Vortex-Induced Vibration Analysis (VIVA) Based on Hydrodynamic Databases
We outline the procedures used by program VIVA, developed over the last sixteen years to estimate the cross-flow vibration of marine risers in arbitrary currents. The program theory is based on a combination of first principles, extensive hydrodynamic databases, as well as modifications introduced t...
