In the 4th paper, the sway inotions of a two-dimensional body with a fender type nonlinear mooring system in waves was discussed and a difference between two calculation methods of C.C. and C.I. was found when the sway motions close to the natural frequency of a moored body occur. The numerical results were compared with experimental values and the validity of C.I. method was revealed. In this paper, the same comparisons are made for a rope and/or chain type nonlinear mooring system and the following differences betw the results of C.I. and C.C. methods are found in the following cases. ・When the floating body which is initially at rest with a loosen rope and/or chain starts its motion (i.e. in a transient stage under the action of wave forces). ・When the subharmonic sway motions appear. By comparing the numerical results with experimental values, the validity of C.I. method is discussed.
