Mooring problems are still serious issues in port construction and operation. Although there are many studies are carried out about moored ship motions or long period waves, effective countermeasures are not accomplished in most harbours facing to open seas. On the other hand, it is known that operators require the offer of wave information near harbours in detail when sea conditions become serious. In this study, the new numerical model is constructed for the prediction of the mooring criteria. It is based on the theory of Kalman Filter, wave estimation inside typhoons and wave decay as swells. It is characteristic that the prediction model do not need huge amount of input data such as meteorological models. The accuracy is verified for "A Port" facing to the Pacific Ocean when swells or wind waves propagate from typhoons. Moreover, the prediction model applies for other points facing to the Pacific Ocean. This new model makes possible to predict the mooring criteria at 0.5-2 days before under the influence of typhoons. Finally, we propose the berth operation system to monitor the mooring criteria using this prediction model in harbours facing to open seas.
