A tower foundation assembly includes a foundation having a base section and a receptacle atop the base section. The receptacle of the foundation defines a bottom surface and an inner perimeter wall. The tower foundation assembly also includes a tower, such as a wind turbine tower, secured to the inner perimeter wall within the receptacle of the foundation. As such, the tower extends in a longitudinal direction from the foundation.

A system and method are used for transporting a plurality of tower sections of a wind turbine on beds of transport devices, such as flat railcars. Supports affix at support locations on beds to accommodate at least one of the tower sections on each of the transport devices. The supports can include bed supports, such as tabs, extending from the beds, and can include cradle supports with slots that engage on the tabs. A circumferential dimension of a cradle is adjusted on each of the supports against which the tower section rests. Each of the tower sections is then supported with at least two of the supports by loading the tower sections on the transport devices. An end of each of the tower sections is then affixed to a flange on at least one of the supports on each of the transport devices.

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.

A modular foundation includes a central portion and a plurality of legs non-rotatably secured to and extending from the central portion. The plurality of legs are substantially equally spaced apart from each other wherein each leg includes a proximal end and a distal end. A ballast support adapter is attached to the distal end of each leg wherein the adapter is configured to support one or more ballast plates such that each leg can be independently positioned for leveling the foundation and supporting the monopole in a vertical position. A platform supports the monopole and is pivotally attached to the central portion wherein the platform is configured to move from a vertical position to a horizontal position.

The present invention relates to a manufacturing process in situ of concrete towers for wind turbines which enables executing a design of concrete tower manufactured in situ by means of climbing formwork, which reduces the execution time of the concrete tower, where the invention also relates to the associated concrete tower for wind turbine.

A deployable mast structure (100) is disclosed, comprising a body configured to adopt a tubular shape when the mast structure is in a deployed configuration, and a plurality of openings (102) formed in a wall of the body so as to define a plurality of integral tape-spring hinges (103) in the wall of the body, the plurality of openings being configured so as to permit the body to collapse along its longitudinal axis into a stowed configuration when the tape-spring hinges are buckled. In the stowed configuration, the integral tape-spring hinges are configured to exert a force which urges the structure towards the deployed configuration. Since the mast structure collapses along its longitudinal axis, the structure only occupies a small volume in the stowed configuration. A method of fabricating the deployable mast structure from a layered composite material is also disclosed.

A method assembles a wind turbine in a non-vertical orientation. The turbine has a nested wind tower with a plurality of tower sections, including a first inner tower section radially inward of an outer tower section. Each of the tower sections has a wall with an inner surface and an outer surface. The first inner tower section has a connection interface at or near its bottom end, and the outer tower section has a counterpart connection interface at or near its top end. The tower has a friction reduction member configured to reduce friction between the first inner tower section and the outer tower section as the first inner tower section is extracted in a non-vertical orientation. The first inner tower section is extracted in a telescoping manner until the connection interface contacts the counterpart connection interface. The method also secures the connection interface and the counterpart connection interface together.

A side saddle slingshot drilling rig includes a left and right substructure including a left and right lower box. The side saddle slingshot drilling rig includes a drill rig floor mechanically and pivotably coupled to the left and right lower boxes such that it is pivotably movable from a lowered position to a raised position. The drill rig floor includes a V-door. The V-door is positioned on the V-door side of the drill rig floor. The V-door side of the drill rig floor is oriented to face the right substructure. A mast coupled to the drill rig floor may include an open side, defining a mast V-door side. The mast V-door side may be oriented to face the right substructure. The mast may pivot into its raised position or may be a bootstrap mast.
