However, since the land on the land is difficult to obtain, the installation location of the wind power generator is moved to In the ocean.

Today's offshore wind turbines are installed in a suitable position in the ocean. The floating platform is connected with an anchor chain. One end of the chain is fixed at the seabed, and the wind turbine is a floating platform. At the top, the wind turbine is connected to the cable, and the other end of the cable extends from the pontoon towards the seabed and is connected to a suitable device.

Although the above-mentioned setting method has overcome the dilemma that the wind power generator cannot be set on the land, the floating platform will rotate in the floating platform due to the external force such as wind force, irresistible external force or tide. At this time, the anchor chain and the cable are entangled with each other, and in this state, the cable is easily damaged, so it takes a lot of money and manpower to trim.

In addition, since the floating platform floats on the sea surface, the portion of the floating platform that sinks under the sea surface may be in an indeterminate state, causing the wave to impact the entire floating platform, and it is easy for the floating platform to move up and down due to the action of the waves.
