Abstract:
1. A system for reducing vortex induced vibration (VIV) about a tubular, the system comprising: a strake section having a shell portion dimensioned to encircle an underlying tubular and a fin extending from the shell portion; a slot formed through the fin portion; a band member dimensioned for insertion through the slot and around the shell portion; and a resilient member positioned around the shell portion, the resilient member having discrete sections that are spaced apart and dimensioned to expand or contract in response to a change in diameter of the underlying tubular so that an axial alignment of the strake section about the underlying tubular is maintained, each of the discrete sections being positioned at an opening formed through the shell portion such that a portion of each of the discrete sections is exposed through the shell portion to an underlying tubular.
