Abstract
A vortex-shedding mitigation assembly includes a jacket sufficiently flexible to lay substantially flat under its own weight and that is comprised of a woven, non-metallic material. The assembly further includes a fin row comprising a plurality of discrete fins protruding from the jacket and arrayed in series diagonally across the jacket such that, when the jacket is wrapped around a cylindrical structure, the fin row forms a helical strake having an axis substantially parallel to an axis of the cylindrical structure. The helical strake is operable to induce turbulence in a fluid flowing past the cylindrical structure, thereby reducing vibration of the cylindrical structure induced by vortex shedding from the fluid flow.
