J. Kim Vandiver’s MIT research team works on Vortex-Induced Vibration (VIV) of marine risers. Results are used to improve the VIV response prediction program, SHEAR7. Current research topics include:

• Reducing excess conservatism in fatigue damage rate predictions by calibration with full-scale drilling riser response data
• Developing improved models of structural damping of umbilicals
• Apply AI Techniques to Flexible cylinder VIV response prediction
• Refine input parameters for SHEAR7, based on outcomes from the Stress Engineering Wellhead Fatigue JIP

This work is sponsored by the Office of Naval Research and the SHEAR7 JIP (Joint Industry Project). “The SHEAR7 JIP” group has sponsored Prof. Vandiver’s VIV research for over 15 years. The current members are BP, Chevron, Petrobras, Shell, Equinor, ExxonMobil, and TechnipFMC.

AMOG, as the distributor of the program, conducts ongoing software development to include not only improvements in the programs capabilities and interface, but also to incorporate the results of updated data from the research programme.
