| Outline of Final Research Achievements |
The first of the research results is development of the time domain dynamic analysis method of the structural response of a floating support structure based on the potential theory in addition to the analysis function of rigid body motion. This is a sophistication of the "Rotor-Floater-Mooring-Control Coupled Response Analysis Method" of the floating offshore wind turbine, and the development was completed.
The second result is the development of a simulator that can follow the process in which the mooring system breaks due to the collision between the floating offshore wind turbine and the drifting vessel which has entered the wind farm, and the floating offshore wind turbines drift in a chain reaction. The numerical model that describes the drifting behavior of a ship was improved and incorporated into the simulator. The trial simulation of the behavior and risk when the drifting ship entered a wind farm composed of floating offshore wind turbines was performed.
