This paper presents the results of the numerical analysis on the behaviour of mooring system of offshore guyed tower. Finite element method is used and geometric nonlinearities are considered in the analysis of mooring line. The govering equilibrium equations are derived by the principle of virtual work, and modified Newton-Raphson method and Newmark-β method are employed in response calculations. The drag and inertia effects of fluid are included using a Morrison type equation. Numerical examples demonstrate the validity and capability of the mathematical formulation.
