(EN) FLOATING PLATFORM FOR HIGH-POWER WIND TURBINES
(ES) PLATAFORMA FLOTANTE PARA AEROGENERADORES DE GRAN POTENCIA
(FR) PLATE-FORME FLOTTANTE POUR AÉROGÉNÉRATEURS DE GRANDE PUISSANCE
Abstract
(EN)
A floating platform for high-power wind turbines, comprising a concrete substructure (1), said concrete substructure forming the base of the platform, which remains semi-submerged in the operating position, and consisting of a square lower slab (11) on which a series of beams (3, 31) and five hollow reinforced concrete cylinders (2, 21) are constructed, distributed at the corners and the centre of said lower slab (1); a metal superstructure (4) supported on the concrete substructure and forming the base for connection with the wind turbine tower, said tower being coupled at the centre thereof; and metal covers (5, 51) covering each of the cylinders (2, 21), on which the metal superstructure is supported and to which vertical pillars (6, 61) are secured, linked together by means of beams (7, 71) which join at the central pillar (61) by means of an element (8) whereon the base (9) of the wind turbine tower is secured.
(ES)
Plataforma flotante para aerogeneradores de gran potencia, que comprende una subestructura de hormigón (1), que constituye la base de la plataforma, que en posición operativa queda semisumergida, y está formada por una losa inferior cuadrada (11) sobre la que se construyen una serie de vigas (3, 31) y cinco cilindros huecos (2, 21) de hormigón armado, distribuidos en los vértices y en el centro de dicha losa inferior (1); sobre la que apoya una superestructura metálica (4) que constituye la base de conexión con la torre del aerogenerador, que acopla en el centro de la misma; la cual apoya en unas tapas metálicas (5, 51) que cubren cada uno de los cilindros (2, 21), sobre las que se fijan unos pilares verticales (6, 61), que quedan relacionados entre sí mediante vigas (7, 71), que se unen en el pilar central (61) con una pieza (8), en la que se fija la base (9) de la torre del aerogenerador.
