The flotilla of a super marine Tianbao 01 oil tanker sails through the dual-passage and five-step navigation lock of the Three Gorges Project in Yichang City, central China's Hubei Province, July 1, 2008. The 24.2-meter high Tianbao 01 oil tanker, a China-made new vessel for the order from Greece, is dragged by a tugboat (L) to waltz through the Three Gorges Dam and Gezhouba Dam under the multiple water levels control methods by the Three Gorges Navigational Bureau.
