Gorgon, NW Australia
A breakwater is being built for the Gorgon LNG terminal in North West Australia. The breakwater will be armoured by a large number of Xbloc armour units.
The production of the Xblocs is carried out by BAM Decorient, Indonesia. The Xblocs are produced in the port of Cigading, Java, and loaded onto barges which transport the Xblocs to Australia. The breakwater for the LNG terminal in NW Australia has two purposes, it is the causeway leading to the LNG jetty and it provides shelter for the tug berths. Xbloc placement is done by Thiess and Boskalis.
