Based on the extreme living conditions and working conditions of the South China Sea which occur once in 100 years and once in 10 years,the damping device configuration of cylindrical FPSO with extension cylinder is designed and analyzed with the main consideration factors of heave motion inhibition performance.Based on JONSWAP wave spec-trum,the hydrodynamic analysis software AQWA based on three-dimensional potential flow theory was used to analyze the cylindrical FPSO with damping device of different configurations in time and frequency domain,and the safety of the de-signed mooring system was checked.Finally,the optimal damping device is selected by comprehensive analysis.The results show that damping device configuration Ⅰ(annular rectangular damping structure with gap)has better hydrodynamic per-formance and is the best structure form among the six damping devices.
