Abstract

The invention relates to a boom system which can serve as a barrier (100) and an intermediate storage device at the same time. Said system comprises several basic elements which can be joined together in a similar manner to the components of "Lego". According to the invention, these pieces are not only longitudinally but also transversally interconnected to produce linear- or star-shaped or recticular barriers. A basic element consists of lightweight double film tubes (104', 104") which are pre-packed in bundles. The length of the film double tubes can be adjusted to suit the particular situation and can be e.g., between 5 and 400 metres. This novel system can be combined with the heavy booms of prior art for very serious accidents. It is however particularly suitable for small and medium-sized booms. Oil can be collected and accommodated most advantageously using skimmers.

Description

Device and kit for quickly laying out dirt barriers in the water

Technical field

The invention relates to a device and a kit for quickly laying out barriers in water, which are available as light, flexible double film tubes in packaged form and can be filled with a gaseous medium for use in an overhead chamber and as a bast in a lower chamber with a liquid medium are.

State of the art

The invention is based on W096 / 1 3638. This is explained as an integral part of the present application. It proposes to immediately contain oil accidents on the water by means of pollution protection barriers. Due to their lightness, the flexible pipes, which are stored folded together in containers, can be laid out very quickly, thereby preventing further spreading of the oil pollution. It is also intended to use the designed pipes as storage for the contaminated liquid. In contrast to the other known prior art, the W096 / 13638 allows the pollution control barrier to be filled with air and water at the same time as the double chamber pipe is being designed. This is done by successively ejecting the tube folded into the container at the rear of the container with the filling media and simultaneously pulling the container in the opposite direction. The concept can also be described as relocating an oil protection barrier from the can. Tests with prototypes that have now been manufactured have fully confirmed the function of the corresponding laying of a flexible pipe.

Presentation of the invention

The inventors had now set themselves the task of looking for cheaper solutions, which can be used effectively and very quickly in any strategy, even in medium and large-scale accidents, in particular with the sub-goal of optimal conditions for ecological removal of the pollution to create and stop the continued spread of floating pollution with a strategy adapted to each.

The device according to the invention is characterized in that the film double tubes have coupling rings at the end for the establishment of a longer lock and are designed as modules, the coupling ring leaving at least on one end side a large cross-sectional filling opening which is approximately the same cross-section as the chamber for the liquid medium.

The invention further relates to a kit for quickly laying out barriers in the water, according to the double-chamber tube principle, which are provided in a packet-like manner and can be filled with air in the upper chamber and with a liquid medium in the lower chamber, and is characterized in that it Has film double hose modules and Boyen, the flexible film double hoses have quick coupling parts on their ends, also suitable for longitudinal coupling boys and cross coupling boys, or with adapters to other systems, for setting up locks in a selectable constellation and / or for trapping liquid, buoyant substances.

The new invention is based on the core approach that primarily human power should be used for the construction of the so-called oil barriers with the greatest possible flexibility and speed, which is why a "composition game" is assumed. The individual module should be lightweight, especially in the case of inland waterways or ports, so that with human power, preferably a maximum of several men, can perform the entire handling. A module for the area of inland water should preferably weigh less than 60 kg, but at most 100 to 200 kg, so that the containers can be transported and placed at least into the water without crane aids. In contrast, the solutions known up to now in practice have weights of many tons, which can only be moved outside the water in a targeted manner using motor aids. These are designed for a longer duration of a lock. The new invention, however, wants a unit or element design for - 3 -

the fastest possible use, whereby the individual modules can be connected by quick couplings. The interaction of a large number of relatively short units, e.g. 20 to 80, in exceptional cases from 100 to 400 meters in length, has the great advantage that, depending on the particular accident situation, a specific solution and a specific procedural strategy can be selected and implemented immediately. Since the new solution is "quick and easy" as a basic concept, it is also suitable for larger accidents in combination with the previous heavy versions, which can be designed as a second safeguard with the necessary adapters if necessary. The efficiency of the new solution is particularly supported by a large number of advantageous configurations, as will be explained below. It is an experience fact that an accident as such cannot be calculated in advance. However, as is the case with oil accidents, an accident event can depend on the type of spread, e.g. the amount of oil spilled is estimated in terms of its spatial extent and an optimal response is planned. In this regard, the invention allows a completely new approach in that, depending on the local conditions, from the slight to the most serious accident, dispositives can be worked out in advance and what is decisive, the appropriate material, at least part of it, can be kept on site. Depending on the location, the minimum amount of barrier material can be kept ready for an oil weir in a port, in a canal, a river mouth, on a lake or sea shore. Another key point is that one or more barriers can be set up. A lock concept can also be selected, which is also ideal for capturing contaminated water. When mentioning oil in the application, it should primarily be understood to mean oil and derivatives of oil. However, this should not rule out the fact that other contaminants floating on the water surface can also be treated in the same way, i.e. in particular all liquids or floating materials that can inadvertently get into the water from storage facilities, tanks and pipes, but also solid floating substances, provided that do not force them to flow in as with raging rivers or in the bank area. The invention further relates to a whole number of particularly advantageous embodiments, for which reference is made to claims 2 to 14.

A pipeline itself is designed for straight or curved lines. If the area of the coupling is now additionally designed as an intersection or switch and double-chamber pipes branching off to the side, star-shaped or field-like, flat barriers can also be designed. The two older ones - 4 -

Publications GB-PS 1 554 737 and FR-PS 2 450 907 show two "picture buci or rice board solutions" of the prior art. If you have large oil tankers with ship lengths of e.g. 300 m, this results in barrier lengths of around one kilometer. The fact is that oil spills from large tankers on the open sea can quickly be several kilometers long and can be coherent, and at least initially do not consist of only relatively small oil areas on the water. If you also assume that a pipe length of 1000 m (e.g. according to FR-PS 2 450 907) is ready on the damaged ship, it will take hours before a second large voyage arrives on site. If the oil spill is then longer than the available barrier length, the barrier effect is questionable. A design concept in accordance with FR-PS 1 554 737 is even more problematic, since a capture loop has to be made from the start. The new solution, however, is not tied to any particular design pattern. By means of crossings and switches, a band-wise, a star-like or checkerboard-like layout, but also any practical shape, can be produced by the barriers. At least part of the double film tubes can also be used for collecting and temporarily storing contaminated medium. The design of the barrier can also be largely determined by the local flow direction of the water. A particularly ecologically sensitive coastal strip or a port facility can be protected or an oil spill can be encircled. As is well known, oil barriers cannot be used in extreme storm situations. In somewhat calmer conditions, the new solution immediately allows the double strategy of circling in, as well as capturing and buffering in at least some of the double film tubes, which can be brought to the scene of the accident as modules without any problems, even with helicopters. When installing the dirt barrier at the beginning of the design and / or the end of a double chamber train with long barriers, a swimming boy is advantageously arranged in between, in each case several modules, the swimming boy preferably being designed as a crossing or switch, with corresponding quick-action couplings for connecting additional double film tubes. High-tensile fastening points can be arranged over the entire length of the double film tubes in such a way that one or more double film tubes are slowly pulled transversely to their longitudinal axis and the contaminated medium is either moved in a desired direction and / or concentrated for quick and safe capture.

The double film tubes can be designed to be closable on both sides for both media. The film double tubes are made of thin, highly flexible and very resistant and particularly tear-resistant film material. The film tubes can also be constructed in multiple layers, at least one layer being able to have a reinforcement network, as is known in the case of building covers, and above all can prevent tearing. In addition, the film double hose is connected to the air supply outlet opening close to the flanges. The supply nozzle can also have a closable valve for the air, a safety valve or a non-return valve, and the passage for the liquid medium can also have a closure body or a non-return valve. A slight internal pressure, especially the gaseous medium, gives the flexible film tubes considerable stiffness after the finished design and is anchored as required. Fastening points can be attached to the double-chamber tube on the long side of the tube as towing eyes for traction means, for the transverse movements of a designed lock. According to a further embodiment, the device is assigned a cable guide or guide rails for the positioning of a module that is already in the water and a subsequent one for its exact positioning and quick coupling. The traction required for the design can be done by a small motor boat, but also by some watercraft or even by a helicopter. In order to obtain an even greater design option for the design of the lock, the swimming boys designed as crossing or switch points have at least three, preferably four or six coupling connection points. The swimming boys can have adjustable transfer tube pieces inside in the sense of a pipe switch.

As already mentioned, another key idea of the new solution is that the various components can be put together as a whole, like Lego blocks. Just like with fires, the first few minutes count the most, because then the extent of the damage is still relatively small and each measure is much more effective. It is advantageous if the connecting means are always the same. Another design idea is that the coupling parts can have coupling aids, e.g. in the form of a centering cone, or several correspondingly conical collision surfaces or insertion aids. As stated in the W096 / 1 3638 mentioned at the beginning, the two media can be introduced into the double-chamber pipes by means of coercive means such as pumps and blowers. In many cases, however, it will be more advantageous to allow the liquid medium, mostly water or already contaminated water, to flow into the oil chamber tube due to the drag effect. The water can be introduced without further technical aids, so that the staff - 6 -

only the air is blown in using aids. The individual constructive configurations can be used not only on the object shown in each case, but with corresponding adjustments also on all others. The new solution can e.g. can also be realized with the teaching of W096 / 1 3638, according to which the highly flexible film tube is stored by hand in the form of a hand organ. The flexible hose only receives the rigidity required by a lock after it has been designed and filled. The new solution combines the high flexibility of the film with dimensionally stable couplings at the respective hose ends. What is actually unusual is not just the opposites mentioned, but also the enormous dimensions, which in practice are usually over 40 cm up to 1.2 meters in diameter. The hose gets optimal flexibility when filled, so that it can follow small, local water movements surprisingly well despite the locking function. Due to their small dimensions (in the axial direction of the double film tubes), the couplings, which are dimensionally stable in relation to the water, do not hinder these local movements. The coupling of the double film tubes can be e.g. done on the ship. The experiments have shown that the coupling area of two double film tubes is very critical in that it must not be heavier than the rest of the tube, since otherwise this part tends to lower. The coupling parts should therefore be made of light material, such as aluminum or plastic.

Ways and implementation of the invention

Figure 1 shows a disposition when quickly laying a dirt barrier in the water. In the example, the entire lock 100 consists of three main parts, an anchoring point 101, consisting of a Boye 102, which is anchored via an anchor cable 103. From the buoy 102 to the right, an already designed double film tube 104 is tightly connected to the buoy 1 02. Foil double tubes 104 'or 104 "are shown from the buoy 102 to the left, which are fully designed. The foil double tube is shown schematically as a section i-i with FIG. 1 c and essentially consists of an outer, larger foil tube 105, and an enem inner, smaller film air hose 106. The film air hose 106 is filled with the gaseous medium, usually air with a slight overpressure, so that the film air hose 106 gives the barrier 100 an optimal buoyancy, and thereby ensure the locking function above the water surface with the desired dimension The remaining space between the film hose 105 and the film air hose 106 is filled with the liquid medium, ie primarily with water, for the design of the film double hose, reference is made to the known designs with a gasf shaped medium above the water has a barrier function and at least one chamber with a liquid medium in the water has a barrier function. FIG. 1 d shows a simplified section of the connection of the film double hose 104 'to the buoy 102. A coupling flange 107 acts as a coupling, which is firmly anchored to the buoy via a tensioning mechanism 109 and is connected to the film double hose 104' via a coupling ring 108 . FIG. 1 b shows the coupling of two abutting double film tubes 104 "and 104 '" by means of a coupling flange 107 and two coupling rings 108. As can be seen from FIGS. 1 b and 1 c, the water filling space 105' is between two adjacent double film tubes 104 "and 104"'in full cross section open. As a result, the coupling section does not act as a disturbance for the movement play of the hose in the light currents or wave movements in the water for the very light film double hose. So that the buoyancy in the area of the coupling flange 107 is optimally in equilibrium with the rest of the hose, the film air hose 106 can, as indicated in this area with 106 ', displace the water in the upper part. The slight overpressure in all foil air hoses

106 optimally and to be set approximately the same everywhere, the foil air tubes 106 can remain in permanent connection via a connecting tube 1 09 and two valves 1 10 in the designed state. A second valve 110 'serves to fill the film air hose as shown in FIG. 1. Filling takes place via a hose 1 1 1 from a boat 1 1 2 using a compressed air source, e.g. a fan 1 1 3 located on the boat. According to FIG. 1, the filler block 100 is filled for the water side by pulling the free opening end of the film double hose 105 by means of a pulling device 114 with the towing force of the boat 11 2, which is preferably designed as a motor boat. Depending on the selected design mode, it is also possible to fill with the gaseous medium with a second boat at the other end, as indicated by the dash-dotted line 1 1 1 '.

FIGS. 2a to 2c show on a larger scale a coupling flange 107 with an egg-shaped outline, the smaller dimensions being at the top in the area of the foil air hose 106. According to FIG. 2a, the coupling flange 107 has four eyelets 1 20 for connecting a pulling device 1 14. With two eyelets 1 20 in the lower part of the coupling flange 107, the tensile forces are transmitted more optimally into the film tube, so that the risk of tearing in the event of extreme fluctuations in the Tensile forces is reduced. In the upper part of the coupling flange

107, an indentation 1 21 is provided on both sides. The indentations 1 21 also relate in particular to the. circumferential grooves 1 22, in which the coupling ring 108 can be inserted. The coupling flange should be made of the lightest possible material and should have a small mass. It should only be so strong that it ensures the functions of coupling and distributing the power transmission to the film tube, but avoids local force peaks on the film.

Figures 3a and 3b show the coupling flange 107 in a three-dimensional representation in two different views. The indentations 1 21 on the one hand and the circumferential grooves 1 22 on the other hand can be clearly seen. FIG. 3c shows a section and FIG. 3d shows a section in FIG. 3a. The - 9 -

The number of grooves can be two or more for extreme load situations, the number of coupling rings must be increased accordingly.

FIGS. 4a and 4b show, on an enlarged scale, the area of the clamping lock 1 30, at the indentations 1 21. For each side to be tensioned there is an independently operable tension lock 1 30. The tension lock 1 30 consists of a locking head 1 31, in which a slot-shaped opening 1 32 is made in the area of the grooves 1 22 below. The endless coupling ring 108, around which the end of the film tube is wound, is inserted into the circumferential groove 1 22 in an untensioned state and fits into the slot-shaped opening 1 32, as can be seen in FIG. 4b. As a result, the coupling ring 1 08 is clamped downward into the indentation 1 21 with a symbolically illustrated screw 1 33. As a result, the entire coupling ring 108 together with the film wrapped around the coupling ring 108 is tensioned and clamped securely in the groove 1 22.

FIG. 5 shows a 3-part pulling device on a larger scale. As already mentioned, a 4-part or multi-part pulling device is preferred for higher loads. Experiments have shown that the traction device should be arranged in such a way that the flange 107 is pulled in a slightly inclined position. An optimal incline is around 20 to 30 °, with the lowest tip at the front.

FIGS. 6a to 6d show various termination devices 140, which can preferably be attached and detached again using the clamping system described above. FIG. 6a shows the further possibility with an end closure with an additional cover 141. A water filler neck 142 is additionally arranged in FIG. 6c. This is used to fill the liquid medium using a pump with a corresponding hose connection. In FIG. 6d, the closure consists of film material with a connection via a coupling ring. According to FIG. 6b, the closure consists of a plate 143 which is screwed onto the coupling flange 107.

FIG. 7a shows a simplified coupling flange 107 'which only covers the lower part and, above all, also serves to attach the traction means. Figures 7b and 7c show a barrier for bank protection. The flexible barrier according to FIG. 7b serves to close off the shallow water. The procedure here is as follows: The end cover is installed at the end, depending on the shallow water area, residual water is only introduced after positioning and the cover is installed and the lock is fixed. The flexible - 10 -

The barrier according to FIG. 7c replaces the otherwise customary bank barriers and is mounted on the last part of the floating barrier. The steps are as follows:

- Mount the end cover

- pulling up the lock (cable apparatus)

- Place a blanket under the barrier protection

- fix the lock at prepared locations, tree, titanium anchoring)

Figure 7d shows the use of a buoy with rope anchoring in a 3-sided buoy.

FIG. 8a shows the possibility of rolling up or rolling off a suitably packaged double film tube. FIGS. 8b to 8e show various examples for packaging the double film tubes. At the same time, this also results in the possibility of storage, storage, and transport. From the optimal design mode to be expected, the example shown can be used to decide whether the type and quantity of modules is ready. FIG. 8b shows the container solution with the following features:

- Fixed container shell on a flange

- Double-shell container with quick-release fasteners

- Transport handles or pallet storage

- Impact resistant material

FIG. 8c shows the carrier bag solution, which can have the following features:

- Bag made of plasticized fabric

- handles

- Weight of the lock for 2 or 4 people.

FIG. 8d shows the use of locks, preferably with longer individual modules in transport pallets. In extreme cases, a double film tube can have a length of 100 to 400 meters and can be kept ready as a single piece or as many individual modules. FIG. 8e shows the possibility of having the double film tubes ready on reels. Of course, the different variants can be kept available in any combination, depending on the special dispositions that are suitable for use or in the manner in which they are required for an expected accident situation.

Figure 10 shows another coupling option. Because the open cross-sectional shape is out of round, in the simplest case, a second flange can be connected in a tensile manner by a twisting movement when fitting. Because both bodies have one - 11 -

have an oval shape, one can be inserted by turning it slightly and then pressed tightly by turning it back.

Figures 9a, 9b and 9c show three further possible combinations of the modules. FIG. 9a shows the core functional parts of a hose module:

• two dimensionally stable coupling flanges 2 and 3 as well

• A flexible film tube 4 folded into itself. The whole

The module is covered with a protective film, for example a shrink film 5 or a sack, which is intended as storage and transport protection against mechanical damage and against weather influences and must be removed before use. As a further transport and storage safeguard, a strong band 6 can be stretched directly around the module so that the film folded in with some pressing force remains together. FIG. 9b is based on the same basic components, but additionally has a guide tube 7 with a small cross-section for the gaseous medium and a guide tube 8 with a large cross-section for the liquid medium. The module 1 ^x according to FIG. 9b can be surrounded with a stronger protective jacket 9. The protective jacket 9 can, for example, also be a thick-walled shrink film which is held on one side with a drawstring 10. Before the lock is laid out, only the tension band 10 needs to be released, the gaseous medium introduced via the air connection 11 and the liquid medium introduced via the water inlet opening 12. Figure 9c shows a robust module 1 ^xx with a housing 1 3 and a cover 14 respectively. 1 5 on the two end sides of the module, whereby the cover 1 5 is shown lifted off for module 1 ^xx . The three variants shown result in very interesting applications, also depending on the particular application. The solution according to FIG. 9a allows a large number of modules to be kept available with the lowest possible basic costs and to be designed in large lengths in the shortest possible time. The solution according to FIG. 9a allows the self-folded film tube as a double tube to be pulled out like a hand organ, depending on the intended length, for example 30, 50 or 100 meters in length on the water, with the air filling being able to be started at the same time. The lock can then be extended by any other modules. The lock design can be carried out without interrupting the air filling if in each of the two coupling flanges 2 and 3 a valve 1 6 or. 1 7 is arranged and this is forcibly opened when flange-mounting the following one, for example by a nose 1 8. With this variant, coupling can be carried out with little force, since the film material, when not filled, follows the movement of the coupling flange like a piece of cloth - 12 -

and it can be inserted and clamped by hand in the next coupling flange. The solution according to FIG. 9c has only one guide tube for the gaseous medium and is suitable e.g. for filling by towing. The end of the ejection remains closed with the sealing cover 1 4. At the beginning of the design, only the sealing cap 1 5 is removed, so that the water can penetrate through the filling opening 1 2. The housing 1 3 protects the film tube 4 even during a long storage period and can offer advantages where some modules with the same film tubes several times e.g. be used for practice purposes. The solution according to FIG. 9a is the only one of the three examples which, instead of the preferred folding in itself according to WO 96/13638 cited at the beginning, allows a helical folding, for example according to FR-PS 1 1 21 333, as is known in the folding of textile fabrics .

Figure 1 1 shows the solution of Figure 9c on a larger scale. The container 1 3 has a double wall 20, 21. The double wall can save weight and ensure that the module can float even if it remains in the water for a long time. Both coupling flanges 2 and 3 are made in several parts. This simplifies, above all, the assembly or insertion and folding of the film tube 4. The film tube 4 is in each case provided by two inner sealing rings 22, 23 in a corresponding recess 24 in a flange ring 25 by means of screws 26 and. 27, 27 'tightly and firmly held with the respective coupling flange. The closure cover can be secured like a lock bolt by means of a plurality of bolts 28 and a matching rotating ring. The same system also serves to securely lock two coupling flanges when connecting modules. A recess 30 ensures that the closure cover 1 5 does not actuate the valve nose 1 8.

Figures 1 2a to 1 2c show a Boye, which on the one hand has an analogous function as a tube module with the film tubes. Both the gaseous medium and the liquid medium can be supplied via the Boye. The Boye in the version shown interrupts the air flow. It represents the end or beginning of the air flow in each direction, depending on the observation. The Boye has two other important functions. Through a bottom opening 60, water as the liquid medium can be introduced into the lower chamber via a submersible pump 61. The other important function is the possibility of crossing. With the modules described so far, any length can only be assembled in one axis direction, for example the XX axis. The Boye now also allows you to lay modules or blocks across the YY axis. For the - 13 -

The layout strategy opens up a completely new dimension. With regard to the coupling connections, the Boye is identical to the corresponding ends of the hose modules. The Boye is designed to float with an optimal immersion depth. It is important for the barrier function that in the Boye area the barrier protrudes approximately equally deep into the water and above the water level. Another purpose of the Boye is to anchor the position in question. The openings for the liquid medium that are not required are closed by a cover. With the Boyen, a certain number of hose modules can also be used for the separation. For example, With very large barrier lengths, a Boye can be placed after every 10 hose modules.

The device according to the new solution can be designed in accordance with W096 / 1 3638 in such a way that the following method is possible for the mode of operation: Method for quickly designing a bendable contamination protection barrier, which is folded up and kept ready as a tube and, in the designed state, double-room, longitudinal and superimposed chambers divided, an upper chamber with gas or air and a lower with a liquid medium as a Baiast can be filled. The tube can be designed on the one hand with a closed end as a bag bottom and on the other hand with an open, closable end for the liquid medium and with a closure for filling gas or air, with adjacent or interleaved chambers preferably in themselves, i.e. folded on its own bendable walls, held ready in a container and the open side of the tube can be at one end of the container. The bendable tube can be filled on the basis of the inlet of gaseous and liquid medium, the flexible tube being stored as a package folded inside the container in the initial phase. However, the liquid chamber can also result from dragging the container in the water with the liquid medium, i.e. Water must be filled until the pipe is fully deployed as an anti-pollution barrier. After the flexible pipe has been completely unfolded and filled with the two media, the open side can be closed. Depending on the ratio, the liquid medium can also be introduced into the lower chamber either via liquid pumps or by filling as a result of dragging. In the second case, the double hose is designed like a bag bottom at the end, or the side in question is closed by a cover. The preferred embodiment according to the new solution has (apart from the valves) an airtight chamber for the gaseous medium and an open chamber which can be closed as required for the liquid medium.
