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.
