12th International Conference on Applications of Statistics and Probability in Civil Engineering, ICASP12 Vancouver, Canada, July 12-15, 2015 1 Reliability Assessment of Wind Turbines John Dalsgaard Sørensen Dept. of Civil Engineering, Aalborg University, Aalborg, Denmark & DTU Wind Energy, Risø Campus, Denmark ABSTRACT: Wind turbines can be considered as structures that are in between civil engineering structures and machines since they consist of structural components and many electrical and machine components together with a control system. Furthermore, using a probabilistic design basis for reliability assessment it is possible to design wind turbines such that site-specific information on climate parameters can be included. Illustrative examples are presented considering uncertainty modeling, reliability assessment and reliability-based calibration of partial safety factors for structural wind turbine components exposed to extreme loads and fatigue loads. In traditional deterministic design based on design standards, the structural costs are among other things determined by the value of the partial safety factors, which reflects the 12th International Conference on Applications of Statistics and Probability in Civil Engineering, ICASP12 Vancouver, Canada, July 12-15, 2015 2 uncertainty related to the design parameters and the reliability level required.

Cyclic loads of variable amplitude resulting from wind speed variations and wave motion fluctuations referred to as stochastic loads coupled with environments containing chloride jeopardize the structural capability of OWT structures.29 To address the above challenges, this study aims to (a) develop a corrosion fatigue model based on pit and crack growth; (b) predict the nucleation/development and growth to critical size of the corrosion pits using data obtained from the literature; (c) predict pit to crack transition and crack propagation using the sequential steps of a high capability tool applying fracture mechanics functions and afterwards building stochastic parametric FEA model; (d) apply surrogate/meta model methods via artificial neural network (ANN) response surface method (RSM) to post-process the data in order to aid in expressing the limit state/performance function in terms of important stochastic variables; and (e) perform structural reliability assessment (SRA) that employs the generated limit state function (LSF) using widely recognized numerical reliability assessment techniques such as first-order reliability method (FORM) and Monte Carlo simulation (MCS).
