The dredging team placed the sand on the foreshore at Cabbage Tree Point, adjacent to the channel.<\/p><p>Significant sand deposition and shoaling within the Main Channel North necessitated dredging to maintain safe navigable depth. This channel forms the primary movement channel for vessels travelling between Moreton Bay\u2019s northern and southern areas. Therefore, it is vital to maintain navigable depths under all tidal conditions. The build-up of sand reduced water depths within the defined navigation channel at low tide to under one metre in some areas. Beach nourishment for recreational amenity was the selected dredge material management option to improve the amenity of the foreshore and provide additional protection to the land, which has been subject to steady erosion.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-746a3cf elementor-widget elementor-widget-heading\" data-id=\"746a3cf\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Scope of Works<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d1b6ff5 elementor-widget elementor-widget-text-editor\" data-id=\"d1b6ff5\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<ul><li>The mobilisation of a 250mm cutter suction dredge, the Nu Discovery, and 500m of 250mm poly pipeline.<\/li><li>Dredging of 15,000m3 of marine sediments for the main channel.<\/li><li>Pumping the sediment through the pipeline to the deposition site adjacent to the channel.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4778f2c elementor-widget elementor-widget-heading\" data-id=\"4778f2c\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Challenges<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-dbaf166 elementor-widget elementor-widget-text-editor\" data-id=\"dbaf166\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<ul><li>Strict environmental guidelines.<\/li><li>Maintaining suitable access through the channel and maintaining access to the busy boat ramp.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5140628 elementor-widget elementor-widget-heading\" data-id=\"5140628\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Nu Discovery CSD Used for this Project<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-589d2198 elementor-widget elementor-widget-text-editor\" data-id=\"589d2198\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span style=\"font-size: 16px;\">The Nu Discovery is a 250mm cutter suction dredge from the <\/span><strong style=\"font-size: 16px;\">Nu Explorer<\/strong><span style=\"font-size: 16px;\"> series of dredges.
