摘要
相较于传统的吊装法,浮托安装法是目前一种比较安全、经济、可靠的大型组块海上安装方法。本文对某平台上部组块的海上浮托安装进行了数值模拟,应用ANSYS-AQWA软件建立上部组块-驳船-系泊系统模型,在时域内对模型就位状态下的运动响应进行了耦合动力分析。重点研究了不同波浪工况下上部组块-驳船-系泊系统模型关键点的运动以及系泊张力的变化情况。研究结果对实际工程中应用浮托安装法施工具有重要的参考意义。
Floatover is a safe, reliable and economic offshore installation method comparing with tradi-tional lifting methods. Numerical simulation was conducted to investigate the {loatover installation of an offshore platform. The topside-barge-mooring system coupled dynamic system was modelled using AN- SYS-AQWA. And coupled dynamic analysis was performed to study the motion response in the time do-main under docking situation. Particular attention is paid on the motion of some key points and mooring tension of the dynamic system. The research results have an important reference value in practical floatover project.
