Definitions
- the invention relates to a system for detecting a fault condition in a swimming tube.
- Floating hoses are basically known from the prior art.
- a floating hose is often used to connect one end to a buoyant buoy so that the other end can be used to connect and disconnect to a tanker.
- the floating tube can float in the water of a sea together with the buoy.
- the buoy can also be coupled to an underwater hose.
- a fluid connection between the underwater tube and the flotation tube is established by the buoy. Fluid can thus be directed from the underwater tube through the buoy to the second end of the flotation tube. This can be used, for example, when a fluid, in particular crude oil, is to be routed from the underwater hose to the tanker.
- a reverse flow direction for the fluid in particular the crude oil
- petroleum can be pumped from the tanker through the floating hose to the buoy and then into the underwater hose.
- the second end of the floating hose can be uncoupled from the tanker.
- the swimming tube floats freely in the water of the sea, at least with the second end. It may be a long time, in particular several hours or even days, before another tanker approaches the second end of the floating hose in order to couple the second end of the floating hose.
- the movement of the swimming tube is influenced by the current of the sea water and/or by the wind over the sea water.
- the invention is based on the object of being able to determine a faulty state of a floating hose as quickly and easily as possible and from afar.
- a system for detecting a faulty state of a swimming tube is therefore provided.
- the system has a buoyant swimming tube, a detection system and an evaluation unit.
- the detection system is designed to detect a geometric arrangement of the swimming tube and/or to detect a swimming state of the swimming tube.
- the detection system is configured to generate a detection signal that represents the detected geometric arrangement of the swimming tube and/or the detected swimming state of the swimming tube.
- the detection system and the evaluation unit are coupled via a first signal connection in order to transmit the detection signal from the detection system to the evaluation unit.
- the evaluation unit is configured (a) to detect a first error state of the swimming tube based on the geometric arrangement if tube sections of the swimming tube are arranged crossing one another, (b) based on the geometric arrangement detect a second failure condition of the swim tube when a tube section of the swim tube is disposed detached from the remainder of the swim tube, (c) detect a third failure condition of the swim tube based on the swim condition when a tube section of the swim tube is fully submerged in water, and/or ( d) recognizing a fourth fault condition of the swimming hose based on the geometric arrangement if the swimming hose is arranged wound at least in sections.
- the system allows an automatic and therefore particularly fast detection of a faulty state of the floating hose.
- the system has the swimming tube and the detection system, with the detection system detecting the geometric arrangement of the swimming tube or a swimming state of the swimming tube.
- the swimming state can represent and/or be determined by a draft of the swimming tube.
- the floating hose can have a multiplicity of buoyant hose segments which are arranged one behind the other to form a hose strand and are coupled to one another. This hose strand forms an advantageous embodiment of the floating hose. If the swimming tube has a large number of tube segments, the floating state can represent the draft of each of the tube segments and/or be determined thereby.
- the buoyancy of a tube segment can be positive if this tube segment is arranged at least partially floating above the waterline.
- the buoyancy status of a hose segment can be negative if the respective hose segment is completely below the waterline or is completely submerged in water.
- the floating state of the floating hose can be formed by the floating states for the hose segments.
- the buoyancy of the buoyancy tube may represent the draft for each tube segment.
- the detection system can have an imaging camera to capture an image of the swim tube in the water.
- the detection system can have a processor unit in order to carry out the aforementioned pattern recognition.
- the capture system may also include said camera for capturing an image of the swim tube.
- the floating state of the floating tube can also be detected by another advantageous embodiment of the detection system.
- the detection system can have a plurality of node units, each node unit being designed by means of an associated radio unit to set up a radio connection to two other radio units.
- a radio network can be formed as a result.
- Each or more of the hose segments may have a corresponding node unit and/or the node unit may be attached to the respective hose segment.
- the radio connection from one node unit to another of the node units is only established as long as the node unit and/or an associated antenna of the node unit is above the waterline. Only then can an over-the-air radio link be established. Based on the aforesaid radio network it is therefore possible to identify the radio units that are not part of the radio network.
- the detection system can be designed for a corresponding identification.
- the detection system can thus recognize that the hose segments are floating with a node unit attached to them if the respective radio unit participates in the radio network by setting up a radio connection.
- hose segments whose attached node unit does not establish and/or form a radio connection to the radio network can be recognized by the detection system as a submerged hose segment.
- the detection system can know what number of node units is provided for the swimming tube and which of the tube segments the respective node unit is assigned to.
- the detection system can therefore be designed to to detect the submerged hose segments based on the radio connections of the radio network and to recognize the associated hose segments as submerged.
- the node units participating in the radio network and the associated hose segments are therefore recognized by the detection system as floating hose segments.
- the detection system can therefore detect a flotation condition of the flotation tube, with the flotation condition representing each of the tube segments as either floating or fully submerged.
- a geometric arrangement of the swimming hose can be understood to mean, for example, a spatial structure and/or a spatial arrangement of the swimming hose.
- the geometric arrangement can be determined and/or represented, for example, by spatial coordinates, for example in a plane, of the swimming tube.
- the geometric arrangement can be determined and/or represented, for example, by spatial coordinates, preferably in one plane, of the tube segments.
- the geometric arrangement can also relate, for example, to the spatial orientation of the swimming hose and/or the preferably associated hose segments.
- the geometric arrangement of the floating hose can therefore provide information about how and/or in which geometric form the floating hose is arranged.
- the detection system is at least partially attached to the flotation tube.
- the detection system can be partially embedded in the swimming tube.
- the node units can be at least partially embedded in a jacket wall of each of the floating tubes.
- the permanent coupling of the detection system to the swimming hose is not absolutely necessary.
- the detection system is implemented with the optical camera, for example, then the detection system can be fixed, for example, on a buoy that is connected to a first end of the swimming tube. The camera can then be oriented to optically capture the flotation tube.
- the evaluation unit is coupled to the detection system via the signal connection.
- the evaluation unit is also directly mechanically connected to the detection system and/or the evaluation unit and the detection system can be at least partially integrated.
- the evaluation unit can also be attached to the swimming tube and/or the buoy.
- the evaluation unit is spatially separated from the detection system. It is preferably provided that the evaluation unit is physically and spatially separated from the detection system.
- the evaluation unit can be arranged on land or on a ship.
- the first signal connection between the detection system and the evaluation unit can be designed partially or completely as a wireless signal connection, in particular a radio signal connection. This offers the advantage that the detection of the faulty state of the floating tube can also be carried out particularly quickly by means of the evaluation unit with a particularly high computing power.
- the evaluation unit can be implemented by a computer cloud network. However, this is only one advantageous configuration option.
- the first signal connection can take place, for example, via a satellite and/or other communication nodes.
- the first signal connection can be made via a satellite and from there via other satellites to a land station, from which the first signal connection leads via cable to the evaluation unit.
- the detection signal is transmitted from the detection system to the evaluation unit via the first signal connection.
- the evaluation unit therefore has information about the geometric arrangement of the swimming tube and/or the swimming state of the swimming tube.
- the evaluation unit is configured to recognize the first error status, the second error status, the third error status and/or the fourth error status.
- the evaluation unit can therefore be configured, for example, to recognize only one of the error states mentioned above. However, it is also possible for the evaluation unit to be designed to recognize several of the error states mentioned above.
- the evaluation unit is configured to detect each of the error states mentioned above.
- the following is the configuration of the evaluation unit in connection with each of the above Error states are explained individually. However, this should not necessarily mean that only one of the configurations explained may be provided for the evaluation unit. In principle this is possible. However, it can also be provided that several of the configurations explained above and/or all of the configurations explained below can be provided for the evaluation unit.
- the geometric arrangement relates to the geometric arrangement of the swimming tube detected by the detection system.
- the evaluation unit has the corresponding information, since the evaluation unit is coupled to the detection system via the first signal connection and the detection signal can be transmitted to the evaluation unit via this.
- the geometric arrangement of the swimming tube can represent the geometric shape and/or the spatial arrangement of the swimming tube. If the geometric shape of the swimming hose is designed in the manner of a loop, for example, then there are at least two hose sections and/or two hose segments which are arranged crossing one another. Each hose section can be formed by a single hose segment. However, it is also possible for one or each of the hose sections to be formed by a plurality of hose segments of the floating hose.
- the crossing arrangement of the hose sections of the swimming hose can occur, for example, when the swimming hose forms the loop and thus a hose section of the swimming hose rests on another hose section of the swimming hose.
- the two tube sections do not necessarily have to be arranged at an angle of 90 degrees to one another.
- the hose sections can be arranged at an acute angle and/or at a shallow angle relative to one another.
- Tube sections arranged crossing one another can be recognized by the evaluation unit based on the geometric arrangement of the floating tube.
- the evaluation unit can be configured accordingly for this purpose.
- Crossing hose sections of a floating hose are to be avoided as far as possible, since the crossing hose sections are exposed to a particularly high mechanical load when the floating hose is used.
- the geometric arrangement of the swimming tube can therefore be incorrect, since it includes tube sections that cross one another. A first fault condition is therefore recognized by the evaluation unit for this swimming tube.
- the evaluation unit is configured to recognize a second error state of the swimming hose based on the geometric arrangement if a hose section of the swimming hose is arranged detached from the rest of the swimming hose.
- the geometric layout is the geometric layout of the swim tube that is sensed by the sensing system. If a hose section detaches from the rest of the swimming hose, the geometric arrangement of the swimming hose will also represent the greater distance between the severed hose section and the remaining hose that has arisen as a result of the severing.
- the evaluation unit can be stored by the evaluation unit as to which maximum sections may exist between the hose segments and/or between hose sections of the swimming hose. If the distance between two of the hose segments and/or hose sections mentioned is greater than the corresponding maximum distance, this can be recognized by the evaluation unit based on the geometric arrangement and preferably based on the stored maximum distance between the hose segments and/or hose sections. The evaluation unit is preferably configured accordingly for this purpose. If the maximum distances are the same, a single maximum distance can be used instead of the maximum distances mentioned above.
- the evaluation unit can also be configured to determine the second fault condition of the swimming tube based on the geometric arrangement of the entire swimming tube and the maximum distance between the tube segments.
- a detached hose section can also be recognized from the remaining hose section of the swimming hose based on the angle between the severed part of the hose section and the remaining hose section. Because usually the hose sections can only be arranged at a limited angle relative to one another. This angle can be stored by the evaluation unit as a limit value angle. If the angle represented by the geometric arrangement between the severed hose section and the remaining hose section is greater than the predetermined limit value angle, this can be recognized by the evaluation unit and the second error state of the floating hose can then be recognized. A combination of the above options is also possible.
- the evaluation unit can be configured accordingly for this purpose.
- the evaluation unit is configured to recognize a third error state of the swimming hose based on the swimming state when a hose section of the swimming hose is completely immersed in water.
- the swimming state can refer to the entire swimming tube as a unit and/or that the swimming state of the swimming tube can represent the respectively associated swimming state for each tube segment of the swimming tube.
- the swimming state can assume a respective value that indicates whether the respective hose segment is floating or completely submerged.
- a swimming state for the entire swimming tube can be generated from the individual swimming states of the tube segments.
- the detection system can be designed and/or configured accordingly.
- the evaluation unit can therefore recognize whether a hose section of the swimming hose is completely immersed in water.
- the hose section can be formed by a single hose segment of the floating hose. However, it is also possible for the hose section to be formed by a plurality of hose segments of the floating hose. Total immersion of the tube section in the water may occur, for example, at the second end of the flotation tube, with the opposite first end of the flotation tube being attached to a buoy.
- the second end of the swimming hose and the hose section of the swimming hose adjoining it can, for example, be immersed in the water if the second end of the swimming hose has a defect and/or fault.
- a valve is arranged at the second end of the swimming tube in order to close the second end of the swimming tube, an incorrectly opened valve can lead to water penetrating into the interior of the swimming tube and thus causing the second end of the swimming tube to be submerged and/or at least encourages.
- a tube section of the floating tube may submerge. For example, if said hose section of the floating hose was run over by a large ship or if the hose section collided with a ship, the hose section may be damaged, causing the hose section to be immersed in the water.
- the section of hose submerged in the water need not necessarily be at one end of the swim hose.
- the evaluation unit can identify the tube segments that are completely immersed in the water are immersed. Based on this, the evaluation unit can therefore recognize the hose section that is completely immersed in the water. If this was recognized by the evaluation unit, the third error state of the floating hose is recognized by the evaluation unit. Provision can preferably be made for the evaluation unit to positively identify the third error state only when the hose section of the floating hose is completely immersed in water for at least a predetermined period of time.
- the evaluation unit is configured to recognize a fourth fault condition of the swimming hose based on the geometric arrangement if the swimming hose is arranged wound at least in sections.
- the geometric arrangement relates to the geometric arrangement of the swimming tube detected by the detection system. This corresponding information is available to the evaluation unit.
- the flotation tube is often attached to a buoy at a first end. The second end of the swimming tube can be moved around the buoy by the water current and/or the wind, so that one or more windings of the swimming tube are formed around the buoy.
- the floating tube is preferably arranged in a coiled manner when at least one complete turn of the floating tube is formed around an object.
- the geometric arrangement of the swim tube can represent the geometric shape of the swim tube.
- the evaluation unit can be configured by winding the swimming tube based on the geometric arrangement of the swimming tube. If the evaluation unit recognizes the winding of the swimming tube, it also recognizes the fourth error status of the swimming tube.
- the evaluation unit can be configured to carry out pattern recognition based on the geometric arrangement or the swimming state of the swimming tube. If corresponding patterns are recognized by the evaluation unit, the pattern recognized in each case can be assigned to one of the error states mentioned above.
- the evaluation unit can therefore preferably be designed and/or configured to recognize one or each of the error states by means of pattern recognition.
- the floating hose has a plurality of hose segments that are coupled to one another in series.
- the coupling is preferably a mechanical coupling.
- the tube segments can therefore be arranged one behind the other and connected to one another in a non-positive and/or positive manner at their end faces, so that a strand of tube segments is formed. This can also be referred to as a hose line and/or form the floating hose.

In particular, it is possible for at least one part of the detection system to be assigned to each hose segment of the swimming hose and/or to be attached to the respective hose segment. As a result, a particularly precise detection of the geometric arrangement of the floating tube is possible.
- An advantageous embodiment of the system is characterized in that the system has a floatable buoy, with a first end of the floating hose being connected to the buoy. This is preferably a mechanical connection.
- the first end of the swimming tube can therefore be connected to the buoy in a non-positive and/or positive manner.
- a fluid connection between the swimming tube and the buoy can also be established as a result.
- the buoy can also have another connector.
- An underwater hose can be coupled to the buoy with this connection. This can also be a non-positive and/or positive connection.
- the underwater hose can establish a fluid connection to the buoy through said connection.
- a fluid connection between the underwater hose and the swimming hose can be established by means of the buoy.

- the radio connections between the plurality of node units thus form a radio network which enables communication with each of the node units. If the radio connection of one of the node units to the radio network is interrupted, this can be detected by the detection system.
- the detection system can be designed and/or configured for this.
- the detection system can identify the hose segment or the hose section of the floating hose to which the respective node unit is attached, to which the radio connection is interrupted.

- the detection system 6 is therefore designed to detect the geometric arrangement of the swimming tube 4 .
- the main unit 26 can therefore use the radio connections 22 and/or the radio network 24 to detect whether a direct or indirect radio connection 22 can be established with each of the other node units 20 . If no direct or indirect radio connection 22 is possible from the main unit 26 to one of the other node units 20 , the main unit 26 can be configured to determine the respective node unit 20 as a submerged node unit 20 . Because in practice it was found that the radio link 22 is interrupted as soon as the respectively associated node unit 20 is completely immersed in water.
- the main unit 26 can therefore use the radio connections 22 or the radio network 24 to detect which of the hose segments 16 is immersed and which of the hose segments 16 is floating.
- a flotation condition of the swim tube 4 may indicate which of the tube segments 16 of the swim tube 4 are floating and/or which tube segments 16 of the swim tube 4 are fully submerged. Since the Since the respective floating state of each of the tube segments 16 can be detected by the main unit 26 , the main unit 26 is also designed to detect the floating state of the floating tube 4 .

- the main unit 26 and each of the node units 20 are preferably formed as one electrical unit. They therefore require electrical energy for operation.

- a continuous, quasi-continuous or periodic detection of the geometric arrangement of the swimming tube 4 can be achieved by selecting the time intervals between the detection times of the geometric arrangement or the swimming state. The same applies to the transmission of the information by means of the detection signal via the first signal connection 14.
- the evaluation unit 8 can therefore have the corresponding information about the geometric arrangement and/or the swimming state of the swimming tube 4 available continuously, quasi-continuously or periodically. With each update of the geometric arrangement of the swimming tube 4 and/or the swimming state of the swimming tube 4, the evaluation unit 8 can carry out a new check of this information for a possible error state of the swimming tube 4.
- the evaluation unit 8 is preferably configured accordingly for this purpose.
- the evaluation unit 8 is preferably configured to recognize a first error state of the swimming hose 4 based on the geometric arrangement of the swimming hose 4 when hose sections 12 of the swimming hose 4 are arranged crossing one another.
- the evaluation unit 8 can be configured to recognize tube sections 12 of the floating tube 4 that are arranged crossing each other based on the geometric arrangement of the floating tube 4 .
- FIG. 2 Another advantageous embodiment of the system 2 with a floating hose 4, a detection system 6 and an evaluation unit 8 is shown in FIG.
- the system 2 also has a buoy 18 .
- the system 2 corresponds at least in Essentially the system 2 explained in relation to FIG. 1, but the system 2 shown in FIG. 2 has a larger number of tube segments 16 which are coupled to one another in series. Due to the length of the resulting floating tube 4, it can happen that the second end 30 of the floating tube 4 is lifted over a tube section 12 between the two ends 28, 30 of the floating tube 4. This can occur when there is a very large swell in the water of the sea.
- a hose segment 16 lies on top of another hose segment 16.
- each of the two hose segments 16 mentioned can form a hose section 12 of the swimming hose 4, which intersects are arranged to each other.
- a coupling area between two tube segments 16 it is also possible for a coupling area between two tube segments 16 to be arranged above a further tube segment 16 .
- the hose section that is arranged on the other hose segment 16 can form a corresponding hose section 12 of the floating hose 4 .
- a crossing arrangement of hose sections 12 of the floating hose 4 is not limited to a right-angled arrangement of the two hose sections 12 of the floating hose 4 . Rather, it can also happen that the two hose sections 12 are arranged at any other angle, in particular a flat angle or an acute angle, relative to one another.
- Crossing hose sections 12 of the swimming hose 4 thus occur, for example, when the swimming hose 4 is arranged geometrically in the manner of a loop. Due to the intersecting hose sections 12 of the floating hose 4, high mechanical loads can arise, in particular on the hose sections 12 of the floating hose 4 mentioned. It is therefore to be avoided that this floating tube 4 is used to guide a fluid through the floating tube 4 .
- the evaluation unit 8 Based on the geometric arrangement of the floating hose 4 detected by the detection system 6 and based on the transmission of this geometric arrangement by means of the detection signal via the first signal connection 14 to the evaluation unit 8, the evaluation unit 8 can detect a first error state of the floating hose 4 if the geometric arrangement has at least two hose sections 12 des Swim hose 4 represents, which are arranged crossing each other.
- the evaluation unit 8 can be configured based on the geometric arrangement and by means of pattern recognition, which the evaluation unit 8 can carry out. Other configurations of the evaluation unit 8 are also possible.
- the evaluation unit 8 can be trained by means of an artificial neural network to recognize crossing tube sections 12 of the swimming tube 4 based on the geometric arrangement.
- FIG. 3 shows a further advantageous embodiment of the system 2 in a schematic side view.
- the system 2 essentially corresponds to the system 2 as explained in connection with FIG. Reference is therefore made to the corresponding explanations in an analogous manner.
- the evaluation unit 8 of the system 2 is preferably designed to recognize a second error state of the swimming hose 4 based on the geometric arrangement of the swimming hose 4 if a hose section 12 of the swimming hose 4 is arranged detached from the rest of the swimming hose 4 .
- FIGS. 1 and 3 show that the hose segments 16 arranged at the second end 30 of the floating hose 4 form a hose section 12 which is separate from the remaining hose sections 12 of the floating hose 4 .
- the separated hose section 12 has a distance D 1 to the remaining swimming hose 4 , in particular to the hose segment 16 which forms the last hose segment 16 starting from the first end 28 of the swimming hose 4 .
- FIG. 3 also shows an advantageous embodiment of the detection system 6 .
- each tube segment 16 is assigned exactly one node unit 20 .
- the main unit 26 can establish a radio connection 22 to each of the node units 20 . These radio connections 22 are not shown in FIG. 3 for a better overview.
- the node unit 20 is one of the hose segments 16 of the detached hose section, a distance D2 from the node unit 20 of the last hose segment 16 of the remaining hose segments 16 of the swimming hose 4, this distance D2 being greater than would be necessary for a fixed connection between the hose segments 16 to ensure an uninterrupted fluid channel through the hose segments 16.
- the relative distances recorded based on the radio connections 22 can be used to determine that the node units 20 of the last hose segment 16 of the remaining hose segments 16 and the node unit 20 of the first hose segment 16 of the detached hose section 12 are at a distance Dl from one another that is greater than one is the maximum permissible distance that ensures a firm connection between these two tube segments 16 for establishing a fluid connection.
- the evaluation unit 8 can therefore recognize from the geometric arrangement of the floating hose 4 whether at least one hose section 12 has a distance D1 to the rest of the floating hose 4 that is greater than a predetermined permissible distance.
- the evaluation unit 8 can therefore also be configured in such a way, based on the geometric arrangement of the swimming tube 4 , to recognize a second error state of the swimming tube 4 when the tube section 12 of the swimming tube 4 is arranged detached from the rest of the swimming tube 4 .
- a detached portion 12 of the flotation tube 4 not only prevents a safe fluid connection for pumping fluid through the flotation tube 4, but the detached portion 12 of the hose can also pose a hazard to other vessels navigating the waters of the sea.
- the detection of the second error state is therefore particularly important in order to ensure safe operation of the system 2.
- FIG. 4 shows an advantageous embodiment of the system 2, which at least essentially corresponds to the system 2 that has been explained in connection with FIG. Reference is therefore made in an analogous manner to the corresponding explanations, preferred features and/or technical effects.
- the radio links 22 are represented by dashed lines, which each of the node units 20 establishes in particular with the main unit 26 . However, this does not apply to the two knot assemblies 20 attached to the tubing segments 16 which are submerged in the water. Due to these missing radio connections 22 to the submerged node units 20, the main unit 26 can recognize that the last two tube segments 16 at the second end 30 of the floating tube 4 are completely submerged in the water.
- the main unit 26 can detect which of the hose segments 16 are immersed, namely the hose segments 16 of the correspondingly immersed hose section 12. In addition, the main unit 26 can recognize that the remaining hose segments 12 are floating. Based on this information, the main unit 26 and thus also the detection system 6 can detect a tube condition of the swimming tube 4 . In the case shown in FIG. 4, this hose state represents the hose segments 16 of the diving swimming section 12 as diving and the remaining hose segments 16 as floating.
- the swimming state of the swimming tube is preferably represented by the detection signal, which is transmitted to the evaluation unit 8 by means of the first signal connection 14 from the detection system 6 or the associated main unit 26 with the likewise preferred communication unit 34 .
- the evaluation unit 8 can therefore have information about the swimming state of the swimming tube 4 .
- the detection system 6 can also be designed for the periodic detection of the floating state of the swimming tube 4 . With each detection of the swimming state, a corresponding detection signal can be generated by the detection system 6 and transmitted to the evaluation unit 8 . In practice, however, it can happen that a hose segment 16 is submerged in water for a short time, although it is not damaged.
- the detection system 6 can therefore be designed so that a hose section 12 is only detected as submerged if the radio link 22 to the associated first node unit 20 for at least one predetermined period of time is interrupted.
- This period of time is preferably selected and/or predetermined in such a way that an erroneous detection of the floating state of the floating tube 4 does not occur, at least essentially.
- a particularly low error rate when detecting the floating state of the floating tube 4 can be achieved by the aforementioned measure.
- the evaluation unit 8 is also configured to recognize a third error state of the swimming tube 4 based on the swimming state of the swimming tube 4 when at least a section 12 of the swimming tube 4 is completely immersed in the water. If a corresponding error state was recognized by the evaluation unit 8, this information can be passed on by the evaluation unit 8, in particular to the monitoring system. In particular, the third error status can be shown on a display of the monitoring system and/or other measures can be taken based on the detection of the third error status.
- FIG. 5 A further advantageous embodiment of the system 2 is shown in FIG. 5 in a schematic plan view.
- the system 2 essentially corresponds to the system 2 as explained in connection with FIG.
- the floating tube 4 shown in Figure 5 has a larger number of tube segments 16 which are coupled to one another in series to form a floating tube from a first end 28 of the floating tube 4 uninterrupted to a second end 30 of the floating tube 4.
- several tube segments 16 can thereby be arranged laterally to one another.
- the tube segments 16 are connected to one another at their respective end faces in such a way that an uninterrupted and fluid-tight fluid channel is formed by the floating tube 4 .
- the connections at the end faces of the hose segments 16 can be under great mechanical stress. The mechanical stresses can be all the greater, the tighter the floating tube 4 is wound around the buoy 18 . In principle, therefore, a winding of the floating hose 4 should be avoided. In particular, winding the swimming tube 4 around a buoy 18 should be avoided.
- radio links 22 can be established between the node units 20 and in particular from the main unit 26 to each of the node units 20 .
- the radio links 22 are not shown in FIG.
- the detection system 6 can be designed accordingly for this purpose.
- the detection system 6 can detect the geometric shape of the swimming tube 4 as a result of the relative distances. This can represent the coiled shape of the swimming tube 4, for example.
- the geometric arrangement which is represented in particular by the geometric shape of the swimming tube 4, can therefore be used to infer a possible error condition, namely the fourth error condition, if the geometric shape represents a winding of the swimming tube 4, so that the swimming tube 4 is arranged at least partially wound. Therefore, the evaluation unit 8 is based on the Geometric arrangement of the swimming tube 4 is also configured to detect a fourth fault condition when the swimming tube 4 is at least partially wound and/or coiled. The evaluation unit 8 can also be configured to detect a coiled and/or twisted section of the swimming tube 4 . This coiled and/or coiled configuration can be represented and/or derived from the geometric configuration. Due to the configuration of the evaluation unit 8, the fourth error state can therefore be inferred based on the geometric arrangement.
- the evaluation unit 8 can have stored a corresponding pattern recognition and/or be designed in such a way that a pattern recognition can be carried out based on the geometric arrangement of the swimming tube 4, with the pattern recognition being designed to recognize a coiled and/or twisted section of the swimming tube 4 . Therefore, if a coiled and/or twisted section of the swimming tube 4 was recognized by means of the pattern recognition, the evaluation unit will thereby recognize the fourth error state.
- the evaluation unit 8 can be configured to detect each of the four error states of the swimming tube 4 explained above. However, it is also possible for the evaluation unit 8 to be designed to detect one of the error states, namely one of the first, second, third and/or fourth error states. For example, the evaluation unit 8 can be designed to detect the first and third error states. Another combination is also possible.
- FIG. 6 A further advantageous embodiment of the system 2 is shown in FIG. This is a top view of the system 2 as shown in FIG.
- the floating hose 4 is referred to as the first floating hose 36 .
- the first flotation tube 36 therefore extends from a first end 28a to a second end 30a.
- the first flotation tube 36 includes a plurality of tube segments 16 coupled together in a series coupled to form a continuous, fluid-tight fluid passage from the first end 28a to the second end 30 .
- the first end 28a of the first Swim tube 36 is coupled to buoy 18 .
- the system 2 has another, namely a second, floating hose 38 .
- the second floating tube 38 can be designed analogously to the first floating tube 36 .
- the second flotation tube 38 includes a plurality of tube segments 16 coupled together in series to form an uninterrupted, fluid-tight fluid conduit from a first end 28b of the second flotation tube 38 to a second end 30b of the second flotation tube 38 .
- the node units of the first swimming tube 36 are identified by the reference numerals 20a.
- the node units of the second swimming tube are identified by the reference numerals 20b.
- the detection system 6 can be designed to detect a geometric arrangement of the at least one swimming tube 4, in particular the two swimming tubes 36, 38.
- the detection system 6 can be designed to detect a swimming state of the at least one swimming tube 4, in particular the first and second swimming tube 36, 38.
- the detection system can be configured to generate a detection signal that represents the geometric arrangement of the at least one swimming tube 4, in particular the two swimming tubes 36, 38, and/or the detected swimming state of the at least one swimming tube 4, in particular the two swimming tubes 36, 38 .
- the evaluation unit 8 can be configured to recognize a first error state of the at least one swimming hose 4, in particular the two swimming hoses 36, 38, based on the geometric arrangement of the at least one swimming hose 4, in particular the two swimming hoses 36, 38, if hose sections 12 of the at least one swimming hose 4, in particular a hose section 12 of each of the swimming hoses 36, 38, are arranged crossing one another.
- the evaluation unit 8 can be configured based on the geometric arrangement of the first and second swimming hose 36, 38 to detect a first error state of the two swimming hoses 36, 38 when a hose section 12 of the first swimming hose 36 is arranged crossing a further hose section 12 of the second swimming hose 38.
