Abu Dhabi Marine Operating Company (Adma-Opco) has issued tenders worth a combined $4.5bn for the development of at the offshore Umm al-Lulu and Satah al-Rasboot (Sarb) fields.

Technical proposals for the facilities are due to be submitted in April and commercial offers are expected a month later.

However, prequalified firms have complained that they have been unable to open the tender documents received from Adma-Opco, meaning they are still unaware of the exact scope of work.

The development of the fields is understood to include several engineering, procurement and construction (EPC) packages, including building wellhead towers and pipelines, gas processing facilities, utilities and accommodation (MEED 2:12:11).

Adma-Opco is developing the Umm al-Lulu, Nasr and Sarb oil fields as part of the Abu Dhabi’s plan to boost offshore production capacity to 1.75 million barrels a day (b/d) by 2020, from 1.1 million b/d currently. The Umm al-Lulu and Sarb fields will add 100,000 b/d each.  

The US’ Fluor was selected in October for the front-end engineering and design (feed) for the development of the Nasr field, increasing production to 65,000 b/d over two phases. Tenders are not expected until 2013.

Adma-Opco is a joint venture of Adnoc, the UK’s BP, France’s Total, Japan’s Inpex and Japan Oil Development Company.
