摘要
为提高海洋设施的安全性,进行导管架船撞损伤与剩余强度研究。综合考虑船撞导管架过程中所涉及的材料、尺寸、碰撞等情况,运用有限元软件Abaqus对多种工况下船撞导管架的过程进行数值模拟,深入探讨不同船舶初速度下导管架剩余强度的变化情况,分析导管架不同部位之间的剩余强度差异,论证最大碰撞力与各撞击因素的关系,实现导管架撞击后的剩余强度评估。
In order to improve the safety of offshore facilities, the jacket damage by ship collision and residual strength are studied. The materials, dimensions and collisions involved in the process of ship collision with the jacket are comprehensively considered.The finite element software Abaqus is used to simulate the process of ship collision with the jacket under various conditions. The change of the residual strength of the jacket under different initial speeds of ships is further discussed.The difference in residual strength between different parts of the jacket is analyzed. The relationship between the maximum impact force and each impact factor is demonstrated and the residual strength evaluation after the impact of the jacket is realized.
