Marcollo, H., and Vandiver, J.K., Paper number OMAE 2009-80028, Proceedings of the ASME 2009 28th International Conference on Ocean, Offshore and Arctic Engineering (OMAE 2009), May 31 - June 5, Honolulu, Hawaii, USA, 2009.


A VIV benchmarking study was undertaken using SHEAR7v4.5 against NDP high mode VIV response laboratory data. The purpose of which was to derive an improved set of modeling parameters for partial strake coverage cases whilst not comprising previous accuracy of shear flow bare riser response predictions. Fifty percent (50%) partial strake coverage experimental data was utilized from both uniform and shear flow conditions while bare data was also included in the activity for reference purposes. The results showed that such an activity can derive an improved set of modeling parameters that significantly improve the ability to match experimental results and also highlight where future improvement efforts can be targeted.
