Description

The invention relates to the field of environmental protection and can be used to localize spilled on the water surface of oil or oil products from the carrier ship in order to prevent their spread at the time of the accident.

The tasks that are set in the event of an accident with a carrier ship are to instantly localize the emergency spill in order to limit the spread of oil or oil products over a large area, to reduce the time for the spill to be eliminated by using modern technologies, equipment and material resources, as well as to minimize damage applied to the environment.

Known means for the localization of oil or oil products spilled on the water surface in the form of booms (see, for example, the website "www.northsea.ru" of the company "North Sea", producing these equipment). At the same time, booms can be of various designs and purposes: booms of constant buoyancy, emergency inflatable booms, sorbing booms.

A device is also known for the localization of floating contaminants (see, for example, RF patent No. 1759235), including a boom mounted at one end on a boat. The specified boom boom is equipped with a detachable connecting element consisting of two parts, one of which is fixed on the bow of the boat, the other on the free end of the boom, with the possibility of mechanical pairing of one part with another. The boom is hollow and connected to a source of compressed air.

A device is also known (see, for example, RF patent No. 2299078), which contains a hollow flexible boom boom, the ends of which are connected to two tugs, and an oil recovery vessel with oil pumping devices, made in the form of a catamaran, the hulls of which are attached to the frame located between them . Inside the frame, on the vertical axes having drives, there is a row of drums along the length of the frame and at least two rows of drums along its height. A separate boom tape is wound on each drum, having connecting elements at the ends for mechanical interfacing with adjacent tapes. The boom is made with the possibility of connecting its cavities with a source of compressed air and the release of air from them. The boom has the ability to disconnect from the tugs and lock it into a ring. The invention provides sufficient efficiency of localization and collection of oil or oil products due to the coverage of a large area of their spill and the speed of deployment of the boom, as well as due to the possibility of the simultaneous deployment of one part of the boom and its closure in the ring and coagulation of its other part. However, this device is used in combination with a special tugboat and a catamaran and is a special means of eliminating an environmental accident that has occurred, which comes to the aid of a ship that crashes after some time.

Also known is a means for quickly filling the boom sleeve by means of cans with CO ₂ gas or other gas located on the boom skirt (see, for example, US Patent No. US 5197821). However, this filling takes time, and this process cannot happen instantly in this case.

With regard to the placement of a boom fence on a carrier ship, it is known that the boom fence can be stored on board the ship in one place when assembled (see, for example, US patent No. US 5197821). It is also known that, in accordance with the requirements for the shipboard oil spill response kit (see, for example, Appendix No. 2 to the technical regulation “On the Safety of Inland Water Transport and Related Infrastructure”, page 2), the boom fence must be fixed on the ship and with easily detachable mounts. However, all this applies to special purpose ships designed to deal with the consequences of accidents.

The problem that is solved by the claimed invention in the event of an emergency on a carrier ship is to ring the potential leak of oil or oil products or stain oil spills to prevent their spread, to create a protective barrier around the vessel that serves as a potential source of oil spill or petroleum products, and in the localization of oil spills at the time of the accident.

The technical result, the achievement of which the claimed device is directed, consists in the quick release of the boom, its instant gas filling and placement on the water surface around the vessel.

In addition, the technical result, the achievement of which the claimed device is designed to place a boom on a carrier ship, is to ensure quick and easy use of a boom located on a carrier ship when receiving information about the accident.

To achieve the specified technical result in a boom barrier for localization of oil or oil products spilled from the carrier vessel on the water surface, made in the form of one closed gas-tight sleeve equipped with a valve for releasing gas, with a skirt weighed with weighting agents, or in the form of several closed in a single ring and equipped with valves for the release of gas of gas-tight hoses, each of which has a skirt, weighted with weighting agents, on the outside of each sleeve uniformly along its length and with hand, the opposing arrangement of the skirt with the weighting, the gas filling has Pyrocartridges exiting their gas filling devices inside the respective sleeves. In this case, the squibs that are mounted in each sleeve can be equipped with remote control devices for operation.

Distinctive features of the proposed boom fence is the location on the outside of each sleeve evenly along its length and from the side opposite to the location of the skirt with weighting agents, gas filling pyro-cartridges exiting with their gas filling devices inside the corresponding sleeve, as well as supplying the pyro-cartridges with remote control devices for operation.

To achieve the technical result, the inventive device for placing a boom rail on a carrier ship has brackets installed externally around the perimeter of the carrier ship, and each of them has upper and lower brackets pivotally connected to each other, connected by an automatically unlocked lock. In the specified device, the brackets can be installed on the carrier vessel externally along the bulwark.

Its distinctive features are the implementation of brackets outside the perimeter of the carrier ship, while each of them has pivotally connected upper and lower brackets connected by an automatically unlocked lock, as well as the installation of brackets on the carrier ship outside along the bulwark.

Due to the presence of the above signs, instant ringing of the place of potential leakage of oil or oil products or spots of already spilled oil products is provided in order to prevent their spread. In addition, a protective barrier is created around the vessel and a spot of oil or oil products spill is localized.

As for the arrangement of gas-filled pyro-cartridges in the boom that exit with their gas-filling devices inside the sleeve, pyro-cartridges used in automobiles for filling airbags with gas can be used as such (see, for example, the Avtotsentr automobile magazine on the Internet, section “ Equipment and service ”,“ No. 29 dated 07/09/2002, article “Inflatable safety”).

Figure 1 schematically shows a carrier ship of oil or petroleum products with a boom; figure 2 schematically shows a top view of a carrier ship with a boom spread out on a water surface around it; figure 3 schematically shows the fastening of the brackets and the lock on the bulwark; figure 4 schematically shows a cross section of a boom fence.

The inventive boom barrier for localization on the water surface of oil or oil products spilled from the carrier vessel 1, made in the form of one closed gas-tight sleeve 3 provided with a valve 2 for gas outlet, or several gas-tight sleeve 3 equipped with valves 2, closed in a single ring, contains the outside of each sleeve 3 uniformly spaced gas-filled squibs 4 extending with their gas-filling devices 5 into the sleeve 3. Each sleeve 3 has a skirt 6, an obstacle which is permeable to the penetration of oil or oil products and burdened with weighting agents 7. In this case, the squib 4 in each sleeve are evenly distributed along its length and from the side opposite to the location of the skirt 6 with weighting agents 7. If necessary, for the operation of the squib 4 are provided with remote control devices 8. In the absence of an accident the sleeve 3 is in the assembled state between the upper 9 and lower 10 brackets pivotally connected to each other, connected by locks 11, on the brackets 12 mounted on the upper deck 13, and which can be attached, for example, from the outside to the bulwark 14 using cables 15. The locks 11 can be automatic and operate according to a common signal.

When the carrier ship 1 moves oil or oil products quietly, the hoses 3 of the boom are placed on the brackets 12 and secured with the upper 9 and lower 10 brackets, which are connected by locks 11. In the event of an accident, the person in charge or the automatics leads to the simultaneous opening of all locks 11 and the operation of all the squibs 4, which, using their device 5, by burning, fill the gas-tight sleeve 3 with gas. Under the influence of its own gravity and due to the fact that it is located outside the transport vessel Chika, sleeve 3 slides off and turns out to be weighting materials 7 on the water surface, closing oil and oil products with the help of boom 3 and skirt 6, localizing the oil slick. With the help of cables 15, if necessary, can be adjusted its position from the boats. Thus, spilled oil or oil products will instantly be closed barrage boom. Further, liquidation of the leak of oil or oil products and repair work are carried out. Then, using the cables 15, the boom sleeves 3 are removed from the water, gas is released through the valve 2. Then it is cleaned, new squibs 4 are installed and placed on brackets 12, locking brackets 9 and 10 with locks 11.

The characteristics of the boom should be selected so that, in the inflated state, the sleeve 3 lies on the water surface in a “semi-flooded” state. For ease of maintenance, the sleeve 3 should be able to open the "ring" of the sleeve 3.
