on December 28, the Huangzeshan-Yushan crude oil pipeline project was successfully put into operation, with a total of about 60,000 cubic meters of crude oil transported, and the facilities and equipment operated stably
.

As a key project of Zhejiang Province's three-year action plan for green and low-carbon energy development and price stability, the project is the first 20 million ton crude oil pipeline put into use in Zhejiang Province during the 14th Five-Year Plan period, which started construction in October 2021 and was completed
after more than a year of efforts.
During the construction process, the project adopted the directional drilling technology for the first time, breaking the three records of sea-to-sea directional drilling of the world's crude oil pipeline with the longest pipeline, the largest pipe diameter and the deepest water level, breaking through the difficulty of the "stuck neck" of
the project.
The oil trial operation marks the interconnection between Huangzeshan Oil Storage and Transportation Base and Zhoushan Green Petrochemical Base, which is of great significance
to improve the resource allocation capacity of crude oil industry chain in China (Zhejiang) Pilot Free Trade Zone and meet the energy security of Zhoushan Green Petrochemical Base.

Huangzeshan-Yushan crude oil pipeline project starts from Huangzeshan Oil Storage and Transportation Trade Base in Daishan County, Zhoushan City, crosses the Daiqu Ocean to Zhoushan Green Petrochemical Base on Yushan Island, with a total investment of 1.
6 billion yuan and a total length of about 46.
5 kilometers, of which about 45.
7 kilometers of submarine pipelines and 0.
8 kilometers of onshore pipelines, with a design pressure of 6.
5 MPa, a pipe diameter of 813 mm, and a designed annual transportation capacity of about 20 million square meters
