Japan’s Inpex informed that its US$34 billion Ichthys LNG project in Australia has landed three more subsea production manifolds on the seabed, bringing the total to four.
Good weather in the Ichthys field, located about 220 kilometres offshore Western Australia, allowed for the 435 tonne manifolds to be installed in around two days – landed within tolerances and ahead of schedule, the company informed in a statement.
When operational, five manifolds will commingle production from the subsea wellheads, distributing to the project’s central processing facility via 18 inch flowlines and flexible risers. This is part of a campaign to install more than 30,000 tonnes of subsea infrastructure and equipment across the field.
The Ichthys field is estimated to contain more than 12 trillion cubic feet of gas and 500 million barrels of condensate.
Gas from the field will be transported via the project’s 889 kilometre pipeline to Bladin Point near Darwin where an 8.4 mtpa LNG plant is being constructed.
