... is that the transverse line motion n (Fig. 1) can be much larger than the surge motion s. The energy dissipation due to drag forces on the lines, and thus the surge damping, can be considerably larger than that of the vessel itself. Ref. 1 analyzed the mooring line damping corresponding to the low frequency surge...
