WebThe surge motion of the moored vessel is estimated by analyzing the vessel motion as a harmonically forced linear single degree of freedom spring mass system. Methods out-lined in a paper by F.A. Kilner [5.8] can be used to calculate the vessel motion. WebFor surge motion, the total motion mainly comes from the nonlinear low frequency component. For pitch motion, the linear response is dominant in small k p A l i n e a r. When the steepness k p A l i n e a r increases gradually, the second-order low-frequency response of pitch motion will increase rapidly and dominate the total response. Keywords
