High tension horizontal cables connect the end of the buoy rods together, middle cables connect the buoys together, bottom cables connect the weights together, and vertical cables connect each weight to a buoy. These horizontal and vertical cables form a mesh with the tarpaulin attached to it. The tarpaulin can be fitted and removed from the mesh to be cleaned, dried and folded. Independent claims are also included for the following: (i) the installation of the above device, by progressively placing the tarpaulin of the device in the water, moving the boat around the oil slick, and fixing the two ends of the tarpaulin and device to the back of the boat; and (ii) recovering the above device, by progressive recovery of the tarpaulin and device from the water by moving the boat slowly in the opposite direction, and washing, drying and automatic folding of the tarpaulin and mesh.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un dispositif permettant d'empêcher des marées noires qui seraient causées par les nappes d'hydrocarbure provenant d'un navire qui a été accidenté ou qui a purgé ses réservoirs, ou encore de l'éruption accidentelle d'une tête de puits sous-marine.  The present invention relates to a device making it possible to prevent oil spills which would be caused by the oil slicks coming from a ship which has been accidented or which has drained its tanks, or also from the accidental eruption of a head of underwater well.

Ces pétroliers qui sont toujours confrontés à des tempêtes au milieu des océans, s'ils arrivent souvent à défier ces fortes intempéries et à ne pas couler, leurs réservoirs perdent quand-même des quantités d'hydrocarbure qui finissent toujours par provoquer des désastres écologiques.  These tankers, which are always facing storms in the middle of the oceans, if they often manage to defy these severe weather conditions and not to sink, their reservoirs still lose quantities of hydrocarbon which always end up causing ecological disasters.

Même si plusieurs techniques ont été adoptées et des améliorations ont été apportées à ce problème, le risque est loin d'être écarté.  Even if several techniques have been adopted and improvements have been made to this problem, the risk is far from being ruled out.

Ce dispositif selon l'invention permet de remédier à ces inconvénients. Il comporte en effet un navire spécial qui transporte une bâche dont la hauteur est de quelques mètres et la longueur de quelques milliers de mètres. Pour empêcher tout produit hydrocarbure de se déverser dans la mer et d'atteindre les rivages, le bateau jettera cette bâche dans l'eau de la même manière que l'on jette un filet de pêche à la mer. Puis tournant autour de la nappe pétrolière pour l'encercler et faciliter la récupération par le bateau de pompage. Les ballons qui se trouvent tout au long de la partie supérieure de la bâche et sa chambre à air permettront de la tenir sur l'eau contrairement au poids qui se trouve sur la partie inférieure qui vont la tirer vers le bas pour la tendre verticalement dans l'eau et former une sorte de mur.  This device according to the invention overcomes these drawbacks. It indeed includes a special ship which carries a tarpaulin whose height is a few meters and the length of a few thousand meters. To prevent any hydrocarbon product from spilling into the sea and reaching the shores, the boat will throw this tarpaulin into the water in the same way as a fishing net is thrown into the sea. Then turning around the tablecloth to encircle it and facilitate recovery by the pumping boat. The balloons which are located all along the upper part of the tarpaulin and its inner tube will allow it to be held on the water unlike the weight which is on the lower part which will pull it down to tension it vertically in water and form a kind of wall.

Selon des modèles particuliers de réalisation : - Un dispositif complet bien conçu pour s'adapter sur tout type de pétroliers ou de bateaux qui transportent ce genre d'hydrocarbure.  According to particular models of realization: - A complete device well designed to adapt to any type of tankers or boats which transport this kind of hydrocarbon.

- Le bateau qui sera doté de ce dispositif, sera doté aussi d'une station de pompage pour récupérer le hydrocarbure encerclé par la bâche.  - The boat which will be equipped with this device, will also be equipped with a pumping station to recover the hydrocarbon surrounded by the tarpaulin.

- Le bateau sera conçu uniquement pour encercler et empêcher le hydrocarbure de se propager dans la mer et d'atteindre la côte.  - The boat will be designed only to surround and prevent the oil from spreading into the sea and reaching the coast.

En référence à ces dessins, le dispositif comporte un bateau (l) qui porte une longue bâche (2) que l'on jette dans l'eau comme un filet de pêche. Les ballons (3) ainsi que la chambre à air (6) permet de garder une partie de cette bâche sur l'eau, l'autre partie sera tirée vers le bas par les poids (4) pour qu'elle se dresse verticalement en formant un mur.  With reference to these drawings, the device comprises a boat (l) which carries a long tarpaulin (2) which is thrown into the water like a fishing net. The balloons (3) and the air chamber (6) keep part of this tarpaulin on the water, the other part will be pulled down by the weights (4) so that it stands vertically in forming a wall.

Avec les ballons (3), la bâche (2) gardera toujours la partie supérieure au-dessus du niveau de mer, chaque tige des ballons (5) tire cette partie pour qu'elle reste verticale. Même avec de grosses vagues, la chambre à air de la bâche gardera toujours la partie entre les deux ballons sur l'eau.  With the balloons (3), the tarpaulin (2) will always keep the upper part above sea level, each rod of the balloons (5) pulls this part so that it remains vertical. Even with big waves, the air chamber of the tarp will still keep the part between the two balloons on the water.

Les câbles horizontaux du haut (9) relient l'extrémité du haut de la tige du ballon (5) les unes aux autres. Les câbles horizontaux du milieu (8) relient les ballons (3) les uns aux autres. Les câbles horizontaux du bas (7) relie les poids (4) les uns aux autres, et les câbles verticaux (10) relient chaque poids (4) à un ballon (3). Ces trois câbles horizontaux (9,8, 7) qui traversent toute la longueur de la bâche croisée par les câbles verticaux (10), forment une grille là où la bâche (2) s'accroche avec des points d'attaches (11).  The top horizontal cables (9) connect the top end of the balloon rod (5) to each other. The horizontal cables from the middle (8) connect the balloons (3) to each other. The bottom horizontal cables (7) connect the weights (4) to each other, and the vertical cables (10) connect each weight (4) to a balloon (3). These three horizontal cables (9,8, 7) which cross the entire length of the tarpaulin crossed by the vertical cables (10), form a grid where the tarpaulin (2) hangs with attachment points (11) .

L'installation du dispositif et sa récupération procédera en étapes suivantes : - Poser la bâche (2) en l'accrochant sur les points d'attaches (11) pour la fixer sur la grille à chaque fois qu'on la jette à l'eau.  The installation of the device and its recovery will proceed in the following stages: - Place the tarpaulin (2) by hanging it on the attachment points (11) to fix it on the grid each time it is thrown into the water.

Au fur et à mesure que le bateau (l) jette le dispositif dans l'eau, en faisant le tour de la nappe d'hydrocarbure (15), il revient à la tête de la bâche (13), c'est ainsi que la queue  As the boat (l) throws the device into the water, going around the sheet of oil (15), it returns to the head of the tarpaulin (13), this is how tail
