Several workers have been injured in a fire at Kuwait’s Mina al-Ahmadi refinery, one of two refineries marked for expansion as part of the country’s $14bn Clean Fuels Project.

The fire broke out at a waste treatment facility and did not interrupt production according to Kuwait News Agency (KUNA), which functions as a branch of the Information Ministry.

Several workers suffered injuries and were transported to hospital for treatment, the news service said.

Kuwait National Petroleum Company’s (KNPC) deputy chief for support services told KUNA an investigation would be launched to the reasons behind the fire.

In April 2014 engineering, procurement and construction (EPC) contracts were issued for $12bn-worth of contracts on the Clean Fuels Project to expand and upgrade the Mina al-Ahmadi and Mina Abdullah refineries.

Workers are expected to be mobilised on the project in October this year.
