The damage caused by a fire at the Ruwais oil refinery in Abu Dhabi in January is still being investigated by an insurance company, according to oil industry sources.

Abu Dhabi National Oil Company (Adnoc) said on 11 January that a fire had been contained at the site of its largest refinery operated by subsidiary Abu Dhabi Oil Refining Company (Takreer).

After the insurance investigation Takreer is likely to award a contract to restore the damaged facilities, which is estimated to be worth up to $1bn.

The fire has damaged the residual fluid catalytic cracking (RFCC) unit, built as part of an expansion project to double the capacity of the refinery completed in 2015.

The unit was built by South Korea’s GS Engineering & Construction, which was awarded an engineering, procurement and construction (EPC) contract for the work estimated at about $3bn. Industry sources told MEED that GS E&C is likely to be awarded the contract to restore the facilities.

Ruwais is the largest refinery in the UAE, with a capacity of about 800,000 barrels a day (b/d).

In February, Adnoc put out a tender to buy more than 240,000 tonnes of gasoline for March and April due to a supply shortfall caused by the fire damage. This was reportedly followed by a tender to buy 316,000 tonnes of gasoline over May and June.
