As forest companies come to appreciate the versatility of drones as a management tool, more of them are opting for ownership of their own unmanned aerial vehicles. Pinnacle Renewable Energy Inc., an operator of wood pellet manufacturing plants in the interior of British Columbia, has recently invested in its own drone. The machine’s principal objective is for use as a volumetric assessment tool.
Traditionally, the measurement of large stockpiles of woody materials required for the pellet manufacturing process has been a land-based system. It is a time consuming exercise of varying accuracy with worker safety implications.
Pinnacle Renewable Energy wanted to find a more efficient method of attaining the data it required.
“We started hiring drones from third parties,” recalled Erik Marchand, operations controller for Pinnacle, which is based in Prince George, B.C. The results produced by the drone were impressive but expensive, he added.
After some number crunching and payback assessment, Pinnacle decided to invest in and operate its own drone. Pinnacle turned to InDro Robotics Inc., in Calgary for help. InDro Robotics is a Canadian company fully accredited by the federal regulator to offer a range of remote sensing functions including an operation and training package for drone use, explained Matt Stambaugh, vice-president for UAV operations with the company. In fact, InDro Robotics was recently awarded the very first full compliant SFOC (Special Flight Operations Certificate) in Canada, which allows the company to carry out complex operations nationwide in logging and other industries.
“The function for Pinnacle was primarily as an inventory measurement tool,” said Stambaugh. “Drones can provide a really efficient visual management platform. At the end of a five day engagement, (the trainee operators) had a lot of confidence in their drone flying skills. Maintaining the height of the drone’s flight is really important,” he cautioned.
InDro Robotics trained five of Pinnacle’s people in drone operation and management. “It’s very easy technology to actually use,” reported Marchand. “The regulatory environment and navigating that on your own is a lot more demanding. But InDro Robotics is a great company to work with.”
The drone and its associated computer software makes easy work of Pinnacle’s volumetric assessment challenges. Programming the drone, collecting the data, uploading it into the computer to produce an accurate 3D volumetric image takes about two hours total, said Marchand. “It’s unbelievable. The process is also safe and eliminates human error.”
Marchand reckons Pinnacle’s drone will prove useful in other applications. The residual wood piles of bark, sawdust and shavings used to manufacture energy-efficient wood pellets, can generate internal heat. A drone fitted with a thermal imaging camera can accurately detect hot spots for remedial action. “Within our operations, we have several larger structures which periodically require inspecting,” he continued. The drone coupled with a high definition video camera can quickly and easily provide the detailed information required without potentially dangerous human access.

Simple, clean and efficient were the guiding principles for B.C. logger Gregory Jacob when he began his examination of available steep slope log harvesting methods. He was able to get exactly that, and the key new machine in Gregory’s steep slope arsenal is a wheeled John Deere 1910E cut to length forwarder with a Haas winch.

Up in smoke—not
A new sawmill came on stream this spring in the B.C. Interior—thanks to the co-operation of three forest industry parties—and the end result is that wood fibre that would have been piled and literally gone up in polluting smoke will now be converted to viable wood products.
