Abu Dhabi Company for Onshore Petroleum Operations (Adco) has extended the deadline for companies to submit prices on its estimated $2bn Bab Integrated Facilities Expansion project.

Companies have been asked to submit commercial engineering, procurement and construction (EPC) bids on 30 May, pushed back from a previous deadline of 9 May.

Adco retendered the Bab Integrated Facilities Expansion scheme on 22 December, a year after cancelling a previous tender on the project. The new tender is thought to have a reduced scope of works and the estimated budget has been reduced from $3bn to about $2bn, sources told MEED.

Technical EPC bids were submitted on 14 March. Companies and consortiums submitting technical bids are thought to include:

• China Petroleum Engineering & Construction Company (CPECC; China)
• JGC (Japan) / National Petroleum Construction Company (NPCC; UAE)
• Petrofac (UK)
• Saipem (Italy)
• SK Engineering & Construction (South Korea) / Intecsa (Spain)
• Tecnicas Reunidas (Spain)

The scope of work involves installing new facilities at Adco’s Bab field, located 160 kilometres southwest of Abu Dhabi city. As part of the original scope, surface facilities would be delivered for the Thamama-A, Thamama-H and Thamama-B production zones to achieve a total sustainable oil production rate of 450,000 barrels a day (b/d).

Adco is a joint venture of Abu Dhabi National Oil Company (Adnoc) and six international oil companies. Adnoc recently completed the joint venture by awarding stakes to two Chinese companies.
