Abstract: Abstract Triple helical strakes have been proved to be highly effective in suppressing the vortex-induced vibration (VIV) of isolated riser. Nevertheless, when risers work in clusters, interference effect can give rise to more complicated flow-induced… read more here.

DOI: 10.1016/j.oceaneng.2019.106439
Abstract: Abstract In order to study the helical strakes' suppression effects on the vibration riser, triangle and circular sections helical strakes are proposed. With the technology of dynamic mesh, forced oscillation in steady flow of the… read more here.
