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 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.

A disconnectable mooring system for offshore semi-submersible floating structures. A disconnectable buoy has a number of mooring lines which include a buoy chain between the mooring chain and the buoy. The mooring chain and the buoy chain are connected via a three way mooring connector, with the third connection configured to pull the mooring connector to a mooring point on the structure. In a first configuration the buoy is disconnected and supports the mooring chains for recovery at shallow depths to be pulled in. In a second configuration, the mooring lines are pulled in via the mooring connectors thereby providing a spread mooring to the structure with the buoy chain left as a catenary between the buoy and mooring point.

A system for offshore production of LNG from an FLNG vessel includes a floating LNG vessel including a hull and a deck, a topsides hydrocarbon processing facility installed at or above the deck of the hull of the FLNG vessel, a FLNG vessel cargo containment system comprising one or more insulated FLNG vessel cryogenic storage tanks installed within the hull of the FLNG vessel, a dynamic positioning control system operatively associated with a system of thrusters onboard the FLNG vessel where the dynamic positioning control system maintains the FLNG vessel at a desired heading around a station keeping point during LNG cargo offloading operations, and a computer processor for receiving a set of real-time monitored environmental data.

A bearing system including a wheel assembly transmitting load to a damping assembly, wherein the wheel assembly is configured to rotate angularly relative to the damping assembly.

A sea hose load analyzer system is disclosed. The sea hose load analyzer system also includes a transceiver interface. The sea hose load analyzer system also includes a memory storage. The sea hose load analyzer system also includes circuitry may include one or more processors configured to: receive load information of one or more sea hoses as node unit data via the transceiver interface, store the load information in the memory storage, and monitor additional node unit data via the transceiver interface.

One general aspect includes a buoy position analyzer system. The buoy position analyzer system also includes a transceiver interface. The buoy position analyzer system also includes a memory storage. The buoy position analyzer system also includes circuitry may include one or more processors configured to: receive node unit data via the transceiver interface, generate an operational movement envelope for a buoy based on the received node data, store the operational movement envelope in the memory storage, and monitor additional node unit data via the transceiver interface.

The invention relates to a system (2), having: a buoyant buoy (4), and a floating hose (6) which has a plurality of buoyant hose segments (8) which are coupled in series. The buoy (4) has a liquid outlet connection (12) which is connected to the floating hose (6), so that the floating hose (6) is arranged in a geometrical arrangement with respect to the buoy (4). A plurality of node units (18) are fastened in a distributed manner to the floating hose (6) and the buoy (4). Each node unit (18) is designed to establish, by means of an associated radio unit, a respective radio link (22, 24, 26, 28) to each of at least two of the further radio units of the respective node units (18, 42, 44, 46, 48), so that a radio network (30) is created. Each node unit (18) is designed to determine a relative distance (32, 34, 36, 38) from each further node unit (18) on the basis of the respective radio link.

A system for temporarily connecting an underwater station arranged on the bed of a body of water and a surface facility has an elongated conducting member with one end connected to the underwater station and one free end selectively and temporarily connectable to the surface facility; a marker buoy; and a cable connected to the free end of the elongated conducting member and to the marker buoy to quickly recover the free end of the elongated conductor element when it is necessary to connect the underwater station via the elongated conducting member to the surface facility.
