Nine companies and groups have been prequalified, but not all are expected to bid. The EPC contract is estimated to be worth $350 million-450 million and will cover a 25 million-50 million-gallon-a-day (g/d) plant. Bidders are expected to submit a main offer, which will include the supply and installation of two 12.5 million-g/d units, and an alternative offer for two additional units of a similar capacity. The units will use multi-stage flash (MSF) technology.
The scope of work will also include the construction of a seawater-cooling system. The facilities are expected to be commissioned in just under 30 months. At a later stage, the MEW plans to double the capacity of the desalination plant.
Power and steam for the proposed desalination project will be supplied from the 2,400-MW Subiya power plant.
