Abstract

The invention relates to a method for assembling an offshore wind turbine that is separated into two parts that are pre-assembled in a port: a jacket-type lattice substructure (15) anchored to the seabed with a foundation and a superstructure that includes a transition piece (4), a tower (1), a nacelle (2) and blades (3) transported floating in a vertical position. Tripod supports (5) are anchored on board the double-pontoon vessel (8) that is braced (9) at the bow and stern, and a triangle (7) supporting the superstructure is disposed on the tripod supports. During the transport phase, the hydraulics (14) included inside the tripod supports (5) are retracted, the movable parts are connected by a bolted joint, and the vessel (8) is ballasted. Once the positioning on the jacket (15) has been carried out, both parts are fastened by moorings (16), movement limiters (18) and impact limiters (18'), the load is transferred with the lowering of the hydraulic cylinders (14), and contact occurs between the upper portion of the jacket (15) and the receiver of the passive coupling system (23). Once the assembly is complete, the passive coupling system (23) arranged on the transition piece is recovered, the triangle (7) is dismantled, and the bracing (9) of the stern is folded down or removed to release the vessel (8).

Abstract

Disclosed is a method for assembling an offshore tower formed by a trellis part comprising different sections (4) connected together, a transition piece (5) and a tubular tower section (11). The entire assembly is modular and is connected using maintenance-free screws, with an anti-saline treatment. Assembly is carried out horizontally on a dock of a port, without need for large spaces. Once completely assembled and closed at the top end (18), the tower is transported, using floats (14), to a foundation (19) where it is then pinned. The assembly of a gondola (25) and blades is completed using an external crane (24) assembled using an internal hoist (21). The external crane (24)is removed once the process is complete, and the operation is finished with internal wiring.

Abstract

The invention relates to a method for building concrete foundations for lattice-type offshore structures and to foundations built using this method, which has the main aim of replacing the piles used to anchor lattice structures to the seabed (7) with blocks of on-site reinforced concrete (1) which grant the necessary stability to the lattice structure (2), doing away with all pile-driving works but without performing any structural modification of said structure. Said elements (1) are positioned using templates (12). The advantages of this novel invention lie in the possibility of installation on any type of terrain, providing a perfect connection between the seabed and the foundations thanks to on-site concreting, as well as its ease of construction, reduction of noise emissions and of auxiliary means.
