Our Core Services
1. Commercial Diving Operations
Ven-Tech Subsea’s Underwater Contractors Edmonton team provides comprehensive surface-supplied commercial diving services, including inspection, maintenance, construction, and repair. Our divers are trained and certified under CSA Z275.2 and WorkSafe Alberta standards, ensuring complete compliance and safety.
We perform underwater inspections for reservoirs, hydro facilities, pipelines, and outfalls, using full surface-supplied dive systems with live CCTV monitoring, voice communication, and gas analysis. This guarantees visibility, safety, and quality control on every job.
2. ROV and Sonar Inspection
Our ROVs are designed for precision inspection and data collection in environments where diving may not be practical or safe. The Underwater Contractors Edmonton team operates Deep Trekker Revolution ROVs equipped with HD cameras, sonar imaging, and LED lighting for real-time monitoring and recording.
We conduct condition assessments, sediment mapping, and infrastructure surveys for pipelines, outfalls, and reservoirs. Data captured from these missions supports engineering reports, maintenance planning, and environmental monitoring.
3. Reservoir Cleaning and Maintenance
Ven-Tech Subsea’s reservoir cleaning services allow for full internal cleaning and inspection without draining or disrupting service. Our Underwater Contractors Edmonton team uses vacuum utility crawlers and robotic cleaning systems to safely remove sediment, sludge, and biofilm buildup.
For potable water systems, we follow AWWA C652-19 standards for disinfection and entry, ensuring compliance and water quality integrity. For non-potable and industrial systems, cleaning is conducted under NFPA 25 and environmental best practices to ensure minimal operational downtime.
4. Underwater Welding and Repairs
Our team includes CWB and CSWIP-certified underwater welders who perform both wet and dry welding operations. Whether repairing intake screens, reinforcing structures, or replacing corroded components, Ven-Tech Subsea’s Underwater Contractors Edmonton team delivers precision, safety, and quality workmanship in every repair.
5. Hydrographic, Bathymetric, and Environmental Surveys
Using multibeam sonar, side-scan imaging, and photogrammetry, our Underwater Contractors Edmonton technicians collect detailed underwater data for engineering and environmental applications. This technology allows us to create accurate 3D maps and models of submerged infrastructure, sediment buildup, and reservoir geometry.
These surveys are invaluable for engineering design, regulatory compliance, and long-term maintenance planning.
