With the development of large-scale ships, the combined action load of wind, wave and current in the harbour is getting larger and larger. Accurately predicting the Mooring Load of mooring vessels in the harbour can help designers to select appropriate mooring equipment, get a reasonable layout of mooring equipment, and effectively improve the mooring efficiency.

In this paper, a 16000 TEU container ship is taken as the research object, and its mooring conditions under typical wharf conditions and specific loads are calculated and analyzed by using BV Classification Society's Ariane mooring software. The motion state and cable force of the ship are calculated by three-dimensional time-domain method. The influences of the cable material, loading condition, cable arrangement position and cable angle on the calculation results are compared and analyzed. The design suggestions for the mooring arrangement of the ship wharf are put forward.


Ships in the harbour will be affected by the combination load of wind, wave and current, and it will be affected the nonlinear constraint of the cable.At this time ,the ship will have six degrees of freedom of nonlinear motion(Hu Y, 2012; Cumins WE, 1962).With the development of large-scale ships, the wind area, wet surface area will increase, and various loads will increase accordingly(WANG HR 2015). Therefore, it is significance to select economical and safe mooring devices and design suitable mooring arrangement.

While, the large container has high freeboard and large wind area, cable will suffer large mooring load under severe sea conditions(Li Z, 2003). Once the mooring cable is broken, the ship will crash the wharf and cause a self-damaging accident. The consequences will be very serious. Therefore, it is necessary to calculate the motion response and cable force of large container ships to ensure the safety of ship mooring.


The hydrostar software is used in this paper, it can be used to calculate the wave-structure interaction. The wind load, current load, multi-body structure coupling, forward velocity and internal fluid motion can be considered in the calculation. The calculation principles are as follows:
