Client:
Oil Search Alaska
Challenge:
Client required a floating seawater treatment plant to treat 100,000 bpd of water injection, which would meet the State of Alaska’s statutory and regional regulatory environmental requirements as well as be suitably winterized for the harsh climate of the North Slope of Alaska. The barge will be ABS class and will meet Arctic transportation weather windows as required for the overall project. The barge is scheduled for performance testing in Q2 2025.
VME Solution:
A new-build seawater treatment plant, to be constructed, transported, installed, commissioned, operated, and maintained for 25 years with hull classed to ABS Notation. The process facility shall be designed to deliver 100,000 BPD of treated Seawater to the Pikka development on the North Slope of Alaska at 1,100 psi. VME will perform the EPCIC with a dry tow from its yard in Asia pacific (Batam, Indonesia) to Harrison Bay in Alaska, with installation supervision and commissioning on site. The wet tow to be carried out by Oil Search Alaska.
