摘　　要：对防沉板式水下生产系统在ROV碰撞下的基础的承载力及其可靠性进行了分析。首先,分析了ROV碰撞载荷,得到了碰撞载荷下基础的水平和竖向承载能力。之后综合考虑了水平载荷和竖向载荷的衰减,建立了结构失效安全余量方程,并分析了系统的联合失效概率。算例表明,提出的方法是必要的和符合工程实际的。研究成果为考虑ROV碰撞对防尘板式水下生产系统中防尘板基础承载力分析提供了一个合理的方法。Considering ROV impact, Bearing capability and reliability of mudmat foundation of subsea production system are analyzed. First the ROV impact load is analyzed, and horizontal and vertical bearing capability of foundation under the impact load are gained. Where after, integration of the horizontal and vertical bearing capabilities are considered, safety margin equations are established, and failure probability is analyzed. Finally it can be seen through an example that the method in this paper is applicable and necessary topractical engineering project. A reasonable method for reliability analysis of mudmat foundation of subsea production system under ROV impact is provided.
