摘要： 以一座导管架平台实际安装为例，分别使用数值计算和模型试验的方法对浮托法安装进行了系统的研究.对整个浮托安装过程仔细剖析，选出具有代表性的工况，分别从频域和时域两方面分析.分析结果表明，数值计算与模型试验结果吻合良好，数值模拟方法具有较高的可靠性.在所考虑的海况条件下，驳船与上部模块运动符合要求，各种装置上受力均在允许范围内，可以进行安装作业.

Abstract: This paper investigated the floatover installation process on a jacket with numerical and experimental analysis. Numerical analyses in both frequency and time domain were carried out for typical configurations during floatover operation. Corresponding model tests were also performed in ocean engineering basin. The comparison between numerical and experimental results shows that the response amplitude operator and time series agree quite well. The barge has favorable hydrodynamic behavior in considered sea state and the loads of equipments are allowable. The floatover operation on the jacket is feasible.

Key words: floatover, jacket, offshore installation, topside
