... Abstract Vortex induced vibrations (VIV) may be developed in the sag-bend area of steel catenary risers (SCRs) and lazy wave risers (SLWRs) induced by the top motions. There is lack of reliable tools to predict VIV responses in such oscillatory flow conditions in the riser design. A time-domain...

... by Aronsen (2007), the in-line VIV response of partially strake-covered pipeline spans is calculated. It is found that as little as 10% strake coverage at the optimal location effectively suppresses pure in-line VIV. Further advantages of strakes rather than intermediate supports to suppress in-line VIV...
