    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; anda 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.

    摘要： A method to reduce vortex-induced vibrations in subsea risers is provided wherein a flexible fairing is provided surrounding the riser. The flexible fairing will reduce displacements caused by vortex induced vibrations regardless of the direction of the current and will be tolerant of marine life growth.
