海上采油立管的随机波浪响应

The Response of off-Shore Oil Gathering Vertical Pipe to Random Waves

  • 摘要: 本文应用线性波理论,通过波浪迭加法,探讨了海洋平台油气生产立管系统的动力性质。应用线性化的Morison方程计算作用于立管的波浪力,包括随机波和规则波两种情况。有限元方程的求解是通过模式迭加方法在时域内进行的。分析了波力单独作用及由波力和平台位移共同作用下立管的两种动力响应情况。介绍并比较了所得到的数值结果,包括位移、扭矩和弯矩等数据。结果表明,本文所提出的分析方法是可行的,而计算机程序则可为立管的强度设计提供方便。

     

    Abstract: In light of linear wave theory, the article explores the dynamic properties of the oil and gas production vertical pipe system on off-shore platform by means of wave repetition. Morrison equation for linearization is used to calculate the wave force exerted on the vertical pipes. The solution of the finite element equation is carried out within the time range through mode repetition. Here is analysed the two dynamic responses on the part of the vertical pipes to the single wave force and the combined forces of it and the displacement of platforms. It explains and compares the values thus obtained such as the data of displacement, torque and bending torque. The results show that the analytical method presented inthis article is practical, and the computer programme can facilitate the strength desigh of such verticle pipes.
