Abqaiq Plant 3D Scan

Abqaiq Plant 3D Scan

The project:

GAS Plant facility comprises three primary processing units – an oil processing unit, an NGL facility, and a utility unit. 

The oil processing unit consists of multiple spheroids and 18 stabilizer columns where hydrogen sulfide and light hydrocarbons are removed from the crude oil.


The mission:

As part of the close drain system project at the GAS plant, it was requested to conduct 3D laser scanning and provide the scan data and geometric CAD model in PDMS. 

The objective of the Laser scanning is to determine the above-ground features and their location. This includes Equipment, pipe rack structures, pipe, fittings and know the location of cable trays, etc. 

The captured image will be then used to determine the actual tie-in points and routing of new pipelines as per project scope. It’s also a part of the Project to do Flare Stick Inspection using Thermal Imaging Techniques.


The Execution:

The Standard Technology Used for This Project where 3D Laser scanning, which is a device that analyses a real-world object or environment to collect data on its shape and possibly its appearance (i.e. color). The collected data can then be used to construct digital, three-dimensional models.


Point cloud Scanned Over 360° with a range of 152m, the resolution density was 4mm. The total Scan Positions reached 1230 Spots, an area of 1,352,000 m² covered including Several Information Categories.


Dimensional Survey where specifically tighten using Leica Geosystems Equipment's, 1” TPS + Viva DGPS were presented as Geometric Value standards. 

Point cloud has been Registered and QC inspection using Intelligent Alignment System. Generating Full Frame Point Cloud


Customization of Piping specifications, Report formats & Border files as per Client’s requirement.

Equipment modeling, Piping modeling, and Structural modeling in order to submit the Piping Layouts, Isometrics, and BOM report.

Also, a walkthrough video was generated for the same and submitted to Client
