At Brennan, we leverage advanced technology to enhance safety, efficiency, and insight, both above and below the waterline. Our investment in ROVs, acoustic imaging, and stereo camera systems enables us to perform detailed inspections in environments that may be unsafe or inaccessible for divers. These tools help clients save time, reduce risk, and gain a deeper understanding of their underwater structures before anyone enters the water.
ROVs
Equipped with high-definition cameras and sonar imaging, our remotely operated vehicles (ROVs) play a vital role in pre-dive planning, confined space inspections, and asset condition monitoring. Each unit can be fitted with specialized tools, including pressure washers, manipulator arms, dredging gear, and thickness gauges, for versatile, efficient underwater operations.
Acoustic Imaging
Our advanced 360° sector scans and side-scan sonar systems deliver high-resolution visuals even in zero-visibility conditions. From 3D point clouds to photorealistic underwater scans, this technology allows us to precisely identify, map, and assess submerged assets and site conditions.
Stereo Camera Systems
Brennan’s stereo camera technology captures ultra high-resolution video and crisp still images, supporting 3D modeling and point cloud generation. These systems provide accurate, measurable visuals of submerged assets, even in near-zero visibility, enabling precise analysis and reliable documentation.
