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.

A yoke plate assembly for mooring a floating object in a body of water by a pair mooring lines, includes an assembly plate mechanically coupling to an anchor body, an elongated yoke plate with a center thereof pivotally connected to the assembly plate by an articulation, a first lever arm having a first proximal end connected by a first coupler to a first end of the elongated yoke plate, a second lever arm having a second proximal end connected by a second coupler to a second end of the elongated yoke plate longitudinally opposite the first end. The first lever arm at a first distal end thereof is connectable by a first distal joint to one of the pair of mooring lines, and the second lever arm at a second distal end thereof is connectable by a second distal joint to the other of the pair of mooring lines.

A foundation pier bracket system provides attachment of a pier shaft with a building or structure foundation such that the system provides securement to competent strata or soil below. The system can include a reinforcing sleeve and a bracket assembly. The bracket assembly can include a shaft receiving portion and a seat portion. The shaft receiving portion can define an aperture that is sized and shaped to receive a portion of the reinforcing sleeve therein. The seat portion can include a plurality of protruding members that protrude upwardly therefrom. The plurality of protruding members can be arranged such that they restrain lateral movement of a beam along the seat portion in at least one axis. The reinforcing sleeve can include a locking wedge that secures the reinforcing sleeve to the bracket assembly. A method of supporting a foundation of a building is also provided.

A measuring device and method for horizontal dynamic impedance of specified foundation depth based on differential response analysis of pulse excitation. The measuring method is realized based on the measuring device. Two rigid piles with different lengths are embedded into different foundation depths. Motion characteristics of the two rigid piles in the process of collision impact with the outside are different under the same pulse excitation. Dynamic impedance of specified foundation depth is deduced from the formula according to the differential response. Single-degree-of-freedom oscillators are arranged on the pile heads of the two piles, and strain gauges are arranged on the bottoms of the single-degree-of-freedom oscillators to obtain stress states of the single-degree-of-freedom oscillators, thereby calculating the relative displacements of the single-degree-of-freedom oscillators. This is simple in structure, reliable in measurement and convenient in data collection and processing.

Seawalls and methods for making seawalls are disclosed. A seawall may include a concrete footing, with a first plurality of anchorages disposed in the concrete footing. A plurality of precast concrete tee beams may include single-tee beams and/or double-tee beams. Flanges of the tee beams may be positioned to form seaward and landward faces of the wall, and stems of the tee beams may be coupled to the footing between the seaward and landward faces. A second plurality of anchorages may be disposed at tops of the stems. Elongate steel components extend through the stems, and are tensioned between the first plurality of anchorages and the second plurality of anchorages. Interior fill may be disposed between the seaward and landward faces. One or more wave deflectors may be disposed above the tee beams.
