    Keeping the river open for business, dredging contract awarded

    The Memphis District U.S. Army Corps of Engineers is responsible for keeping the Mississippi River open for commercial navigation year-round. One way the district does this is through contract dredging, which keeps the river channel at a depth that allows the river barge industry to dependably transport goods up and down the river. Ensuring the district delivers on this charge, the Memphis District recently awarded a contract in the amount of $7,335,450 to Great Lakes Dredge and Dock, LLC for the rental of a 24-inch hydraulic cutterhead dredge, discharge pipe, and attendant plant. The contract was awarded June 2, 2022, with an anticipated completion date of Feb. 28, 2023.

With the Mat Sinking Unit stocked with ACM and ready to go, the district can continue to provide riverbank protection along with sound, navigable waters for the industries transporting goods up and down the river.

    ACM casting project complete, revetment prepared for season ahead

    “The project is designed to supply the current Mat Sinking Unit with Articulated Concrete Mattress (ACM) to use for revetment to maintain a safe and reliable navigation channel for commercial towboats in the Mississippi River,” Project Manager Zach Cook said. “If the project were not completed, there could be failures or cutoffs on the Mississippi River banks.” Cook is describing the recently completed project named “Richardson Landing Articulated Concrete Mattress Casting – Mississippi River Channel Improvement Project” located at Richardson Landing, near Drummonds, Tennessee, Mississippi River Mile 769.

The bridge is a vital piece of the Memphis District infrastructure. It is one of only two access points to the fleet of dredges and material barges that transport over 175 million tons of cargo along the Mississippi River. The Memphis District is directly responsible for servicing 355 miles of the Mississippi River watershed, and failure to maintain these operations could cost the nation over a billion dollars in fuel and shipping costs.

    Army Dive Team restores vital district asset

    “The highest risk and resource-intensive Mission Essential Task (MET) we collectively train on is port opening and harbor clearance,” 511th Engineer Dive Detachment Commander Cpt. Olivia Schretzman said. “If we do not provide accurate infrastructure assessments, open ports, repair bridge sections, or clear obstacles in inland waterways, we negatively impact all sustainment and maneuver operations. It is a no-fail mission.” Schretzman commands the 511th Engineer Dive Detachment, a 25-Soldier team that deploys worldwide, performing complex and dangerous engineer tasks at depths of up to 190 feet. Schretzman explained that simulating a damaged bridge is a difficult task, so when the Memphis District reached out for assistance, both parties would benefit from the job. “The Ensley Engineer Yard had a partially sunken bridge that needed repairs, and we needed high-intensity port opening training,” Schretzman said. “This operation became known as Operation Mississippi Freedom.”

    Completed Below Island 9 Project to benefit navigation industry, public

    Congratulations to the Memphis District Below Island 9 Project Delivery Team for achieving total project completion on May 6, 2022. The project area, located in Lake County, Tennessee, was identified as a low water problem spot by local partners in the navigation industry. This area has been dredged by the Memphis District’s Dredge Hurley in 2020 and 2021, yet the problem spot persisted. To come up with a long term solve, a project delivery team came together to complete a dike construction project.

    Dredge Hurley returns after completing impressive season

    The Memphis District’s Dredge Hurley was welcomed home after returning to its home port, Ensley Engineer Yard in Memphis Harbor, Sunday morning, Nov. 21. Their homecoming signifies the end of yet another highly productive dredging season. The Hurley started this season May 3. And in just over six months’ time, the crew dredged several hundred miles of the Lower Mississippi River.
