Berth upgrades
A consequence of deepening the shipping
channels and accommodating larger vessels is that modifications,
such as structural upgrades, are required on the infrastructure at
shipping berths in the Port of Melbourne.
Bank protection works are also required along the Yarra River
and Williamstown Channels to maintain stability of the river banks
and the infrastructure along it.
Swing basin expansion
Increased ship size mean that the existing
swing basin (where ships turn around when leaving or entering the
docks) must be widened to the north and south in order to increase the
swing basin diameter and maintain vessel safety in the Port.
Services protection
Five service and utility lines are located under the Yarra River
Channel, including, the Melbourne Water Hobsons Bay Main Sewer, oil
and gas pipelines and telecommunications and electricity network
cables.
In addition to the above, an ethane pipeline crosses under the
existing fairway within the extent of the southern extension of the
Port Melbourne Channel.
As the CDP requires a reduction of the thickness of material
overlying these services, protection measures, such as steel plate
covers and grouted rock barriers, will be installed to reduce the
potential for damage to services from shipping movements.
Installation /
upgrade of Navigational Aids
Navigational aids are somewhat like the white markings on a road,
they provide the ships navigators the operational boundaries of the
shipping channel, to ensure the safe navigation of vessels through
Port Phillip Bay. To ensure the ongoing safe navigation
of vessels in the deepened shipping channels, the installation of
new navigation aids and upgrades to existing navigation aids will be
undertaken. |
