China plans to start trial navigation at the world's biggest hydroelectric power project's ship lock tomorrow after two preliminary trails ended successfully, the state media reported on Sunday.
Two preliminary tests have been done as the water storage in the reservoir completed on June 10,
five days ahead of the schedule. A single ship succeeded in passing through the reservoir on June 13.
On June 14, another test navigation of a shipping team on Yangtze river was also successful, Xinhua news agency reported from the dam site in Yichang, in China's Hubei province.
"The two pre-tests were both satisfying, especially in the interaction between the ship, the water and the lock, the director of the Yangtze river Three Gorges Navigational Bureau, Zhang Qingsong said.
The inspection on the ship lock would continue even after the trial navigation, Zhang said, adding the second phase of trial navigation will be done when water flow of the Yangtze river would reach 40,000 cubic meters per second this July.
Three major media in China, Xinhua news agency, China Central Television and China National Radio are all ready for the live broadcast of the trial navigation tomorrow morning, the report said.
The ship lock is expected to open to all ships on June 20, earlier than scheduled, as many ships are stuck near the three Gorges dam due to water storage.
The ban on night navigation in the reservoir from the three gorges dam to Wanzhou in the upper reaches of the Yangtze river was lifted on June 13 after a lapse of 30 days. However, night navigation is still forbidden to those ships that pass the lock for the first time.
