The central processing facility (CPF) processes the product received via the flexible risers from the production wells, separating it into gas and condensate.
The CPF measures approximately 110m by 150m, making the semi-submersible facility one of the largest of its kind in the world. The facility will have a peak gas export rate of 1,657 million standard cubic feet per day.
The floating production storage & offloading (FPSO) facility receives condensate from the CPF, which it stores and offloads onto tankers for shipping and export.
The FPSO is 336m long and 59m wide, and is designed to hold more than one million barrels of condensate. 85,000 barrels of condensate stored per day at peak will be shipped from the FPSO.
The onshore gas liquefaction plant extracts condensate and LPG from the natural gas delivered by the pipeline, and cools and liquefies the remaining natural gas. Annual production and shipments from the gas liquefaction plant are scheduled to amount to approximately 8.9 million tons of LNG and approximately 1.65 million tons of LPG, in addition to approximately 15,000 barrels of condensate per day at peak.
The subsea production system collects the product extracted from production wells in the production manifold, and from there sends the product to the CPF via flowlines and flexible risers.
The Ichthys gas-condensate field is a liquid-rich gas and condensate field. Approximately 100,000 barrels per day at peak will be shipped from the FPSO and the onshore gas liquefaction plant, one of the largest production quantities among oil and gas fields in Australia today.
The Ichthys LNG Project is scheduled to produce approximately 8.9 million tons of LNG per year, equivalent to approximately 10% of Japan’s annual LNG import volume. Approximately 70% of the LNG produced will be shipped to Japanese buyers.
A pipeline 42 inches in diameter extends over a distance of approximately 890km, connecting the CPF with the onshore gas liquefaction plant. The water along the route goes as deep as 250m.
