  • Patent number: 11249481
    Abstract: A method for transporting a parcel comprises a marine unmanned vehicle (MUMV) receiving a waterproof tote, coupling the tote to a tether, and towing the tether and the tote, with the tether floating on the transport waterway and the tote immersed in the the transport waterway, to a delivery location. The method can include an MUMV receiving the tote from, and/or delivering the tote to, an aerial vehicle. An unmanned water transport system (UWTS) comprises an MUMV, a floating tether, and a waterproof tote containing a parcel for transport on a transport waterway. The MUMV and tether are configured to tow the tether, with the tether floating on the transport waterway, and the tote coupled to the tether and immersed in the water of the transport waterway, to transport the tote from a source location to a delivery location on the transport waterway. The UWTS can perform the method.

  • Patent number: 9701385
    Abstract: A PTB system includes a vessel (barge) having propulsion and maneuvering gears (shaft & propeller) without an engine or power source. The PTB system further includes a tug having a generator and a fuel source that powers the generator for supplying a power pack to power the propulsion and maneuvering gears onboard the barge. The propulsion and maneuvering gears may be remotely controlled and the vessel will be powered by the tug's power pack, and not from a generator (or other power source) onboard the vessel. The tug will be connected at the bow of the vessel rather than at the aft of the vessel (like in a traditional ATB system), wherein the vessel's entire propulsion power comes from the tug's onboard power pack. The vessel will push the smaller tug, which supplies all its propulsion power to the vessel.

  • Patent number: 8825241
    Abstract: This invention provides a vessel system and methodology that can be used to promote growth of phytoplankton in the oceans. Unmanned self-controlled wave-powered vessels are equipped with storage units for dispensing a fertilizer, and with sensors to monitor ocean conditions and effects. Fleets of vessels move autonomously by on-board processing of GPS and directional information, piloting a path that is coordinated by a central processing unit. The vessels travel through a defined target area, creating a detailed survey of chemical and biological characteristics that affect grown. The data are processed in a computer model to identify precise locations and precise amounts of fertilizer that will produce the best results. Projected benefits of fertilizing plankton include sequestering CO2 from the atmosphere, and enhancing the marine food chain to improve the fish stock in and around the treated area.

  • Publication number: 20130199433
    Abstract: The invention relates to a positively buoyant wave generator adapted to travel through a body of water, wherein specific features are incorporated into the wave generator to help create and off-set various hydrodynamic forces that can act on the wave generator as it travels through the water. Rather than eliminating these hydrodynamic forces, the invention seeks to create and counter these forces, which has been found to help keep the wave generator in substantial equilibrium. For example, a connecting member can be extended forward and below the wave generator's center of buoyancy, such that as the wave generator is pulled, it creates an upward force that helps to counter a downward force acting on the front end of the wave generator as water is lifted up. Various internal moments can also be created and off-set by adjusting the center of gravity and/or center of buoyancy and using these forces to help keep the wave generator in substantial equilibrium.

  • Patent number: 8275493
    Abstract: A system and method are provided for launching and recovering an unmanned, water-born vehicle (UWBV) from a mother ship. The UWBV mimics the behavior of dolphins and is positioned ahead of the ship in preparation for bow riding. The UWBV uses a guidance system to position and keep in the bow wave. A high-frequency (HF) sonar transceiver array aboard the ship computes and sends course corrections to maintain the UWBV within the bow wave. The frequency range of the HF array can be 100 kHz or higher due to the short distance between the ship and the UWBV. Accordingly, the HF array can have a small aperture allowing for accurate bearing resolution. Course corrections can be sent on a near-continuous basis such that changes in thrust and rudder angle can be minimized to allow for accurate control of the UWBV.

    Abstract: A wake tower for a powerboat for use in wakeboarding or other water sports is described. The wake tower can include base members attached to the powerboat and a U- shaped bar extending generally upwardly from the base members. The side bars can be tapered inward and can also be angled toward the bow of the powerboat. Support members can be positioned along the side bars to provide increased structural support to increase the maximum load of the wake tower and to increase the rigidity of the wake tower resulting in less shaking during use. A tow cross bar having a tow rope connector can be suspended generally between the side bars of the wake tower. The wake tower can be transitioned between an upright position and a lowered position. Shocks can be used to compensate for some of the weight of the wake tower to allow the wake tower to be raised and lowered with less effort by the user.

    Abstract: A method of moving a floating wind turbine relative to a body of water, the floating wind turbine having a buoyant body with a nacelle at the upper end thereof, including the steps of floating the floating wind turbine in the body of water, and towing the floating wind turbine whilst holding the buoyant body in an inclined position, whereby the nacelle is held clear of the water. As the wind turbine is held in an inclined position, it can be towed through regions of shallower water than if it were in a vertical position.

    Abstract: An aquatic device (10) for providing maneuverability to a user (11) moving in water. The aquatic device (10) may be propelled through the water in any appropriate way, such as by being towed through the water or propelled through the water by the user (11). The aquatic device (10) comprises a handle means (20) adapted to be grasped by the user (11) with arms extending forwardly, and two fins (21, 22) movable one with respect of one to the other to manoeuvre the aquatic device. The aquatic device (10) can be maneuvered through movement of the fins (21, 22) to provide directional control or variation to the orientation of the aquatic device. The directional control may include both steering and depth control. The handle means (20) are operably connected to the two fins (21, 22) whereby the user can manually control movement of the fins one with respect to the other.

  • Publication number: 20100319603
    Abstract: A towing apparatus comprises a structural assembly extending between opposing first and second bases for pivoting between operating and stored positions. A locking assembly includes a pin in each base and a hook carried at opposing ends of the structural assembly. A cam is pivotally connected to the hook for movement between locked and released positions. In the locked position, the hook is secured to the pin for preventing rotation of the structural assembly. In the released position, the hook is spaced from the pin to permit rotation of the structural assembly. The hook is rotatable with the cam from the released position to adjacent the pin by rotation of a shaft and slidable along the pin into the locking position by a continued shaft rotation. A cable is attached between the base and a spring within the structural assembly for biasing the structural assembly toward the operating position.
