Abstract

Arrangement for the extraction of crude oil from sunken tankers, by seafloor packaging, which consists in fixing the upper part of the wreck and on the crude oil tanks of an inverted anchored hopper, receiving material that emerges from a drilling made from the hull up to the tanks, presenting in the upper part of the hopper (1), a conduit (4) in which a plurality of chained segments (10) that fill the bags or containers (10) are coupled, being configured the containers (10) as woven bags with synthetic fiber, reinforced raffia type.

Description

Crude Extraction Provision of sunken tankers, by seabed packaging.

Object of the invention

The present specification refers to an Invention Patent application, corresponding to a disposal of crude oil from sunken tankers, by seafloor packaging, whose obvious purpose lies in be configured as a provision able to anchor a hopper at the top of the wreck, specifically on the crude oil tanks positioned inverted, capable of receiving the material to be extracted that emerges from the tanks carrying the crude by a perforation made from the outer area of the hull to penetrate the tanks.

Crude oil is extracted continuously by using a cylindrical duct through which fill the bags or containers that after being sealed go rising gradually until it reaches the surface of the sea, from which they are extracted to deposit on ships responsible for transport to the area where they must be treated the contents of them.

Field of the Invention

This invention has its application within the industry dedicated to the recovery of polluting products incorporated inside sunken ships.

Background of the invention

The job is known by the applicant currently of different systems, procedures and provisions that are configured from pumping actions and encapsulation

Regarding the pumping it should be indicated that due to the low fluidity of the product to be pumped, which increases with the greatest pumping depth, operations are required to fluidize the crude to extract incorporated inside the tanks of the sunken ships, using polluting fatty products.

It has also been found that in operations of extraction of crude oil incorporated in sunken ships, together with the crude that is extracted is also done lifting a large amount of water that is sucked along with the crude, and at the same time with the products added, increasing the volume of matter extracted.

To carry out pumping operations, requires the use of a large amount of energy to perform the pumping in question, and subsequently cleaning the product extracted.

The fact of ceasing the performance of this type of operations when the pumping operations by bad sea, and at the same time by an increase progressive difficulty at greater depth.

The need for heat the oil in order to increase its fluidity and enable pumping

Regarding encapsulation, it should be noted that the difficulties of these operations overcome the difficulties of pumping operations, without extracting matter "supposedly protected" contaminant.

The obvious solution to this problem, is to have a procedure, system or arrangement, in which does not exist continuous direct connection with the wreck, which limits the time of connection of the chains to the hoppers, which is supposedly with good sea, and at the same time they would not be needed pumping operations, because the bags emerge by buoyancy to the sea surface.

There should also be a provision, in which the meteorology did not influence, since the invention He works with the ships anchored in the shelter.

Containers containers of extracted oil will be properly marked with radio beacons previously placed, which would lead to crude oil bags determine their position at sea and can be towed to shelter or its relevant transferred to the ship.

However, on the part of the applicant ignores the existence at present of an invention that present the characteristics described in this report.

Description of the invention

The crude oil extraction arrangement of sunken tankers, by seabed packaging that the invention proposes, is configured as a provision that does not consume energy, when working autonomously, except when connected the chains of bags, and the invention allows to continue working of indefinitely, collecting waste from the wreck, until it keep the bags that have been previously installed.

More specifically, the provision of crude oil extraction from sunken tankers, by packaging in the seabed is constituted from the anchorage of a hopper in the upper part of the wreck, over the oil tanks, being the hopper positioned inverted and receiving the material that emerges by a perforation made until contact with the area internal of the tanks carrying the crude oil to be extracted.

In the upper part of the hopper a cylindrical duct that fills the bags or containers, and these containers They are configured as woven bags with synthetic fiber, type reinforced raffia.

Once the bags have been completely full, detach from the filling duct and float up reach the surface.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, is attached herein descriptive, as an integral part of it, a set of planes in which with an illustrative and non-limiting nature, it has been represented the following:

Figure number 1.- Corresponds to a view synthesized of the object of the invention, corresponding to a disposal of crude oil from sunken tankers, by Bottom seabed.

Figure number 2.- They show the bags in the inside of which the extracted oil is mobilized in vertical direction ascending until reaching the surface of the sea.

Preferred Embodiment of the Invention

With the collaboration of the cited drawings and described above, it can be seen that the provision of crude oil extraction from sunken tankers, by packaging in the seabed, is constituted from the fixation on the sunken ship hull of an inverted anchored hopper (1), specifically in the upper part of the wreck, the inverted hopper (1) to receive the crude oil (2) emerging from the tanks, emerging the crude through a drilling performed on the hull of the ship until reaching the tanks.

In the upper part of the hopper (1) it is crimped a cylindrical duct (4) that fills the bags (10) with the crude oil (2) extracted and gradually emerging from the tanks, It should be noted that the containers (10) or bags are constituted as woven bags with synthetic fiber, reinforced raffia type, and once you fill the bags (10), they detach from the duct filled (4) and float to the surface.

Obviously sacks, containers or bags (10) they have to be determined according to the volume for their best use and management, presenting means of sealing Hydraulics of the hoppers (1) to the hull of the wreck.

The invention has a filling chain (5) from the mouth of the hopper, as well as the closure of the hopper (1) when the last bag (10) is detached.

The bag filling duct (10) is It consists of single-type cylindrical segments, interlocked between Yes, as they can be chained.

Each segment is sheathed with a piece of bag that receives the crude (2).

When the volume of matter (2) packed arrives at a certain degree of buoyancy, the devices of sealed, releasing the segment or bag (10), sealing it and detached begins to float gradually, beginning to fill the one below.

The last segment or bag connected to the hopper (1) and specifically to its mouth (4), when detached generates the hermetic closing of the mouth.

When a new chain (5) of segments or bags (10), the mouth (4) of the hopper (1) opens.

The segment chains (10) can be the long that allow sea currents and the technique of coupling

The descent of the chains is driven by a serve (3) or end connected to the wreck of the helmet, indicating that the set of concatenated segments has been referenced from general form with (5), although each unit segments or containers have been referenced with (10).

The coupling segment with the hopper leads to a hydraulic conduit that will operate from the surface the coupling mechanisms, and the hydraulic conduit is will use in the connection of all the chains (5) to their respective hoppers
