Definitions
- the invention relates to a system and a method for recovering a submarine vehicle, in particular an unmanned submarine vehicle.
- Such a submarine vehicle is generally transported by means of a marine vessel to a place of use and at that point let into the water from on board the marine vessel or from the land, for example from a jetty. After carrying out its mission, the submarine vehicle has to be recovered again. To this end, it is known to reel in the free end of a rope fastened to the submarine vehicle and to pull in and retrieve the submarine vehicle onto the marine vessel by means of the rope.
- a known system for recovering a submarine vehicle comprises a recovery ramp, by means of which the submarine vehicle is retrieved on board the marine vessel from the body of water.
- the recovery ramp is fixed relative to the marine vessel for recovering the submarine vehicle, such that the recovery ramp protrudes obliquely into the water from the deck of the marine vessel so that the submarine vehicle is able to be pulled onto the recovery ramp by means of the rope in the region of the waterline and/or water surface of the body of water.
- the marine vessel comprising the recovery ramp has a considerably greater volume and a considerably greater mass relative to the submarine vehicle.
- the position of the marine vessel in the water therefore, is substantially influenced by heavy seas and/or waves of relatively long wavelength.
- the submarine vehicle follows comparatively small waves which leave the marine vessel substantially unaffected.
- the recovery ramp crashes up and down, in particular relative to the submarine vehicle, and thus can hit the submarine vehicle hard and damage said submarine vehicle during the recovery procedure, in particular in the front part of the submarine vehicle.
- the recovery ramp itself can be damaged thereby. Even if the recovery ramp is arranged in a fixed manner, for example on the jetty, the submarine vehicle can hit the recovery ramp hard due to the waves.
- DE 195 00 182 C2 discloses a device for retrieving a trailing body pulled underwater on a trailing cable via a carriage, which is displaceable on vertically arranged guide rails, with a pivotable support arm.

Description
- The present invention is the US national stage under 35 U.S.C. §371 of International Application No. PCT/EP2012/064152, which was filed on Jul. 19, 2012 and which claims the priority of
application DE 10 2011 109 092.8 filed on Aug. 1, 2011 the content of which (text, drawings and claims) are incorporated here by reference in its entirety. - The invention relates to a system and a method for recovering a submarine vehicle, in particular an unmanned submarine vehicle. The submarine vehicle can be an autonomous submarine vehicle (AUV=Autonomous Underwater Vehicle), but alternatively can also be a submarine vehicle operated by cable (ROV=Remotely Operating Vehicle).
- Such a submarine vehicle is generally transported by means of a marine vessel to a place of use and at that point let into the water from on board the marine vessel or from the land, for example from a jetty. After carrying out its mission, the submarine vehicle has to be recovered again. To this end, it is known to reel in the free end of a rope fastened to the submarine vehicle and to pull in and retrieve the submarine vehicle onto the marine vessel by means of the rope. A known system for recovering a submarine vehicle comprises a recovery ramp, by means of which the submarine vehicle is retrieved on board the marine vessel from the body of water. The recovery ramp is fixed relative to the marine vessel for recovering the submarine vehicle, such that the recovery ramp protrudes obliquely into the water from the deck of the marine vessel so that the submarine vehicle is able to be pulled onto the recovery ramp by means of the rope in the region of the waterline and/or water surface of the body of water.
- The marine vessel comprising the recovery ramp has a considerably greater volume and a considerably greater mass relative to the submarine vehicle. The position of the marine vessel in the water, therefore, is substantially influenced by heavy seas and/or waves of relatively long wavelength. However, the submarine vehicle follows comparatively small waves which leave the marine vessel substantially unaffected. As a result, in moderate and/or heavy seas this leads to a vertical relative movement of the submarine vehicle relative to the recovery ramp. The recovery ramp crashes up and down, in particular relative to the submarine vehicle, and thus can hit the submarine vehicle hard and damage said submarine vehicle during the recovery procedure, in particular in the front part of the submarine vehicle. In addition, the recovery ramp itself can be damaged thereby. Even if the recovery ramp is arranged in a fixed manner, for example on the jetty, the submarine vehicle can hit the recovery ramp hard due to the waves.
- Devices for picking up watercraft and/or boats are disclosed in DE 195 00 182 C2, U.S. Pat. No. 2,371,461 A, WO 2008/025345 A1 and U.S. Pat. No. 4,242,768 A, in each case the devices not being pulled by means of a rope. DE 38 34 174 C2 and EP 1 216 918 A8 also propose such devices for picking up submerged objects. DE 41 40 201 C2 discloses a device for retrieving a trailing body pulled underwater on a trailing cable via a carriage, which is displaceable on vertically arranged guide rails, with a pivotable support arm.
- The object of the invention is to improve the recovery of a submarine vehicle, in particular to configure the recovery process to be safer for the submarine vehicle.
- In various embodiments, the invention achieves this object by a system for recovering a submarine vehicle according to
Claim 1 and by a method for recovering a submarine vehicle according toClaim 8. The system of the type mentioned in the introduction has a wave compensation ramp pivotably mounted on the recovery ramp about a pivot axis relative to the recovery ramp and supported by a floating body for receiving the submarine vehicle and for retrieving the wave compensation ramp together with the received submarine vehicle by means of the recovery ramp, in particular on board the marine vessel or on land, in particular on a jetty. The wave compensation ramp has an end which opposes the pivot axis and/or which is free, the floating body can be arranged on the free end. In various embodiments, the system also comprises the rope for pulling the submarine vehicle. - Due to the floating body, the wave compensation ramp is adapted to the position of the waterline and/or water surface and/or to the waves. In particular the wave compensation ramp at its free end is adapted to the movement of the submarine vehicle so that the submarine vehicle and the free end of the recovery ramp are both located approximately in the region of the waterline. A front and/or rear floating body can be provided as floating bodies. Alternatively or additionally, further floating bodies can be provided.
- The pivot axis can be arranged in the region, in particular up to half a meter, above an average waterline and/or just above the region in which the waterline is located in calm seas. The recovery ramp, therefore, only needs to extend down almost as far as the average waterline and not be immersed further into the water. As a result, the recovery ramp can be configured to be shorter relative to the known recovery ramp cited in the introduction. The recovery ramp of the system according to various embodiments of the invention can be accommodated, therefore, in a space-saving manner on board the marine vessel or on land, for example on a truck or in a container. According to various embodiments of the method, the submarine vehicle is received by means of the wave compensation ramp and subsequently the wave compensation ramp together with the received watercraft are retrieved by means of the recovery ramp.
- The system according to various embodiments of the invention is also suitable and provided for launching the submarine vehicle. According to various embodiments of the method, the wave compensation ramp is lowered together with the submarine vehicle over the recovery ramp so that the submarine vehicle slides over the recovery ramp into the water. To this end, the wave compensation ramp remains fully mounted on the recovery ramp and/or does not need to be extended or does not need to be fully extended.
- According to various embodiments, the system comprises a guide carriage which is displaceable in a linear manner on the recovery ramp, with a joint for mounting the wave compensation ramp. The joint thus provides the pivot axis. By displacing the guide carriage, the height at which the wave compensation ramp is mounted can be altered. By means of the guide carriage, the wave compensation ramp can be lifted up or lowered onto the recovery ramp. According to various embodiments of the method, the guide carriage is displaced in a linear manner on the recovery ramp, the joint mounting the wave compensation ramp.
- In various embodiments, the system comprises a hydraulically driven belt drive for displacing the guide carriage. The belt drive provides the tensile force for lifting and lowering the wave compensation ramp, in particular together with the submarine vehicle received by the wave compensation ramp. According to various embodiments of the method, the belt drive displaces the guide carriage.
- According to various embodiments, the system comprises a front receiver device which is displaceable in a linear manner on the wave compensation ramp, for guiding the rope and for guiding, and can also be for mounting, the submarine vehicle. According to various embodiments of the method, the front receiver device is displaced in a linear manner on the recovery ramp, the front receiver device guiding the rope and/or the submarine vehicle. In particular, the rope is threaded through the front receiver device for retrieving the submarine vehicle. Subsequently, the submarine vehicle is pulled towards the front receiver device and onto the wave compensation ramp, in particular by means of a winch, the front receiver device being displaced on the wave compensation ramp and guiding the submarine vehicle.
- According to various embodiments, the system comprises coupling means for coupling to a front attachment fastened to the submarine vehicle. Thus, the submarine vehicle is coupled via the front attachment to the receiver device, according to various embodiments of the method the coupling means being coupled to the front attachment.
- According to various embodiments, the system comprises the front floating body for retaining the front receiver device in the region of the waterline of the body of water during the coupling procedure. According to various embodiments of the method, the front floating body retains the front receiver device in the region of the waterline of the body of water. Thus, the vertical relative movements of the coupling means are minimized relative to the submarine vehicle. The coupling is simplified.
- According to various embodiments, the coupling means comprise a snap connection device for engaging and retaining the front attachment. The snap connection device can be designed with a locking pawl. The snap connection engages the front attachment and subsequently fixedly retains the front attachment and thus the submarine vehicle so that the submarine vehicle is able to be guided by means of the front receiver device and mounted by the front receiver device. The snap connection device permits automatic engagement, with subsequent secure retention of the front attachment and/or the submarine vehicle.
- Advantageously, the front receiver device comprises a negative shell for centering the submarine vehicle. The negative shell centers the submarine vehicle, in particular relative to the front receiver device and thus, relative to the longitudinal axis of the wave compensation ramp. Thus, the negative shell assists the engagement by means of the snap connection device and also the retention and mounting of the front attachment and/or the submarine vehicle.
- According to various embodiments, the negative shell comprises two, or more than two, guide strips when moving the negative shell to the free end of the wave compensation ramp, in particular forming a guide funnel, for guiding the submarine vehicle during the coupling procedure, in particular for guiding the front attachment to the front receiver device and/or for guiding the front attachment to the coupling means and for retaining the submarine vehicle in position. According to a variant, the guide strips are arranged in a plane, for example in the horizontal plane, and thus, spread apart to the side. As a result, a two-dimensional guide funnel is formed for the submarine vehicle. The guide strips can be flexible and comprise floating bodies, in particular where the guide strips are spread apart to the side in the horizontal plane. As a result, the guide strips are adapted to the surface of the body of water.
- According to various embodiments the guide strips, in particular more than two guide strips, are arranged in a radial and/or rotationally symmetrical manner about an axis, along which the front receiver device is displaceable on the wave compensation ramp so that the spread-apart guide strips form a three-dimensional guide funnel. In any case, the spread-apart guide strips guide the submarine vehicle through the rear receiver device and at the same time center the submarine vehicle. In this case, the guide strips are passed through the rear receiver device. When the front receiver device is located in the region of the rear receiver device and/or in the region of the free end of the wave compensation ramp, the guide strips are spread apart. If, however, the front receiver device is retracted, the guide strips are held together by the rear receiver device in a more compact manner relative thereto. When extending the front receiver device with the negative shell, the guide strips spread apart, for example by means of the force of springs. The guide funnel is opened. However, when retracting the front receiver device, in particular together with the submarine vehicle coupled thereto, the guide funnel is closed and retains the submarine vehicle in position, in particular relative to the front receiver device.
- According to various embodiments, the system comprises a rear receiver device fastened to the wave compensation ramp, in particular for guiding and mounting the submarine vehicle. In various implementations, the rear receiver device comprises the rear floating body for retaining the free end of the wave compensation ramp in the region of the waterline of the body of water. In particular, the rear floating body of the rear receiver device and the front floating body of the front receiver device jointly ensure that the front receiver device and the wave compensation ramp together adopt an advantageous position for coupling and for pulling onto the wave compensation ramp.
- According to various embodiments, the rear receiver device comprises wheels for guiding and mounting the submarine vehicle. The wheels can be arranged such that they come into contact with robust portions of the submarine vehicle and do not come into contact with or damage sensors. In various implementations, the rear receiver device comprises four wheels or alternatively a different number of wheels which limit the freedom of movement of the submarine vehicle along the longitudinal axis of the wave compensation ramp.
- According to various embodiments, the system comprises a guide pulley mounted on the guide carriage or on the wave compensation ramp in the region of the pivot axis for deflecting the rope from the wave compensation ramp to the recovery ramp. In particular, the guide pulley is arranged above the pivot axis and/or the joint, when the recovery ramp is in a position for retrieving the submarine vehicle and/or when the guide carriage is positioned at the free end of the recovery ramp and/or in the region of the average waterline. In particular, the guide pulley is arranged such that when the submarine vehicle is guided on the wave compensation ramp the lifting of the wave compensation ramp is assisted by pulling on the rope. Pulling on the rope thus has a lifting effect on the wave compensation ramp. As a result, a lowering of the wave compensation ramp below the waterline and/or water surface is counteracted. According to various embodiments of the method, the guide pulley accordingly bears the rope.
- According to various embodiments, the system comprises a marine bearing assembly for mounting the recovery ramp on the marine vessel or on land. Moreover, the system can have a tilting roller and a rocker for lifting the recovery ramp via the rocker onto the marine bearing assembly. In various implementations, a plurality of tilting rollers and rockers are provided. As a result, the recovery ramp can be mounted together with the wave compensation ramp and the submarine vehicle on board the marine vessel or on land and lowered by tilting the rocker toward the water or can be lifted on board and/or onto land by means of the rocker via the tilting roller. In various implementations, the marine bearing assembly has a hydraulic cylinder for driving the rocker. The hydraulic cylinder drives the rocker and/or causes the lowering and/or lifting of the recovery ramp by hydraulic means.
- According to various embodiments of the invention, the system comprises an auxiliary rope, by pulling on the auxiliary rope a lowering moment being able to be effected on the wave compensation ramp so that the wave compensation ramp can optionally be lowered counter to the lifting moment effected by means of the rope.
- According to various embodiments, the system on the submarine vehicle comprises the front attachment fixedly connected to the submarine vehicle. Moreover, the rope can be fixedly connected at its first end to the front attachment.
- According to various embodiments, the system comprises a buoy which can be connected and/or is connected to the second end of the rope at least when the rope is not fastened at the second end to a winch of the marine vessel.
- For reeling in the submarine vehicle, the submarine vehicle can launch the buoy, which is retrieved by means of a rope or boat hook from the marine vessel and/or from the land. On board the marine vessel and/or on land, the second end of the rope is threaded through the rear receiver device and through the front receiver device and placed around the guide pulley and fastened to the cited winch on board the marine vessel and/or on land. The winch, which can form part of the system, winds up the rope and/or parts of the rope and thus pulls the submarine vehicle towards the wave compensation ramp and up onto the wave compensation ramp and/or into the wave compensation ramp.
- According to various embodiments, the front receiver device or the rear receiver device or the wave compensation ramp has at least one folding mechanism, but can have two lateral folding mechanisms, and a lower folding mechanism for protecting external sensors of the submarine vehicle. Upon contact of the submarine vehicle with the folding mechanism, the folding mechanism is folded away and/or yields so that a hard impact of the submarine vehicle and/or of sensors of the submarine vehicle against the wave compensation ramp is counteracted.
- Further embodiments are revealed from the claims and from the exemplary embodiments described in more detail with reference to the drawings.

FIG. 8 shows the negative shell according toFIG. 7 with a retained submarine vehicle. - The
FIG. 1 shows asystem 1 configured, in particular, as a recovery device for the recovery of asubmarine vehicle 2 according to various an exemplary embodiments of the invention. Thesubmarine vehicle 2 can be, for example, an autonomous unmanned submarine vehicle which is provided with sensors and is used for carrying out tests below the water surface and/orwaterline 4 of a body ofwater 6 or for carrying out tests on the bed of the body ofwater 6. - The
system 1 comprises amarine bearing assembly 10 which is arranged on board themarine vessel 8, in particular at the stern of themarine vessel 8. Themarine bearing assembly 10 is, for example, fixedly screwed to the deck of themarine vessel 8 by means of screws. Alternatively, themarine bearing assembly 10 is arranged and/or mounted, for example, in a movable manner on the deck of themarine vessel 8. Alternatively, themarine bearing assembly 10 can also be a bearing assembly arranged on land, for example on a jetty. - A
recovery ramp 12 is mounted on themarine bearing assembly 10, the recovery ramp bearing against a tiltingroller 14 fastened to themarine bearing assembly 10. The tiltingroller 14 faces the stern of themarine vessel 8 and/or the water. When themarine bearing assembly 10 is alternatively arranged on land, the tiltingroller 14 also faces the water and/or a jetty wall. Therecovery ramp 12 is connected by afirst end 16 via arocker 18 to themarine bearing assembly 10. Therocker 18 is pivoted toward the stern of themarine vessel 8 and/or toward the water such that a second end and/orfree end 20 of therecovery ramp 12 is arranged in the region of theaverage waterline 4 of the body ofwater 6. Therecovery ramp 12 is thus lowered toward the body ofwater 6. Therecovery ramp 12 is lifted by pivoting therocker 18 via the tiltingroller 14 and, depending on the pivoting direction, thus lowered to thewaterline 4 and/or the water or retrieved on board themarine vessel 8 and/or onto land. To this end, therocker 18 is driven by ahydraulic cylinder 22. Therocker 18 is, for example, mounted on the side of themarine bearing assembly 10 facing the water or, alternatively to the arrangement according toFIG. 1 , on the side remote from the water. - A
wave compensation ramp 24 is pivotably mounted on therecovery ramp 12 about a pivot axis S relative to therecovery ramp 12. In particular, thewave compensation ramp 24 is indirectly connected to therecovery ramp 12 by afirst end 26 via a joint 28 providing the pivot axis S. The joint 28 is arranged on aguide carriage 30 which is able to be displaced in a linear manner on therecovery ramp 12 by means of abelt drive 32 indicated in dashed lines. Thebelt drive 32 can be hydraulically driven. By displacing theguide carriage 30, therefore, thewave compensation ramp 24 can be lowered or therecovery ramp 12 lifted up and/or retrieved. - A second and/or
free end 34 of thewave compensation ramp 24 opposing thefirst end 26 of thewave compensation ramp 24 is supported by a front floatingbody 36 and by a rear floatingbody 38. Arear receiver device 40 fastened to thewave compensation ramp 24 comprises the rear floatingbody 38. The rear floatingbody 38 retains thefree end 34 of thewave compensation ramp 24, in particular with the aid of the front floating body, in the region of thewaterline 4 of the body ofwater 6. Thewaterline 4 changes in moderate and/or heavy seas, thewave compensation ramp 24 adapting its position to thecurrent waterline 4 in the region of thewave compensation ramp 24, in particular in the region of the rear floatingbody 38 and/or the front floatingbody 36. - A
front receiver device 42 comprises the front floatingbody 36 which retains thefront receiver device 42, in particular with the aid of the rear floatingbody 38, in the region of thewaterline 4 of the body ofwater 6. Thefront receiver device 42 has anegative shell 44 in relation to the bow of thesubmarine vehicle 2 which defines a positive shape. The shape of thefront receiver device 42 is thus adapted to the shape of the bow of thesubmarine vehicle 2. Furthermore, thefront receiver device 42 comprises coupling means 46, by means of which thefront receiver device 42 can be coupled to thesubmarine vehicle 2. The coupling is implemented either directly on thesubmarine vehicle 2 but can be indirectly via afront attachment 48 fastened to thesubmarine vehicle 2. Thefront attachment 48 and/or thesubmarine vehicle 2 are in turn directly connected to arope 50 which is shown in dashed lines in the region of thewave compensation ramp 24. Therope 50 is guided through thefront receiver device 42 and through therear receiver device 40. Moreover, therope 50 extends along thewave compensation ramp 24 towards aguide pulley 52 which is mounted above the pivot axis S on theguide carriage 30 and which deflects therope 50 from thewave compensation ramp 24 to therecovery ramp 12. Therope 50 extends further along therecovery ramp 12, optionally via one or more further guide pulleys, not shown, as far as awinch 54 which is able to wind or even unwind therope 50 by electrical drive means. - In the position of the
system 1 and of thesubmarine vehicle 2, shown inFIG. 1 , thesubmarine vehicle 2 has either been let into the water and can now be decoupled or, for example after carrying out a mission, thesubmarine vehicle 2 has been coupled to thefront receiver device 42 and can now be recovered and/or pulled on board themarine vessel 8. - Prior to the decoupling, generally a buoy is launched from the
submarine vehicle 2, to which the free end of therope 50 is fastened, which in the view according toFIG. 1 is fastened to thewinch 54. The buoy is reeled in by means of a ships hook, pulled on board themarine vessel 8 and detached from therope 50. On the deck of themarine vessel 8, the free end of therope 50 is subsequently threaded through thefront receiver device 42 and therear receiver device 40, placed around theguide pulley 52 and finally fastened to thewinch 54. Thewinch 54 now winds up therope 50 and, as a result, pulls thesubmarine vehicle 2 for coupling to thefront receiver device 42. Optionally, in a development of the exemplary embodiment shown, folding mechanisms are arranged on thefront receiver device 42 or on thewave compensation ramp 24, the folding mechanisms counteracting damage to sensors of thesubmarine vehicle 2 when approaching thefront receiver device 42. - As soon as the
underwater vehicle 2 is coupled by means of the coupling means 46 to thefront receiver device 42, therope 50 is hauled in further by means of thewinch 54 which causes thefront receiver device 42 to be displaced along the wave compensation ramp and at the same time, together with the bow and subsequent parts of thesubmarine vehicle 2, to be pushed through therear receiver device 40. In this case, thesubmarine vehicle 2 is guided and mounted both by thefront receiver device 42 and by therear receiver device 40. To this end, therear receiver device 40 compriseswheels 56, fourwheels 56 which guide and mount thesubmarine vehicle 2 can be provided. Thewheels 56 can have a flexible roller material for effective damping. Moreover, thewheels 56 can be adjustable in height. By the arrangement of theguide pulley 52 above the pivot axis S and/or by the arrangement which is displaced relative to the pivot axis S in the direction of thefirst end 16 of therecovery ramp 12, by the tensile force produced by means of therope 50, a lifting moment is produced for thewave compensation ramp 24 and/or for thefree end 34 of thewave compensation ramp 24. - Finally, the
wave compensation ramp 24 comprises a wheel and/orwheels 58 which support thewave compensation ramp 24 and/or thefree end 34 of thewave compensation ramp 24 on therecovery ramp 12 when thewave compensation ramp 24 is lifted onto therecovery ramp 12. -
FIG. 2 shows asnap connection device 60 in a sectional view together with a part of thefront attachment 48 which is engaged in thesnap connection device 60. The coupling means 46 have thesnap connection device 60, thesnap connection device 60 being configured for engaging and retaining thefront attachment 48 and thus for coupling thefront attachment 48 to thefront receiver device 42. - The
front attachment 48 has a spike and/or pin 62 which is guided by means of aguide 64. The coupling means 46 are configured in the region of thesnap connection device 60 in the shape of aguide funnel 66. Thesnap connection device 60 comprisespivotable snap connections - By means of the
rope 50, not shown here, thepin 62 is guided through theguide funnel 66 and theguide 64 onto thesnap connection device 60. Therope 50 can optionally be passed through thepin 62 and through thesnap connection device 60 and/or the top end of theguide 64.Projections pin 62 and/or a peripheral projection which has theportions pin 62, effect a pivoting of thesnap connections snap connections projections snap connections pin 62 and thus thefront attachment 48 are coupled by means of thesnap connection device 60 to thefront receiver device 42. - The
snap connection device 60 can be configured such that thesnap connections projections pin 62 is pushed in the direction of thefront receiver device 42. This can take place, for example for decoupling thesubmarine vehicle 2, by thesubmarine vehicle 2 being moved by means of its drives in the direction of thefront receiver device 42. -
FIG. 3 shows thesystem 1 according to the embodiments ofFIG. 1 with therecovery ramp 12 retrieved, thewave compensation ramp 24 retrieved and thesubmarine vehicle 2 retrieved. The same reference numerals in all the figures denote the same components. Therecovery ramp 12, thewave compensation ramp 24 and thesubmarine vehicle 2 are positioned above themarine bearing assembly 10. Therocker 18 is pivoted such that therecovery ramp 12 is mounted in the region of the second and/orfree end 20 of therecovery ramp 12 on the tiltingroller 14. This arrangement according toFIG. 3 is produced before thesubmarine vehicle 2 is let into the water and/or when thesubmarine vehicle 2 is completely recovered. Moreover, therecovery ramp 12 and thewave compensation ramp 24 can adopt the same position when thesubmarine vehicle 2 carries out its mission and when therope 50 is reeled in, in particular at least as long as therope 50 is fastened to thewinch 54. -
FIG. 4 shows thesystem 1 according to embodiments ofFIG. 1 in an arrangement which substantially equates to the arrangement according toFIG. 1 , but with thesubmarine vehicle 2 being received by thewave compensation ramp 24. Thesubmarine vehicle 2 in this case is mounted by thefront receiver device 42 and therear receiver device 40, amongst other things thenegative shell 44 centering the bow of thesubmarine vehicle 2. - In the illustration according to
FIG. 4 , thefront receiver device 42 has reached its outermost position in the direction of thefirst end 26 of thewave compensation ramp 24. Subsequently, thewave compensation ramp 24 is pulled up onto therecovery ramp 12 by means of thebelt drive 32, optionally assisted by pulling on therope 50. - The exemplary arrangement according to
FIG. 4 is also achieved when thesubmarine vehicle 2 is to be let into the water, namely when theguide carriage 30 has reached its final position in the region of the second orfree end 20 of therecovery ramp 12 or in the region of theaverage waterline 4. -
FIG. 5 shows thesystem 1 ofFIG. 1 in an arrangement in which thesubmarine vehicle 2, as in the arrangement according toFIG. 4 , is received by thewave compensation ramp 24. In contrast to the arrangement according toFIG. 4 , however, thewave compensation ramp 24 with thesubmarine vehicle 2 is also fully received by therecovery ramp 12. Theguide carriage 30 is positioned at thefirst end 16 of therecovery ramp 12 and retains thewave compensation ramp 24 at that point with thesubmarine vehicle 2. In this case, thewave compensation ramp 24 is additionally mounted on the wheel and/or thewheels 58. - The
system 1 is suitable for recovering and launching thesubmarine vehicle 2. Proceeding from the arrangement according toFIG. 3 , the launching takes place via the arrangements according toFIGS. 5 , 4 and 1. The recovery and/or retrieval of the submarine vehicle takes place, proceeding from the arrangement according toFIG. 1 , via the arrangements according toFIGS. 4 , 5 and 3. Alternatively, however, the submarine vehicle can be displaced into the body ofwater 6 from themarine vessel 8 in a different manner, as the launching of thesubmarine vehicle 2 generally involves relatively less risk of damage to thesubmarine vehicle 2 compared to the recovery. For example, thesubmarine vehicle 2 can be let into the body ofwater 6 by means of a crane. -
FIG. 6 shows a block diagram for illustrating amethod 76 for recovering a submarine vehicle and/or thesubmarine vehicle 2 in accordance with the various exemplary embodiments ofFIG. 1 . - The
method 76 always comprises the mounting 78 of therecovery ramp 12 on themarine bearing assembly 10 and/or by means of themarine bearing assembly 10, in particular on themarine vessel 8. Moreover, themethod 76 always comprises the mounting 80 of thewave compensation ramp 24 on therecovery ramp 12 in a pivotable manner about the pivot axis S relative to therecovery ramp 12. Thewave compensation ramp 24 is thus to be regarded as movable during the recovery procedure, whereas although therecovery ramp 12 can be lowered or lifted on board, during the recovery procedure in the narrower sense and/or when the submarine vehicle is coupled thereto, it is to be regarded as stationary. - After the
submarine vehicle 2 has carried out its mission, its energy reserves are generally exhausted so that thesubmarine vehicle 2 does not actively control the recovery procedure, but according to astep 82 launches a buoy which is fixedly connected by means of therope 50 to thefront attachment 48 of thesubmarine vehicle 2. Subsequently, according to astep 84 the buoy is reeled in by means of a ships hook, for example. The buoy is removed from the free end of therope 50. Subsequently according to astep 86, the free end of therope 50 is threaded through thefront receiver device 42 and through therear receiver device 40 and according to a step 88 fastened to thewinch 54. Subsequently, according to astep 90, therecovery ramp 12 which is located above themarine bearing assembly 10 is lifted above the tiltingroller 14 and lowered in the direction of thewaterline 4. Thefree end 20 of therecovery ramp 12 is now located in the region of theaverage waterline 4. Subsequently, according to astep 92, thewave compensation ramp 24 is extended by means of theguide carriage 30. Thewave compensation ramp 24 is now located with itsfree end 34 in the region of theactual waterline 4 and rocks up and down with the waves. - Subsequently, according to a
step 94 thesubmarine vehicle 2 is pulled by means of therope 50. Thewinch 54 at the same time produces a tensile force on therope 50. Whilst thesubmarine vehicle 2 according to step 94 is pulled, according to astep 96 therear receiver device 40 is retained in the region of the water surface and/orwaterline 4, in particular by means of the rear floatingbody 38. Moreover, therope 50 according to astep 98 is guided by means of thefront receiver device 42. Additionally, according to astep 100 therope 50 is deflected by means of theguide pulley 52 from thewave compensation ramp 24 to therecovery ramp 12. Thestep 100 contains astep 102 according to which the lifting of thewave compensation ramp 24 is assisted by means of the tensile force of the rope which is achieved by the arrangement of theguide pulley 52 above the pivot axis S. As a result, a lifting moment is produced on thewave compensation ramp 24. - The
submarine vehicle 2 according to astep 104 is received by means of thewave compensation ramp 24. In this case according to astep 106, thefront receiver device 42 is retained, in particular by means of the front floatingbody 36, in the region of the water surface and/orwaterline 4. In the meantime, according to astep 108 the coupling means 46 are coupled to thefront attachment 48. Thus, thesubmarine vehicle 2 is fixedly docked to thefront receiver device 42. The coupling instep 108 comprises an engagement of thefront attachment 108 by means of thesnap connection 60 according to astep 110. - The centering of the
submarine vehicle 2 by means of thenegative shell 44 according to astep 112 and the guidance of thesubmarine vehicle 2 by means of thefront receiver device 42 according to astep 114 follow hereinafter as further components of the receiving procedure according to step 104, thesubmarine vehicle 2, in particular, also being mounted by means of thefront receiver device 42. Moreover, thestep 104 comprises the guidance and mounting of thesubmarine vehicle 2 by means of therear receiver device 40, in particular by means of thewheels 56 of therear receiver device 40 according to astep 116. Finally, a linear displacement of thefront receiver device 42 on thewave compensation ramp 24 according to astep 118 forms part of a receiving procedure for thesubmarine vehicle 2 by means of thewave compensation ramp 24 according to thestep 104. The displacement takes place by means of the tensile force exerted by thewinch 54 via therope 50. - If the
submarine vehicle 2 is pulled up to the final designated position onto thewave compensation ramp 24, after thestep 94, according to astep 120 thesubmarine vehicle 2 is retrieved by means of therecovery ramp 12 on board themarine vessel 8 and/or to a position above themarine bearing assembly 10. In particular, according to astep 122 thewave compensation ramp 24 together with the receivedsubmarine vehicle 2 are retrieved and/or moved on board themarine vessel 8 and/or above themarine bearing assembly 10. To this end, according to astep 124 theguide carriage 30 is displaced, in particular by means of thebelt drive 32, and thus thewave compensation ramp 24 is lifted according to astep 126. Subsequently, thewave compensation ramp 24 bears fully against therecovery ramp 12. Then, according to astep 128, therecovery ramp 12 is lifted by means of therocker 18 via the tiltingroller 14, in particular by means of thehydraulic cylinder 22. Thus, thesubmarine vehicle 2 is finally located above thewave compensation ramp 24, above therecovery ramp 12 and above themarine bearing assembly 10 and/or recovered on board themarine vessel 8. - The
system 1 can also be used for launching thesubmarine vehicle 2. The method steps required therefor are in part similar to the method steps for recovering thesubmarine vehicle 2 in reverse sequence. In this case, however, therope 50 can be not fastened to thewinch 54 but is located on thesubmarine vehicle 2 together with the buoy fastened to therope 50. In particular, the launching of thesubmarine vehicle 2 takes place by therecovery ramp 12 being lowered by means of therocker 18 via the tiltingroller 14 together with thewave compensation ramp 24 located thereon and thesubmarine vehicle 2 located thereon. Subsequently, thesubmarine vehicle 2 slides over therecovery ramp 12 into the water. - Alternatively, the
guide carriage 30 is moved down therecovery ramp 12 and thus the wave compensation ramp is lowered. Finally, by means of the coupling means 46, the coupling of thesubmarine vehicle 2 and/or thefront attachment 48 to thefront receiver device 42 is released. In this case, thefront receiver device 42 is either secured by means of a retaining means in the region of thefirst end 26 of thewave compensation ramp 24 or has previously moved to the second and/orfree end 34 of the wave compensation ramp. -
FIG. 7 shows anegative shell 44′ in a sectional view from above with twoguide strips guide strip 130 upwards and theguide strip 132 downwards, according to this alternative example,FIG. 7 being a sectional view of a side view. Moreover, as an alternative to the exemplary embodiment shown, further guide strips can be provided, the guide strips being spread apart in several directions and together forming a three-dimensional funnel. - For spreading apart the guide strips 130 and 132, the
negative shell 44′ and/or thefront receiver device 42, not shown here, with thenegative shell 44′ are displaced from thefirst end 26 of thewave compensation ramp 24, not shown here, to the second and/orfree end 34 of thewave compensation ramp 24, the guide strips 130 and 132 being spread apart and finally as shown inFIG. 7 being spread apart when thenegative shell 44′ is arranged in the region of therear receiver device 40 connected fixedly to thewave compensation ramp 24. Thesubmarine vehicle 2, the bow thereof being shown inFIG. 7 , can move in the direction of thenegative shell 44′ and/or be pulled by means of therope 50, not shown here, thesubmarine vehicle 2 being guided securely to thenegative shell 44′ by means of the guide strips 130 and 132, even in the case of potential lateral currents, and being able to be coupled there. In particular, the guide strips 130 and 132 prevent thesubmarine vehicle 2 from striking against therear receiver device 40. The guide strips 130 and 132 comprise floating bodies and are mounted flexibly and/or movably such that the guide strips 130 and 132, which are spread apart to the side, are also arranged locally in the region of the water surface of the body ofwater 6. Thesubmarine vehicle 2 and the local portions of the guide strips 130 and 132, towards which thesubmarine vehicle 2 moves, are thus located approximately at the same height so that thesubmarine vehicle 2 is not able to reach a position above or below a guide strip, in which it might run the risk of being struck vertically by therespective guide strip 130 and/or 132. -
FIG. 8 shows thenegative shell 44′ ofFIG. 7 with the mountedsubmarine vehicle 2, in accordance with various embodiments. Thesubmarine vehicle 2 is retained by the guide strips 130 and 132 in position. Thenegative shell 44′ and/or thefront receiver device 42 with thenegative shell 44′ are located in this case in the region of thefirst end 26 of thewave compensation ramp 24, not shown here, so that thesubmarine vehicle 2 is mounted on thewave compensation ramp 24. - Proceeding from the view according to
FIG. 7 , the view according toFIG. 8 is achieved by thesubmarine vehicle 2 being pulled onto thewave compensation ramp 24 after being coupled to thefront receiver device 42 and/or to thenegative shell 44′, thenegative shell 44′ being displaced from thefree end 34 of thewave compensation ramp 24 in the direction of thefirst end 26 of thewave compensation ramp 24 and/or thenegative shell 44′ being retracted. In this case, the guide strips 130 and 132 slide partially through therear receiver device 40, so that the guide strips 130 and 132 are forced together by means of therear receiver device 40 and/or forced in the direction of thesubmarine vehicle 2. - The invention prevents a hard impact of the
submarine vehicle 2 against therecovery ramp 12, both when launching and when recovering thesubmarine vehicle 2, even in moderate and/or heavy seas.Submarine vehicles 2 can be launched and recovered by means of thesystem 1 according to the invention and/or by means of themethod 76 according to the invention with reduced risk of damage to thesubmarine vehicle 2, even in moderate and heavy seas. - All features cited in the above description and in the claims are able to be used individually and in any combination. The disclosure of the invention is therefore not limited to the described and/or claimed combinations of features. On the contrary, all combinations of features should be considered as being disclosed.
