PROBLEM TO BE SOLVED: To provide a tower type hydro-structure that can be easily installed on water by a simple configuration without using any large-scale facility such as a large-sized crane ship and provide an installation method therefor.SOLUTION: This invention relates to an ocean wind turbine 1A including a cylindrical tower structure 2 having a bottom part capable of generating buoyancy and installed on ocean, and each of a second ballast section 12 and a third ballast section 13 above the second ballast section 12 is installed in the tower structure 2. Flowability ballast 21 is filled in the third ballast section 13, the ocean wind turbine 1A is kept on the ocean while being layed flat, towed up to an installation ocean area while keeping this layed flat state. Upon reaching up to the installation ocean area, the flowability ballast 21 within the third ballast section 13 is moved into the second ballast section 12 to cause the ocean wind turbine 1A to move from the layed flat state to an upright state and the ocean wind turbine 1A is installed on the ocean.

    【課題】大型クレーン船等の大がかりな設備を用いることなく、簡易な構成で容易に水上設置することができるタワー型水上構造物およびその設置方法を提供する。【解決手段】浮力を発生可能な有底円筒状のタワー構造物2を備え、洋上に設置される洋上風車1Aであって、タワー構造物2の内部に、第2バラスト区画12とその第2バラスト区画12の上方に第3バラスト区画13をそれぞれ設けるものとする。そして、第3バラスト区画13内に流動性バラスト21を充填して洋上風車1Aを洋上で横転状態に保ち、この横転状態のままで設置海域まで曳航し、設置海域に到着したら、第3バラスト区画13内の流動性バラスト21を第2バラスト区画12内に移動させて洋上風車1Aを横転状態から直立状態に移行させることで、洋上に洋上風車1Aを設置するものとする。【選択図】図2
