Abstract:

Through the research of correlative flex pipe-laying technology at home and abroad, one kind design scheme of flex-lay system was put forward herein. Three-dimensional structure model of the system was established with Pro/E. By using the finite element method, the key parts strengths were checked. Dynamic simulation of the laying of the tower adjoining angle device was put up. Theoretical analysis and checking results indicate that the system can meet flex pipelines laying design and strength requirements.

Key words: flex-lay system, straightener, hang-off clamp, pipe-laying vessel

摘要：

通过对国内外软管铺设相关技术的分析研究,提出了一种柔性软管铺设系统的设计方案，利用Pro/E软件完成了软管铺设系统三维结构模型的装配。应用有限元计算方法校核了关键结构的强度，对铺设塔的角度调整液压缸进行了动力学仿真。理论分析和校核结果表明，该铺设系统的结构设计能够满足软管铺设的设计指标和强度要求。
