Description

NAVIRE PORTE-CONTENEURS AUTONOME AUTONOMOUS CONTAINER SHIP
L' invention concerne un navire porte-conteneurs autonome permettant d'assurer le transport de conteneurs des ports importants équipés de moyens de chargement et de déchargement à des petits ports dépourvus de tels équipements.The invention relates to an autonomous container ship making it possible to transport containers from large ports equipped with loading and unloading means to small ports without such equipment.
Plus particulièrement, l'invention concerne une gamme de petits et moyens navires permettant d'assurer le transport de marchandises de petits ports en petits ports au moyen de conteneurs. Cette gamme est composée de navires permettant de transporter un nombre maximum de conteneurs égal à deux, quatre, dix, vingt, trente, cinquante, cent.More particularly, the invention relates to a range of small and medium-sized vessels making it possible to transport goods from small ports to small ports by means of containers. This range is made up of ships allowing to transport a maximum number of containers equal to two, four, ten, twenty, thirty, fifty, one hundred.
Une caractéristique principale du navire est son entière autonomie offrant la possibilité de charger ou/et décharger des conteneurs dans un port non équipé de moyens de manutention et ayant une profondeur d'eau faible, inférieure à 4 mètres.A main characteristic of the ship is its full autonomy, offering the possibility of loading or / and unloading containers in a port not equipped with handling means and having a shallow water depth, less than 4 meters.
Le transport de marchandises constitue, en effet, un des rouages majeurs de notre économie de marché. La globalisation des échanges internationaux, le développement des politiques de "juste à temps", la demande de réactivité toujours plus forte, tendent à accroître en permanence les transports terrestres, à développer des infrastructures routières coûteuses et nuisibles à 1 ' environnement.The transport of goods constitutes, in fact, one of the major cogs of our market economy. The globalization of international trade, the development of "just-in-time" policies, the ever-increasing demand for responsiveness, tend to constantly increase land transport, to develop costly and environmentally damaging road infrastructure.
La gamme de navires selon 1 ' invention est née de cette analyse avec le souci de développer une complémentarité entre le transport routier et le transport maritimo-fluvial.The range of ships according to the invention was born from this analysis with the aim of developing a complementarity between road transport and maritime-river transport.
Il s'agit d'assurer, à partir des ports de premier ou de deuxième rang, des liaisons maritimes pour desservir la multitude de ports d'irrigation, peu ou pas exploités en matière de transport de marchandises.It is a question of ensuring, starting from the ports of first or second row, maritime connections to serve the multitude of irrigation ports, little or not exploited as regards transport of goods.
La finalité est la prise en charge par les transporteurs routiers des conteneurs à partir de ces ports pour distribution locale, afin d'optimiser les distances terrestres de livraison. Un des objectifs de la présente invention est de mettre au service du transporteur routier une infrastructure mobile "autoroute maritimo-fluviale" complémentaire à celle dont il dispose sur le réseau routier. Un deuxième objectif est de renforcer la réactivité du transport maritimo-routier en acheminant des petites quantités avec des fréquences importantes.The aim is for road carriers to take charge of containers from these ports for local distribution, in order to optimize land delivery distances. One of the objectives of the present invention is to provide the road transporter with a mobile infrastructure "maritime-river highway" complementary to that which it has on the road network. A second objective is to strengthen the responsiveness of maritime-road transport by transporting small quantities with high frequencies.
Un troisième objectif est d'assurer un service fluviomaritime avec une autonomie de manoeuvre importante, un trajet quai à quai optimisé et des systèmes de déchargement/chargement adaptés à ces contraintes. Cet objectif implique de pouvoir transporter une charge utile importante par rapport au déplacement du navire.A third objective is to provide a sea-river service with considerable maneuvering autonomy, an optimized quay to quay journey and unloading / loading systems adapted to these constraints. This objective implies being able to transport a large payload in relation to the movement of the ship.
Un quatrième objectif est d'assurer le transport dans des conditions de service et de coûts au kilomètre comparables à ceux de la route.A fourth objective is to provide transport under conditions of service and cost per kilometer comparable to those of the road.
Il existe de nombreux navires porte-conteneurs d'une capacité d'emport de conteneurs importante et avec un tirant d'eau élevé, tels que ceux décrits dans Jane 's Intermodal Transportation, pages 315,338 et 341. Parmi ces navires porte-conteneurs de grande capacité, on peut citer l'ALIA CA BRASIL, d'une capacité de 2200 conteneurs, d'une vitesse de 20,4 noeuds, d'une longueur de 200,23 m et d'un tirant d'eau de 12,02 m.Un des plus petits de ces navires porte-conteneurs est le HERA, d'une capacité de 198 conteneurs, d'une vitesse de 12,5 noeuds, d'une longueur de 88 m et d'un tirant d'eau de 4,6 m.There are many container ships with a large container carrying capacity and with a high draft, such as those described in Jane's Intermodal Transportation, pages 315,338 and 341. Among these container ships of large capacity, we can cite the ALIA CA BRASIL, with a capacity of 2200 containers, a speed of 20.4 knots, a length of 200.23 m and a draft of 12, One of the smallest of these container ships is the HERA, with a capacity of 198 containers, a speed of 12.5 knots, a length of 88 m and a draft of 4.6 m.
Ces porte-conteneurs déchargent généralement dans des terminaux portuaires équipés d'importants moyens de manutention. Les ports pouvant recevoir les porte-conteneurs existants sont peu nombreux et ne permettent pas d'assurer une livraison des marchandises proche de leur lieu d'utilisation.These container ships generally unload in port terminals equipped with significant handling facilities. The ports that can accommodate existing container ships are few and do not allow delivery of goods close to their place of use.
Afin de répondre aux objectifs définis ci-dessus, l'invention a pour objet un navire porte-conteneurs autonome, du type comprenant une carène, des moyens de propulsion, des moyens de chargement et de déchargement, des moyens d'équilibrage, caractérisé en ce qu'il comprend des moyens permettant d ' assurer le transport de conteneurs des ports importants équipés de moyens de chargement et de déchargement des conteneurs à des petits ports dépourvus de tels équipements et ayant une profondeur d'eau inférieure à 4 mètres, ces moyens incluant des moyens de propulsion assurant à la fois la vitesse de croisière du navire en haute mer et la vitesse dans les estuaires et les ports , des moyens de chargement et de déchargement adaptés à des ports dépourvus d'équipement, des moyens d'équilibrage du navire en mer servant à la stabilité et l'assiette du navire pendant la manutention.In order to meet the objectives defined above, the subject of the invention is an autonomous container ship, of the type comprising a hull, propulsion means, loading and unloading means, balancing means, characterized in what he understands means making it possible to transport containers from major ports equipped with means of loading and unloading containers to small ports without such equipment and having a water depth of less than 4 meters, these means including propulsion means ensuring both the cruising speed of the ship on the high seas and the speed in estuaries and ports, means of loading and unloading adapted to ports without equipment, means of balancing the ship at sea serving for stability and the trim of the vessel during handling.
Ce navire est caractérisé, en outre, en ce qu'il comprend des moyens de propulsion permettant d'assurer la manoeuvrabilité dans les ports. De plus, le navire selon l'invention permet de transporter une charge utile importante par rapport à son déplacement. Ce but est atteint grâce à des équipements assurant une énergie commune pour la propulsion et la manutention et des moyens de manutention servant à la fois sur le navire et à terre.This vessel is further characterized in that it comprises propulsion means making it possible to ensure maneuverability in ports. In addition, the ship according to the invention makes it possible to transport a large payload relative to its displacement. This goal is achieved thanks to equipment ensuring a common energy for propulsion and handling and handling means serving both on the ship and ashore.
La gamme de navires selon 1 ' invention comprend des navires pouvant transporter 2,4,10,20,30,50 et 100 conteneurs .The range of ships according to the invention includes ships capable of transporting 2,4,10,20,30,50 and 100 containers.
Les conteneurs sont de deux tailles: -conteneurs de 20 pieds (6,058x2,438x2,591 mètres)The containers are of two sizes: -20 feet containers (6.058x2.438x2.591 meters)
-conteneurs de 40 pieds (12,116x2,438x2,591 mètres). Le tonnage de la gamme de navires selon 1 ' invention est mentionné dans le tableau ci-dessous:-40 feet containers (12,116x2,438x2,591 meters). The tonnage of the range of vessels according to the invention is mentioned in the table below:

Container handling can be carried out using a crane, gantry crane, forklift or container trolley.
Les moyens d'équilibrage du navire peuvent être constitués par un système asservi de ballastage au moyen de pompes qui assure le déplacement d'eau dans le navire de ballast en ballast pour compenser la gîte ou l'assiette.The balancing means of the ship can be constituted by a controlled ballast system by means of pumps which ensures the displacement of water in the ballast ballast ship to compensate for the list or the trim.
Les moyens d'équilibrage peuvent être constitués par un système de bouées gonflables; ces bouées gonflables peuvent être intégrées sur le côté du navire pour augmenter 1 ' inertie de flottaison et limiter ainsi la gîte et l'assiette du navire lors des opérations de manutention.The balancing means can be constituted by a system of inflatable buoys; these inflatable buoys can be integrated on the side of the ship to increase inertia flotation and thus limit the heel and trim of the ship during handling operations.
Les moyens d'équilibrage peuvent encore être constitués par un système de transfert de masses solides. Une masse solide se déplace dans le navire pour compenser le déplacement de la masse des conteneurs lors des opérations de manutention.The balancing means can also be constituted by a solid mass transfer system. A solid mass moves in the ship to compensate for the displacement of the mass of the containers during handling operations.
Une combinaison de ces différentes caractéristiques permet d'obtenir un principe architectural pour la gamme de navires.A combination of these different characteristics provides an architectural principle for the range of ships.
