The jetty is likely to be built using piles anchored to the seabed into the rock. The spacing
and number of piles will depend on the final configuration of the jetty. The requirement for
piles will be broadly similar for both north and south of James Price Point options.

Question ñ What type of jetty will there be and what is the expected size?
The jetty design is influenced by the geological and seabed conditions and the distance
to deep water. Differences in the marine environment to the north and south of James
Price Point are very significant and will influence the concept that is adopted.
Each proponent would have its own jetty. This is driven by:
� Safety considerations from events that could occur due to another operator;
� Uncertainty over the jetty design requirements for future proponents.
A single jetty for three berths is sufficient to meet the foundation proponentís
requirements. The export of 50 million tonnes per annum of LNG from the Precinct will
require six berths, and the number of jetties will be dependent on the number of
proponents.
If a jetty structure is used it is likely to be an open trestle structure supported on driven
steel piles anchored into the rock below the seabed. The height of the jetty will be set to
avoid overtopping in any cyclone or other extreme event. The jetty itself will provide a
single traffic lane and a series of pipelines for LNG and condensate loading as well as
return gases and vapours.
A key focus for the port and jetty design will be to minimise the footprint/area required
(particularly for the coastal crossing) as far as practicable.
