  • Patent number: 9115777
    Abstract: A self-retracting extension limiting device. It is designed to be attached between a first object and a second object, where the distance between the first and second objects is variable. The device exerts a restoring force tending to draw the two objects together. A first, relatively weak restoring force is exerted over a range of distance. Then, when the objects have been separated to a defined limit of travel, the device exerts a much greater restoring force. The invention includes overlapping and self-contained elements so that unwanted slack is minimized.

  • Patent number: 8967066
    Abstract: An apparatus and method for use on aquatic vessels for automatically retracting a docking line released from the vessel when undocking so that it is stored out of the water next to a fixed structure such as a piling, initiated with one simple manual operation; and extending the line when docking the vessel by engaging said line and attaching it to the vessel, also all with one simple manual operation. The means for generating the retraction forces acting on the docking line can be a spring-actuated reel mounted on the fixed structure, causing tension in a thin retrieving line attached to the docking line. Alternatively the forces can be generated by sets of weighted blocks and pulleys, or elastic cords. Use of the embodiments will avoid undocking stresses of using long boathooks to hang docking lines on pilings, and reaching them when docking; or throwing them.

  • Patent number: 8950350
    Abstract: A fabric shielding tube protects an elastic end portion of a stretchable segment of a mooring rode from abrasion, water, and marine life, without inhibiting extension of the stretchable segment. The ends of the tube are attached to the rode at the ends of the elastic end portion, with the tube extending beyond the elastic portion and folding back on itself in a rolling wall configuration. The tube thereby adapts to extension of the rode by partially unrolling the rolling wall. At its distal end, the tube is attached only to an outer braid of the rode by a means that does not inhibit extension of the braid or of an elastomeric core within the braid. The distal end attachment can be by sewing, or by interweaving of a strap such as a cable tie through the shield and the braid. The fabric shield can include nylon.

  • Publication number: 20150017849
    Abstract: A system and method for offshore loading of large cargo vessels, or motherships. The system includes a plurality of mooring stations, which may be mooring buoys, positioned in an offshore mooring field proximal an onshore cargo loading facility. A mothership is positioned within the mooring field and moored via bow and stern lines to two or more different mooring stations. Environmental data, including wind, wave, and current data, as well data regarding the physical characteristics of the mothership and movement (roll/pitch/heave) of the mothership are collected by remote transmitting and sensing devices. This data is processed by numerical analysis in a digital processor, namely a computer, to determine optimum mooring line length and tension, and mooring station locations, in order to minimize mother ship movement and create an optimum “lee” loading area adjacent the mothership. Cargo is transferred to the mothership by a trans-shipper moored to the mothership.

  • Patent number: 7978806
    Abstract: The Seafloor Power Station is one or more unmanned electric power generating Units (2) sending power to and operated from existing coastal sites by a manned facility (1) by connecting lines and hoses (3) delivering power to a grid by lines (4). Each Unit's hull (11) maintained in a vacuum, contains both nuclear steam and electricity generating systems. The hull functions as overpressure containment and as condenser in the event of a loss of coolant accident or other steam release. The Units operate submerged in very cold water, with depth set by remotely controlled vertical mooring systems, mounted on gravity mats (27). A Unit must be surfaced by its mooring system to refuel the reactor, an action both conspicuous and public, enabling international oversight of the fuel disposition.

  • Publication number: 20100024706
    Abstract: A system and method for configuring and supporting mooring lines deployed on offshore structures, e.g. Spar-type platform, are provided with recessed portions that are located around the splash/ice zones for “cutting” through waves. An offshore structure may be provided with a chain tensioning mechanism that applies a desired tension to a hull chain and mooring line during mooring. Upon mooring the offshore structure, a chain lock mechanism maintains the tension in the hull chain and mooring line, while the chain tensioning mechanism releases a portion of the hull chain which is to be stored in a chain housing which is fully submerged underwater. This way, the recessed portions of the offshore structure around the splash/ice zones would be substantially free of the hull chains. Additionally, a disconnect mechanism may be provided to allow quick and safe disconnection of the offshore structure from the mooring position.
