Harbor Dredging Surveys for the Ohio Power Company

Ohio River near Metropolis, Illinois

Eisenbraun and Associates was awarded a contract for the task of performing three hydrographic surveys at the Cook Coal Terminal Harbor on the Ohio River near Metropolis, Illinois. The purpose of the survey was for the planning, design and verification of a dredging project for this terminal facility of the American Electric Power Company. A condition survey was completed to determine areas and quantities to be dredged. A pre-dredge survey was then performed prior to commencement of the dredging operations. A post dredge survey was subsequently performed to determine the actual pay quantities for post dredging conditions. The firm recovered control previously established by American Electric Power at the site and utilized its GPS positioning system to capture the horizontal position of the survey vessel during the survey. E/A’s 26-foot enclosed hydrographic survey vessel was utilized for this project. It was necessary to coordinate the survey work with the movement of the barges in the harbor. The Cook Coal Terminal is a major coal transloading facility that currently loads in excess of eleven million tons of rail to river coal per year with 24-hour coal loading operations. A total of 71 cross-sections were surveyed during each phase of the project with data captured on a 25-foot interval. In addition, a bathymetric map was created for each phase, and cross section plots were developed in CADD with quantities computed by applying a dredging design template provided by the client. Finally, echosonic sounding charts were recorded for all ranges. E/A efficiently completed the project within the project schedule, and provided the vital data needed by the American Electric Power Company to successfully complete the dredging project.
