DYNAMIC ANALYSIS OF MOORED TANKERS

A loaded 200 kDWT tanker moored in shallow water by means of a single bow anchor chain is subjected to wind and waves. Wind loads on the tanker were measured in a stiff mooring arrangement. The measured wind loads together with the calibrated wave train were used as input to a numerical model to predict the dynamic behaviour of the anchored tanker. A good correlation with the measured tanker motions and mooring loads was found. The model can be used in the design of mooring systems and anchoring equipment for arbitrary water depths. Important features which are accounted for include bottom friction, low and high frequency tanker motions and chain dynamics.
