What is the area of land required for shore crossing?
A shore crossing for an LNG facility at the Precinct is critical for the operation of the
facility. The shore crossing across the beach and associated corridor connecting it to the
main LNG facility is required to carry several important pieces of infrastructure. There are
two types of corridors required for the LNG Precinct. The first is for the pipelines coming
from the gas fields offshore and include:
� Multiple large pipelines that carry the gas and liquids in from the gas field (and
offshore facilities). As these are high pressure gas pipelines they need to meet
appropriate safety requirements to ensure they are appropriately separated from
each other; roads and areas of public access.
� Return lines that pump the chemicals recovered from the liquid stream back offshore
to the gas fields. This primarily consists of Monoethylene Glycol (MEG) which is an
anti-freeze very similar to what is put in car radiators in colder climates.
The large pipelines need to cross the shore a safe distance from the area that ships will
operate in to maintain safety of the facilities.
The second type of corridor is for the loading the LNG onto ships and connecting the
LNG facilities to the Materials Offloading Facility (MOF). The items in this corridor include:
� LNG loading lines are required to carry the LNG from the tanks to the ship and gas
(LNG) vapour from the ship back to the LNG facility. Consequently two lines are
needed for each berth;
� Condensate (light oil) loading lines are required to load the condensate from the
storage tank out to the loading berth;
� Liquefied Petroleum Gas (LPG) loading lines need to be allowed for in case a future
proponent produces LPG if it needs to be removed from the gas to meet the LNG
specification requirements;
� A haul road is needed to connect the Materials Offloading Facility to the LNG plant
to carry the large modules (potentially up to 10,000 tonnes) up to the LNG facility.
This haul road requires about 75 metres (82 yards) of width);
� Access road to the jetty for workers and maintenance equipment;
� Various other utilities also need to be supplied including power, water,
communications, etc.
As the Precinct is designed to be expanded in the future the corridor and beach crossing
has to allow enough room for the facilities that will already be operating and the
installation of the new facilities to support expansion while the existing facilities remain in
use. For example when a new pipeline from the sea is pulled ashore this cannot occur
too close to an existing pipeline that is already operating so that the safety of the workers,
community and environment is maintained.
