To mount a windmill on a tower of an offshore wind power generation facility without using a large-sized floating crane.SOLUTION: A method includes: a first step of mounting a tower 6 on a floating body 4 same as a floating body 4 of an offshore wind power generation facility 1 and floating a crane mounted floating body 2 in which a crane facility 3 is provided on the top of the tower 6 on the sea; a second step of making a barge type platform 37 on which a windmill 7 is mounted proximate to the crane mounted floating body 2 and hitching the windmill 7 over a hook of the crane facility 3; a third step of dynamically lifting the windmill 7 by draining ballast water of the crane mounted floating body 2; a fourth step of causing the floating body 4 of the offshore wind power generation facility 1 which is installed on the sea, approach the crane mounted floating body 2 and connecting the suspended windmill 7 to the top of the tower 6 of the offshore wind power generation facility 1; and a fifth step of moving the ballast water corresponding to a windmill weight from the floating body 4 of the offshore wind power generation facility 1 to the crane mounted floating body 2, thereby replacing the weight of the windmill 7 to the side of the floating body 4 of the offshore wind power generation facility 1.SELECTED DRAWING: Figure 10
