The systems and methods disclosed herein provide inventive means for repurposing wind turbine blades. In an embodiment, a derivative of a decommissioned wind turbine blade may be positioned and anchored for use in soil retention installations (e.g., slope stabilization, land building, etc.). In another embodiment, a derivative of a decommissioned wind turbine blade may be implemented in infrastructure installations (e.g., bridge decking). In yet another embodiment, a derivative of a decommissioned wind turbine blade may be positioned and anchored to mitigate snow drifts (e.g., as a snow break). Additional uses of wind turbine blades are considered and disclosed herein.

The present disclosure relates to an offshore substructure supported by a template-integrated suction foundation and an installation method thereof, more particularly to an offshore substructure installed by pre-piling construction including: a suction foundation having a plurality of suction piles pre-inserted into the seabed by suction, joint sockets connected to each head part of the suction piles, and connecting members connecting spaces between the joint sockets; and a substructure connected onto an upper part of a suction foundation pre-piled, wherein an insertion socket connected to a lower part of the substructure is inserted into the joint socket, and the suction foundation and the substructure are connected by grouting a space between the insertion socket and the joint socket.

A foundation (1) for a structure (7) comprising a body (8) having a lateral surface (11) and a distal end (10) for insertion into a soil (2). At least a region of the lateral surface (11) forms a first electrode. One or more second electrodes (9) are provided on the body (8) and are flush with or sit proud of the lateral surface (11). Each second electrode (9) extends transversely around the lateral surface (11) and is electrically insulated therefrom by an insulating strip (12) provided between the respective second electrode and the lateral surface. During installation, a voltage may be applied across the electrodes for inducing an electroosmosis effect to reduce installation resistance.

A clamper plate for securing a tower having a flange to a pedestal having an embedded first bolt and second bolt is disclosed. The clamper plate includes a first surface coming into contact with the flange and a second surface coming into contact with the pedestal. The clamper plate also includes a first through-hole for receiving the first bolt therethrough and a second through-hole for receiving the second bolt therethrough. During installation the clamper plate is placed over the flange and secured to the pedestal through the first bolt and second bolt.

The invention relates to a foundation for a wind turbine, wherein the foundation comprises substantially prefabricated elements, preferably made of reinforced concrete, with a first, vertically extending base-like portion, on which a tower of the wind turbine can be arranged, and a second substantially horizontally extending portion as foundation body, which is in contact with the ground. The first portion is arranged above the second portion and has at least one closed, preferably sleeve-shaped, base element, which is annular or polygonal, and the second portion is formed from at least two horizontal elements, which each have at least one base portion. The at least one base element of the first portion and the base portion of the horizontal element of the second portion have substantially vertical apertures, which are mounted in line with one another and in which substantially vertical bracing elements, preferably threaded rods, are arranged. The at least one base element of the first portion and the at least two horizontal elements of the second portion are preloaded against one another by the substantially vertical preloading elements. No further fastening means, in particular horizontal fastening means, are necessary for dissipation of the loads from the wind turbine.

A foundation for a wind mill includes a circular or polygonal pedestal for supporting a wind mill tower and a plurality of ribs radiating radially outwardly from the pedestal, wherein the pedestal is divided into a plurality of circumferential sections, wherein a circumferential section and a rib are each integrally formed with one another as a precast concrete element, wherein the precast concrete elements are made from reinforced concrete including a first reinforcement structure, in particular reinforcement bars, embedded into the precast concrete elements, a second reinforcement structure is provided, which holds the precast concrete elements together and which is coupled to the first reinforcement structure.

A retrofit reinforcing structure addition and method for an existing gravity spread foundation for a wind turbine or the like having a central pedestal and a spread section is provided. The retrofit structure addition includes a collar formed around the pedestal of the spread foundation. The collar is formed by a shape sustaining member, such as a CMP, placed around the pedestal to define an annular ring between the CMP and the pedestal that is filled with cementitious material. Radial bolts extend horizontally through the collar and into the side of the pedestal. Soil and/or rock anchor bolts extend vertically through the collar, the spread portion of the foundation and into the underlying soil and/or rock substrate. The radial and anchor bolts are post-tensioned to ensure that the cementitious material of the collar remains in compression and the bolts are always in static tension, strengthening the original gravity spread foundation and extending the fatigue life thereof.

A foundation for an offshore structure, more particularly an offshore wind turbine structure, comprising: at least one tower-like foundation structure with a circumferential foundation wall extending in the longitudinal direction, the foundation wall being delimited at the lower end by a lower-end end face, the foundation wall being formed from a mineral construction material; and at least one binding element, which is formed from a metal material and is arranged on the lower-end end face, the length of the binding element from the lower-end end face to a lower end of the binding element being at least 0.5 m.

A method for constructing a solar cell farm includes steps of: (1) installing a plurality of reinforced concrete piles on a latticed divided surface of a ground or a water level of the foreshore in a solar cell panel installation area; (2) constructing a lattice-type truss by connecting a plurality of steel beams in a transverse direction on the concrete piles and a plurality of rails on the steel beams in a longitudinal direction on the steel beams; (3) installing a solar cell panel by varying the slope of the panel by varying the length of a length-variable connection means between the plurality of rails of the truss and 4 axes of the left, right, upper and lower sides of the solar cell panel; and (4) constructing a rail for driving the track vehicle between the rails mounted on the transverse steel beams of the truss.

A foundation for a wind turbine tower includes a base slab, a pedestal provided on the base slab, the pedestal including attachment means for attaching the wind turbine tower; and a plurality of radial walls extending from the pedestal towards an outer edge of the base slab, wherein at least one of the base slab, the pedestal and at least one of the plurality of radial walls is made of or includes fiber reinforced concrete.
