Abstract
An improved strake for structures that are subject to vortex induced vibrations and motions due to fluid flow around the structure. One embodiment includes a streamliner on the edge of the strake. The streamliner may be added to existing strakes or may be formed at the same time as the strake for extruded strakes. The streamliner reduces vortex induced vibrations and motions of the structure to which the strake is attached. Another embodiment of the invention provides a tension resisting support attached to the strake and structure. The support provides a different load path along the strake than the previously known art for carrying the pressure loading from fluid pressure acting normal to the surface of the strake.
