日本海に面した港湾での高波高の発生予測に関する基礎的研究

抄録

In ports and harbors facing to the open sea, mooring ships have sometimes encountered severe wave condition in the winter, then the mooring ropes and fenders are broken. As the results, the accident of ship body damage has happened. In order to avoid such accidents, we should set the mooring criteria for the ship shifting to outside of the harbor. For the target N-port facing to the Sea of Japan, the critical offshore wave hight is known to be 5m by our previous research, so we try to forecast the wave height before 2 or 4 hours earlier. We propose several high wave forecasting methods using waves, winds and both data. If we use the 5 parameters method of wind and wave, we can forecast the critical conditions with 77% accuracy and 12 parameters method of wind, then 91% accuracy.
