July deadline for Adnoc water PPP project

Developers have been invited to submit proposals for first phase of ‘Project Wave’

Abu Dhabi National Oil Company has extended the bid submission date to 18 July for the project to develop a seawater nanofiltration plant at Al-Mirfa, the first phase of the estimated $5bn ‘Project Wave.’

Energy & Utilities reported in November that 11 groups had been prequalified to participate in the tender for the planned public-private partnership (PPP) project to develop nanofiltration plants at Al-Mirfa and Al-Nouf. Adnoc decided to split the ‘Project Wave’ scheme into two phases, with the Al-Mirfa phase tendered first.

The projects are planned to be developed under a build, own, operate and transfer (BOOT) basis.

The 11 firms prequalified as managing members for Project Wave are:

  • Acciona Agua (Spain)
  • Acwa Power (Saudi Arabia)
  • Cobra Instalaciones Servicios (Spain)
  • FCC Aqualia (Spain)
  • Hutchinson Water International Holdings (Singapore)
  • IDE Water Assets (Israel)
  • Itochu Corporation (Japan)
  • JERA (Japan)
  • Marubeni Corporation (Japan)
  • Six Construct (Belgium)
  • Veolia (France)

Energy & Utilities reported in March 2021 that Adnoc had appointed the local office of Austria’s ILF Consulting Engineers as technical adviser for Project Wave. Sumitomo Mitsui Banking Group (SMBC) and Alderbrook were appointed as financial advisers.

The project will involve the development, financing, construction, operation and maintenance of two standalone greenfield seawater nanofiltration plants with a combined treatment capacity of 210 million imperial gallons a day. The project will also involve the construction of pumping stations and transmission pipelines to transport the treated water to onshore fields, which will require approximately 450km of new pipeline infrastructure.

The project has been designed with the intention to replace the current aquifer water injection systems used for maintaining reservoir pressure in onshore fields in Abu Dhabi with more sustainable water resources. The plant also forms part of Adnoc’s strategy to reduce carbon emissions in its development activities, with the scheme expected to increase efficiencies and lead to a net reduction in CO2 emissions.

The successful bidders will form a special purpose vehicle (SPV) with Adnoc to deliver the BOOT scheme, with a long-term water treatment and transportation agreement (WTTA) to be signed between the SPV and Adnoc, the offtaker for the scheme. The project will be fully returned to Adnoc at the end of the WTTA.
