Tests conducted by Cornell and the U.S. Navy used new algorithms to outperform state-of-the-art programming for autonomous underwater sonar imaging, which significantly improved the speed and accuracy of identifying corrosion on ship hulls and other potential hazards.
With the increasing amount of high-voltage power line corridors, pipeline crossings, and transit systems, interference threats on pipeline assets are more common. This results in a higher risk of accelerated corrosion with poor notification to the pipeline operator.
Naval Research Laboratory Key West is a state-of-the-art testing facility for atmospheric and marine corrosion. A two-phase, multi-year severity assessment was recently conducted to compare 16 sites to Key West.
Petra has developed the first non-contact, thermal-drilling method that can uniquely bore 60-in (152.4-cm) diameter micro tunnels through hard rock, making it possible to bore utility tunnels through previously impenetrable geologies.
Since 2014, the MP Corrosion Innovation of the Year Awards program has provided a forum for innovative professionals to showcase their corrosion mitigation technologies and receive recognition for their solutions. Winners are selected by a diverse industry panel.
A research team at the Indian Institute of Technology Bombay has developed a new surface probe to measure the extent of corrosion in concrete rebar, which they say is more sensitive and accurate than conventional measurement techniques.
In the final column of this three-part series, longtime AMPP member Byron Evetts provides his perspective on the Champlain Towers South recovery efforts and wreckage in the days after the devastating collapse.
Tanya Brown-Giammanco, director of disaster and failure studies, explains NIST’s role in investigating structural disasters and why these probes can take years to complete.
Artisans at the Letterkenny Army Depot are now using cold spray technology to perform non-structural repairs, including repairs of corrosion and other surface defects. Cold spray offers additional repair benefits because of a lower operating temperature.
Charles S. Brown, PCS—deputy director of coatings at engineering, design, planning, and construction management firm Greenman-Pedersen, Inc.—offers a detailed checklist of safety and personal protective equipment (PPE) considerations when at a jobsite.
Viscoelastic coatings are able to instantly bond to surfaces without the need for much surface preparation, nor do they require preheating or curing time. Solutions can be tailored to specific problems by adding additional layers that provide extra protection, depending upon the need.
In part two of this three-part series, longtime AMPP member Byron Evetts provides his perspective on the Champlain Towers South recovery efforts and wreckage in the days after the devastating collapse.
There is growing concern that prestressing steel strands within post-tensioned tendons could experience hydrogen embrittlement. One proposed source of hydrogen is galvanic coupling that may exist between the galvanized steel duct and the steel strands.
Carbon fiber strands have a tensile strength comparable to steel, but they resist corrosion and require less maintenance over time. Longer service life is the major benefit, according to Michigan Department of Transportation officials.
More formalized than existing groups with moderators and formed under AMPP program committees, professionals can engage with those who share a common interest, demographic, or are from the same geographic area.
