Zhoushan in East China's Zhejiang province supplied 6.02 million metric tons of bonded fuel oil in 2022, up 9.1 percent year-on-year, according to official statistics. 

One of the key reasons behind the increase was the efforts that local authorities made to improve a group of supporting facilities, including adding more barges, building new anchorages, and increasing warehouses. 

The number of barges increased to 85, of which 53 completed the upgrading of their surveillance video systems. 

The launch of a 410,000-square-meter warehouse and the Huangzeshan-Yushan crude oil pipeline has also played a significant role in bolstering the development of Zhoushan's bonded fuel oil industry, said a local official. 

Zhoushan authorities also strengthened cooperation with industry-leading enterprises like China Merchants Energy Shipping Co Ltd and COSCO Shipping, attracting business to the city and helping newly established bonded oil enterprises accelerate their business operations. 

The supply of bonded fuel oil across customs areas in 2022 reached 3.26 million tons, a year-on-year increase of 18.42 percent, accounting for more than half of the city's total. 

In addition, the production and processing capacity of Zhoushan's bonded oil enterprises expanded greatly in 2022, with the production capacity of its low sulfur reaching two million tons a year.
