... situation, lock-in happens if VIM frequency is identical to sway frequency. In that case, lock-in of heave, pitch, yaw as well as sway, roll may occur due to coupled effect if the floating body is strongly connected with tendons. And, it may affect fatigue damage of tendons. The objective of this study...
