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 ...

Deepwater VIV Analysis

Analysis of vortex-induced vibration (VIV) is an important component of the overall analysis of any tubular or bluff structure exposed to air or ocean currents.  These days, it is common to see VIV analyses of various risers, tendons, pipelines, and structures in wind performed by novice analysts.  This is concerning since the analyst may lack the ability to discern if the numbers output from a computational model are anywhere close to what would be expected in an experiment ...
