(June 19, 2013) Officials from China’s Three Gorges Corporation and Project Construction Committee (TGPCC) paid a visit earlier this month to the troubled U.S. Chickamauga Lock in Tennessee as part of an information sharing exchange organized by the U.S. Army Corps of Engineers (USACE) — responsible for the operation and maintenance of navigation locks on the Tennessee River. TGPCC, established by China’s State Council to oversee construction of the massive Three Gorges Dam project, has concerns regarding its own ship locks: some 733 cracks were reported to have appeared in the east and westbound channels of the Three Gorges dam’s five-step shiplock, along with a worrisome distortion that may have been caused by crustal plate movement, among other issues. The dam’s ambitious and intensely complex ship lift, slated for completion in 2015, has yet to be tested.
