APA recently trialled drone-based methane detection at our Dandenong LNG facility. This marks the first time Bridger Photonics has deployed its drone technology in Australia.

The survey used Gas Mapping LiDAR (GML) to identify methane emission sources down to 0.5kg/hr with 90% probability of detection. We surveyed the Dandenong LNG facility. Traditionally, we have used helicopters for methane measurement surveys. However, in populated areas like Dandenong, aviation regulations require helicopters to fly above 1,000 feet, which can limit the sensor’s resolution.

This technology provides our teams with a detailed map of emissions, including precise geographic coordinates, emission rates, and the source height above ground level.

Using drones allows us to monitor smaller assets more cost effectively than using a helicopter. It is a practical step in our commitment to more accurate reporting and reducing our operational footprint. We are now reviewing the drone survey data to understand how this technology can support our broader emission reduction goals across our portfolio. We look forward to continuing our partnership with Bridger Photonics as we evolve our detection capabilities across our network.
