In 2002, the Geraldton Port Authority (GPA) embarked on a $100M upgrade program which included the dredging of approximately 5 Mm³ of predominantly rock material from the 5 km entrance channel and basin.
The initial dredging works involved the removal of contaminated material (approximately 150,000 m³) from the basin with small cutter suction dredges and placing it in a lined disposal site.
The main dredging campaign followed with the Cutter Suction Dredge (CSD) Leonardo Da Vinci (the largest CSD in the world at the time), involving the removal of rock materials from the channel under extreme swell conditions from the exposed entrance channel.
Dredged material under this contract was disposed of at 3 offshore sites in accordance with the approved Sea Dumping Permit.
Additional works carried out during the project included navigation aid construction and installation, modifications to shiploaders, berths and outloading systems.
We were engaged by the Bunbury Port Authority in 2004 and again in 2007 to manage maintenance dredging works undertaken in the harbour and channel areas of the Port.
With our expertise in port planning and close knowledge of Western Australian ports, we provided port expansion options, dredging and construction solutions, and cost estimates for construction and facility operations.
We prepared a business plan for the new offshore multi-user port development in Abu Dhabi, involving staged construction of facilities from initial operations in 2010 to full development by 2028.
We prepared a detailed demand assessment to identify the product mix and potential industry clusters that drive the cargo throughout the client's ports in China.
