  • Patent number: 6994048
    Abstract: A barrier for small boats has a plurality of flotation modules on lines extending across a waterway. The flotation modules are cast from a buoyant concrete mixture of cement, water, beaded forms of expanded polystyrene, and polypropylene fibers that is non-water-absorbing, crushable, not susceptible to failure in shear, and has a density lighter than water. The mixture can have cement with the beads in a ratio of about 1:3.5 by volume, the water with the cement in a ratio of about 0.5 (1:2) by weight and the fibers with the cement in a ratio of about 1:141 by weight. Lines pass thru the flotation modules and slip upon impact of a flotation module by a speeding boat, and the buoyant concrete mixture crushes to absorb some energy of the impact. The barrier is relatively low cost, can be made next to a waterway from readily available materials by unskilled workers and is deployed in a minimum amount of time.

  • Patent number: 6745714
    Abstract: A floating drive on dry dock includes a variable buoyancy beam positioned below the deck of the dock. The beam is formed of separate cells that can be filled with air from a common feeder line. Separate inlet risers allow air into each cell. As the air moves into each cell, water is displaced out an opening in the bottom of the cell. The flow of air and water is restricted or damped to assure even filling of the cells in a beam. The feeder line and risers can be back filled with water to limit air flow between cells. Multiple beams can be used to achieve the desired buoyancy.

  • Patent number: 6409431
    Abstract: A submersible floating dock which can be sunk beneath the water line in the event of the approach of a violent storm for protection of the dock against wave action, storm surge, and high winds. A dock with a deck supported on hollow floatation chambers is attached to pilings by rings. The rings allow the dock to move up and down in response to changes in the water level. As a storm approaches water is allowed to enter the hollow floatation chambers which are ordinarily filled with air. This causes the dock and deck to sink beneath the water line making it resistent to damage from storm surge, wave action, and high winds. After the storm has passed, pressurized air is introduced into the floatation chambers forcing the water in the floatation chambers out of the chamber. The air increases the buoyancy of the floatation chambers, hence, of the dock so that it rises above the water line for use by an owner after the danger of storm surge, high winds, and waves has passed.

    Abstract: A dock module comprises an air-tight flotation chamber with a buoyant foam material positioned within an upper end thereof. The flotation chamber includes aperture positioned on its bottom end to permit water to enter the chamber and serve as a ballast. To float the dock module, compressed air is injected into the flotation chamber to increase the module's buoyancy and adjust its freeboard so that the buoyant foam is lifted completely above the water contained within the flotation chamber. If the air-tight flotation chamber fails, the buoyant foam will prevent the dock module from becoming submerged. Each module comprises a plurality of longitudinally and laterally extending tubes that can be used to attach the module to a like module using tubular couplers and tensioned cabling. Multiple modules can thus be joined in any desired configuration to yield a floating dock system having virtually any desired geometry.

  • Patent number: 5282435
    Abstract: A device for maintaining docks or other floating bodies at a given distance from and orientation to the shore by means of a ratchet assembly hinged on the side of the dock closest to shore, and a line attached to two guides, such as pulleys, on the underside of the dock. When the level of the water varies, the device maintains the dock at the same distance from the new waterline as it was from the old, in the following manner: the line is anchored at one end on shore and at the other to a bottom anchor beyond the farthest point the dock will extend to at lowest water level. Tension in the line pushes the dock towards the shore until the ratchet contacts the bottom, where equilibrium is established. If the water falls, the ratchet pushes the dock away from shore and a new equilibrium is established, farther out; this repeats as long as the water falls. If the level rises, the ratchet is raised off the bottom and the dock moves towards shore to a new equilibrium point. This continues as long as the water rises.
