What is Dimensional Control?

Dimensional control surveying is the technique and science whereby 3-dimensional spaces are accurately measured to determine the area between points, creating digitally mapped distances and angles.

Dimensional control surveying has been used for decades in the worlds large jacket and fabrication facilities. However following the Piper Alpha disaster in the North Sea in 1988 in which 167 men lost their lives, Dimensional Control survey began to be used on offshore installations, as the subsequent enquiry found that one of the causes of the fire was naked flame from offshore fabrication, welding and grinding in a highly explosive environment. Dimensional Control survey eliminates the need for this.

Suitable for application in:

  • Industrial Measurement – 3d capture
  • Replacement Pipe-work – Clash checking
  • Topographical surveys – Mining surveys
  • Alignment surveys – Structural steel surveys
  • Drill rig alignments – Structural monitoring
  • Fabrication Surveys – Ship repair/building
  • Laser scanning – 3d modeling

Dimensional control can be defined as the process of acquiring accurate dimensional documentation that is spatially referenced to a known or established benchmark. Using the latest survey technology from Leica Geosystems 3BCSL Surveyors can measure and produce 3d Cad models from single pipe spool replacements to full FPSO/Jacket construction surveys.

The captured data can be transformed to a clients preferred format, offering quick and easy data evaluation and problem checking. As we offer a full draughting service, we can provide full 3D models using AutoCAD or Micro-station, 2D drawings or Point Cloud data from our Laser Scanners. Our workforce globally totals 30 experienced surveyors bringing with them decades of experience in the field of Engineering and Land survey.
