Abu Dhabi National Oil Company (Adnoc) has extended the deadline to 26 August for companies to bid for the contract to reclaim a series of offshore islands for the development of its Hail and Ghasha sour gas fields.

The initial bids submission date was 12 July.

The companies that have prequalified to bid for the contract that involves dredging and rockwork are:

• Archirodon (Greece)
