Marine cables play an irreplaceable role in securing floating offshore structures. The mechanical properties of mooring cables during the mooring process are crucial for ensuring the stable operation of floating offshore structures. The mechanical properties of mooring cables are primarily influenced by their material characteristics, which are mainly reflected in three key parameters: Poisson's ratio, linear density, and elastic modulus. In light of this, this study, based on the specific marine environmental parameters of a certain sea area, discretizes the mooring cable into a lumped mass parameter model and utilizes a time-domain simulation model to analyze the dynamic response of the mooring cable in the time domain. This approach further explores the impact of different Poisson's ratios, linear densities, and elastic moduli on the mooring mechanical performance of the mooring cable. The simulation results indicate that, under the assumption of an infinitely large bulk modulus, changes in Poisson's ratio have a relatively minor impact on the mechanical performance of the mooring cable. As the linear density of the mooring cable increases, the mooring tension experienced by the cable correspondingly increases, and the spatial configuration of the cable also undergoes significant changes. Moreover, variations in the elastic modulus significantly affect the dynamic configuration and mooring mechanical performance of the mooring cable.
