PROBLEM TO BE SOLVED: To provide a foundation of a type corresponding to uneven land for an offshore wind power generator or the like, for eliminating the necessity of preparations for the seabed surface prior to installation of the foundation, enabling the foundation to be accurately installed irrespective of the unevenness of the seabed surface, and allowing the verticality of an upper structure to be easily corrected even if the foundation is tilted because of aged deterioration, resulting reduced number of the days needed for marine operation, etc. SOLUTION: The foundation 11 to be provided below the offshore wind power generator 1 comprises a weight portion 12 consisting of three weights 21 installed on the seabed surface and a foundation beam 22; a universal coupling 13 for connecting the center of the weight portion 12 to the lower portion of a main column 2; and a connector 16 having a length adjustment device 15 for connecting the upper surface of each weight 21 to the base part of the main column 2 via the universal coupling 14. The foundation 11 assembled above the ground is hoisted using a crane ship, is transported over the sea, and sunk in a predetermined installation site. Then the length adjustment device 15 is operated to adjust the length of the connector 16 to make the main column 2 vertical. |
