The Huangzeshan-Yushan crude oil pipeline in Zhoushan, East China's Zhejiang province was put into operation on Dec 28. 

The 46.5-kilometre pipeline, which cost 1.6 billion yuan ($230.11 million) to build, has a designed transmission capacity of 20 million metric tons per year. 

The pipeline, 45.7 km of which is laid under the sea, is the first of its kind in the province. 

An important supporting facility for the Zhoushan green petrochemical base, the pipeline will play a critical role in improving resource allocation for the city's crude oil industrial chain and guaranteeing the energy supply of the base, said local authorities. 

The pipeline will also greatly reduce crude oil transmission time, cost and losses, said a representative of Zhejiang Petroleum Storage and Transportation Co Ltd, the company in charge of the pipeline operations.
