The global loads and fatigue life of deepwater risers or riser bundles in current are often dominated by Vortex Induced Vibrations (VIV). Semi-empirical prediction program such as Shear7 and VIVARRAY are still the most commonly used tools for analyzing the VIV response of such systems. These programs rely on large databases with experimentally determined hydrodynamic coefficients.
