Ven-Tech Subsea delivers precision underwater mapping and non-contact inspection solutions through our advanced multibeam imaging sonar services. Utilizing a fleet of cutting-edge sonar systems—including the Blueprint Oculus C550D, M3000D, and a diverse range of Norbit Multibeam Sonars (see Norbit systems)—we provide ultra-high-resolution imaging for a wide spectrum of subsea applications. These sonars are seamlessly integrated with our Deep Trekker ROVs, Unmanned Surface Vessels (USVs), and robotic pipe crawlers, enabling rapid deployment in confined, remote, or hazardous environments.
Our Oculus C550D (Blueprint C550D) delivers real-time imaging at dual frequencies (750kHz and 1.2MHz), allowing for optimal balance between range and detail—ideal for structural inspections, scour analysis, and search operations. The M3000D model offers ultra-high frequency sonar (3MHz) for sub-centimeter resolution imagery, supporting applications such as weld inspection, sediment profiling, and biological growth monitoring in zero-visibility water.
For broader bathymetric surveys and 3D terrain modeling, our Norbit systems offer industry-leading accuracy and swath coverage, critical for hydrographic surveys, dredging QA/QC, port infrastructure inspection, and channel clearance. With RTK-GNSS integration and motion compensation, these systems enable real-time georeferenced data acquisition with millimetric precision.
-Asset integrity inspections for dams, bridges, piers, and pipelines
-Pre- and post-dredging surveys
-Sediment buildup mapping and reservoir capacity assessments
-Search and recovery missions in zero-visibility environments
-Biological fouling evaluation on intake structures and outfalls
-Underwater construction QA/QC and change detection
Every deployment is supported by our CSA Z275.2-certified dive team, certified ROV/USV operators, and experienced sonar technicians. Deliverables include processed 3D models, sonar mosaics, high-density point clouds, and professional reporting with actionable insights for engineering and asset management teams.
With 10+ years of operational excellence, BCCSA COR certification, and service history with organizations like BC Hydro, Husky Energy, Shell Canada, and Indigenous Services Canada, Ven-Tech Subsea stands as a trusted leader in high-resolution sonar inspection and survey operations.
Our multibeam sonar capabilities are driven by top-tier imaging systems, enabling detailed hydrographic surveys, asset inspection, and 3D volumetric mapping. Our arsenal includes:
Blueprint Oculus C550D: A dual-frequency sonar that delivers up to 2,000 beams per second with outstanding clarity in low-visibility and turbid conditions. Ideal for underwater structure inspections, pipe assessments, and marine navigation.
Blueprint Oculus M3000D: High-definition sonar optimized for confined space and tunnel inspections, capable of penetrating heavy turbidity and silt.
Norbit Multibeam Systems: We operate multiple Norbit sonars including the iWBMS and iSTX series, engineered for shallow and deep-water hydrographic surveys, pipeline route planning, bathymetric mapping, and environmental assessments.
Each system is mounted to the most effective deployment platform for the project: Deep Trekker ROVs for confined underwater inspections, autonomous surface vehicles (USVs) for broad area mapping, or our pipe crawlers for submerged tunnel and conduit evaluations. Multibeam Imaging Sonar Services
