Small fixed teardrop fairings for vortex induced vibration suppression

摘要

A non-rotatable fairing for suppression of vortex-induced vibration of a marine tubular is provided, the tubular having a circular cross section and a centerline that is normal to the circular cross section, the fairing comprising: shaped sides that extend essentially tangentially from the outer surface of the tubular toward a point that is about a distance equal to the outside diameter of the tubular or less from the centerline of the tubular; and a means to fix the fairing to the tubular so that the fairing cannot rotate around the tubular, wherein the maximum length of the cross section of the combined fairing and tubular is between about 1.25 and about 1.5 times the outside diameter of the tubular.
