Abstract
Hydrodynamic damping, which is critical to the fatigue life estimation of water intake risers, remains unclear for low l(euleganCarpenter, say KC less than 5, flow regime. This thesis investigates the hydrodynamic damping of a riser with and without helical strakes at KC less than 5 experimentally and explores more appropriate hydrodynamic damping models at low KC. Models are proposed to simulate the hydrodynamic damping more accurately at this flow regime based on a series of experiments and numerical simulations. A framework based on the full-scale measurements is proposed to calculate the accumulated fatigue damage for risers in operation.
