The final laying of 49 km of umbilicals and flying leads, marked the last placement of a subsea network, spread across a 400 km² area of the Ichthys field. Included in the extensive subsea gathering system is a 110-metre-high riser support structure, five manifolds, 139 km of flowlines, 49 km of umbilicals and flying leads, five subsea distribution units and a subsea distribution hub.   

“Finalising the subsea installation, a key milestone, signified the project was now ready for the arrival of the central processing facility (CPF) and floating production, storage and offloading (FPSO) facilities, currently under commissioning in South Korea,” a company statement said.

The Ichthys LNG project is a joint venture between Inpex (the operator), Total, CPC Corporation Taiwan and the Australian subsidiaries of Tokyo Gas, Osaka Gas, Kansai Electric Power, Jera and Toho Gas. The project is expected to produce 8.9mn mt of LNG and 1.6mn mt of LPG annually, along with more than 100,000 barrels of condensate/day at peak.
