Hydrodynamic forces acting on mooring lines are essential in the case of a slow drift oscillation of a floating structure, because drag forces acting on mooring lines act as the damping force and have a great effect on the slow drift oscillation. In this paper a time domain Modified Approximate Method for calculating the dynamic tension of mooring chain is presented. The calculated results of the slow drift oscillation of floating structure and dynamic tensions of mooring lines obtained by using this method are compared with the experimental ones. The calculated results are in good agreement with experimental ones.
