中英规范中船舶系缆力计算比较

为研究中英两国规范中船舶系缆力计算的差异,对比JTS 144-1—2010 《港口工程荷载规范》和英标BS 6349-1:2000,针对不同船型及风(流)向角的船舶系缆力进行比较分析。结果表明,集装箱船国标的风压力计算值要小于英标,而油船则大于英标;集装箱船国标的水流力计算值要小于英标;油船仅在流向角为90°时国标计算值大于英标,其他流向角时则小于英标。可为海外工程设计提供参考。

Comparison of mooring force calculation in Chinese and British standard

To study the differences of mooring forces in Chinese and British standard,we analyze the mooring force in different ship types and wind(current)angles by comparing JTS 144-1-2010 Load Code for Harbor Engineering with British standard BS 6349-1:2000.The results show that the wind force of container ships calculated by Chinese standard is smaller than that by British standard,while the wind force of oil tanker is larger.The current force of container ship calculated by Chinese standard is smaller than British,and so is oil tanker except when the angle of the current is 90°.The conclusion can be used as a reference for design of overseas project.
