摘要： An aquatic wind power generation system includes: a hull that navigates on water; a power generation system that includes a kite connected to the hull via a tether, and repeats between a power generation mode, in which wind power is generated by an unwinding operation of the tether due to flight of the kite, and retraction mode, in which the tether is retracted by a winding operation of the tether; and a controller that performs control to direct a bow of the hull in a leeward direction in the retraction mode.

摘要： A method of repositioning a floating offshore wind turbine located at a current offshore position and having rotor blades rotating in a rotor blade plane includes: measuring a first value of a variability of a load related to a first location at the wind turbine; measuring a second value of a variability of a load related to a second location at the wind turbine; comparing the first value with the second value; and moving the wind turbine along a direction depending on the comparison and in particular further depending on the first location relative to the second location.

摘要： An assembly for producing offshore electricity having
a wind turbine,
a monopile extending along a vertical direction and fully supporting the wind turbine, the monopile penetrating in a seabed, and
a subsea jacket comprising:
a structure anchored in the seabed and surrounding the monopile around the vertical direction, and
a central guide fixed on the structure and surrounding the monopile around the vertical direction while being vertically free with respect to the monopile, the structure being adapted for resisting horizontal loads applied by the monopile on the central guide due to bending movements of the monopile.-

摘要： An apparatus for yawing a turbine into the wind while reducing time-averaged loads has weight-balanced, aerodynamic fairings that cover structural elements of an offshore wind turbine. The aerodynamic fairings provide a rudder effect while a weight-balancing apparatus counters aeroelastic instability and buffers the effects of side gusts.

摘要： A gravity based foundation for an offshore installation includes a caisson of concrete and a hollow shaft. The caisson has a bottom slab, a roof and a side wall extending between the bottom slab and the roof. The roof having a passage for the shaft into the caisson. The shaft support has embedded tensioning bars vertically projecting from the upper side of the shaft support. The shaft is mounted on the shaft support by the tensioning bars. A method of manufacturing includes providing a concrete bottom slab, arranging a full-length formwork onto the bottom slab, arranging a slip formwork onto the bottom slab, providing the tensioning bars and mounting the tensioning bars in a fixed position to the full-length formwork, and concrete pouring of the sidewall and shaft support while raising the slip formwork.

摘要： Delivery of a high volume of floating systems for wind turbines can make floating wind economic. The delivery can involve the standard design of sections, such as “tubes” or “cans,” comprising a rolled plate and ring stiffeners. The delivery can then involve the transportation of the sections in block to an assembly site that is closer to the planned installation point. The sections are used to manufacture floating vessels, such as semi-submersibles, buoyant towers, and/or spars, at the assembly site, which can include a barge with cranes. For semi-submersibles, the delivery can then involve the installation of the Tower, the nacelle, and blades using the barge cranes. Alternatively, for spars or buoyant towers, the nacelle and blades can be installed at an off-shore location using a platform, such as a standard jack-up vessel or a crane jacket.

摘要： A portal frame platform comprises at least three elongate tubular legs extending vertically downward from a top above the waterline to the seabed without horizontal or diagonal bracing members in-between, and a horizontal deck with at least three circular sleeves concentrically coupled to the top of the legs supporting a wind turbine in an in-service configuration. The portal frame platform supporting the wind turbine has an installation configuration with two barges connected to opposite sides of the deck, and the legs extending vertically upward from a bottom above the waterline through the circular sleeves. A construction method includes twelve-steps for quayside assembling, sea-towing and self-installing the portal frame platform with the wind turbine and foundation piles wherein the portable frame platform is converted from the installation configuration to the in-service configuration by lowering the legs through the circular sleeves using wire and winch systems on the two barges.
