In the current engineering practice, riser VIV design is typically based on empirically derived models. These tools have been under development for some time, but are based primarily on small scale rigid cylinder tests and flexible cylinders with relatively low aspect ratio. As high aspect ratio and full scale measurements become available for a wide variety of configurations, an improved understanding of the physics is beginning to emerge. This study employs a design based methodology for benchmarking VIV prediction tools against a comprehensive set of experiments. Configurations with bare, partially and fully straked risers operating at low and high current speeds are used to cover a broader range of validation conditions. Additional work to include the effect of high harmonics over a range of cases is necessary to draw more definitive conclusions. Given the difficulties in predicting VIV response for these small scale experiments the effectiveness in handling full scale risers is in question.
