NM Group Awarded Contract to Deliver Transmission Powerline Survey to TasNetworks
NM Group are pleased to announce the award of a major new contract to confirm Tasmanian electricity transmission line capacity and check vegetation clearances to overhead conductors. This award will assist TasNetworks in maintaining the safety and reliability of supply across the state and maintaining regulatory compliance on nearly 1900 km of lines.
The powerlines will be surveyed using an array of cameras and laser scanning (or LiDAR) technologies mounted to a helicopter platform. Data is analysed in a 3D CAD environment to enable calculations of safe transmission capacity in a range of likely scenarios – ensuring safe clearances to the ground, buildings and trees. An exciting addition to the project is the delivery of the data in a dynamic 3D environment, enabling a wide access to the 3D point clouds, engineering models and multi-angle photography – through Caydence3D.
Shane Brunker, Technical Director says “As an established provider to TasNetworks, we look forward to again meeting and exceeding the expectations of our client. This project represents a great example of what I see as best practice in this area – instrumenting an aircraft with a wide range of sensor technologies and presenting the results of the analysis through an intuitive cloud platform, in addition to the standard modelling and reporting”.
Peter Johnson, Engineering Officer-Transmission Lines commented “Ensuring the safe transmission of power is critical to TasNetworks. The right technology and analysis can really assist a network business by confirming clearance distances along the network. As a result we are pleased to be working with NM Group to deliver this important project.”
