Remote Sensing & Technology

Ballard’s inspection team has experience throughout the country, and internationally, conducting scheduled and emergency inspections on energy, industrial, infrastructure, and maritime sector projects with experienced and certified divers. Ballard also performs many underwater projects utilizing Remotely Operated Vehicles (ROV), imaging sonar and laser scanning to increase safety and cost-efficiency. Through the use of a sophisticated Autonomous Underwater Vehicle (AUV), we can collect multibeam, side-scan, bathymetric, water sensor, and internal positioning data (GPS, INS, DVL) within very tight tolerances.

The Ballard team are experts at applying the right technology for the specific project and strive to limit diver exposure to underwater operations on hydroelectric projects and other sub-aqueous facilities where head pressure differential and active equipment issues make manned operations more sensitive.
