The US’ Stone & Webster has won two deals to oversee the design of new offshore oil production facilities in Abu Dhabi, sources close to the projects tell MEED.

Stone & Webster submitted bids for the two project management consultancy (PMC) contracts during a 21 March bid round, and is now the preferred bidder for the project client, Abu Dhabi Marine operating Company (Adma-Opco). A formal deal is set to be completed by mid-May (MEED 22:3:10).

The company will oversee front end engineering design (Feed) studies for the development of the Sath al-Raazboot (Sarb) and Umm al-Lulu fields.

MEED reported in February that the US’ Fluor Corporation had won the main Feed contracts on the two schemes (MEED 2:4:10).

Adma-Opco released a statement confirming the US firm as the main design contractor on 2 May.

The first deal covers the design of offshore facilities to pump 100,000 barrels a day (b/d) of oil from the previously untapped Sath al-Raazboot field. Fluor won the Feed contract on this deal in January.

The second deal covers the design of a second phase of production facilities at the Umm al-Lulu field, which will increase production from 35,000 b/d to 100,000 b/d. Sources close to the project tell MEED that Fluor was awarded the deal in February after direct negotiations.

The projects are part of a wider programme being led by the two offshore operators in the emirate, Adma-Opco and Zakum Development Company, to boost Abu Dhabi’s offshore production capacity from 1.1 million b/d currently to 1.75 million b/d by 2020.
