This paper focuses on the analysis and optimization of ultimate safety conditions for ship mooring, establishing a numerical simulation framework through ship six-degree-of-freedom motion models, environmental load models (including wind, waves, and currents), and mooring line tension calculation methods to evaluate the reliability and stability of ship mooring systems under extreme conditions. Based on the OCIMF Mooring Equipment Guidelines (MEG4) standard, ship maneuvering simulators were employed for numerical simulation of ship mooring, with tests conducted under the most adverse working conditions. Results show that the peak surge-sway displacement of the ship exceeds 1.5 m, and the maximum mooring line tension surpasses its safe load capacity.

摘要

This paper focuses on the analysis and optimization of ultimate safety conditions for ship mooring, establishing a numerical simulation framework through ship six-degree-of-freedom motion models, environmental load models (including wind, waves, and currents), and mooring line tension calculation methods to evaluate the reliability and stability of ship mooring systems under extreme conditions. Based on the OCIMF Mooring Equipment Guidelines (MEG4) standard, ship maneuvering simulators were employed for numerical simulation of ship mooring, with tests conducted under the most adverse working conditions. Results show that the peak surge-sway displacement of the ship exceeds 1.5 m, and the maximum mooring line tension surpasses its safe load capacity.
