Faced with this challenge, the local transport authority authorized a large-scale $28.15 million coastal reconfiguration project. In order to keep the channel open and maintain an attractive and usable beachfront, frequent dredging of the seafloor along the harbor entrance is required. The harbor entrance has two seawalls, which over the years have accumulated severe sand and seaweed build up. Port Geographe is located in the town of Busselton in Western Australia. Guidance System Improves Dredging Performance

Met depth guidance parameters and rigorous design measurements.

HYDROpro software displayed the precise position of the cutter head under water within an accuracy of 10 centimeters.

CGC precise cutter head guidance allowed the dredge operator to dredge to the desired depth and return to the exact location where the previous day’s work ended this avoided wasted time and costly rework.

For the hydrographic survey, WAL avoided a multi-beam scanning operation.

The CGC team adopted the Trimble® HYDROpro™ Construction software, Trimble SPS461 GPS heading and positioning receivers WA Limestone (WAL) used Trimble GCS900 Machine Control on their excavators and a SPS855 receiver with HYDROpro Navigation on a Trimble Site Tablet and a single beam echo sounder on their hydrographic boat. With a tight deadline and specification to meet these goals, CGC turned to its technology partner SITECH Western Australia (WA) and Trimble for assistance. CGC was tasked with dredging the footprint to desired depths to prepare the seafloor for placement of rock for the new seawall. In addition, the port’s seawall structure had to be redesigned because it collected unmanageable levels of seaweed and sand. Dredging work establishes appropriate depths and keep the channel open to navigation. Port Geographe, located in Western Australia is a canal community and small boat harbor that requires regular dredging in order to cut back seagrass wrack and accumulated sedimentation collected on the seafloor. With operations beginning in 1980, CGC is extremely experienced and well respected in the industry with an established fleet of small to medium-sized cutter suction dredges.

CGC Dredging is a specialist dredging company based in Western Australia that has expertise in mine tailings and marine dredging industries.
