摘要
本文针对渤海油田浅水FPSO软刚臂单点系泊系统，利用多刚体动力学的分析方法，建立软刚臂系泊系统动力方程进行受力分析，得到FPSO在风浪流中运动时转塔上的系泊力，并与模型试验实测得到的系泊力进行对比，以验证动力方程与计算程序的正确性。二者对比的结果吻合良好，动力分析方法正确，故可应用于对系泊系统的模拟和对FPSO运动中系泊系统的受力预测。
In china, there are some FPSOs using tower-yoke mooring system in shallow water in Bohai Bay. By means of multi-rigid body analysis method, the tower-yoke FPSO mooring system is studied. The dynamic equation of the tower yoke mooring system is established, then the static and dynamic restoring forces of the tower-yoke system are analyzed and calculated. The numerical results agree well with model test values. It is shown that multi-rigid body analysis method is capable and accurate to predict the mooring force of the tower-yoke mooring system of large FPSO in shallow water.
