Newcastle Celebrates 160 Years of Continuous Dredging

Port of Newcastle is celebrating 160 years of continuous dredging and its vital role underpinning safe and reliable operations as Australia’s third-largest port and the world’s largest coal export port.

Continuous dredging of the channel began in March 1859 using ladder dredges to remove mud, sand, boulders and surface rock to ensure the safe passage of ships.

These days, safely and reliably managing thousands of ships a year depends heavily on the work of the 70-meter David Allan dredger, which operates 12 hours per day, seven days a week.

The David Allan is tasked with maintaining a channel depth of 15.2 meters along a nine-kilometer stretch from the breakwalls to the Kooragang 10 berth in the river’s South Arm.

Port of Newcastle dredge manager Calvin Grills said that it was important to acknowledge and celebrate the role of this maintenance dredging in the success of Port of Newcastle as a global trade gateway.

Tens of thousands of ships, collectively transporting several billion tonnes of cargo, have navigated the channel over the past 160 years,” Mr Grills said. “This international trade in steel, coal, fuels, grains and other important cargoes has only been possible because the channel has been kept clear, enabling New South Wales businesses to be globally-competitive.

Silt build-up is a natural part of the Hunter River’s normal function. Much of the silt dredged from the Newcastle harbor comes from the North Arm of the river, which is broader and shallower than the South Arm.

The particles are carried along more quickly, before much of it is dumped in the slow sweep of the river off Stockton known as the Horseshoe.

Russia’s leading maritime industry Media Group PortNews ( holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
