摘　　要：码头结构设计和系船柱选型以船舶系缆力为重要条件,而各国规范中的船舶系缆力计算方法不尽相同。针对船舶所受水流力的计算方法差异,选取中国JTS、西班牙ROM、OCIMF指南、英国BS 6349共4种常用码头结构设计规范进行对比,并以30万t油船为例进行水流力的计算和分析。结果表明:1)各国规范对于船舶所受水流力的计算公式、相对水深比、设计流速、适应范围等均存在一定差异;2)对于30万t油船,ROM计算所得的船舶所受水流力最大,BS 6349最小。结论可供类似工程设计参考。Mooring force is an important factor in wharf structure design and mooring bollards selection. The calculation methods of ship mooring force are different between different codes. Regarding the differences in current force calculation, this paper selects four wharf structural design specifications for comparison, namely JTS of China, ROM of Spain, OCIMF Guide and BS 6349 of Britain, and takes a 300,000-ton tanker as an example. The results show that: 1)there are some differences in the calculation formula, relative water depth ratio, design current velocity and adaptive range of the current force on ships;2)The current force of the 300,000-ton tanker calculated by ROM is the largest, while the BS 6349 result is the smallest. The conclusion can be used as references for similar engineering design.
