Abstract

Abstract

Accurately assessing the motion and mooring load response characteristics of floating BeiDou beacons under complex sea conditions is crucial for addressing their operational reliability and the safety of the mooring system. This paper employed an AQWA-OrcaFlex coupled numerical simulation method to establish time-domain motion response models for lightweight and heavy beacon buoys. This model was preliminarily validated with experimental data from a moored box test, ensuring the reliability and rationality of the numerical simulation method and its results. Based on this, the statistical characteristics of the beacon’s surge, antenna freeboard, and mooring tension were systematically analyzed under typical sea conditions. Research indicates that wave height is the key factor dominating various beacon responses. Heavy beacons show significantly higher responses in all aspects than lightweight beacons, with the most intense responses occurring under high-wave height and long-period sea conditions. This study revealed the motion and load patterns of floating BeiDou beacons under different sea conditions, providing a reference for their structural optimization design and mooring system configuration.
