To investigate the stability of an oscillating water column(OWC)perforated floating breakwater,the RAO(Response amplitude operator)for the motion of the floating breakwater was simulated using ANSYS AQWA software.The effects of several factors on breakwater stability were discussed including spacing between double-body structures of the breakwater,wave incident angle,width of OWC opening,draft depth,and length of anchor chain dragging.Results showed that the spacing change between double-body structures had little effect on mooring stabil-ity;an increase in wave incident angle led to reduce longitudinal sway motion amplitude and increase the stability;widening the OWC opening led to increased motion amplitude of the breakwater;increasing draft depth or reducing anchor chain length led to increase heave and roll direction motion amplitude while decreasing pitching direction motion and increasing natural period.The finding indicates that the mooring stability of OWC-perforated floating breakwater can be adjusted by changing the opening width,draft depth,length of anchor chain dragging,and wave direction in actual engineering.
