Ven-Tech Subsea brings together surface-supplied divers, underwater video systems, robotic platforms (ROVs and crawlers), and CSA-compliant safety procedures to ensure professional results in even the most demanding underwater environments.
Core Services Provided by Our Commercial Diving Contractor Team
✅ Underwater Inspections
We provide detailed visual and video inspections of reservoirs, pipelines, intakes, outfalls, bridge piers, and caissons. Our teams use helmet-mounted cameras, sonar, and ROVs to ensure nothing is missed.
✅ Maintenance & Cleaning
We remove sediment and biofilm from potable and industrial water tanks using suction dredging, pressure washing, and vacuum systems—all performed while keeping the system online.

From underwater welding to valve replacement and U-bolt installation, we perform structural repairs in a variety of conditions—including zero-visibility and confined spaces.

Using Deep Trekker ROVs, sonar imaging, and pipe crawlers, we supplement dive teams with remote systems that improve inspection quality and reduce risk in hazardous conditions.
