Inner Flow-Induced Buckling of Fiber-Reinforced Polymeric Catenary Risers

Production and deep-sea mining risers should have sufficient flexibility to avoid severe loading due to vessel motions. Free hanging catenary is the simplest and cheapest configuration because of the ease of installation and the minimal requirements for subsea infrastructure. The interaction of the inner flow with the moving riser dominates the dynamic stability of the system. In the present work, the motion equation for a long, multilayered,...
