【 摘 要 】

In the past, only the ship motion due to wave is studied. This study is focused on the ship motion induced by a steady oscillating wind. The oscillating wind is assumed to be sinusoidal of a constant frequency. The wind direction 9, number of mooring lines and the wind frequency are the parameters in simulating an Evergreen's Ever Garden class container ship. The results show that the worst angle between the quay and the prevailing wind direction is 45°. Surge and roll are the most significant motions induced by the oscillating wind. By changing the number of mooring lines, the natural frequency can be kept away from the dominant wind frequency, except roll.
