Definitions

  • the current invention relates to non-lethal defense system and means for ships to immobilize small watercraft.
  • the entanglement net is directly coupled to the hulls and both hulls are at the same depth as the entanglement net. This will have a high chance of hitting the watercraft with the hull itself. In case of a head on or sideway interception, such collision would be catastrophic, which is undesirable.
  • a system for immobilizing small watercraft comprises an underwater vehicle equiped with a structure to deliver a crippling effect to the propulsion mechanism of the watercraft.
  • the vehicle is either self propelled or towed with a winch system.
  • the structure for delivering crippling effect is either an entanglement device or a bumper for ramming the propeller. The vehicle is maintain onboard the ship and deployed in the water as soon as the threat is detected.
  • the vehicle In case of a pirate boarding attack, the vehicle is launced and set waiting close to the ship behind where the pirate boat is heading. As the boat is about to be running next to the ship, the vehicle is brought forward alongside the ship, engage the boat and immobilize it.
  • the launched vehicle is guided to intercept and immobilize the target watercraft at a distance from the ship.
  • the guiding can be done using a homing guidance onboard the vehicle or an inertial guidance, with tracking information provided by the ship.
  • FIG. 1 depicts a towed vehicle 100 in use as an illustration of the general method.
  • FIGS. 2A-2C depict an embodiment of a towed vehicle 100.
  • FIG. 3 depicts the first embodiment of a winch system.

  • FIGS. 9A-9B depict another embodiment of UUV 600.
  • FIGS. 10A-10G depict yet another embodiment of UUV 700.
  • the cable serves as a means for both driving and guiding.
  • the vehicle may even further use the side of the ship as a guide so active steering is not required.
  • remotely controlled steering may allow for some off-course chasing capability.
  • the depth control mechanism can be preset as well for proper delivery of the crippling effect.
  • the winch system is pulling the vehicle from close to the bow and uses a guiding arm adjustable for different draft conditions. When not in use, this guiding arm can be retracted or folded up to reduce drag. To be stealth, this arm is completely underwater. Advantage of this approach is a low cost, low maintenance vehicle.
  • the vehicle In an UUV configuration, the vehicle has onboard propulsion and steering. This means minimal or even no modification to the hull of the operating ship - a factor likely more appealing for ships already in service.
  • the UUV can be controlled remotely by manual adjustment in steering and propulsion.
  • the depth control mechanism can be preset but might just as well be made adjustable. Even though in this configuration, a tether cable between the vehicle and the ship is not required, such a cable could provide many additional benefits. It allows the vehicle to conserve power while waiting for the attacker to approach. It can be used to help with retrieval of the vehicle after the mission. It can also serve as a restraint to ensure that the vehicle will not hit and damage the ship's own propeller. For better serviceability, the signal wire for remote control may be combined and built into this tether cable.
  • the embodiments in the UUV configuration can further include a guiding or even homing mechanism on board whereby the UUV can intercept the watercraft and immobilize it at a good distance form the ship.
  • a camera system is used to provide surveillance so the operating crew can stay in the safe citadel.
  • the camera can be mounted at high spots on the ship such as by the bridge or on an unmanned aerial vehicle drone.
  • one or more light sources are mounted on some of the embodiments. These light souces only emit light invisible to the human eye so as to keep the adversaries uninformed.
  • a motion control subsystem can be used to coordinate the steering and other functions. This control system can incorporate data such as water flow parameters around the ship. Position of the vehicle relative to the ship can, for example, be extracted from processing the surveillance image or using a sonar. It is within the capability for those skilled in the art to implement such a subsystem. By doing so, the system does not requires skilled steering, and the operation can be as easy as entering a position referenced to the ship and hitting a go button.

  • FIG. 2C depicts a side view of towed vehicle 100 moving forward toward propeller 212 of watercraft 210.

  • vehicle 100 is deployed before watercraft 210 is anywhere near ship 200. Referring to FIG. 1, vehicle 100 waits by the stern. The operation can be simply hitting the start button at the right moment for the winch system to tow vehicle 100 toward the bow of ship 200. Vehicle 100 bumps and disables watercraft 210, pushes it away from ship 200, keeps going for other watercraft ahead or moves back to the stern area until all threat is cleared.

  • Body 302 holds multiple pieces of entanglement device 314 in a roll, with weak links in between pieces.
  • Depth control subsystem 310 is onboard body 302.
  • Entanglement device 314 is positively buoyant such that it floats toward the water surface to form a shallow scooping net, ready to snare a propeller in its path. Therefore, remote control in depth change is not needed in this embodiment.

  • Two light sources 407 are mounted on the hulls 402A and 402B.
  • the depth control also includes ballast systems 410 and hydrofoils 412. In operation, as soon as watercraft 210 comes within range, towed vehicle 400 is maneuvered to be underneath propeller 212.
  • Cable 122 also houses the control signal link (e.g., a coaxial cable with steel strands forming a tension bearing shell with electrical wires in the middle).
  • Front bumper 405 is added as an option for taking out watercraft quickly when hard pressed. It can be as simple as a wide bar, or multiple bars (as shown here) to accomodate variation in depth of propellers.

  • Embodiments such as UUVs 500, 600 and 700 can be used for such applications. Due to the reason that the entanglement devices and wide bumper areas allow a large margin of aiming error, a non- homing type of guidance system can be used on the UUVs. Means onboard the operating ship, such as sonar or visual surveillance, can be used to extract the position and velocity of both the UUVs and the watercrafts. Programs onboard the operating ship can then guide the UUVs with motion commands for interception. Of course, the UUVs can further include an onboard homing guidance mechanism, which is well known in the art.
  • the presented methods greatly increase the prospect of success while being very simple to operate.
  • the system takes advantage of stealth so the adversaries will not be able to counteract easily. It will achieve a speedy termination of the threat, while not putting the targeted personnel in danger. It does not add burden to the ship when no threat is present, and consumes only minimal energy during operation.

Abstract

Système et procédé destinés à un grand navire (200) pour immobiliser une petite embarcation malveillante (210) se composant d'un véhicule sous-marin sans pilote (100, 300, 400, 500, 600, 700). Le véhicule (100, 300, 400, 500, 600, 700) peut être lancé dès la détection de la menace. Lorsque l'embarcation (210) s'approche, se préparant à monter à l'abordage, le véhicule (100, 300, 400, 500, 600, 700) utilise son système de propulsion embarqué (504, 604, 704) ou est tracté par un câble (120, 122) pour s'approcher sans bruit de l'embarcation (210) et pour produire un effet d'immobilisation, tel qu'un accident violent ou un accrochage de blocage, sur le mécanisme de propulsion (212) de l'embarcation (210).
