Vortex-induced vibration (VIV) is one of the main reasons for failure of risers. Therefore, it is very important to predict the VIV behavior of risers by establishing an efficient model suitable for the field of ocean engineering. Based on the transfer matrix method for multibody systems (MSTMM), the main idea about simulating the vibration characteristics and fluid-structure interaction of a marine riser system is presented in this paper for the first time, using the MSTMM coupled with a Van der Pol model. The influence of different parameters, such as riser length, top tension, stream speed and steel joints, on the dynamic response of the riser is investigated.
