The mooring force of a ship is not only influenced by natural conditions such as wind,waves and current,but also by the ship's own factors such as ship type,tonnage and deadweight,as well as a series of factors such as cable materials,mooring methods and dock facilities.This paper takes the model ship as an example,simplifies the establishment of one ship model through the study of various input elements of the mooring line and uses MOSES software for numerical calculation.According to the calculation results,the mooring force of a ship's wharf typhoon defence is analyzed and predicted,and the improvement measures and precautions are put forward to improve the safety of mooring cables for wharf typhoon defence,which would provide reference and inspiration for other ships'corresponding dock anti typhoon mooring cables.
