An adaptive algorithm for on-line estimation of physical coefficients of a mooring-line systems in floating structures in viscous environment is presented. The procedure is useful for obtaining cable characteristics, which are needed in stability analysis and control system design for OE systems. It uses measurements of position and forces from on-board instrumentation. It is also able to track changes in the depth and to test for parameter consistency in order to confer the estimation robustness with respect to dynamic perturbations. It is based on nonlinear solvers, which can cope with transcendental functions of the model structure. Finally, basic case studies are analyzed.
