Definitions

  • Embodiments of the present invention relate to a recovery device with increased range.
  • Preferred embodiments relate to a catamaran or SWATH (Twin Waterplane Area Twin Hull) recovery device with increased range.
  • SWATH vehicles are described, for example, in Wang, C, Y. Lin, Z. Hu, L. Geng and D. Li. "Hydrodynamic Analysis of a Swath Planing Usv Based on Cfd.” In OCEANS 2016 - Shanghai, 1 -4, 2016 examined.
  • the object of the present invention is to provide a recovery system which in itself offers an improved compromise of cost-effectiveness and operational capability.
  • Embodiments of the present invention provide a remote-controlled, semi-autonomous or autonomous recovery device having a drive configured to transport the recovery device along with the autonomous underwater vehicle over a long range, and with means for deployment and recovery.
  • an autonomous underwater vehicle does not necessarily have to be suspended from a mothership, but can also be suspended on land.
  • a recovery device which has a drive concept for a long range and at the same time is suitable for transporting, suspending and recovering an autonomous underwater vehicle. It is advantageous in this case that the autonomous underwater vehicle can no longer operate only in the vicinity of the mothership, but can also be sent independently from the same over many kilometers / nautical miles from land. As a result, the use of expensive mother ships can be largely avoided.
  • a long range usually means a range in the range of 500 nautical miles or even 1000 nautical miles. In general, a long range means at least 5 nautical miles or 12 nautical miles, or in the smallest case around the five nautical miles.
  • the drive of the recovery device comprises either an internal combustion engine with a sufficiently large fuel tank, eg 100 or 500 liters, to achieve the high range or an electric motor with a sufficiently large-sized battery.
  • a battery it is also possible to provide a generator with a corresponding fuel tank.
  • an energy generator such as a solar cell can be arranged on the autonomous underwater vehicle, which generates the necessary energy for transport or generally for the operation.
  • the recovery device comprises a control that ensures the autonomous or semi-autonomous operation.
  • This control can access a sensor system, which is also part of the recovery device.
  • This sensor may include, for example, cameras or GPS sensors.
  • the controller may be configured not only to partially autonomously or autonomously control the route, but also to maneuver such as e.g. perform the landing maneuver.
  • the controller is also adapted to operate autonomously, e.g. if the investigation area for the autonomous underwater vehicle is reached, suspend it and recover it after the mission has been completed.
  • the recovery device comprises means, e.g. Fender, to allow the recovery device to land, e.g. to a bridge, or to a mothership can create.
  • the autonomous recovery device for the autonomous underwater vehicle serves as a charging station.
  • energy can be taken from the autonomous recovery device and transferred to the autonomous underwater vehicle, so that it performs several missions in succession.
  • the autonomous underwater vehicle can exchange not only energy but also data with the autonomous underwater vehicle and transmit it, for example, to a base station.
  • the autonomous recovery device forms a kind of repeater, e.g. on radio basis, for the autonomous underwater vehicle.
  • the recovery device may comprise means which make it possible to improve the location of the AUV, in particular in underwater operation.
  • These include, for example, transmitter and receiver or a so-called hydrophone, which, for example, forward the GPS signals under water.
  • transmitters and receivers or the hydrophone are arranged under the water surface and allow the location according to the principle of USBL (ultra-short baseline) or LBL (long baseline) concepts.
  • the recovery device has two hulls (Katamaranform or SWATH shape) and between the two hulls arranged (fixed) safety net for receiving an autonomous underwater vehicle, the safety net is lowered from a non-lowered state to a lowered state, so that the autonomous vessel in the lowered state can be received and transported in the non-lowered state.
  • the reverse movement from the lowered and not lowered state is then carried out during the actual recovery process.
  • This principle offers two major advantages, namely that the catamaran moves with the waves, so that an AUV can be safely and reliably salvaged even at high seas.
  • the network is e.g. by means of one or more electric winches / motors lowered and raised, so that here no additional action of personnel is necessary.
  • the recovery device is extended by having a winch for retrieving the AUV in the space between the two hulls.
  • a winch for retrieving the AUV in the space between the two hulls.

  • the method may also include the optional step of "retrieving the AUV” 30 or "AUV retracting" 130.
