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.
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.
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.
Fairing Shape: The Pros and Cons of Popular Fairing Geometries
Various fairing profiles such as the teardrop and U-shape suppress VIV in deepwater while providing low drag. Each has its own benefits.
