the water next to the ship 2, to starboard.
Le véhicule 6 est par exemple un engin de surface ou un engin sous-marin, un tel engin sous-marin pouvant aussi flotter et se déplacer à la surface de l’eau, en particulier au cours d’une manœuvre de mise à l’eau ou d’une manœuvre de récupération.  The vehicle 6 is for example a surface craft or an underwater craft, such an underwater craft can also float and move on the surface of the water, in particular during a launching maneuver. water or a recovery maneuver.
Le véhicule 6 est par exemple un drone sans pilote à bord, en particulier un drone de surface sans pilote à bord (ou USV de l’anglais « Unmanned Surface Vessel ») ou un drone sous-marin sans pilote à bord (ou UUV de l’anglais « Unmanned Underwater Vessel » ou encore UAV de l’anglais « Unmanned Autonomous Vehicle »). En variante, le véhicule 6 est un drone de surface avec pilote à bord ou un drone sous- marin avec pilote à bord. The vehicle 6 is for example an unmanned drone on board, in particular a surface unmanned drone on board (or USV for Unmanned Surface Vessel) or an unmanned underwater drone on board (or UUV of English "Unmanned Underwater Vessel ”or UAV from English“ Unmanned Autonomous Vehicle ”). As a variant, the vehicle 6 is a surface drone with pilot on board or an underwater drone with pilot on board.
Le véhicule 6 présente un axe longitudinal B et possède une proue 6A (partie avant du véhicule 6) et une poupe 6B (partie arrière du véhicule 6) espacées le long de cette axe longitudinal B.  The vehicle 6 has a longitudinal axis B and has a bow 6A (front part of the vehicle 6) and a stern 6B (rear part of the vehicle 6) spaced along this longitudinal axis B.
Le véhicule 6 comprend de préférence un système de propulsion 14 assurant la propulsion du véhicule 6. Le système de propulsion 14 comprend par exemple un ou plusieurs moteur(s) et/ou un ou plusieurs propulseur(s).  The vehicle 6 preferably comprises a propulsion system 14 ensuring the propulsion of the vehicle 6. The propulsion system 14 comprises for example one or more engine (s) and / or one or more propellant (s).
Le véhicule 6 comprend de préférence un système de direction 16 permettant de diriger le véhicule 6. Le système de direction 16 comprend par exemple un ou plusieurs gouvernail(s). En varient ou en complément facultatif, le système de direction 16 est configuré pour permettre l’orientation d’au moins une partie du système de propulsion 14, par exemple l’orientation d’un ou plusieurs propulseur(s).  The vehicle 6 preferably comprises a steering system 16 making it possible to steer the vehicle 6. The steering system 16 comprises for example one or more rudder (s). In varying or optional complement, the steering system 16 is configured to allow the orientation of at least part of the propulsion system 14, for example the orientation of one or more propellant (s).
Le dispositif de récupération 4 comprend un berceau 18 configuré pour recevoir le véhicule 6 et pour le supporter.  The recovery device 4 comprises a cradle 18 configured to receive the vehicle 6 and to support it.
Le berceau 18 est flottant. Ainsi, il flotte lorsqu’il est mis à l’eau. Un tel berceau 18 flottant est aussi nommé « cage flottante » ou « dock flottant ».  The cradle 18 is floating. Thus, it floats when it is launched. Such a floating cradle 18 is also called a "floating cage" or "floating dock".
Lorsque le véhicule 6 est reçu dans le berceau 18, le berceau 18 est propre à être manutentionné pour sortir le véhicule 6 de l’eau ou le mettre à l’eau, le véhicule 6 étant porté par le berceau 18.  When the vehicle 6 is received in the cradle 18, the cradle 18 is capable of being handled to remove the vehicle 6 from the water or put it in the water, the vehicle 6 being carried by the cradle 18.
Le berceau 18 s’étend suivant un axe longitudinal C et possède une extrémité avant 18A et une extrémité arrière 18B espacées suivant cet axe longitudinal C du berceau 18.  The cradle 18 extends along a longitudinal axis C and has a front end 18A and a rear end 18B spaced along this longitudinal axis C of the cradle 18.
Le berceau 18 est configuré pour que le véhicule 6 à la surface de l’eau puisse entrer dans le berceau 18 flottant à la surface de l’eau par l’extrémité arrière 18B du berceau 18, i.e. de l’arrière vers l’avant.  The cradle 18 is configured so that the vehicle 6 at the surface of the water can enter the cradle 18 floating on the surface of the water through the rear end 18B of the cradle 18, ie from the rear to the front .
Le berceau 18 est prévu pour recevoir le véhicule 6 avec l’axe longitudinal B du véhicule 6 sensiblement aligné avec l’axe longitudinal C du berceau 18, la proue 6A du véhicule 6 étant adjacente à l’extrémité avant 18A du berceau 18 et la poupe 6B du véhicule 6 étant adjacente à l’extrémité arrière 18B du berceau 18.  The cradle 18 is designed to receive the vehicle 6 with the longitudinal axis B of the vehicle 6 substantially aligned with the longitudinal axis C of the cradle 18, the bow 6A of the vehicle 6 being adjacent to the front end 18A of the cradle 18 and the stern 6B of the vehicle 6 being adjacent to the rear end 18B of the cradle 18.
Le berceau 18 possède à son extrémité arrière 18B une entrée 20 permettant au véhicule 6 d’entrer dans le berceau 18 lorsque le berceau 18 flotte sur l’eau.  The cradle 18 has at its rear end 18B an inlet 20 allowing the vehicle 6 to enter the cradle 18 when the cradle 18 floats on water.
Le berceau 18 possède deux parties latérales 22 délimitant entre elles l’entrée 20 du berceau 18. Les deux parties latérales 22 permettent notamment de guider latéralement le véhicule 6 lors de son entrée dans le berceau 18. Le berceau 18 est configuré ou configurable de manière qu’il possède une extension latérale arrière 24 s’étendant longitudinalement vers l’arrière à partir d’une seule des parties latérales 22 délimitant l’entrée 20. The cradle 18 has two lateral parts 22 delimiting between them the entrance 20 of the cradle 18. The two lateral parts 22 make it possible in particular to guide the vehicle 6 laterally when it enters the cradle 18. The cradle 18 is configured or configurable so that it has a rear lateral extension 24 extending longitudinally towards the rear from one of the lateral parts 22 delimiting the entry 20.
L’extension latérale arrière 24 s’étend vers l’arrière à partir de l’une des parties latérales 22 sensiblement suivant l’axe longitudinal C du berceau 18.  The rear lateral extension 24 extends towards the rear from one of the lateral parts 22 substantially along the longitudinal axis C of the cradle 18.
Une partie latérale 22 est munie de l’extension latérale arrière 24, l’autre partie latérale 22 étant dépourvue de telle extension latérale arrière.  A side part 22 is provided with the rear side extension 24, the other side part 22 being devoid of such rear side extension.
L’extension latérale arrière 24 s’étend longitudinalement vers l’arrière au-delà de l’entrée 20.  The rear lateral extension 24 extends longitudinally towards the rear beyond the entrance 20.
L’extension latérale arrière 24 prolonge la partie latérale 22 sur laquelle elle est disposée vers l’arrière du berceau 18, à partir de l’entrée 20.  The rear lateral extension 24 extends the lateral part 22 on which it is arranged towards the rear of the cradle 18, from the entrance 20.
Comme illustré sur la Figure, le berceau 18 muni de l’extension latérale arrière 24 présente en vue de dessus une forme dissymétrique par rapport à un plan médian vertical passant par l’axe longitudinal C du berceau 18, cette forme dissymétrique étant conférée par l’extension latérale arrière 24.  As illustrated in the Figure, the cradle 18 provided with the rear lateral extension 24 has a top view of an asymmetrical shape with respect to a vertical median plane passing through the longitudinal axis C of the cradle 18, this asymmetrical shape being imparted by the rear extension 24.
Le côté du berceau 18 dont la partie latérale 22 est munie de l’extension latérale arrière 24 s’étend plus loin vers l’arrière que le côté du berceau 18 dépourvu d’extension latérale arrière.  The side of the cradle 18, the side portion 22 of which is provided with the rear side extension 24 extends farther back than the side of the cradle 18 without the rear side extension.
Les parties latérales 22 du berceau 18 s’étendent de manière symétrique de part et d’autre du plan médian. En particulier, les parties latérales 22 possèdent la même longueur, prise suivant l’axe longitudinal C du berceau 18.  The lateral parts 22 of the cradle 18 extend symmetrically on either side of the median plane. In particular, the lateral parts 22 have the same length, taken along the longitudinal axis C of the cradle 18.
La dissymétrie du berceau 18 est conférée par l’extension latérale arrière 24 qui prolonge l’une des parties latérales 22 vers l’arrière du berceau 18, l’autre partie latérale 22 n’étant pas prolongée.  The asymmetry of the cradle 18 is imparted by the rear lateral extension 24 which extends one of the lateral parts 22 towards the rear of the cradle 18, the other lateral part 22 not being extended.
L’extension latérale arrière 24 est de préférence d’une longueur, prise suivant l’axe longitudinal C du berceau 18, supérieure ou égale à 1/6 de la longueur de la partie latérale 22 du berceau 18. La longueur de la partie latérale 22 du berceau 18 est prise suivant l’axe longitudinal C du berceau 18, entre l’entrée 20 et l’extrémité avant 18A du berceau 18.  The rear lateral extension 24 is preferably of a length, taken along the longitudinal axis C of the cradle 18, greater than or equal to 1/6 of the length of the lateral part 22 of the cradle 18. The length of the lateral part 22 of the cradle 18 is taken along the longitudinal axis C of the cradle 18, between the inlet 20 and the front end 18A of the cradle 18.
Le berceau 18 est avantageusement configuré pour empêcher le véhicule 6 de sortir à l’extrémité avant 18A du berceau 18. Pour ce faire, par exemple, le berceau 18 se rétrécit vers son extrémité avant 18A et/ou est fermé à son extrémité avant 18A.  The cradle 18 is advantageously configured to prevent the vehicle 6 from going out at the front end 18A of the cradle 18. To do this, for example, the cradle 18 narrows towards its front end 18A and / or is closed at its front end 18A .
Avantageusement, le berceau 18 est caréné et possède une coque s’étendant suivant l’axe longitudinal C du berceau 18. Une telle coque diminue la résistance à l’avancement et le sillage du berceau 18 lorsque le berceau 18 est mis à l’eau sur le côté du navire 2 qui avance sur l’eau. Advantageously, the cradle 18 is faired and has a shell extending along the longitudinal axis C of the cradle 18. Such a shell reduces the resistance to the advancement and wake of the cradle 18 when the cradle 18 is launched on the side of the ship 2 which advances on the water.
Tel qu’illustré sur la Figure, l’extension latérale arrière 24 est prévue sur la partie latérale 22 bâbord du berceau 18, i.e. la partie latérale 22 située sur la gauche du berceau 18 en regardant de vers l’avant du berceau 18, et le berceau 18 est mis à l’eau sur le côté tribord du navire 2. Ainsi, l’extension arrière 24, qui est située sur le côté bâbord du berceau 18, est située sur la partie latérale 22 de l’entrée 20 du berceau 18 qui est adjacente au navire 2.  As illustrated in the Figure, the rear lateral extension 24 is provided on the side part 22 port of the cradle 18, ie the side part 22 located on the left of the cradle 18 looking towards the front of the cradle 18, and the cradle 18 is launched on the starboard side of the ship 2. Thus, the rear extension 24, which is located on the port side of the cradle 18, is located on the lateral part 22 of the inlet 20 of the cradle 18 which is adjacent to ship 2.
En fonctionnement, pour la récupération du véhicule 6, le berceau 18 est mis à l’eau à l’aide du moyen de levage 12 à côté du navire 2, ici sur le côté tribord. Le berceau 18 est maintenu sur le côté, par exemple à l’aide du moyen de levage 12 et/ou de câbles reliant par exemple l’extrémité avant du berceau 18 au navire 2.  In operation, for the recovery of the vehicle 6, the cradle 18 is launched using the lifting means 12 next to the ship 2, here on the starboard side. The cradle 18 is held on the side, for example using the lifting means 12 and / or cables connecting for example the front end of the cradle 18 to the ship 2.
Le berceau 18 suit la route du navire 2. Le véhicule 6 est piloté vers l’entrée 20 du berceau 18 en s’approchant par tribord, en suivant une route convergente avec celle du berceau 18, i.e. en avançant suivant une direction de déplacement faisant un angle non nul avec celle berceau 18 et en se rapprochant du navire 2. Sur la Figure, l’axe longitudinal B du véhicule 6 fait un angle a non nul avec l’axe longitudinal C du berceau 18. En particulier, le système de propulsion 14 et le système de direction 16 du véhicule 6 sont pilotés pour suivre une telle route vers le berceau 18 mis à l’eau.  The cradle 18 follows the course of the ship 2. The vehicle 6 is driven towards the entrance 20 of the cradle 18 while approaching on the starboard side, following a route converging with that of the cradle 18, ie by advancing in a direction of movement a non-zero angle with that of the cradle 18 and approaching the ship 2. In the Figure, the longitudinal axis B of the vehicle 6 forms a non-zero angle a with the longitudinal axis C of the cradle 18. In particular, the system of propulsion 14 and the steering system 16 of the vehicle 6 are controlled to follow such a route to the cradle 18 launched.
Le véhicule 6 est ainsi piloté de manière à arriver par l’arrière et obliquement par rapport au berceau 18, du côté de l’entrée 20 du berceau opposé à l’extension latérale arrière 24, de manière que sa proue 6A vienne en contact avec l’extension latérale arrière 24 du berceau 18. L’extension latérale arrière 24 guide alors le véhicule 6 en déviant la proue 6A du véhicule 6 vers l’entrée 20 du berceau 18. L’extension latérale arrière 24 du berceau 18 est donc configurée pour guider la proue 6A du véhicule 6 vers l’entrée 20 du berceau 18.  The vehicle 6 is thus controlled so as to arrive from the rear and obliquely with respect to the cradle 18, on the side of the inlet 20 of the cradle opposite the rear lateral extension 24, so that its bow 6A comes into contact with the rear lateral extension 24 of the cradle 18. The rear lateral extension 24 then guides the vehicle 6 by deflecting the bow 6A of the vehicle 6 towards the inlet 20 of the cradle 18. The rear lateral extension 24 of the cradle 18 is therefore configured to guide the bow 6A of the vehicle 6 towards the entrance 20 of the cradle 18.
Une fois le véhicule 6 reçu à l’intérieur du berceau 18, le berceau 18 portant le véhicule 6 est soulevé hors de l’eau et ramené sur le navire 2, en particulier sur le pont 10, à l’aide du moyen de levage 12.  Once the vehicle 6 has been received inside the cradle 18, the cradle 18 carrying the vehicle 6 is lifted out of the water and brought back to the ship 2, in particular on the deck 10, using the lifting means 12.
Ainsi, la présence de l’extension latérale arrière 24 facilite l’entrée du véhicule 6 dans le berceau 18 lors de la récupération du véhicule 6.  Thus, the presence of the rear lateral extension 24 facilitates the entry of the vehicle 6 into the cradle 18 during the recovery of the vehicle 6.
Cette entrée du véhicule 6 peut en effet être rendue difficile pour la houle qui entraîne des mouvements relatifs du navire 2, du berceau 18 et du véhicule 6 qui sont difficilement prévisibles et maîtrisables, notamment lorsque la mer est dans un état formé. Par ailleurs, pour récupérer le véhicule 6 sans interrompre l’avancée du navire 2, il est souhaitable de récupérer le véhicule 6 pendant que le navire 2 avance. Or, lorsqu’il avance, le navire 2 crée une succion qui tend à attirer vers le navire 2 tout objet flottant situé à proximité du navire 2 sur le côté de celui-ci. Ainsi, le véhicule 6 s’approchant par le côté du navire 2 en mouvement tend à être attiré vers le navire 2. L’extension latérale arrière 24 située sur le berceau 18 du côté du navire 2 permet de guider le véhicule 6 vers l’entrée 22 tout en l’empêchant d’aller vers le navire 2. This entry of the vehicle 6 can indeed be made difficult for the swell which causes relative movements of the ship 2, of the cradle 18 and of the vehicle 6 which are difficult to predict and to control, especially when the sea is in a formed state. Furthermore, to recover the vehicle 6 without interrupting the advance of the ship 2, it is desirable to recover the vehicle 6 while the ship 2 is advancing. However, when it advances, the ship 2 creates a suction which tends to attract to the ship 2 any floating object located near the ship 2 on the side thereof. Thus, the vehicle 6 approaching from the side of the moving ship 2 tends to be attracted towards the ship 2. The rear lateral extension 24 located on the cradle 18 on the side of the ship 2 makes it possible to guide the vehicle 6 towards the entry 22 while preventing it from going to ship 2.
Enfin, lorsqu’il avance, le navire 2 crée un sillage qui prend la forme d’un cône de vagues transverses et divergentes (sillage communément nommé sillage de « Kelvin »), qui tend à perturber tout objet flottant situé à proximité du navire 2. L’extension latérale arrière 24 située sur le berceau 18 du côté du navire 2 permet d’adopter une route d’approche oblique du véhicule 6 par rapport au navire 2, afin d’éviter les zones de sillage perturbatrices crées par le navire 2.  Finally, when it advances, the ship 2 creates a wake which takes the form of a cone of transverse and divergent waves (wake commonly known as the wake of "Kelvin"), which tends to disturb any floating object located near the ship 2 The rear lateral extension 24 located on the cradle 18 on the side of the ship 2 makes it possible to adopt an oblique approach route of the vehicle 6 relative to the ship 2, in order to avoid the disturbing wake zones created by the ship 2. .
Sur la Figure, l’extension latérale arrière 24 est prévue sur la partie latérale 22 située du côté bâbord du berceau 18 pour effectuer une récupération du véhicule 6 sur le côté tribord du navire 2.  In the Figure, the rear lateral extension 24 is provided on the lateral part 22 located on the port side of the cradle 18 to recover the vehicle 6 on the starboard side of the ship 2.
Dans un autre exemple de réalisation, et comme illustré en traits mixtes sur la Figure, l’extension latérale arrière 24 du berceau 18 est prévue sur la partie latérale 22 située sur le côté tribord du berceau 18, le berceau 18 étant alors dépourvu d’extension latérale arrière sur la partie latérale 22 située du côté bâbord du berceau 18, par exemple pour effectuer une récupération du véhicule 6 sur le côté bâbord du navire 2.  In another exemplary embodiment, and as illustrated in phantom in the Figure, the rear lateral extension 24 of the cradle 18 is provided on the lateral part 22 located on the starboard side of the cradle 18, the cradle 18 then being devoid of aft lateral extension on the lateral part 22 located on the port side of the cradle 18, for example to recover the vehicle 6 on the port side of the ship 2.
Dans un exemple de réalisation, un berceau 18 est muni d’une extension latérale arrière 24 montée inamovible sur l’une de la partie latérale 22 située du côté bâbord du berceau 18 et de la partie latérale 22 située du côté tribord du berceau 18, la partie latérale 22 située de l’autre côté du berceau 18 étant dépourvue d’extension latérale arrière.  In an exemplary embodiment, a cradle 18 is provided with a rear lateral extension 24 mounted irremovable on one of the lateral part 22 situated on the port side of the cradle 18 and of the lateral part 22 situated on the starboard side of the cradle 18, the lateral part 22 situated on the other side of the cradle 18 being devoid of rear lateral extension.
Dans un premier exemple de réalisation pouvant être illustré par la Figure, le berceau 18 est muni d’une extension latérale arrière 24 montée inamovible sur la partie latérale 22 située du côté bâbord du berceau 18, la partie latérale 22 située du côté tribord du berceau 18 étant dépourvue d’extension latérale arrière.  In a first exemplary embodiment which can be illustrated by the Figure, the cradle 18 is provided with a rear lateral extension 24 mounted on the side portion 22 located on the port side of the cradle 18, the side portion 22 located on the starboard side of the cradle 18 having no rear lateral extension.
Dans un deuxième exemple de réalisation pouvant être illustré par les traits mixte sur la Figure, le berceau 18 est muni d’une extension latérale arrière 24 montée inamovible sur la partie latérale 22 située du côté tribord du berceau 18, la partie latérale 22 située du côté bâbord du berceau 18 étant dépourvue d’extension latérale arrière. Dans un autre exemple de réalisation, le berceau 18 est muni d’au moins une extension latérale arrière 24 montée amovible sur le berceau 18. L’extension latérale arrière 24 amovible peut être démontée et retirée du berceau 18. In a second exemplary embodiment which can be illustrated by the dashed lines in the Figure, the cradle 18 is provided with a rear lateral extension 24 mounted irremovable on the side part 22 located on the starboard side of the cradle 18, the side part 22 located at the port side of the cradle 18 being devoid of aft lateral extension. In another exemplary embodiment, the cradle 18 is provided with at least one rear lateral extension 24 removably mounted on the cradle 18. The removable rear lateral extension 24 can be disassembled and removed from the cradle 18.
Le berceau 18 est alors configurable, chaque extension latérale arrière 24 pouvant être montée sur le berceau 18 ou démontée du berceau 18.  The cradle 18 can then be configured, each rear lateral extension 24 being able to be mounted on the cradle 18 or disassembled from the cradle 18.
Dans un exemple de réalisation, le berceau 18 possède deux extensions latérales arrière 24 montées amovibles sur le berceau 18, à savoir une extension latérale arrière 24 bâbord et une extension latérale arrière 24 tribord, le berceau 18 étant configurable par retrait de l’une des extensions latérales arrières 24 et maintien de l’autre sur le berceau 18, par exemple pour la récupération d’un véhicule 6 d’un côté ou de l’autre d’un navire 2 qui avance.  In an exemplary embodiment, the cradle 18 has two rear lateral extensions 24 removably mounted on the cradle 18, namely a rear lateral extension 24 on the port side and a rear lateral extension 24 on the starboard side, the cradle 18 being configurable by removing one of the rear side extensions 24 and holding the other on the cradle 18, for example for the recovery of a vehicle 6 on one side or the other of a ship 2 which is advancing.
Dans un exemple de réalisation, le berceau 18 possède une extension latérale arrière 24 configurée pour être montée de manière amovible, sélectivement sur la partie latérale 22 située du côté bâbord du berceau 18 ou sur la partie latérale 22 située du côté tribord du berceau 18.  In an exemplary embodiment, the cradle 18 has a rear lateral extension 24 configured to be removably mounted, selectively on the lateral part 22 situated on the port side of the cradle 18 or on the lateral part 22 situated on the starboard side of the cradle 18.
Le dispositif de récupération 4 a été décrit ci-dessus dans une utilisation sur un navire 2, en particulier pour récupérer un véhicule 6 pendant que le navire 2 est en mouvement vers l’avant.  The recovery device 4 has been described above in use on a ship 2, in particular for recovering a vehicle 6 while the ship 2 is moving forward.
Le dispositif de récupération 4 est utilisable pendant que le navire 2 n’est pas en mouvement.  The recovery device 4 can be used while the vessel 2 is not in motion.
La prévision de l’extension latérale arrière 24 facilite l’entrée du véhicule 6 y compris lorsque le berceau 18 est immobile, en permettant l’entrée du véhicule 6 dans le berceau 18 avec un angle non nul ente l’axe longitudinal B du véhicule 6 et l’axe longitudinal C du berceau 18.  The provision of the rear lateral extension 24 facilitates the entry of the vehicle 6 even when the cradle 18 is stationary, by allowing the entry of the vehicle 6 into the cradle 18 with a non-zero angle between the longitudinal axis B of the vehicle 6 and the longitudinal axis C of the cradle 18.
Le dispositif de récupération 4 est également utilisable sur une plateforme flottante immobile ou une installation fixe fixée au sol ou au fond marin.  The recovery device 4 can also be used on a stationary floating platform or a fixed installation fixed to the ground or to the seabed.
Le dispositif de récupération 4 est utilisable également pour la mise à l’eau d’un véhicule 6, par exemple à partir d’un navire, d’une plateforme flottante ou d’une installation fixe.  The recovery device 4 can also be used for launching a vehicle 6, for example from a ship, a floating platform or a fixed installation.
Pour ce faire, le véhicule 6 étant porté par le berceau 18 monté à bord du navire ou de la plateforme flottante ou sur l’installation fixe, le berceau 18 est mis à l’eau et le véhicule 6 est piloté pour sortir du berceau 18, en marche arrière et par l’entrée 20 du berceau 18.  To do this, the vehicle 6 being carried by the cradle 18 mounted on board the ship or the floating platform or on the fixed installation, the cradle 18 is launched and the vehicle 6 is driven to exit the cradle 18 , in reverse and through the entrance 20 of the cradle 18.
Une telle opération peut être effectuée à partir d’un navire en mouvement. Ainsi, le dispositif de récupération constitue un dispositif de récupération et/ou de mise à l’eau d’un véhicule.  Such an operation can be carried out from a moving ship. Thus, the recovery device constitutes a device for recovering and / or launching a vehicle.
