Description

The invention relates to a device for the safe dismantling of salvaged ordnance.

In the North Sea and Baltic Sea in particular there are large quantities of ordnance in the broadest sense. Some of these are objects that have been deployed in a targeted manner, such as mines, for example anchor rope mines. Furthermore, it is also about duds, which were used in combat operations. Furthermore, just after the end of the war, very large quantities of ordnance were simply dumped. Especially the latter also includes weapons with chemical warfare agents. These objects range in size from rifle or machine gun ammunition to mines, naval artillery shells and bombs. It is suspected that there are at least 5 million suspected objects in the North Sea and Baltic Sea that could be such ammunition.

All of this ammunition has now been lying in saline water for over 75 years. As a result, this ammunition has a completely undefined state of decay and in particular with regard to the tightness, the chemical stability of the explosives contained and the transport safety.

On the one hand, the ammunition poses a great danger. For example, war gases can escape over time due to corrosion, which poses a great danger. Ships can also come into contact with the ammunition and trigger it. In the case of anchor rope mines, there is a risk that the chain connecting the mine to the ground will be separated and the mine will become a floating mine and can thus also reach areas that are thought to be safe, for example a fairway. Leaked and washed up white phosphorus regularly causes injuries. Therefore, it would be desirable to remove all objects.

On the other hand, however, the evacuation is very critical, since the ordnance has to be touched, moved or even dismantled. With all these actions, there is of course an extremely increased risk that there will be a reaction in the explosives. It is therefore advantageous to minimize the number of movements.

If a suspicious object is found, a decision must be made after an inspection as to whether the object is transportable or can be made. For example, duds can be made transportable by removing the detonator if necessary.

Transportable objects must then be transported for delaboration. However, many objects are too large to be burned directly, for example, because the quantity of explosives that are burned at the same time would then be too high to still safely control the process.

From the WO 2007/068020 A1 a transportable system for defusing ammunition containing fluid warfare agents is known.

From the DE 10 2018 119 339 A1 a method and a device for defusing a dud lying under water is known.

From the DE 39 13 479 C1 a method and a system for dismantling toxic and/or explosive objects, in particular chemical weapons, is known.

It would therefore be desirable to minimize the transportation distance of an object found underwater and to dismantle the object safely and with minimal movement. The problem here, however, is that it is much more difficult to construct appropriate bunkers or earth walls at sea, since the weight would far exceed that which a floating platform could bear.

This is also desirable because ammunition that is located outside the sovereign areas, i.e. outside the territorial sea of the 12-mile zone, is sometimes difficult or impossible to bring ashore for legal reasons. A shipment of ammunition and especially chemical weapons from outside this area into the sovereign territory of a state can already be legally problematic or impossible, for example on the basis of the Chemical Weapons Convention and national laws.

It must therefore be taken into account at all times that there is a risk that the whole quantity of explosive will detonate at once. In particular, this risk naturally exists at times when mechanical work is being done on the object. In this context, it must be taken into account that, especially in the case of an application at sea, space and weight are not available to an unlimited extent and therefore the protection of the other equipment, the personnel, but also in particular the supporting platform must be ensured in such a contingency . Of course, it must also be taken into account that shrapnel generated by an explosion in particular poses a significant threat.

The object of the invention is to create a device that allows safe dismantling at sea.

This object is achieved by the delaboration chamber with the features specified in claim 1, the buoyant delaboration platform with the features specified in claim 8 and by the method with the features specified in claim 11. Advantageous developments result from the dependent claims, the following description and the drawings.

The delaboration chamber according to the invention has an outer housing. The outer housing can be closed with a removable cover. The delaboration chamber has an inner floor, with a first chamber area being formed below the inner floor by the inner floor and the outer housing. The first chamber area is preferably closed. The first chamber area is filled with a flowable or solid medium. For example and preferably, the first chamber area is filled with concrete, sand or water. The inner floor has a recess for receiving an explosive object. Here, the explosive object (ord) should be completely within the cavity. As a result, in the event of an unwanted detonation, part of the pressure wave would be directed against the inner floor and thus against the filling of the first chamber region. This geometry is intended to deflect the pressure wave from the detonation at least partially against the area with the lowest resistance, i.e. upwards. When closed, the cover is connected to the outer housing in a shockproof manner.

This keeps the lid in place even in the event of a detonation. The cover has a pressure relief, the pressure relief having at least one deflection for the detonation gases. The purpose of the pressure relief is to divert the gases and pressures produced by a detonation in a targeted manner. Despite the high pressure, these gases need to be diverted to prevent shrapnel from escaping the delaboration chamber and damaging other pieces of equipment or even injuring personnel.

A deflection within the meaning of the invention is any device which deflects a gas flow and thus prevents the gas flow from being guided in a straight line. The reason for this is that shrapnel, for example, moves in a straight line after a detonation and should not escape through the pressure relief. The pressure relief can be designed, for example, in a spiral shape or as a labyrinth with right-angled deflections.

A removable cover can be lifted, folded or pushed within the meaning of the invention, for example. It is essential that the cover can be removed in such a way that an ordnance can be lifted into the delaboration chamber from above. After closing, however, the cover must be firmly connected to the outer housing so that the cover does not become detached from the outer housing even in the event of an accidental detonation of the ordnance. Because that would turn the lid itself into a projectile. Due to the high mechanical requirements when closed, a sliding cover is preferred. For this purpose, the cover is brought horizontally into a position next to the delaboration chamber in order to open the delaboration chamber.

In addition to liquids, a flowable medium also includes flowable solids, in particular loose beds. For example, sand or gravel is a free-flowing medium within the meaning of the invention. In the event of a shock, deformation is possible due to a flowable medium, while at the same time power transmission is still possible.

The outer case and lid feature protection against 20mm Fragment Simulating Projectiles (FSP) per MIL-DTL-46593. The weight of the shrapnel is approx. 53.8g, with shrapnel with a kinetic energy of at least 67kJ being held back safely. This corresponds to protection class G9 according to NATO standard STANAG 2920.

In one embodiment of the invention, the inner base is a removable base container, as a result of which the first chamber region is formed by inserting the base container. For this purpose, the bottom container particularly preferably has a closable opening, preferably made at a high point, for example in a wall of the bottom container, in order to be able to fill a medium or a precursor forming the medium into the first chamber area. An example of a precursor forming the medium can be liquid concrete that has not yet hardened or a monomer or oligomer which is polymerized in the first chamber region. In the case of a hardening precursor, the hardened medium itself can also cause the opening to close.

In a further alternative embodiment, the inner floor and the first chamber area are formed by a chamber container. For example, the chamber container is a hollow body that can be filled with water or sand, for example, preferably after it has been inserted into the delaboration chamber. For this purpose, the chamber container preferably has a closable opening, which is preferably arranged at a high point of the chamber container.

In a further embodiment, the cover is designed as a hollow body which can be filled with a flowable medium. The cavity in the lid can itself be designed to be leak-tight for the flowable medium, or the medium is introduced into the cavity in a container, for example a leak-proof bag. A cover designed as a hollow body particularly preferably has additional stiffeners between the upper side and the underside, for example in the form of ring stiffeners or diagonal stiffeners. The pressure relief is in this embodiment connected between the top and bottom of the lid to allow gas passage. A fire-retardant medium is particularly preferably used here as the flowable medium, in the simplest case water.

In a further embodiment of the invention, the deleboration chamber has at least one cutting device. The cutting device is preferably a water jet device. In this embodiment, the delaboration chamber has a water drain, with the water drain running through the inner floor, the first chamber region and the outer housing. The pressure pump for generating the water under high pressure is preferably arranged outside the delaboration chamber. The pressure pump is preferably arranged below the top level of the inner floor. The pressure pump is thus protected particularly efficiently against pressure waves. A pressure pump can also supply water under high pressure to two or more cutters in two or more delaboration chambers. The cutting device is particularly preferably remotely controllable and can be operated from a remote control device.

In a further embodiment of the invention, the delaboration chamber has at least one first chamber lifting device. The chamber lifting device is used to lift out of the recess ammunition parts that have been severed from an ordnance.

In a further embodiment of the invention, the pressure relief is ensured by a predetermined breaking point in the cover. The predetermined breaking point fails at a defined gas pressure as a result of an unwanted detonation during delaboration and releases a nozzle-shaped outlet. Various metal sheets are arranged in the nozzle-shaped outlet, which, in their function as baffles, ensure that the resulting explosive gas is deflected and slowed down. As a result, the resulting explosion gases escape upwards in a targeted manner, so that the neighboring components of the delaboration platform are protected. The arrangement of the guide plates in the outlet also provides protection against the escape of shrapnel. In particular, the predetermined breaking point can be circular. Alternatively, it can be provided that the predetermined breaking point is movably fastened to the cover and prevented from moving via an overload safety device, the overload safety device being dimensioned in such a way that it fails when pressure is applied before the cover gives way overall. For example, it may be a hinged cover secured against rotation with a shear pin.

In a further embodiment of the invention, the inner base has a flat storage surface, the storage surface being arranged above the depression for receiving an explosive object (ordnance). This means that fragments of ammunition can be stored in an area that is not directly affected by a detonation and the chance is increased that they may not be moved during the detonation, thereby reducing the overall damage.

In a further embodiment of the invention, the delaboration chamber is connected to a gas cleaning system. If the munition is a weapon containing a chemical warfare agent, there is a high probability that it will be released when the munition fragments. It is therefore desirable to be able to remove the chemical warfare agent from the air in the delaboration chamber before it is opened and the chemical warfare agents would be released directly into the atmosphere. In the simplest case, the air is fed into a combustion chamber or directly into a torch via a simple suction system and rendered harmless by burning. Alternatively or additionally, filters, for example activated carbon filters, can be used.

In a further embodiment of the invention, the pressure relief is connected to a gas cleaning system. This has the advantage that even in the event of an unintentional detonation of a weapon containing a chemical warfare agent, there is no release and there is no risk to people.

In a further aspect, the invention relates to a buoyant delaboration platform. A buoyant platform within the meaning of the invention can be, for example, a ship, a pontoon, a barge, a raft, a semi-submersible platform or a jack-up platform.

The buoyant delaboration platform has at least one first lifting device, at least one first delabora according to the invention tion chamber and at least one first combustion device.

The great advantage of such a buoyant delaboration platform is, on the one hand, that the number of times a weapon has to be transported until it is finally destroyed is minimized, thus reducing the risk of an unwanted detonation. On the other hand, it is also possible, for example, to destroy chemical warfare agents that are found outside the 12-mile zone without having to import them into a country.

In a further embodiment of the invention, the buoyant dismantling platform has at least a first platform area and a second platform area. The at least one first delaboration chamber is arranged in the first platform area and the at least one first combustion device is arranged in the second platform area. At least one first protective element is arranged between the first platform area and the second platform area, wherein the at least one first protective element has a surface. The surface of the protective element has an angle of 120° to 150° to the surface of the first platform area and an angle of 30° to 60° to the surface of the second platform area. As a result, a pressure wave originating from a detonation in a delaboration chamber would be deflected upwards and the combustion device located behind would thus be protected.

In a further embodiment of the invention, the buoyant dismantling platform has a transport device for transporting ammunition parts from the at least one first dismantling chamber to the at least one first combustion device. The transport device can be, for example, a conveyor belt, transport rail or other continuous transport system on which the ammunition parts rest directly or transport containers in which the ammunition parts lie. The conveyor belt can be controlled automatically.

1. a) Heben eines Kampfmittels aus dem Wasser mittels der wenigstens einen ersten Hebevorrichtung.
2. b) Verschwenken des Kampfmittels über die wenigstens eine erste Delaborationskammer, wobei die Delaborationskammer auf der schwimmfähigen Delaborationskammer angeordnet ist und wobei der Deckel der wenigstens einen ersten Delaborationskammer geöffnet ist,
3. c) Absenken des Kampfmittels in die wenigstens eine erste Delaborationskammer in die Vertiefung des inneren Bodens,
4. d) Verschließen der wenigstens einen ersten Delaborationskammer mit dem Deckel,
5. e) Zerteilen des Kampfmittels innerhalb der Delaborationskammer, wobei ein Munitionsteilstück, bevorzugt in einer Größe von 5 kg bis 10 kg, abgetrennt wird,
6. f) Wiederholen des Schrittes e) bis das Kampfmittel soweit zerlegt ist, dass es weiter verarbeitet werden kann,
7. g) Öffnen der wenigstens einen ersten Delaborationskammer durch Entfernen des Deckels,
8. h) Herausheben der Munitionsteilstücke aus der wenigstens einen ersten Delaborationskammer,
9. i) Transport der Munitionsteilstücke zur wenigstens einen ersten Verbrennungsvorrichtung,
10. j) Verbrennung der Munitionsteilstücke in der wenigstens einen ersten Verbrennungsvorrichtung.

In a further aspect, the invention relates to a method for destroying submerged ordnance using a buoyant delaboration platform according to the invention. The procedure has the following steps:

1. a) lifting a weapon out of the water by means of the at least one first lifting device.
2. b) Pivoting the munitions over the at least one first delaboration chamber, wherein the delaboration chamber is arranged on the buoyant delaboration chamber and the cover of the at least one first delaboration chamber is open,
3. c) lowering of the ordnance into the at least one first delaboration chamber in the recess of the inner floor,
4. d) closing the at least one first delaboration chamber with the lid,
5. e) cutting up the explosive ordnance within the delaboration chamber, with a piece of ammunition, preferably with a size of 5 kg to 10 kg, being cut off,
6. f) repeating step e) until the ordnance has been dismantled to the extent that it can be further processed,
7. g) opening the at least one first delaboration chamber by removing the lid,
8. h) lifting the ammunition parts out of the at least one first delaboration chamber,
9. i) transport of the ammunition parts to at least one first combustion device,
10. j) Combustion of the ammunition parts in the at least one first combustion device.

The great advantage of the method according to the invention is that the transport of a weapon is minimized. It is lifted out of the water in one action and placed directly in the delaboration chamber. Further interim storage and transport can thus be avoided. Every relocation and every transport represents an additional risk that an unwanted detonation will occur.

Because the explosive ordnance is completely broken up into small, directly combustible pieces of ammunition, subsequent processing and final destruction is comparatively simple. The delaboration chamber is closed during all intermediate steps in the fragmentation of the ordnance, so that all extremely risky steps are carried out in such a way that the protection of the buoyant delaboration platform has high priority. The ordnance is then completely dismantled when it has been broken down into such small parts that further processing of all individual parts and thus of the entire ordnance is possible. For example, can be burned in an incinerator without damaging it.

In a further embodiment of the invention, in step e) after the fragmentation of the ordnance, the ammunition section is moved to a flat surface of the inner floor. For example, this area can also be a transport container located inside the delaboration chamber. The advantage is that the munitions fragments that have already been separated do not interfere with the further fragmentation of the ordnance and, if necessary, in the event of an unintentional explosion of the ordnance, do not detonate in the further fragmentation or only detonate with a delay, so that the strength of the pressure wave of the detonation can be reduced.

In a further embodiment of the invention, between step c) and step d), a fluoroscopy device is placed on the opened delaboration chamber. The ordnance is x-rayed with the x-ray device. The X-ray device is then removed again. This has the advantage that the ordnance does not first have to be placed in a screening device or even transported through it. After being dropped, the ordnance remains unmoved. This minimizes the risk of an unwanted detonation during fluoroscopy. For example and preferably, the X-rays are used for the X-rays. The X-rays can be generated, for example, by an X-ray tube. A free-electron laser can also be used as a source to provide the necessary energy for x-raying a heavy metal housing.

In an alternative embodiment, before step c), a screening device is placed on the opened delaboration chamber, through which a weapon can be transported into the delaboration chamber. After step c) and before step d), the X-ray device is removed. This embodiment also has the advantage that the ordnance does not have to be additionally introduced into a separate X-ray device and removed from it again. Rather, in this embodiment, it is x-rayed while it is being introduced into the delaboration chamber.

In a further embodiment of the invention, the explosive ordnance is lifted out of the water in a transport container in step a) and introduced into the delaboration chamber in the transport container in step c). Then, in step e), it is cut up in the transport container or with the transport container. This means that the ordnance does not have to be reburied again. The ordnance is placed under water in the transport container and provided that this step, which is also protected by the water column located above the ordnance, the ordnance is no longer moved relative to the transport container, thereby minimizing the risk of unwanted detonation. Depending on the ordnance, type or size of ordnance, but also depending on the type of cutting device, it can be advantageous to cut the transport container together with the ordnance. Of course, this has the disadvantage that the transport container can only be used once, but it may have the advantage of further minimizing the movement of the ordnance.

In a further embodiment of the invention, the ammunition parts are placed in cardboard boxes in step a), transported in the cardboard boxes in steps h) and i) and incinerated with the cardboard boxes in step j).

• 1 Delaborationskammer
• 2 Schwimmfähige Delaborationsplattform

The delaboration chamber according to the invention and the buoyant delaboration platform are explained in more detail below using an exemplary embodiment illustrated in the drawings.

• 1 delaboration chamber
• 2 Floating delaboration platform

In 1 a delaboration chamber 10 is shown. The delaboration chamber 10 has an outer housing 20 and can be closed with a removable cover 30 . For example, the cover 30 can be moved horizontally in order to open the delaboration chamber 10 . In the example shown, the outer housing 20 and cover 30 are designed according to protection class G9 according to the NATO standard STANAG 2920 in order to be able to effectively hold back shrapnel with up to 67 kJ. Likewise, the connection between the outer housing 20 and the cover 30 is designed in such a way that the cover 30 is not separated from the outer housing 20 in the event of a detonation.

Inside the delaboration chamber 10 there is an inner floor 40 which has a recess 110 for receiving a weapon 90 . A first chamber area 50 is formed between the outer housing 20 and the inner floor, which is filled with sand in the example shown. Alternatively, the first chamber area 50 could be filled with concrete.

The cover 30 has a pressure relief 60 which, in the example shown, is in the form of a labyrinth, so that no splinters can escape through the pressure relief 60 to the outside in the event of an explosion.

In the example shown, the depression 110 is designed to be large enough for the ordnance 90 to be placed in a transport container 120 and divided up in it. For this purpose, a cutting device 70 and a chamber lifting device 80 are also arranged in the depression. The chamber lifting device 80 can, in particular, spend ammunition parts cut off by the cutting device 70 in a cardboard box 130, wel surface are arranged on a shelf 100 above the depression 110.

2 shows a buoyant delaboration platform 200. This has a buoyant platform 210, for example a pontoon. In a first platform area 250, two delaboration chambers 10, 11 are arranged in the example shown. For practical reasons these would rather be placed perpendicular to the image plane. For better representation, however, they are shown here. For example and advantageously, there can also be more delaboration chambers 10, 11, for example four delaboration chambers 10, 11. The first platform area 250 is separated from the second platform area 260 by a protective element 270. The protection element is formed such that one surface is arranged at an angle of 45° to the surface of the second platform area 260 and at an angle of 135° to the surface of the first platform area 250 . If a detonation occurs in a delaboration chamber 10, 11 and the pressure wave of the detonation is not only directed upwards through the inner floor 40, the first chamber area 50 and the pressure relief 60, a pressure wave running horizontally towards the second platform area 260 is Protective element deflected upwards and thus protects the devices arranged in the second platform area 260 .

A combustion device 230 is arranged in the second platform area 260 . This is preferably designed to safely incinerate pieces of ammunition, for example each weighing 10 kg. In the example shown, a gas cleaning system 240 is connected to the combustion device 230 in order to clean the combustion exhaust gases, in particular to filter out or convert chemical warfare agents and their combustion products. In this way, chemical warfare agents 90 can also be reliably and safely destroyed. In order to transport the ammunition parts from the dismantling chambers 10, 11 to the combustion device 230, the buoyant dismantling platform 200 has a transport device 280, for example a conveyor belt. Furthermore, a lifting device 220 is preferably arranged in the second platform area 260, with which ordnance 90 can be lifted out of the water and introduced directly into the delaboration chambers 10, 11. Due to the positioning of the lifting device 220 in the second platform area 260, the base of the lifting device 220 is also protected by the protective element 270, so that in the event of a detonation, precisely when the ordnance 90 is inserted into a delaboration chamber 10, 11, where the danger is greatest, only a small and easily repairable part of the hoist 220 needs to be repaired or replaced.

Furthermore, the buoyant dismantling platform 200 can have a third platform area, which is arranged behind the second platform area 260 and is separated from it by a further protective element 270 . As a result, this area is the best protected area, so that quarters 290 for the crew can be arranged here, for example. Other system-relevant components (propulsion, communication, radar, possibly sonar for detecting underwater munitions) can preferably be arranged in this area.
