Japan's INPEX has successful completed the installation of the complex network of subsea infrastructure and equipment at the Ichthys LNG Project offshore Australia.

The milestone of laying 49 kilometres of umbilicals and flying leads marked the last placement of an intricate subsea network, spread across a 400 square kilometre area  of the Ichthys Field, in the Browse Basin, about 220 kilometres offshore Western Australia.

“Since October 2014, hundreds of people have worked offshore without any significant safety incidents to install the Ichthys LNG Project’s 133,000 tonne subsea network. Carrying out this work more than 200 kilometres out to sea in water depths of around 250 metres involves substantial planning and logistical challenges to manage crew changes and equipment transportation, “said Ichthys Project managing director Louis Bon.

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.

Once all commissioning activities in the South Korean shipyards are finished, the offshore facilities will be towed to the Ichthys Field and moored for their 40 year operational life by 40,000 tonnes of chain secured to more than 25,000 tonnes of foundation piles.
