Uncertainties Regarding VIV in the Design of Deepwater Risers Event: Uncertainties Regarding VIV in the Design of Deepwater Risers Date: June 1998 Author: S. Hatton, N. Willis Exploration and production in the Gulf of Mexico and West Africa is moving into water depths of over 2000m, and in the harsher areas of West of Shetland and Voring Basin, depths of over 1000m are being considered. The increased water depth and severe currents experienced in most of these areas place more severe design requirements on riser systems. A key aspect is Vortex Induced Vibration (VIV), which can lead to high frequency cyclic stresses, resulting in high rates of fatigue damage. This effect is important for drilling risers, and even more so for production risers where service lives in excess of 25 years are often required.
