简介：Subseaflowline跳线开关(FJ)是为湿油树，subsea管道和起床人库的基本连接部件，起在subsea生产系统的一个不能替代的作用。在FJ的安装期间，碰撞经常发生在FJ和另外的设备之间，它可以引起严重损坏。作为操作的水深度增加，而且，对象鹤和绞车一样的安装设备的要求将增加。在中国的深海的FJ安装的研究仍然在主要阶段，因此为深海的FJ的一个安装方法在这篇论文被建议。一个典型M形状FJ安装系统的有限元素模型被造模仿安装过程。分析结果证明为FJ设计的安装步为深海的FJ可行、有效。为了保证安装的安全，处理，为FJ的碰撞敏感的分析被进行，并且结果证明设置在合适的价值的pickupspeed是必要的，以便在安装避免碰撞过程。而且，FJ的机械特征在环境条件的一个范围下面在安装期间被调查，FJ的最大的压力总是发生在它的中央位置，这被发现。为安装设备的基本要求也通过主要安装步的分析被获得。
