Why ports need to dredge

1 Comment


Dredging is the term given to removing material from waterways to deepen channels, create harbours, and keep channels and approaches to ports at defined depths. Dredging is a vital part of operating a safe and efficient port. Dredging can either be capital dredging (new channels and berths) or maintenance dredging (necessary to maintain existing and approved dredging areas). Dredging is highly regulated and is subject to strict State and Commonwealth legislation. Contaminated material is not allowed to be placed at sea. All material for ocean relocation is tested under rigorous requirements set out in the National Australian Guidelines for Dredging (NAGD) using accredited laboratories. The Commonwealth Government also engages independent experts to review applications to place material at sea
