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： Disclosed is buoyant wave energy capture device, adapted to float adjacent to an upper surface of a body of water over which waves pass, and adapted to capture a portion of the radiated waves created by its own rising and falling in response to incident and/or passing environmental waves. A power take off mechanism combined with the disclosed wave energy capture device may be tuned to a specific wave frequency, and thereby optimally extract energy from a motion of a single frequency, even the wave energy capture device may be excited and/or energized by waves of any of a relatively broad range of frequencies, thereby increasing the power-generation and cost efficiencies of such devices relative to wave energy conversion devices of the prior art.

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： 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.

摘要： In a general aspect, a method is presented for manufacturing support structures for offshore wind turbines. In some implementations, the method includes constructing a plurality of modular sections that assemble to define the support structure. One or more of the plurality of modular sections are configured to anchor to an underwater floor. At least one of the plurality of modular sections is constructed by operations that include forming a wall along a perimeter to bound a volume, filling the volume with a castable material, and hardening the castable material. In some instances, forming the wall includes depositing layers of printable material successively on top of each other. The method also includes joining the plurality of modular sections to assemble the support structure.

摘要： A mooring line that provides substantially constant force, also referred to a mooring line that is always soft, allows the orbital motion of a moored turbine structure under varying wave conditions and is suitable for storm conditions when the turbine is not operating. A mooring line with substantially constant force does not create surge acceleration from heave acceleration and does not cause the turbine structure to be pulled through the water relative to orbital velocity.
