Abstract
Smooth buoyancy cylindrical elements having a surface roughness coefficient of K/D less than or equal to 1×10 , where K is the average peak-to-trough roughness and D is the effective outside diameter of said the cylindrical element are affixed about marine elements to decrease vortex induced vibration, thereby decreasing stress and loading on the marine elements.
