The job involved deepening the navigational channel and placement of the material behind &#8220;Kirby&#8217;s Wall&#8221;.<\/p>\n<p>Neumann Dredging performed the work using their 450mm Cutter Suction Dredge Nu Endeavour coupled to a spreader barge for placement.<\/p>\n<p>The work was required following recent severe flooding, with joint funding provided by the Qld Department of Transport and Main Roads and the Department of Natural Resources and Mines.<\/p>\n<p>The Burnett river was severely impacted by flooding in January 2013. Dredging was required to restore the depth of the river\u2019s navigational channels adjacent to Kirby\u2019s Wall. A total of 65,700 cubic metres of sand and gravel was removed from the channels and placed behind Kirby\u2019s Wall.<\/p>\n<p>Two specific dredge areas were nominated by TMR:<\/p>\n<ul>\n<li>Dredge Area A, adjacent and upstream of Kirby\u2019s Wall required 36,000m3 of material to be removed, and<\/li>\n<li>Dredge Area B, downstream of Kirby\u2019s Wall with almost 30,000m3.<\/li>\n<\/ul>\n<p>Both dredge areas were required to be dredge to a maximum depth of 2.3m below LAT.<\/p>\n<p>The dredged material was required to be placed behind Kirby\u2019s Wall to fill in the area between the river bank and the rock wall. The material was spread evenly to a height below +0.3 LAT<\/p>\n<p>Equipment Used<\/p>\n<ul>\n<li>Dredge &amp; Booster &#8211; The 450mm cutter suction dredge the Nu Endeavour was used for this project. A booster pump and pontoon was connected directly to the rear of the dredge to extend its pumping capability to reach the required distances to the disposal area (up to 1,700m).<\/li>\n<li>Spreader Barge &#8211; A spreader barge was used behind Kirby\u2019s Wall with a three wire anchoring system. This allowed the spreader barge to winch across the fill area while the material is being discharged. Floating pontoons was employed adjacent to Kirby\u2019s Wall to ensure anchor lines didn\u2019t come into contact with the top of the wall and cause damage.<\/li>\n<li>Support Vessels \u2013 Other supports vessels included: a Workboat, the MV Tramp; Fuel Barge; Anchor Barge and a number of smaller tender vessels.<\/li>\n<\/ul>\n<p>Dredging Works<\/p>\n<p>Dredging commenced at the upstream end of the channel and progressed downstream. Additional pipeline was added for works in Dredge Area B.<\/p>\n<p>The project was completed on a 24 hour, 7 day per week basis.<\/p>\n<p>Innovations<\/p>\n<ul>\n<li>Use of spreader barge to place the dredged material behind Kirby\u2019s Wall<\/li>\n<li>Use of a barred Bucketwheel to exclude oversize material from the pumping system<\/li>\n<\/ul>\n<p>Challenges<\/p>\n<ul>\n<li>Spreading the dredged material evenly and with tolerances with the spreader barge behind Kirby\u2019s Wall<\/li>\n<li>Post flood debris and obstructions in the dredge area<\/li>\n<li>Dredging unpredictable material \u2013 coarse sand, gravel, cobbles and boulders.<\/li>\n<li>Wear and tear on machinery and equipment.<\/li>\n<li>Strict dredging and fill tolerances.<\/li>\n<li>Interfacing with shipping and other marine vessels.
