Anchoring Arrangement Patents (Class 114/293)
  • Patent number: 10150545
    Abstract: A wave-powered water vehicle includes a surface float, a submerged swimmer, and a tether which connects the float and the swimmer, so that the swimmer moves up and down as a result of wave motion. The swimmer includes one or more fins which interact with the water as the swimmer moves up and down, and generate forces which propel the vehicle forward. The vehicle, which need not be manned, can carry communication and control equipment so that it can follow a course directed by signals sent to it, and so that it can record or transmit data from sensors on the vehicle.

  • Patent number: 9815532
    Abstract: The present invention provides an anchor alarm device which is a manually deployed weighted device attached to or near the anchor which signals to device equipment at water-level. The device detects the movement of, or physical force generated by, a dislodged anchor. When deployed, a component of the anchor alarm device rests adjacent to or as part of a seated anchor at a distance predetermined by the tolerance of the secondary rode. The secondary rode connects the device directly to the anchor, or near the anchor on the primary rode. Upon displacement of the set anchor, in excess of the secondary rode, the device alerts the user. The device utilizes sensor monitoring inside of a housing component to detect a force indicative of anchor displacement. This detection triggers a signals emission which alerts the user of the change in position. In cases wherein the anchor is not immediately retrieved, device re-arms autonomously and stops emission of the alarm signal until the next anchor displacement.

    Abstract: An underwater apparatus for generating electric power from ocean currents and deep water tides. A submersible platform including two or more power pods, each having a rotor with fixed-pitch blades, with drivetrains housed in pressure vessels that are connected by a transverse structure providing buoyancy, which can be a wing depressor, hydrofoil, truss, or faired tube. The platform is connected to anchors on the seafloor by forward mooring lines and a vertical mooring line that restricts the depth of the device in the water column. The platform operates using passive, rather than active, depth control. The wing depressor, along with rotor drag loads, ensures the platform seeks the desired operational current velocity. The rotors are directly coupled to a hydraulic pump that drives at least one constant-speed hydraulic-motor generator set and enables hydraulic braking. A fluidic bearing decouples non-torque rotor loads to the main shaft driving the hydraulic pumps.

    Abstract: A system of floating and weight-stabilized wind turbine towers with separately floodable compartments and aerodynamic overwater encasement and the appertaining semisubmersible mooring structures including anchorage on the seabed, a horizontally floating underwater mooring meshwork and an actinomorphic buoy-cable-mooring to the wind turbine towers. Also, a method to transport wind turbine towers from the manufacturing plants on-shore to the final off-shore destination by towing the vented towers in a horizontal position with towboats. Further, a method to erect the wind turbine towers at the final destination, including the assembly of the wind turbines. The worldwide potentials of off-shore wind farming in deep waters to produce electricity in an ecologically and economically sound way in order both to satisfy men's requirements and to help to reduce the need to rely on critical fossil and nuclear resources being immense.

  • Publication number: 20130104790
    Abstract: A shallow water anchor is provided. The shallow water anchor comprises a first anchor extension and a second anchor extension axially received by a housing. The first anchor extension is axially received by the second anchor extension such that the first and second anchor extensions are sequentially deployable from the housing using an actuation arrangement. The actuation arrangement is controlled by a control interface that is operable to detect when the shallow water anchor has reached a fully extended state and fully retracted state. The shallow water anchor further includes a biasing compensator that compensates for fluctuations in the overall depth of water the anchor is deployed in due to waves or other anomalies.

  • Patent number: 8376790
    Abstract: A wave-powered water vehicle includes a surface float, a submerged swimmer, and a tether which connects the float and the swimmer, so that the swimmer moves up and down as a result of wave motion. The swimmer includes one or more fins which interact with the water as the swimmer moves up and down, and generate forces which propel the vehicle forward. The vehicle, which need not be manned, can carry communication and control equipment so that it can follow a course directed by signals sent to it, and so that it can record or transmit data from sensors on the vehicle.

  • Patent number: 8347806
    Abstract: An anchor retrieval system for manually retrieving a submerged anchor without requiring heavy pulling includes an anchor retrieval apparatus generally in the form of a clip formed from cylindrical stainless steel fabricated into a unique shape the permits the device to be quickly connected to an anchor line by a simple sliding motion. The clip is further adapted by the attachment of a buoyant member, such as a buoy, to provide a buoyant lifting force. Once the clip is connected to the anchor line anchor retrieval system is tossed into the water and travels down the anchor line as the boat motors away from the buoy until the buoyant force lifts the anchor from the sea floor, whereafter the anchor line is manually drawn in to the boat as the anchor is buoyantly suspended near the surface.

  • Publication number: 20120304911
    Abstract: A dynamic anchoring system for use in stabilizing a floating platform is provided. The dynamic anchoring system includes a mooring assembly having a plurality of rodes each with an adjustable length. As waves cause the platform to rock, the length of each rode is adjusted in a manner to counteract the motion created by the waves. Thus, the platform remains substantially level. The platform supports a wind turbine on a mast. At least one motion sensor on the mast provides motion data indication the direction and speed of the hull's motion.
