N2 - In this paper, two multi point mooring systems which are under the action of periodic wave excitation are considered in order to find ou the approximate responses by using Runge Kutta Method. One of the mooring systems is anchored to the seabed with four mooring lines while the other is anchored with six mooring lines. On both systems, a strong nonlinearity is described by increasing restoring force. For possible mooring line densities, change in excursion downstream anc tension at the buoys are taken into account respectively. By introducing different sea conditions into these multi point mooring systems, wave force acting on each system is observed. For certain excitatior frequencies a number of chaotic phase diagrams are obtained whicl yields into instability of these systems. At the end, comparison of the two systems is figured out to understand the effect of number of mooring lines on the responses of each system. Copyright
