Mooring systems made of synthetic fiber ropes, in particular polyester ones, have gained prominence in recent decades. However, the mechanical behavior of such fibers has its complexities for simulation due to viscoelasticity and material and geometric nonlinearities. Numerical simulations of the mechanical behavior of the material used in the anchoring system are performed based on the viscoelastic theory and, for that, experimental data are used to calibrate the model. The viscoelastic mathematical approach of numerical simulation depends on the strain energy function which, for multifilaments of polymeric materials, has characteristics such as viscoelasticity and incompressibility. The objective of this study is to study different strain energy models applied to the numerical simulation of polyester, a material used in offshore anchorages. As a result, a quantitative comparison is obtained between the models regarding the quality of the mathematical adjustments.
