This paper deals with numerical simulations of the mooring chain subjected to hydrodynamic forces due to wave motion. We developed an analytical model the mooring chain by using the finite segment method. From this analytical model, differential algebraic equations of the mooring chain are derived as a finite segment formulation. The dynamic behavior of the mooring chain is examined and discussed by the numerical simulation. The mooring chain shows various deformations by gravity and hydrodynamic forces, and it generated nonlinear characteristic. As a result, it is found that the dynamic behavior or the mooring chain by hydrodynamic forces influenced the magnitude of curvature. More, the dynamic behavior of the mooring chain is discussed by numerical simulations.
