EAST KILBRIDE, UK – VWS Westgarth is to provide seawater treatment equipment for Total’s CLOV FPSO in block 17 offshore Angola.
Daewoo Shipbuilding & Marine Engineering, which is assembling the hull in South Korea, requested an ultrafiltration system and a sulfate removal package (SRP). Both are due to be delivered next January.
They will be installed on the vessel’s topsides to treat seawater for subsea well injection. The ultrafiltration unit – the pre-treatment step to the SRP – will have a capacity to treat 391,288 b/d of water (66,208 cu m/d), while the SRP will treat up to 374,230 b/d (59,496 cu m/d).
According to VWS Westgarth, ultrafiltration equipment leads to a significant reduction in weight/footprint and improved water quality, compared with multi-media seawater filtration technology.
The SRP removes sulfates and other divalent ions from injection water, using Dow Filmtec membranes. Removal of the ions lessens build-up of barium sulfate and strontium sulfate scale in the reservoir, enhancing oil recovery.
