BEL-Float - Fatigue damage assessment and lifetime prediction of a FOWT platform subjected to multiple non-linear stochastic load sources

BEL-Float - Victor Rappe

Fatigue is one of the main damage mechanisms for offshore wind structures. In particular, floating offshore wind turbines are subjected to variable hydrodynamic, aerodynamic, and mooring line loads which, combined with a non-stationary platform, lead to complex and dynamic stress states, making detailed fatigue analyses difficult. The objective of this research topic in the context of the BEL-Float project is to develop numerical models to assess the fatigue loads, the (local) accumulation of fatigue damage, and ultimately to accurately predict the lifetime of the floater.
