Five sled configurations with varying anode spacing were tested on submerged gates to assess performance. Nearly all sleds met the AMPP 100 mV polarization criterion within one day, confirming effective corrosion mitigation. However, sleds with widely spaced anodes (1\\u00d75 Long and Medium) significantly outperformed tightly grouped designs (Short, Stacked), delivering higher current output and sustained polarization. The modular sleds were easy to install, required no structural modifications, and allowed for surface-level maintenance. Results confirm that anode spacing is critical to minimizing interference and maximizing CP efficiency. Modular sleds offer a practical, retrievable alternative to traditional CP systems, especially where dewatering is impractical. Design recommendations include optimizing anode layout, ensuring robust electrical connections, and implementing routine monitoring. These findings support broader adoption of sled-based CP systems across Reclamation infrastructure.\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://data.usbr.gov/catalog/8514/item/133835\", \"description\": \"Landing page for \\\"S&T Project 22060 Final Report: Modular Anode Sled Development and Testing for Cathodic Protection of Immersed Steel Structures\\\"\", \"mediaType\": \"text/html\", \"title\": \"RISE Item Details Page URL for \\\"S&T Project 22060 Final Report: Modular Anode Sled Development and Testing for Cathodic Protection of Immersed Steel Structures\\\"\"}, {\"@type\": \"dcat:Distribution\", \"description\": \"\\\"S&T Project 22060 Final Report: Modular Anode Sled Development and Testing for Cathodic Protection of Immersed Steel Structures\\\" as a PDF file\", \"downloadURL\": \"https://data.usbr.gov/rise/content-rise-public/rise/catalog-item/binary/S&T Report 22060_508.pdf\", \"mediaType\": \"application/pdf\", \"title\": \"PDF File for \\\"S&T Project 22060 Final Report: Modular Anode Sled Development and Testing for Cathodic Protection of Immersed Steel Structures\\\"\"}], \"identifier\": \"https://datainventory.usbr.gov/rise/item/133835\", \"keyword\": [\"Cathodic Protection\", \"Galvanic Cathodic Protection\"], \"landingPage\": \"https://data.usbr.gov/catalog/8514/item/133835\", \"modified\": \"2025-10-15T15:12:47Z\", \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"Bureau of Reclamation\"}, \"spatial\": \"{\\\"type\\\":\\\"Polygon\\\",\\\"coordinates\\\":[[[-124.508,48.197],[-124.304,40.096],[-117.02,32.608],[-103.405,29.136],[-93.466,30.77],[-94.692,38.939],[-97.279,48.946],[-122.67,48.946],[-124.508,48.197]]]}\", \"title\": \"S&T Project 22060 Final Report: Modular Anode Sled Development and Testing for Cathodic Protection of Immersed Steel Structures\"}","source_transform":null,"status":"error"}
