The present invention provides a mooring device capable of providing an omnidirectional restoring force. 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. A rotary damper is provided in the middle of a longitudinal portion of the support frame that is perpendicular to the dock. The two free guide rollers are respectively wound with a cable. The cable is fixed to a platform arm, and the platform arm is connected to a platform. An end of each cable is connected to a spring, and the other end of the spring is connected to a chain wound on a sprocket of the rotary damper.

An anchor rope system for an offshore device for fixing an offshore device to a subsea floor. The anchor rope system includes at least one anchor rope surrounded by at least one sheathing. The anchor rope system includes at least one condition sensor formed by at least one fiber optic cable.

An underwater vehicle includes a hull extending along a main longitudinal axis and at least one first pincer member disposed towards a forward end of the hull, characterized in that it further includes a second pincer member disposed towards an aft end of the hull, which is an opposite end to the forward end, the first and second pincer members being disposed respectively on a first lateral part and a second lateral part of the hull, on opposite sides of the main longitudinal axis, and being configured to take an open position or a closed position, and a detection member and a guide member which are respectively configured to detect cables and in order for the first and second pincer members to come respectively into engagement with one of the respective cables.

The disclosed invention relates to a connecting system for connecting a mooring line to a body comprising a first part being attached to the mooring line and connected with a pin having two ends, to a second part being attached to the body and having an arrangement for guiding the pin into a hang-off structure in the second part where the hang-off structure substantially comprises at least one hook. The system is characterized by a connecting structure for a temporary pulling means mounted on the first part in transverse direction to its longitudinal axis and eccentrically to an axial center of gravity of the first part. The invention relates also to a method regarding the application of the system.

A wave energy thermal storage type seawater thermoelectric power generation device which comprises a buoy-type energy capture system, a platform system and a mooring system. A whole friction liquid heating, thermal storage and power generation device is arranged inside a platform, which improves the adaptability of the whole system to the external environment. A flywheel and liquid friction heating method is adopted to generate heat more efficiently. Inner ratchets and pawls are used to control the movement of a flywheel so that the flywheel always rotates in one direction, and when the rotating speed of the flywheel exceeds that of the inner ratchets, the external wave energy cannot be transferred to the flywheel through the movement of the inner ratchets so as to limit the upper limit of the rotating speed of the flywheel and protect the safety of the flywheel system.

The invention concerns the field of marine ropes, and more specifically a marine rope (1) comprising a plurality of cores (2; 2a, 2b), an individual coating (3) around each core (2; 2a, 2b), and a permeable protective sheath (4) around the plurality of cores (2; 2a, 2b). Each core (2; 2a, 2b) comprises a fiber strand or braid and each individual coating (3) is watertight and has a melting temperature lower than that of the corresponding core and an elongation at break greater than that of the corresponding core.

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.

A line hauler on a fish tender vessel is mounted to a port or starboard quarter location of a deck of the vessel. A loop of floating line is wrapped around the line hauler, extends toward the bow of the vessel to a pulley mounted on a respective port or starboard side, then extends down to the sea, then extends on the surface of the sea adjacent the respective port or starboard side to at least the location where the line hauler is mounted to the deck, and then extends from the surface of the sea back to the line hauler. The loop of line moves in a circle when the line hauler pulls on the line. Lead lines are connected to the line. Fishing vessels attached to the lead lines are pulled alongside the respective port or starboard side of the vessel when the line hauler pulls the line.

There is disclosed an apparatus (100) for mooring a structure and/or tensioning a mooring line. The apparatus (100) comprises: a guide portion (105) for guiding a portion of a first mooring line (110), and a lock arrangement (115), wherein the apparatus (100) provides a mooring line path (120), the lock arrangement (115) being provided on an opposite side of the mooring line path (120) from the guide portion (105), at least when the lock arrangement (115) is in an unlocked configuration. When in a locked configuration at least a portion of the lock arrangement (115) is provided in the mooring path (120).

A mixed rope used for oceanographic buoy mooring system, comprises mixed core rope of metal and fiber and cover rope, wherein, the mixed core rope of metal and fiber comprises metal coil spring and fiber supporting core inside the metal coil spring; the cover rope is woven of several number of twisted strand; the mass content of the mixed core rope of metal and fiber is not greater than 20% of the mass of mixed rope, the mass content of the cover rope is not less than 80% of the mass of the mixed rope. Mixed rope used for oceanographic mooring system disclosed in present embodiments has small linear density and high fracture strength, may be used as data communication channel from under-water sensor to the over-water receiver, being soft, light and easy to deploy, the mixed rope can be used as the upper part of the oceanographic buoy mooring system with prospective application.
