The present paper is concerned with the prediction method for the motions and tensions of mooring lines on relaxation moored floating type oceanic architectual building in coastal zone. The motions and the tensions of mooring lines were estimated by the time domain numerical simulation in the present method. The present method includes the nonlinearty of mooring system, slow varying wave drift force and wind and current loads. We performed a time domain numerical simulation for motions and tensions of mooring lines on floating barge in two component waves. Also, the results obtained by numerical simulation were compared with the experimental results. The validity of present method was confirmed. Further, we performed the numerical simulation for motion and tensions of mooring lines on floating type oceanic architectual building by using the present method and practical method. Both results were compared and the applicability of the present method for the design of mooring line system was made clear.
