This paper presents a detailed finite-element analysis of unbounded flexible risers. The numerical results are compared to the analytical solutions. In the finite-element model, all layers are modeled separately with contact interfaces between each layer. The finite-element model includes the main features of the riser geometry with very little simplifying assumptions made. The numerical model was solved using a fully explicit time-integration scheme implemented in a parallel environment on a 12-processor cluster. The very good agreement found from numerical and experimental comparisons validates the use of our numerical model.
