Learning from our Mistakes: What the Lemnhult Wind Tower Collapse Can Teach Us About Fastener Fatigue Live Webinar Co-Produced by Industrial Fasteners Institute and Fastener Training Institute Date Friday, June 20, 2025 Time 11 a.m. - 1 p.m. CST /12 p.m. - 2 p.m. EST Instructor Laurence Claus, IFI Director of Education and Training COURSE DETAILS The adage “we can learn from our mistakes” is never truer than after a man-made catastrophe. Fortunately, given the critical nature of our fastener products, major accidents - with root cause that can be traced to the fastened joint - are relatively rare. When one does occur, smart professionals use the opportunity to learn what went wrong and devise ways to prevent it from happening again. On Thursday, December 24, 2015, Tower #15 in the Lemnhult Wind Farm near the Swedish city of Vetlanda collapsed between the first and second mast sections. This webinar will explore the details of the forensic investigation that followed and how emerging details of the construction process and service environment caused the flange bolts to fatigue and fail. In addition, this webinar will explore how the fatigue failure mechanism occurs in fasteners and relate it to factors that preceded it in this accident. This webinar is excellent for anyone wanting to learn more about fatigue in fasteners or gain appreciation for the criticality of good fastener design, installation and manufacturing practice.
