    Storage system for petroleum material and / or products
    petroleum and oil derivatives provided with said system
    DESCRIPTION 5

    OBJECT OF THE INVENTION

    The purpose of this application is to register a storage system for petroleum material and / or petroleum products, in particular intended to be incorporated into a ship for transporting crude oil and / or petroleum products based on employment. of a plurality of bags of material suitable for this type of load, which are in fluid communication and coupled to each other in a removable manner, so that each bag can be in turn independent of the rest of the bags.
     fifteen
    BACKGROUND OF THE INVENTION

    The transportation of oil or products derived from it, which are potentially polluting, from the port of origin to the destination over long distances, is carried out by large-capacity vessels, with cargo tanks with volume to store large quantities. of product so that they can transport as much product as possible in a single trip. This leads to an increase in the risk of spillage, with the consequent problems of environmental pollution, in case of hull breakage or sinking of the ship.
     25
    To eliminate or reduce this risk as much as possible, all oil tankers currently have a double hull that has undoubtedly reduced the number of tons discharged. However, in addition to the high cost and the significant reduction in load capacity, this solution does not guarantee that, in the event of a very violent collision, the double wrap resists enough to prevent subsequent spillage, either because it has also been 30 damaged with the impact this second wrap or that the loss of structural resistance in that area weakens the vessel to the point that the hull breaks.

    Therefore, there is still a need to find an economically viable solution, of simple manufacture and assembly on ships that reduces the risk of oil spillage in the case of an oil tanker accident and allows a better recovery of the load.

    In addition, the applicant is not currently aware of an invention that has all the features described herein.

    DESCRIPTION OF THE INVENTION 5

    The present invention has been developed in order to provide a storage system for petroleum material and / or petroleum products that is configured as a novelty within the field of application and resolves the aforementioned drawbacks, also providing other advantages. additional that will be evident from the description that follows.

    It is therefore an object of the present invention to provide a storage system for petroleum material and / or petroleum products, in particular intended to be incorporated into a ship for transporting crude oil and / or petroleum products and preventing Possible contamination from oil or hydrocarbon spills, as well as facilitating a possible recovery thereof, for example, in case of partial or total sinking of an oil tanker.

    In particular, the invention is characterized by the fact that it comprises a plurality of 20 foldable bags of flexible material, which are arranged stacked on top of each other, capable of being deployed in a condition of use for containing in its interior raw and / or petroleum products, bags adjacent to each other in fluid communication through valve means present in each of the bags to allow or restrict fluid communication between adjacent bags, in which at least one of the bags is provided with an inlet and / or outlet of the product to be stored, and at least one of the bags being linked with heating means to keep the inside of the bag at a predetermined temperature.

    Thanks to these characteristics, a simple manufacturing and utilization storage medium is obtained that aims to prevent the spillage of oil or materials derived from it in the event of a maritime accident, especially in the case of tankers, so that in the case of breakage from the tanker's hull, the spillage of the product stored directly at sea is avoided.
     35
    The arrangement of the valve means in each of the foldable bags provides a degree of independence for each of the bags, so that in the case of a leak or breakage of one of them, the rest of the bags can be sealed and isolated, so that the volume of product discharged to the outside is reduced and its recovery is facilitated by leaving the cargo to be transported compartmentalized and isolated. 5

    The arrangement of the heating means mounted on the bags is an important factor in the transport of crude oil, since it has to be in a temperature range between 20-100 ° C to have a viscosity value suitable for loading operations and product download for easy handling. Since the bags do not have a static structure but suffer variations in shape depending on the volume contained, or if they are completely emptied, the usual heating systems present in the tanker tanks, such as steam pipes located in the tank, cannot be used. Inside the warehouses or storage tanks of the ship. fifteen

    In one embodiment, each of the folding bags is linked to independent heating means.

    According to an embodiment of the invention, the heating means comprise at least one heat resistance disposed at a point on the inner face of the body that defines a bag.

    Additionally, at least one of the bags includes gas extraction means to extract gases present inside the bags when they are full of the product to be stored as well as to form the vacuum inside the bags when they are empty. Mention that other means can be used for the vacuum operation, such as for example the oil insertion / extraction valves.

    In this way, it is achieved that only 30 liquid hydrocarbons are available inside the bags without vapors and, consequently, oxygen inside. In the absence of oxygen inside the bags, the risk of explosion or accidental combustion is reduced, thus eliminating one of the factors that can cause an accident to a ship.

    Preferably, the bags may be made of HDPE material, capable of withstanding a pressure of 5 MPa at a temperature of approximately 100 ° C.

    According to another aspect of the present invention, the foldable bags are located in a support structure provided with fastening means, such that each of the bags 5 is releasably fixed in the support structure. In this way, the correct deployment is also ensured when the cargo is introduced and its correct folding when said cargo is removed from the ship.

    Preferably, the fastening means comprise a tape coupled to a respective bag 10, which includes a guide element linked to a guide that is part of the guiding means.

    According to another characteristic, the guiding means are linked to remote control means to lock / release the fastening means with respect to the guiding means, 15 so that the deployment of the bags in an orderly and controlled manner is thus guaranteed. as unwanted movements.

    Advantageously, the support structure includes guiding means to guide a vertical displacement of the bags that also prevents unwanted movements of the 20 bags when they are empty or partially filled.

    Additionally, the system of the invention can comprise pressure sensing means to detect the pressure of the product stored inside the bags, so that the condition of the bags is controlled in a condition of use, thus reducing the risk. of breakage of any of the bags.

    According to a preference, such detection means comprise a pressure sensor located on the inner and / or outer face of the lowermost bag.
     30
    Also preferably, the valve means comprise at least one valve present in an opening located in the body of the bag.

    In one embodiment, each of the valves is comprised of a discoidal body that includes closing and / or sealing means that are linked with means of sealing.
    releasable joint to be coupled to another complementary and adjacent valve, such that the body of a valve is coupled and / or released from a facing valve that is part of an adjacent bag.

    In a preferred embodiment, the closing and / or sealing means comprise a plurality of blades located in the same plane, the blades being related to the liberal joining means.

    These releasable connection means can be comprised of male sections of a valve of a bag, guided in female sections of a valve of a bag adjacent to it.

    According to an embodiment of the invention, the male section can be defined by a mushroom-shaped element that slides in a respective groove.
     fifteen
    Preferably, the valve means are remotely operable, such that the valve means is connected to a remote control unit to act on the valve closing and / or sealing means.

    Advantageously, the bags can include joining means such that adjacent bags 20 can be joined together during application or operation, so that they can favor the swelling of the bags when they are filled with the product to be stored.

    A non-limiting example of these joining means consists of velcro bands located in 25 opposite regions of the outer face of the adjacent bags.

    It is another object of the present invention to provide a tanker comprising a ship hull provided with a plurality of tanks for the storage of petroleum and / or petroleum products, characterized by the fact that it includes at least one of its tanks the storage system described above.

    Other features and advantages of the table object of the present invention will be apparent from the description of a preferred but not exclusive embodiment, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

    DESCRIPTION OF A PREFERRED EMBODIMENT

    In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.

    The storage system is intended to store petroleum material and / or petroleum products, in particular intended to be incorporated into storage tanks present in the hull of an oil transport vessel and / or products derived therefrom.

    As can be seen in figures 1 and 2, this system comprises a plurality of folding bags (1) made of flexible material, such as HDPE (high density polyethylene) which are arranged in a row one on top of the other, in the inside a receptacle (10) (such as a storage tank), capable of deploying or expanding in a vertical direction or perpendicular to the base of the receptacle (10) in a condition of use to contain oil inside and / or products derived therefrom. The bags (1) that are adjacent to each other are in
    fluid communication through valve means that will be explained later, and referenced in general with the numerical reference (2).

    Preferably, the bag (1) that is located in the lower part of the row is provided with an inlet and / or outlet (3) of the product to be stored. 5

    Each of the bags (1) comprises a heat resistance (4) that allows the contents inside the bag to be maintained at a predetermined temperature, for example, between 50-100 ° C, being made of flexible material (i.e. susceptible deforming during the operation of expansion or contraction of the bag) which is arranged at a point on the inner face of the body that defines a bag (1).

    The bag (1) that is located at the top of the row includes means for extracting gases to extract vapors from hydrocarbons due to a volatilization process as well as the extraction of gases that may have accumulated inside 15 the bag, depending on its formation and quantity of the temperature, the vapor pressure according to the hydrocarbon class and the difference in concentration that exists between the liquid and gas states of the compound to be transported. In this case, such extraction means consist of a conduit (5) provided with a system with inert gas. This duct (5) may be subject to a guiding means and may have elastic properties, 20 or extensible sections of accordion type, since the difference in height that exists when the bags are empty and when they are full must be taken into account. In this case, an example of guiding means is that constituted by a pulley (6) from which a cable (7) extends which is coupled to the conduit (5). It will be apparent to those skilled in the art that other known guiding means could be used. 25

    The bags (1) are located in a support structure, such as plates (8) that adapt to the walls of the storage tanks (10), each of the plates (8) being provided with fastening means, by for example, sliding elements (9) (also occasionally referred to herein as "guide element"), such that each of the bags (1) is releasably fixed in the support structure.

    The support structure explained above may include guiding means, such as a rail or sliding system located in the plates (8) that facilitate guiding during the vertical movement of the bags (1) as they are filled, so 35
    that the slide elements (9), for example, elements with a T-shaped profile or the like, can be moved or slid vertically according to needs. Mention that the rails may include means for limiting travel or stop (not shown) that allow restricting the vertical movement of the bags (1) during a filling stage thereof. The bags can be released from the rails by means of a release system in which parts of the rails can be opened to release the sliding element (9).

    Returning again to the aforementioned valve means (2), they comprise at least one valve present in an opening located in the body of the bag. As shown in FIGS. 3a-3c, each of the valves is comprised of a discoidal body (20) that includes closing and / or sealing means (detailed below) that are linked to means of releasable joint, so that the body of a valve is coupled and / or released from a facing valve that is part of an adjacent bag. In this case, the closing and / or sealing means comprise a plurality of mobile blades (21) that adopt a radial configuration (as can be seen in Figure 3c) that can be moved by means of a gear (not shown), located in the same plane, the mobile blades (21) being related to the liberal joining means.
     twenty
    With particular reference now to the releasable joining means, they comprise male sections of a valve of a bag, radially distributed that protrude from one of the faces of the discoidal body (20), being guided in female sections of a valve of a bag adjacent to it.
     25
    As can be seen, each of the male sections is defined by a mushroom-shaped element (22) that slides in a respective groove (23) with an arcuate path for coupling between valves (2) in an operative condition.

    Between valves facing each other provides a seal or sealing material 30 (not shown).

    Each of the valves (2) can be electrically operated, so that the gear is electrically connected through cable connections (not shown) with a remote control unit that allows to lock and / or unlock the device.
    step (24) present in the valve body (2) through which the material stored in the bags (1) circulates.

    For the system to function properly and prevent the bags located in the lower part from breaking due to excess pressure, the tank must be filled with water, so that the pressure on the fabric of the bag can be compensated by the hydrostatic water pressure. Another advantage of filling the tank with water, reduces the free surface area in the storage tank (10), improving the stability of the vessel.

    To detect the pressure of the product stored inside the bags and consequently, the tensions that the bags are supporting (1), a pressure sensor (11) located on the inner face of the lower bag is provided.

    To limit the total height of the bags, there have also been included some ratchets (12) that surround the set of inflatable bags (1). fifteen

    The details, shapes, dimensions and other accessory elements used in the manufacture of the various components that are part of the system of the invention may be conveniently substituted by others that do not depart from the scope defined by the claims included below. . twenty
