| 8 | Desalination & Water Reuse | February-March 2016 BUSINESS Doosan Babcock wins maintenance and support deal at giant Taweelah plant Energy engineering company, Doosan Babcock, has won a contract with Taweelah Asia Power Company (Tapco) to provide essential maintenance and technical support services for Tapco's desalination plant in Abu Dhabi. The eight-year maintenance agreement contract includes technical support, parts and equipment provision and repair and maintenance services at Abu Dhabi's Taweelah B power and water desalination plant, the second largest facility of its kind in the United Arab Emirates (UAE) according to Doosan Babcock. It claimed to have beaten off "stiff competition" to secure the contract, Boart Longyear wins slant well deal California American Water (CalAm) has selected drilling firm, Boart Longyear, to construct seven to nine source water slant wells. They would draw ocean water for a desalination facility proposed as part of CalAm's US$ 320 million Monterey Peninsula Water Supply Project to replace the local reliance on the Carmel River as its primary source of water supply and is expected to be complete in 2019. Boart Longyear provided the lowest cost of the three respondents to a request for proposals issued in September according to CalAm. Boart Longyear's proposal was about US$ 2.8 million a well, which was slightly lower than CalAm's estimate. Respondents were evaluated on business, technical and price criteria. "The knowledge we have gained from the test well helped us to create a meaningful request for proposals that has resulted in quality proposals with well-informed cost estimates and an advanced understanding of the task at hand," said Cal Am's vice president of engineering, Deana Donohue. "This is a fantastic opportunity for Boart Longyear to extend our footprint in the desalination market and be a leader in this industry," said Boart Longyear's territory contracts manager, Jason Lamb. CalAm and Boart Longyear constructed a test slant well earlier this year to assess the feasibility of the technology at CalAm's preferred project site. Water quality results and production capability of the test slant well have so far exceeded expectations said CalAm. CalAm has passed the responses to the request for proposals and its evaluation report and draft contract to the Monterey Peninsula Water Supply Project Governance Committee, which will make further recommendations. The proposals and evaluation report will be posted to the project's website, where more information on the Monterey Peninsula Water Supply Project can be found, including data from the test slant well and the latest news and updates on the project's progress. Oman seeks bids for desalination inlets consultation Oman Power and Water Procurement (OPWP) company has invited bids from consultancies to investigate the best sea- water intake and outfall location for two independent desalination projects. The private developers that win the concession from the state-owned OPWP throughout its "unique one-stop shop solution that combines original equipment manufacture (OEM) engineering, integrity management and mechanical maintenance expertise. Under the agreement Doosan Babcock will ensure the optimum performance of six thermal boiler units, five heat recovery steam generators, 13 multi-stage flash water desalination units and 12 potable water tanks. Doosan Babcock's vice president, global service, Steve Hunt, said the contract represented a significant strategic step for Doosan Babcock's growing business in the UAE. He added: "Combining our integrity management, maintenance and OEM capabilities, we are ideally placed to help Taweelah B continue to provide a secure source of water and power for the residents of Abu Dhabi. "The scope of works will be led by Doosan Babcock, while the technical expertise will be provided by other members of the Korean parent company, including Doosan Heavy Industries' Water Business group and Doosan Engineering and Construction." The contract follows Doosan Babcock's recent opening of its specialist Middle East and North Africa technical hub in Abu Dhabi. will build the projects at Salalah and Sharqiya. The Salalah project will reportedly produce 100 Ml/d while the capacity of Sharqiyah project is yet undecided. Both projects are expected to go on stream within four years. They are intended to enhance the availability of potable water in the country's southern and northern regions. OPWP earlier floated another tender linked to the development of Salalah and Sahqiya independent water projects. More than 20 consultancies are understood to have submitted bids in response to a separate tender for conducting a topographic survey, a geotechnical investigation and a bathymetric and environmental survey to identify suitable locations for the Salalah and Sahqiya projects. The demand for potable water in Salalah is projected to grow at 8% a year as peak water demand grows from 75,000 m³/d in 2013 to 132,000 m³/d in 2020. The growth in demand for potable water is fuelled by population growth and industrial development, including tourism. In northern Oman, demand for water is forecast to grow 6% a year in the next five years to 349,000 m³/d in 2020. In 2014 OPWP forecast growth at only 3-5% in a seven-year outlook for power and water demand. The northern region is mainly divided into an interconnected zone and Sur zone. The interconnected zone includes Muscat, Al Batinah North, Al Batinah South and Buraimi in addition to Al Dhakhiliyah, Al Dhabirah and the Sohar Industrial area. Al Sharqiyah North, Al Sharqiyah South and Masirah are also in the zone.
