The 446-metre wharf, which includes a 150-metre trestle bridge, could dock the largest LNG carrier in the world, the company newspaper said.
The Dalian LNG project, comprising a wharf, receiving terminal and gas pipelines, is scheduled to be operational in April 2011.
PetroChina is expected to sell its 75 percent stake in the project to Kunlun Energy (0135.HK), a company controlled by PetroChina, and is diversifying its business into LNG supply, vehicle fuel gas and city gas from oil exploration.
