At north pine dam the SeaBotix LBV200 ROV was used to inspect 10 intake valves within a vertical riser shaft. At a depth of 30m the vertical riser turns 90 degrees to run horizontally over to the North Pine Dam Water Treatment Plant. AUS-ROV inspected the pipeline to 70m horizontal penetration to give SEQ Water’s engineers the opportunity to view the internal wall surface and inspect the main pipeline valve between the dam and the treatment plant. SEQ Water follow stringent inspection programs and have welcomed changes in available technology such as ROVs, allowing for a safer, more cost effective, non-traditional approach.
