Example embodiments relate to apparatuses, systems, and methods for securing an offshore platform to a bottom of a body of water comprising a shear assembly and a sleeve assembly. The shear assembly is operable to secure to the offshore platform at a first end and having a first connector portion at a second end. The sleeve assembly comprises a sleeve body forming an interior opening, the interior opening operable to receive at least a pile. The sleeve assembly further comprises a second connector portion secured to the sleeve body, the second connector portion securable to and un-securable from the first connector portion of the shear assembly.

A tower for a wind turbine may include an upper tower portion and a lower tower portion. The upper tower portion may include a tubular tower, and the lower tower portion may include a lattice tower. To improve ergonomics and work safety and make it possible to obtain a structural design with optimized forces, the lower tower portion may include a central tube positioned centrally within the lattice tower. Further, the central tube may have a smaller diameter, at least in certain portions, than at least part of the tubular tower of the upper tower portion. The tower may also include a transition piece between the upper tower portion and the lower tower portion. The transition piece may join the tubular tower of the upper tower portion and the central tube of the lower tower portion.

The present disclosure describes a base structural building module employing a core structural member having an array of upwardly and outwardly and downwardly and outwardly extending braces or arms extending therefrom. Tubular cans are mounted at the ends of each of the upper and lower arms to receive piles. One upper arm is aligned and paired with one lower arm and the pair's respective cans are aligned about their can axis. The modules employ flexible design by varying the lengths of the arms and their respective inclination or declination angles. Modules can be stacked one on top of another (and secured) to form multi-tiered structural building jackets for building vertical structures such as, for example, oil and gas platforms used onshore or offshore as well as other structures. Each tier can also comprise multiple modules joined laterally together to provide a wide variety of potential template configurations and building applications.

Provided is a submersible offshore platform configured to be installed at a sea floor installation site and a method of installing the offshore platform. The offshore platform may include: a primary node and a primary column disposed thereon; a plurality of support nodes; a plurality of pontoon sections, each of the plurality of pontoon sections configured to connect the plurality of support nodes to the primary node or to each other; and a plurality of buoyant modules, wherein each of the plurality of buoyant modules is detachably connected to a respective support node, wherein the plurality of buoyant modules are removable from the plurality of support nodes after the offshore platform is submerged and installed at the sea floor installation site. The removed buoyant modules may be reused for installation of other offshore platforms.

An offshore wind turbine installation comprising a wind turbine on a support structure. A concrete-cast transition piece is provided in between the tower of the wind turbine and a tower support of the support structure. Flanges of the tower and the tower support are either bolted to each other, sandwiching the transition piece in between, or bolted into the transition piece for fixation.

A transition body may be disposed between upper and lower tower sections of a tower for a wind power station. Some example transition bodies may include a substantially annular upper connection flange for connection to the upper tower section, and at least three substantially annular lower connection flanges, each of which may connect to a corner leg of the lower tower section. The transition body may have several segments disposed about a central tower axis, with the number of segments corresponding to the number of corner legs. Upper peripheral sections of the segments may form an annular circumferential connection envelope that supports the upper connection flange. Lower sections of the segments may form annular circumferential segment envelopes that support the lower connection flanges. The segments may be disposed at acute angles and converge into one another at or near the upper connection flange.

Example embodiments relate to apparatuses, systems, and methods for securing an offshore platform to a bottom of a body of water comprising a shear assembly and a sleeve assembly. The shear assembly is operable to secure to the offshore platform at a first end and having a first connector portion at a second end. The sleeve assembly comprises a sleeve body forming an interior opening, the interior opening operable to receive at least a pile. The sleeve assembly further comprises a second connector portion secured to the sleeve body, the second connector portion securable to and un-securable from the first connector portion of the shear assembly.

A method for constructing an offshore wind turbine includes: attaching all or a part of electrical products to a tower on land; stowing, on a work platform, the tower to which the electrical product is attached; and disposing, on a foundation, the tower, to which the electric product is attached, by using a crane of the work platform in the sea. In addition, the electrical products are classified into special high-voltage devices and the other electrical products, the special high-voltage devices are modularized on land, the other electrical products are attached to the tower on land, and the modularized special high-voltage devices and the tower, to which the other electrical products are attached, are disposed on the foundation by using the crane of the work platform in the sea.
