Reducing the deleterious effect of Vortex Induced Vibrations (VIV) in marine risers is an
important task for ocean engineers; and many competing factors exist in the design of
VIV suppression devices. This thesis explores the experimental minimization of the drag
force and the disruption of v0l1ex formation by utilizing VIV suppression devices.
Two series of tests are conducted-both utilizing separate testing designs. The first tests
are the flexible cylinder experiments, detailed in Chapter 2, which determine the drag
force and vibration amplitude of numerous, original testing configurations. The second
series of tests are the rigid cylinder, PIV experiments, detailed in Chapter 3. These tests
measure both the drag force on the cylinder and the oscillating component of the lift
force, the latter of which is a good indication of v011ex formation. The Chapter 3 tests
also image the test section wake-providing helpful insight into the physical process of
vortex formation.
In brief, this thesis presents a detailed description and results of the two series of original
VIV suppression tests. Many original configurations are tested, and the results are
contained herein.
