PROBLEM TO BE SOLVED: To provide a floating body for wind power generation, which for reducing rolling/pitching of the floating body, moves weights to move the center of gravity according to movement of the center of buoyancy of the floating body and actively produces a rolling/pitching reducing moment.SOLUTION: A straight line connecting the center of buoyancy, which is the center of buoyant force acting on a floating body 1 for wind power generation, and the center of gravity of all total weight of the weight of a wind power generation facility mounted to the floating body and the weight of the floating body is set as a central axis. Plural weights 27, 47, 67 are provided to rotate around the central axis. The weights are divided into two groups. The first group of weights 27, 47 are rotated in the same direction at the same rotation speed, and the next group of weight 67 is rotated in the opposite direction to the former direction at the same rotation number with the former rotation number. The radius of rotation 81, 82 and the rotation speed of each weight are adjustable.SELECTED DRAWING: Figure 5
【課題】浮体動揺を少なくするため、浮体の浮心が移動するのにあわせて、重りを移動させて重心の移動を図り、減揺モーメントを能動的に作り出す風力発電用浮体を提供する。【解決手段】風力発電用浮体1にかかる浮力の中心である浮心と、浮体へ搭載される風力発電設備の重量および浮体の重量の全合計重量の重心とを結ぶ直線を中心軸とし、その中心軸の廻りを回転する複数個の重り27,47,67を設け、その重りを二群に分け、最初の一群の重り27,47を同じ方向に同じ回転速度で回転させ、次の重りの一群67を前記方向と反対方向で前期回転数と同じ回転数で回転させ、各重りの回転半径81,82、回転速度を調節可能とする。【選択図】図5
