Mooring cable simulations with snap load capturing for wave energy applications
Paper in proceedings, 2016
In a number of experiments and field tests of point absorbers, snap loads have been identified to
cause damage on the mooring cables. Snap loads are basically propagating shock waves, which require special
care in the numerical modeling of the mooring cable dynamics. In this paper we present a mooring cable model
based on a conservative formulation, discretized using the Runge-Kutta discontinuous Galerkin method. The
numerical model is thus well suited for correctly capturing snap loads. The numerical model is verified and
validated using analytic and experimental data and the computed results are satisfactory.
