Developments in Riser Vortex Induced Vibration Analysis Event: Developments in Riser Vortex Induced Vibration Analysis Date: June 1998 Author: J. Bowman, H. Howells Cross-flow vibration of risers in steady current flow is an important factor in the design of all rigid riser systems for deep water, including drilling, production and export risers. High levels of VIV fatigue damage can be accumulated in relatively short periods of time in the severe currents encountered in most of the deep water development areas worldwide. Suppression devices, such as helical strakes or fairings may be needed to prevent unacceptable levels of fatigue damage. These devices can have a significant influence on riser cost both in terms of materials and installation time. Reliable predictions of VIV response are needed to ensure that premature failures do not occur and that undue expense in specification of suppression devices is not incurred. A considerable amount of experimental work and analytical development has been conducted in recent years to improve predictions of VIV response. This paper gives a designer’s perspective of the available methods for VIV analysis, current developments and the requirements for further work to rationalise riser design for VIV’s.
