3. CPF Design

The CPF is a column-stabilized, offshore semi-submersible production unit supporting
hydrocarbon processing systems and utilities, as well as living quarters for about 200 people.

INPEX’s CPF will be the world’s largest semi-submersible platform. It is being constructed in
South Korea at the Samsung Heavy Industries shipyard.

Once constructed, the facility will be towed about 6,000 kilometers to the Ichthys Field in the
Browse Basin, offshore Western Australia. It will be permanently moored near the Field for the
life of the Project by 28 mooring lines, representing more than 25,000 tons of anchor chain.

The main dimensions on the hull are given from Table 1 to Table 3 as follows.
