Smooth buoyancy system for reducing vortex induced vibration in subsea systems

摘要

Smooth buoyancy cylindrical elements having a surface roughness coefficient of K/D less than or equal to 1x10-4, 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.
