Sooner Generating Station

Conveyors 10 & 11 Replacement Project

 

Wolf Point Engineers & Contractors, a Division of NAFCO, in 2020 completed substantial completion of the Conveyors 10 & 11 Replacement Project at the Oklahoma Gas and Electric Company Sooner Generating Station near Red Rock, Oklahoma.

 

The contract was awarded to Wolf Point/NAFCO in February 2019. The project consisted of replacing the aging walk-through galleries, support structures and over-2,100-foot-long, 36-inch-wide 740 TPH plant-feed conveyors 10 and 11 with completely new conveyors, 12.5-foot-diameter tubular galleries, chutes and new foundations. Wolf Point’s scope of work included engineering, procurement, fabrication, demolition and installation.

​

The tubular galleries contain two 36-inch-wide conveyors with a maintenance walkway between them. Fabrication was done at NAFCO’s Cullman, Alabama, fabrication facility. The tubular galleries were fabricated and shipped in 40-foot sections. Shop assembly to the greatest extent possible included the installation of conveyor stringers, idlers and walkway, explosion venting, louvers, as well as some of the piping systems.

​

Wolf Point also provided deep foundations, chutework, electrical systems, dust control, gallery ventilation, wash-down and fire protection and explosion venting systems.

​

Sooner Station is an operating power plant. The project was scheduled around a planned outage beginning in February 2020. Demolition of the existing conveyors and installation of the new conveyors and tubular galleries occurred during the ten-week outage.

​

The conveyor system handles Powder River Basin (PRB) sub-bituminous coal.
