... and fatigue assessment can be reduced significantly with the framework. A comprehensive investigation of fatigue damage of mooring systems in a non-Gaussian stochastic wave is conducted with a deep-water semi-submersible platform. Numerical results show that the non-Gaussian stochastic wave can accelerate...
