La présente invention concerne un navire comportant des moyens de déploiement d’un dock flottant de mise en œuvre d’une embarcation.The present invention relates to a ship comprising means for deploying a floating dock for implementing a boat.

Plus particulièrement, l’invention se rapporte à un tel navire qui comporte des moyens de déploiement de ce dock flottant sur au moins l’un des bords de celui-ci et qui est muni d’une ligne de remorque du dock et de bossoirs de suspension/manœuvre du dock.More particularly, the invention relates to such a vessel which comprises means for deploying this floating dock on at least one of the edges thereof and which is provided with a dock tow line and davits of the dock. suspension/dock maneuvering.

De tels navires sont déjà connus dans l’état de la technique et peuvent être utilisés pour différentes missions.Such ships are already known in the state of the art and can be used for different missions.

Ainsi par exemple, l’une des missions de ce type de navire peut être une mission dite de guerre des mines, dans laquelle le navire est adapté pour déployer une embarcation, telle qu’un drone, d’analyse et d’exploration de l’environnement, voire de déploiement de moyens de neutralisation de mines.For example, one of the missions of this type of ship can be a so-called mine warfare mission, in which the ship is adapted to deploy a boat, such as a drone, for analysis and exploration of the environment, or even deployment of mine neutralization means.

Le but de l’invention est de proposer des perfectionnements à ce type de navire.The aim of the invention is to propose improvements to this type of vessel.

A cet effet l’invention a pour objet un navire comportant des moyens de déploiement d’un dock flottant de mise en œuvre d’une embarcation sur au moins un bord du navire et muni d’une ligne de remorque du dock et de bossoirs de suspension/manœuvre du dock, comportant des moyens motorisés de déroulement/enroulement de câbles de support du dock, caractérisé en ce qu’il comporte des moyens de pilotage des moyens motorisés de déroulement/enroulement des câbles de support du dock pour maintenir une tension constante dans ceux-ci.To this end, the subject of the invention is a ship comprising means for deploying a floating dock for implementing a boat on at least one edge of the ship and provided with a dock tow line and davits. suspension/operation of the dock, comprising motorized means for unwinding/winding dock support cables, characterized in that it comprises means for controlling the motorized means for unwinding/winding the dock support cables to maintain a constant tension in these.

Suivant d’autres caractéristiques du navire selon l’invention prises seules ou en combinaison :According to other characteristics of the vessel according to the invention taken alone or in combination:

- les moyens de pilotage des moyens motorisés de déroulement/enroulement des câbles de support du dock sont contrôlés pour maintenir le fond du dock à un niveau d’immersion prédéterminé ;- the means for controlling the motorized means for unwinding/winding the dock support cables are controlled to maintain the bottom of the dock at a predetermined immersion level;

- le niveau d’immersion prédéterminé est à un niveau légèrement au-dessus du niveau de flottaison de l’embarcation pour amener celle-ci à franchir une marche lors de sa récupération dans le dock flottant.- the predetermined immersion level is at a level slightly above the flotation level of the boat to cause it to take a step when recovering from the floating dock.

L’invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d’exemple et faite en se référant aux dessins annexés, sur lesquels :The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the appended drawings, in which:

  • La représente une vue en perspective d’un navire selon l’invention ; There represents a perspective view of a ship according to the invention;
  • La représente une vue de derrière de ce navire illustrant le déploiement/récupération d’une embarcation dans un dock flottant ; et There represents a rear view of this vessel illustrating the deployment/recovery of a boat in a floating dock; And
  • La représente un schéma synoptique illustrant la structure et le fonctionnement de moyens de pilotage entrant dans la constitution d’un navire selon l’invention. There represents a synoptic diagram illustrating the structure and operation of control means forming part of the constitution of a ship according to the invention.

On a en effet illustré sur ces figures et en particulier sur la , un navire tel qu’un navire porteur désigné par la référence générale 1.We have in fact illustrated in these figures and in particular on the , a ship such as a carrier ship designated by the general reference 1.

Ce navire comporte sur au moins l’un de ses bords, des moyens de déploiement, désignés par la référence générale 2, d’un dock flottant, désigné par la référence générale 3, d’une embarcation désignée par la référence générale 4.This ship comprises on at least one of its edges, means of deployment, designated by the general reference 2, of a floating dock, designated by the general reference 3, of a boat designated by the general reference 4.

En fait, ces moyens permettent par exemple de mettre en œuvre une embarcation telle qu’un drone à partir de l’un des bords du navire.In fact, these means make it possible, for example, to operate a boat such as a drone from one of the sides of the ship.

Celui-ci comporte alors des moyens de remorque 5 du dock 3, ces moyens de remorque comportant par exemple une perche de remorque désignée par la référence générale 6, associée à une ligne de remorque désignée par la référence générale 7, permettant de remorquer le dock sur le côté du navire.This then comprises trailer means 5 of the dock 3, these trailer means comprising for example a trailer pole designated by the general reference 6, associated with a trailer line designated by the general reference 7, making it possible to tow the dock on the side of the ship.

En fait et comme cela est illustré sur la , les moyens de déploiement du dock flottant peuvent par exemple comporter un ou des bossoirs de suspension/manœuvre du dock, à l’avant et à l’arrière de celui-ci, comme par exemple le bossoir désigné par la référence générale 10 sur la .In fact and as illustrated on the , the means of deploying the floating dock can for example include one or more davits for suspending/maneuvering the dock, at the front and rear of it, such as for example the davit designated by the general reference 10 on the .

Ce ou ces bossoirs sont alors articulés sur le navire et sont déplaçables par rapport à celui-ci pour ranger ou déployer le dock et donc l’embarcation depuis et dans un hangar par exemple prévu sur le navire.This or these davits are then articulated on the ship and are movable relative to it to store or deploy the dock and therefore the boat from and in a hangar for example provided on the ship.

Il est alors prévu des moyens motorisés de déroulement/enroulement de câbles de support, comme par exemple les câbles désignés par les références 11 et 12 sur ces figures, qui sont placés à l’avant et à l’arrière du dock.Motorized means are then provided for unwinding/winding support cables, such as for example the cables designated by the references 11 and 12 in these figures, which are placed at the front and rear of the dock.

Selon l’invention, il est prévu des moyens de pilotage de ces moyens motorisés de déroulement/enroulement des câbles de support du dock, pour maintenir une tension constante dans ceux-ci.According to the invention, means are provided for controlling these motorized means for unwinding/winding the dock support cables, to maintain a constant tension therein.

La structure de ces moyens de pilotage est illustrée sur la où on a en effet représenté les câbles 11 et 12 associés à des moyens motorisés de déroulement/enroulement de ceux-ci, ces moyens étant désignés respectivement par les références générales 13 et 14 sur cette figure.The structure of these control means is illustrated on the where we have in fact shown the cables 11 and 12 associated with motorized means for unwinding/winding them, these means being designated respectively by the general references 13 and 14 in this figure.

Ces moyens comprennent par exemple des moteurs électriques associés à des treuils de façon classique.These means include, for example, electric motors associated with winches in a conventional manner.

Ces moyens sont pilotés par des moyens de commande, désignés par la référence générale 15 sur cette figure comportant tout automate ou calculateur approprié.These means are controlled by control means, designated by the general reference 15 in this figure comprising any appropriate automaton or calculator.

Ces moyens de commande sont alors associés à des moyens de détermination de la tension dans les câbles, ces moyens étant désignés par la référence générale 16 sur cette figure.These control means are then associated with means for determining the tension in the cables, these means being designated by the general reference 16 in this figure.

En fait, ces moyens de pilotage sont adaptés pour contrôler les moyens motorisés de déroulement/enroulement des câbles afin de maintenir le fond du dock 3 à un niveau d’immersion prédéterminé dans l’eau.In fact, these control means are adapted to control the motorized means of unwinding/winding of the cables in order to maintain the bottom of the dock 3 at a predetermined immersion level in the water.

Ce niveau d’immersion prédéterminé est alors à un niveau légèrement au-dessus du niveau de flottaison de l’embarcation pour amener celle-ci à franchir une marche lors de sa récupération dans le dock flottant.This predetermined immersion level is then at a level slightly above the flotation level of the boat to cause it to take a step when recovering from the floating dock.

Ainsi, l’embarcation est amenée à franchir une marche d’entrée dans le dock afin de pénétrer dans celui-ci, cette marche d’entrée devant être suffisante de manière à enfoncer le dock flottant lors de l’arrivée de l’embarcation, ce qui permet de maintenir un contact entre le dock et l’embarcation afin d’éviter ou de réduire les mouvements entre le dock et l’embarcation.Thus, the boat is required to cross an entry step into the dock in order to enter it, this entry step having to be sufficient to push down the floating dock when the boat arrives, which makes it possible to maintain contact between the dock and the boat in order to avoid or reduce movements between the dock and the boat.

Il va de soi que les moyens motorisés peuvent également être pilotés de façon indépendante à l’avant et à l’arrière du dock ce qui permet de régler l’assiette d’entrée du dock.It goes without saying that the motorized means can also be controlled independently at the front and rear of the dock, which allows the entry trim of the dock to be adjusted.

On conçoit alors qu’un tel système présente un certain nombre d’avantages dans la mesure où il permet d’améliorer la sécurité de manœuvre de l’embarcation.We can then see that such a system presents a certain number of advantages insofar as it makes it possible to improve the safety of maneuvering the boat.
