- FIG. 21 shows, in a view similar to that of Figures 19 and 20, the cooperation between the handle and the lifting support.
- Figure 1 shows the context of application of the invention, and corresponds to the state of the art. More particularly, Figure 1 shows a part of a carrier vessel 1, which includes a deck 2, for example a rear deck.
- the rear deck 2 is intended to receive, for example on cradles 3, a marine vehicle 4, which is a surface marine vehicle.
- the marine vehicle 4 shown here is a semi-rigid hull boat, which may form part of the drome of the carrier vessel 1.
- the carrier vessel has a davit 5, the end of which can be positioned cantilevered from the hull 6 of the carrier vessel.
- the lifting cable can in particular be unwound from the carrier vessel 1 to lower the vehicle. sailor 4 or rolled up in the carrier vessel 1 in order to lift the marine vehicle 4, for example using a pulley winch.
- the lifting cable 7 is connected for this purpose to a lifting point of the marine vehicle, which is formed by an element adapted to support the weight of the marine vehicle and its
- one or more drop arms control the orientation of the marine vehicle suspended from the davit.
- the lifting point can be formed on a set of straps or ropes linked at several points of the marine vehicle, and the invention which is described below is applicable to such a configuration.
- the lifting point is considered to be a single point, forming part of the marine vehicle 4.
- the system presented is first of all incompatible with the recovery of a remotely operated or autonomous marine vehicle 4, unmanned. In addition, it does not allow the recovery of the marine vehicle 4 when the sea is rough.
- the lifting cable 7 is difficult to recover because of the movements of the surface marine vehicle on rough seas. Even if the crew of the marine vehicle 4 manages to grab the lifting cable 7, its hooking up at the level of the lifting point 8 is complex, even dangerous.
- the swell causes rapid variations in the level (height) of the surface marine vehicle 4 with respect to the height of the deck 2 of the carrier vessel 1.
- the invention proposes a system, based on a conventional davit device such as that of Figure 1, and adaptable to a pre-existing device, allowing the recovery of a surface marine vehicle in rough seas.
- the invention is described below on the basis of a lifting device comprising a davit itself.
- the invention can more generally implement a lifting means "of the davit type", that is to say a davit itself or an equivalent lifting device, cantilevered from the hull of a carrier vessel. , for example a crane similar in configuration to a davit.
- FIG. 2 illustrates the main elements of a system according to an embodiment of the invention, including an example of constitution and the use of which are explained with reference to the following figures.
- the system of FIG. 2 is thus based on that of the prior art illustrated in FIG. 1.
- a lifting device is fitted to a carrier vessel 1.
- the lifting device comprises a davit 5, which is equipped with a lifting cable 7.
- the davit 5 is here installed on the deck 2 of the carrier vessel 1.
- the lifting device comprises a pole 9 extending laterally from the hull 2 of the carrier vessel 1, which can also be denoted by the term " gallows ”.
- the pole 9 carries, for example at its end, a cable called the guide cable 10.
- the guide cable 10 is thus suspended in a vacuum by the pole 9.
- An anchor 11 is fixed to the free end of the guide cable 10.
- the boom 9 is positioned above the waterline of the carrier vessel 1 and preferably above the level of the deck 2 and the davit 5.
- the length of the guide cable 10 allows the anchor 11 to be submerged. In other words, when the anchor is suspended freely by the guide cable 11, it is located below the waterline of the carrier vessel 1.
- the anchor is suspended widely below the waterline of the carrier vessel 1. , in order to remain permanently submerged despite the swell.
- the anchor can be suspended between two and four meters below the waterline of the carrier vessel 1.
- the length of the guide cable 10 can be fixed or adaptable.
- a guide cable 10 of adaptable length for example using a winch on board the carrier vessel 1, makes it possible for example to adapt the length of said guide cable 10 to the sea swell level.
- the anchor 11 may consist of a solid element, for example metallic.
- the anchor 11 may have hydrodynamic planes which orient the anchor in a predefined position when the carrier vessel 1 advances.
- the free end of the lifting cable 7 is removably attached to the anchor 11. Further, an end portion of said lifting cable 7 is removably attached to the guide cable 10, so that, 'anchor 11 at a given point of the guide cable, located between the anchor 11 and the pole 9, the lifting cable 7 follows the guide cable 10. On this portion, the lifting cable 7 and the guide cable 10 thus form a single elongated set.
- the lifting device further comprises a towing cable 12.
- the towing cable 12 equivalent to a false arm used in known devices, is linked to the carrier vessel 1 at a point on the hull 6 located in front of the davit 5. and in front of the pole 9.
- the towing cable 12 by its orientation, allows, when it is linked to a surface marine vehicle which must be recovered by the carrier vessel 1, to tow the marine vehicle and to keep it longitudinally in position relative to the carrier vessel 1.
- the system of FIG. 2 further comprises a reception device carried by the marine vehicle 4.
- the reception device comprises a front module 13, installed at the front of the surface marine vehicle 4.
- the front module 13, the constitution of which is detailed below, can be called a “rostrum”, because it extends partly cantilevered from the bow of the marine vehicle 4.
- FIG. 3 illustrates, according to a block diagram seen from the side, a lifting device implemented in one embodiment of the invention.
- the components of the lifting device are positioned in Figure 3 substantially according to the positioning they have when the lifting device is installed on a carrier vessel.
- the lifting device comprises:
- the lifting cable 7 the length of which varies under the effect of the winch of the davit 5, the lifting cable being provided at its free end with a link interface 4;
- the towing cable 12 the length of which can be changed according to the recovery phases of the marine vehicle 4, has a free end fixed to the anchor 11.
- variable length of a cable it is understood that the free part of the cable is of variable length, typically the length of the lifting cable 7 between the davit 5 and its free end, the length of the guide cable between the pole 9 and the anchor 11, the length of the traction cable 12 between the hull 6 of the carrier vessel and the anchor 11.
- the lifting device of FIG. 3 is shown in a configuration ready for the recovery of a marine vehicle.
- the connection interface 14 takes the form of a hook, and is fixed to the anchor 11.
- the end portion of the lifting cable 7 is fixed to the corresponding end portion of the guide cable 10, by connecting means 15.
- the connecting means 15 nevertheless allow the release of the connection between the lifting cable 7 and the guide cable 10, for example under the effect of sufficient force.
- a float or a buoy 16 can equip the guide cable 10.
- FIG. 4 represents a marine vehicle 4, namely a boat with a semi-rigid hull, which constitutes a preferred application of the invention.
- the marine vehicle 4 is equipped with a reception device, implemented for the recovery of the marine vehicle 4 by the carrier vessel 1.
- the reception device comprises a front module 13 and a lifting support installed at a point lifting device 8 of the marine vehicle 4.
- the front module 13 is installed at the bow of the marine vehicle 4.
- FIG. 5 thus represents schematically, seen from above, a surface marine vehicle 4, equipped with a reception device implemented in the invention, and in particular a front module 13.
- the marine vehicle 4 must be recovered at using a davit lifting device 5, in order to be hoisted by its lifting point 8 on the deck of a carrier vessel.
- the lifting device corresponds more precisely to the lifting device shown in Figure 3.
- the front module 13 comprises two bars 17 which can pivot vis-à-vis the rest. of the front module 13, a retracted position shown in FIG. 4, in which they take up little space and extend slightly outside the marine vehicle 4 during its navigation, and the deployed position shown in FIG. 6.
- the bars 17 In the retracted position, also called “passive”, the bars 17 can substantially match the shape of the hull (rigid or inflatable) of the marine vehicle 4. In the deployed position, also called “active”, the bars 17 are oriented
- the bars 17 extend cantilevered at the front of the marine vehicle 4 substantially horizontally (parallel to the surface of the water), and form an angle between them to allow recovery and guidance towards the front module 13 of any cable or substantially vertical element entering between them.
- the front module can be used according to various variant embodiments of the invention, in order to form a guide converging, in particular with fixed bars, or movable in planes other than the horizontal plane.
- the bars 17 can be curved (for example to match the shape of the front hull of the marine vehicle).
- the means allowing the reception of a cable or rope at the level of the bow of the marine vehicle can have other forms than two bars, it can be in one piece or on the contrary be formed of several elements which can unfold to form a guide. .
- the movement of the bars 17, or any other means allowing reception of a cable at the front of the marine vehicle can be automatic (motorized) or manual.
- FIG. 7 represents the front module 13, with its bars 17 deployed, during the approach of the guide cable 10.
- the guide cable 10 is illustrated in three successive positions, referenced a, b, and c.
- the guide cable is linked to the lifting cable 7.
- position a the guide bars 17 abut, due to the advance of the machine. marine 4, against the guide cable 10 and the lifting cable 7.
- the bars 17 guide the guide cable 10 and the lifting cable 7 towards a trigger 18, on which the guide cable 10 and the lifting cable 7 press so as to actuate it in rotation (position b in FIG. 7).
- the guide cable 10 and the lifting cable 7 then enter an opening 19 formed in the front module 13. Once the trigger 18 escapes the guide cable 10 and the lifting cable 7, it closes again so as to prevent the guide cable 10 and the lifting cable 7 to come out of the opening 19.
- the guide cable 10 and the lifting cable 7 can nevertheless freely translate vertically in the opening 19. This position corresponds to the position c illustrated in Figure 7, and also corresponds to the step illustrated in Figure 8, in a side view similar to the view of Figure 3.
- the marine vehicle 4 is linked by its front module 13 to the guide cable 10 and concomitantly with the lifting cable 7, which can nevertheless be translated in the front module 13, under the effect of a movement of the marine vehicle relative to the carrying boat, this movement possibly corresponding to a movement in the horizontal plane ( advancement or retreat of the marine vehicle, lateral movement l) or vertically (movement caused by waves, swell).
- the marine vehicle 4 has moved back vis-à-vis the pole 9, which has the effect of raising the guide cable 10 in the front module 13.
- the anchor 11 is thus out of the water, and begins to approach the underside of the front module 13.
- the recoil of the marine vehicle can be achieved by slowing down, at a speed lower than that of the carrier boat, for example.
- the system illustrated here includes a guide cable of fixed length.
- the guide cable may be of variable length, for example adjustable using a winch, to cause the guide cable to rise in the opening 19 of the front module 13.
- the anchor 11 has come into contact with the front module 13.
- the anchor 11 is nested in the front module 13. More precisely, an arm 20 of the anchor 11 s' is housed in a corresponding receiving housing of the front module 13.
- the arm 20 of the anchor is a part of the anchor preferably oriented substantially vertically, so that it fits into the housing of the front module 13 through an opening provided under said front module 13. Once in the receiving housing, the arm 20 and therefore the anchor 11 are immobilized vis-à-vis the front module 13.
- connection interface 14 of the lifting cable which here has the shape of a hook
- the part of the anchor 11 to which the connecting interface 14 of the lifting cable is linked which here has the shape of a hook, is introduced into the opening 19 of the front module 13. This positions the hook opposite a handle 21, visible in FIG. 7.
- the connection interface is then engaged on said handle 21, and hooks to the latter.
- any other connection interface configuration can be envisaged, as long as said connection interface is configured so as to bind to the handle 21 when fixing the anchor 11 to the front module 13.
- the winch of the davit 5 is actuated, which reduces the length of the lifting cable 7.
- the shortening of the lifting cable 7 begins to cause its separation from the guide cable 10, as shown in figure 10 where the connecting means located at the above the buoy 16 has given way to free the hoisting cable 7.
- the connecting means 15 gradually release the lifting cable 7 until it is completely separated from the guide cable 10.
- the handle 21 is also linked by a cable to a winch located near the lifting point 8 of the marine vehicle 4.
- the towing cable 12 ensures the longitudinal retention of the marine vehicle vis-à-vis the carrier boat.
- the guide cable 10 essentially ensures its lateral support, at its bow.
- the marine vehicle 4 can then be lifted, hoisted out of the water by the lifting cable 7. More precisely, the link interface14 (for example in the form of a hook) of the cable lifting device is engaged with handle 21 which is attached to the lifting support.
- This step is represented in FIG. 12.
- FIG. 13 represents this same step, in a three-dimensional view similar to that of FIGS. 1 and 2, in which the carrier vessel 1, its deck 2, and the davit 5 in particular are clearly visible.
- FIGS 14 to 18 illustrate in detailed principle views the sequence that takes place at the front module 13 during the recovery of the marine vehicle.
- Figure 14 shows the anchor 11, which has an arm 20. It has a vertical extension 22 to which is linked the guide cable 10.
- the link interface 4 located at the end of the lifting cable 7 is fixed to removable manner in the vertical extension 22.
- the towing cable 12 is also linked to the anchor 11.
- the guide cable 10 and the lifting cable 7 have been introduced into the opening 19 of the front module 13 of a marine vehicle to be recovered, and are held there (for example under the effect of a trigger located at the entrance to the opening 19).
- the anchor 11 is brought closer to the front module 13, under the effect of the traction of the guide cable 10 (which is shortened, or due to movement of the marine vehicle).
- the arm 20 is introduced into a receiving housing 23.
- the receiving housing 23 is shaped to accommodate the arm 21.
- a mechanism, located in the housing 23, or on the arm 20 (or both), makes it possible to immobilize the arm 20 in the housing 23.
- the anchor 11 is thus rigidly fixed to the front module 13. This also has the consequence of positioning the connecting interface 14, in this case a hook, opposite the handle 21 to which it is ready to hang.
- the cooperation between the arm 20 and the anchor makes it possible to put the anchor precisely in position vis-à-vis the front module 13, so as to correctly position the hook so that the handle 21 engages it.
- the attachment with the front module is final, that is to say that the anchor cannot be released from the front module without human intervention, voluntary.
- a traction exerted on the lifting cable 7 has the consequences of separating said lifting cable 7, the end portion of which was linked to the guide cable 10, from said guide cable, and to engage the handle 21 in the hook.
- the handle 21 has been separated from the front module 13. It is brought in the direction of the lifting point of the marine vehicle, by pulling a handle cable 24, to be fixed there.
- a housing 25 may be installed at the lifting point of the marine vehicle, to form a lifting support.
- the housing 25 has an open face, and a lower hole 26 through which the handle cable 24 passes. exerted by the handle cable 24 on the handle 21 brings the handle 21 into the housing 25, in which it is introduced through the open face.
- the lifting cable not shown in Figures 19 to 21, begins to exert a vertical traction on the handle 21, which causes its straightening in the housing 25, illustrated in Figure 20.
- a notch 27 made in the upper face 28 of the housing 25 allows the passage of an upper element of the handle 21 (to which the lifting cable is linked via its end hook or other connecting interface).
- a base 29 of the handle is blocked in the housing 25.
- the marine vehicle can then be lifted by the lifting cable.
- the device allowing automatic fixing of the handle to the lifting point which is shown in Figures 19 to 21 is obviously only one possible embodiment. Others
- the system thus developed in the invention allows the recovery of a surface marine vehicle from a carrier boat. It can be used both for piloted marine vehicles and for unmanned, remotely operated or autonomous marine vehicles. In addition, the recovery of the marine vehicle can be achieved in rough seas, typically up to a sea state of Level 4 or 5 on the Douglas scale.
- the invention is based on a lifting means of the conventional davit type, which limits its cost, facilitates its implementation, and allows the system to be adapted to a pre-existing davit.
