US-based engineering group CH2M Hill has won a contract to carry out the project management consultancy (PMC) on a major gas processing project in Abu Dhabi.

CH2M Hill will oversee the engineering, procurement and construction (EPC) stage on phase two of the Bab compression facilities expansion project, owned by Abu Dhabi Company for Onshore Operations (Adco).

The estimated $500m project includes a new compressor station and new gas-gathering system at the Bab field, 150 kilometres southwest of Abu Dhabi city. The work is part of the second-phase expansion of the Bab field, which will increase its capacity to 2.5 billion cubic feet a day (cf/d) from 1.8 billion cf/d.

The project is still in the bidding phase, with EPC contractors submitting commercial bids in December. The contract is likely to be awarded in the first quarter of 2013.

Spain’s Intecsa, UK-based Petrofac and South Korean groups Samsung Engineering and SK E&C all submitted commercial EPC bids. The latter company also carried out the project’s front-end engineering and design (feed) phase.

Adco is a joint venture of state-owned Abu Dhabi National Oil Company (Adnoc), the UK’s BP, the US’ ExxonMobil, the UK/Dutch Shell Group, France’s Total and Portugal’s Partex Oil & Gas.
