Laser Mapping is a non-contact, non-destructive technology that digitally captures the shape of physical objects using lasers. Reflector dots are placed all around the object for orientation reference points. The lasers reflect off the dots capturing a physical object’s exact surface characteristics and complexion and converts it into a digital 3-dimensional representation.
3D laser scanning is especially suited to the measurement and inspection of contoured surfaces and complex geometries where physical, mechanical measurement is difficult or impossible. A traditional measurement method or a touch probe could not obtain the massive amounts of data made possible by Laser Mapping.
Applications for Laser Mapping
The technology is ideal for a number of applications:
- Tank surveys including measurement of dents, floor ripple and slopes, settlement, and volume.
- Settlement and other measurements to API-653, EEMUA-159 or as required.
- Coke drum scans can determine bending, bulging, and lean.
- Comparison of new and old nozzles and pipe spools to check the before installation fit.
- Production of as-built measurement for refurbishment and replacement projects.
- Volumetric dimensons of product stockpiles.
- Corrosion evaluation of pipelines, pipinmg, vessels, etc.
Advantages of Laser Mapping:
- Non-contact measurement
- Automated data acquisition
- Interchangeable sensors allowing quick changeover to new barrels
- Full-featured analysis and reporting functions
- Provides reliable and accurate repeatable results which are traceable for future asset integrity analysis
- Full-length bore mapping
- Complete surface characterization
- Photography quality bore and chamber image using laser video imaging
Limitations of Laser Mapping:
- Expensive instrument
- Actual set up of equipment can be labor intensive
- Requires enough clearance from the surface to be modeled (about 18”)
