55000 t散货船在风浪联合作用下的系泊试验研究

Mooring test of 55000 t bulk carrier under combined action of wind and wave

通过几何比尺1∶50的物理模型试验,对55 000 DWT散货船在风、浪不同组合条件下船舶系泊的运动量、系缆力以及船舶靠泊产生的撞击力和撞击能量进行了研究。分析表明系缆方式二艉横缆的缆绳长度比系缆方式一增加2.0～3.8倍时,使得横缆受力有所减小,艏、艉缆和艏、艉横缆绳受力更为均匀;在推荐的系缆方式二中,港内波浪周期在12 s时,从受力角度来看,限制波浪工况为H4%≤0.5 m;从运动量角度来看,限制波浪工况为H4%≤0.6 m。文章在上述分析的基础上,推荐了合理的系缆方式,为工程设计提供了参考。

Through the physical model test of 1∶50, the amount of mooring, the mooring force and the impact force and impact energy of the 55 000 DWT bulk carrier under the different combinations of wind and wave conditions are studied. The analysis shows that when the length of the cable of the tethering method 2 is 2.0 to 3.8 times larger than that of the tethering method 1,the force of the transverse cable is reduced, and the cable of the cymbal, cable and cymbal is more uniform. In the recommended tethering method 2, when the wave period in the port is 12 s, the wave condition is limited to H4%≤ 0.5 m from the point of view of force;from the point of view of the movement, the wave condition is limited to H4%≤ 0.6 m. Based on the above analysis, the reasonable tethering method is recommended, which provides a reference for engineering design.
