A mooring assembly for a vessel includes a turret with a lower receptacle cone receiving a buoy, mooring lines attached to the buoy, and risers. The buoy includes a plurality of pivot legs positioned on a lower part of the buoy, wherein the legs are pivotably connected to the buoy through a horizontally extending pivot axis to pivot in a radial plane with respect to the buoy between a first position with the buoy in the cone of the turret, in which the legs extend mainly vertically downwards and engage an inner surface of the cone, and a second position with the buoy outside of the cone, in which the legs extend mainly horizontally outwards. The lines are attached to the legs and each leg has such a length that in the first position its end is located at a level below the lowermost end of the cone.

A system for fluid transfer is disclosed and includes a floatable buoy, an underwater hose, a plurality of underwater node units and circuitry. The underwater hose has a first end coupled to the floatable buoy and a second end. The plurality of underwater node units distributed along the length of the underwater hose and configured to generate positioning signals. The circuitry is configured to determine a relative distance between each of the plurality of undersea node units based on the generated positioning signals to generate a plurality of relative distances.

A system (100) and method for mooring and anchoring of floating solar panels (150) on water surface is disclosed. The system (100) has a floater unit (154) for securing the solar panels (150), The floater unit (154) has securing means (152) along its circumference. Buoys (122, 124, 126, 128) are floated on the surface of the water body such that each buoy is anchored to at least one anchor (142, 144, 146, 148) at a floor of the water body. Main mooring lines (112, 114, 116, 118) are connected to the buoys (122, 124, 126, 128). A parabolic curve is formed by connecting one end of the adjacent main mooring lines to the same buoy. A plurality of connecting lines (162, 164, 166, 168) are used for connecting each main mooring line (112, 114, 116, 118) with the securing means (152) at corresponding side of the floater unit (154).

Aspects of the disclosure pertain to single point mooring systems and method used in relation to single point mooring systems wherein, the system divides the restoring weight for the mooring system in two and removes hinges and swivel joints from the gravitational load path suspending the restoring weight.

A modular floating platform system includes a detachable floating buoy providing a body tethered to a seafloor with a plurality of mooring lines and coupled to a subsea production system via one or more communication lines, and a plurality of floating surface facilities, each floating surface facility providing a standardized bottom interface matable with the detachable floating buoy. A latching mechanism individually couples each floating surface facility to the detachable floating buoy when each floating surface facility is individually mated to the detachable floating buoy. One or more communication couplings place each floating surface facility in communication with the subsea production system via the one or more communication lines when each floating surface facility is individually mated to the detachable floating buoy.

A subsea tubular system comprises extended sections of a first material and interposed sections of a second, different material that aids in damping vibration resulting from subsea dynamic conditions such as current. The vibration damping sections may make up a portion of the overall system significantly less than the sections of the first material. The number, length, and positions of the vibration damping sections may be selected based on factors such as the diameter, overall length, profile, and so forth. The system may be used as a riser or other conduit for the production of minerals such as oil and gas.
