Andreas Echtermeyer
Background and activities
Andreas Echtermeyer Andreas Echtermeyer is Professor for composites and polymers in the Department of Engineering Design and Materials at the Norwegian University of Science and Technology (NTNU) Trondheim. He joined the university full time in 2008 after having been an adjunct professor since 2003. Previously he worked for Det Norske Veritas (DNV) as senior principal engineer in the section “Structural Integrity and Laboratories” and was responsible for composites and polymers in offshore applications. He continues to be a consultant for DNV. He received his PhD in Materials Engineering from the Massachusetts Institute of Technology and his Diploma in Physics from the Technical University of Munich.
He has 18 years of industry experience with composite applications. He is author or co-author of more than 50 articles and more than 200 technical reports. He was the main contributor and responsible for the development of DNV’s offshore standards for composites offshore and composite risers. He was further heavily involved in the development of the rules for Compressed Natural Gas (CNG) composite pressure vessels for ships, of the ISO standard update for umbilicals and guidelines for adhesive joint technology for repair of metal structures and of the Recommended Practice for Qualification of New Technology. He has been project manager or responsible of many national and international research projects as well as industrial development projects.
