Vortex-Induced Vibration and Associated Fatigue in Marine Risers

Last updated on Feb 21, 2020

Goal: We are exploring the use of data-driven approaches that rely on measurements from field monitoring campaigns of deepwater drilling risers with a view to estimating fatigue damage and remaining life of risers that undergo vortex-induced vibration.
