Due to the crisis faced to the extraction of energy as well as environmental pollution Floating offshore wind turbine (FOWT) can be the most practical and economic way to extract offshore wind energy resources in the deep waters of intermediate depth. Floating offshore wind turbine (FOWT) is a complex system that for these structures must be solved, coupled Non-linear motion equations with considering Excitation forces and nonlinear damping include to all of wind and wave effects at time domain. In percent study the analysis of motion response for operation condition in translational and rotational motion for investigation of functionality and structural stability of floating offshore wind turbine under buoyancy and Hydrodynamics forces. In this way, the numerical model has been developed in MATLAB software. Before the dynamic simulation of FOWT has been verified by modules. Finally the obtained results in time domain is represented, the extracted result show that in translational motions, the maximum and minimum of buoyancy forces are in Heave and sway direction respectively and maximum and minimum of Hydrodynamic forces values are in surge and sway direction respectively.
Also, in rotational maximum and minimum of Buoyancy forces are in roll and yaw direction respectively and maximum and minimum of the Hydrodynamic forces are in yaw and pitch direction respectively.
