Hydro Tasmania contacted us for a project on one of their dams. Due to the recent flooding events that have hit all of the eastern and southern coast of Australia (a 1 in 200 year event), a significant volume of water was flowing into the northern lakes, discharging over several spillways Hydro Tasmania own and operate.
Due to the high resolution scanning ability of the Kongsberg MS1000, we were able to show extremely clear images of the dam structure that hadn't been seen in almost 60 years since the dam construction. Due to the water being almost Zero Visibility, prior commercial dives in the dam plunge pool only hinted at various issues underwater, the sonar imagery we collected allowed the Engineers and Hydrographers to see everything that was occurring.
Despite the environmental conditions, we completed the project without getting too wet and cold, and were able to provide a mosaic of the scans (as above) by the end of the day. The sonar scans gave Hydro Tasmania's engineers very useful information to assess the condition of the dam plunge pool..
