Offshore wind energy is widely recognized as a renewable energy source that has the potential as a global energy source. Although the use of coastal wind turbines has been successful, it has been challenged in terms of visual, acoustic and environmental impacts. In addition, in terms of technology, it is difficult to achieve high levels of energy from coastal wind resources due to low annual average speed; Therefore, the wind energy industry is trying to make more use of the deep-water wind resources. However, before developing these types of deep-water turbines, economic challenges and technical problems must be resolved. Mooring failure is one of the major issues in the design of offshore... 

For many years, humans have been able to use wind energy to meet some of their needs. By improving science and the discovery of electricity as the mother of energy that is very easy to use, mankind thought of converting wind energy into electricity, so wind turbines were invented. Despite the wide spread of onshore wind turbines, their visual, acoustic and environmental negative effects still cause dissatisfaction among the residents of the areas where these turbines are installed. Also, the high wind speed in the seas compared to the land ares has caused the interest to use offshore wind turbines to increase in the past years. For this reason, an attempt has been made in this thesis to...
