The potential Victorian site is at Crib Point, near Hastings, on Western Port Bay. We have had discussions with the Port of Hastings regarding the suitability of this site, which has an operating jetty already used to import liquid fuels.
Our work to date suggests the Crib Point site has some advantages, including:
Crib Point is not far from where a new container port had previously been proposed. That proposal has now been abandoned, but we can learn from it.
Concerns had been raised that a container port would require large amounts of dredging, result in several thousand ships visiting each year, and see thousands of trucks visiting each week.
As AGL’s proposed project would use an existing jetty and connect to the existing pipeline network, it would not require trucks to transport gas and would involve approximately 40 ship movements per year.
There may be a need to undertake some sweep dredging of the sea floor near the gas import jetty, similar to what is done in ports as part of routine maintenance programs.
Sweep dredging poses a small, temporary risk to vulnerable aquatic life and habitat in the immediate area of the jetty and will cause a small, temporary increase in the cloudiness of the water near the jetty. The process is far less disruptive than scoop dredging, which is required to deepen shipping channels and construct new ports.
Divers are doing sea floor surveys to see how much sweeping – if any – will be required.
The LNG ships that will deliver gas as part of AGL’s proposed project are generally 290 metres in length, longer than the container ships typically docking at the Port of Melbourne but considerably lower in height than fully-loaded container ships, which carry multiple layers of containers.
