摘　　要：随着现存海洋石油平台的服役期接近报废,海洋平台的拆除、回收和再利用等成为海洋工程领域新的技术挑战。相比于浮吊法拆除,浮托法拆除具有无需大型吊装船、作业周期短的优点,在海洋平台拆除项目受到重视并得以应用。本文对基于双体船的导管架平台浮托拆除过程进行了研究,通过建立双体船-上部组块系统动力学模型,并运用多体动力学软件对拆除作业过程进行仿真分析,仿真结果表明拆除作业过程中各举升臂作用具有良好的协调性,对上部组块运动起到了补偿作用,并揭示了作业过程中潜在的风险点。通过对导管架浮托拆除过程的分析,可以为评估浮托拆除作业的性能及保证拆除作业的安全性提供参考。As the service life of the existing offshore oil platforms has been close to the end of their operational period,the dismantling,recycling and reusing of the marine platforms become a new technical challenge in the field of offshore engineering.Compared with the float-crane removal,the float-over dismantling has the advantages of no need of large lifting vessels and short cycle of operation so that it has been attached importance to and applied in the offshore platform dismantling projects.In this paper,the float-over dismantling process of the jacket platform on a catamaran is investigated.And based on this,the dismantling process is simulated and analyzed by establishing a dynamical model for the catamaran-topside system as well as by using multi-body dynamics software.The results show that the lifting arms show a good coordination during the dismantling process and have played a compensatory role to the motion of the topsides.Additionally,the results have also revealed the potential risk points in the dismantling operation process.Through the analysis of the float-over dismantling operation process,references can be provided for evaluating the performance of the dismantling operation and ensuring its safety.
