Abstract

In the harvesting of deep-sea wind energy, reliability-based design methods are of great significance to achieve rational design of floating offshore wind turbines that support reliable and economical wind energy harvesting. In this chapter, issues associated with the structural global reliability analysis of floating offshore wind turbines are discussed. Since the structure of floating offshore wind turbines is a high-dimensional nonlinear dynamical system, the analysis method in the time domain is of the main concern. Moreover, uncertainties involved in both environmental dynamic loads and the structure itself should be reasonably considered in the reliability analysis. Along this line, the simulation methods of random wind field and irregular waves using physically based approach and mathematical expansion-based approach are firstly presented. Advantages and deficiencies of different methods are discussed as well. Besides, special attentions are paid to the joint probabilistic modeling of multiple environmental variables to reasonably consider the combined wind and wave actions on floating offshore wind turbines. Then, the integrated dynamic modeling methods, which lay the foundation for the structural reliability assessment of floating offshore wind turbines, are outlined. The structural dynamics, the calculation methods of different loads, the servo system including pitch and torque controllers, and the electrico-mechanico-structure interactions, are all taken into account in the integrated dynamic modeling. The main structural reliability methods are revisited as well, with particular focus on the recently developed probability density evolution method, which can be used for the efficient reliability analysis of floating offshore wind turbines. An example of the structural global reliability analysis of a spar-type floating offshore wind turbine based on the probability density evolution method is presented to illustrate the reliability analysis framework of floating offshore wind turbines.
