摘要
从工程实际问题出发,利用实测资料,对渤海上的一个连接FPSO与固定导管架平台的动态悬跨缆进行基本的线型设计.借助Orcaflex软件对动态缆响应进行非线性时域分析,在不同海况下对动态缆进行极值分析和疲劳分析,进而对其进行安全评估,指出管缆的危险区域.结果对类似的悬跨缆设计、分析以及对其危险区域的保护等工作有实际参考意义.
Starting from the practical engineering problems, using the actual measurement data, the basic layout design is performed for a dynamic suspended umbilical connecting a FPSO located in Bohai Sea and a fixed jacket platform. The nonlinear time domain analysis is done on the response of the dynamic umbilical using Orcaflex software, the extreme condition and fatigue are analyzed on the dynamic umbilical under different sea conditions, and the safety is further assessed, by which the dangerous areas are pointed out. The results can provide practical reference for the design and analysis of the similar suspended umbilicals and the protection of its dangerous areas.
