Dredging in the Port of Gladstone has occurred since the 1960s, and is a vital part of operating a safe and efficient port.
Dredging is required to create new or deeper channels and berths for ships, and to maintain the depth in channels, berths and harbours to enable a safe passage,
In the last three decades, the expansion of port facilities and other industries have been strategically planned to maintain a balance of industrial development, protection of the environment and a sustainable fishing harbour.
Fact Sheet: Why Queensland Ports need to dredge
Dredging is sometimes necessary as a part of our strategic plans and development projects:
Maintenance dredging is a routine part of our port operations to ensure the safe operation of shipping in our harbour. It involves the removal of sediments that have built up in existing channels, berths, approaches and associated swing basins.
At times, GPC disposes of maintenance dredge material at sea at the approved East Banks Sea Disposal Site in accordance with our Sea Dumping Permits issued by the Commonwealth Department of the Environment. Other approved land based reclamation areas are also utilised for the disposal of dredge material.
Our Monitoring and Management Plans describe the actions that GPC undertake to ensure that our maintenance dredging activities are undertaken in an environmentally responsible manner.
Permit Period 01 December 2015 to 01 August 2018:
Marina Maintenance Dredging Program
The Marina Maintenance Dredging Program is required to return the Marina berths to an acceptable depth to enable safe entry and exit, and minimise potential damage to vessels. The ideal depth for the Marina is 3 to 4 metres LAT (Lowest Astronomical Tide), with current depths at 1 - 1.5 metres LAT.
Port of Bundaberg
As part of the Port of Bundaberg Maintenance Dredging 2014 campaign, GPC is committed to the implementation of the approved Sediment Sampling and Analysis Plan (SAP), 2014 and 2019, as presented in the Long Term Management and Monitoring Plan (LTMMP) for Maintenance Dredging and Disposal, Port of Bundaberg 2012–2022 (Worley Parsons, 2010).
