WOODBRIDGE, UK — VWS Westgarth has commissioned Amarinth to manufacture two titanium API 610 OH2 pumps for the FPSO for Exxon Mobil’s Yellowtail development offshore Guyana.
This will feature six drill centers and up to 26 production and 25 injection wells, 200 km offshore and tied back to the One Guyana FPSO for processing.
The vessel will have an oil production capacity of 250,000 bbl/d and a storage capacity of 2 MMbbl, along with gas treatment capacity of 450 MMcf/d and water injection at 300,000 bbl/d.
Amarinth’s contract for the two titanium API 610 OH2 chemically enhanced backwash pumps follows its delivery of similar pumps to VMS Westgarth for two other FPSOs operating off Brazil.
To handle Yellowtail’s corrosive fluid, all wetted parts of the pumps will be manufactured in titanium, including casings, impellers and shafts. Titanium has to be cast under a full vacuum using copper crucibles to prevent the molten titanium attacking the crucible walls.
According to Amarinth, the UK has one of the world’s few foundries capable of casting the large titanium components needed for the API 610 OH2 pumps, which will be ATEX Zone 2 certified for hazardous areas with IECEx-certified motors.
As space on the One Guyana is limited, the design includes a special baseplate that incorporates a local control station within its footprint.
Lead time for delivery of the pumps is 38 weeks. Construction of the FPSO hull and integration with topsides modules is taking place in China.
