Redefining Confined Space and Hull Digital Inspection
A Safer Approach to Fleet Integrity
For offshore operators and shipping companies, hull integrity is not simply a maintenance requirement. It is a safety, operational and financial priority.
Through its drone division ROAV7, part of STAPEM Group, advanced digital inspection technologies are deployed to improve safety, enhance data accuracy and reduce operational constraints in confined and high-risk environments.
Hull Digital Inspection integrates:
- High-accuracy visual inspection through photogrammetry
- 3D digital twin creation using LiDAR
- Internal inspection of ballast tanks and confined spaces using collision-tolerant drone systems
- Ultrasonic Thickness Measurement performed directly by drone
These technologies enable the detection of corrosion, cracks and structural degradation without mobilizing personnel inside complex or hazardous spaces.
Interview - Gabriel Deguine, Operations Manager Africa, ROAV7
As part of the technology presentation, Gabriel Deguine shared his perspective on the evolution of digital inspection workflows:

Integrated Digital Inspection Workflow
The confined-space inspection platform combines high-definition visual capture, LiDAR-based 3D mapping and integrated ultrasonic thickness measurement within a single drone-based workflow.
Designed for metallic and GPS-denied environments, the system allows precise localization of thickness readings, real-time validation of structural condition and structured integration of data into a digital twin of the asset.
By merging visual inspection, 3D modeling and structural assessment in one operation, ROAV7 delivers engineering-grade data while significantly reducing human exposure in confined environments.
From Inspection Footage to Actionable Data
ROAV7’s approach goes beyond image capture. It integrates acquisition, measurement, modeling and reporting into a coherent digital inspection framework.
The outcome is structured, location-tagged integrity data that supports informed maintenance planning, risk mitigation and long-term asset management strategies.
By mastering confined space drone technology and integrated thickness measurement capabilities, STAPEM Group strengthens its position in advanced offshore digital inspection solutions across Africa and international markets.
