Drones monitor 27 kilometers of water pipeline in Sydney

Sydney used drone monitor several kilometers of water pipelines. Thanks to drones and large amounts of data, this company has made this task easier. 80% of Australia's largest city's water is transported by two pipes laid on the ground through a dam built in the narrow gorge of the Wallagamba River.

Ensuring that such an important infrastructure is kept in top condition is a daunting task: There are a large number of pipelines that may crack, leak or corrode over a length of more than 27 kilometers. Therefore, it is not surprising that inspection and monitoring of this pipeline (called the Warragamba pipeline) is an important and arduous task.

Traditionally, completing this task requires staff to go to the site for manual inspections-a task that is both time-consuming and laborious. AUAV is a Melbourne-based drone service company that specializes in measurement, inspection and 3D modeling.

"This project is a challenge," admitted AUAV Director James Rennie. "This is definitely pushing the boundaries of large-scale data capture at the micro and micro scale." In the past eight years of operation, AUAV has conducted more than 50,000 drone flights and is very good at processing large amounts of data. Modeling the Warragamba pipeline means processing large amounts of data.

"We ended up with 118,000 photos, and all of them were just over 20 megapixels," Rennie said. "We are talking about terabytes of data." All of this data is used to create a 3D model of the entire length of the pipe, which is accurate to the sub-millimeter level. "In hindsight, it was a bit crazy," Rennie said. "The real technical challenge of this project is the amount of data. Therefore, there are not too many projects of this size. It is very valuable to be able to absorb a large amount of data and produce something very useful to customers."

FlyDragon FDG25 fixed -wing vtol for pipe inspection

long endurance drone 3 hours VTOL V tail for mapping surveillance

FDG25 long endurance drone with vertical take-off and landing fixed wing, wingspan 2.5 meters,it iss electric version . This model combines the characteristics of long-endurance, high-speed and long-distance of fixed-wing UAVs and the vertical take-off and landing of rotor-wing drones. The fuselage is designed as quick release structure, with reliable electrical connection, plug and play; unfolding and withdrawal time is less than 10 minutes. The engine is rear-mounted and the load is placed forward to provide a larger field of view for the photoelectric load without obstruction.
