Partial helical strake system for vortex-induced-vibration suppression

摘要

A partial helical strake system (10) for suppressing vortex induced vibration in a cylindrical structure deployed in a marine application is provided. The system comprises a base (12) connected to the cylindrical structure (11), and at least one helical strake projection (14) from the base for a part of the circumference of the cylindrical structure.
