Floating wind turbines are becoming more popular and is likely to be a major source of
energy in the future. These floating turbines relies on dynamic subsea power cables for
the transportation of electricity which are exposed to fatigue loading. It is desirable to be
able to model these power cable for e.g. lifetime predictions. This work focusses on the
conductor in the power cable. A FEM model was developed, and reversed bending was
simulated. The results were compared to laboratory tests of the same kind and shows
that the model overestimates fatigue life. This suggest that the fatigue damage process
might be induced by fretting. The study also discusses the influence of mean stress effect
and whether fretting is likely to occur based on a simplistic analysis.
