Comprehensive and Precise Data Capture

Traditional methods, such as theodolites or total stations, are limited to point-specific measurements.
In contrast, 3D scanners offer full coverage of the entire structure. A single scanning session can capture millions of data points,
enabling the creation of a high-resolution 3D model. This approach reduces time spent on-site while increasing the precision of the analyses.
Uses : 3D scanning is used to measure dimensions such as the distance between two guides or between two teeth, ensuring precise and accurate results critical for mechanical analysis and quality control.

Deformation Analysis Under Stress

Understanding how a steel structure behaves under stress is crucial to avoiding severe problems.
3D scanners allow comparison of a structure’s unloaded (neutral) state and its stressed state by overlaying captured models.
This helps visualize deformations and differentiate them from expected tolerances.

Example: An offshore platform was scanned to measure the verticality of its structural legs.
The technology revealed subtle deviations, invisible to the naked eye, that could compromise the stability of the structure.

Comparing Scans to Identify Displacements

Differences between two scans, performed at different times or under different conditions, help pinpoint precise changes in the structure.
This is particularly useful for detecting displacements or gaps resulting from environmental or operational constraints.

Illustration: A comparative analysis was conducted on an offshore platform to evaluate the state of structural components
after an operational period. Critical displacement zones were quickly identified and rectified.

Case Study: During the examination of an offshore platform leg, scanning identified deformations caused by a 15-ton load.
These deviations were analyzed to implement targeted reinforcements and prevent future risks.

– Time Efficiency: Rapid scans reduce on-site interruptions.
– Portability: Ideal for challenging environments like offshore platforms.
– Post-Project Analysis: Digital data serves as a twin for future analysis or design modifications.
