Optimierung des Managements der Tragwerksintegritätfür Offshore-Windenergieanlagen

This paper contains recent research results in the field of monitoring supported structural integrity management. Thestructural integrity management aims at ensuring the function-ing of a structure throughout the life cycle by compliance withthe target reliabilities. Building upon research results concern-ing the characteristics of monitoring techniques and data within the framework of reliability analyses, an approach is introduced for the optimisation of the expected structural integrity management costs by monitoring information. For thisaim, a life cycle cost benefit analysis for offshore wind turbinesupport structures is formulated. The optimal monitoring deci-sion parameters are then assessed utilizing the Bayesian pre-posterior decision theory. As a case study a monitoring systemfor a Multibrid M5000 offshore wind turbine prototype supportstructure is designed and possible reductions of the risks andexpected costs are quantified.
