水下设备的S型铺设安装技术

S-Lay Installation of Subsea Structure

在采用S型铺设安装海底管道的项目中,水下在线设备和管端设备通常采用S型铺设方法进行安装。水下生产设备的海上安装作为最为复杂的工况载荷之一,对其结构设计具有至关重要的影响。文章总结了水下设备S型铺设安装方式的特点,并重点介绍了安装过程的计算分析技术和软件。

In the projects which S-lay method is selected,subsea in-line structures and pipe line end structures are usually installed by S-lay installation method.Installation loads are critical for subsea structures design.This article described subsea structures S-lay installation method,and focused on the calculation and analysis technology and software of installation process.
