<P>PROBLEM TO BE SOLVED: To provide a structure of connection and a method for installation for offshore wind power generation by which, in connecting the superstructure to the foundation in severe oceanographic conditions, the superstructure of a wind turbine tower can be connected safely to the top of the foundation in a relatively short period of time, and accuracy, strength, or the like in the connection can be secured easily. <P>SOLUTION: On the top surface center of the seabed fixed foundation 2, a projection 10 for connection such as a pin pile and the like made of steel, and a connection hole 11 formed at the bottom of a wind turbine tower 3 are functioned as devices for insertion guide-positioning in the connection work. An insertion guide plate 20 is inserted between a pair of right and left guide plates 21, 21. In a state that fastening flanges 13, 12 are separated, the side of the insertion guide plate 20 is pushed by a pushing device 22 to slightly rotate the wind turbine tower 3 in the circumferential direction so that bolt holes for the connection flanges 13, 12 are aligned with each other to screw the superimposed fastening flanges 13, 12. <P>COPYRIGHT: (C)2010,JPO&INPIT |
