Minimizing operational shutdowns and mitigating risk is a constant concern for onshore or offshore plant/asset operators and owners of large facilities. Our 3D laser scanning survey services help capture complete as-built field construction data without causing disruption.

Intertek Surveying Services (ISS) solutions can help you meet this challenge with 3D laser scanning. We offer a unique solution that delivers high definition 360-degree by 320-degree photo-realistic panoramic scans to a 3D CAD surface model.

Our high definition 3D digital capture techniques gather a large amount of field information in a very short period of time. The process works by capturing a series of high definition 3D laser scans on site that can be processed immediately for analysis. 

Intertek deploys a vast fleet of high speed laser scanners, capturing up to one million points per second, to deliver individual “spheres” of data. Each individual scan is a high resolution “laser-point” depiction of all line-of-sight objects. Adequate scans are collected from multiple locations to satisfy all desired perspective views. The scans are individually referenced to the plant coordinates with the help of our industrial survey methodology and software system called DIMES (Data Integrated Management Engineering System). These as-built high definition 3D data sets produce a virtual plant / facility environment that can be integrated directly with CAD systems (AutoCAD, MicroStation, CADWorx, AutoPlant, SmartPlant 3D, PDS, PDMS) to interrogate and clash check against new Design Models. Elevations, measurements, coordinates, pipe diameters, and high definition photos can be extracted with the click of a mouse. Engineering groups can design directly within this data to ensure the elimination of clashes and interferences. This is opposed to the conventional alternative of relying on existing drawings that are typically not up to date.

Key areas for application include:

  • Creation up to date as-built documentation
  • 2D & 3D Modeling Services
  • 3D semi-automated modeling
  • Clash/Interference checking
  • Condition and damage assessment
  • Data exchange with many CAD platforms
  • 2D plans
  • Complete 3D CAD models from point clouds
  • Aid in inspections
  • Deformation analysis and weld peaking reports
  • Tank/vessel volumetric information

Our 3D laser scanning service is intended to enhance the design and constructability of any revamp, retrofit, upgrade project through all stages of the process. Key benefits of this service include:

  • Mitigation of risk
  • Minimizing shutdown periods
  • Minimizing offshore fabrication activities
  • Eliminate re-work and reduce cost of retrospective engineering
  • Reduction of installation man-hours
  • Maximizing field productivity
  • Minimizing field hot-work
