Abstract

In order to improve navigational safety and operational efficiency of vessels and to cater for larger ships with deeper draughts, the Port of Townsville conducts capital dredging. The port's capital dredging campaigns over the last 40 years has enabled deepening and widening of the existing inner harbor basin and approach channels, beside development of outer harbor. To determine the technical parameters of quantity, quality and types of materials to be dredged, the Port of Townsville undertakes hydrographic survey; offshore geophysical and geotechnical investigations that define dredging projects. While necessary to support the economic growth of the region, major port development works such as capital dredging have the potential significantly impact on the natural environment. To ensure the safety of the surrounding environment, the Port of Townsville has implemented integrated proactive approaches that consider environmental matters from capital dredging project planning and design stages. In accordance with relevant state and commonwealth regulations, the capital dredging material derived from the Port of Townsville may be placed at a designated ocean site or brought ashore for land reclamation. This paper provides an overview of the capital dredging at the Port of Townsville, with emphasis on geological setting, geotechnical investigations, capital dredging requirements, bathymetry, dredging methods/plant and dredged material placement options.
