Wind turbines on floating support platforms are designed to be installed in a deep offshore environment several miles off the coast and in water depths greater than 60m. Effects from sea ice, varying mean sea level, and marine growth constitute additional loads that must be considered in a real design process. Design Modeler is the ANSYS tool used to create geometry for hydrodynamic systems. Surface bodies are only supported by ANSYS AQWA thus entire solid body which is created using the design modeler is transformed in to surface body. Four different mini Tension leg platforms were prepared all the dimensions and standards are followed from the guidelines of national renewable energy laboratory United States. This paper focused on the motion performance of tension leg platform supported wind turbine prototypes in Nicobar coast of India. The wind, wave and ocean current data were obtained and inputted in to the AQWA modules and the result is validated with respect to time domain.
