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..

We have recently conducted underwater and aerial condition assessments for 5 SEQWater potable reservoirs in Alexandra Hills, Narangba, and Ferntree in South East Queensland for GHD. The 5 potable water tanks were inspected over the course of three days, with strict sterilisation procedures being followed for all equipment entering the reservoirs. As per our standard operating procedure whenever operating with potable water, all equipment was sterilised with 200ppm active chlorine and left to soak for a minimum of 30 minutes, including the ROV, all tether, ropes and tarps that were used to keep the ROV and equipment clean on the base as well as the roof of the reservoirs. Our High Definition Seamor ROV enabled the GHD Engineers to confidently assess the underwater internal structures of the reservoir, including ladders, wall and floor joins, scours, probes, mixers, columns, and also any buildup of debris or sediment. All of the inspections were completed on time and within budget, thanks to the organisation and planning from Rhett and Danny from GHD, as well as Russell from SEQWater. We look forward to conducting more inspections for them in the upcoming months.
