  • Résumé

  • Satisfy your curiosity and learn how some of our country’s smartest engineers and scientists are solving many of the toughest challenges facing the nation and the Warfighter. The U.S. Army Engineer Research and Development Center (ERDC) is comprised of seven research laboratories across four states, and one of its greatest strengths is its ability to combine the expertise from multiple laboratories into powerful, cross-disciplinary projects. Each month, we dive into one of these complex problems across its broad civil works and military mission space and ask ERDC’s world-class researchers about how they are discovering, developing and delivering practical cutting-edge solutions that make the world safer and better.

  • #30: Oil on Ice: Improving spill response in frigid regions

    #30: Oil on Ice: Improving spill response in frigid regions
    Oct 11 2024
    The environmental and economic toll of large-scale oil spills, such as the Exxon Valdez and Deepwater Horizon incidents, can linger for decades. That’s why research into better techniques and technologies for rapidly responding to these disasters is critical. One aspect of oil spill response that requires particular attention is the effect of ice and frigid temperatures, which can change oil properties and make the substance more difficult to locate or extract. Through the world-class expertise and facilities at its Cold Regions Research and Engineering Laboratory (CRREL), ERDC has developed a unique capability to enable in-depth research into mitigating oil spills on ice. As ERDC collaborates with partners to find these innovative solutions, first responders will be better equipped to have the greatest impact should a disaster occur. We discuss ERDC’s oil-on-ice research with Kate Trubac, a research general engineer at CRREL. We talk with Kate about the challenges of oil spill cleanup (3:34), how icy conditions make it even more difficult (4:26), and why it is important to study this topic (6:27). We also discuss ERDC’s role in this research (9:30, 10:52), how it supports a variety of strategies (18:01), its collaboration with partners (9:49), and what the future holds (35:12).

  • #29: Underkeel Clearance: Quantifying demand for USACE dredging

    #29: Underkeel Clearance: Quantifying demand for USACE dredging
    Jul 31 2024
    The ships calling upon U.S. ports have grown larger, and navigation channels must be dredged to greater depths to handle them. However, dredging is expensive, and the U.S. Army Corps of Engineers (USACE) needs more data-driven tools to prioritize limited resources more efficiently. Responding to this need, ERDC developed Underkeel Clearance. Applying newly available ship location data and combining it with other data points, this metric directly measures how often ship keels approach the bottom of a channel. By analyzing how ships are using the dredging USACE already provides and highlighting the areas with the highest volume of ships with limited clearance, Underkeel Clearance gives USACE waterway managers new insight to better quantify channel maintenance requirements. The project falls under the USACE Coastal Inlets Research Program. We discuss Underkeel Clearance with Dr. David Young and Dr. Brandan Scully, research civil engineers at ERDC’s Coastal and Hydraulics Laboratory. Topics include how dredging decisions have traditionally been made (3:07), how Underkeel Clearance can improve this methodology (5:33) and surprises that have emerged as researchers began analyzing Underkeel Clearance data (14:46). We also talk about how this tool could change USACE dredging operations (17:23), other use cases of this data (21:32) and what the future holds for the effort (33:47).

  • #28: Advanced manufacturing: Using 3D printing, new materials and optimized designs to produce large-scale components

    #28: Advanced manufacturing: Using 3D printing, new materials and optimized designs to produce large-scale components
    May 1 2024
    As America’s civil works infrastructure facilities age beyond their initial design lives, so do the thousands of individual components that keep them functioning. These original components were often fabricated using vintage material and manufacturing methods, making them costly, burdensome and time-consuming to replicate. However, if one of these parts were to suddenly break, that failure could shut down a facility for months, causing significant national economic damage. Faced with this challenge, the U.S. Army Engineer Research and Development Center (ERDC) is studying how innovative techniques, such as additive manufacturing (large-scale 3D printing), advanced materials and design optimization can be used to replace vintage infrastructure components faster and at a lower cost while maintaining, and even improving, their properties. This research resulted in a recent collaboration with the USACE Detroit District and Lincoln Electric to manufacture the largest U.S. civil works infrastructure component produced by a 3D printer – a 12-foot-long, 6,000-pound metal part for the ship arrestor system on the Poe Lock, one of two active locks on the Soo Locks facility. We discuss ERDC’s advanced manufacturing research with Dr. Robert Moser and Dr. Zack McClelland from ERDC’s Geotechnical and Structures Laboratory. Moser is a Senior Scientific Technical Manager for Materials, Manufacturing and Structures, and McClelland is a research mechanical engineer. We talk about the existing state of aging infrastructure and the role additive manufacturing can play to meet this challenge (3:49), how ERDC became involved in 3D printing and how that capability has evolved (7:09), ERDC’s focus areas for advanced manufacturing R&D (11:36), and the project to manufacture the largest U.S. civil works infrastructure component produced by a 3D printer (18:40). We also discuss how ERDC is working to overcome some of the challenges of 3D-printing large infrastructure components (25:27), how ERDC’s high-performance computing capability boosts this effort (28:49), how it has benefitted from military research (39:02) and what the future holds (49:11).
