Corps Assets Arrive At Demopolis, Repair Plan Takes Shape

摘要

Almost a month has passed since a large portion of the upper miter sill at Demopolis Lock broke off and fell into the chamber on January 16, and the plan for returning the lock to normal operations is taking shape. The Mobile Engineer District's maintenance fleet, including the mvs. Tenn-Tom, Lawson and Constitution and their associated crane and deck barges, arrived to the lock from downriver on February 2. Corps leaders are keeping the Tennessee-Tombigbee Waterway Project's old crane barge, the R. Davis, equipped with a Manitowac friction crane, below the lock. The Black Warrior-Tombigbee Project's mv. Law-son and its floating plant, the Choc-tawhatchee, and the Tenn-Tom Project's mv. Tenn-Tom and new crane barge, equipped with a Liebherr crawler crane, locked through February 5. Floating plant crew members then restacked the lock's upper stoplogs to elevation 84 feet, which gives lock operators more control over chamber water levels in the face of upper pool fluctuations.
