在强风大浪等恶劣海况下，双船码头的系泊安全性至关重要。为确保其稳定与安全，有必要对双船码头的系泊响应特性进行深入研究。本文采用水动力软件AQWA，基于三势流理论对2艘10.5×104 t散货船并排码头系泊进行数值仿真研究，得到在风流浪联合作用下不同浪向角下系泊系统动力响应特性。研究结果表明，双船并排码头系泊时，外船的运动响应大于内船；在离岸风下，系泊系统的缆绳张力较大；在向岸风下，系泊系统的护舷力较大；环境载荷同向时，缆绳张力及护舷力较大。为双船码头系泊的安全性提供了参考。
In order to ensure the safety of mooring in the severe sea conditions such as strong wind and big waves, it is necessary to study the mooring response characteristics of the two-ship quay. Based on the three-dimensional potential flow theory, this paper uses the hydrodynamic software AQWA to conduct numerical simulation research on two 105,000 ton bulk carriers mooring side by side under the action of wind vagrancy, and obtains the dynamic response characteristics of the mooring system under different wave direction angles. The results show that the motion response of the outer ship is greater than that of the inner ship when the two ships are mooring side by side. Under the offshore wind, the mooring system cable tension is larger. Under shore wind, the fender force of mooring system is larger. When the environmental load is in the same direction, the cable tension and fender force are larger. This paper provides a reference for the safety of mooring in two-ship quay.
