Ocean Breeze Energy GmbH & Co. KG is owner and operator of the windfarm, BARD Offshore 1 (BO1), approx. 100 km off the German North Sea Coast. This windfarm is made of 80 wind energy generators from the 5 megawatt class, which reaches a rated power capacity of 400 megawatts.
NDT inspections were performed and shall be performed on cross welded beams of the BARD1 Offshore wind park. These inspections are achieved with Total Focusing Method ultrasonic measurement (TFM) using Gekko system (developed by M2M Company). A consequent amount of acquisition files representing approximately 7 Km of measurement must be analyzed in a very short time, which is quite challenging.
In this framework, specific improvements in the CIVA Analysis software were performed in order to make this work as automatic as possible in order to obtain a classification of the indications in weld seams and an automatic generation of indication tables presenting all the relevant information chosen by the user.
This article aims at presenting the specific developments that were achieved on CIVA UT Analysis software and the results of the automatic analysis and weld indications classification.
