The project supported replacing critical cooling water intake lines in the Mississippi  River without shutting down operations. Cajun designed a custom helical piling​ system capable of installation under existing overhead lines with as little as 5 feet of​ clearance, carrying over 75 tons of vertical capacity. This system supported an​ overhead gantry crane used to replace intake lines section by section, ensuring​ continuous cooling water supply despite river level challenges and COVID-19​ disruptions.
