Abstract:
1. A fairing for the reduction of vortex-induced vibration, the minimization of drag and the elimination of the galloping phenomenon about a substantially cylindrical element immersed in a fluid medium, comprising: a one-piece fairing having a U-shaped cylindrical shell portion at a leading edge of the faring with opposing edges extending toward a trailing edge of the fairing, the opposing edges defining a longitudinal gap, wherein the gap provides an opening that allows for placement of the substantially cylindrical element through the gap and into the shell portion of the fairing; and parallel fins extending outwardly from the opposing edges of the shell portion in which the parallel fins taper inward, wherein the parallel fins are positioned so as to reduce vortex-induced vibration and minimize drag on the cylindrical element.
