Abstract ：The buoy sinking m echanism of the inner turret-type single-point m ooring system is analyzed, an d the buoy sinking probability is calculated. The hydrodynam ic m odel of
Floating Production Storage an d Offloading (FPSO) an d its m ooring system is established,
the coupled sim ulation in tim e dom ain is carried out, an d the m ooring line tension is solved.
Based on the tim e course of the m ooring line tension in the horizontal an d vertical directions,
the vertical loads of buoy a re calculated. Com bined with statistical knowledge an d reliability of
knowledge, the probability of the buoy sinking under different pre-tightening forces is solved.
At the sam e time, the influence of m ooring hole location on buoy sinking is considered, an d
the corresponding m easures to reduce buoy sinking risk is proposed.
Key words：inner turret；single-point m ooring system；buoy sinking
