Tail Fairings with FlexLock Technology

FlexLock™ fairings have been developed by VIV Solutions® and were first deployed on deepwater drilling risers in 2016.  The FlexLock design is significantly faster to install offshore than previous tail fairing™ designs and offers much better suppression and drag reduction than alternative buoyancy products.  Both standard and FlexLock fairing systems consist of tails that are held against a riser with straps and maintain their position along the riser using thrust collars.  However, unlike a standard tail fairing system, FlexLock offers ...

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 ...
