Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Stacks, chimneys, and cylindrical offshore structures commonly utilize helical strakes to successfully disrupt wake formations and suppress vortex-induced vibrations.

The analysis

The claim is specific, empirical, and directly tested in fluid dynamics literature. Retrieved papers such as [3] and [7] confirm that helical strakes are effective at suppressing vortex-induced vibrations on cylindrical structures like stacks and risers, and no papers contradict this relationship.
