The deadline for commercial bids on the second-phase development of Abu Dhabi’s offshore Nasr field has been pushed back by two weeks, according to sources close to the bidding process.

Project owner Abu Dhabi Marine Operating Company (Adma-Opco) received technical engineering, procurement and construction (EPC) bids for the project’s two main packages in the first quarter of the year.

Adma-Opco is carrying out a full-field development of the Nasr field, which is located 30 kilometres to the northeast of the firm’s active Umm Shaif field in the Gulf.

The bid deadline for EPC package one, which covers the construction of seven wellhead platforms, pipelines, modifications to the Integrated Gas Development (IGD) – Habshan platform (HAP) and associated facilities, has been extended to about 4 May from 20 April.

The larger second package, which covers the construction of three processing platforms and associated facilities, has been given a deadline of around 6 May, pushed back from 22 April.

Companies preparing to bid for the two packages were informed of the bid delays via a letter from Adma-Opco.

Adma-Opco is likely to award the EPC contracts in the third quarter of 2014 after an assessment of the commercial proposals.

The full-field development is the second phase of the expansions of the Nasr field. Phase one, covering the early production facilities, is currently under execution after the EPC deal was awarded to Indian contractor Larsen & Toubro in 2011.
