CHINA'S Zhenhai Refining and Chemical Co has completed expansion of its berth facility at Suanshan Port in Beilun harbour in Ningbo. The company said the 250,000 deadweight tonnage (dwt) berth, which began operations earlier last week, is the largest crude oil berth in China. Operation of the berth is expected to reduce Zhenhai Refining's crude oil transportation costs. 'With the expanded berth in operation, it is estimated that the company can save up to 30 US cents per barrel of Middle East crude oil by transporting it in 200,000 dwt oil vessels,' said chairman Zhang Jiaren. Zhenhai Refining is a H-share counter listed on the Hong Kong stock exchange. At Beilun, Zhenhai Refining owns and operates five crude and product berths. The expansion work was conducted at the port's largest berth to enable it to receive oil vessels of up to 250,000 dwt. After the expansion, Suanshan port facility's annual capacity has increased from 15 million tonnes to more than 20 million tonnes. Zhenhai Refining has an annual primary refining capacity of seven million tonnes of crude oil, making it the eighth largest refiner in China.
