Libya’s Mellitah Oil & Gas Company (MOG) has launched its second project in a week, inviting firms to prequalify for the engineering, procurement and construction (EPC) of a new water treatment facility at the Abu Attifel field.

Interested firms have been asked to submit their prequalification documents by 14 February for the deal for a building to house a treatment plant at the field’s natural gas liquids (NGL) plant.

The 90 cubic metres-a-hour (cm/h) reverse-osmosis water treatment plant will include pretreatment and softener units for brackish water.

The project will be tendered on a turnkey basis, and covers civil, electrical and mechanical engineering, training, spare parts for operation and maintenance and commissioning.

Companies, which have previously participated in MOG tenders in 2010, need only send a headed letter to the contracts department manager expressing interest in the deal by the deadline.

The Abu Attifel field is located in the Area-B onshore concession approximately 300 kilometres south of Benghazi. Production averaged more than 80,000 barrels a day in 2010, before being shut down by Libya’s civil war. It restarted operations in September 2011.

MOG has also invited firms to prequalify by 28 February for the supply of a subsea production system at the offshore Bahr Essalam oil field in the NC-41 concession, 100-metres off the Libyan coast in the Mediterranean.

The concession is operated by MOG, a joint venture of Italy’s Eni and state-owned National Oil Corporation.
