| Work Detail |
Veolia Water Technologies, through its subsidiary VWS Westgarth, has secured a contract from SBM Offshore for the supply of a seawater treatment package to the Liza Unity Floating Production Storage and Offloading (FPSO), which is located offshore Guyana.
Under the multi-million dollar award, the subsidiary will be responsible for the design and procurement of equipment as well as for providing construction technical assistance for a seawater treatment plant.
The plant will have a capacity of 263,244 BPD of low sulphate water and 31,700 BPD of reverse osmosis process water for the FPSO unit.
Situated in the Stabroek block, this FPSO will operate in the Liza Field.
Under the contract, the seawater system will be offered a two fully-integrated process modules.
The system will feature the sulphate reduction (SR) nano-filtration membrane process. This helps to selectively eliminate barium and strontium from the injected seawater and prevent the formation of barium or strontium scale in reservoir and production pipe internals.
Furthermore, the SR process enables other salts such as sodium, chloride, etc., to remain unaffected, thereby maintaining the stability and permeability of the oil reservoir formation clays.
This is the 12th contract awarded by SBM Offshore to Veolia.
Liza Unity FPSO will be the largest capacity FPSO designed by SBM Offshore. It will be moored in a water depth of 1,633m and will be able to store around 2 million barrels of crude oil.
VWS Westgarth specialises in sulphate removal systems. Veolia Water Technologies offers a range of services for the design, delivery, maintenance, and upgrade of water and wastewater treatment facilities and systems for industries and public entities. |
