Doosan Wins World’s Largest Seawater Desalination Project, worth US$ 1.46 billion, in Saudi Arabia

    - Project entails potable water output of 228 MIGD, sufficient to meet daily needs of 3.5 million people in capital, Riyadh
    - Company to construct hybrid plant combining MSF (Multi-Stage Flashing) and Reverse Osmosis (RO) technologies


Doosan Heavy Industries & Construction (Geewon Park, President & CEO) announced that it has received a Letter of Award (LOA) from the Saline Water Conversion Corporation (SWCC) for a seawater desalination project to be executed in Ras Az Zawr.


The project is worth US$ 1.46 billion, making it the largest desalination project in size in the world. With a capacity of 228 MIGD*, the plant’s daily potable water output will be the largest in the world, sufficient to meet the needs of 3.5 million people per day. To date, the world’s largest desalination plant is the Shuaibah Phase 3 seawater desalination project, with an output of 194 MIGD, which Doosan won in Saudi Arabia for US$ 850 million in 2005.


*MIGD (Million Imperial Gallons per Day): One MIGD amounts to 4,546 tons per day, sufficient to meet the requirements of 15,000 people per day.


The Ras Az Zawr seawater desalination project will be constructed in the Ras Az Zawr region, 75 km northwest of Jubail, an industrial city in eastern Saudi Arabia. The plant will supply water to the Saudi capital Riyadh.


Doosan will carry out the project on an EPC-basis, which will include engineering, production and installation of equipment and facilities, as well as testing and commissioning. The company is slated to complete the project by January of 2014. Notably, the plant will be constructed by adopting a hybrid method that will combine MSF (Multi-Stage Flashing) (160 MIGD) and Reverse Osmosis (RO) technologies (67.5 MIGD).


From winning Saudi Arabia’s first privately financed seawater desalination project, Shuaibah Phase 3, to winning the world’s largest desalination project, Ras Az Zawr, Doosan has put itself ahead of its Italian and French rivals in the upcoming bids for large-scale desalination projects in Saudi Arabia and in the neighboring Middle Eastern countries, such as Kuwait and the United Arab Emirates.


Senior Vice President Seokwon Yun (Head of the Water BG) at Doosan said, “Doosan was able to win the project because the client recognized Doosan’s technological prowess and project management capabilities.”


Since the 1990s, Doosan has been awarded desalination plant projects in the Middle East worth US$ 5.6 billion in total, with a cumulative daily output of 4.3 million tons. By winning the latest project, the company has further strengthened its market dominance in the region.
