Abstract EN
In offshore oil and gas engineering the pipeline abandonment and recovery is unavoidable and its mechanical analysis is necessary and important.
For this problem a third-order differential equation is used as the governing equation in this paper, rather than the traditional second-order one.
The mathematical model of pipeline abandonment and recovery is a moving boundary value problem, which means that it is hard to determine the length of the suspended pipeline segment.
A novel technique for the handling of the moving boundary condition is proposed, which can tackle the moving boundary condition without contact analysis.
Based on a traditional numerical method, the problem is solved directly by the proposed technique.
The results of the presented method are in good agreement with the results of the traditional finite element method coupled with contact analysis.
Finally, an approximate formula for quick calculation of the suspended pipeline length is proposed based on Buckingham’s Pi-theorem and mathematical fitting.
