Vietnam's sole refinery was closed for two months in mid-July for maintenance and fixing 75 technical faults.

The Binh Son Oil Refining and Petrochemical Co Ltd, the operator, said it had cost $40.5 million though a group of contractors led by France's Technip had been signed up for around $25 million.

Nguyen Hoai Giang, Binh Son's CEO, said some of the equipment had deteriorated and had to be replaced.

The refinery resumed operation at full capacity on September 13, two days earlier than expected.

The next maintenance is planned to be done in four years' time, but by a team of Vietnamese experts and engineers.

Before it closed Dung Quat Oil processed and sold more than 3.3 million tonnes of gasoline.

It targets a total of 5.6 million tonnes this year.
