The Sequential Reeling and Lateral Buckling Simulation of Pipe-in-Pipe Flowlines Using Finite Element Analysis for Deepwater Applications

This paper presents a sequential integrated reeling and lateral buckling PIP Finite Element Analysis (FEA), using ABAQUS, which captures the full reeling history, and is then included in the operational analysis for lateral buckling. The FEA model is sufficiently long that both the reeling and lateral buckling analysis can be carried out using the same model. This is particularly complex to undertake, due to convergence issues, but these issues have been addressed. Using this reeling module, results show that the effects of reeling should be taken into account for high temperature pipelines.
