Abstract
Offshore Wind Energy Conversion Devices (OWECDs) are sensitive structures subjected to high force fluctuations making them prone to damage and present a challenge for in-situ structural identification due to the rough environment of offshore locations. Thus a remote identification and damage detection technique is required to keep track of any significant changes to the structural parameters of the OWECD. It is intended to present a structural identification and damage detection scheme using a Modified Adaptive Harmony Search coupled with a Modified Search Space Reduction Method (MAHS-MSSRM) to determine the structural stiffness of a damaged supporting structure of a numerically modeled OWECD based on its vibration response. The studied OWECD is an idling baseline 5-MW reference wind turbine developed by the National Renewable Energy Laboratory (NREL) identified under varying degrees of noise and different sensor configurations. The resulting identification accuracy and robustness were satisfying and encourage further investigation of the identification scheme with multiple damage locations, smaller damage values and unaligned inflow winds.
