Object acquisition (NO CONTACT SYSTEM) This instrument allow

plant, in full safety, thanks to no contact system

The instrumentation 3D Laser Scanner allows you to have a

3 Object acquisition (NO CONTACT SYSTEM) This instrument allow to work without having to interrupt the production cycle of plant, in full safety, thanks to no contact system technology, which allow to acquire objects over 100 mt. The instrumentation 3D Laser Scanner allows you to have a complete and precise data acquisition facilitates the design and phases of action

4 Points cloud acquired by Laser Scanner 3D Modeling of points cloud to realize the 3D model Higher is the requested resolution (more details), higher will be the cloud density

beams, etc) can be geometrically modeled as per tables agreed with the Client

5 POINTS CLOUD With the 3D software is possible to model civil structures, plants on the land or off shore 3D PLANT MODEL The various elements (such as flanges, pipes, beams, etc) can be geometrically modeled as per tables agreed with the Client (ASME, ANSI, DIN, AISC, etc). The generated model can be utilized on other 3D softwares.

to import the points cloud in the used design

6 Possibility to find interferences between the real status and the design (this is due to the possibility to import the points cloud in the used design software) Possibility to model the points cloud only where necessary

7 Conversion from points cloud to 3D model for structures

8 Possibility to post elaborate the acquired data with Cyclone software or other applications such as Autocad, Revit, Maya, Microstation, PDS, PDMS and SmartPlant 3D, all with Cluodworx plug in

3D model perfectly sized and positioned; 3.

Simulations and analysis of installation

9 APPLICATIONS 1. Data As Found generated by points cloud; 2. 3D model perfectly sized and positioned; 3. Design support; 4. Simulations and analysis of installation alternatives (to be used to minimize problems during the construction phase); 5. Inspection during the construction; 6. Verification of the changes in the course of time; 7. Construction of 3D virtual model; 8. Safety.

10 ADVANTAGES 1. With the 3D model obtained by laser scanning is possible to measure instantly on the PC; 2. Thanks to instrumentation 3D laser scanner the survey is objective and not more subjective; 3. Project studies are simpler, starting directly from a 3D model real and full; 4. The acquisition phase is safety done thanks to no contact system utilized by 3D laser scanner, which allow to detect objects at distances over 100 m. at high temperatures, and in dangerous or not accessible places; 5. The generated 3D model can be used in many fields of applications e.g.: maintenance, engineering, process verifications, construction, training, etc...; 6. The generated data may be used with many CAD software such as Autocad, Revit, Maya, Microstation, PDS, PDMS, SmartPlant 3D, PlantSpace, AutoPlant, ProE etc...; 7. Cost reduction in survey procedure and in 3D model creation; 8. The 3D Laser Scanner technology allow to acquire data without any interruption during plant operations; 9. The high quantity of data acquired, remove the risk to having to return on site for making other measurements; 10. The 3D Laser Scanner technology reduces the periods as regards the work on existing plants such as enlargements, revamps, retrofits, etc...; 11. Reduction of parts mounting time, because you can define in the office the right paths within the plant to follow, eliminating the risks of find obstacles that prevent the assembly or the passage of parts required; 12. Thanks to network connection you can control in real time the acquired data; 13. The 3D Laser Scanner technology, eliminates the error of recognition of the geometries, shapes and positioning of the objects.

12 SURVEY PROCEDURE 1: Identification of the areas to be scanned; 2: Materialization of closed polygonals to use as a reference for topographic calculation;

13 SURVEY PROCEDURE 3: Creating a network of polygonals connected to the main already georeferenced to acquire targets topographically; 4: Executing of various laser scans in order to cover all areas to survey;

14 SURVEY PROCEDURE 5: Topographic calculation with specific softwares; 6: Registration and georeferencing of the laser scans into a single points cloud database

15 7: Creation of a single points cloud database; SURVEY PROCEDURE
