  • Publication number: 20100314884
    Abstract: The invention relates to a wind turbine (1) comprising a wind turbine tower (2) having a tower wall (22), a wind turbine nacelle (3) positioned on top of the tower (2) and noise reducing means (8) for reducing noise emission from the tower (2). The noise reducing means (8) comprises a beam (9) formed as an elongated strengthening member and one or more damping means (20), where the damping means (20) are arranged between the tower wall (22) and the beam (9), the damping means (20) being arranged so that relative movement between the tower wall (22) and the beam (9) result in dissipation of energy via the damping means (20) in order to reduce noise emission. The invention further relates to a method for reducing noise emission from a wind turbine tower (2) and use of a wind turbine (1).

  • Patent number: 7841143
    Abstract: The invention provides a tower construction e.g. for a wind mill and a method of laying a foundation of a tower construction. The tower construction (1) comprises a concrete element (2), and a base flange (3) from which a tower wall (4) extends upwardly. The base flange is supported by an intermediate support structure (5) positioned on the concrete element (2). The support structure (5) is more rigid than the concrete element (2) and comprises a resilient pressure distributing element (6) which is soft relative to the concrete element (2). Furthermore, the invention provides a support structure for a tower construction.

  • Publication number: 20030147753
    Abstract: The invention relates to a method of mounting elements in a wind turbine tower (10, 11, 12, 13, 14), whereby said elements are partly or completely attached to the wind turbine tower (10, 11, 12, 13, 14) by means of magnetic attraction forces.
