The INPEX-operated Ichthys LNG project’s central processing facility (CPF) has been safely moored in the Ichthys Field, some 220 kilometres off the north coast of Western Australia, where she will be located for 40 years.

The massive CPF, named the Ichthys Explorer, is the world’s largest semi-submersible platform, weighing 120,000 tonnes and with a topsides footprint measuring 130 metres by 120 metres.

The CPF is the central hub for initial offshore processing of all well fluids delivered from an extensive, 130-kilometre network of subsea well infrastructure.

Gas from the CPF will be sent through an 890-kilometre subsea pipeline to the onshore LNG facility, at Bladin Point, near Darwin for processing. Condensate arriving to the CPF will be transferred to a nearby floating production, storage and offloading facility (FPSO), the Ichthys Venturer.
