The at least one container has two semi-spherical domes, an upper one and a lower one, that are closed at the base end and open at the other, the base of each containing a flat surface. Both domes are assembled with the open ends facing one another and are joined at the circular perimeter thereof by a fitting belt with securing device and a gasket, both being solidly joined together. Inside the container are disposed an upper structure and a lower structure that are solidly connected to connecting beams, defining a self-supporting cube-shaped cage with projecting rotating devices and multiple individual housing cells for at least one tank of fluid to be transported.

TECHNICAL FIELD OF THE INVENTION

The present invention refers to a “Maritime transport system of petroleum and its derivatives”, and is related to the sea, rivers, and other similar branch of petroleum and its by-products such as asphalt, fuel-oil, naphtha, etc.


STATE OF THE ART AND INNOVATIVE SOLUTION

In general and as it is known, the merchant transport ships are known and within them there are general cargo vessels, bulk carriers, oil tankers, methane tankers, chemical carriers, container ships, refrigerated ships, barge boats carrying vehicles and others (an illustrative example is cited in U.S. Pat. Nos. 3,882,809 A, 4,095,546 A, 6,321,673 B2).


Particularly, the oil tankers carrying cargoes that are divided into heavy or dirty (crude, asphalt, fuel oil) and light or clean, such as gasoline and other combustible liquid products and distillate cracking. These ships carry the previously mentioned cargo above cargo or fuel tanks that are found inside the ship and must have double hulls. For this, they need big engines with high fuel consumption because the hulls of these ships must turn off the water to move over it and the water skims all living ship work (which is under water) generates resistance to the advance to be overcome by applying power to the propellers through different types of engines.


The greater the length (long), greater the beam (wide) and the greater the draft (depth that is submerged) of the ship, this friction is greater. A greater the transport capacity of a ship, the greater is also the increase of these dimensions and therefore the friction area of the boat with the water increases and therefore also the power and fuel consumption, necessary to move at cruising speeds used in current world trade. This increase in fuel generates higher costs and also generates greater production of greenhouse gases.


The ecological problem caused by accidents in the water transport of this type of cargo, both sea and river, must also be considered. The oil spill causes environmental damage that is difficult to repair, with the consequent increase in insurance premiums and possible legal trials and their associated costs, in addition to the loss of cargo. Different circumstances that arise during the journey from a point of origin to a point of arrival can produce these spills, such as storms, catastrophic events, collisions, stranding, etc.


All these difficulties and disadvantages and consequently low yields, of its vessels, are overcome by the new transport system of the invention, which is simple in the construction and also has an easy assembly due to the reduced numbers of parts and shapes from the same.


The problem posed has led to think that the solution has to do with avoiding friction between water and the object that transports the oil or its derivatives. The transport system of the invention solves this problem, where the following advantages are obtained:


a) The friction is eliminated along a predetermined area and fixed (the hull of the ship) that is replaced by the friction of the water on an autonomous body, spherical, flat base that rotates while the tractor boat is moving forward, drastically reducing the friction that must be overcome to linearly move the load carrying spherical containers.


b) Greater transport capacity is obtained with equal power.


c) Lower fuel consumption is obtained with equal distance and tons of petroleum or petroleum derivatives.


d) Better chance to cross the Panama Canal with the same amount of tons transported by the largest oil tankers with lengths of 300 meters or more, they are unable to do so, restricting their routes or lengthening them excessively.


e) Greater range of options in the handling of containers upon arrival ports. Since the use of discharge conveyors spherical containers of all containers transport and in turn connect on the tractor boat new spherical conveyors and continue to other destinations without losing much time in the operation.


f) Possibility of extracting tanks carrying oil or its derivatives from spheroidal transport containers in port for clean ones out of the water.


g) Ability to change dirty tanks on conveyors spheroidal containers in the port for other clean ones.


h) Reduction of the waiting time in the port, which leads to a reduction in freight costs.


i) Less possibility of spillage and the possibility of recovering the cargo transported in case of storms or catastrophes.

With reference to FIG. 1, the container transport system comprises a tractor unit (T) with traction device (2) of at least one autonomous main container (1), of spheroidal volume, where said spheroid body rotates, which is in contact with the water and when moving in a straight line, pulled by said tractor unit, the force of friction of the water on the sphere generates its rotation.


With respect to FIG. 2, shows that the main container (1) has two hemispherical caps, one upper and one lower (3, 4), with a closed bottom and another open end, in whose bottom each contains a flat surface (5, 6); both caps are faced by their open ends and are joined in their circular perimeter by securing device (29) and sealing gasket (8) being both integral with each other, forming a spheroidal volume.


In FIG. 3, a lower structure of the self-supporting tank (14), individual tank (18) of the material to be transported, where it contains an upper and lower structure (25, 14) with connecting beams (26) in their assembly, defining a cube with rotating device (15) and self-supporting with multiple individual cells of housings of at least one tank (18) of fluid to be transported.


The self-supporting structure includes a damper mechanism (27) associated with said rotating device (15).


Traction on the spherical container (1) is exerted on the fixed part of a set of bearings (9, 10 and 13) via two cord-type connection devices (11) in each of them a drag chain by a hole through which the chain passes. The moving part of the bearing (9) which is integrally joined to the spherical container (1) by fastening nuts, allows its rotation.


The self-supporting structure (14, 25) is loaded into the cap (4) that is in contact with the water, on the flat surface (5) and then binds the other cap (3), both being adjusted by means of a belts locking (20, 21) with securing device (29) and sealing gasket (7, 8) and the two caps now forming a single spherical container (1). (See FIG. 5). In addition said at least one fluid tank has a gripping or clamping device (19) for its handling.


Also said at least one fluid tank has a filling/emptying conduit (23) of said fluid, a heating conduit (24), and an inert gas conduit (22). (See FIGS. 6 and 7).


Also said at least one floating and rotating spherical container (1), is associated with each other, with other containers of similar characteristic, by traction linkage and forming a consecutive row thereof.


Basically the external spherical container structure rolls by action of the passage of the water under its submerged part, while the cage of individual tanks in its place of shelter, remain fixed and stable. By moving the outer spheroidal structure simulates the behavior of a tire on the surface by which it rolls, in this case the water, instead of being a rigid tire that has to be forced to move along the same surface crawling. This circular movement reduces friction.
