The prediction and control of vortex-induced vibration (VIV) is one of the key problems for riser design. The effect of platform heave motion on VIV of deep sea top-tensioned riser (TTR) is presented by means of numerical simulation and experiment in this research. First. the heave motion was modeled as a parametric excitation. https://www.markbroyard.com/mega-pick-michigan-state-spartans-secchia-stadium-on-sale-super-sale/
