Computational fluid dynamics are employed to simulate vortex-induced vibrations of risers. The current method uses a three dimensional model with an optimized mesh to analyze high aspect ratio risers. A riser with an aspect ratio in excess of 4,000 is modeled and compared with field experiments. Results show good agreement with experiments and the ability of the method to predict observed harmonic content. With the computational resources that can now be brought to bare, simulations of deepwater risers are possible for design validation and guidance of empirically based tools that currently do not model high harmonics.
