Abstract

A flexible envelope (1), optionally with a net, covers the entire leaking reservoir in the water. Floats (2) around the periphery of the envelope, support it. These are eventually used to form ballast weights on the sea bed. Blocks (3) with rings fixed to them are first located on the sea bed. The envelope and the floats (to become ballast) are guided by ropes passed through the rings. The envelope (and flooded floats/ballast) is now caused to descend, forming an interceptor immediately above the sunken vessel. To achieve this, boats distributed regularly around the periphery of the envelope, pull the ends of the guidance ropes passed through the rings.

Description

La présente invention concerne un dispositif destiné àThe present invention relates to a device intended for

confiner du fioul lourd ou tout autre liquide visqueux, au fond de l'eau, dans un environnement difficilement accessible. Ce confinement se fera autour du pétrolier contenant le fioul évitant ainsi que le pétrole s'échappe, remonte à la surface de l'eau et constitue une menace de pollution des côtes.  confine heavy fuel oil or any other viscous liquid to the bottom of the water in an environment that is difficult to access. This confinement will take place around the tanker containing the fuel oil, thus preventing the oil from escaping, rising to the surface of the water and constituting a threat of pollution of the coasts.

Le dispositif proposé est constitué en principal d'une enveloppe souple style filet de pêche ( 1).  The proposed device consists mainly of a flexible envelope style fishing net (1).

La dimension du filet sera telle que celui-ci recouvrira largement la zone à confiner.  The size of the net will be such that it will largely cover the area to be confined.

A la périphérie de ce filet sont attachés des "docks lest" ( 2) flottants que l'on remplira progressivement pour faire descendre l'ensemble vers le volume à recouvrir, nous les 15 désigneront " docks lest ".  At the periphery of this net are attached floating "ballast docks" (2) which will be gradually filled to bring the assembly down to the volume to be covered, we will designate them "ballast docks".

Les mailles du filet seront correctement dimensionnées pour ne pas laisser s'échapper le fioul et pour faciliter la descente du filet vers les profondeurs.  The mesh of the net will be correctly dimensioned so as not to let the fuel escape and to facilitate the descent of the net to the depths.

La matière constituant les mailles du filet sera choisie 20 imputrescible, et particulièrement résistante aux hydrocarbures La section du fil utilisé sera correctement dimensionnée pour assurer la résistance et la longévité dudit filet. Le filet pourra disposer d'une structure semi- rigide articulée permettant de le maintenir le plus plan possible au cours de sa descente Cette semi-rigidité devra pouvoir être facilement éliminée (enlèvement de goupilles par exemple) à l'arrivée sur le pétrolier pour permettre au filet d'entourer la coque endommagée.  The material constituting the meshes of the net will be chosen to be rot-proof, and particularly resistant to hydrocarbons. The section of the wire used will be correctly dimensioned to ensure the resistance and the longevity of said net. The net may have a semi-rigid articulated structure allowing it to be kept as flat as possible during its descent. This semi-rigidity must be able to be easily eliminated (removal of pins for example) on arrival on the tanker to allow with the net to surround the damaged hull.

Les "docks lest" seront dimensionnés pour assurer le maintien des bords du filet sur le fond de l'eau et pour compenser les forces verticales ascendantes causées par la masse maximale de pétrole capable de s'échapper des soutes.  The "ballast docks" will be sized to maintain the edges of the net on the bottom of the water and to compensate for the ascending vertical forces caused by the maximum mass of oil capable of escaping from the holds.

La dimension du filet sera calculée pour recouvrir une zone du pétrolier ou la totalité du pétrolier.  The size of the net will be calculated to cover an area of the tanker or all of the tanker.

Dans le cas d'une fuite pour une raison quelconque le premier filet pourra être recouvert d'un deuxième filet voire d'un troisième avec une probabilité forte que les mailles se chevauchent. Plusieurs petits filets munis de lests dimensionnés pourront être utilisés pour recouvrir les zones concernées Dans ce cas les filets devront être reliés entre eux par des 10 dispositifs style mousqueton.  In the event of a leak for any reason, the first net may be covered with a second net or even a third with a high probability that the meshes overlap. Several small nets fitted with dimensioned weights can be used to cover the areas concerned. In this case, the nets must be linked together by 10 carabiner-style devices.

Un petit filet pourra être construit et mis en place pour constituer un essai en vraie grandeur.  A small net can be constructed and put in place to constitute a full-scale test.

La descente du dispositif grand filet, ou petits filets pourra être contrôlée par des filins pour amener le filet à 15 l'endroit voulu sur le pétrolier.  The descent of the large net or small nets device can be controlled by ropes to bring the net to the desired location on the tanker.

Les filins seront passés dans les anneaux des blocs ( 3) constituant une boucle de la longueur nécessaire pour pouvoir disposer des deux extrémités à la surface de l'eau lorsque le bloc aura touché le fond.  The ropes will be passed through the rings of the blocks (3) constituting a loop of the length necessary to be able to have the two ends on the surface of the water when the block has touched the bottom.

Une extrémité du filin sera attachée au "dock lest", l'autre sera conservée sur le bateau de surface pour guider la maneuvre de descente.  One end of the rope will be attached to the "dock ballast", the other will be kept on the surface boat to guide the descent maneuver.

Plusieurs filins seront répartis à la périphérie du filet, chacun de ces filins étant attaché à une extrémité au filet 25 ou au " dock lest " et à l'autre extrémité à un bateau de surface. Variante du dispositif: il n'y a pas de " docks lest " on se contente d'attacher les filins directement à la périphérie du filet, il suffit ensuite que les bateaux tirent tous en même 30 temps et à la même vitesse sur les filins pour que l'ensemble des filins ainsi tractés entraîne le filet doucement vers la zone à recouvrir.  Several ropes will be distributed at the periphery of the net, each of these ropes being attached at one end to the net 25 or to the "dock ballast" and at the other end to a surface boat. Variant of the device: there are no "ballast docks" one is satisfied to attach the ropes directly to the periphery of the net, it is enough then that the boats all pull at the same time and at the same speed on the ropes so that all the cables thus towed gently pull the net towards the area to be covered.

Des systèmes style clip extensible auront été fixés sur les filins à quelques décimètres du bord du filet, ainsi en fin de manoeuvre les clips passant dans les anneaux s'ouvriront ass Gurant ainsi le blocage en position du filin et donc du filet. Au cours de la descente du filet, pour maintenir celui-ci $ dans une position horizontale, il est possible d'attacher d'autres filins à sa périphérie et de les mettre en tension en les reliant à d'autres bateaux.  Extensible clip style systems will have been attached to the ropes a few decimeters from the edge of the net, so at the end of the maneuver the clips passing through the rings will open assuring the blocking in position of the rope and therefore of the net. During the descent of the net, to keep it $ in a horizontal position, it is possible to attach other ropes to its periphery and to tension them by connecting them to other boats.

Les dessins annexés illustrent l'invention l'invention.  The accompanying drawings illustrate the invention.

La figure 1 montre le dispositif en cours de descente vers le 10 pétrolier La figure 2 montre le filet recouvrant le pétrolier, les fuites étant ainsi contenues.  FIG. 1 shows the device during its descent to the tanker. FIG. 2 shows the net covering the tanker, the leaks being thus contained.
