Abstract

See full text

A vortex-induced vibration (VIV) suppression system configured to accommodate a change in an underlying tubular diameter. The system including an encircling member dimensioned to at least partially encircle an underlying tubular. The encircling member may be, for example, a collar or a VIV suppression device such as a strake, or any other type of VIV suppression device. The system further including a band member dimensioned to encircle the encircling member and hold the encircling member around the underlying tubular at a desired axial position. A spring member may further be provided. The spring member may be positioned between the encircling member and the band member and dimensioned to contract in response to an increase in a diameter of the underlying tubular and expand in response to a decrease in a diameter of the underlying tubular such that the encircling member remains at the desired axial position.
