A frequency domain analysis algorithm for predicting variance of quasi-static and dynamic wave-driven loads on a monopile-supported offshore wind turbine

Abstract

The purpose of this work is to develop and validate a frequency domain analysis (FDA) algorithm to predict loads on a monopile-supported offshore wind turbine (OWT). FDA is faster than the time domain simulations that are conventionally used to perform structural analyses of OWTs. An FDA algorithm that could accurately predict loads would enable expedient design and assessment of risk for OWTs. The current work presents an FDA algorithm for predicting variance of wave-driven loads during the non-operational condition with validation from both simulated and measured data.
