Description

Navire comportant des moyens de traction d’un dock flottantVessel comprising traction means for a floating dock

La présente invention concerne un navire.The present invention relates to a ship.

Plus particulièrement l’invention concerne un navire qui comporte des moyens de traction d’un dock flottant de mise en œuvre d’une embarcation à partir de celui-ci.More particularly, the invention relates to a ship which comprises means for pulling a floating dock for implementing a boat from it.

Ces moyens de traction comprennent généralement une ligne de remorque du dock, par exemple sur l’un des bords du navire.These means of traction generally include a towing line from the dock, for example on one of the sides of the ship.

Ce type de navire est déjà connu dans l’état de la technique et permet de remplir plusieurs missions.This type of ship is already known in the state of the art and can fulfill several missions.

Ainsi par exemple l’une de ces missions peut être une mission dite de guerre des mines, dans laquelle l’embarcation mise en œuvre est par exemple constituée par un drone permettant d’explorer et d’analyser l’environnement voire de déployer des moyens de neutralisation par exemple des mines.So for example one of these missions can be a so-called mine warfare mission, in which the boat used is for example constituted by a drone making it possible to explore and analyze the environment or even to deploy means neutralization of mines, for example.

Le but de l’invention est de perfectionner encore ce type de navire.The aim of the invention is to further improve this type of ship.

À cet effet l’invention a pour objet un navire comportant des moyens de traction d’un dock flottant de mise en œuvre d’une embarcation à partir du navire, ces moyens de traction étant munis d’une ligne de remorque du dock, caractérisé en ce que le dock flottant comporte des moyens de trainée dans l’eau permettant de maintenir une tension dans la ligne de remorque dans une plage prédéterminée entre une valeur minimale et une valeur maximale.To this end, the subject of the invention is a ship comprising means for towing a floating dock for implementing a boat from the ship, these towing means being provided with a towing line of the dock, characterized in that the floating dock comprises drag means in the water making it possible to maintain a tension in the tow line in a predetermined range between a minimum value and a maximum value.

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

- les moyens de trainée comprennent des éléments structurels du dock ;- the drag means comprise structural elements of the dock;

- le dock présente une structure en forme de catamaran à deux flotteurs entre lesquels s’étendent des poutres de liaison et de support formant les moyens de trainée dans l’eau ;- the dock has a catamaran-shaped structure with two floats between which extend connecting and support beams forming the means of drag in the water;

- les moyens de traction sont prévus sur au moins l’un des bords du navire ;- the traction means are provided on at least one of the sides of the ship;

- les moyens de traction comprennent une perche de remorque à laquelle est accrochée la ligne de remorque du dock.- the traction means include a trailer pole to which the dock trailer line is attached.

L’invention sera mieux comprise à l’aide 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 with the help of 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 en perspective de derrière d’un dock flottant entrant dans la constitution d’un navire selon l’invention ; There represents a rear perspective view of a floating dock forming part of the constitution of a ship according to the invention;
  • La représente une vue en perspective de devant de ce dock flottant ; et There represents a front perspective view of this floating dock; And
  • La représente une vue de derrière du dock. There shows a rear view of the dock.

On a en effet illustré sur ces figures et en particulier sur la , un navire qui est désigné par la référence générale 1.We have in fact illustrated in these figures and in particular on the , a ship which is designated by the general reference 1.

Ce navire peut par exemple être un navire de déploiement d’un drone de guerre des mines, par exemple à partir de l’un de ses bords latéraux.This ship can for example be a ship for deploying a mine warfare drone, for example from one of its side edges.

Ce navire comporte alors des moyens de déploiement 2 d’un dock flottant désigné par la référence générale 3, de mise en œuvre d’une embarcation telle qu’un drone désigné par la référence générale 4.This ship then includes means 2 for deploying a floating dock designated by the general reference 3, for implementing a boat such as a drone designated by the general reference 4.

En fait ce navire comporte également des moyens de traction de ce dock flottant, ces moyens de traction ou de remorque étant désignés par la référence générale 5 sur ces figures.In fact this ship also includes traction means for this floating dock, these traction or trailer means being designated by the general reference 5 in these figures.

Ces moyens de remorque comportent par exemple une perche de remorque désignée par la référence générale 6 s’étendant à partir d’un bord du navire et à laquelle est accrochée une ligne de remorque du dock désignée par la référence générale 7.These towing means comprise for example a towing pole designated by the general reference 6 extending from one edge of the ship and to which is attached a dock tow line designated by the general reference 7.

Le dock flottant comporte également des moyens de trainée dans l’eau permettant de maintenir une tension dans la ligne de remorque dans une plage prédéterminée entre une valeur minimale et une valeur maximale.The floating dock also includes drag means in the water making it possible to maintain a tension in the tow line in a predetermined range between a minimum value and a maximum value.

En fait, ces moyens de trainée comprennent par exemple des éléments structurels du dock.In fact, these drag means include, for example, structural elements of the dock.

Ceux-ci sont illustrés sur les figures 2, 3 et 4 qui représentent un exemple de réalisation d’un dock.These are illustrated in Figures 2, 3 and 4 which represent an example of making a dock.

En fait, ce dock peut présenter une structure en forme de catamaran à deux flotteurs 10 et 11 représentés sur ces figures, et entre lesquels s’étendent des poutres de liaison et de support formant les moyens de trainée dans l’eau.In fact, this dock can have a catamaran-shaped structure with two floats 10 and 11 shown in these figures, and between which extend connecting and support beams forming the drag means in the water.

Ainsi par exemple on a représenté une poutre désignée par la référence générale 12 sur ces figures.For example, a beam designated by the general reference 12 is shown in these figures.

La carène de ce dock en forme de catamaran est optimisée sur une plage de trainée de manière à disposer d’une résistance à l’avancement suffisante pour éviter d’atteindre le seuil inférieur de détensionnement de la ligne de remorque, en particulier par exemple sur mer formée et pouvant conduire à des pics de tension néfastes pour la tenue mécanique de l’ensemble, pour la tenue de cap du dock, pour la préservation de la charge utile c’est-à-dire par exemple du drone etc...The hull of this catamaran-shaped dock is optimized over a drag range so as to have sufficient forward resistance to avoid reaching the lower threshold for detensioning the tow line, in particular for example on rough seas and which can lead to voltage peaks which are harmful to the mechanical strength of the assembly, to the heading of the dock, to the preservation of the payload, i.e. for example of the drone, etc.

Cette résistance à l’avancement est cependant réglée de manière à rester inférieure à un seuil maximum de manière à ne pas conduire à un surdimensionnement de la ligne de tension.This resistance to advancement is however adjusted so as to remain below a maximum threshold so as not to lead to oversizing of the tension line.

La trainée est donc optimisée.The drag is therefore optimized.

Ceci permet de réduire les fluctuations de tension dans la ligne de remorque du dock.This helps reduce voltage fluctuations in the dock trailer line.

Bien entendu d’autres modes de réalisation encore peuvent être envisagés.Of course, other embodiments can be considered.
