单点浮筒静密封失效及改进

摘要

针对单点浮筒形式的内转塔式单点系泊系统，利用200年一遇的环境条件，分析浮筒和船体之间的相对运动和接触力问题，找到一种可行的数值模拟方法以判定单点工作时静密封的有效性，并在发现有失效危险后给出可行性的改造方案。%Taking the single point mooring ( SPM) system of internal turret type as research object , the relative motion and the contact force problem between the hull and the buoycone were investigated in the environmental condition once in 200 years. A feasible numerical simulation method was found to determine the effectiveness of the single point of static seal at work , and to reach the feasible transformation scheme if a risk of failure was found .
