中文摘要:

为评估V形浮体在风、浪、流等环境因素影响下的安全性，实现V形浮体的安全系泊，参照OCIMF常规船型码头系泊基本原则设计了两种不同的系泊方案，分别是利用码头的两垂直边进行系泊和V形浮体一侧片体与码头平直边进行系泊．基于三维势流理论，应用AQWA软件对该V形浮体进行频域水动力性能分析，通过时域耦合仿真计算得到其六自由度运动响应、系泊缆绳张力和护舷压力，并对不同角度环境荷载下的系泊系统进行安全校核．通过对比发现，利用V形浮体一侧片体与码头平直边进行系泊优于利用码头两垂直边进行系泊．分析了排水量、缆绳规格对系泊系统的影响，为提升系泊系统的安全性，可采取适当减小排水量、将尼龙缆绳改为迪尼玛缆绳等措施．

英文摘要:

In order to evaluate the safety of the V-shaped floating body under the influence of wind, waves, currents and other environmental factors, and achieve the safe mooring of the V-shaped floating body, two different mooring plans are designed with reference to the basic principles of the OCIMF conventional ship dock mooring, which are the use of the two vertical edges of the dock for the mooring and the one sheet of the V-shaped floating body with the straight edge of the dock for the mooring, respectively. Based on the three-dimensional potential flow theory, AQWA software is applied to analyze the frequency-domain hydrodynamic performance of the V-shaped floating body, and its six-degree-of-freedom kinematic response, mooring cable tension and fender pressure are obtained through time-domain coupled simulation, and the mooring system is safety-checked for different angles of environmental loads. By comparison, it is concluded that the mooring using the one sheet of the V-shaped floating body with the straight edge of the dock is superior to the mooring using the two vertical edges of the dock. The influence of water displacement and cable specification on the mooring system is analyzed, and in order to improve the safety of the mooring system, measures such as reducing the water displacement and changing the nylon cable to Dyneema cable can be taken.
