Jeff. This is the rig that is to used in and around structures in the Yarra. In addition, just south of the Westgate bridge is a sewer line crossing the river and clearly excavating over this will be rather delicate, hence a rig of this order.
Thanks Grahme. I was being a bit tongue in cheek re the comments on the Queen of the Netherlands. I assume that the legs are wound down to give the dredging operation some stability and purchase? Not knowing much about dredging. JeffM
I photographed the Goomai today, she supposes to remove toxic waste from the Yarra bed , then this is transported in barges to a dumping ground in the bay after which clay will go on top, they refer to 2 million cubic metres .
I think we are talking a different structure. Have to find out which is the correct one.
Jan, I think my one is so small that it doesnt even have a name. It might have a number though. The Goomai looks as though it is a permanent rig on the barge, my one is a tracked excavator that can be wheeled on and off. I wonder if they work in tandem on the current toxic sludge project? Regards, JeffM
Jeff, As said I went there today and could only find the one I photographed, same barge worked on Saturdaynight when I passed in a launch and also today they moved a barge alongside in which the sludge was deposited.
I am intriged with your green coloured mini jack up, have to find out.
Jeff. Your green barge is capable of doing as I said, however Jans barge is I imagine capable of greater productivity. No doubt the green unit will probably be used around the structures up stream. Jans Goomai unit is directly above the sewer line I mentioned earlier.
