OHIO RIVER COAL TRANSSHIPMENT DESIGN STUDY
Krech Ojard developed alternative conveyor/barge/marine conceptual configurations for the transshipment of 30 M Tons annual with peak volume of 5500 TPH load rate at the barges for this Ohio River coal transshipment facility. Fuel source was delivered to site by unit train and transferred via overland conveyor to shoreside surge bin/feed conveyors. Feed conveyors traveled over water to terminal surge bins and a traveling tripper double sided loading terminal. KOA prepared general arrangement, flow diagrams, mechanical arrangement, and cost estimates for the alternatives.
Priorities included continuous operation of feed belt, optimal 1 x 5 barge fleeting/loading operations, minimization of required surge, and continued operation at 110 yr flood elevation with 6 fps current. All mechanical and operational infrastructure placed above 500 year flood elevation.
Elements of the alternatives included elevated traveling tripper, stationary working deck barges between cells, height adjustable discharge chute, trim chutes, barge rake-to-rake discharge interruption/surge demand, space requirements for future dust collection, reversing cross conveyor, contingency barge loading configuration, control systems, and maintenance infrastructure for periodic replacement of drives and head pulleys.
Overwater conveyors included integral washdown pan and piping as well as full length hoop covers for dust control. Outlined systems for fire protection and dust collection. Reviewed electrical service demand for primary devices as well as control, fire protection, dust collection, and lighting systems.
