PROBLEM TO BE SOLVED: To provide an offshore wind turbine installation method capable of reducing work expenditures not using SEP but using a fixed type lift work table.SOLUTION: On a work table 5 are installed separated towers 14, a nacelle 15 and blades 17. A lift work table 1 is placed on floaters 9 under a state in which lift legs 3 are not reached to a water bottom 19, towed while being floated on the water surface 21 and transported to a prescribed water area. Then, the lift legs 3 are lowered down to the water bottom 19 with lifting devices 7 and supported at the water bottom 19, the work table 5 is lifted up to a prescribed level on the water surface 21. Additionally, the floaters 9 are removed from the lift legs 3 and moved out of the prescribed water area. Then, a pile 25 is driven into the water bottom 19 under application of a jib crane 11 installed on the work table 5 while a recess part 23 at the work table 5 is applied as a work space, the divided towers 14 are connected in sequence on the piles, the nacelle 15 and the blades 17 are connected on the towers 14 to complete an offshore wind turbine.SELECTED DRAWING: Figure 1 |
