Field observations revealed that a mooring buoy rapidly drifts in reciprocating motion along an arcuate path between two extreme positions. When the anchor point is considered origin and viewed from aerial perspective, this movement resembles pendulum. The implications of for data acquisition efficiency prompted our inquiry into phenomenon. comparative analysis model’s different movements under wave-only, current-only, wave–current conditions demonstrates currents are source inducing pendulum-like motion. To investigate mechanism current-driven motion, flow field around was visualized through numerical simulations. Specifically, CFD results aligned with confirmed periodic vortex shedding induces oscillatory forces, which dominate rapid movement. findings emphasize significant impact fluid viscosity resulting effects on characteristics buoys. They can provide foundation addressing more applied problems error-correcting trajectory predictions.
