GS Engineering & Construction wins $70m deal

Bahrain Petroleum Company (Bapco) has awarded South Korea’s GS Engineering & Construction a $70m deal to build a wastewater treatment plant at the Bahrain Refinery.

GS’ price of approximately $70m beat rival proposals from eight companies, including an $85m bid from CTCI Corporation of Taiwan and $87m from Samsung Engineering, also of Korea.

The plant will gather wastewater from Bapco’s 267,000 barrel a day Sitra refinery, 20 kilometres from the capital Manama, before treating it for reuse at the refinery. The project is expected to take 27 months to complete.

The plant will treat approximately 19,200 cubic metres of water a day, stripping out hydrogen sulphide and ammonia, which are typical components of sour water from refineries. In addition, the wastewater generated at the refinery is challenging to treat due to its high salinity, high temperature and the stringent specifications on treated water quality set by the government.

The plant will use a design based on the membrane bio-reactor process. The US’ CH2M Hill was awarded the front-end engineering and design (Feed) deal in August 2009.

Bahrain is planning a $2bn upgrade to the refinery, as well as a new pipeline, which will connect it to crude oil supplies from Saudi Arabia. Studies are currently underway by Bapco and US consultant, Chevron Lummus Global (MEED 13:8:10).
