摘要： A mooring connector assembly (3) has a body (10) arranged to be pivotally mounted to a structure (1), such as a tethered buoy, to be moored for movement about a pivot axis. At least a part of the body extends below the pivot axis when so mounted and oriented for use. A line stopper (17) is mounted to the part of the body which extends below the pivot axis in use and is operative to retain a mooring line (2) relative to the body. The body is configured to receive a tensioner (20) for tensioning a mooring line (2) retained by the stopper such that the tensioner urges the line at a point which is below the pivot axis when the body is oriented for use. The body may be an elongate tube (10) pivotally connected to a structure to be moored (1) at one end and fitting with a chain stopper (17) at the opposite end. The tube is configured to receive a chain tensioner (20) between the chain stopper (17) and pivot axis.

摘要： The invention relates to an improved, in particular simpler, lighter, mechanically more stable and operationally more reliable offshore wind power plant (100) that can float. By means of a cable (110) constructed as a combination of a power line that is held at least virtually without loading and a holding cable that absorbs all the mechanical forces that occur for holding the wind power plant on a single fixed-location anchoring point (111), said power plant can be connected to the anchoring point such that the power plant can move with six degrees of freedom. A coupling (112) is arranged at a single connecting point (118) between the cable and the wind power plant and, to make an electrical connection, is constructed with a sliding coupling and, for mechanical transmission of force, is constructed with a swivel coupling. The wind power plant has a supporting unit (101) constructed as a semi-submersible having ballast units (102) and buoyancy units (103), in particular a floating unit, and a supporting mast (104) which is firmly connected to the supporting unit and has a machine gondola (105) fixedly arranged on the latter and having at least one rotor (106) and at least one electric generator. The highest possible horizontal distance is formed between the connecting point and a substantially vertical plane of rotation of the rotor.

摘要： The present invention provides a buoyant system and method for a hydrocarbon offshore floating platform to be coupled and decoupled from a subsea buoyant extension with risers slidably coupled thereto. The buoyant system can allow rigid risers to be coupled and decoupled and alternatively move between a first elevation below the offshore floating platform, such as at the buoyant extension, and a higher second elevation at the offshore floating platform independent of a spool piece, arch support, and flexible joint for the risers. The buoyant system can reduce riser stress by reducing bending required for the riser to form a catenary or other curved shape even as a rigid riser.

摘要： An observation system and determination method for the re-suspension quantity of submarine sediments by deep-sea internal waves. The observation system comprises a submarine observation platform, a mooring rope, and an anchor mooring counterweight. Acoustic release transponder, a single-point current meter, a turbidity meter, a high-precision temperature and salinity detector, and a sediment catcher are mounted on the submarine observation platform. A main floating body and auxiliary floating bodies are arranged on the mooring rope, wherein the main floating body is located in the middle of the mooring rope and is equipped with acoustic Doppler current profilers, and the auxiliary floating bodies are equipped with turbidity meters and high-precision temperature and salinity detectors. The anchor mooring counterweight is a gravity anchor provided with a square clamping groove and a fixed ring.

摘要： Disclosed is a fairlead for guiding an anchoring element of an offshore structure, such as a floating structure, at an anchoring point, of the type having a guide for the anchoring element and a lock holding the anchoring element in position, having a locking jaw including two locking jaw elements that are movable by a maneuvering unit actuated by a controller, between a closed position preventing the anchoring element from moving in translation and an open position releasing the anchoring element. The controller is of the impulse-type, and the maneuvering unit includes a pawl that defines successive stable open and closed positions of the jaw-forming unit.

摘要： An underwater anchoring assembly and method for supporting a pipe with the underwater anchoring assembly are disclosed. The underwater anchoring assembly includes a first pile, a second pile, a first cross-member coupled with the first and second piles, and a second cross-member rotatably coupled with the first pile at a first end portion thereof, and detachably coupled with the second pile at a second end portion thereof. The method includes advancing the underwater anchoring assembly into the ground in an unactuated state, positioning the first cross-member above the pipe, rotating the second cross-member about the first pile such that the pipe is interposed between the first and second cross-members, and coupling the second end portion of the second cross-member with the second pile via a fastening mechanism to thereby support the pipe.

摘要： Mooring chains used in offshore environments are typically formed from carbon steels due to their wear and fatigue resistance properties. Although carbon steels may exhibit robust mechanical properties, they are susceptible to corrosion, which can shorten the usable working lifetime of mooring chains, particularly in a seawater environment. Austenitic steels comprising high percentages of manganese may have comparable mechanical properties to the carbon steels commonly used in mooring chains, yet exhibit less susceptibility to corrosion. Austenitic steels suitable for use in mooring chains and other structures in contact with or exposed to a seawater environment may comprise: 0.4-0.8 wt. % C, 12-25 wt. % Mn, 4-15 wt. % Cr, a non-zero amount of Si
