This client agency is a water agency responsible for managing the country's water supply, ensuring a sustainable and reliable water infrastructure, and promoting efficient water usage among residents, industries, and businesses.
The agency was looking to test out alternative underwater inspection solutions that could provide high-definition data for proper insights into their asset integrity management. They manage several pumps within a freshwater reservoir. Wrong pump orientations and leaks would affect the overall efficiency of the pumps and cause a build-up of siltation within the reservoir. Hence, inspecting these assets was crucial for the agency to ensure a continuous augmentation to the country’s water supply.
However, a clear problem that the agency dealt with was the data quality they would receive from other inspection services provided by human divers and Remotely Operated Vehicles (ROVs). As water within the reservoir was very murky, divers and ROVs struggled to locate pumps for inspection. Further, even if they were able to find these pumps, data quality captured by cameras carried by human divers and ROVs was too low in quality to provide meaningful actionable insights into the pump’s integrity.
BeeX was contacted by the agency to conduct a trial with autonomous inspection drone A.IKANBILIS. The objectives were to create a 3D point cloud visualisation of a pump less than a square meter in size, identify anomalies, and measure the degree to which the pump was tilting to provide insight into future repairs.
After being lowered into the water by the BeeX team, A.IKANBILIS swam from the reservoir’s jetty to the pump of concern located midway through the tidal barrage.
Despite low visibility at the reservoir, A.IKANBILIS was able to locate the tilted pump through sonar positioning. Then, the drone proceeded to capture clear visual footage enhanced by the autonomous inspection's image enhancement filters, and further created a 3D point cloud visualization of the pump.
These reports were geo-referenced and shown in real-time on BeeX’s Sambal User Interface for the client agency’s technicians to view.
After an hour of inspections, a compilation of all acquired visual and 3D footage was uploaded onto Sambal Portal, BeeX’s data reporting software. At the portal, appropriate analyses on the pump’s angle of tilt were performed through the software’s in-built measurement tools.
Watch: A.IKANBILIS Real-Time 3D Pump Scan
The deployment of BeeX's autonomous inspection drone A.IKANBILIS was an eye-opening discovery for the client agency.
Despite the challenging conditions of low visibility and high turbidity within the reservoir, A.IKANBILIS successfully conducted a detailed visual and 3D point cloud inspection of a crucial pump, which previous divers and ROVs were unable to perform.
This case was a true showcase of the power of autonomous underwater vehicles against older methods of underwater inspections.
