Smar t III John Smar t Consulting Engineer High-Flying Tools of the Trade R ecently I received an email from the U.S. Maritime Administra- tion that shared a post by U.S. Secretary of Transportation Elaine Chao. In her post, Chao says, "Our infrastructure is the backbone of our economy, making it possible to move people, goods, services, and raw materials safely from our homes, factories, farms, and mines to and from destinations throughout our nation, and across the world." She continues that "…while our transportation infrastructure has given us unprecedented mobility for many years, it is increasingly in need of repair and refurbishment." When talking about U.S. infrastruc- ture, Chao refers to highways, bridges, tunnels, railways, airports, air traffic con- trol, seaports, mass transit systems, and pipelines. All of these structures, and other infrastructure around the globe, have a common thread—a need for the knowledge and expertise of the corrosion control industry to help owners and opera- tors identify corrosion issues and manage corrosion prevention. Fortunately, moni- toring and managing corrosion is not a static undertaking, but one that is dynamic and continually evolving as new technologies and methods are developed. Now, more than ever, tools are available that make it safer, faster, easier, more accurate, and more economical to imple- ment effective overall corrosion manage- ment practices: from monitoring metal structures and conducting inspections for signs of corrosion to testing corrosion- resistant materials, designing corrosion- resistant components, and identifying acceptable and unacceptable levels of corrosion. Several projects where companies are using unmanned aerial vehicles (UAVs) to inspect for corrosion are discussed in the feature article that starts on p. 28. These projects are combining UAVs and inspec- tion equipment to more accurately evalu- ate enclosed or difficult-to-access spaces for corrosion damage, such as those found on ships and marine structures. An integral part of any effective pipe- line integrity management system is online corrosion monitoring. The techni- cal article on p. 52 reviews various non - intrusive corrosion monitoring techniques such as ultrasonic testing, fiber-optic sen- sors, and electric field mapping. Nondestructive inspections are also being used by the U.S. Air Force to identify potential cracks in a variety of aircraft parts. This month, one of the Editor's Choice articles on materialsperformance. com describes the noninvasive inspection methods used by the 19th Maintenance Squadron at the Little Rock Air Force Base in Arkansas. Parts are dipped into a liquid f luorescent penetrant and viewed under black lighting, which illuminates cracks and corrosion and makes them easier to detect. There is no doubt that the inspection and monitoring technolog y available today is making it much more efficient to spot the degradation and corrosion that can attack our world's equipment and infrastructure. Armed with this modern arsenal of tools, corrosion professionals can point out the corrosion issues to own- ers and operators, advise them of the risks associated with the corrosion, and help them better manage their assets so that repair and refurbishment isn't an over- whelming assignment.
