The capacity exceeded the initial expectation of 103 per cent for the whole year.

Cao Tuan Si, deputy director of Dung Quat Oil Refinery said that the company has plans to increase the capacity to 110 per cent, which will contribute to stabling the petroleum and oil market.

The company also accelerates the sales and delivery for the petroleum and gasoline distributors and simultaneously is proactive in building long-term plans for crude oil purchase to ensure a stable operation with high capacity.

Dung Quat Oil Refinery plays a crucial role in ensuring national energy security by providing 35 per cent of petroleum and petrol for the domestic market.

Although Dung Quat Oil Refinery is operating at a higher capacity compared to the designed one, its operator BSR is under inspection to clarify the reason causing the existing price fluctuations of petroleum and oil in the market recently.

Along with BSR, other 15 key petroleum and petrol trading facilities, such as Nghi Son Refinery and Petrochemicals LLC, are also under inspection.

The inspections will last for up to 60 days and will cover the operation of these facilities and refineries from January 2017 to the end of June this year.
