Confined Space Inspection Services help owners collect visual and spatial evidence before committing personnel to difficult interiors.
Remote inspection is a control—not a universal exemption. The space, hazards, access, operating state and work scope still require assessment. Ven-Tech plans the robotic task around isolation, hazardous energy, atmosphere, contamination, communications, launch and recovery, and the client’s site program.
Collision-tolerant aerial systems can reach elevated and complex areas. Crawlers provide stable contact inspection along floors, walls, pipes and magnetic surfaces. ROVs address flooded or submerged zones. LiDAR, SLAM, video and photogrammetry can be combined when the geometry and environment support them.
The project begins with the decision: visual condition, coverage confirmation, dimensions, deformation, deposits, obstruction, baseline mapping or maintenance planning. Ven-Tech states what was observed, what remained inaccessible, how measurements were referenced and where another method or controlled entry is required.
Remote-first assessmentMulti-platform deploymentDocumented coverage & limits
Follow a planned route and monitor video, map growth and system health while the team can reacquire gaps.

Robotic inspection platforms
Fly. Crawl. Swim.
Recover deliberately.
Confined Space Inspection Services can combine aerial, tethered, crawler and underwater platforms according to geometry, environment, traction, communications, payload and recovery needs.
01FLIGHT / VISUAL / LIDAR
Collision-tolerant inspection drone
Protected aerial platforms support close visual inspection and project-selected mapping in dark, GPS-denied spaces. Access size, airflow, dust, moisture, temperature, radio conditions, obstacles, endurance and recovery route are confirmed first.
02ENDURANCE / RECOVERY
Tethered & specialty aerial systems
Tethered or mission-specific platforms can support extended observation, controlled retrieval or specialized environments where the asset and access permit. Cable management, snag risk and emergency recovery remain part of the plan.
03SURFACE / WET / PIPE
Crawlers, ROVs & magnetic platforms
Crawlers and ROVs extend remote inspection into pipes, tanks, wet wells, partially flooded structures and surfaces where flight is impractical. Camera, sonar, lighting, measurement and recovery options follow the scope.
04REGISTER / VERIFY / REPORT
Mapping & review workstation
Video, stills, LiDAR, SLAM trajectory, measurements, annotations and asset references are reviewed together. Processing creates project-selected point clouds, models, plans, sections, defect registers and reports.
Six-stage inspection workflow

Reduce entry.
Keep the controls.
Robotic deployment changes exposure—not the need for disciplined planning.
WorkSafeBC’s Part 9 guidance requires employers to identify confined spaces and determine whether worker entry is required. CCOHS guidance emphasizes a space-specific hazard assessment and control program, including roles, hazards, monitoring, procedures and emergency response when entry is involved.
Ven-Tech coordinates the remote inspection method with the applicable jurisdiction, owner program and worksite controls. The technical report separates confirmed observations, approximate or controlled measurements, inaccessible areas, data limitations and tasks requiring another method.

Confined Space Inspection Services FAQ
Plan the inspection
with confidence.
These answers are a practical starting point. Ven-Tech confirms access, hazards, controls, platform, sensor, recovery, coverage and deliverables for the actual asset.
What are Confined Space Inspection Services?+
Confined Space Inspection Services use project-suitable drones, crawlers, ROVs, cameras, LiDAR and mapping systems to collect visual and spatial evidence inside difficult enclosed assets. The method is selected around access, hazards, geometry, environment, coverage and the client’s required decision.
Can robotic inspection eliminate confined space entry?+
Remote inspection can eliminate or reduce some planned entries, but it does not automatically remove the legal classification, site controls or need for future entry. The employer and project team must still identify the space, assess hazards and determine the controls required for the actual work.
How accurate is confined space 3D mapping?+
Accuracy depends on the sensor, geometry, range, surface reflectivity, dust, moisture, motion, SLAM trajectory, loop closure, control, registration and processing. Ven-Tech defines whether the result is visualization, relative geometry, measured mapping or a controlled survey product before acquisition.
What assets can be inspected?+
Suitable assets may include tanks, reservoirs, silos, vessels, chambers, tunnels, shafts, culverts, sewers, pipelines, penstocks, process spaces, marine voids and mining infrastructure. Access, dimensions, atmosphere, contamination, operating state and recovery requirements determine feasibility.
Can the systems inspect wet or partially flooded spaces?+
Yes, when a project-suitable platform and controls are available. A collision-tolerant aerial drone may inspect above the waterline, while an ROV or crawler can address submerged or contact-based areas. The scope defines electrical, contamination, tether and recovery controls.
What defects can remote systems identify?+
High-quality imagery can document visible corrosion, coating loss, deposits, cracks, deformation, leakage evidence, loose components, obstructions and weld or support condition. Detection depends on access, lighting, range, surface cleanliness, image quality and the size and orientation of the feature.
What deliverables are available?+
Depending on scope, Confined Space Inspection Services can provide indexed video, inspection stills, defect registers, LiDAR point clouds, 3D meshes, plans, profiles, sections, measurements, coverage maps, CAD or BIM-ready exports and a technical report with limitations.
What information is needed for a proposal?+
Provide the asset type, location, operating state, access opening, internal dimensions, drawings, known hazards, isolation status, atmosphere or contamination concerns, priority areas, smallest required feature, mapping or measurement needs, schedule and deliverable formats.
