Description

La présente invention a pour objet un dispositif de transport maritime pour du vrac liquide, ou se comportant comme du liquide, dans au moins une cale d'un bateau de transport essentiellement fluvial, tel qu'une péniche.The present invention relates to a maritime transport device for liquid bulk, or behaving like liquid, in at least one hold of an essentially river transport boat, such as a barge.

Le secteur technique de l'invention est celui de la construction navale et plus particulièrement des coques et des cales de navires de transport fluvial pour le vrac liquide. On notera qu'on appelle « vrac » tout produit transporté directement dans la cale d'un navire ou dans les aménagements prévus à cet effet, intégrés et portés par le navire.The technical sector of the invention is that of shipbuilding and more particularly hulls and holds of river transport vessels for liquid bulk. It should be noted that "bulk" is any product transported directly in the hold of a ship or in the facilities provided for that purpose, integrated and carried by the vessel.

On désignera également dans toute la présente description, et les revendications, « vrac liquide » toute cargaison non seulement liquide mais aussi se comportant comme un liquide tels que par exemple les produits pulvérulents.Also referred to throughout the present description, and claims, "liquid bulk" any cargo not only liquid but also behaving like a liquid such as for example the powdery products.

Actuellement, le transport de vrac sous forme liquide, notamment dans le cas de navires de navigation intérieure, s'effectue par des unités de transports dédiées à ce type de marchandises et généralement appelées « péniches citernes ».At present, the transport of bulk liquids, particularly in the case of inland navigation vessels, is carried out by transport units dedicated to this type of cargo and generally referred to as "tank barges".

Ces unités fluviales sont spécialement aménagées ou construites pour ce type de trafic et ne présentent ainsi aucune flexibilité pour s'adapter à d'autres trafics ; de plus leur aménagement, pour ce transport de vrac liquide, est constitué de cuves en acier, en particulier inoxydable, qui sont lourdes et limitent d'autant la charge utile transportée, ce qui rend une démarche de développement durable dans le transport fluvial peu adapté, voire même impossible. Par ailleurs le cout de telles unités dédiées au seul transport de vrac liquide impose, pour en amortir le lourd investissement, un engagement réciproque entre le transporteur et ses clients, en fait en général un seul, sur de longues périodes, ce qui en freine de développement.These river units are specially designed or built for this type of traffic and thus have no flexibility to adapt to other traffic; moreover their arrangement, for this transport of liquid bulk, consists of steel tanks, in particular stainless, which are heavy and limit all the transported payload, which makes a sustainable development approach in the unsuitable river transport , even impossible. otherwise the cost of such units dedicated solely to the transport of liquid bulk imposes, in order to amortize the heavy investment, a reciprocal commitment between the carrier and its customers, in fact generally only one, over long periods, which hinders their development.

A titre d'illustration de ce frein, on peut citer qu'en 2011, s'il y avait en France 860 péniches automotrices et 382 barges pour les marchandises générales (et respectivement 5889 et 3537 en Europe), il n'y avait que 40 péniches automotrices et 47 barges pour le vrac liquide (et respectivement 1676 et 118 en Europe).As an illustration of this brake, we can mention that in 2011, if there were 860 self-propelled barges and 382 barges for general cargo in France (and 5889 and 3537 respectively in Europe), there was only 40 self-propelled barges and 47 barges for liquid bulk (and respectively 1676 and 118 in Europe).

Ainsi le problème posé est, d'une part, de permettre d'utiliser, pour transporter du vrac liquide, des navires non spécifiquement dédiés à ce type de transport comme à ce jour, et, d'autre part, de réduire aussi bien le poids des équipements nécessaires pour un tel transport (ce qui permet d'augmenter le port en lourd du navire considéré) que le cout de ces équipements.Thus the problem is, on the one hand, to allow the use, for the transport of liquid bulk, of vessels not specifically dedicated to this type of transport as to date, and, on the other hand, to reduce both the weight of the equipment necessary for such transport (which makes it possible to increase the deadweight of the vessel in question) than the cost of this equipment.

Par ailleurs on connait des dispositifs de vessies souples utilisés dans le transport maritime pour recouvrir l'intérieur des réservoirs rigides contenant du pétrole afin de protéger l'environnement en cas d'avarie lors de rupture de la coque et des parois des réservoirs: en effet en ce cas le pétrole est maintenu dans le navire par les vessies souples, ne peut pas s'échapper de la coque endommagée et ne pollue donc pas l'environnement.Moreover, there are known flexible bladder devices used in shipping to cover the interior of rigid tanks containing oil to protect the environment in case of damage during rupture of the hull and the walls of the tanks: indeed in this case the oil is kept in the ship by the flexible bladders, can not escape the damaged hull and therefore does not pollute the environment.

On peut citer par exemple dans ce cadre la demande de brevet US5271350 qui décrit un système contre le débordement de pétrole, et/ou de cargaisons semblables, transporté dans un navire citerne, lors d'impact à haute energie contre la coque du navire pouvant provoquer la déchirure de celle-ci: le système comporte pour cela des modules de réservoirs souples dont les parois sont faites de matériel flexible de force suffisante pour résister à la rupture lors d'un tel impact, et les parois de chaque module flexible sont elle-même doublées et contiennent de l'air sous pression ou autre fluide formant amortisseur. Le document US 5503291 A1 décrit un dispositif de transport maritime pour du vrac liquide avec parois souples et une cloison fixe.For example, in this context, the patent application US5271350 which describes a system against the overflow of oil, and / or similar cargoes, carried in a tanker, during a high-energy impact against the hull of the vessel which may cause the vessel to tear: the system comprises for that purpose flexible tank modules whose walls are made of flexible material of sufficient strength to withstand breaking during such an impact, and the walls of each flexible module are themselves doubled and contain air under pressure or other fluid forming damper. The document US 5503291 A1 describes a maritime transport device for liquid bulk with flexible walls and a fixed partition.

Ainsi une solution au problème posé ci-dessus est un nouveau dispositif de transport maritime combinant certaines techniques connues, tels que d'une part des cuves ou compartiments comme dans les péniches citernes, mais constituées différemment comme décrit ci-aprés pour permettre notamment l'adaptation de coques de bateaux existants utilisés dans d'autre type de transports fluviaux internes, et d'autre part l'utilisation de vessies souples (connues par ailleurs comme indiqué précédemment mais pour des applications et des objectifs différents) comme moyens pour contenir le vrac liquide.Thus, a solution to the problem posed above is a new maritime transport device combining certain known techniques, such as on the one hand tanks or compartments as in the tank barges, but differently constituted as described below to allow in particular the adaptation of existing hulls used in other types of inland waterway transport, and secondly the use of flexible bladders (otherwise known as previously but for different purposes and purposes) as means for containing bulk liquid.

L'objectif de la présente invention est ainsi atteint avec un dispositif de transport maritime pour du vrac liquide dans au moins une cale définie par une paroi de fond et des parois latérales périphériques, ouverte à sa partie supérieure, d'un bateau de transport et comportant des cuves disposées dans ladite cale et aptes à recevoir le vrac liquide : selon l'invention le dispositif comporte au moins une cloison démontable apte à diviser la au moins cale en au moins deux réceptacles et lesdites cuves sont des réservoirs à parois souples aptes à être positionnés et à occuper la totalité du volume de chaque réceptacle, les parois inférieures et périphériques de ces réservoirs souples étant aptes à venir en appui d'une part contre les parois de fond et latérales périphériques de la cale et d'autre part contre celles de la au moins cloison démontable.The object of the present invention is thus achieved with a maritime transport device for liquid bulk in at least one wedge defined by a bottom wall and peripheral side walls, open at its upper part, of a transport boat and comprising tanks disposed in said hold and adapted to receive the liquid bulk: according to the invention the device comprises at least one demountable partition capable of dividing the at least one wedge into at least two receptacles and said tanks are flexible-walled tanks adapted to to be positioned and to occupy the entire volume of each receptacle, the lower and peripheral walls of these flexible tanks being able to bear on the one hand against the peripheral bottom and side walls of the hold and secondly against those from the at least demountable partition.

Dans un mode préférentiel de réalisation le dispositif comporte plusieurs cloisons démontables aptes à diviser la au moins cale en réceptacles de largeur au plus égale à la moitié de la largeur de cette cale et de longueur au plus égale à la moitié de la longueur de cette cale : ainsi on peut diviser une grande cale en plusieurs réceptacles, ce qui d'une part réduit le problème de carènes liquides très critique pour la stabilité du navire, et d'autre part permet de transporter simultanément plusieurs produits différents.In a preferred embodiment, the device comprises several demountable partitions capable of to divide the at least wedge into receptacles of width at most equal to half the width of this wedge and of length at most equal to half the length of this wedge: thus one can divide a large wedge into several receptacles, this which on the one hand reduces the problem of liquid hulls very critical for the stability of the ship, and on the other hand makes it possible to simultaneously transport several different products.

Dans un mode particulier de réalisation, l'ensemble des réservoirs souples sont reliés à un réseau de transfert disposé à bord du moyen de transport maritime et qui comporte au moins une canne de pompage pour chaque réservoir souple, au moins un groupe pompe pour chaque réservoir souple et au moins un collecteur reliant l'ensemble des cannes de pompage des réservoirs souples.In a particular embodiment, all of the flexible tanks are connected to a transfer network disposed on board the maritime transport means and which comprises at least one pump rod for each flexible tank, at least one pump unit for each tank flexible and at least one manifold connecting all the pump rods of the flexible tanks.

Un tel réseau de transfert embarqué, et qui est également montable et démontable facilement, permet de rendre les navires ou péniches autonomes (pour le chargement et déchargement du vrac liquide) comme les navires dédiés à ce jour alors que les navires et péniches de transport d'autres marchandises ne le sont pas et nécessitent un équipement de manutention à quai.Such an on-board transfer network, which is also easy to mount and dismantle, makes ships or barges autonomous (for the loading and unloading of liquid bulk) as the ships dedicated to date while the ships and barges of other goods are not and require handling equipment at the dock.

Et l'extrémité distale de chaque canne de pompage, formant crépine et positionnée près du fond du réservoir souple considéré, supporte une plaque de protection apte à reposer au fond du réservoir souple, maintenant l'extrémité distale au plus près de ce fond et d'une surface suffisante pour éviter des risques d'aspiration du tissu souple du réservoir lors du pompage.And the distal end of each pump rod, forming a strainer and positioned near the bottom of the flexible tank considered, supports a protective plate adapted to rest at the bottom of the bladder, maintaining the distal end closest to the bottom and d a sufficient surface to avoid the risk of suction of the flexible fabric of the tank during pumping.

Une autre solution au problème posé est un bateau de transport fluvial comportant au moins une cale ouverte à sa partie supérieure et dans laquelle est disposée au moins une cuve apte à recevoir ledit vrac liquide, laquelle au moins cuve est réalisée suivant un dispositif disposé dans la structure de la cale et selon les caractéristiques citées ci-dessus et décrites plus en détail dans la description suivante et les figures jointes.Another solution to the problem is a river transport boat having at least one block open at its upper part and in which is disposed at least one vessel adapted to receive said liquid bulk, which at least one tank is made according to a device disposed in the structure of the hold and according to the characteristics mentioned above and described in more detail in the following description and the accompanying figures.

Le résultat est un nouveau dispositif de transport maritime qui répond au problème posé car la combinaison de cloisons démontables et de réservoirs à parois souples permet d'équiper tout navire existant, non spécifiquement dédiés au transport de vrac liquide, pour le rendre apte à transporter un tel vrac, et cela d'une manière réversible : ainsi son armateur peut alors alterner le type de transport suivant la demande de ses clients, entre d'un côté le vrac liquide et d'un autre coté les autres types de marchandises non liquides, et de s'adapter à cette demande, ce qui permettra de dynamiser le transport de vrac liquide, en particulier fluvial.The result is a new maritime transport system that responds to the problem posed because the combination of demountable partitions and flexible-walled tanks makes it possible to equip any existing ship, not specifically dedicated to the transport of liquid bulk, to make it suitable for transporting a ship. such bulk, and this in a reversible manner: thus his shipowner can then alternate the type of transport according to the demand of his customers, between on the one hand the liquid bulk and on the other hand the other types of non-liquid goods, and to adapt to this demand, which will make it possible to boost the transport of liquid bulk, in particular fluvial.

Par ailleurs un tel dispositif réversible est non seulement d'un investissement réduit et d'une mise en oeuvre rapide, mais aussi d'un poids réduit (par rapport aux équipements nécessaires actuels pour un tel transport avec des cuves fixes en acier ou inox) ce qui permet d'augmenter le port en lourd du navire considéré.Moreover, such a reversible device is not only a reduced investment and a quick implementation, but also a reduced weight (compared to the current equipment required for such transport with fixed tanks steel or stainless steel) which makes it possible to increase the deadweight of the considered ship.

La présente invention d'une part répond bien ainsi au problème posé et d'autre part présente de nombreux avantages tels qu'évoqués ci-dessus et repris ci-après, et qui en prouvent l'intérêt. La description et les figures ci-jointes en donnent un exemple de réalisation mais d'autres modes de réalisation sont possibles dans le cadre de la portée de la présente invention.

Suivant la représentation des figures, le dispositif de transport maritime pour du vrac liquide 14 dans au moins une cale 13 d'un bateau de transport 12, ouverte à sa partie supérieure, et définie par une paroi de fond 31 et des parois latérales périphériques 32, comporte d'une manière connue des cuves 5 disposées dans ladite cale 13 et aptes à recevoir le vrac liquide 14.Next the representation of the figures, the shipping device for liquid bulk 14 in at least one wedge 13 of a transport vessel 12, open at its upper part and defined by a bottom wall 3 1 and peripheral side walls 3 2 , comprises in a known manner tanks 5 disposed in said shim 13 and adapted to receive the liquid bulk 14.

Il peut être également réalisé des réservoirs ou cuves 5 sur mesure et en ce cas leur nombre et leurs dimensions sont déterminés en fonction de ce que les fabricants peuvent réaliser, des restrictions techniques sur les dimensions et la forme des réservoirs souples eux-mêmes, des risques de carène liquide en navigation et du ballant lors du chargement/déchargement, des calculs de stabilité correspondant, de la nature et de la réglementation concernant le produit liquide, de la taille et de la forme de la cale 13 du navire 13 ou de la péniche considéré...It can be used tanks or flexible tanks existing on the market, made of materials called fabrics based on PVC, PES, Polyester, nitrile ... adapted to different types of liquid bulk: in this case the dimensions of the receptacles are determined 13 1 so that they are adapted to these "standard" tanks. Custom-made tanks or tanks can also be made and in this case their number and dimensions are determined according to what the manufacturers can achieve, technical restrictions on the dimensions and shape of the flexible tanks themselves, the risk of free surface hulls in navigation and of the balloon during loading / unloading, the corresponding stability calculations, the nature and regulations concerning the liquid product, the size and shape of the hold 13 of the vessel 13 or the houseboat considered ...

Tels que représenté, plusieurs cloisons démontables 6 sont aptes à diviser la au moins cale 13 en réceptacles 131 :

  • de largeur au plus égale à la moitié de la largeur de cette cale 13, soit ici suivant l'exemple des figures 1,3 et 4, ces réceptacles 131, étant au nombre de deux dans la largeur de la cale 13, sont donc de largeur égale à la moitié de la largeur de celle-ci,
  • et de longueur au plus égale à la moitié de la longueur de cette cale 13, soit ici suivant l'exemple des figures 4 et 5, ces réceptacles 131, étant au nombre de quatre dans la longueur de la cale 13, sont donc de largeur égale au quart de la longueur de celle-ci, mais ils pourraient aussi être de longueur différente les uns par rapport aux autres.
As shown, several removable partitions 6 are able to divide the at least shim 13 into receptacles 13 1 :
  • width at most equal to half the width of this shim 13, here here following the example of figures 1 , 3 and 4 these receptacles 13 1 being two in width of the shim 13, are therefore of width equal to half the width thereof,
  • and of length at most equal to half the length of this shim 13, here here following the example of Figures 4 and 5 these receptacles 13 1 , being four in length of the shim 13, are therefore equal to a quarter of the length thereof, but they could also be of different length relative to each other.

Afin de limiter l'impact des frottements des parois souples 51 des réservoirs 5 sur les parois latérales et de fond des réceptacles 131 ou compartiments, le dispositif comporte des nappes de tissus 4 anti-frottements aptes à être déposées entre d'une part les parois 31, 32 de la au moins cale 13 et des cloisons démontables 6 et d'autre part les parois souples 51 des réservoirs 5.In order to limit the impact of the friction of the flexible walls 5 1 of the tanks 5 on the walls lateral and bottom receptacles 13 1 or compartments, the device comprises anti-friction cloth plies 4 capable of being deposited between on the one hand the walls 3 1 , 3 2 of the at least wedge 13 and removable partitions 6 and on the other hand the flexible walls 5 1 of the tanks 5.

De même, compte tenu des tissus et matériaux souples actuellement disponibles sur le marché, il convient pour éviter l'usure de ceux-ci, qui constituent les parois souples 51, d'éviter la formation de plis lorsque les cuves ou réservoirs 5 sont vides et lors des phases de vidage ou remplissage : pour cela il faut maintenir leur forme et plusieurs procédés sont envisageables pour cela comme celui représenté sur les figures 2 et 3.Similarly, given the fabrics and flexible materials currently available on the market, it is advisable to avoid the wear of these, which constitute the flexible walls 5 1 , to avoid the formation of folds when the tanks or tanks 5 are empty and during the emptying or filling phases: for this it is necessary to maintain their shape and several processes are conceivable for this like that represented on the figures 2 and 3 .

Dans cette exemple de réalisation, non limitatif donc, des traverses 1 sont aptes à être glissées dans des fourreaux 2 situés à la partie supérieure des réservoirs souples 5 et venant en appui à leurs deux extrémités 11 sur les bords 132 de la au moins cale 13 de telle façon que ces traverses 1 maintiennent la forme et le volume du réservoir 5 souple considéré, que celui-ci soit plein ou vide.In this exemplary embodiment, which is therefore nonlimiting, crosspieces 1 are able to be slid into ducts 2 situated at the upper part of the flexible tanks 5 and bearing at their two ends 11 on the edges 13 2 of the at least shim 13 so that these cross members 1 maintain the shape and the volume of the flexible tank 5 considered, whether it is full or empty.

Dans une autre variante ou en complément, les réservoirs ou cuves 5 peuvent être remplis, quand ils ont vidés du vrac liquide, de gaz inerte ou neutre : toutefois cela implique une étanchéité parfaite, supérieure à celle nécessaire pour le vrac liquide, de l'ensemble du système (cuves réservoirs, canalisations, pompes, trous d'homme, évents ...).In another variant or in addition, the tanks or tanks 5 can be filled, when they have emptied liquid bulk, inert or neutral gas: however this implies a perfect seal, greater than that required for the liquid bulk, of the whole system (tanks tanks, pipes, pumps, manholes, vents ...).

Chaque cuve ou réservoir souple 5 peut en effet être aussi équipé, non représenté, d'un trou d'homme pour intervenir à l'intérieur (inspection, réparation, installation des cannes de pompage 15 décrites ci-après ...) et d'un évent permettant l'entrée d'air au vidage et son évacuation au remplissage par le vrac liquide 14.Each tank or flexible tank 5 can indeed also be equipped, not shown, with a manhole to intervene inside (inspection, repair, installation of the pump rods 15 described below). ...) and a vent allowing the entry of air to the dump and its evacuation at filling by the liquid bulk 14.

Par ailleurs suivant la réglementation, et le fait que les différents réservoirs 5 souples peuvent contenir, lors d'un même transport, des produits liquides ou pulvérulents incompatibles entre eux, l'étanchéité entre les compartiments ou réceptacles 131 peut être nécessaire pour confiner chaque produit dans son réceptacle en cas de fuite de son réservoir souple ; pour cela :

  • soit les liaisons entre les cloisons démontables 6 et les parois et le fond de la structure 3 de la cale 13 sont étanches,
  • soit, et suivant un mode préférentiel de réalisation non représenté sur les figures, chaque réceptacle 131 comporte un bac de rétention étanche, souple lui aussi, type « liner » comme utilisé dans certaines piscines, ou rigide, et dans lequel est disposé le réservoir souple 5,
  • soit toute autre solution peut être envisagée.
Furthermore according to the regulations, and the fact that the various flexible tanks may contain, during one and the same transport, liquid or powdery products incompatible with each other, the sealing between the compartments or containers 13 1 may be necessary to confine each produced in its receptacle in case of leakage of its bladder; for that :
  • either the connections between the demountable partitions 6 and the walls and the bottom of the structure 3 of the wedge 13 are sealed,
  • either, and according to a preferred embodiment not shown in the figures, each receptacle 13 1 comprises a sealed retention tray, also flexible, type "liner" as used in some pools, or rigid, and in which is disposed the reservoir flexible 5,
  • any other solution may be considered.

Les cloisons amovibles et démontables 6, qui ne doivent pas avoir d'aspérités et être résistantes, peuvent être fixées dans la cale 13 par différents systèmes dont le choix dépend de plusieurs critères comme la facilité de montage/démontage, la rigidité...Removable and removable partitions 6, which must not have any roughness and be strong, can be fixed in the shim 13 by various systems whose choice depends on several criteria such as ease of assembly / disassembly, rigidity ...

A titre d'exemple de réalisation et tel que représenté sur les figures 1 et 1A, le dispositif suivant l'invention peut comprendre des cornières 7 en forme de U, soudées sur le plancher du fond 31 de la cale 13 et de largeur correspondant à l'épaisseur des cloisons démontables 6, qui y sont glissées et maintenues.As an example of embodiment and as represented on the Figures 1 and 1A , the device according to the invention may comprise angles 7 U-shaped, welded to the bottom floor 3 1 of the shim 13 and width corresponding to the thickness of the removable partitions 6, which are slid and maintained.

Afin par ailleurs de s'adapter aux besoins du marché du transport fluvial, plusieurs approches pour le remplissage et la vidange des réservoirs souples 5 peuvent être envisagées, comme l'utilisation d'équipement existant à quai ou l'installation à bord du navire ou péniche d'un dispositif totalement autonome tel que représenté sur les figures 5 ou un mixte de ces deux solutions.In addition to adapting to the needs of the river transport market, several approaches for filling and emptying flexible tanks 5 can be envisaged, such as the use of equipment existing on the platform or the installation on board the vessel or barge of a totally autonomous device as figures 5 or a combination of these two solutions.

Dans le cadre de la solution embarqué et autonome, l'ensemble des réservoirs souples 5 sont reliés à un réseau de transfert disposé à bord du moyen de transport maritime 12 et qui comporte au moins une canne de pompage 15 pour chaque réservoir souple 5 et dont l'extrémité distale formant crépine 11 est positionnée près du fond du réservoir souple 5 considéré, au moins un groupe pompe 9 pour chaque réservoir souple 5 et au moins un collecteur 8 reliant l'ensemble des cannes de pompage 15 des réservoirs souples.As part of the embedded and autonomous solution, all the flexible tanks 5 are connected to a transfer network disposed on board the maritime transport means 12 and which comprises at least one pump rod 15 for each flexible tank 5 and whose the distal end forming strainer 11 is positioned near the bottom of the flexible reservoir 5 considered, at least one pump unit 9 for each flexible reservoir 5 and at least one manifold 8 connecting all the pump rods 15 of the flexible tanks.

Les cannes de pompage 15 peuvent être à poste dans les réservoirs 5 et démontables : elles sont suffisamment longues pour descendre au plus bas vers le fond du réservoir pour permettre de procéder à son vidage le plus complet possible ; pour cela l'extrémité distale 11 de chaque canne de pompage 15 supporte une plaque de protection 10 apte à reposer au fond du réservoir souple 5, maintenant l'extrémité distale 11 au plus près de ce fond et d'une surface suffisante pour éviter des risques d'aspiration du tissu souple du réservoir lors du pompage.The pump rods 15 can be stationed in the tanks 5 and removable: they are long enough to go down to the bottom of the tank to allow its emptying as complete as possible; for this the distal end 11 of each pump rod 15 supports a protective plate 10 adapted to rest at the bottom of the flexible reservoir 5, keeping the distal end 11 closer to the bottom and a sufficient surface to avoid risks of suction of the flexible fabric of the tank during pumping.

Le nombre et la capacité des groupes pompes 9 à installer à bord du navire ou péniche 12 dépendent de la nature des vracs liquide 14 et des débits souhaités ; ils sont munis de vannes de régulation et tout homme du métier est apte à définir les séquences de régulation (manuelle et/ou automatique), à choisir le type de ces groupes pompe, à y intégrer un dispositif d'amorçage, à en choisir la fonction (vidage et/ou remplissage), à établir le schéma du réseau de transfert et à en déterminer la tuyauterie nécessaire sans qu'il soit utile d'en préciser d'avantage dans la présente description.The number and capacity of the pump units 9 to be installed on board the vessel or barge 12 depend on the nature of the liquid bulk 14 and the desired flow rates; they are equipped with control valves and anyone skilled in the art is able to define the control sequences (manual and / or automatic), to choose the type of these pump units, to incorporate a priming device, to choose the function (emptying and / or filling), to establish the transfer network diagram and to determine the necessary piping without it being necessary to specify more in this description.

Dans le cas d'un navire ou péniche destiné à transporter un seul produit vrac liquide, on peut envisager un système de remplissage/vidage simplifié, par un seul réservoir souple 5 (ou quelques-uns selon le débit souhaité mais pas tous) et en reliant tous les réservoirs 5 par des conduits placés à leur base, de préférence dans un angle au fond de ces réservoirs ; et on assure un vidage optimum en jouant sur l'assiette et la gite du navire ou péniche.In the case of a ship or barge intended to carry a single liquid bulk product, it is possible to envisage a simplified filling / emptying system, by a single flexible tank 5 (or some depending on the desired flow rate but not all) and connecting all the tanks 5 by conduits placed at their base, preferably at an angle to the bottom of these tanks; and it ensures an optimal emptying by playing on the plate and the lodging of the ship or barge.
