EXPERIMENTAL FORMULA FOR THE WAVE-INDUCED SHIP MOORING FORCE

Xiangwei Meng, Xue-ping Gao, Wen-zhong Zhang, Yun-peng Jiang

Abstract


The wave force dose not considered at the formula of mooring ship cable force in the Load Code for Harbor Engineering[JTJ215-98]. This brought the inconvenience to the calculation of designed cable force for mooring ship. By means of analysis for the laboratory model test result of mooring ship cable force under wave effect, Wave force formula of mooring ship under wave effect was gained. This formula well reflected the influence of ship size, ship load , ship rolling period, ship pitch period, wave period and wave height. The formula can be used in the calculation of standard value of mooring ship cable force under the wave effection, also it can be used to instruct the wave model test for mooring ship.
