Veolia to supply water treatment system module for Woodside FPSO
EAST KILBRIDE, Scotland -- Veolia has been awarded a multi-million dollar contract for the supply of the customized water flood water treatment system on the Ngujima-Yin Floating Production Storage and Offloading (FPSO) facility that will operate in Woodside’s Greater Enfield Area Development fields, offshore northwest Australia.
The Ngujima-Yin FPSO is a 332-m double hulled tanker built in 2000 and converted into an offshore production facility to produce oil from Vincent oil field. Once separated from gas and water, crude oil extracted from the reservoir is exported from the FPSO onto trading tankers.
The award is for the design, equipment procurement and supply, and construction as a single lift integrated process module, incorporating: coarse filtration, ultra-filtration (UF) pre-treatment, sulphate removal membrane process (SRP), vacuum deaeration, dual fuel turbine driven water injection pump, electrical switchgear and transformers, and plant control room. The system water injection capacity is 12,720 m3/day (80,000 bwpd), with a turndown capacity to 8,745 m3/day (55,000 bwpd).
The heart of the system is the specialized SRP membrane process that is designed to remove sulphates and other divalent hardness ions from injection water used in enhanced oil recovery water flood operations. The removal of these ions reduces the tendency of barium sulphate and strontium sulphate scale to form in the reservoir and flowlines, plus prevent well souring by controlling sulphate reducing bacteria.
