In the recent decades, wind energy has emerged as an essential resource for the socio-economic development and economic growth in our life which helps in reducing the dependency on fossil fuels. It has been estimated that about 10 million MW of energy are continuously available in the earth’s wind and it provides security at a time when decreasing global reserves of fossil fuels threatens the long-term sustainability of global economy. Thus, wind energy emerged as a promising technology for the utilization of offshore wind resources for the large scale generation of electricity. It has been observed that relatively low surface roughness of the ocean results in higher wind speeds. So the offshore windmills are the best possible options for generating electricity.
Recently, most of the offshore wind power projects are proposed in deep water where the winds are of sufficient velocities. Thus the wind turbines on the floating support are the best solution to utilize the wind resources in areas with deep water depths. In order to generate more electricity, now a days various types of floating wind turbines are designed and are under study for deep water depths by various researchers and engineers.
In the present paper, a detailed literature survey of research and development on offshore floating wind turbines and its applications are presented. The performances of various floating wind turbine models in different water depths are outlined to understand the importance of the water depth for power generation. The working principle of various floater concepts and the conceptual designs for floating platforms used for floating wind turbines are also described. The detailed research work that has been undertaken in the study of floating wind turbine technology by various researchers and research institutes are discussed. A brief description on the various components of the wind turbine, the role of various techniques and loads for design, control systems and economics of wind energy conversion system are also presented in detail.
