Floating offshore wind turbines (FOWT) generate green renewable energy and are a vital part of the modern industry. Robust predicting extreme loads during FOWT operations is an important safety concern. Excessive structural bending moments may occur certain sea conditions, posing operational risk damage. This paper uses FAST code to analyze turbine due environmental acting on specific under actual local conditions. The work proposes unique Gaidai-Fu-Xing reliability approach that probably best suited for multi-dimensional responses have been simulated or measured over long period produce relatively large ergodic time series. In context numerical simulation, unlike existing approaches, novel methodology does not need re-start simulation again each system fails. As shown in this work, accurate forecast probability failure can be made using response. Furthermore, traditional techniques cannot effectively deal with dimensionality systems cross-correction across multiple dimensions. aims establish state-of-the-art method extracting essential information concerning through time-history data. Three key components analyzed, including blade-root out-of-plane moment, tower fore-aft mooring line tension. suggested study allows efficiently non-linear dynamic as whole.
