Following the statistical analysis on the condition related to typhoon？HH？HHs paths and scales in the first year project of a four-year sequential project an ANN alert model of ship escape from Hua-Lien harbor during typhoon period will be developed in this project. The conditions of official annual ship escape reports from 1996 to 2003 are collected and classified into four grades and related to the corresponding typhoon position and scale. Typhoon？HH？HHs path, scale, maximum wind speed and position are the dominant affecting factors to be the input parameters in the proposed ANN model. Another aim of this project is to remedy the possibly missing tide and wave data during the period of an approaching typhoon due to instrument loss or damage. The missing data often happens at the time of the strongest typhoon that can cause the maximum wave heights. Thus, it is very important to evaluate the possible maximum wave height during the period of each typhoon, even when the instrument for waves is beyond work. The integrated ANN model has some functions that are to calculate typhoon？HH？HHs wave, storm surge; to remedy the missing wave or tidal data. The completely developed model in the future can provide the ships in the Hua-Lien harbor with duly alarms for escaping from severe wave impacts. The proposed integrated ANN alarm model can provide a good reference for harbor managements on ship mooring safety and is available for reducing harbor damages due to the typhoons.
