This course deals with both Freespan pipeline and Riser vibrations, starting from introductory concept level discussion to more advanced hands-on calculations.
To provide trainees with good understanding of the phenomenon of VIV as well as the approach to estimate fatigue damage due to VIV.
• Concept behind Riser and Free span Vibration
- Physics behind VIV
- Fatigue due to VIV
- Pipeline and Riser VIV
- Flow Based Models, Force Based Models and Empirical Models
• Free Span VIV (Empirical Model)
- Free Span VIV Theory and Hand-Calculation (DNV RP F105)
- The trainees will work through 1 problem
- Assessment using FatFree exercise- hands on exercise
- Same problem as solved by hand; and
- More complex VIV example for use with FatFree
• Riser VIV (Force Based Models)
- Experiments and application
- Parameters that influence riser VIV
• CFD (Flow Based Model)
- Introduction and Application
Who should attend
The course is designed for engineers and managers interested in knowing more on the concepts of vibration. The course is applicable for new engineers as well as experienced engineers as the modules are set to include worked example problems.
