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 WebThe shape of a mooring line is determined by the spatial distribution of the mass centers of all its segments. Dynamic coupling of the mooring lines with the moving objects is implemented in the way that the line dynamics provides tension force for the objects while the objects supply the tether end locations for the lines.
