The Dalian Port of northeast China's Liaoning Province provided transit shipment service for 8.59 million tons of crude oil last year, topping that in north China ports, said local source.

Dalian Port built a 300,000-ton dock specialized in oil shipment in June 2004, which made it the biggest oil transit port in northern China.

The dock was constructed after the repeated discussion of experts from Dalian University of Science and Technology and Liaoning Maritime Administration.

In addition to the existing 150,000-ton dock, the Dalian Port saw an increasing handling capacity this year. The port mainly provides oil transit shipment services to the petrochemical companies in the pan-Bohai Sea region.
