Revolutionising Vessel Inspections with Snowcat & Argus
Are you ready to transform your vessel inspection strategy? With Nexxis’ Snowcat and Argus, you can now capture HD visuals, high-accuracy 3D maps, and digital twin models—all in a single deployment.
The Challenge: Traditional Inspections are Costly and Risky
Inspecting tanks, vessels, or large industrial assets has typically required confined space entry, scaffolding, rope access, and extended shutdowns—often with repeat inspections to verify initial findings. It’s time-intensive, risky, and inefficient.
That’s why more service providers are moving to robotic platforms like Snowcat paired with Argus 3D SLAM—delivering safer access, deeper data, and lower total inspection costs.
How It Works
The Snowcat robotic crawler uses a powerful magnetic track system to navigate curved, vertical, and overhead surfaces of tanks and vessels. Its integrated HD camera system captures detailed close-range visual data.
Simultaneously, the Argus SLAM payload (powered by cutting-edge 3D LiDAR and IMU technologies) maps the internal structure of the asset, generating a high-fidelity point cloud and digital twin.
Data is transmitted live via a Kevlar-reinforced fibre tether, giving operators real-time visibility and enabling remote operation—without the need for internal access or shutdown crew exposure.
What You Get from a Single Deployment
- HD visual data on corrosion, welds, cracks, coatings and surface defects
- 3D SLAM-based digital twin with centimetre-level accuracy
- Geo-tagged inspection points linked directly to asset geometry
- Traceable, repeatable inspection paths—ideal for change tracking
- Complete asset coverage—no missed areas or guesswork
Every mission is precisely repeatable, enabling condition monitoring across time and improving decision-making.
Why It Matters: From Inspections to Intelligence
Snowcat and Argus aren’t just about data collection—they’re enabling predictive maintenance.
Can you say with confidence what your vessel looked like 6 months ago? Are you spotting defects before they become shutdown events?
By capturing a full 3D record and spatially tagged visuals every time, Nexxis empowers you to:
- Track deterioration across multiple shutdowns
- Detect changes in corrosion, coating failure, or structural deformation
- Plan maintenance based on trends—not assumptions
- Reduce unplanned outages, rework, and safety exposure
- Extend asset life while optimising inspection spend
Smarter. Safer. More Scalable.
With robotic mobility, HD remote visual inspection, and real-time 3D mapping all in one platform, Snowcat + Argus delivers a smarter, safer, and more scalable way to inspect tanks, vessels, and complex confined spaces.
Whether you’re maintaining critical infrastructure or driving digital transformation through asset intelligence—this is the future of inspection.
