. Former GLDD CEO Dies September 11
At the end of June, Hall Contracting acquired Wommera, a Backacter 900, the largest Australian-owned backhoe dredge. The 65-meter (about 213-foot) Woomera has three bucket attachments - 18, 13 and 10 cubic meters (about 24, 17 and 13 cubic yards) - and a maximum dredging depth of 26 meters (85 feet). The buckets attach to the arm with pins, which are removed to change the bucket. This process takes about six to eight hours. The dredge was unveiled in Brisbane in late June. From there, it relocated north to Cairns for its first job at the Trinity Inlet shipping channel for contracting authority Ports North. The widening and deepening work, which is part of a larger $127 million development project at the port, began at the shipping channel at the end of July and was completed by the end of September. The Woomera is removing stiff clays from the inner harbor, which will be transported via barge to Port North's Tingira Street placement site. The Port of Cairns will use the material for beneficial use projects as fill for land development.
