SHM systems and the related non-destructive test and evaluation methods are discussed in this review. As many of the methods function on local damage.
[15] Different strategies and different methods have been investigated for the application of SHM systems to the OWTs. Usually, these studies focus on one specific component of the OWTs. Because of the complex topology of the OWTs and the complex loads caused by wind and wave, most of the current existing SHM systems do not concentrate on monitoring 3-dimensional full-field displacements and stresses of the OWTs. For the purpose of fulfilling this request, iFEM, developed by Tessler and Spangler [16-18], can be used as the state-of-the-art methodology for the SHM system of the OWTs. iFEM uses the strain data obtained by sensors to numerically restore the displacements, strains, and stresses of the structure in real-time.

# Finite element analysis of offshore wind turbines. A TWI Industrial Member client was interested in developing a structural monitoring system for wind turbine structures. Finite element analysis was used to simulate the change of response of the wind turbine structure with and without defects. In compliance with TWI's confidentiality policy, the results and conclusions of this work remain client confidential. However it was able to conclude that the finite element model of the wind tower could be used to predict the effect of various damage mechanisms on the structural response of the tower under wind and wave loading. The final report was able to inform its client about on the feasibility of these potential new condition monitoring systems which would allow the structural response of offshore wind turbine towers to be understood.
