Jan 08, 2023 (China Knowledge) - A major crude oil pipeline connecting a storage farm in Zhoushan of Zhejiang province to a mega refiner known as Zhejiang Petroleum & Chemical (ZPC) has started pumping oil for the first time.

This 46.5-kilometer (28.89 miles) pipeline is designed to carry 20 mln tons of crude oil a year, is expandable to 30 mln tons. The pipeline cost RMB 1.6 bln (USD 229.44 mln) to build, with investment from Zhejiang Petroleum Co Ltd, a unit under state-run Zhejiang Energy Group, and two other local firms.

The pipeline has a diameter of 0.8 meter, spanning 800 meters over land and 45.7 kilometers under the sea. It starts from the Huangze Mountain’s crude oil storage and stretches to ZPC refinery, which is China's single-largest refiner with daily processing capacity of 800,000 barrels.

It is the first time that China adopted the sea-to-sea directional drilling crossing technology, setting new records for the world's longest crude oil pipeline, the largest pipe diameter, and the deepest water level applying such technology.

The pipeline has the advantages of lower transportation cost, safer, more stable and environment-friendly logistic, according to official said in a statement. In conjunction around the construction of the entire oil industry chain in the China (Zhejiang) Pilot Free Trade Zone, Zhejiang Petroleum has deployed more than 200 comprehensive energy supply stations across the province.
