Our engineers have authored various technical notes on complex issues related to vortex-induced vibration (VIV).  These notes are intended to provide a higher level of insight and detail on their respective subject matters.  Please refer to the list below and click on any file to download the PDF.

Managing Marine Growth

Anti-fouling coatings and/or subsea cleaning operations can significantly improve the performance of suppression devices in regions prone to excessive marine growth.


Alternative Buoyancy Systems for Deepwater Drilling

Buoyancy systems with unique surface profiles offer minimal improvements for VIV and drag reduction when compared to devices like fairings.  


Helical Strakes: Coverage Length and Density Considerations

VIV suppression benefits can be optimized by pre-determining the amount and location of strakes prior to installation.


Fairings: Coverage Length and Density Considerations

Determining the best location and layout of fairings on a tubular can help minimize cost while still achieving desired performance requirements.


Fins Do Not Need to be Aligned to Adjacent Strakes

Helical Strakes: Fin Alignment

VIV Solutions’ strakes do not require alignment of adjacent fin sections from one strake body to the next, which helps save valuable time offshore during installation.
