Description
System for launching and recovering marine and submarine devices assisted by tiltable protective components The present invention is in the maritime field and relates to a system for launching and recovering marine or submarine devices (Launch And Recovery System (L.A.R.S.)) capable on the one hand of raising the device from the water as far as a towing system on board a support vessel and on the other hand of lowering the device from the support vessel onto the sea. It notably applies to launching towed or autonomous submarine devices, the latter then being provided with a temporary connection during the launch and recovery phases.
The operations of launching and recovering a marine or submarine device from or to a support vessel also responsible for the transportation of said device generally include a critical phase, especially in a choppy sea.
That phase consists in the passage from the totally out of the water state in which the device is fastened to the handling means employed to the totally submerged state in which the device no longer has any connection with the latter means, and vice versa. In fact, it is during these critical phases that the swell is the most dangerous for the integrity of the device, the latter being agitated by the swell when it is close either to the structure of the vesse!
or to that of the lifting and handling means, with the attendant risk of striking them.
This is the case in particular for a marine or submarine device in the launch or recovery phase when the device is partly in the water: its movements are not yet (or no longer) completely controlled by the lifting and handling means.
Accordingly, where autonomous devices, not towed by the vessel, are concerned, one known solution consists in providing mooring means on the hull of the device, for example securing means, said securing means being such that the device can be lifted whilst remaining in a horizontal position. Launching and recovery can then be carried out using a winch mounted on a mobile gantry placed at the stem n of the vessel, for example, or a crane, the gantry or the crane making it possible to position the

This is the case in particular for a marine or submarine device in the launch or recovery phase when the device is partly in the water: its movements are not yet (or no longer) completely controlled by the lifting and handling means.
Accordingly, where autonomous devices, not towed by the vessel, are concerned, one known solution consists in providing mooring means on the hull of the device, for example securing means, said securing means being such that the device can be lifted whilst remaining in a horizontal position. Launching and recovery can then be carried out using a winch mounted on a mobile gantry placed at the stem n of the vessel, for example, or a crane, the gantry or the crane making it possible to position the
2 lifting winch over the recovery area. Thereafter launching and raising are effected vertically, which limits the possibilities of collision with the vessel during raising or lowering. Alternatively, the device can be lifted by placing it in a cradle type device itself including appropriate securing points.
This type of solution is applicable, notably autonomously, to devices towed from the center but is not easily applicable to devices towed from the front, however, in that, for obvious reasons of efficacy, the aim is to tow and to handle the device using a single cable. Handling by means such as those described above using a single cable proves delicate because it leads to the device passing from the vertical position to the horizontal position during launch and conversely during recovery. This handling moreover necessitates complementary operations the object of which is, after the device is lifted and positioned above the deck of the vessel, to deposit the device flat on the deck of the vessel or more generally in a storage area. These operations generally necessitate the intervention of human operatives, which intervention is rendered more delicate and more dangerous in a heavy sea.
In the case of devices towed from the front, the solution that is generally preferred consists in using a handling cable temporarily attached above the center of gravity of the device.
A solution that is also used provides handling based on the placement of means including an inclined ramp on which the device slides onto the surface of the water or to leave it and return to the vessel. The ramp is generally configured to guide the device along a rectilinear trajectory, which prevents the device from being able to move laterally. However, a ramp of this kind is not generally suitable for use in a heavy sea: lateral movements of the device can then damage it.
Using such means advantageously makes it possible to launch and to deploy the device behind the vessel by allowing the towing cable to play out and, conversely, to recover the device on board the vessel by winding in the cable, for example onto the drum of a winch, ln this way the device towed by the vessel can be launched and recovered when the vessel is moving so that

3 the device is naturally positioned on the axis of forward movement of the latter.
Various solutions have been developed to alleviate these problems of coming into contact, generally suited to a given type of device.
These known solutions generally consists in reinforcing the structure of the device, principally the nose, sa that the latter resists impacts following entry into contact with the end of the ramp. It also consists in using means for minimizing these impacts, in particular configuring the ramp sa that its end is situated below the surface of the water sa that the device floating on the surface cornes into contact with the inclined surface of the ramp and not its end. Solutions of this kind nevertheless prove inadequate in a heavy sea because the slamming effect of the waves is then accentuated by the movement of the vessel.
Other solutions have been developed (see for example EP
20110793422 and US 8430049B1) in which the vessel incorporates a tiltable articulated ramp. The inclination of the ramp makes it possible to control the submerged part of the ramp. Once the ramp is submerged, the device is towed over the abutment that separates the ramp from the surface of the water. Moreover, in a heavy sea the ramp may corne out of the water.
The foregoing solution is effective but cannot be fitted to all vessels. In fact, many vessels cannot support the weight necessary for the installation of the equipment linked to the operation of a tiltable articulated ramp. The problem solved by the present invention is to cause the marine or submarine device to pass over a step situated between the end of the ramp and the water, notably when a small vessel is used, for example less than 50 meters long and preferably less than 20 meters long, incapable of sup-porting the installation of equipment that is too heavy, such as a tiltable articulated ramp as described in the prior art.

In the remainder of the text the terms front, rear, in front of and behind are defined relative ta the longitudinal axis of the vessel 6 oriented from the stem n toward the bow of the vessel 6.

That device comprises two elements: the carnage 2 and the protective component 5, itself comprising two parts fastened together, the protective part 4 and the arm 3. In the figure 1 example, the two protective components 5 are installed one on each side of the carnage 2 and are fastened ta each other. They can pivot about the carnage about the axis y shown. That axis y is parallel ta the surface of the water 25 when the device is secured ta a support vessel as described hereinafter in order ta be able ta lift or ta deposit the marine or submarine device 7 carried by the protective parts 4, preferably having a curved part ta prevent forward or rearward movement of the marine or submarine device 7 during the maneuver. In one particular embodiment the carnage 2 includes a part 26 that has the function of a fairlead.
Figure 2 presents a diagrammatic profile view of one embodiment of a protective part 4. The shape of this embodiment is in part curved. One of its functions is ta carry the marine or submarine device 7 and ta limit or ta prevent movements toward the front of the device 7 of swerving, heaving, lurching, rolling and yawing caused by externat stresses. In one particular
8 embodiment of the invention, the rear of the protective part 4 features a hollowed out part. This configuration can be particularly useful in the case of contact between the protective part 4 and a wing 12 of the marine or submarine device 7.
The rear of the wing 22, termed the trailing edge, is thinner and mechanically weaker than the front part 23: in this embodiment, contact can occur only on the surface of the mechanically strongest part of the wing 12.
Figure 3 presents a profile view of one embodiment of the whole of the L.A.R.S. during a phase of launching or recovering a marine or submarine device 7. In this embodiment the position of the protective component 5 is determined by three factors:
- the pivot connection with the carnage 2, described above, - the difference between the force of gravity and the Archimedean upthrust exerted on the protective component 5: in this particular embodiment the protective component 5 is termed of the heavy type because it does net float, and - the contact with the wing 12 of the marine or submarine device 7 that bears on the protective component 5.
In this configuration, the pivot connection connecting one of the protective components 5 and the carnage 2 is qualified as freely rotatable.
Although the rotation can be constrained by one of the above three factors, this qualification is aise made to distinguish this embodiment from a particular embodiment in which the position of a protective component 5 can be determined primarily by a driving torque applied by first driving means te the protective component 5 via the pivot connection connected te the carnage 2.
In one particular embodiment of the invention, a floating protective component can for example be coupled te first driving means te control the submersion of the floating protective component.
In figure 3 the carnage 2 is situated at the bottom of the ramp 11, in a low or retracted position, te which ramp it is connected by a sliding connection. In the phase of launching or raising the marine or submarine
The rear of the wing 22, termed the trailing edge, is thinner and mechanically weaker than the front part 23: in this embodiment, contact can occur only on the surface of the mechanically strongest part of the wing 12.
Figure 3 presents a profile view of one embodiment of the whole of the L.A.R.S. during a phase of launching or recovering a marine or submarine device 7. In this embodiment the position of the protective component 5 is determined by three factors:
- the pivot connection with the carnage 2, described above, - the difference between the force of gravity and the Archimedean upthrust exerted on the protective component 5: in this particular embodiment the protective component 5 is termed of the heavy type because it does net float, and - the contact with the wing 12 of the marine or submarine device 7 that bears on the protective component 5.
In this configuration, the pivot connection connecting one of the protective components 5 and the carnage 2 is qualified as freely rotatable.
Although the rotation can be constrained by one of the above three factors, this qualification is aise made to distinguish this embodiment from a particular embodiment in which the position of a protective component 5 can be determined primarily by a driving torque applied by first driving means te the protective component 5 via the pivot connection connected te the carnage 2.
In one particular embodiment of the invention, a floating protective component can for example be coupled te first driving means te control the submersion of the floating protective component.
In figure 3 the carnage 2 is situated at the bottom of the ramp 11, in a low or retracted position, te which ramp it is connected by a sliding connection. In the phase of launching or raising the marine or submarine
9 device 7 the front end of the device 7 is fastened to the traction cable 16.
This traction cable 16 is inserted in the fairlead 26 of the carnage 2 and remains in close contact therewith, which has the advantageous effect of maintaining the axis of the device 7 on the axis of the ramp 11 as it moves along the latter.
This remaining in contact occurs naturally because the carnage 2 is a heavy component the weight of which, in the absence of the marine or submarine device 7, tends to cause it to descend along the ramp 11. During a launch, the carnage 2 therefore accompanies the movement of the marine or submarine device 7. In one particular embodiment of the invention, the carnage 2 includes second driving means that enable it to force the descent along the ramp 11 in order to remain in contact with the marine or submarine device 7 during its recovery or launch.
The marine or submarine device 7 is raised or lowered by traction means 14 consisting of the traction cable 16 fastened to the marine or submarine device 7 and a winch 15 fastened to the support vessel 6 that enables the cable 16 to be wound in during a recovery phase or the cable 16 to be paid out during a launch phase thanks to third driving means 20 able to impose a second driving torque on the winch 15. In one particular embodiment, the marine or submarine device 7 can be an autonomous marine or submarine device. In this case, the marine or submarine device 7 is provided with a temporary connection during the launch and recovery phases: the connection between the traction cable 16 and the device 7 is termed indirect. During the use of an autonomous marine or submarine device this embodiment can be combined with or replaced by an embodiment in which at least one of the protective components 5 has a device for attaching it to the device 7 enabling the device 7 and the protective component or components to be connected when they come into contact at the commencement of recovery of the device 7, for example.
Figure 3 also presents a raising component 18 situated at the edge of the ramp 11. Its function is described in detail in the description of figure 4.
Figure 3 illustrates an example of the protective component 5 coming into contact with the raising component 18 during the recovery or launch phase.
Figure 4 presents a diagrammatic perspective view of the entire system when the marine or submarine device 7 has been raised completely 5 onto the ramp 11. According to an embodiment presented in this figure, the marine or submarine device 7 has been recovered using the device described in figure 1 in which the two protective components 5 are installed one on each side of the carnage 2 and are fastened to each other. This feature enables the marine or submarine device 7 to pass over the step
This traction cable 16 is inserted in the fairlead 26 of the carnage 2 and remains in close contact therewith, which has the advantageous effect of maintaining the axis of the device 7 on the axis of the ramp 11 as it moves along the latter.
This remaining in contact occurs naturally because the carnage 2 is a heavy component the weight of which, in the absence of the marine or submarine device 7, tends to cause it to descend along the ramp 11.

In one particular embodiment of the invention, the carnage 2 includes second driving means that enable it to force the descent along the ramp 11 in order to remain in contact with the marine or submarine device 7 during its recovery or launch.
The marine or submarine device 7 is raised or lowered by traction means 14 consisting of the traction cable 16 fastened to the marine or submarine device 7 and a winch 15 fastened to the support vessel 6 that enables the cable 16 to be wound in during a recovery phase or the cable 16 to be paid out during a launch phase thanks to third driving means 20 able to impose a second driving torque on the winch 15. In one particular embodiment, the marine or submarine device 7 can be an autonomous marine or submarine device. In this case, the marine or submarine device 7 is provided with a temporary connection during the launch and recovery phases: the connection between the traction cable 16 and the device 7 is termed indirect. During the use of an autonomous marine or submarine device this embodiment can be combined with or replaced by an embodiment in which at least one of the protective components 5 has a device for attaching it to the device 7 enabling the device 7 and the protective component or components to be connected when they come into contact at the commencement of recovery of the device 7, for example.
Figure 3 also presents a raising component 18 situated at the edge of the ramp 11. Its function is described in detail in the description of figure 4.
Figure 3 illustrates an example of the protective component 5 coming into contact with the raising component 18 during the recovery or launch phase.
Figure 4 presents a diagrammatic perspective view of the entire system when the marine or submarine device 7 has been raised completely 5 onto the ramp 11. According to an embodiment presented in this figure, the marine or submarine device 7 has been recovered using the device described in figure 1 in which the two protective components 5 are installed one on each side of the carnage 2 and are fastened to each other. This feature enables the marine or submarine device 7 to pass over the step
10 between the end of the ramp 11 and the surface of the water 25 without the nose or the front of the marine or submarine device 7 being in contact with the ramp 11. This method makes it possible to avoid impacts capable of damaging fragile onboard components such as components or sensors, in particular of a sonar.
Figure 4 makes it possible to illustrate the sliding zone 17 situated along the ramp 11. It remains in contact with the protective component or components 5 when the carnage 2 slides along the ramp 11. According to one embodiment considered, the protective part 4 comprises a roller 10 mounted at one of its ends and pivoting about an axis parallel to the surface of the water 25, as illustrated in figure 3. This roller 10 enables the protective part 4 not to rub on the sliding zone 17 when the marine or submarine device 7 moves on the ramp 11. According to another embodiment of the invention, the protective part 4 comprises one or more rollers 10 mounted on a part of said protective part 4 able to cooperate with said sliding zone 17 and/or a raising component 18 pivoting about a second axis parallel to the surface of the water 25 when the system is secured to the vessel 6. These rollers make it possible to prevent rubbing between the protective components 5 and the sliding zone 17 and/or one or more raising components 18. They are for example arranged under the protective part or parts 4 relative to the frame of reference of the vessel.

These rollers make it possible to prevent rubbing between the protective components 5 and the sliding zone 17 and/or one or more raising components 18. They are for example arranged under the protective part or parts 4 relative to the frame of reference of the vessel.
11 According ta the embodiment considered, the sliding zone 17 also enables the raising component 18, which is fastened ta it, ta be supported with the object of causing the protective component 5 ta move through contact.
Figure 4 moreover illustrates protection and sliding means 30 mounted on the ramp 11 and adapted ta favor the movement of the device 7 along the ramp 11 because of the traction exerted by the traction cable 16 and gravity. Said means are for example ratiers disposed laterally on the bottom of the ramp 11 and on which the device 7 rolls.
Figure 5 is a sequence of diagrammatic profile views of the entire L.A.R.S. showing a complete phase of recovery of the marine or submarine device 7. One of the main technical problems can be illustrated by figure 5.F.
That figure illustrates the vertical step of height h present between the surface of the water 25 and the end of the inclined ramp 11. That vertical watt represents a source of impacts or shocks with the wall of the marine or submarine device 7 during launch and recovery thereof, notably when the front of the marine or submarine device 7 passes between the surface of the water 25 and the bottom of the ramp.
The effect of the present invention is ta enable launching and recovery of the marine or submarine device 7 avoiding all contact between the step described above and the front of the marine or submarine device 7.
The recovery sequence is described on the basis of figure 5.A. That figure illustrates an approach phase of the marine or submarine device 7. The latter is submerged and fastened ta the traction cable 16. It may however be noted that another embodiment may include a marine or submarine device 7 navigating on the surface during this recovery phase. The carnage 2 is placed in a retracted position, i.e. at the bottom end of the ramp 11, by gravity or by the second driving means. The protective components 5 are in the low position, i.e. pivoted downward, sa as ta be submerged ta receive the marine or submarine device 7. In the figure 5.A example, the principal axis of

The protective components 5 are in the low position, i.e. pivoted downward, sa as ta be submerged ta receive the marine or submarine device 7. In the figure 5.A example, the principal axis of
12 inertia of the protective components makes an angle with the surface of the water 25 between 800 and 90 inclusive.
Figure 5.B illustrates the phase of the marine or submarine device 7 coming alongside. The traction cable 16 is wound in by the winch 15. In this embodiment the marine or submarine device 7 has wings 12. The traction by the cable draws the wings 12 into abutment with the protective components 5.
Figure 5.0 illustrates the phase of the front part of the marine or submarine device 7 mounting the step. The traction cable 16 continues to be wound in by the winch 15. The protective components 5 are constrained by the wings 12 of the marine or submarine device 7, by the sliding zone 17 and by the raising components 18: the protective components 5 then pivot about the carnage 2, their rotation being forced by the sliding zone 17 and/or a raising component 18. This rotation of the protective components 5 raises the front of the marine or submarine device 7 ta the level of the ramp. The front of the marine or submarine device 7 does not at this time touch any component of the L.A.R.S., which makes it possible ta protect the sensors from potentially destructive shocks.
Figures 5.D and 5.E illustrate the continued raising of the marine or submarine device 7 on the ramp 11. In figure 5.D, the traction cable 16 continues ta be wound in by the winch 15. The protective components 5 continue ta pivot about the carnage 2 as the carnage 2 slides forward along the ramp 11. The protective components 5 slide, or in one particular embodiment roll, on the raising component 18, enabling the front of the marine or submarine device 7 ta be raised further. The body of the marine or submarine device 7, stronger than its front, bears on protection and sliding means 30 of the ramp, in this instance rollers.
In figure 5.E, the traction cable 16 continues ta be wound in by the winch 15. VVhen traction is applied, the marine or submarine device bears on the protection and sliding means 30 of the ramp 11 until it rests on the ramp 11. The contact between the protective components 5 and the raising
Figure 5.B illustrates the phase of the marine or submarine device 7 coming alongside. The traction cable 16 is wound in by the winch 15. In this embodiment the marine or submarine device 7 has wings 12. The traction by the cable draws the wings 12 into abutment with the protective components 5.

Figures 5.D and 5.E illustrate the continued raising of the marine or submarine device 7 on the ramp 11. In figure 5.D, the traction cable 16 continues ta be wound in by the winch 15. The protective components 5 continue ta pivot about the carnage 2 as the carnage 2 slides forward along the ramp 11. The protective components 5 slide, or in one particular embodiment roll, on the raising component 18, enabling the front of the marine or submarine device 7 ta be raised further. The body of the marine or submarine device 7, stronger than its front, bears on protection and sliding means 30 of the ramp, in this instance rollers.
In figure 5.E, the traction cable 16 continues ta be wound in by the winch 15. VVhen traction is applied, the marine or submarine device bears on the protection and sliding means 30 of the ramp 11 until it rests on the ramp 11. The contact between the protective components 5 and the raising
13 components 18 ceases and the protective components 5 slide or roll on the sliding zones 17.
Figure 5.F illustrates the marine or submarine device 7 raised to the end of the ramp 11. The protective components 5 are no longer in their raised position. The front of the marine or submarine device 7 then rests on the ramp 11 via its body. The protective components 5 remain in contact with the wings 12 and therefore notably limit or prevent rolling of the marine or submarine device 7.
The attitude of the marine or submarine device 7 varies during launch or recovery as a function of its initial attitude and loads imposed by the system. In embodiments of the invention, the normal maximum attitude variation of the marine or submarine device 7 may be between 0 and 900 inclusive. The system is able to modify the attitude of said marine or submarine device during launch or recovery of said marine or submarine device.
In one particular embodiment of the invention, the marine or submarine device 7 does not comprise either wings 12 or lateral protuberances. The recovery and launch phases are analogous to those illustrated in figure 5: in this embodiment, the protective part or parts 4 are directly in contact with the hull of the marine or submarine device 7.
