The work presents expressions to deal with the stiffness nonlinearity of polyester mooring cables. The study is based on two efforts. One basic effort is a comprehensive set of model cables tests performed. The other effort has been completed by the analysis of the acceptance tests performed with actual full-scale cables with 5-in (0.127-m) or thicker diameters. For the parallel construction cables under analysis here, a weak dependence on the frequency has been detected, while the mild to significant dependence on the average load and load amplitude has become clear. A theoretical consideration is made through the Maxwell model. Finally, suggestions on how to deal with the expression in a mooring design are also addressed.
