Vortex-induced vibration (VIV) in deepwater marine riser systems is mitigated through a combination of design strategies and operational practices aimed at disrupting the formation of vortices and reducing the riser's susceptibility to vibration. VIV occurs when ocean currents flow around the riser, creating alternating vortices that shed from either side of the riser. These vortices induce oscillating forces on the riser, which can lead to significant vibrations and fatigue damage. One common mitigation strategy is to use VIV suppression devices, such as helical strakes or fairings. Helical strakes are long, continuous....
