- the ship can also be declined according to all the possibilities described.
- FIG. 1 represents a floating structure during towing having received an autonomous watercraft
- FIGS. 2 to 5 represent a system for deploying and recovering from a ship, an autonomous watercraft with a floating structure and showing the various stages of deployment (or, conversely, FIGS. recovery steps).
- a floating structure 1 is shown while towing on the sea (not shown), pulled from the bow by a towing cable 34.
- the floating structure comprises a hull consisting of a submersible bottom 12 and an inflated bead forming two side edges, a port side edge (G) 14 and a starboard side edge (D) 13.
- the side edges 13, 14 provide buoyancy of the floating structure 1.
- the submersible bottom 12 is drowned in particular due to the presence of an opening 17 at the rear of the floating structure 1, between the rear ends of the inflated bead forming the two side edges 13, 14. It is thus defined an interior space of the floating structure 1 and which is delimited by the inflated pudding and the submersible bottom, and where an autonomous aquatic machine can be housed.
- the inflated pudding may consist of several inflated pockets, sealed relative to each other, in the manner of commercial semi-rigid boats.
- the inflated bead increases the stability of the floating structure 1 while acting as a damping and protection against shocks that may occur between the floating structure and the vessel or the autonomous watercraft 2. It can be expected that when the floating structure 1 is delivered or, then, is not used and does not store the autonomous aquatic machine 2, it is disassembled and deflated to be stored under a small volume.
- the lateral edges may be other than an inflated bead and for example shells or parts of shells, in particular rigid, ensuring the buoyancy of the floating structure. Swollen portions may also be associated with shell portions.
- the hull of the floating structure 1 that is to say the part of this structure which is immersed, has a shape that gives the floating structure good navigability.
- This form allows in particular, when the floating structure 1 moves forward under the action of the towing cable 34, that it maintains a stable heading angle and angle of repose (i.e., a roll angle), and this at least up to a speed limit of 3 meters per second, or even up to a speed of 5 meters per second.
- a stable heading angle and angle of repose i.e., a roll angle
- the average fluctuations of the heading angle and those of the angle of lodging remain each less than 20 degrees, when the floating structure 1 moves forward at a speed less than or equal to said speed limit.
- the navigability of the floating structure 1 is also manifested when the amplitude of the swell is greater or when the wind forces.
- the hull of the floating structure 1 comprises a bow 24 which extends substantially vertically, from the floating line of the floating structure to the depth submarine bottom 12, forming a marked seashell joining a port portion and a starboard portion 21 of the hull.
- the port and starboard sides of the hull are concave, seen from the water, so that they join together forming a large rib 20 which facilitates penetration into the water and promotes maintaining the course of the floating structure 1.
- each side edge 13, 14 is provided at the rear of an optional flap 22, which extends substantially parallel to the longitudinal axis front-rear of the floating structure 1, and which plays a role in some way. a drift, or a fixed rudder.
- hull here designates the part of the floating structure 1 which is submerged, that is to say situated below the waterline, when the floating structure 1 is immobile and immobile with respect to with water (the autonomous aquatic machine 2 is then not housed in the interior space 18 mentioned above).
- the hull thus corresponds to the immersed part of the hull of the floating structure 1.
- the navigability of the floating structure 1 allows it to release or recover the autonomous aquatic machine 2 while the floating structure 1 and the autonomous water machine 2 advance to the surface of the water. This is interesting in particular because the autonomous aquatic machine 2 is more easily maneuverable when it moves, so it is easier to retrieve the autonomous watercraft 2 when the floating structure 1 and the machine advance all two, at moderate speed, on the surface of the water.
- the hull of the floating structure 1 is shaped so as to maintain said interior space 18 submerged at least in part, when the floating structure 1 moves forward, and this at least as long as a moving speed of the floating structure is less than the speed limit mentioned above.
- This specific conformation of the hull is important to allow a recovery in motion of the autonomous aquatic machine 2 (as explained above). Indeed, in the absence of any particular precaution, a displacement of the floating structure 1 towards the front, under the action of the towing cable 34, would cause the floating structure 1 to rise up and the water to be out of the water interior 18 for receiving the autonomous watercraft 1 (this planing is particularly marked because of the extent of the bottom 12 of the floating structure).
- the hull in order to avoid this setting water out of the interior volume 18, the hull is shaped more precisely to allow a water inlet to the front of this interior volume, when the floating structure 1 advance.
- the hull thus comprises, in the front part (that is to say closer to the bow than the stern), two water intakes 23, port and starboard, putting in communication said interior space 18 and the aquatic environment of the floating structure 1 (in Figure 1, only the starboard intake 23 is visible).
- These intakes 23 are made in the form of openings in the shell of the floating structure 1, located at least partly below the waterline of this structure.
- the hull may comprise one or more fins (not shown), optional, each oriented so that the flow of water exerts on the fin a force directed downwardly when the floating structure 1 moves forward.
- a floating autonomous watercraft 2 has simply introduced inside the floating structure 1 on the bottom 12 by a simple relative movement between the two because the back of the floating structure 1 is open and the submersible bottom 12 is drowned.
- a sufficient draft is provided between the lower part of the hull of the floating structure 1 and the bottom 12 (out keel which must pass through a slot / longitudinal middle opening of the bottom) to prevent the watercraft Autonomous 2 rubs on the bottom during this relative movement.
- the behaviors at sea of the floating structure 1 and the autonomous aquatic machine 2 are close to each other, there may be slightly different pitchings, rolls and / or inclinations between the two and this can be taken into account to define the height of this draft. It may be noted that, at the rear and laterally, the presence of the strand is a security in that, in the event of an impact at these levels between the floating structure 1 and the autonomous aquatic machine 2, some depreciation is obtained.
- the autonomous watercraft 2 When the floating structure 1 with the autonomous aquatic machine 2 inside will be raised out of the water, the autonomous watercraft 2 will come to rest on the bottom 12 of the floating structure 1 due to the disappearance of the water which caused it to float above the bottom when the floating structure 1 was at sea.
- the bottom 12 and, more generally, the floating structure 1 are not configured to store water during the ascent of the floating structure 1 on the ship.
- the autonomous aquatic machine 2 is floating here only but in other applications it can be mixed, that is to say it can have a floating state and a submerged state, the floating state being necessary for to introduce or leave the floating structure 1 except to provide a bottom 12 deep enough to be able to receive the autonomous watercraft 2 while it is underwater, in practice shallow dive.
- the submersible bottom 12 is substantially rigid.
- a flexible submersible bottom which forms an open pocket on the rear and can be enlarged to increase its height or shrink at will in order to receive the autonomous aquatic machine 2 in the manner of a fish in a fishing net.
- the autonomous watercraft 2 comprises a substantially fusiform hull with downwards a keel 10 submerged and up a booth 1 1 out of water.
- This autonomous watercraft 2 comprises integrated propulsion means allowing it to enter and exit the floating structure 1 and to move in or on the sea, as the case may be, autonomously, with pre-programmed evolutions and / or remote controlled.
- the floating structure 1 is intended to be reassembled on a ship or to be launched from a ship.
- a gantry 15 has been installed on the floating structure 1, a gantry with an articulated arm 16 connected to a maneuvering cable 33 in order to be able to lift the floating structure 1, possibly with the machine, through the control cable 33.
- autonomous water tank 2 inside.
- the gantry and, in particular the articulated arm 16 are arranged in an equilibrium zone so that when the floating structure 1 with the autonomous aquatic machine 2 inside is lifted out of the water, they remain substantially horizontal. Otherwise, the towing cable can help maintain the floating structure 1 horizontally.
- This stabilizer guide for the kiosk also forms here a stop for the front of the booth 1 1.
- This stabilizer guide for the kiosk is complementary to the longitudinal slot (not visible) median made through the bottom 12 and which allows the passage of the keel 10 and which also forms a guide and possibly a stop for the front of the keel 10.
- Means (not shown) for locking in position of the autonomous aquatic machine 2 in the floating structure 1 are provided. These locking means in position are removable and they are closed for recovery on board the vessel of the floating structure 1 with the autonomous water craft 2 inside and open when to release the autonomous aquatic machine at sea 2 while the floating structure was launched.
- These locking means in removable position act in particular on the keel (in the slot) and / or the kiosk (on the gantry 15).
- the floating structure is thus equipped with guides allowing the autonomous watercraft 2 to easily reach the interior space 18 and some of these guides may also be constituted by air bags and deflatable so that they could be used, when are inflated, to block the autonomous aquatic machine 2 when in position in the interior space 18.
- the towing cable 34 may comprise pipes, especially for pressurized gases, fuels, etc., and / or electrical conductors, in particular for a power supply and / or data transfers.
- the floating structure 1 can be is equipped with automatic connectors allowing an electrical connection between the machine 2 and the carrier ship when the craft is positioned in the interior space 18 of the floating structure 1.
- the floating structure 1 can also be equipped with automatic connectors allowing a data connection between the machine 2 and the floating structure 1 and / or the ship 3 when the machine 2 is positioned in the interior space 18 of the floating structure 1 .
- the floating structure 1 can also be equipped with automatic connectors allowing a fuel connection between the machine 2 and the floating structure 1 and / or the ship 3 when the vehicle 2 is positioned in the interior space 18 of the floating structure 1 , so that the machine can be refueled. It may be the same for other fluids such as pressurized gas.
- a floating structure 1 which can receive a It is however possible to construct a floating structure 1 which can receive two or even three autonomous aquatic machines 2.
- a longitudinal slot is provided through the bottom 12 and possibly a stabilizing guide for each kiosk 1 1.
- the autonomous aquatic machines 2 are stored parallel to each other, as previously longitudinally, in the floating structure 1.
- the inflated bead is configured to form a medial separator extended to the rear of the floating structure 1 as the side edges 13, 14, the inflated bead then has a similar shape to a W.
- This principle can be extended to three or more autonomous aquatic machines 2 and in this case the inflated pudding then has a comb shape.
- a vessel 3 carries on its rear deck 30 a floating structure 1 in which is installed an autonomous aquatic machine 2.
- the floating structure 1 is placed high on separate supports 31 so that the keel 10 finds its place on the rear axle 30.
- the keel 10 can be raised and lowered as needed as in the present case.
- the floating structure 1 and its autonomous aquatic machine 2 are fixed on the rear deck 30 by removable fixing means.
- a handling gantry 32 which is disposed at the rear of the rear axle 30, comprises a pulley on which the operating cable 33 is wound.
- the operating cable 33 can be wound up and unwound by a maneuvering winch 35.
- FIG. 3 the floating structure 1 and its autonomous aquatic machine 2 have been launched.
- the removable fastening means had been opened in order to release the floating structure 1.
- the operating cable 33 and the gantry 32 were maneuvered which allowed to lift the floating structure 1 and its autonomous watercraft 2 and then translate them to the rear of the ship 3 by tilting the gantry 32, to above the water where they were sunk. It may be noted that the towing cable 34 connects the floating structure 1 to the ship 3.
- the two side edges port and starboard floating do not meet at the front of the floating structure and the bow then corresponds to an opening at the front of the floating structure, the two side edges being united and secured by a transverse coupling and the floating structure is akin to a catamaran.
- part of the coupling between the two side edges is submersible and corresponding to the bottom.
- the two lateral edges may be two inflated tubes or two shells.
- the hull of this catamaran-type floating structure then comprises the bottom in question, and two parts of the two lateral edges which are submerged when the floating structure is immobile.
- this hull comprises, in the front part, a water intake, thanks to which the interior space 18 remains submerged, at least in part, when the floating structure moves forward.
- This water intake is in this case the front opening, mentioned above, defined between the port and starboard side edges.
- the floating structure 1 may be equipped with capabilities enabling it to navigate in a clean manner by boarding and under the direction of a staff. In this latter configuration it is equipped with a propulsion and a man-machine interface.
