Vortex Induced Vibration (Viv) Suppression Apparatus And Method Of Installation

Abstract: A method for installing a vortex-induced vibration (VlV)-suppression assembly includes introducing a ViV-suppression device or apparatus to a tubular member above a surface of a body of water such that the tubular member is at least partially enveloped, introducing the unsecured VIV-suppression device or apparatus around the tubular member into the body of water, positioning the unsecured VIV-suppression device or apparatus along the riser length of the tubular member, and securing the unsecured VIV-suppression device or apparatus along the riser length of the tubular member. A loaded VIV-suppression device spool comprises one or more VIV-suppression device or apparatus having a unitary length in a range of from 12 meters (m) to 6,000 meters, comprised of an elastic polymeric material, and wrapped around a hub of the spool in an extended, ribbon-like configuration under tension.
