VIV Solutions’ SHEAR7 Report

SHEAR7 is the offshore industry’s leading tool for conducting vortex-induced vibration (VIV) analyses of deepwater risers and pipelines. Helical strakes and fairings are often installed on subsea structures to suppress VIV and mitigate the long-term effects of harsh environmental conditions, thereby lengthening the fatigue life ensuring safe operations.

As such, VIV Solutions® has developed a new set of input coefficients that better match data measured during controlled laboratory experiments than the default SHEAR7 coefficients.  Our calibration exercise is intended to produce ...

Technical Note on Fairing Shape

Download our new Technical Note titled Fairing Shape: The Pros and Cons of Popular Fairing Geometries.  Readers will learn about the V- and Y-shape teardrop profile, as well as U-shapes and long chord fairings.  It is important to design fairings properly to achieve low drag. Engineers must account for parameters such as body deformation which can occur under extreme current loading conditions and change the chord-to-thickness ratio of the device.  Other critical elements such as ...
