Definitions

  • the invention is in the naval field and relates more specifically to handling systems and lifting mounted on ships, allowing the launching and recovery of marine gear or submarine from these vessels, the gear considered being both towed gear and autonomous gear, the latter then being provided with a temporary link during the launching and recovery phases.
  • the invention relates more particularly to a system according to the preamble of claim 1.
  • a system is known from the document US 7,712,429 B1 which represents the closest prior art.
  • solutions generally implementing means that involve the intervention of human operators.
  • a known solution consists in providing means of securing on the the hull of the machine, for example fixing rings, these fixing means being arranged in such a way that the machine can be lifted while keeping a horizontal position.
  • the launching and the recovery can then, for example, be carried out by means of a winch mounted on a movable gantry placed at the rear of the ship, or a crane, the crane or the crane allowing to position the hoist winch above the recovery area.
  • the launch and the lift are carried out vertically which limits the possibilities of collision with the ship during the descent or ascent.
  • the lifting of the machine can be achieved by placing it in a nacelle type device itself having appropriate fixing points.
  • This type of solution is applicable, notably independently, to gear towed by the medium but is however not easily applicable to the case of gear towed from the front, insofar as, for obvious reasons of efficiency, it is desired to perform the towing and handling of the machine from a single cable.
  • Handling by means such as those described above using a single cable proves tricky because it is accompanied for the machine a passage from the vertical position to the horizontal position when setting the water and vice versa during recovery.
  • This handling also requires additional operations whose object is, after lifting the machine and positioning above the deck of the ship, to rest the craft flat on the deck of the ship or more generally on a storage area. These operations themselves usually require the intervention of human operators, intervention which is made more delicate and more dangerous by strong sea.
  • the generally preferred solution is to use a handling cable temporarily hung above the center of gravity of the machine.
  • a solution also used provides a handling based on the establishment of means having an inclined ramp on which the machine slides to reach the surface of the water or to get out and return to the ship.
  • the ramp is generally configured so as to guide the machine in a rectilinear path, which prevents the machine can follow a lateral movement.
  • a ramp is not generally not suitable for use by high seas, lateral movements of the machine may then cause damage to it.
  • the implementation of such means comprises a critical phase which is between the moment when the machine comes into contact with the ramp and that where it is completely placed on it. Indeed, the passage of the machine from the surface of the water to the ramp involves contacting the nose of the machine with the ramp, the entry into contact may occur, in particular agitated sea, with a certain hardness that can cause damage to the machine but also prevent the recovery of it.
  • An object of the invention is to provide means for launching and recovering a marine or underwater craft in the safest possible manner, these means can be implemented fully automatically, without intervention or human supervision.
  • An object of the invention is more particularly to propose means adapted to the handling underwater vehicles towed from the front or underwater gear not having means for vertical lifting, but being temporarily connected to traction means, a cable moved by a winch for example, during launching phases and recovery.

  • the ramp also comprises buoyancy means configured and arranged on the ramp so that the free end of the ramp floats on the surface or near the surface of the water when the ramp is lowered.
  • the bottom of the articulated ramp has an outer face forming a fairing having a sectional profile in the shape of a V or W so as to minimize the drag and lift forces imposed on the ramp by the movement of the vessel and the vertical dynamic movements caused by waves when its free end is in contact with water.
  • reception and guidance means comprising a reception device configured to receive the end of the machine and stay in contact with the machine during the launching and recovery operations, the reception device being driven with the vehicle by the traction means.
  • the reception device comprises vertical protection elements intended to offer a frontal support to the wings of the vehicle when its end is engaged in the reception device, the frontal support thus realized to contribute to the maintenance of the machine in the axis of the ramp.
