Abstract: The present invention provides a long-term mooring device. A support frame is provided on a dock. The dock is provided with a free guide roller. The free guide roller is wound with a cable. An upper end of the cable is horizontally connected to a spring fixed on a lower side of a cross arm of the support frame, through a free guide roller provided on the lower side of the cross arm of the support frame (corresponding to the free guide roller on the dock). The middle of the cable penetrates through an inertial induction self-locking connection joint fixed on an end of a platform arm. The platform arm is fixed on a platform. The present invention provides an omnidirectional restoring force for the moored platform through the elastic deformation of the springs to control the movement response of the platform within a certain range.

Abstract: A cable supporting device can suppress a coil spring from protruding toward an inner circumferential side of a tubular portion of a main body, and can apply, to a nut member, a rotational force in a direction toward a stopper. The cable supporting device includes: a main body including a tubular portion in which a through hole is formed and on which an external thread is formed; a nut member; a stopper arranged on one side in the first direction with respect to the external thread and opposed to the nut member; and a coil spring applying, to the nut member, a rotational force in a direction approaching the stopper. An engagement portion that engages a first end portion of the coil spring is formed in the nut member, and an insertion groove is formed on the outer circumferential surface of the tubular portion.

Abstract: An anchoring device may be arranged above or below a body of water and may secure or anchor watercraft to at least one vertical object and/or horizontally-positioned object. The anchoring device may provide a clamping mechanism that may secure the anchoring device to the at least one vertical object and/or horizontally-positioned object. The anchoring device may be integrated or fixed to watercraft, such as at a seat pedestal. The anchoring device also may be used without being integrated or fixed to watercraft.

Abstract: A shock absorbing docking spacer for connecting a vessel to a mooring structure and which includes first and second sections relatively telescopically movable longitudinally relative to one another so as to define a variable effective overall length for the docking spacer and wherein one section contains an airtight air bag and the air bag is connected to the other section such that as the first and second sections move relatively inwardly relative to one another the air bag provides a buffer for absorbing impact forces between the first and second sections brought about by ambient conditions.

Abstract: An apparatus is described for fixing floating bodies (1), in particular boats, to a landing body (2) with at least two holding booms (5) which are fixed to respective moorrings (4) by fittings (3) functioning as coupling elements, in each case at one end on the floating body (1) and at the other end on the landing body (2). In order to create advantageous conditions, it is proposed that at least one of the holding booms (5) be fixed, at least at one end, to the respective moorrings by the fitting (3) functioning as a coupling element so as to be rotationally fixed or rotationally resilient about an at least approximately vertical axis (7) with an adjustable and fixable angular offset (?).

Abstract: A docking mechanism comprises first and second units, operative to firmly attach and release a watercraft such as a ferry boat to a dock. This action can be produced by actuators that may be hydraulic or pneumatic actuators, or by other means such as manually actuated levers, electric motors or solenoids. A moveable locking piston acts to push locking cylinders or other locking members such as movable links against watercraft lock channels mounted upon the watercrafts. The apparatus results in very firm coupling of a watercraft to the dock, beneficially permitting ferry boats to load and unload cargo without keeping their engines running which wastes fuel and pollutes the environment. The lock channels on the watercraft are however configured to permit relative vertical motion between the watercraft and the latching assembly to account for water level changes and yet maintain very firm coupling of the watercraft to the dock.

Abstract: A boat docking unit for small boats secures a boat to a dock structure without use of ropes, anchors or fenders. The unit has a pair of docking arms each having an elongated tubular housing, a telescoping member capable of telescoping movement within the housing. A pair of compression springs mounted in the housing in contact with the telescoping member dampens the wave force so as to restrict yaw of the boat docked at the pier. The docking arms pivotally secure the boat to the dock structure allowing a limited pitch motion of the boat.

Abstract: A mooring device including two telescoping tubes, a pair of ropes for securing a boat to a dock or piling, and a spring biasing the ropes and/or tubes with respect to one another to adjust to changes in waves and/or tides, while maintaining the boat at a safe distance from the dock or piling.

Abstract: A mooring device for mooring a boat at a selected nominal distance from a mooring point, with the boat being movable resiliently toward and away from the mooring point while biased into the selected nominal distance. First and second members are engaged with one another for movement relative to one another in longitudinal directions along the mooring device, and are resiliently biased, by a resilient biasing arrangement, into a nominal length which establishes the nominal distance. A band couples the first and second members for selected relative movement and enables ready adjustment of the length of the mooring device to any desired length within a range of length. A locking arrangement secures the band against movement to retain the first and second members at the selected length.

Abstract: A system is provided for rigidly attaching a supply ship to a receiving ship to facilitate efficient transport of materials there-between even when the vessels are subject to heavy seas and weather. A telescoping truss assembly is provided on the first ship, and has a distal end configured to mate with a receptacle assembly on the second ship. Cables are disposed within the truss and are used to draw the truss and receptacle assemblies into engagement with each other. Once the assemblies are engaged, a hydraulic system is used to draw the two ships together, rigidifying the truss assembly and fixing the two ships in a “catamaran” arrangement. Subsequent transfers of materials between the ships can be carried out without the need to compensate for the relative dynamic vertical and horizontal displacements between the ships due to wind and waves.

Abstract: A mooring robot releasably fastening a first moveable object (S) to a second nearby object. The first moveable object (S) moves in response to the application of external forces to the object (S). The robot operates to restore the first object (S) to a predetermined operating position. With the particular reference to the mooring of a vessel (S), the mooring robot has attractive attachment element(s) fixable to a ship's hull and includes a movement unit with active three-degree-of-freedom translation, for controlling the position of the attachment element(s). The movement includes a restorative means associated with each of the two degrees of translation freedom in the horizontal plane which provide a restorative force acting to return the attachment element(s) to the predetermined operating system.

Abstract: This invention relates to a shock absorbing docking spacer to space a tethered boat from dockside. It comprises an elongated body having two cylindrical sections moveable longitudinally of each other to define spacer length with one of said cylindrical sections being connectable to a boat and the other of said cylindrical sections being connectable to a dock. A resilient cord is connected at one of its ends to one of said cylindrical sections and at the other of its ends to the other of said cylindrical sections to be tensioned as the cylindrical sections move longitudinally of each other due to shock forces in use to reduce spacer length. The cord cord has a resilience as aforesaid to absorb shock forces on the boat that reduce the spacer length in use, and to reassert itself and restore spacer length when shock forces are removed.
