  • Publication number: 20240183641
    Abstract: A floating barrier system has a plurality of connected floating barrier units. Capture net segments are positioned on the floating barrier units by support post members, forming a barrier to vessel passage. Lanyards attach the ends of the capture net segments to the floating barrier units. Upon a vessel striking the capture net segments with sufficient force, the capture nets detach from the support post members and/or pull the support post members over, and the forces from the vessel are transferred via the lanyards to the floating barrier unit. The vessel is prevented from fully passing over the floating barrier unit, thus itself forming a barrier to passage by other vessels.

  • Publication number: 20230384063
    Abstract: A waterbody access barrier system has one or more floating barrier segments, and a first floating gate segment for blocking an opening in the barrier system. The first floating gate segment has a latching system to connect it to a capture gear, which is at a fixed barrier termination point or on a second floating gate segment. One or more thrusters are mounted on at least the first floating gate segment. The latching system, and the thrusters, are autonomously or semi-autonomously controlled by a control system, which receives positional signals, for example from a global positioning system (GPS) and/or a light detection and ranging system (LiDAR) operatively connected to the first floating gate segment, and moves the first floating gate segment accordingly.

  • Publication number: 20230023351
    Abstract: A floating barrier float section, and a waterfront barrier system formed from a number of connected float sections. An elongated main flotation tube has radially outwardly extending fence posts with connecting members, such as nets, between them, forming multiple longitudinal net sections about the circumference of the flotation tube, at least one of the net sections extending upwardly and forming a barrier to vessel passage. A vessel strike tends to rotate the flotation tube about its longitudinal axis, absorbing the energy from the strike and rotating the flotation tube to bring another net section into position. An underwater ballast member and a stabilizer float member may be added for additional resistance to rotation.

  • Publication number: 20150110546
    Abstract: A connector especially suited for connecting sections of floating port security barriers (PSBs) has a central portion joining two spaced apart, generally transverse end sections. The connector has a generally I-shaped cross section shape. Bolts or other fastening members are inserted through holes in the end sections to permit attachment to the PSB sections. The connector is preferably of a cast monolithic structure of a flexible, strong, non-corrosive material such as urethane. High-strength embedments may be formed into the end sections, to increase overall strength of the connector. Another embodiment has an internal tension member, which may be a loop of high-strength fiber, connecting the embedments.
