| 摘 要： | 对硬悬挂与软悬挂模式下超深水隔水管的轴向动力特性进行了研究，并探讨了隔水管的避台风撤离管理策略。研究表明，相对于硬悬挂模式，软悬挂模式更为安全可靠。推荐将隔水管软悬挂在钻井船上实施避台风撤离。如不具备软悬挂实施条件，部分回收隔水管并放任剩余部分硬悬挂在钻井船上实施撤离也是一种经济可行的方案。

| Abstract: | Axial dynamic characteristics of ultra-deepwater risers in hard and soft hang-off configurations are studied. And typhoon-avoidance management strategy of the riser is discussed. The research indicated that soft hang-off configuration is safer and more reliable than hard one. An evacuation strategy of hanging the riser off the vessel in soft configuration is recommended. If soft hang-off configuration can not be conducted, partly retrieved the riser and hanged the rest in hard configuration is also an economically feasible strategy. |
