Anchor Patents (Class 114/294)
  • Patent number: 11945549
    Abstract: A method for installing a TLP based floating object at anchor points. The floating object includes a central body and buoyancy assemblies positioned around the central body in a horizontal plane, with each buoyancy assembly connected to the central body and connectable to one of the anchor points. The method includes: attaching a mooring leg including a mooring line at each anchor point; for each anchor point connecting a pull-down line between the buoyancy assembly and the anchor point; tensioning the pull-down lines so the floating object is lowered to an installation level below an operational level; for each anchor point connecting the mooring leg with the buoyancy assembly in slack mode; and after connecting the mooring lines with the buoyancy assemblies, paying out the pull-down lines so the floating object rises upward from the installation level to the operational level where the mooring legs are tensioned.

  • Patent number: 11927003
    Abstract: The present disclosure is directed to an apparatus, system, or method for covering and utilizing a plunger. The plunger can be inserted into a cover configured or sized to receive the plunger. The cover is attached to a handle with a closure mechanism. The closure mechanism is used to close the open end of the cover after removal of the plunger from the cover. A toilet or other drain or pipe system may be unclogged using the covered plunger. When the plunger and the cover are removed from a toilet, and the plunger is removed from the cover, the cover reverses or inverts. When reversed or inverted, the cover contains water or waste material from the toilet within the cover.

  • Patent number: 11827314
    Abstract: The present invention relates to a hybrid dynamically installed anchor with a folding shank and a control method to keep the verticality of the hybrid anchor during free fall in the seawater, which can be applied to the field of offshore engineering. The hybrid anchor comprises a folding-shank plate anchor, a ballast shaft, an extension rod, a plurality of rear fins, and a recovery hole from the front to the tail. The folding shank is not only useful in reducing the water and soil resistance during installation, but also beneficial in improving the directional stability of the hybrid anchor during free fall in the seawater. The re-used shaft can significantly increase the penetration depth of the folding-shank plate anchor and reduce the installation cost at the same time. The control method keeping the verticality of the hybrid anchor can improve the success rate during anchor installation.

    Abstract: A buoy and mooring system provides a robust buoy protective of markings thereon, easily retrieved for inspection and service, weighted and levered for maintaining self-righting, vertical orientation and anchored with a non-corroding system of connectors and links running from surface to sea floor. A mid-line float resists entanglement, and can be installed or uninstalled by operation of various “worm grip” mechanisms. A slack line region accommodates changing tides. An upright tube, weighted at a lower end and flanged at an upper end thereof, secures a buoy in place but pulls up through the buoy for easy retrieval by boat crews. Embedding an anchor is by hydraulic water jet drilling. From a thimble in the anchor to a thimble in the upright at the buoy, no intervening metal components are needed in the load path. Markings are durably and protectively embedded in recesses below the buoy's outer surface.

  • Patent number: 9156527
    Abstract: An anchor pin for anchoring small water vessels is provided. The anchor pin includes at least an upper pole and a lower pole that may telescope relative to one another. The upper pole may include a substantially hollow center in which the lower pole may be inserted into. The lower pole may slide within the upper pole and may thereby telescope relative to the upper pole. The lower pole may be locked in a fixed position relative to the upper pole so that the anchor pin may be set at a desired length to anchor the water vessel. The water vessel may be attached to the anchor pin by a rope.

  • Patent number: 9073609
    Abstract: The present invention is directed to an apparatus that allows a boat to be anchored and keeled. The invention has a member that can rotate about a first axis from a stowed position to an anchored position. Or the members may be placed downwardly in the ground floor of the body of water, for keeling. The hull of the vessel has a channel for the rotation or movement of the member within the channel.

  • Publication number: 20150144050
    Abstract: The invention is an anchor which constitutes a certain weight in the water, when dropped into the water by means of a connection like a rope or chain connected to the mentioned vessel in order to stabilize the vessels at a required area or point over the sea surface. It has an expandable reservoir which allows the water transmission inside from the outside, keeps the material located inside and is connected to the vessel with the connection and contains a water absorbent material which expands and gets heavy when interacting with water located in the reservoir. When the water absorbent material interacts with water it turns into a mass of thick solid gel and becomes heavier inside the reservoir in which it is located, and reaches the sufficient weight that the reservoir can stabilize the vessel at its place.

  • Patent number: 9016225
    Abstract: A kayak mooring stake is positioned in a scupper hole or sleeve. A knob is provided on the stake, and the knob rests on a shelf or ledge around the inside surface of the scupper hole or sleeve. When the mooring stake is rotated, the knob is positioned over an essentially vertical slot interrupting the ledge or shelf, and the stake can be thrust through the scupper hole or sleeve into the mud/sand at the bottom of a bay, lake, stream or the like, thereby fixing the position of a small watercraft against wind and/or current.

  • Patent number: 8973594
    Abstract: Described is tent peg that provides easy storage and transport to reduce the likelihood of the tent peg being lost. The tent peg comprises a shaft having and a head comprising a body having an arm extending therefrom. The arm comprises a first aperture adjacent to the body and a second aperture located between the first aperture and a distal end of the arm. The first aperture is formed to receive a shaft of a first further tent peg in an opposite orientation. Additionally, the second aperture is formed to receive a shaft of a second further tent peg in the same orientation as the tent beg. Further, the shaft of the second further tent peg is receivable in a first aperture of the first further tent peg. Therefore, multiple tent pegs can be interconnected with each tent peg in the opposite orientation to the adjacent tent pegs.

  • Patent number: 8950352
    Abstract: The invention comprises an anchor including a shank which in cross section along at least part of its length has forward and rearward facing edges and a pair of side faces between said edges. The parts of the shank adjacent the forward edge are substantially “v” shaped in cross section and at least part of the side faces between the edges are concave. The anchor further includes a fluke having a forward end and a rearward edge in normal use, the rearward edge having a continuous flange extending therefrom over at least a substantial part of the rearward edge. The anchor has a roll-bar positioned substantially above the upper surface of the fluke forming a semi-circular wheel spanning the width of the fluke and wherein along at least a substantial part of its length the roll-bar is in cross section substantially in the form of a foil.

  • Patent number: 8869746
    Abstract: A structure for underwater placement on a sea, lake or river bottom. The structure has tunnels to allow water and water currents, as well as marine organisms, to pass freely therethrough and infiltrate and colonize the openings. One or more hitch points are provided on the structure for attaching mooring lines to ships, boats, floating wind turbines or other floating objects, thereby allowing the structure to serve as a mooring to anchor such objects. The hitch points can be recessed within a depression in the surface of the structure and the hitch bar ends can also be recessed, providing an exterior surface free of protuberances.
