A flange is provided for connection to a complementary flange, and wherein the flange includes an annular connection face to lie against a complementary annular connection face of the complementary flange; a first body section with a primary bolt circle including an annular arrangement of inclined openings to receive a set of fasteners for connecting the flange to the complementary flange and a second body section with a secondary bolt circle including an annular arrangement of openings to receive a set of fasteners for connecting the flange to an interim structure. Also provided is a method of handling a cylindrical tower section equipped with such a flange.

A windmill construction (10), comprising a rotor-nacelle assembly (12) with blades (14), a tower (16), a substructure (20) and a foundation (22). The substructure (20) comprises a first guide collar (24) and a second guide collar (26) for support of the tower (16), said first guide collar (24) being located in a lower part of the substructure (20) and said second guide collar (26) being located in an upper part of the substructure (20). The substructure (20) comprises a jack-up assembly (30) for receipt of modular tower segments (18), said tower segments (18) are arranged to be assembled in the substructure (20) and erectable by the jack-up assembly (30) to produce an assembled tower (16). The invention is also directed to a method for assembly of a windmill construction.

An electrical utility upgrade system and method for an existing transmission tower having a foundation, a tower structure and an electrical circuit. The upgrade system includes an exoskeleton structure coupled the existing tower structure and secured to the foundation. The system also includes a new tower top that is secure to the tower frame and includes a portion that extends above the existing tower cross arm. Forces acting on the new tower top are transmitted through the exoskeleton structure. The method includes adding the new tower top section and removing the existing tower cross arm and securing the existing or new conductors to the new tower top. The system is design to transfer forces exerted on the tower through the exoskeleton structure and to the foundation to reduce forces acting on the tower structure.

A modular post for use in a barrier system comprises a post component and a base. The post component is configured to be attached or attachable on, to or in the base in a deployed configuration. The post component is configured to be housed within the base when the modular post is in a stored configuration. A method of using a modular post suitable for use in a barrier system is also provided. The method comprises providing a post component and a base. The post component is configured to be attached or attachable on, to or in the base in a deployed configuration. The post component is receivable or configured to be housed within the base when the modular post is in a stored configuration.

A system for manufacturing a structure includes a supporting frame assembly moveable in a vertical direction of the structure. Further, the system includes an additive printing assembly secured to the supporting frame assembly. The additive printing assembly includes at least one printer head configured to dispense a first cementitious material. The system also includes a reinforcement dispensing assembly supported by the supporting frame assembly. Thus, the reinforcement dispensing assembly is configured to automatically and continuously dispense a plurality of reinforcing members as the structure is printed and built up via the at least one printer head and as the supporting frame assembly moves in the vertical direction.

A tower section for a wind turbine is provided. The tower section includes a tensioning arrangement having at least one tensioning device attached to three or more attachment points associated with the tower section. The attachment points are located proximate to an end of the tower section. The or each tensioning device is under tension and provides radial stiffness to the tower section. A method for assembling a tower for a wind turbine is also provided. The method includes providing a tower section, attaching a tensioning arrangement including at least one tensioning device between three or more attachment points associated with the tower section and located proximate to an end thereof, and applying tension to the at least one tensioning device so as to provide radial stiffness to the tower section.
