SBM Offshore has awarded a multi-million-dollar contract to Veolia Water Technologies, through its subsidiary VWS Westgarth Ltd. to supply a seawater treatment process module for the massive ‘One Guyana’ floating production storage and offloading vessel.
The vessel will be used for ExxonMobil’s fourth development in the Stabroek Block – Yellowtail – offshore Guyana.
Veolia said on Wednesday that the contract award is for the design, procurement, and supply of equipment to process 15,350 cubic metres per hour (m3/h) of seawater fresh water, and low sulphate water injection. The nano filtered low sulphate seawater injection is supplied at up to 2,092 m3/h and fresh water supplied from seawater reverse osmosis (SWRO) at 350 m3/h.
The company said that the seawater system is provided as a single, fully integrated process module comprising coarse filtration, UltraMEV108 ultrafiltration pre-treatment, sulphate removal membrane process, SWRO membrane process, membrane clean-in-place unit, vacuum deaerator unit, water injection booster pumps with system piping, valves, and instrumentation.
“Low sulphate seawater is injected into the oil-bearing reservoir to maintain pressure and improve secondary recovery, this helping to ensure that the oil production is achieved as efficiently as possible, and minimising the operations carbon footprint,” Veolia said.
It will be the company’s 14th Sulphate Removal Process (SRP) technology project with SBM Offshore, and 3rd for Stabroek Block, building on the successful SRP process modules design, supply, and operations support services provided for the Liza Unity and Prosperity floating production, storage and offloading vessels (FPSOs).
‘One Guyana’ is based on SBM Offshore’s Fast4Ward® program that incorporates the company’s new build, multi-purpose floater hull combined with several standardised topside modules.
The vessel is being designed to produce 250,000 barrels of oil per day, with an associated gas treatment capacity of 450 million cubic feet per day and water injection capacity of 300,000 barrels per day. The floater will be spread-moored in water depth of about 1,800 metres and will be able to store around two million barrels of crude oil.
Already, the hull for the floater has been completed and is sitting in Indonesian waters, waiting to travel to the Keppel shipyard in Singapore for assembly.
The project’s turnkey phase is being executed in conjunction with United States engineering and construction company, McDermott, under a special purpose company. In it, SBM Offshore holds 70% and McDermott 30% equity ownership. But the FPSO will be fully owned by SBM offshore.
