A cleat for mooring a watercraft at a thrown end of a line has a base surmounted by a body, the base being fastenable to a watercraft deck, the line having a rope and stopper formed by a transverse protuberance, the cleat having an engagement part adjoining the base and a funnel-shaped through-opening to an elongate slot in the body, the slot having a height allowing the longitudinal progression and transverse passage of the rope from the opening towards the interior of the body, the slot leading into a chamber having a minimum dimension greater than the minimum slot height, the maximum dimension of the chamber being less than the dimension of the protuberance forming the stopper so the stopper of a line passing transversely through the body can be blocked against a the body side face both with the rope in the slot and in the chamber.

There is disclosed an apparatus for mooring a structure and/or tensioning a mooring line. The apparatus comprises: a guide portion for guiding a portion of a first mooring line, and a lock arrangement, wherein the apparatus provides a mooring line path, the lock arrangement being provided on an opposite side of the mooring line path from the guide portion, at least when the lock arrangement is in an unlocked configuration. When in a locked configuration at least a portion of the lock arrangement is provided in the mooring path.

The present invention provides a string-type mooring system. A support frame is provided on a dock. Two free guide rollers are provided at vertical corresponding positions that are respectively below a cross arm of the support frame and above the dock. The two free guide rollers are respectively wound with a cable. One end of each cable is connected to a platform arm fixed on a platform, and the other end thereof is horizontally connected with one end of a spring. The other ends of the two springs are respectively connected with a hydraulic device. 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. The present invention can adjust the slow change of the vertical position of the platform caused by tidal fluctuation.

Methods and apparatus for monitoring windlass rotation are provided to determine the real time rate and length of rode release when anchoring a boat. The rotation can be monitored in real time using directional sound and/or electromagnetic radiation receivers and/or transmitter in a module attached to the windlass. Another windlass module can monitor windlass rotation using micro-electromechanical systems (MEMS) components such as accelerometers, magnetometers, gyroscopes, and/or inertial measurement units (IMU) to sense motion and/or position.

The invention relates to a buoy comprising a buoyant, plastic core component, and a plurality of detachable flotation components that support and surround the core component. The buoy is preferably more than 2.5 metres diameter, but the diameter of the core component is preferably less than or equal to 2.35 metres diameter. This facilitates transport in a single shipping container. A novel tie bar assembly and novel lifting/mooring mounts are also disclosed.

A mooring loop is operative to secure a movable device such as a ship in connection with a bollard or other fixed structure. The exemplary mooring loop includes a continuous rope segment that includes at least one coil or a plurality of coils. The rope segment defining the mooring loop includes an inner core surrounded by an outer jacket. A plurality of controlled failure points are included in the rope segment. The failure points enable the rope segment to permanently elongate in response to an applied tension force at a level above a working range, which elongation is visibly observable. The controlled failure point is defined between segmented ends of a severed inner core such that only the outer jacket is located at the controlled failure point.

An offshore water production facility to be located on a body of water includes a floating object, at least one wind turbine, a power generator that is coupled to the wind turbine and a water production system. The floating object includes a plurality of buoyancy assemblies that support at least one column on which a wind turbine is mounted. On the at least one column further a process equipment deck is mounted below an operating area of the wind turbine and above a water surface level. The water production system is arranged on the process equipment deck, and the water production system is configured for subsea well water-injection and includes an ultra-filtration unit and a membrane de-aeration unit for water to be injected.

The present invention provides for a method of marine construction. Said marine construction is based on an external perimeter and inner area and comprises seabed lying elements and floating elements. The marine construction of the present invention comprising fixed elements that are placed on the defined perimeter of said marine construction. Said fixed elements are lying on the seabed. And further comprising floating elements that are placed in the inner area the marine construction, defined by said external perimeter. The marine construction is capable of being deployed at a variety of distances from shore, at a differential nature of sea bed, and to be able to carry out different tasks and destinations, such as but not limited to airport, residency, army base, power station, port, marina, other infrastructures, etc. and any combination thereof.

Disclosed is an assembly for anchoring a submerged vehicle to a stationary object. The assembly includes a telescoping tube having a hollow inner tube and a hollow outer tube, each the inner tube and the outer tube having a proximal end and a distal end. The distal end of the inner tube slidably received within the outer tube through its proximal end. A snap button configured at the proximal end of the outer tube that can engage with a hole near the distal end of the inner tube for locking the movement of the inner tube within the outer tube. A rope having a first end and a second end, the first end of the rope attached to the inner tube near its proximal end. The second member passes through the eye of the spring hook and into the proximal end of the inner tube to form an anchoring loop. The second end of the rope exits the telescoping tube through the distal end of the outer tube and forms a boat hook loop.
