摘　　要：布放是浮标系统投入使用前的一个关键的作业过程。研究潜标系统布放过程中的水动力特性,对安全实现布放意义重大。考虑潜标系统各部分的水动力作用和系留索的弹性变形,通过Orcaflex时域模拟海洋潜标系统采用浮标先行投放法的布放过程,计算了潜标系统布放过程中的动态响应,并分析了波高、作业船速度和系留索弯曲刚度对布放的影响。所得结果对潜标系统的设计以及布放作业提供了一些可行的建议。It is significant to study the hydrodynamic characteristics of oceanographic subsurface buoy system during the process of deployment, which is a key procedure for the implementation of a safe deployment. Taking the flexibility of the mooring line and the effects of fluid inertia force into account, this paper simulates an anchor-last deployment for a subsurface buoy system and calculates the dynamic response of the system during the deployment based on Orcaflex. Additionally, the effects of wave height, speed of operation ship, and bending stiffness of mooring line are intensively examined via numerical simulation. The results provide some practical advices for the design and laying operation of subsurface buoy system.
