Libya’s Azzawiya Refining Company (ARC) has invited firms to prequalify for a deal to provide refinery maintenance services at its facility, 45 kilometres west of Tripoli.

The company has set a deadline of 22 July for the submission of documents for the heater maintenance scheme, which will be executed in a four-week period during a planned maintenance turnaround scheduled to begin in the second half of 2013.

The work includes the replacement of radiant casing and convection roof plates, as well as replacing tubes, fittings, and lining. It will also include the replacement of a damaged flue gas collector and associated works, such as dismantling, cleaning, inspection, welding, refractory renewal, coil and tube installation and starting up the heaters.

ARC will provide all the materials for permanent installation required to complete the above works, such as steel plates, bricks and insulation material. However, consumable materials and equipment will be provided by the contractor.

ARC is a subsidiary of state-owned National Oil Corporation (NOC), operating one of the country’s main refineries. The 120,000 barrel-a-day (b/d) refinery was commissioned in 1974. NOC plans to upgrade the refinery adding a new residual catalytic cracker unit, methyl tertiary butyl ether (MTBE) facilities and a sulphur treatment plant.
