Description

NAVIRE RECUPERATEUR DE DECHETS OCEANIQUES  OCEANIC WASTE RECOVERY SHIP
[0001] La présente invention concerne un navire récupérateur de déchets océaniques. The present invention relates to a ship recovering ocean waste.
[0002] Sur une vaste étendue du Pacifique nord, évaluée le plus souvent à 3,5 millions de kilomètres carrés, se concentre une «soupe » que les experts évaluent a plusieurs millions de tonnes de débris plastiques accumulés et flottant entre deux eaux, dans une couche de 10 à 30 mètres d'épaisseur. [0002] Over a vast expanse of the North Pacific, evaluated most often at 3.5 million square kilometers, concentrates a "soup" that experts estimate at several million tonnes of plastic debris accumulated and floating between two waters, in a layer 10 to 30 meters thick.
[0003] Cette nappe du Pacifique nord est la plus grande décharge mondiale, maintenue en place par les courants marins, dont les projections de croissance datant de 2008 laissaient déjà penser qu'elle pourrait doubler de taille dans la décennie suivante. This tablecloth of the North Pacific is the largest discharge in the world, held in place by ocean currents, whose growth projections dating back to 2008 already suggested that it could double in size in the next decade.
[0004] En 2006, l'océanographe Charles Moore fut le découvreur de cette zone- vortex d'ordures constituée de déchets non biodégradés pour certains depuis 50 ans, non détectable par les satellites, car circulant sous la surface des eaux, composée de plastiques à 90 %, comme pour le volume global de tous les déchets flottant dans les océans. In 2006, the oceanographer Charles Moore was the discoverer of this area- trash vortex made of non-biodegraded waste for some 50 years, undetectable by satellites, as circulating under the water surface, composed of plastics at 90%, as for the overall volume of all floating waste in the oceans.
[0005] Cette menace est également évidente pour les écosystèmes marins, cette zone polluée du Pacifique est la manifestation d'un phénomène qui touche en effet l'ensemble des océans de la planète, car ces déchets flottent dans toutes les mers, y compris dans les régions polaires. A certains endroits, il y régnerait plus de déchets plastiques que de plancton. This threat is also evident for marine ecosystems, this polluted area of the Pacific is the manifestation of a phenomenon that affects indeed all the oceans of the planet, because this waste floats in all the seas, including in the polar regions. In some places, there would be more plastic waste than plankton.
[0006] Le nettoyage inéluctable de ces zones polluées représente donc à terme un chantier titanesque qui ne peut être qu'à la charge de la communauté internationale au sens large. Le nettoyage des océans est inévitable et urgent. Une aggravation persistante de la situation aboutirait à une catastrophe planétaire irréversible. [0007] Le but de la présente invention est de proposer un moyen pour récupérer les déchets flottants dans les mers. The inevitable cleaning of these polluted areas is ultimately a titanic project that can only be at the expense of the international community in the broad sense. The cleaning of the oceans is inevitable and urgent. A persistent aggravation of the situation would lead to an irreversible global catastrophe. The object of the present invention is to provide a means for recovering floating waste in the sea.
[0008] Selon l'invention, ce but est atteint par un navire récupérateur de déchets océaniques qui comporte au moins deux coques latérales qui déterminent un bassin entre elles. Selon la taille du navire il peut comporter aussi plus de deux coques latérales. According to the invention, this object is achieved by an ocean waste recovery vessel which comprises at least two lateral hulls which determine a basin between them. Depending on the size of the ship it may also include more than two side hulls.
[0009] Le navire selon l'invention est caractérisé en ce que le bassin entre les coques est ouvert à ses deux extrémités et comporte plusieurs sections successives de la proue vers la poupe du navire dont chacune est équipée d'au moins un dispositif de ramassage. Chaque section est équipée de dispositifs de ramassage aptes à ramasser des objets d'une taille spécifique, ou d'une plage de tailles spécifique. Les sections sont agencées de manière à ce qu'un dispositif apte à ramasser des objets plus petits soit disposé derrière un dispositif apte à ramasser des objets plus grands. The ship according to the invention is characterized in that the basin between the hulls is open at both ends and comprises a plurality of successive sections of the bow towards the stern of the vessel, each of which is equipped with at least one pickup device . Each section is equipped with pickup devices capable of picking up objects of a specific size, or a specific size range. The sections are arranged so that a device adapted to pick up smaller objects is disposed behind a device adapted to pick up larger objects.
[0010] La largeur globale de bassin du navire selon l'invention et sa hauteur peuvent déterminer une surface de traitement de la couche d'eau dans un plan vertical de la mer au moins égale à 1000 m2, avantageusement au moins égale à 2000 m2 et de préférence au moins égale à 3000 m2, traitée dans son intégralité par les dispositifs de ramassage, quelque soit leur conception ou leur agencement. The overall basin width of the vessel according to the invention and its height can determine a treatment surface of the water layer in a vertical plane of the sea at least equal to 1000 m 2 , preferably at least 2000 m 2 and preferably at least equal to 3000 m 2 , treated in its entirety by the pickup devices, whatever their design or arrangement.
[0011] Le navire peut être équipé d'un pont reliant les coques qui est équipé d'ouvertures permettant la récupération des objets ramassés par les dispositifs de ramassage. Ce pont technique peut comporter des superstructures permettant le traitement, le stockage et/ou le transbordement des objets ramassés. Le pont technique peut également être équipé de dispositifs de fixation et/ou d'escamotage solidaires des dispositifs de ramassage. The ship can be equipped with a bridge connecting the hulls which is equipped with openings for the recovery of objects picked up by the pickup devices. This technical bridge may include superstructures for the treatment, storage and / or transhipment of objects collected. The technical bridge may also be equipped with fastening devices and / or retraction secured to the pickup devices.
[0012] Un navire ayant ces caractéristiques permet de ramasser des déchets flottants de manière efficace et économique. Le navire présente une résistance à l'avancement limitée qui est réduite à la somme des largeurs des coques. Le navire peut donc se déplacer relativement rapidement et traiter une surface considérable. [0013] En avançant, les déchets flottants peuvent entrer dans le bassin du navire et seront ramassés dans les différentes sections par le ou les dispositifs de ramassage prévus dans la section respective correspondant à la taille de l'objet. Les différents dispositifs de ramassage sont conçus pour le ramassage d'objets de taille différente. C'est-à-dire que chaque dispositif est apte à ramasser des objets d'une taille comprise dans une plage de tailles spécifiques. A vessel having these characteristics makes it possible to collect floating waste in an efficient and economical manner. The vessel has limited forward resistance which is reduced to the sum of the hull widths. The ship can therefore move relatively quickly and treat a considerable area. Moving forward, the floating waste can enter the basin of the vessel and will be collected in different sections by the or the collection devices provided in the respective section corresponding to the size of the object. The different pickup devices are designed for picking up objects of different size. That is, each device is capable of picking up objects of a size within a range of specific sizes.
[0014] Les différentes sections sont agencées de telle manière qu'un dispositif apte à ramasser des objets plus petits est agencé derrière un dispositif apte à ramasser des objets plus grands. Cet agencement permet le ramassage des plus grands objets dans la partie avant du navire. Les dispositifs de ramassage de cette section peuvent être prévus particulièrement pour le ramassage de grands objets. Ils sont particulièrement stables mais laissent par contre passer les objets d'une taille au dessous de leur plage de tailles. Les sections successives sont conçues pour pouvoir ramasser des objets de tailles plus petites. La première section peut par exemple être conçue pour pouvoir ramasser les déchets les plus gros comme des conteneurs. Les dispositifs de ramassage des sections suivantes sont alors protégés contres des objets de cette taille et peuvent être d'une solidité moindre mais suffisante pour des objets plus petits. The different sections are arranged in such a way that a device capable of picking up smaller objects is arranged behind a device capable of picking up larger objects. This arrangement allows the collection of the largest objects in the front part of the ship. The collection devices of this section can be provided especially for the collection of large objects. They are particularly stable but allow objects that are smaller than their size range to pass. Successive sections are designed to pick up objects of smaller sizes. For example, the first section can be designed to pick up larger items such as containers. The collection devices of the following sections are then protected against objects of this size and may be of lesser strength but sufficient for smaller objects.
[0015] Le bassin délimité par les coques peut comprendre un plancher. Ce plancher peut relier les coques entre elles et stabilise la structure. [0016] Le navire selon l'invention est de préférence du type ballasté pour pouvoir naviguer avec des tirants d'eau différents. Les ballasts peuvent être dans les coques et/ou dans le plancher. L'avantage du ballastage est que le navire peut naviguer à différents niveaux pour pouvoir traiter une couche de déchets moins profonde par exemple, ou au contraire une couche plus épaisse. The basin defined by the hulls may comprise a floor. This floor can connect the hulls together and stabilizes the structure. The vessel according to the invention is preferably of the ballasted type to navigate with different drafts. The ballasts can be in the hulls and / or in the floor. The advantage of ballasting is that the ship can navigate at different levels to be able to treat a shallower layer of waste for example, or on the contrary a thicker layer.
[0017] Les coques peuvent être basées sur le concept SWATH (Small Waterplane Area Twin Hull). Les coques latérales peuvent posséder chacune une quille ballastée, permettant de faire flotter le navire à différents niveaux. Un SWATH est un navire à deux coques, chaque coque étant profondément immergée. La plateforme centrale est reliée aux coques par des jonctions minces au niveau de la flottaison. L'intérêt de cette configuration est d'améliorer la tenue à la mer par mauvais temps. Les quilles assurent dans ce cas de par leur emplacement, leur forme et leur volume, la stabilité hydrostatique et hydrodynamique du navire et rend le navire particulièrement stable et insensible aux effets déstabilisants des vagues. Les coques étant profondément immergées et la surface de flottaison réduite, le navire subit beaucoup moins les effets déstabilisants des vagues. Ses mouvements sont réduits de 20 à 50 % en comparaison d'un monocoque de même déplacement. Ce système peut être appliqué au navire selon l'invention. The hulls can be based on the SWATH concept (Small Waterplane Area Twin Hull). The side hulls can each have a ballast keel, allowing to float the ship at different levels. A SWATH is a two-hull ship, each hull being deeply submerged. The Central platform is connected to the hulls by thin junctions at the level of the waterline. The advantage of this configuration is to improve the seaworthiness in bad weather. In this case, the keels ensure the hydrostatic and hydrodynamic stability of the vessel by their location, shape and volume, and make the vessel particularly stable and insensitive to the destabilizing effects of the waves. The hulls being deeply submerged and the reduced buoyancy surface, the ship suffers much less the destabilizing effects of the waves. Its movements are reduced by 20 to 50% compared to a monohull of the same displacement. This system can be applied to the ship according to the invention.
[0018] Les sections du navire selon l'invention peuvent disposer de supports destinés à maintenir et/ou guider les dispositifs de ramassage. Ces supports peuvent notamment être une ou plusieurs cloisons longitudinales. Les cloisons des sections sont espacées l'une de l'autre pour permettre le passage d'objets de la taille correspondant à la section concernée. The sections of the ship according to the invention may have supports for holding and / or guide the pickup devices. These supports may in particular be one or more longitudinal partitions. The partitions of the sections are spaced from each other to allow the passage of objects of the size corresponding to the section concerned.
[0019] De préférence, la partie de proue du navire est équipée de dispositifs d'amortissement de chocs, préférablement sur toute sa hauteur immergée au moins, notamment d'un enrobage d'une matière ayant un pouvoir d'amortissement comme un enrobage caoutchouté et/ou un dispositif d'amortissement à ressort et/ou hydraulique et/ou hydropneumatique. Preferably, the bow part of the ship is equipped with shock absorbing devices, preferably over its entire height immersed at least, including a coating of a material having a damping power such as a rubberized coating and / or a spring and / or hydraulic and / or hydropneumatic damping device.
[0020] Avantageusement, au moins un dispositif de ramassage comporte une ou plusieurs plateformes ou bennes ou pelles remontantes, solidaires ou indépendantes du dispositif de ramassage, fixes ou articulées, et/ou comporte ou est constitué de filets ou treillis à mailles ou de barrières de filtration, notamment en textiles. Advantageously, at least one collection device comprises one or more platforms or skips or excavators rising, secured or independent of the pickup device, fixed or articulated, and / or comprises or consists of nets or mesh meshes or barriers filtration, especially in textiles.
[0021] Les dispositifs de ramassage, notamment de la première zone dans la partie avant du navire peuvent être constitués de filets à grosses mailles ou de treillis, en câble métallique, ou en mailles de métal, ou de toute matière ayant une solidité suffisante. Au bas des filets ou de treillis, une plateforme horizontale peut être prévue, constituant une avancée reliée au bas du filet ou de treillis, permettant de remonter les déchets flottants à différentes profondeurs. Cette plateforme peut être constituée par un prolongement du filet ou du treillis, des fourches ou un plateau métallique. Dans une autre version, la plateforme de remontée des déchets est indépendante du filet ou du treillis. [0022] Les dispositifs de ramassage peuvent également être constitués de bennes grillagées, de tapis roulants rotatifs comportant notamment des moyens de levage solidaires ou indépendant du tapis roulant, en particulier des pelles de levage, des bennes grillagés ou des crochets, fixes ou articulés. [0023] Les dispositifs de ramassages sont de préférence relevables et/ou escamotables et/ou amovibles. Selon un mode de réalisation particulièrement avantageux de l'invention, au moins une section est équipée d'au moins deux dispositifs de ramassage successifs. Un dispositif peut dans cette configuration être remonté, par exemple pour des raisons de maintenance ou parce qu'il est bloqué par un objet ramassé, et le deuxième dispositif peut assurer le ramassage entretemps et peut empêcher les déchets d'une taille non-adaptée d'arriver dans la section suivante. The collection devices, including the first zone in the forward part of the ship may consist of large mesh nets or trellis, wire rope, or metal mesh, or any material having sufficient strength. At the bottom of the nets or trellis, a horizontal platform can be provided, constituting an advance connected to the bottom of the net or trellis, to raise the floating waste at different depths. This platform can be consisting of an extension of the net or trellis, forks or a metal tray. In another version, the platform of lifts waste is independent of the net or the trellis. The collection devices may also consist of mesh trucks, rotating conveyor belts comprising in particular lifting means integral or independent of the conveyor belt, in particular lifting shovels, wire trucks or hooks, fixed or articulated. The collection devices are preferably liftable and / or retractable and / or removable. According to a particularly advantageous embodiment of the invention, at least one section is equipped with at least two successive collection devices. In this configuration, a device can be reassembled, for example for reasons of maintenance or because it is blocked by a picked-up object, and the second device can ensure collection in the meantime and can prevent waste of an unadapted size. arrive in the next section.
[0024] Le navire peut être équipé d'un dispositif de détection et de localisation des objets flottants ou immergés sous la surface de la mer, et se trouvant dans la couche d'eau sur la route du navire, afin de permettre au navire de ralentir suffisamment à l'avance en vue du ramassage de gros déchets. The vessel may be equipped with a device for detecting and locating floating or submerged objects under the sea surface, and lying in the layer of water on the ship's road, in order to allow the ship to slow down sufficiently in advance to pick up large pieces of waste.
[0025] Les supports destinés à maintenir et/ou guider les dispositifs de ramassage, comme par exemple des cloisons longitudinales, sont avantageusement déplaçables latéralement et/ou amovibles. Ceci permet d'en augmenter ou en réduire le nombre, afin de pourvoir augmenter ou réduire leur écartement, ou pour permettre l'installation de dispositifs de ramassage différents, par exemple plus évolués en cas d'une actualisation technique ultérieure. The supports for maintaining and / or guiding the pickup devices, such as longitudinal partitions, are preferably laterally movable and / or removable. This makes it possible to increase or reduce the number, in order to increase or reduce their spacing, or to allow the installation of different collection devices, for example more advanced in case of a subsequent technical update.
[0026] Au moins une partie des dispositifs de ramassage peut présenter une inclinaison vers l'arrière du navire. Selon un mode de réalisation avantageux de l'invention les dispositifs peuvent présenter une inclinaison vers l'arrière formant un angle inférieur à 45° par rapport à l'horizontal, en particulier inférieur à 30° et de préférence inférieur à 15°. Ceci s'applique notamment aux dispositifs des sections qui sont aptes à ramasser des objets de taille plus petite. Ces dispositifs sont plus fragiles parce que leur maillage ou treillage est plus fin. L'inclinaison permet de réduire les forces exercées par un objet qui heurte le dispositif. At least a portion of the pickup devices may have an inclination towards the rear of the ship. According to an advantageous embodiment of the invention, the devices may have a backward inclination forming an angle less than 45 ° with respect to the horizontal, in particular less than 30 °, and preferably less than 15 °. This applies in particular to section devices that are able to pick up objects of smaller size. These devices are more fragile because their mesh or trellis is finer. The inclination reduces the forces exerted by an object that hits the device.
[0027] Les dispositifs de ramassage comportent de préférence des moyens de ramassage comme des tapis roulants, treillis, pelles ou bennes montés sur un système rotatif. Ces moyens de ramassage se déplacent ainsi pendant le fonctionnement du dispositif selon un plan incliné, de préférence presque horizontal, vers l'arrière en remontant en même temps vers le pont du navire. The collection devices preferably comprise collecting means such as treadmills, trellis, excavators or skips mounted on a rotary system. These collecting means thus move during the operation of the device according to an inclined plane, preferably almost horizontal, towards the rear while going up at the same time towards the deck of the ship.
[0028] La vitesse de fonctionnement de ces dispositifs peut être régulée afin d'obtenir le meilleur compromis possible entre la vitesse de déplacement relative des moyens de ramassage, et la vitesse de déplacement du navire, qui peut elle aussi varier en fonction de conditions multiples. Plus la vitesse de déplacement vers l'arrière des moyens de ramassage est élevée, plus on réduit la résistance à l'avancement de ces moyens de ramassage, mais plus on réduit l'efficacité du ramassage des déchets. Il faut donc pouvoir réguler la vitesse de fonctionnement des dispositifs de ramassage en fonction de la vitesse de déplacement du navire et des autres facteurs en présence pour obtenir une efficacité optimale. The operating speed of these devices can be regulated to obtain the best possible compromise between the relative speed of movement of the pickup means, and the speed of movement of the ship, which can also vary depending on multiple conditions . The higher the speed of the rearward movement of the collection means, the more the resistance to the advancement of these collecting means is reduced, but the efficiency of the collection of waste is reduced. It is therefore necessary to be able to regulate the speed of operation of the collection devices as a function of the speed of movement of the vessel and the other factors involved to obtain optimum efficiency.
[0029] L'inclinaison des moyens de ramassage comme des bennes et des pelles doit bien entendu être adaptée à l'inclinaison des dispositifs de ramassage dont ils font partie pour garder leur efficacité. The inclination of the collection means such as skips and shovels must of course be adapted to the inclination of the pickup devices they are part of to keep their effectiveness.
[0030] Une partie des dispositifs de ramassage peut être mobile dans le sens inverse de la direction de déplacement du navire. Les dispositifs de ramassage pour les objets plus petits sont d'une part plus fragiles parce que leur maillage ou treillage est plus fin, et ils ont d'autre part une plus grande résistance à l'avancement dans la couche d'eau. Ils peuvent donc être mobiles dans leur section dans le sens longitudinal, par exemple sur des rails. Un dispositif en position de ramassage peut alors se déplacer dans le sens inverse de la direction du navire pour réduire la vitesse d'impact d'un objet sur le dispositif ainsi que pour réduire la résistance à l'avancement. La vitesse effective d'un impact ou la résistance effectivement exercée est la différence entre la vitesse du navire et la vitesse de déplacement du dispositif dans le sens inverse. Arrivé à la fin de sa section le dispositif peut être remonté, transporté vers l'avant de sa section et recommence son parcours. [0031] Le navire peut être équipé d'un pont permettant le stockage, le traitement et/ou le transbordement des objets ramassés vers d'autres navires. Le pont peut être équipé de cabines et locaux de cuisines et autres pour l'équipage pouvant aller jusqu'à plus de 100 personnes. [0032] Le navire peut être équipé de moyens de propulsion diesel électrique, de rotors Flettner et/ou de voiles solaires. Part of the pickup devices may be movable in the opposite direction of the direction of movement of the ship. The collection devices for smaller objects are, on the one hand, more fragile because their mesh or trellis is thinner, and on the other hand they have greater resistance to advancement in the layer of water. They can therefore be movable in their section in the longitudinal direction, for example on rails. A device in the collection position can then move in the opposite direction of the ship's direction to reduce the speed of impact of an object on the device as well as to reduce the drag. The actual speed of an impact or resistance actually exerted is the difference between the speed of the ship and the speed of movement of the device in the opposite direction. Arrived at the end of its section the device can be reassembled, transported towards the front of its section and starts again its course. The vessel can be equipped with a bridge for storing, processing and / or transhipment of objects picked up to other vessels. The deck can be equipped with cabins and kitchens and other facilities for the crew of up to more than 100 people. The ship may be equipped with diesel electric propulsion means, Flettner rotors and / or solar sails.
[0033] La propulsion principale peut être assurée par des hélices, hydrojets ou pods ou toute autre technique adaptée. Un carénage d'hélices sera avantageux pour les protéger d'éventuels gros déchets. The main propulsion can be provided by propellers, hydrojets or pods or any other suitable technique. A propeller fairing will be advantageous to protect them from possible large waste.
[0034] Les faces extérieures des coques latérales du navire peuvent être équipées de supports ou dispositifs, fixes ou amovibles, destinés à la fixation de panneaux publicitaires souples ou rigides, fixes ou amovibles. De tels supports ou dispositifs permettent aux sponsors de faire réaliser leur panneau publicitaire individuellement. Installer ces panneaux ne prend que très peu de temps et n'immobilise pas le navire. L'installation peut être réalisée pendant la maintenance régulière du navire ou même pendant une mission par temps calme. [0035] L'invention est expliquée plus précisément ci-après à l'aide des figures ci- jointes qui montrent des modes de réalisation de l'invention de manière schématique : The outer faces of the side hulls of the ship may be equipped with supports or devices, fixed or removable, for fixing flexible or rigid advertising panels, fixed or removable. Such media or devices allow sponsors to have their advertising billboards made individually. Installing these panels takes very little time and does not stop the vessel. The installation can be carried out during the regular maintenance of the ship or even during a mission in calm weather. The invention is explained more precisely below with the aid of the attached figures which show embodiments of the invention schematically:
[0036] La figure 1 illustre de manière schématique un navire selon l'invention en perspective de devant ; Figure 1 schematically illustrates a vessel according to the invention in front perspective;
[0037] La figure 2 illustre de manière schématique un navire selon l'invention en coupe longitudinale ; [0038] La figure 3 illustre un navire selon l'invention de manière schématique en coupe horizontale. [0037] Figure 2 schematically illustrates a vessel according to the invention in longitudinal section; [0038] Figure 3 illustrates a ship according to the invention schematically in horizontal section.
[0039] Il est précisé que les figures montrent l'invention de manière purement schématique pour expliquer son mode de fonctionnement général. Les figures ne sont ni à l'échelle ni complètes mais montrent de manière schématique uniquement les éléments qui sont nécessaires pour apprécier l'invention. It is noted that the figures show the invention purely schematically to explain its general operating mode. The figures are neither scale nor complete but schematically show only the elements that are necessary to appreciate the invention.
[0040] La figure 1 illustre de manière schématique un navire 1 selon l'invention en perspective de devant. Le navire 1 comporte trois coques latérales 2 qui déterminent deux bassins 3 entre elles. Les bassins 3 sont ouverts aux deux extrémités dont l'ouverture avant est visible sur la figure. Les bassins 3 comprennent un plancher 4 et sont chacun divisé par une cloison longitudinale 30.Figure 1 schematically illustrates a vessel 1 according to the invention in front perspective. The ship 1 has three lateral hulls 2 which determine two basins 3 between them. The basins 3 are open at both ends whose front opening is visible in the figure. The basins 3 comprise a floor 4 and are each divided by a longitudinal partition 30.
Les bassins 3 comportent trois sections successives dans la direction de déplacement D du navire dont chacune est équipée de plusieurs dispositifs de ramassage qui remontent les déchets entrés dans les bassins 3 vers le pont-usine 5 du navire. The basins 3 have three successive sections in the direction of displacement D of the ship, each of which is equipped with several collection devices that bring the waste entering the basins 3 to the factory bridge 5 of the ship.
[0041] La hauteur des coques 2 du navire 1 décrit ici à titre d'exemple est d'environ 50 m. Un tel navire peut intervenir dans une couche d'eau allant jusqu'à 35 m de profondeur. Les coques sont ballastées pour permettre au navire de flotter à différents niveaux. The height of the hulls 2 of the ship 1 described here by way of example is about 50 m. Such a vessel can intervene in a layer of water up to 35 m deep. The hulls are ballasted to allow the ship to float at different levels.
[0042] Le navire a une longueur d'environ 320 m et est divisé en plusieurs sections comme décrit ci-après. Toutes les mesures indiquées ici sont données à titre indicatif uniquement. Selon la zone d'intervention prévue, le navire selon l'invention peut être plus grand ou plus petit, comporter plus ou moins de coques ou plus ou moins de sections. [0043] Le principe général de la configuration du navire 1 selon l'invention est que les bassins 3 ouverts à leurs deux extrémités permettent le passage de la mer en limitant la résistance à l'avancement du navire à la somme des largeurs des coques 2 et des cloisons longitudinales 30 qui se trouvent entre les coques 2 et qui servent de supports aux dispositifs de ramassage des déchets non représentés sur la figure 1. The vessel has a length of about 320 m and is divided into several sections as described below. All measurements listed here are for reference only. Depending on the area of intervention planned, the vessel according to the invention may be larger or smaller, with more or fewer hulls or more or fewer sections. The general principle of the configuration of the vessel 1 according to the invention is that the basins 3 open at both ends allow the passage of the sea by limiting the resistance to the advancement of the ship to the sum of the widths of the hulls 2 and longitudinal partitions 30 which are between the shells 2 and which serve from supports to waste collection devices not shown in FIG. 1.
[0044] Au-dessus des coques 2 se trouve un pont-usine 5 comprenant tous les équipements permettant le traitement des déchets. Il fait essentiellement la largeur du navire. Above the shells 2 is a factory bridge 5 including all the equipment for the treatment of waste. It is essentially the width of the ship.
[0045] En configuration normale, le plancher du pont-usine 5 se trouve entre 10 m et 12 m au-dessus du niveau de la mer pour permettre au navire de continuer à travailler par mer formée ou tempête. In normal configuration, the floor of the bridge-factory 5 is between 10 m and 12 m above sea level to allow the ship to continue working by sea formed or storm.
[0046] La première section 11 est destinée au ramassage des plus gros déchets. Elle est située dans les premiers 50 m du navire et regroupe les dispositifs destinés au ramassage des très gros déchets, tels des conteneurs ou des billes de bois, pouvant peser 20 tonnes ou plus, et généralement de grandes dimensions. The first section 11 is intended for the collection of the largest waste. It is located in the first 50 m of the ship and includes devices for the collection of very large waste, such as containers or logs, weighing 20 tons or more, and generally large.
[0047] Le pont-usine 5 peut comporter plusieurs postes de transbordement des déchets pour pouvoir transborder simultanément sur les différents postes, les déchets dans les différentes cales d'un navire positionné sur l'un de ses côtés. Les moyens de transbordement sont notamment des grues 51, des toboggans ou des tapis roulants. The plant bridge 5 may include several transhipment points for waste to be simultaneously transship on the different stations, the waste in the different holds of a ship positioned on one of its sides. The transhipment means include cranes 51, slides or treadmills.
[0048] Le navire est équipé de moyens de propulsion diesel électrique. En plus, des rotors du type Flettner 9, encore appelées turbo-voiles, sont ajoutés afin de réduire la consommation du navire d'environ 30%. The vessel is equipped with diesel electric propulsion means. In addition, Flettner 9-type rotors, also known as turbo-sail, are added to reduce the vessel's consumption by about 30%.
[0049] La figure 2 illustre un navire 1 selon l'invention de manière schématique en coupe longitudinale. On voit bien le bassin 3 qui s'étend sur toute la longueur du navire et qui est divisé en trois sections 11 , 12, 13. Chaque section est équipée de plusieurs dispositifs de ramassage 21 , 22, 23 de déchets. Le bassin 3 a une ouverture à la proue 6 et à la poupe 7 du navire pour permettre à l'eau de mer de traverser les sections 11 , 12, 13. Les dispositifs de ramassage 21 , 22, 23 remontent les déchets entrés dans le bassin 3 vers le pont-usine 5 pour être traités, stockés et/ou transbordés vers d'autres navires. [0050] Les dispositifs de ramassage 21 de la première section 11 sont destinés à ramasser les plus gros déchets. La première section 11 a une longueur d'environ 50 m. Elle regroupe les dispositifs 21 destinés au ramassage des très gros déchets, comme par exemple des conteneurs perdus par un navire porte-conteneurs ou des billes de bois, pouvant peser 20 tonnes ou plus, et généralement de grandes dimensions. Figure 2 illustrates a vessel 1 according to the invention schematically in longitudinal section. We can see the basin 3 which extends over the entire length of the ship and which is divided into three sections 11, 12, 13. Each section is equipped with several collection devices 21, 22, 23 of waste. The basin 3 has an opening at the bow 6 and at the stern 7 of the ship to allow the seawater to cross the sections 11, 12, 13. The collection devices 21, 22, 23 return the waste entering the basin 3 to the factory deck 5 to be processed, stored and / or transhipped to other vessels. The pickup devices 21 of the first section 11 are intended to pick up the largest waste. The first section 11 has a length of about 50 m. It includes devices 21 for the collection of very large waste, such as containers lost by a container ship or logs, weighing 20 tons or more, and generally large.
[0051] La première section 11 dispose de deux dispositifs de ramassage 21 successifs. Ils sont constitués de filets à grosses mailles ou de treillis, en câble métallique, ou en mailles de métal, ou de toute matière ayant une solidité suffisante. Au bas des filets ou des treillis, une plateforme horizontale 211 constituant une avancée reliée au bas du filet ou du treillis, permet de remonter les déchets flottants à différentes profondeurs. Cette plateforme 211 est constituée par un prolongement de filet ou du treillis, des fourches, un plateau métallique ou toute autre moyen adapté. The first section 11 has two successive collection devices 21. They consist of nets with large mesh or mesh, wire rope, or mesh of metal, or any material having sufficient strength. At the bottom of the nets or trellises, a horizontal platform 211 constituting an advance connected to the bottom of the net or trellis, makes it possible to raise the floating trash at different depths. This platform 211 is constituted by a net extension or trellis, forks, a metal tray or any other suitable means.
[0052] Les déchets de la première section 11 sont remontés sur le pont avant du navire qui constitue une surface de manutention importante. Le pont comporte les ouvertures nécessaires aux remontées des déchets au moyen des dispositifs de ramassage. Des surfaces de manutention et d'entreposage avec treuil ou grues 51 peuvent être prévues et des chariots sur rails peuvent être aménagés pour permettre le déplacement, puis le stockage de ces gros déchets, à l'arrière du navire. The waste of the first section 11 are reassembled on the front deck of the vessel which is a large handling area. The bridge has the openings necessary for the lifts of the waste by means of the collection devices. Handling and storage areas with winch or cranes 51 can be provided and rail carriages can be arranged to allow the movement and storage of these large pieces of waste at the rear of the vessel.
[0053] La première section 11 comprend deux rangées de dispositifs de ramassage 21 , de telle manière que lorsqu'une rangée de dispositif est en cours de phase de remontée des déchets sur le pont-usine 5, au moins une autre rangée continue de récupérer les déchets en les empêchant d'arriver en deuxième section 12. The first section 11 comprises two rows of pickup devices 21, so that when a device row is being lifted phase of the garbage on the factory deck 5, at least one other row continues to recover waste by preventing them from arriving in second section 12.
[0054] La proue 6 du navire 1 est équipée de dispositifs de détection et de localisation 8 des objets flottants dans la couche d'eau se trouvant sur la route du navire, afin de permettre au navire de ralentir suffisamment à l'avance en vue du ramassage des gros déchets. [0055] La deuxième section 12 du navire a une longueur d'environ 50 m. Elle est conçue pour récupérer les déchets de tailles moyennes, allant de la taille d'une bouteille plastique à des débris de l'ordre de 5 cm. The bow 6 of the ship 1 is equipped with devices for detecting and locating floating objects 8 in the layer of water on the ship's road, in order to allow the ship to slow down sufficiently in advance with a view to collection of large waste. The second section 12 of the ship has a length of about 50 m. It is designed to recover medium-sized waste, ranging from the size of a plastic bottle to debris of the order of 5 cm.
[0056] Dans la configuration représentée sur la figure, la deuxième section comprend trois rangées de dispositifs de ramassage 22. Les dispositifs de ramassage 22 sont pratiquement identiques à ceux de la première section, mis à part la taille des équipements et du maillage permettant le ramassage, puisque les déchets à ramasser dans cette section 12 sont beaucoup plus petits. Les deux premières rangées sont équipés de plateformes 221 , la dernière de fourches 222 sur un tapis roulant rotatif. Les plateformes et fourches sur tapis roulant rotatif présentent une équivalence technique et peuvent librement être remplacées les unes par les autres. In the configuration shown in the figure, the second section comprises three rows of pickup devices 22. The pickup devices 22 are substantially identical to those of the first section, apart from the size of the equipment and the mesh allowing the pickup, since the garbage to pick up in this section 12 is much smaller. The first two rows are equipped with platforms 221, the last of forks 222 on a rotary conveyor. The platforms and forks on rotating treadmill have a technical equivalence and can freely be replaced by each other.
[0057] Les dispositifs de ramassage débouchent directement dans le pont-usine 5 par des ouvertures 52 de plancher du pont-usine prévues à cet effet, par lesquelles les déchets sont récupérés pour être traités et stockés. [0058] La troisième section 13 du navire a une longueur d'environ 200 m. Elle emploie le maillage ou treillage le plus fin, donc les filets ou treillages métalliques les plus fragiles, à cause de leur plus grande résistance à l'avancement dans la couche d'eau. [0059] Afin de permettre au navire de maintenir une vitesse élevée, les dispositifs de ramassage 23 de la troisième section 13 sont mobiles dans le sens inverse I de la direction D de déplacement du navire. Ainsi, lorsque le navire avance à la vitesse de 40 km/h, la vitesse des dispositifs de ramassage 13 peut être de 20 ou 30 km/h en sens inverse I, ce qui réduit la vitesse effective du déplacement des dispositifs de ramassage à 20 ou 10 km/h. The collection devices open directly into the factory deck 5 through openings 52 of the deck-plant provided for this purpose, by which the waste is recovered for processing and storage. The third section 13 of the ship has a length of about 200 m. It uses the finest mesh or trellis, thus the most fragile metal nets or trellises, because of their greater resistance to advancement in the layer of water. In order to allow the vessel to maintain a high speed, the pickup devices 23 of the third section 13 are movable in the opposite direction I of the direction D of the ship's movement. Thus, when the ship is traveling at a speed of 40 km / h, the speed of the pickup devices 13 can be 20 or 30 km / h in the opposite direction I, which reduces the effective speed of the movement of the pickup devices 20 or 10 km / h.
[0060] La troisième section 13 est beaucoup plus longue que la première et la deuxième section 11 , 12, car la réduction de la vitesse effective des dispositifs de ramassage doit permettre le traitement de la totalité des déchets arrivant dans cette troisième section 13, ce qui est rendu possible grâce à un nombre de dispositifs suffisant constituant un train se déplaçant constamment vers l'arrière du bassin 3, chaque dispositif 23 étant escamoté ou relevé au bout de sa course pour permettre la récupération des déchets et le retour du dispositif 23 à l'avant du train pour effectuer un nouveau cycle de ramassage. The third section 13 is much longer than the first and the second section 11, 12, because the reduction of the effective speed of the collection devices must allow the treatment of all the waste arriving in this area. third section 13, which is made possible by a sufficient number of devices constituting a train constantly moving towards the rear of the basin 3, each device 23 being retracted or raised at the end of its stroke to allow the recovery of waste and the return of the device 23 to the front of the train to perform a new collection cycle.
[0061] Le nombre de dispositifs 23 représentés dans cette figure ne sert que pour l'illustration. Dans la présente configuration, un train actif d'au moins quatre dispositifs sera nécessaire sur la longueur opérationnelle de bassin 3 du train. Si l'on tient compte du nombre de dispositifs passifs regagnant l'avant du train opérationnel, chaque train mobile devrait comprendre au total au moins huit à dix dispositifs, régulièrement espacés, et avantageusement douze à vingt dispositifs. The number of devices 23 shown in this figure is only used for illustration. In the present configuration, an active train of at least four devices will be required over the operational length of basin 3 of the train. If one takes into account the number of passive devices returning to the front of the operational train, each mobile train should comprise a total of at least eight to ten devices, regularly spaced, and preferably twelve to twenty devices.
[0062] La figure 3 est une vue d'un navire 1 selon l'invention en coupe horizontale. Les dispositifs de ramassage 21 , 22, 23 ne sont représentés que partiellement et de manière purement schématique. Figure 3 is a view of a vessel 1 according to the invention in horizontal section. The pickup devices 21, 22, 23 are shown only partially and purely schematically.
[0063] On voit les trois coques 2 du navire qui délimitent deux bassins 3 qui traversent le navire sur toute sa longueur. Les bassins 3 sont ouverts aux extrémités 6, 7 et sont divisés en trois sections de ramassage 11 , 12, 13. We see the three shells 2 of the ship which delimit two basins 3 which cross the ship over its entire length. The basins 3 are open at the ends 6, 7 and are divided into three collection sections 11, 12, 13.
[0064] La première section 11 dispose de dispositifs de ramassage 21 pour les plus gros déchets pouvant aller jusqu'à la taille d'un conteneur. [0065] Chaque section 11 , 12, 13 est équipée de cloisons longitudinales 31 , 32, 33. Les côtés des coques 2 et des cloisons 31 , 32, 33 servent de support pour les dispositifs 21, 22, 23 de chaque section 11 , 12, 13 du navire. Ces supports peuvent être des coulisseaux mobiles actionnés par treuils et câbles, des moyens hydrauliques, hydropneumatiques ou autres, ou des bras oscillants, articulés, télescopiques, ou toute autre technique permettant la mobilité horizontale et/ou verticale des dispositifs de ramassage de déchets requise. The first section 11 has collecting devices 21 for the largest waste up to the size of a container. Each section 11, 12, 13 is equipped with longitudinal partitions 31, 32, 33. The sides of the shells 2 and partitions 31, 32, 33 serve as a support for the devices 21, 22, 23 of each section 11, 12, 13 of the ship. These supports may be mobile sliders actuated by winches and cables, hydraulic, hydropneumatic or other means, or oscillating arms, articulated, telescopic, or any other technique for horizontal mobility and / or vertical waste collection devices required.
[0066] Les cloisons longitudinales 31 , 32, 33 sont fixées sur des supports qui les rendent amovibles et déplaçables latéralement, afin de pouvoir en augmenter ou en réduire le nombre, afin de pouvoir augmenter ou réduire leur écartement, ou pour permettre l'installation de dispositifs de ramassage différents ou plus évolués. La possibilité d'enlever ou de ranger les cloisons temporairement pour obtenir un grand bassin ou de les agencer différemment, permet d'utiliser le navire aussi pour d'autres applications. Le navire pourrait par exemple être converti en navire d'aquaculture. The longitudinal partitions 31, 32, 33 are fixed on supports that make them removable and laterally movable, in order to increase or reduce the number, in order to increase or reduce their spacing, or to allow the installation of different or more advanced collection devices. The possibility of temporarily removing or storing the bulkheads to obtain a large pond or to arrange them differently makes it possible to use the ship also for other applications. For example, the vessel could be converted to an aquaculture vessel.
[0067] En deuxième section 12, les cloisons longitudinales 32 sont plus nombreuses, plus fines et plus rapprochées, pour servir de supports à des dispositifs de ramassage dont les mailles plus fines et moins solides, supporteraient difficilement une grande largeur de ramassage. Les contraintes plus importantes dues à l'augmentation de la résistance à l'avancement des dispositifs de ramassage 22 impliquent donc des dispositifs de ramassage 22 moins larges pour disposer d'une solidité suffisante. In the second section 12, the longitudinal partitions 32 are more numerous, finer and closer, to serve as supports for pickup devices whose mesh finer and less solid, hardly withstand a large pickup width. The greater constraints due to the increase in the running resistance of the pickup devices 22 therefore imply pickup devices 22 less wide to have sufficient strength.
[0068] La troisième section 13 comprend un nombre de cloisons 33 supportant les dispositifs de ramassage 23 encore plus important que la deuxième section 12. The third section 13 comprises a number of partitions 33 supporting the collection devices 23 even more important than the second section 12.
[0069] Les dispositifs de ramassage 23 de la troisième section 13 sont mobiles dans le sens inverse I de la direction de déplacement D du navire comme déjà décrit précédemment. The pickup devices 23 of the third section 13 are movable in the opposite direction I of the displacement direction D of the vessel as already described above.
