Abu Dhabi Gas Industries (Gasco) has prequalified twelve international engineering and construction firms to bid for an estimated $260m deal to build carbon dioxide recovery and injection facilities at the Habshan field in the southwest of the emirate.

The firms will submit technical proposals on 1 March and commercials bids by 12 April, according to sources close to the deal. A number of bidding firms have asked for a two week extension to prepare bids, but this has not yet been confirmed by Gasco.

Prequalified firms include:

• Hyundai Engineering & Construction
• Tecnimont
• Samsung Engineering 
• SK Engineering & Construction (SKEC)
• Technip
• Saipem SpA
• Dodsal
• Larsen & Toubro Limited
• Punj Lloyd Limited 
• Consolidated Contractors Company
• National Petroleum Construction Company (NPCC)
• CTCI Corporation

Gasco is expected to launch another five projects this year including a scheme worth about $160m, which will see nitrogen gas from Elixier, a joint venture of Abu Dhabi National Oil Company and Germany’s Linde Group, injected into Gasco’s gas fields. Front-end engineering and design (feed) work on these projects has been completed (MEED 14:1:11).

A related project, the Nitrogen Breakthrough, Nitrogen Recovery (NBNR) scheme, will prevent the injected nitrogen from seeping back to the surface, and is expected to be tendered in mid-2011.
