The "David Allen" Dredge - Newcastle Harbour NSW Australia by 


707 views as of 6th December 2010

The David Allen is a split-hopper trailer suction dredge and is used in the maintenance of the channels and the berthing trenches in the Port of Newcastle, NSW Australia.

Its prime function is to maintain the required depth so there is no shortening up of the depth of water of the ships entering or exiting the port.

The dredge is 70 m long, 15 m wide with a 12 m loaded draft. Each load is about 1400-1500 tonnes, with about one third of that being of solid material and is picked up through a centrifugal pump which is in the middle of the drag arm that trails off the starboard arm. The load is taken to a designated spoil ground located 1.5 nautical miles south east of Nobbys. (this info taken from http:www.newportcorp.com)

The image was taken on the 12th August 2009 using the Nikon D70S, 50-500 mm lens, fully extended and was shot from Stockton near the start of the breakwall. You will note the famous Newcastle landmark, Nobby’s Lighthouse in the background with the newly restored WWII observation bunkers on the left and at the base of the cliff.

    Interesting shot, Phil. And tremendous clarity for a 500mm pic.

  • Dohmnuill, the dredge operates 24/7 to ensure the creek has the appropriate depth for the new additions to the coal loading facilities at Newcastle. Camera experts tell me the lens when wound right out on a Nikon D70s is much longer than 500MM. Obviously, I used a tripod. Thanks for the comment.

  • Ken, we often have whales passing close by the entrance to Newcastle Harbour. Despite the constant dredging further up the river, the condition and clarity of the water in the harbour is extremely good. Many thanks for the feature.
