- The Cannelton Hydroelectric Plant near Hawesville, Kentucky is the construction of a 88-megawatt (MW) run-of-the-river hydroelectric plant, which is the first of five such plants under development at existing dams on the Ohio River for American Municipal Power. Kiewit Corp., Omaha, was awarded the contract for cofferdam and excavation at Cannelton, DC+ was called on to assist Kiewit in the development of an automated Cuttoff Slurry Wall Plant. This plant was to be built on-site because of the need for 515,000 SF of Cement-Bentonite Cut-off Wall for the coffer dam construction. The system consisted of an Allen Bradley controlled batch plant that utilized Wonderware Archestra HMI technology for operator control. The programming and operator interface was built with many considerations in mind.
Past experience and testing proved that the way the slurry was mixed and the equipment utilized influenced the final results of the slurry; consequently the mixing plant, was also designed to optimize performance. Also with the strigent formula requirements and unknown final formula recipe to be developed on-site, we developed a recipe page for the engineering group to tune the process after lab results from the previous batches were evaluated.
