Veolia Water Technologies, through its subsidiary VWS Westgarth Ltd, has been awarded a multimillion-dollar contract by SBM Offshore for a seawater treatment package for the Liza Unity Floating Production, Storage and Offloading (FPSO) oil platform in the Stabroek block offshore Guyana.
According to www.worldoil.com, the award is for the design and procurement of equipment with construction technical assistance for a seawater treatment plant sized for 263,244 bpd of low sulphate water and 31,700 bpd of reverse osmosis process water for the Liza Unity FPSO unit.
The seawater system, provided as two fully-integrated process modules, encompasses the sulphate reduction (SR) nano-filtration membrane process to selectively remove barium and strontium from the injected seawater, preventing the forming of barium or strontium scale in the reservoir or production pipe internals. The SR process leaves the other salts (sodium, chloride, etc.) substantially unaffected.
This is the twelfth contract awarded from SBM Offshore to Veolia, the report said, noting that the Liza Unity FPSO will be the largest capacity FPSO that SBM Offshore has designed. The FPSO, it said, will be spread moored in a water depth of 1,633 meters and will be able to store around 2 MMbbl of crude oil.
