The objective purpose of the paper is explore the prediction the vortex-induced vibration (VIV) of a top-tensioned riser. The riser model is established based on vector form intrinsic finite element (VFIFE) method. The riser is discretized into a set of mass points whose motion follow the Newton’s second law and the central difference explicit integration method is used to solve the control equation of the mass point at each time. The fluid hydrodynamic forces are simulated by a Landl-modified Rayleigh wake oscillator. The calculation result is compared with the experiment result to validate the accuracy of the model. Time history of the axial displacement indicates that the model is a real three-dimensional model.
