At least four international engineering firms have submitted final proposals for two contracts to oversee the design of offshore oil and gas facilities for Abu Dhabi Marine Operations Company (Adma-Opco).

The UK’s Amec, Australia’s WorleyParsons and two US companies, Stone & Webster and Mustang Engineering, are among the bidders for the project management consultancy (PMC) contracts. They submitted their proposals to Adma-Opco on 21 March.

The winning bidders will oversee work done by the US’ Fluor, which is the main front end engineering and design (Feed) contractor on both projects.

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.
