3D Laser Scanning & Dimensional Inspection
Engineering inspection supported by high-density 3D scan data.
Engineering inspection supported by high-density 3D scan data.
This service is useful when the client needs more than just raw scan data. Trainopedia can support the full workflow from field scanning through dimensional analysis and reporting.
The objective is to verify actual condition, identify deviations, compare geometry against defined reference criteria and provide a structured engineering output that can support inspection, maintenance, fabrication review, revamp planning or as-built verification.
Non-Contact Inspection
Capture complete geometry safely and efficiently without depending only on manual measurement.
Large Surface Evaluation
Useful for tanks, vessels and other equipment where full-surface dimensional behaviour matters.
Deviation Identification
Understand where the equipment is within tolerance and where local distortion requires attention.
Engineering Documentation
Present findings through visuals, analysis tables and a structured dimensional inspection report.
Scope of services
Final scope depends on the software platform, project phase, client standards and available inputs.
Tanks & Cylindrical Vessels
Roundness, ovality, plumbness, verticality and deformation analysis for large cylindrical assets.
Nozzle & Interface Verification
Support dimensional checks of nozzle locations, interface points and connection references.
Skids & Package Equipment
Dimensional verification of packaged assemblies, structural members and installation interfaces.
Fabricated Equipment
Check shape, alignment, fit-up and dimensional conformity of fabricated components or assemblies.
Piping & Large Assemblies
Support verification of spool geometry, routing reference, tie-ins or interface match conditions.
Structural & Support Checks
Review dimensional positions of members, supports and selected structural reference features.
Project execution workflow
Each stage can be adjusted to suit the client's project controls, review cycle and software environment.
Requirement Review
Understand equipment, inspection objective, tolerance basis and reporting need.
Reference Setup
Confirm tag, zero position, orientation, datum and required scan coverage.
3D Laser Scanning
Capture the required surfaces from suitable field scan positions.
Point Cloud Processing
Register, align, clean and prepare the point cloud for analysis.
Best-Fit Geometry & Analysis
Create reference geometry and check roundness, ovality, diameter, plumbness or verticality.
Deviation Mapping
Generate colour maps, unrolls, sectional views and other visual analysis outputs.
Tolerance Verification
Classify results against code, drawing or client-defined tolerance limits.
QA / QC & Final Report
Review calculations and graphics, then issue the dimensional inspection report.
What we typically need from the client
- Equipment tag / identification and location
- Inspection objective and parameter to be checked
- Applicable code, drawing or tolerance criteria
- Required reporting format
- Reference drawings or geometry, if available
- Area / equipment access and scan limitations
- Required coordinate or orientation reference
- Site safety and execution conditions
Exact input requirements depend on the project scope and available site or project information.
Typical project deliverables
- 3D scan-based dimensional inspection report
- Point cloud-based reference visuals
- Best-fit geometry analysis
- Colour deviation maps
- Unrolled surface views
- Roundness / ovality tables
- Plumbness / verticality findings
- Out-of-tolerance identification
- Engineering summary and observation notes
Final deliverables are confirmed during scope definition and aligned with the client's documentation standards.
