Abstract

A wind turbine installation is provided. The installation includes a wind turbine tower or tower section, a receiving part of a wind turbine foundation installation, connection means suitable for connecting the wind turbine tower or tower section to the receiving part, whereby a lower end of the wind turbine tower or the tower section is flange-less.

Claims

1-13. -13. (canceled)

14. A wind turbine installation, comprising:

a wind turbine tower or tower section;

a receiving part of a wind turbine foundation installation,

a connection device suitable for connecting the wind turbine tower or tower section to the receiving part,

wherein a lower end of the wind turbine tower or the tower section is flange-less.

15. The wind turbine installation according to claim 14, wherein the connection device is bolted or welded to the flange-less lower end.

16. The wind turbine installation according to claim 14, wherein the connection device is bolted or welded to the receiving part.

17. The wind turbine installation according to claim 14, wherein the receiving part is segmented.

18. The wind turbine installation according to claim 14, wherein the receiving part is a foundation flange.

19. The wind turbine installation according to claim 14, wherein the receiving part is a transition piece of the foundation installation.

20. The wind turbine installation according to claim 18, wherein the foundation flange comprises at least one vertical section for connecting to the flange-less lower end.

21. The wind turbine installation according to claim 19, wherein the transition piece comprises at least one vertical section for connection to the flange-less lower end.

22. The wind turbine installation according to claim 20, wherein the at least one vertical section of the foundation flange or the transition piece is connected to the flange-less lower end by one or two splice plates as connecting device.

23. The wind turbine installation according to claim 21, wherein the at least one vertical section of the transition piece is connected to the flange-less lower end by one or two splice plates as connecting device.

24. The wind turbine installation according to claim 20, wherein the at least one vertical section is connected by an H-profile as connecting device.

25. The wind turbine installation according to claim 21, wherein the at least one vertical section is connected by an H-profile as connecting device.

26. The wind turbine installation according to claim 20, wherein the foundation flange is formed as a C-profile with two vertical sections, the flange-less lower end being inserted between the two vertical sections.

27. The wind turbine installation according to claim 21, wherein an end section of the transition piece is formed as a C-profile with two vertical sections, the flange-less lower end being inserted between the two vertical sections.

28. The wind turbine installation according to claim 20, wherein the connection device is a bent portion of the foundation flange to which the flange-less lower end is attached.

29. The wind turbine installation according to claim 21, wherein the connection device is a bent portion of the transition piece to which the flange-less lower end is attached.

30. The wind turbine installation according to claim 20, wherein the connection device is formed as an L-profile with a horizontal and a vertical section to which the flange-less lower end is attached.
