Abu Dhabi Marine Operating Company (Adma-Opco) has received bids for the second of four major offshore packages tendered at the start of 2012.

Adma-Opco has delayed the bid deadlines several times for engineering, procurement and construction (EPC) contracts on its Umm al-Lulu and Satah al-Rasboot (Sarb) field developments, but all technical proposals are now expected to be in by the end of June.

Technical EPC bids were submitted on 12 June for the third package of the Sarb full field development, which includes the construction of offshore pipelines and platforms.

At the same time, Adma-Opco has asked for bids on the fourth Sarb package, covering the main processing plant, by 19 June, having pushed the deadline back from 22 May.

The Sarb full field development project is being tendered in five packages estimated to be worth a combined value of more than $1.5bn.

The first EPC contract, to build two artificial islands 120 kilometres of the coast of Abu Dhabi city, was awarded to Belgium’s Dredging International and Qatar-based Middle East Dredging Company (Medco) in 2011.

For the Umm al-Lulu full field development project, technical EPC bids were submitted for the first package on 5 June.

Contractors bidding for the estimated $500m contract include South Korean groups Hyundai Heavy Industries and Samsung Engineering, US-based McDermott and Abu Dhabi’s National Petroleum Construction Company (NPCC).

The technical bid deadline for the second package of Umm al-Lulu, estimated to be worth $650m, has been delayed until 19 June from a previous cut-off date of 22 May.

Deadlines for commercial bids on all four Sarb and Umm al-Lulu packages have been delayed until after Ramadan, which ends on 18 August.

The projects are part of Adma-Opco’s plan to add 300,000 barrels a day (b/d) of additional production from four new offshore fields, with about 100,000 b/d coming from both Umm al-Lulu and Sarb.

The contract for full production facilities at the Nasr field is expected to be tendered in the third quarter of 2012, with the front-end engineering design currently being carried out by the US’ Fluor.

Adma-Opco is majority-owned by the state-run Abu Dhabi National Oil Company (Adnoc), with minority stakes held by UK-based BP, France’s Total and Japan Oil Development Company (Jodco).
