摘要

浮动软管是海上石油运输的关键部件。本文推导了单点系泊浮式管柱在波浪和水流荷载作用下的整体动力性能的数学模型。采用Airy波浪理论计算了浮管柱上的波浪力。采用弹性地基梁理论对浮筒、浮管柱和FSO的动力学进行了建模，并采用固定网格有限差分法对其进行了离散化。还考虑了法兰连接引起的弯曲刚度的不连续性。为了验证数学模型的准确性，使用Orcaflex软件工具建立了浮标、浮管柱和FSO作为一个系统的有限元模型。获得了在恶劣海况下浮动软管各段的位移和弯矩的数值结果。

Dynamic Response Analysis of Offshore Flaoting Hose Strings Under Wave Load

A floating hose is key item for offshore oil transportation. In this paper, a mathematical model is derived for the overall dynamic performance of a single point-moored floating hose string under wave and current load. Airy wave theory was selected to calculate the wave force on the floating hose string. The dynamics of buoy, floating hose string and FSO were modelled using elastic foundation beam theory and discretised by using a fixed grid finite difference method. Discontinuities in the bending stiffness due to the flange connections are also considered. To verify the accuracy of the mathematical model, the finite element model of the buoy, floating hose string and FSO as a system was established by use of Orcaflex software tool. Numerical results for the displacement and bending moment at each section of the floating hose under severe sea conditions were obtained.
