Opened in 2000, the East Arm Wharf is a 750 m long facility located in Darwin Port. The largest facility on Australia’s north coast, the facility is capable of accepting vessels up to 80,000 tonnes, with a maximum draft of 15 m. The Wharf comprises a bulk liquid berth, a common user facility, a container facility and a bulk loading berth. The container berth is served by a rail-mounted container crane with a heavy lifting capacity of 70 tonnes at 10 m outreach.
PSM was engaged to provide specialist advice on several complex geotechnical issues associated with wharf construction.
A huge tidal range of 7.8 m has resulted in a very high wharf face. Construction of the wharf structure on existing bund built from materials under water, makes it susceptible to deformation.
Other engineering and technical opportunities included:
PSM’s tailored approach included:
PSM’s involvement enabled resolution of key technical challenges and completion of structure without incident. As a result of ongoing monitoring the client is able to manage risks relating to time-dependent deformation of the geotechnical materials used in the wharf’s construction.
