TasNetworks has awarded Fugro a new contract to deliver a 3D virtual network model and associated analytics for their power distribution network in Tasmania.

Fugro will create a ‘digital twin’ of the distribution network by capturing aerial lidar and imagery data and processing it using cutting-edge machine-learning and cloud-computing systems. The company started the project to acquire data in December 2020 and delivered its first data sets last month.

From here, TasNetworks representative will then be able to analyse the data and execute detailed engineering and vegetation clearance analysis using Fugro’s Roames World cloud-based platform.

Vegetation that comes into contact with powerlines can ignite fires, so Fugro’s data will be essential for managing and mitigating bush fire risk around the network.

As part of the project, Fugro will also perform an image-based condition assessment of the pole tops in selected high-outage areas, such as those exposed to extreme winds and salt spray. High-resolution imagery of the poles will be captured from helicopter-mounted cameras and combined with automated data analytics, again via Fugro’s Roames World. Images will be analysed to quickly identify damaged or corroded components, prompting immediate action and informing longer-term asset maintenance and replacement plans.

“Helicopter checks are crucial for spotting defects and keeping powerlines as secure as possible and Fugro’s virtual model of our network will generate actionable insights for us to take preventive measures,” TasNetworks general manager of network, commercial and major customer services Michael Ash says.

“Keeping Tasmanians safe is our highest priority and we’re moving decisively to run the best possible inspection and maintenance programme to help save lives.”
