Tianjin Port unveiled on Oct 17 what it says is the world's first dock to operate with zero carbon emissions.

The dock, located in the C Area of Beijiang port's intelligent container dock zone, was put into service after an inauguration ceremony on Sunday.

The dock has three berths, each with a loading capacity of 200,000 tons, and a length of 1,100 meters. It can berth two vessels each with a weight of 200,000 tons simultaneously or two vessels, each with a weight of 100,000 tons and a third one with a weight of 70,000 tons.

Container handling capacity is estimated at 2.5 million twenty-foot equivalent units per year, according to Tianjin Radio.

Chu Bin, Party chief and president of Tianjin Port Group, said construction of the dock took only one year and nine months, reflecting "Chinese speed".

He added that the port group aims to become the world's top intelligent port.

During the first three quarters, the port handled 351 million tons of cargo, a historical high, and grew by 4.5 percent year-on-year.

During the period, it was No 8 on a list of the world's largest ports in terms of its total container handling capacity, the company said in a news release.
