Abstract:  In this paper, the hydrodynamic characteristics of floating drilling production storage offloading (FDPSO) are studied. The characteristics of vortexinduced motion are studied by the method of combining numerical simulation and model test considering the coupling between different degrees of freedom and the effect of the mooring system. Dynamic mesh technique and Reynoldsaveraged method combined with detached eddy simulation (DES) turbulence model for the NavierStokes equation have been applied to research the flow field characteristics and the threedimensional vortexinduced movement of platform. Simultaneously, in the State Key Laboratory of Ocean Engineering of Shanghai Jiao Tong University, a physical model zoomed with a scale of 1∶80 is used to carry out the experimental study, and the results of model test are compared with numerical simulation. In order to reveal internal mechanism of vortexinduced motion and provide a reference for the design of this type of FDPSO, this paper focuses on the research of time histories of streamwise and transverse motion, spectral characteristics and “lockin” phenomenon.
