Veolia awarded a multi-million dollar contract for a seawater treatment package for an offshore Guyana FPSO

Veolia Water Technologies, through its subsidiary VWS Westgarth Ltd, has been awarded a multi-million dollar contract by SBM Offshore for the supply of a seawater treatment package for the Liza Unity FPSO, located in the Stabroek block offshore Guyana.

The award is for the design and procurement of equipment with construction technical assistance for a seawater treatment plant sized for 263,244 BPD (41,856 m³/day) of low sulphate water and 31,700 BPD (5,040 m³/day) of reverse osmosis process water for the Liza Unity Floating Production Storage and Offloading (FPSO) unit, which will operate in the Liza Field, offshore Guyana. 

The seawater system, provided as two fully-integrated process modules, incorporates the sulphate reduction (SR) nano-filtration membrane process to selectively remove barium and strontium from the injected seawater, preventing the formation of barium or strontium scale in the reservoir or production pipe internals. The SR process leaves the other salts (sodium, chloride, etc.) substantially unaffected, maintaining the stability and permeability of the oil reservoir formation clays.

This is the twelfth contract awarded from SBM Offshore to Veolia and can be attributed to the successes of previous projects executed for the company. Liza Unity FPSO will be the largest capacity FPSO that SBM Offshore has designed. The FPSO will be spread moored in a water depth of 1,633 meters and will be able to store around 2 million barrels of crude oil.

VWS Westgarth is the world leader in sulphate removal systems, and has an impressive reference list in upstream water treatment applications. Many years of designing and building water treatment and desalination plants means that VWS Westgarth has a thorough understanding of water treatment processes. As part of Veolia Water Technologies, the company is able to utilise the specialist R&D and process abilities of the world's largest water treatment company.
