Description

La présente invention concerne un système de manutention comprenant :

  • un portique de levage monté mobile sur une plateforme navale,
  • un support flottant (également appelé dock) de mise à l'eau et/ou de récupération d'un drone de surface propre à loger le drone de surface, le support flottant comprenant en partie basse un berceau de réception du drone de surface et en partie haute un palonnier de levage propre à être attaché au portique de levage.
The present invention relates to a handling system comprising:
  • a lifting gantry mounted mobile on a naval platform,
  • a floating support (also called dock) for launching and / or recovering a surface drone suitable for housing the surface drone, the floating support comprising in the lower part a cradle for receiving the surface drone and in upper part a lifting beam suitable for being attached to the lifting frame.

La présente invention concerne également un support flottant de mise à l'eau et/ou de récupération du drone de surface propre à loger le drone de surface, le support flottant comprenant en partie basse un berceau de réception du drone de surface et en partie haute un palonnier de levage propre à être attaché à un portique de levage monté mobile sur une plateforme navale.The present invention also relates to a floating support for launching and / or recovering the surface drone suitable for housing the surface drone, the floating support comprising in the lower part a cradle for receiving the surface drone and in the upper part a lifting beam suitable for being attached to a lifting gantry mounted mobile on a naval platform.

La présente invention concerne également une plateforme navale comprenant un système de manutention du type précité.The present invention also relates to a naval platform comprising a handling system of the aforementioned type.

La présente invention concerne également un procédé de manutention mis en œuvre au moyen du système de manutention précité.The present invention also relates to a handling method implemented by means of the aforementioned handling system.

Pour la mise à l'eau et/ou la récupération de drone marin de surface (USV de l'anglais « Unmanned Surface Vehicle ») par le bordé d'une plateforme navale, des solutions basées ont été développées. Parmi ces solutions, une solution basée sur l'utilisation d'un support flottant tel que décrit dans la demande WO 97/39940 est utilisée pour loger le drone marin de surface lors de ces opérations.For the launch and / or recovery of a surface marine drone (USV from the English “ Unmanned Surface Vehicle ”) by the shell of a naval platform, based solutions have been developed. Among these solutions, a solution based on the use of a floating support as described in the application WO 97/39940 is used to house the surface marine drone during these operations.

Un tel support flottant présente, pour ce faire, deux parties solidaires de manière permanente, à savoir une partie basse formant un logement ou berceau de réception dont les caractéristiques sont telles qu'elles permettent que le drone marin de surface et le support flottant présentent des conditions de flottaisons et de tenue à la mer sensiblement identiques, et une partie haute formant palonnier de levage propre être levée, par exemple au moyen d'élingue(s) par un portique de levage (i.e. une grue à portique ou encore un bossoir).To do this, such a floating support has two permanently integral parts, namely a lower part forming a housing or receiving cradle whose characteristics are such that they allow the surface marine drone and the floating support to have substantially identical flotation and sea-keeping conditions, and an upper part forming a clean lifting beam be lifted, for example by means of a sling (s) by a lifting gantry (ie a gantry crane or even a davit) .

Toutefois, le support flottant selon la demande WO 97/39940 présente l'inconvénient d'empêcher la manutention de charges utiles à charger/décharger sur le drone marin de surface. De telles charges utiles sont notamment volumineuses et lourdes et correspondent par exemple à un sonar remorqué, un robot sous-marin autonome (AUV de l'anglais « Autonomous Underwater Vehicle »), un véhicule téléguidé (ROV de l'anglais « Remotely Operated Vehicle »), et leur manutention pour chargement/déchargement sur le drone de surface entre en interférence avec la partie haute formant palonnier de levage du support flottant selon la demande WO 97/39940 .However, the floating support according to demand WO 97/39940 has the drawback of preventing the handling of payloads to be loaded / unloaded on the surface marine drone. Such payloads are in particular bulky and heavy and correspond for example to a towed sonar, an autonomous underwater robot (AUV from the English " Autonomous Underwater Vehicle "), a remote-controlled vehicle (ROV from the English " Remotely Operated Vehicle "), and their handling for loading / unloading on the surface drone interferes with the upper part forming lifting beam of the floating support according to demand WO 97/39940 .

Un des buts de l'invention est donc de résoudre ce problème.One of the aims of the invention is therefore to solve this problem.

A cet effet l'invention a pour objet un système de manutention comprenant:

  • un portique de levage monté mobile sur une plateforme navale,
  • un support flottant de mise à l'eau et/ou de récupération d'un drone de surface propre à loger le drone de surface, le support flottant comprenant en partie basse un berceau de réception du drone de surface et en partie haute un palonnier de levage propre à être attaché au portique de levage, le palonnier de levage étant détachable du berceau.
To this end the invention relates to a handling system comprising:
  • a lifting gantry mounted mobile on a naval platform,
  • a floating support for launching and / or recovering a surface drone suitable for housing the surface drone, the floating support comprising in the lower part a cradle for receiving the surface drone and in the upper part a lifting beam for lifting adapted to be attached to the lifting frame, the lifting beam being detachable from the cradle.

Par « détachable » on entend que le palonnier et le berceau, forment un tout à savoir le support flottant, et que le palonnier et le berceau sont séparables, isolables l'un de l'autre, sans aucune détérioration, au moment de l'établissement de la liaison, ou au moment de la séparation, de ces deux éléments. En d'autres termes, le palonnier est fixé de manière amovible sur le berceau.By “detachable” is meant that the lifter and the cradle form a whole, namely the floating support, and that the lifter and the cradle are separable, isolable from each other, without any deterioration, at the time of establishment of the connection, or at the time of separation, of these two elements. In other words, the lifter is removably attached to the cradle.

Ainsi le pont du drone de surface est accessible et son chargement/déchargement est facilité et possible à mettre en œuvre par un seul opérateur humain. En effet, l'ensemble formé d'une part par le portique de levage et d'autre part par le palonnier détaché du support flottant mais par ailleurs attaché au portique de levage, est propre à être débordé et n'interfère plus avec toute opération de manutention visant à charger/décharger le pont du drone de surface. En d'autres termes, l'ensemble portique-palonnier, lorsqu'il est débordé en dehors de la plateforme alors que le support flottant logeant le drone de surface reste sur la plateforme, libère l'ensemble du volume vertical localisé au-dessus du pont du drone de surface ce qui le rend accessible et facilite les opérations de manutention notamment au moyen d'un ou de plusieurs pont(s) roulant(s) fixé(s) au plafond d'un hangar de manutention localisé sur le pont de la plateforme navale.Thus the deck of the surface drone is accessible and its loading / unloading is facilitated and possible to be implemented by a single human operator. Indeed, the assembly formed on the one hand by the lifting gantry and on the other hand by the lifter detached from the floating support but also attached to the lifting gantry, is suitable for being overflowed and no longer interferes with any operation handling aimed at loading / unloading the deck of the surface drone. In other words, the gantry-lifter assembly, when it is overflowed outside the platform while the floating support housing the surface drone remains on the platform, releases the entire vertical volume located above the deck of the surface drone which makes it accessible and facilitates handling operations in particular by means of one or more traveling bridge (s) fixed to the ceiling of a handling hangar located on the the naval platform.

La plateforme navale 12 de la figure 1 est représentée en phase de navigation sur l'eau 14 et comprend, à bâbord comme à tribord, un portique de levage 16 monté mobile sur la plateforme navale 12 entre une position à bord telle qu'illustrée par le portique de levage 16 à bâbord, et une position débordée telle qu'illustrée par le portique de levage 16 à tribord.The naval platform 12 of the figure 1 is shown in the navigation phase on the water 14 and comprises, on the port and starboard sides, a lifting gantry 16 mounted mobile on the naval platform 12 between a position on board as illustrated by the lifting gantry 16 on the port side, and an overflowed position as illustrated by the lifting gantry 16 to starboard.

En particulier, le portique de levage 16 est utilisé pour la mise à l'eau et/ou la récupération d'un support flottant (également appelé dock flottant) comprenant une partie basse formant berceau de réception 18 d'un drone de surface 20. Le berceau de réception 18 comprend notamment des montants 21 solidarisables à la partie haute du support flottant correspondant à un palonnier 22 de levage. Le palonnier de levage 22 est propre à être attaché, au moyen par exemple d'élingue(s), au portique de levage 16.In particular, the lifting gantry 16 is used for launching and / or recovering a floating support (also called floating dock) comprising a lower part forming a cradle 18 for receiving a surface drone 20. The receiving cradle 18 comprises in particular uprights 21 which can be secured to the upper part of the floating support corresponding to a lifting beam 22 for lifting. The lifting beam 22 is suitable for being attached, for example by means of a sling (s), to the lifting gantry 16.

Le portique de levage 16 se déplace de la position à bord à la position débordée par exemple par rotation au moyen de vérins hydrauliques 24. De tels vérins hydrauliques 24 sont par exemple commandés à distance par un opérateur utilisant un système de contrôle centralisé non représenté sur la figure 1.The lifting gantry 16 moves from the on-board position to the overflowed position, for example by rotation by means of hydraulic cylinders 24. Such hydraulic cylinders 24 are for example remotely controlled by an operator using a centralized control system not shown in the figure 1 .

Sur la figure 2, le système de manutention à tribord de la plateforme navale 12 selon la présente invention formé par le portique de levage et par le support flottant comprenant en partie basse le berceau de réception 18 du drone de surface 20 et en partie haute le palonnier de levage 22 est représenté en position de chargement d'une charge utile 26.On the figure 2 , the handling system to starboard of the naval platform 12 according to the present invention formed by the lifting gantry and by the floating support comprising in the lower part the receiving cradle 18 of the surface drone 20 and in the upper part the lifting beam 22 is shown in the loading position of a payload 26.

Dans cette position de chargement du système de manutention, le palonnier de levage 22, est à la fois solidarisé au portique de levage 16 et détaché des montants 21 du berceau de réception 18, et l'ensemble formé par le portique de levage 16 et par le palonnier 22 est débordé à l'extérieur de la plateforme navale 12, ici à tribord, alors que le reste du support flottant, à savoir le berceau de réception 18 logeant le drone de surface 20, reste sur la plateforme navale 12 pour chargement/déchargement de la charge utile 26, par exemple au moyen d'un outil de levage 28 (e.g. une grue).In this loading position of the handling system, the lifting beam 22, is both secured to the lifting gantry 16 and detached from the uprights 21 of the receiving cradle 18, and the assembly formed by the lifting gantry 16 and by the lifter 22 is overflowed outside the naval platform 12, here to starboard, while the rest of the floating support, namely the receiving cradle 18 housing the surface drone 20, remains on the naval platform 12 for loading / unloading of the payload 26, for example by means of a lifting tool 28 (eg a crane).

Sur la figure 3, un opérateur O1 commande le vérin hydraulique 24 qui actionne le déplacement du portique de levage 16 pour venir en position à bord de la plateforme navale 12 afin de ramener le support flottant logeant le drone de surface 20 à bord de la plateforme navale 12 pour procéder par la suite au chargement de la charge utile 26 sur le pont du drone de surface 20 notamment au moyen d'un outil de chargement 28 correspondant à un pont roulant suspendu au plafond d'un hangar non représenté.On the figure 3 , an operator O 1 controls the hydraulic cylinder 24 which actuates the movement of the lifting gantry 16 to come into position on board the naval platform 12 in order to bring the floating support housing the surface drone 20 on board the naval platform 12 for subsequently loading the payload 26 on the deck of the surface drone 20 in particular by means of a loading tool 28 corresponding to an overhead crane suspended from the ceiling of a hangar not shown.

Dans cette position préalable à toute manutention de la charge utile 26, le palonnier 22 est à la fois solidarisé d'une part au portique de levage 16 et au berceau 18 de réception du drone de surface 20.In this position prior to any handling of the payload 26, the lifter 22 is both secured on the one hand to the lifting gantry 16 and to the cradle 18 for receiving the surface drone 20.

En particulier, sur la figure 3, sont représentés deux points de fixation 30A et 30B des deux parties détachables l'une de l'autre du support flottant, à savoir la partie haute correspondant au palonnier 22 d'une part, et la partie basse correspondant au berceau 18 d'autre part.In particular, on the figure 3 , two attachment points 30 A and 30 B are shown of the two parts detachable from each other of the floating support, namely the upper part corresponding to the lifting beam 22 on the one hand, and the lower part corresponding to the cradle 18 d 'somewhere else.

Selon un aspect optionnel le portique 16 et le palonnier de levage 22 sont solidarisés par au moins une liaison rigide propre à stabiliser (i.e. en évitant un balancement) le palonnier 22 en position débordée, la liaison rigide étant formée au moins d'un vérin 32 et d'un câble 34.According to an optional aspect, the gantry 16 and the lifting beam 22 are secured by at least one rigid connection capable of stabilizing (ie by avoiding rocking) the lifting beam 22 in the overflowed position, the rigid connection being formed at least of a jack 32 and a cable 34.

Sur la figure 4, le palonnier 22 du support flottant est propre à être détaché du berceau 18 manuellement par un opérateur O2 chargé des opérations de chargement déchargement, et ce tout en restant attaché au portique de levage 16.On the figure 4 , the lifter 22 of the floating support is capable of being detached from the cradle 18 manually by an operator O 2 responsible for loading and unloading operations, while remaining attached to the lifting gantry 16.

Pour ce faire, au niveau de chacun des deux points de fixation 30A et 30B le berceau 18 comprend un élément de verrouillage/déverrouillage (non représenté) du palonnier de levage 22. En particulier, l'élément de verrouillage/déverrouillage est un élément de boulonnage/déboulonnage dont la manipulation manuelle est aisée et rapide.To do this, at each of the two fixing points 30 A and 30 B, the cradle 18 comprises a locking / unlocking element (not shown) of the lifting beam 22. In particular, the locking / unlocking element is a bolting / unbolting element whose manual manipulation is easy and fast.

Par ailleurs, selon une variante non représentée, le support flottant comprend au moins un élément de centrage (e.g. une goupille) associé à chaque élément de verrouillage/déverrouillage.Furthermore, according to a variant not shown, the floating support comprises at least one centering element (e.g. a pin) associated with each locking / unlocking element.

Une telle association permet de détacher/rattacher rapidement et aisément manuellement le palonnier 22 et le support flottant, le palonnier restant par ailleurs solidarisé au portique de levage 16.Such an association makes it possible to quickly and easily detach / reattach the lifter 22 and the floating support, the lifter also remaining secured to the lifting gantry 16.

Sur la figure 5, le portique de levage 16 solidarisé seulement au palonnier 22 est débordé à l'extérieur de la plateforme navale 12 alors que le berceau 18 du support flottant reste à bord. Le pont du drone de surface 20 logé sur le berceau 18 est alors accessible par l'outil de manutention 28 de charge utile 26, toute interférence entre le palonnier 22 et/ou le portique 16 dans la position de la figure 3 étant supprimée.On the figure 5 , the lifting gantry 16 secured only to the lifter 22 is overflowed outside the naval platform 12 while the cradle 18 of the floating support remains on board. The deck of the surface drone 20 housed on the cradle 18 is then accessible by the payload handling tool 28 26, any interference between the lifter 22 and / or the gantry 16 in the position of the figure 3 being deleted.

Autrement dit l'utilisation du portique de levage 16 est enrichie d'une fonction supplémentaire à celle de mise à l'eau et de récupération à savoir une fonction de dégagement du pont du drone de surface 20.In other words, the use of the lifting gantry 16 is enriched with an additional function to that of launching and recovery, namely a function of clearing the deck of the surface drone 20.

De plus, le volume vertical ainsi libéré permet des opérations de manutention verticales, notamment lorsque l'outil de manutention 28 est un pont roulant suspendu au plafond d'un hangar. De telles opérations de manutention verticale permettent notamment d'éviter tout contact (voire détérioration), avec des évents verticaux disposés sur le pont du drone de surface 20 en passant par-dessus la charge utile 26.In addition, the vertical volume thus freed allows vertical handling operations, in particular when the handling tool 28 is an overhead crane suspended from the ceiling of a hangar. Such vertical handling operations make it possible in particular to avoid any contact (or even deterioration), with vertical vents placed on the deck of the surface drone 20 passing over the payload 26.

Sur la figure 6, la charge utile 26 est placée de manière effective sur le pont du drone de surface 20, notamment après avoir passé des évents verticaux du drone de surface 20, la mission de l'opérateur O2 est alors terminée.On the figure 6 , the payload 26 is effectively placed on the deck of the surface drone 20, in particular after having passed vertical vents of the surface drone 20, the mission of the operator O 2 is then completed.

Sur la figure 7, l'ensemble formé par le portique de levage 16 et par le palonnier 22 sont en position à bord de manière à ce que le palonnier 22 soit rattaché aux montants 21 du berceau 18 du support flottant au niveau des points de fixation 30A et 30B.On the figure 7 , the assembly formed by the lifting gantry 16 and by the spreader 22 are in position on board so that the spreader 22 is attached to the uprights 21 of the cradle 18 of the floating support at the fixing points 30 A and 30 B.

Sur la figure 8, le rattachement au berceau 18 de l'ensemble formé par le portique de levage 16 et par le palonnier 22 au niveau des points de fixation 30A et 30B par verrouillage (par exemple boulonnage) de l'élément de verrouillage/déverrouillage (non représenté) est effectif.On the figure 8 , the attachment to the cradle 18 of the assembly formed by the lifting gantry 16 and by the lifting beam 22 at the fixing points 30 A and 30 B by locking (for example bolting) of the locking / unlocking element (not shown) is effective.

Sur la figure 9, le portique de levage 16 du système de manutention selon l'invention, propre à être actionné par l'opérateur O1, est en position débordée, par exemple par rotation 36 du portique 16, pour procéder à la mise à l'eau du drone de surface 20 sur lequel la charge utile 26 est chargée (non représentée).On the figure 9 , the lifting gantry 16 of the handling system according to the invention, suitable for being actuated by the operator O 1 , is in the overflowed position, for example by rotation 36 of the gantry 16, to proceed with the launching of the surface drone 20 on which the payload 26 is loaded (not shown).

Le système de manutention, selon un aspect optionnel illustré par la figure 10, comprend en outre au moins un bras de guidage transversal 38 de mise à l'eau et/ou de récupération du support flottant, présentant une extrémité solidarisée au bordé de la plateforme 12.The handling system, according to an optional aspect illustrated by the figure 10 , further comprises at least one transverse guide arm 38 for launching and / or recovering the floating support, having one end secured to the side of the platform 12.

Chaque bras de guidage transversal est propre à venir au contact du bordé du berceau 18 du support flottant, et est actionnable par vérin(s) hydraulique(s) entre une position rétractée sensiblement colinéaire au bordé de la plateforme et une position déployée où chaque bras de guidage transversal forme un angle prédéterminé de déport 40 par rapport au bordé de la plateforme tel qu'illustré par la suite par la figure 11.Each transverse guide arm is adapted to come into contact with the plating of the cradle 18 of the floating support, and can be actuated by hydraulic jack (s) between a retracted position substantially collinear at the plating of the platform and a deployed position where each arm of transverse guide forms a predetermined offset angle 40 with respect to the plating of the platform as illustrated below by the figure 11 .

Sur la figure 11, les bras de guidage transversaux 38 sont déployés depuis le bordé de la plateforme navale 12. Ces bras de guidage transversaux 38 sont propre à être actifs une fois les câbles de mise à l'eau du support flottant partiellement dévirés. Les bras de guidage transversaux 38 viennent au contact du bordé du support flottant (défenses caoutchouc), afin de limiter ses mouvements relatifs d'embardée et de roulis, pour les phases où le support flottant n'est pas encore dans l'eau.On the figure 11 , the transverse guide arms 38 are deployed from the plating of the naval platform 12. These transverse guide arms 38 are able to be active once the cables for launching the floating support partially deflected. The transverse guide arms 38 come into contact with the plating of the floating support (rubber fenders), in order to limit its relative swerving and rolling movements, for the phases where the floating support is not yet in the water.

Le procédé 50 de manutention selon l'invention d'un drone de surface propre à être logé durant tout le procédé de manutention au sein d'un support flottant va être à présent expliqué en regard de la figure 12 représentant un organigramme d'un tel procédé.The handling method 50 according to the invention of a surface drone suitable for being housed during the whole handling process within a floating support will be present explained next to the figure 12 representing a flowchart of such a process.

Lors d'une première étape 52, le détachement, du berceau 18 du support flottant, du palonnier 22 de levage solidarisé au portique de levage 16 est effectué par l'opérateur O2, ce qui correspond à la position du système de manutention selon l'invention illustré par la figure 4.During a first step 52, the detachment of the cradle 18 of the floating support, of the lifting beam 22 secured to the lifting gantry 16 is carried out by the operator O 2 , which corresponds to the position of the handling system according to the invention illustrated by figure 4 .

Lors d'une étape 54, le débordement, en dehors de la plateforme 12, de l'ensemble formé par le palonnier de levage 22 et par le portique de levage 16 auquel le palonnier de levage 22 est solidarisé, par déplacement du portique de levage 22 en position débordée, le berceau 18 du support flottant restant à bord de la plateforme navale est mise en œuvre par exemple par l'opérateur O1 de la figure 5.During a step 54, the overflow, outside of the platform 12, of the assembly formed by the lifting beam 22 and by the lifting gantry 16 to which the lifting beam 22 is secured, by displacement of the lifting gantry 22 in the overflowed position, the cradle 18 of the floating support remaining on board the naval platform is implemented for example by the operator O 1 of the figure 5 .

Lors d'une étape 56, la manutention (i.e. le déplacement avant chargement) d'une charge utile 56 destinée à être chargée/déchargée sur le drone de surface 20 est mise en œuvre, notamment par l'opérateur O2 tel qu'illustré sur la figure 5.During a step 56, the handling (ie the movement before loading) of a payload 56 intended to be loaded / unloaded on the surface drone 20 is implemented, in particular by the operator O 2 as illustrated on the figure 5 .

Lors d'une étape 58, le chargement/déchargement de la charge utile sur le drone de surface est opéré notamment par l'opérateur O2 tel qu'illustré sur la figure 6.During a step 58, the loading / unloading of the payload on the surface drone is carried out in particular by the operator O 2 as illustrated on the figure 6 .

Lors d'une étape 60, la rétractation à bord de la plateforme, inverse au débordement, de l'ensemble formé par le palonnier de levage 22 et par le portique de levage 10, par déplacement du portique de levage 16 en une position à bord, le berceau 18 du support flottant restant à bord de la plateforme navale est opérée, notamment par l'opérateur O1 tel qu'illustré sur la figure 7.During a step 60, the retraction on board of the platform, opposite to the overflow, of the assembly formed by the lifting beam 22 and by the lifting gantry 10, by displacement of the lifting gantry 16 in a position on board , the cradle 18 of the floating support remaining on board the naval platform is operated, in particular by the operator O 1 as illustrated in the figure 7 .

Lors d'une étape 62, le rattachement au berceau 18 du support flottant du palonnier de levage 22 solidarisé au portique de levage 16 est effectué par l'opérateur O2 tel qu'illustré sur la figure 8.During a step 62, the attachment to the cradle 18 of the floating support of the lifting beam 22 secured to the lifting gantry 16 is carried out by the operator O 2 as illustrated on the figure 8 .

Lors d'une étape 64, la mise à l'eau et/ou la récupération du support flottant logeant le drone de surface 20 sur lequel la charge utile 26 est chargée par déplacement du portique de levage 16 en position débordée est opérée, notamment par l'opérateur O1 tel qu'illustré sur la figure 8.During a step 64, the floating support and / or recovery of the floating support housing the surface drone 20 on which the payload 26 is loaded by displacement of the lifting gantry 16 in the overflowed position is effected, in particular by the operator O 1 as illustrated on the figure 8 .

Un tel procédé de manutention permet un chargement puis une mise à l'eau lorsque les étapes 52 de détachement, 54 de débordement, 56 de manutention, 58 de chargement, 60 de rétractation, 62 de rattachement et 64 de mise à l'eau se succèdent tel qu'illustré par la figure 12, ou (de manière non représentée) permet une récupération puis un déchargement lorsque l'étape 64 de récupération est suivie par l'étape 52 de détachement, 54 de débordement, 56 de manutention, 58 de déchargement, 60 de rétractation et 62 de rattachement sont opérées successivement.Such a handling method allows loading and then launching when the steps 52 of detachment, 54 of overflow, 56 of handling, 58 of loading, 60 of retraction, 62 of attachment and 64 of launching succeed as illustrated by the figure 12 , or (not shown) allows recovery and unloading when step 64 of recovery is followed by step 52 of detachment, 54 of overflow, 56 of handling, 58 of unloading, 60 of retraction and 62 of attachment are operated successively.

D'autres combinaisons techniquement réalisables de ces étapes sont également opérables selon le procédé 50 de l'invention afin de produire une cinématique de manutention désirée.Other technically feasible combinations of these steps are also operable according to the method 50 of the invention in order to produce a desired handling kinematics.

Selon un aspect optionnel, l'étape 64 mise à l'eau et/ou récupération, du support flottant logeant le drone de surface 20 sur lequel la charge utile 26 est chargée comprend une étape 66 de déploiement et/ou rétractation respectivement des bras de guidage transversaux 38.According to an optional aspect, the step 64 launching and / or recovery of the floating support housing the surface drone 20 on which the payload 26 is loaded comprises a step 66 of deployment and / or retraction respectively of the arms of transverse guides 38.

Selon cet aspect optionnel, la mise à l'eau 64, du support flottant logeant le drone de surface 20 sur lequel la charge utile 26 est chargée, comprend, simultanément à l'action de mise à l'eau du portique de levage 16, une étape 66 de déploiement de bras de guidage transversaux 38 de mise à l'eau et/ou de récupération du support flottant, présentant chacun une extrémité solidarisée au bordé de la plateforme 12, chaque bras de guidage transversal étant propre à venir au contact du bordé du support flottant, et étant actionnable entre une position rétractée sensiblement colinéaire au bordé de la plateforme 12 et une position déployée où chaque bras de guidage transversal forme un angle prédéterminé de déport par rapport au bordé de la plateforme 12.According to this optional aspect, the launching 64, of the floating support housing the surface drone 20 on which the payload 26 is loaded, comprises, simultaneously with the launching action of the lifting gantry 16, a step 66 of deploying transverse guide arms 38 for launching and / or recovering the floating support, each having one end secured to the plating of the platform 12, each transverse guide arm being able to come into contact with the bordered by the floating support, and being operable between a retracted position substantially collinear at the edge of the platform 12 and a deployed position where each transverse guide arm forms a predetermined offset angle relative to the edge of the platform 12.

Selon cet aspect optionnel, la récupération 64, du support flottant logeant le drone de surface sur lequel la charge utile est chargée, comprend, simultanément à l'action de remontée du portique de levage, une étape 66 de rétractation de bras de guidage transversaux de mise à l'eau et/ou de récupération du support flottant, présentant chacun une extrémité solidarisée au bordé de la plateforme, chaque bras de guidage transversal étant propre à venir au contact du bordé du support flottant, entre une position déployée où chaque bras de guidage transversal forme un angle de déport prédéterminé par rapport au bordé de la plateforme et une position rétractée sensiblement colinéaire au bordé de la plateforme. A titre d'alternative, l'activation par déploiement et/ou rétractation des bras de guidage transversaux 38 n'est mis en œuvre que pour l'opération de mise à l'eau ou respectivement que pour l'opération de récupération.According to this optional aspect, the recovery 64 of the floating support housing the surface drone on which the payload is loaded, comprises, simultaneously with the lifting action of the lifting gantry, a step 66 of retraction of the transverse guide arms of launching and / or recovery of the floating support, each having one end secured to the plating of the platform, each transverse guide arm being able to come into contact with the plating of the floating support, between a deployed position where each transverse guide forms a predetermined offset angle relative to the plating of the platform and a retracted position substantially collinear to the plating of the platform. As an alternative, the activation by deployment and / or retraction of the transverse guide arms 38 is implemented only for the launching operation or respectively only for the recovery operation.

On conçoit ainsi que le système de manutention formé au moins du portique 16 et du support flottant comprenant deux parties à savoir le berceau 18 de réception du drone de surface 20 et le palonnier 22 permet de dégager facilement et rapidement à partir d'un seul opérateur le volume vertical nécessaire à la manutention de charge utile destinée à être chargée sur le drone de surface.It is thus conceivable that the handling system formed at least of the gantry 16 and the floating support comprising two parts, namely the cradle 18 for receiving the surface drone 20 and the lifter 22 makes it possible to release easily and quickly from a single operator the vertical volume necessary for the handling of payload intended to be loaded on the surface drone.

Par ailleurs, la manutention lors de la mise à l'eau et/ou récupération du drone de surface est optimisée par un système de bras de guidage transversaux qui permettent d'accompagner au mieux la manutention de mise à l'eau et/ou récupération en limitant les mouvements relatifs entre plateforme navale 12 et support flottant.In addition, the handling during launching and / or recovery of the surface drone is optimized by a system of transverse guide arms which make it possible to best support handling of launching and / or recovery by limiting the relative movements between naval platform 12 and floating support.
