Abstract
The lumped-mass modelling is adopted in this paper for the dynamic analysis of a mooring cable. Since the condition of the seabed affects the motion of cable, the impact of seabed is divided into vertical and horizontal components in this paper. The seabed is simplified as plane and treated as spring modelling in vertical direction; meanwhile, the friction is applied on the cable resting on seabed in horizontal direction. Considering the environments, this paper also includes the tension and damping of cable, the hydrodynamic drag forces and the effect of added-mass during building the formulation of cable modelling. Finally, this numerical modelling is verified with commercial simulation code ProteusDS.
