Fastener Standards for Wind Energy Industry
2009
I have been following the Wind Energy Industry (Wind Turbine Manufactuaring) for several months now. Just two weeks ago a large convention (Wind Energy Convention) was held in Chicago and I know several fastener manufacturers attended. It is a HOT topic in manufacturing and should be of great interest to the fastener industry as millions of fasteners will be used in the manufacturing and installations of wind farms. A great source of information is the American Wind Engery Association www.awea.org and should be a good starting point for those interested in this business.
However, I have a question! Who is going to establish the fastener standards required for the Wind Turbine industry? Is it going to be inch standard or will the metric standards be established from the European companies working in this industry. Remember all automobiles are metric fasteners, while all airplanes are inch standard.
Do we start from the ground up and have the International Building Codes (IBC) set the standards for the anchor bolts and concrete requirements for installation? The rigging industry will have requirements for hoisting up the blades and setting them for installation. How about the contruction of the tower itself. Will it be structural bolts for strength and stainless steel fasteners or hot dipped galvanized fasteners to prevent corrosion? Is it an ANSI, ASTM, IFI or other fastener standard the fastener suppliers need to find out about and the fastener standard requirements? Do the engineers from the nearly 100 companies manufacturing wind turbines really know how to construct these towers in regards to what the wind speed and vibrations will do to fastener applications? How about lock nuts and special locking threads? It will be interesting to watch the growth of this industry in the next 10 years.
I was just wondering and would love to hear anybody’s thoughts. I will follow up in the future to see how fastener standards are being applied to the Wind Engery Industry.
