Abstract
The invention relates to a method of mounting a wind turbine at a mounting location, said method comprising the steps of providing a foundation (33A, 33B), said foundation comprising a foundation body and pre-fitted upper attachment means vibrating at least a part of the foundation into the earth by transferring of vibrations into the structure of the foundation, mounting at least a part of said wind turbine to said upper attachment means (12) of said foundation. According to the invention, large scale wind turbines, especially offshore wind turbines, may be transported and mounted at the site in a cost-effective and expedient way.
Claims32
Method of mounting a wind turbine at a mounting location, said method comprising:
- providing a foundation;
- said foundation comprising a foundation body and pre-fitted upper attachment means;
- vibrating said foundation at least partly into the earth by transferring of vibrations into the foundation by means of a vibration arrangement attached to said pre-fitted upper attachment means;
- and
- mounting at least a part of said wind turbine to said pre-fitted upper attachment means of said foundation.
Wind turbine foundation comprising:
- at least one upper attachment arrangement adapted for mounting at least a part of a wind turbine;
- said upper attachment arrangement comprising at least one interface portion to which a vibration arrangement may be attached;
- said interface portion comprising at least a part of the foundation adapted for receipt of structural vibration from the vibration arrangement when said vibration arrangement is attached to the interface portion.
Wind turbine assembly comprising:
- at least one wind turbine foundation;
- said wind turbine foundation comprising an upper attachment arrangement adapted for mounting of at least a part of a wind turbine and said upper attachment arrangement comprising an interface portion to which at least one vibration arrangement may be attached;
- at least one wind turbine tower;
- at least one maritime vessel adapted for transportation of said at least one wind turbine foundation;
- and
- at least one lift arrangement comprising means for positioning said at least one wind turbine foundation and said vibration arrangement at a mounting location.
