Description
La présente invention concerne un dispositif de récupération sous-marine d'hydrocarbures ou de captage sous-marin d'eau chaude de source. The present invention relates to a device for underwater recovery of hydrocarbons or underwater collection of hot spring water.
Dans les années passées, on a développé un grand nombre de systèmes en vue de lutter contre la pollution en surface des mers et des lacs. Récemment, il s'est produit des naufrages au cours desquels des pétroliers ont sombré alors que leurs cuves étaient pleines. Quand le mazout transporté est moins lourd que l'eau et qu'il s'échappe des cuves, il remonte à la surface où on lutte contre la pollution avec des moyens de surface. Tout récemment, il s'est aussi produit une fuite dans un puit de pétrole sous-marin et là encore on tente de lutter contre la pollution due au mazout échappé par des moyens de surface. In recent years, a large number of systems have been developed in order to combat surface pollution of seas and lakes. Recently, there have been shipwrecks in which tankers have sunk while their tanks are full. When the fuel oil transported is lighter than water and it escapes from the tanks, it rises to the surface where pollution is combated with surface means. Very recently, there has also been a leak in an underwater oil well and here again we are trying to combat pollution due to fuel oil escaped by surface means.
Or, laisser le mazout remonter à la surface, c'est le laisser s'étaler en couche mince difficile à maîtriser. On sait, en effet, que les moyens de lutte de surface, non chimiques, ne peuvent avoir qu'un rayon d'action réduit bien inférieur aux étendues des nappes polluantes. Par ailleurs, avec les moyens chimiques, on perd les hydrocarbures échappés et on crée des complexes dont on n'est pas sûr qu'ils ne sont pas nuisibles pour la flore et la faune marines.However, letting the oil rise to the surface is to let it spread out in a thin layer that is difficult to control. We know, in fact, that surface non-chemical means of control can only have a reduced radius of action much smaller than the extent of polluting water tables. In addition, with chemical means, we lose the escaped hydrocarbons and we create complexes which we are not sure are not harmful to marine flora and fauna.
Un objet de la présente invention consiste à prévoir un dispositif qui soit capable de récupérer le mazout échappé, ou au moins une grande partie de celui-ci avant qu'il n'atteigne la surface. An object of the present invention is to provide a device which is capable of recovering escaped fuel oil, or at least a large part thereof before it reaches the surface.
Suivant une caractéristique de l'invention, il est prévu un dispositif se composant d'une grande bâche tendue horizontalement au-dessus de la source de fluide plus léger que l'eau, et d'un tuyau relié à un trou central de la bâche et dont la seconde extrémité est légèrement au-dessus du niveau de l'eau. According to a characteristic of the invention, there is provided a device consisting of a large tarpaulin stretched horizontally above the source of fluid lighter than water, and a pipe connected to a central hole in the tarpaulin. and whose second end is slightly above the water level.
Suivant une autre caractéristique, le tuyau est aplati avant sa mise en place pour utilisation, ce qui permet de le stocker enroulé sur un tambour. According to another characteristic, the pipe is flattened before it is put in place for use, which makes it possible to store it wound on a drum.
Suivant une autre caractéristique, la bâche est maintenue tendue par ses coins retenus tendus par des orins de bouées mouillées autour de la source du fluide à récupérer. According to another characteristic, the cover is kept taut by its retained corners stretched by orins of wet buoys around the source of the fluid to be recovered.
Suivant une autre caractéristique, la paroi est relativement mince et sa partie supérieure au voisinage du niveau de la surface est gainée. According to another characteristic, the wall is relatively thin and its upper part in the vicinity of the level of the surface is sheathed.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'exemples de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:
la Fig. 1 est une vue schématique en perspective du dispositif suivant l'invention, et
les Fig. 2 à 4 sont des vues schématiques en coupe verticale de divers équipements adaptables en haut du tuyau du dispositif de la Fig. 1.The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of exemplary embodiments, said description being made in relation to the accompanying drawings, among which:
Fig. 1 is a schematic perspective view of the device according to the invention, and
Figs. 2 to 4 are schematic views in vertical section of various equipment adaptable at the top of the pipe of the device of FIG. 1.
Le dispositif de la Fig. 1 comprend une grande bâche 1 dont les coins 2 sont maintenus écartés par des orins 3 reliant respectivement des bouées 4 à leurs corps-morts 5. Au centre de la bâche 1 est prévue une ouverture 6 à laquelle est raccordée l'extrémité inférieur d'un tuyau souple 7 qui débouche en 8 légèrement au-dessus du niveau de l'eau. The device of FIG. 1 comprises a large tarpaulin 1, the corners 2 of which are kept apart by orins 3 respectively connecting buoys 4 to their mooring lines 5. In the center of the tarpaulin 1 is an opening 6 to which the lower end of a flexible pipe 7 which opens at 8 slightly above the water level.
On suppose que la bâche 1 est tendue au-dessus d'un bateau 9 qui a sombré et qui laisse échapper du mazout 10, plus léger que l'eau. It is assumed that the sheet 1 is stretched over a boat 9 which has sunk and which lets out fuel oil 10, lighter than water.
En pratique, le mazout 10 monte se rassembler sous le centre de la bâche 1 qui subit une poussée vers le haut. La bâche prend alors la forme d'un dôme qui guide le mazout montant vers l'ouverture 6. Le mazout monte dans le tuyau souple 7.In practice, the fuel oil 10 rises to assemble under the center of the cover 1 which undergoes an upward thrust. The tarpaulin then takes the form of a dome which guides the rising fuel oil towards the opening 6. The fuel oil rises in the flexible pipe 7.
Il faut bien comprendre que la colonne de mazout dans le tube 7 obéit à la loi d'Archimède et qu'il y a équilibre quand son poids est égal à celui de l'eau déplacée. Le volume de l'eau déplacée est défini par le volume de la partie immergée du tuyau 7. Donc, pour avoir le même poids en mazout, plus léger, il faut que la colonne de mazout monte au-dessus du'niveau de l'eau d'une quantité proportionnelle au produit du rapport des densités de l'eau et du mazout et de la hauteur immergée du tuyau 7. Quand on maintient l'ouverture 8 du tuyau 7 au-dessus de l'eau, mais au-dessous du niveau maximum défini à partir de la relation mentionnée ci-dessus, le mazout s'écoule et peut être directement recueilli dans des réservoirs connectés à l'ouverture 8. Il se crée dans le tuyau 7 un courant de mazout qui monte plus ou moins vite selon la hauteur du tuyau et son état de surface interne. It should be understood that the oil column in the tube 7 obeys Archimedes' law and that there is equilibrium when its weight is equal to that of the displaced water. The volume of the displaced water is defined by the volume of the submerged part of the pipe 7. So, to have the same weight of fuel oil, lighter, the column of fuel oil must rise above the level of the water in a quantity proportional to the product of the ratio of the densities of water and fuel oil and the submerged height of the pipe 7. When the opening 8 of the pipe 7 is maintained above the water, but below of the maximum level defined from the relationship mentioned above, the fuel oil flows and can be directly collected in tanks connected to the opening 8. A stream of fuel oil is created in the pipe 7 which rises more or less quickly depending on the height of the pipe and its internal surface condition.
Il faut bien comprendre qu'à l'état statique, si on ne laisse pas le mazout s'écouler en haUt du tuyau, l'écart des pressions exercées par le mazout et l'eau sur la paroi du tuyau augmente avec l'altitude, si bien que premièrement le tuyau a tendance à s'ouvrir et que, deuxièmement, il peut être nécessaire de le gainer dans sa partie supérieure au voisinage de la surface de l'eau et au-dessus. It should be understood that in the static state, if the oil is not allowed to flow above the pipe, the difference in pressure exerted by the oil and the water on the wall of the pipe increases with altitude. , so that firstly the pipe tends to open and, secondly, it may be necessary to cover it in its upper part near and above the surface of the water.
A l'état dynamique, quand le mazout s'écoule, l'écart des pressions augmente moins qu'à l'état statique. In the dynamic state, when the fuel oil flows, the pressure difference increases less than in the static state.
En pratique, les orins 3 doivent être maintenus aussi verticaux que possible. C'est pourquoi les bouées 4 sont chacune constituées par un flotteur 11 sous lequel pend une poulie 12 sur la gorge de laquelle passe l'orin 3 à l'extrémité libre duquel pend un contre-poids 13. Ainsi la verticalité des orins peut être assurée au mieux même dans des mers soumises aux marées. Le tuyau 7 est représenté vertical, mais en fonction du niveau de la marée, il peut prendre une position oblique, le raisonnement indiqué plus haut restant valable. In practice, the orins 3 must be kept as vertical as possible. This is why the buoys 4 are each constituted by a float 11 under which hangs a pulley 12 on the groove of which passes the rope 3 at the free end of which hangs a counterweight 13. Thus the verticality of the rope can be best assured even in seas subject to tides. The pipe 7 is shown vertical, but depending on the level of the tide, it can take an oblique position, the reasoning indicated above remaining valid.
En pratique, la bâche 1 peut être en tissu souple ou en matière plastique, qui doit être imperméable. De préférence, le tuyau 7 est, en position de repos, aplati pour pouvoir être stocké sur un tambour peu encombrant, tout en permettant d'atteindre des profondeurs importantes. On a, en effet, intérêt à placer la bâche aussi près que possible de la source 9 pour éviter que des courants sous-marins ne dispersent le mazout 10. In practice, the sheet 1 can be made of flexible fabric or of plastic, which must be waterproof. Preferably, the pipe 7 is, in the rest position, flattened so that it can be stored on a space-saving drum, while making it possible to reach significant depths. It is in fact advantageous to place the tarpaulin as close as possible to the source 9 to prevent submarine currents from dispersing the fuel oil 10.
L'opération de mise en place du dispositif, quand une source 9 a été localisée, peut se dérouler comme suit. On commence par mouiller les corps-morts 5 autour de la source 9 en respectant des distances entre eux qui soient proches des longueurs des côtés de la bâche 1 et de manière que celle-ci soit centrée sur la source 9. Puis, on descend la bâche 1 dont les coins sont munis par exemple d'oeillets qui glissent le long des orins 3. A chaque coin est accroché un lest qui assure la descente de la bâche. Des plongeurs descendent bloquer les oeillets sur les orins par des moyens adéquats, tels que des coins. The operation of placing the device, when a source 9 has been located, can take place as follows. We start by wetting the moorings 5 around the source 9 while respecting the distances between them which are close to the lengths of the sides of the sheet 1 and so that it is centered on the source 9. Then, we descend the tarpaulin 1, the corners of which are provided, for example, with eyelets which slide along the orins 3. At each corner is attached a ballast which ensures the descent of the tarpaulin. Divers descend to block the eyelets on the moorings by suitable means, such as wedges.
On peut observer que le tuyau 7, supposé aplati au repos, le reste jusqu'à ce que le mazout commence à y monter. Puis on place l'extrémité 8 à bonne hauteur pour assurer l'écoulement. Au cours d'expériences, on a pu constater que le liquide montant dans le tuyau était uniquement du mazout à l'exclusion d'eau. Le dispositif permet donc de séparer efficacement le mazout de l'eau et de déverser ce mazout par 8 dans des récipients adéquats sans souiller la surface de l'eau.We can observe that the pipe 7, supposed to be flattened at rest, the rest until the fuel oil begins to rise there. Then place the end 8 at the correct height to ensure the flow. During experiments, it was found that the liquid rising in the pipe was only fuel oil excluding water. The device therefore makes it possible to efficiently separate the fuel oil from the water and to pour this fuel oil by 8 into suitable containers without contaminating the surface of the water.
Bien entendu, pour la mise en place du dispositif, on peut procéder différemment. Par exemple, on peut accrocher, à chaque coin de la bâche 1, un filin dont on laisse filer une longueur déterminée de manière à ce que chaque coin soit à la même hauteur. Le lestage des coins doit alors être suffisant pour empêcher la bâche de remonter, même partiellement, sous l'effet de la poussée ascentionnelle du mazout. I1 faut noter qu'avec les filins accrochés aux coins dont les oeillets sont guidés par les orins, on peut placer la bâche à la hauteur que l'on désire. Of course, for the installation of the device, one can proceed differently. For example, one can hang, on each corner of the sheet 1, a rope which is allowed to spin a determined length so that each corner is at the same height. The ballasting of the corners must then be sufficient to prevent the cover from going up, even partially, under the effect of the upward thrust of the fuel oil. It should be noted that with the ropes attached to the corners, the eyelets of which are guided by the ropes, the tarpaulin can be placed at the height that is desired.
De préférence, au voisinage de l'ouverture 6, le tuyau 7 peut s'élargir de manière à ce qu'en fonctionnement, le cône formé facilite le guidage du mazout. La bâche 1 peut présenter des plis qui facilite la formation du dôme. Preferably, in the vicinity of the opening 6, the pipe 7 can widen so that in operation, the cone formed facilitates the guiding of the fuel oil. The sheet 1 may have folds which facilitates the formation of the dome.
A la Fig. 1, on a représenté l'extrémité supérieure du tuyau encore portée par un tambour flottant 14, le mazout se déversant par 8 dans une cuve 15. I1 apparaît donc bien que le dispositif est très pratique à mettre en oeuvre, l'ensemble étant statique. Bien evidemment, la cuve 15 peut être rigide ou souple. In Fig. 1, there is shown the upper end of the pipe still carried by a floating drum 14, the fuel oil pouring by 8 into a tank 15. It therefore appears that the device is very practical to implement, the assembly being static . Obviously, the tank 15 can be rigid or flexible.
A la Fig. 2, on a montré une extrémité supérieure 16 de tuyau 7 portée verticalement par une cuve flottante 17, formée de boudins d'air, dans laquelle le mazout se déverse avant d'être repris par des pompes non montrées. La partie supérieure 16 du tuyau 7 est, de plus, renforcée par un gaine 18. In Fig. 2, an upper end 16 of pipe 7 has been shown, carried vertically by a floating tank 17, formed of air tubes, into which the fuel oil pours before being taken up by pumps not shown. The upper part 16 of the pipe 7 is further reinforced by a sheath 18.
A la Fig. 3, on a montré une extrémité 19 de tuyau 7, maintenue à flot par une bouée 20. La sortie de 19 est coiffée par un cône 21, dont le bord plonge dans l'eau, l'orifice supérieur du cône étant relié à une conduite d'aspiration 22. Dans ce cas, le volume intérieur du cône se remplit de mazout qui est pompé par 22. In Fig. 3, there is shown an end 19 of pipe 7, held afloat by a buoy 20. The outlet of 19 is capped by a cone 21, the edge of which plunges into water, the upper orifice of the cone being connected to a suction line 22. In this case, the interior volume of the cone is filled with fuel oil which is pumped by 22.
A la Fig. 4, on a montré une extrémité 23 de tuyau 7, maintenue à flot par une bouée 24, et dans laquelle plonge un tuyau d'aspiration 25. In Fig. 4, there is shown an end 23 of pipe 7, held afloat by a buoy 24, and in which a suction pipe 25 plunges.
A la Fig. 1, on a représenté une bâche rectangulaire, mais il doit être bien entendu que la bâche peut être polygonale, avec un grand nombre de côtés pour mieux circonscrire -le mazout libéré par la source. In Fig. 1, a rectangular tarpaulin has been shown, but it should be understood that the tarpaulin can be polygonal, with a large number of sides to better circumscribe the fuel oil released by the source.
Bien entendu, également, si la source 9 n'est pas ponctuelle, mais étendue, on peut juxtaposer des dispositifs suivant l'invention, les coins adjacents de deux bâches étant enfilés sur un même orin.Of course, also, if the source 9 is not punctual, but extended, it is possible to juxtapose devices according to the invention, the adjacent corners of two tarpaulins being threaded on the same rope.
Les exemples ci-dessus montrent que de nombreuses solutions sont possibles étant donné que le dispositif de l'invention met le mazout à la portée des équipements de pompage et de stockage, au-dessus du niveau de l'eau. The above examples show that many solutions are possible since the device of the invention puts the fuel oil within the reach of pumping and storage equipment, above the water level.
Dans la description qui précède, on a supposé que le fluide à capter était du mazout échapé, car il s'agit du problème le plus préoccupant actuellement. Mais il faut bien comprendre que le dispositif de l'invention permet de capter tout fluide immergé de densité inférieure à l'eau ambiante, donc en particulier de capter des eaux de sources chaudes qui existent en de nombreux points du globe. In the above description, it has been assumed that the fluid to be captured is escaped fuel oil, since this is the most worrying problem at present. However, it should be understood that the device of the invention makes it possible to capture any submerged fluid with a density less than ambient water, and therefore in particular to capture water from hot springs which exist at numerous points on the globe.
