Hydrodynamics Study of Riser with Helical Strakes Oscillating in Flow

open access: yesShanghai Jiaotong Daxue xuebao, 2021
To reduce the vibration damage to the riser, hydrodynamic parameters of a smooth riser and a riser with triple symmetrically distributed helical strakes are evaluated in an experiment. The wave and current in natural environment are conceptualized to the
