Wind turbines are one of the best solutions for renewable energy, although wind turbines do not produce air pollution, but wind turbines with greater power, for example above 5 MW, wind turbines produce loud noises, are an eyesore and require a large area. soil. One solution to overcome this is to create an offshore floating structure on the high seas. The floating structure is used as a foundation to support the wind turbine. So far, the wind turbines have been built offshore and are located in shallow waters with a depth of no more than 50 meters with the foundation construction planted on the seabed. Accurate modeling of the wind turbine column structure system is important to determine the characteristics of the structure against the load it receives in unexpected sea conditions. These loads must be controlled so as not to damage the turbine and besides being able to optimize the turbine rotor to capture wind energy optimally. The stress calculation is carried out by simulation and a real model is made to be tested on the Kenjeran beach, Surabaya. Waves and wind speeds that vary cause surge, heavy and pitch motions in the floating structure are quite stable and have no significant effect on the rotation of the rotor. For a wind speed of 2.1 m/s the electrical voltage is generated and at a wind speed of 18.2 m/s an electric voltage is generated.
