国内外系缆力计算方法的对比研究

Comparative Study on Chinese and foreign Calculation Methods of Mooring Forces

为了了解国内外系缆力计算方法的不同,结合某工程实例,对比了国标和英标中风荷载、水流力和系缆力的不同。又用OPTIMOOR系泊分析软件进行数值模拟,通过与两种标准计算得到的系缆力进行对比,得出国标的系缆力计算结果更接近实际值,英标偏保守。也证明了OPTIMOOR数值分析是计算船舶荷载的一种有效的手段。

In order to know the difference of mooring force calculation between Chinese standards and foreign standards, the differences of wind force, flow force and mooring force have been compared between the two standards based on a project. Then mooring force is simulated with OPTIMOOR. The comparison of simulation results with those calculated by Chinese standards and British standards shows that the results calculated with Chinese standards are closer to actual force, and British standards are conservative. It also verifies OPTIMOOR is an effective method to calculate ship loads.
