To ensure safe port operations around the world, it is important to solve mooring problems. In particular, the many ports that face open seas have difficulties with long-period waves. As a countermeasure, the installation of a breakwater is proposed for mooring safety. However, this often cannot be put into practice because of financial issues. Instead, port terminals control berthing schedules with weather forecasting. However, mooring problems remain unsolved, because of inaccurate wave forecasting. To quantify the current situation, numerical simulations are presented with ship motions, fender deflections, and rope tensions. In addition, novel simulations for mooring ropes are proposed considering tension, friction, bending fatigue, and temperature. With this novel simulation, the optimal mooring method in terms of safety and economic efficiency was confirmed. In terms of safety, the optimal mooring method is verified to minimize dangerous mooring situations. Moreover, the optimal mooring method shows economic benefits and efficiency. It can help to reinforce the safety of port terminals and improve the efficiency of port operations.

为了确保世界各地港口的安全运行，解决系泊问题非常重要。尤其是，许多面对公海的港口在长期波浪中都遇到困难。作为对策，建议安装防波堤以系泊安全。但是，由于财务问题，通常无法将其付诸实践。相反，港口码头通过天气预报控制停泊时间表。但是，由于海浪预报不准确，系泊问题仍未解决。为了量化当前状况，对船舶运动，挡泥板挠度和绳索张力进行了数值模拟。另外，考虑到张力，摩擦，弯曲疲劳和温度，提出了新颖的系泊缆绳模拟。通过这种新颖的模拟，确定了在安全性和经济效益方面的最佳系泊方法。在安全性方面，验证了最佳的系泊方法，以最大程度地减少危险的系泊情况。而且，最佳的系泊方法具有经济效益和效率。它可以帮助增强端口终端的安全性并提高端口操作效率。
